JSWAS A-2 – 1999



Jacking Reinforced Concrete Pipes for Sewerage Commentaries This Standard specifies the requirements for reinforced concrete pipes for sewerage, which are installed by the jacking method.



This Standard was first established in 1973, and numerous revisions has been made thereafter. The initial versions have specified in detail the requirements for the joint shape and dimensions. However, over the years, the technology related to the jacking methods have developed significantly, such as long-distance jacking, curved jacking, and numerous techniques to answer to all types of soil conditions. In response to such developments, improvements have been made to the pipes, including various designs of joints.



Under such circumstances, and in awareness of the trend in international standards, this revision has been made on the basis of performance criteria. In this respect, there is a major change in the regulatory methods. Even so, aspects such as internal diameter, thickness, and effective length has remained the same as standard dimensions, in consideration of the existing jacking equipments.



The pipes are classified into the Standard Pipe and Intermediate Jacking Pipes (hereinafter “Intermediate Pipes”), and further subclassified into “50” or “70” for concrete compressive strength of pipe, Class “1” or “2” for external strength, and JA, JB, or JC for joint specification. The range of specified nominal diameters have remained the same, with Standard Pipe as 800~3000mm, and Intermediate Pipe as 1000~3000mm.



1. SCOPE The pipes to which this Standard applies are those factory-manufactured by centrifugal force (spinning method), roller-pressing method utilizing round-section rotation bars to compact the surface of the concrete, and vibration method. These pipes shall satisfy all the requirements as set forth in this Standard.



2. CLASSIFICATION The type of the pipes comprise the generally used Standard Pipe, and that which are used for part-way jacking; Intermediate Pipes. The range of specified nominal diameters have remained the same, with Standard Pipe as 800~3000mm, and Intermediate Pipe as 1000~3000mm.



In order to suit the external loading requirements that generally differ in accordance with the depth of the installation, Class 1 and Class 2 designs are available. Class 2 is designed to accommodate



15



double the cracking load of Class 1 pipes.



Type-S Intermediate Pipe is not sub-classified (to Class 1 or 2) owing to it steel-pipe nature. Type-T Intermediate Pipe is a steel-and-concrete composite structure, and classified into Class 1 and Class 2, in a similar manner as Standard Pipes.



In addition, the compressive strength of concrete for the pipe is available as “50” and “70”. Class 1 Standard Pipe is made available for both strength levels.



“50” refers to the compressive strength



of concrete of the pipe: minimum 50N/mm2, and corresponds to the formerly-recognized minimum 500kgf/cm2. Similarly, “70” refers to minimum 70N/mm2 (formerly minimum 700kgf/cm2).



Furthermore, this revision includes for the first time the requirements for the joint performance. This has been necessary in view of the increasing jacking pipe works at great depths and consequently the necessity to respond to higher groundwater pressures. A larger extraction-length at the joint has also become necessary due to tighter curve-jacking. Section 3.4 details the requirements for joint performance.



Class 2 – 70 for Standard Pipe is not specified owing to the fact that it is not commonly required, as well as for the higher level of production technology required to manufacture this type of pipe. Intermediate Pipe Class 1 – 70 is also not specified owing to installation reasons related to the intermediate jacking capacity and its arrangements.



3. QUALITY The former Section 3.4 “Water Tightness” has been changed to “Joint Performance”, wherein water pressure resistance and extraction length are specified.



3.1



Appearance “Detrimental flaws” shall refer to aspects that will adversely affect the functional strength of the pipe, water-tightness, and durability. The internal surface of the pipe shall not have rough nesses that will impede the flow. However, it is not necessary to provide additional finish (such as cement paste) to make the surface particularly smooth.



3.2



External Strength External strength values are unchanged. Cracking strength for Class 2 is 2 times that for Class 1. Breaking strength is 1.5 times the cracking strength.



External strength is not applicable for Type-S Intermediate Pipe owing to its steel material nature. However, cracking strength is applicable for Type-T Intermediate Pipe as it is a



16



steel-and-concrete composite design.



3.3



Concrete Compressive Strength of Pipe This section has formerly been titled “Concrete Compressive Strength”. This revision is made due to the fact that it is the strength of the concrete in the pipe body that is the subject of the quality characteristic. This is confirmed by the inspection requirements described in Section 8.5 “Concrete Compressive Strength”. As previously specified, the concrete compressive strength of pipe are minimum 50N/mm2 (minimum 500kgf/cm2) and minimum 70N/mm2 (minimum 700kgf/cm2). In principle, the axial bearing capacity of the pipe is calculated based on these strength values.



In consideration of the differing concrete mix and curing methods depending on the manufacturing factory, the concrete compressive strength shall refer to the age at the point of product delivery.



3.4



Joint Performance Joint performance is categorized into JA, JB, and JC (3 types), for which water pressure resistance and extraction lengths has been specified.



It has been common in the past to require water pressure resistance of 0.1 MPa for jacking pipes, but owing to the increasing requirement for higher pressure performance, requirements for 0.2 MPa has been specified in this Standard.



“Extraction length” shall refer to the gap between the jointed pipes. Along with the increasing distance of jacking installation and related imposition of various conditions, tight-curved jacking are also becoming common. Under tight-curved jacking, since the gap of the joint occurring at the outer circumference of the pipes are made even wider, such gaps need to be specified as extraction lengths.



Further, in order to confirm the performance of the joint for earthquake resistance, the Joint Model Test Regulation includes the requirements for composite water-tightness test, in which extraction lengths are indicated for Level 2 earthquake conditions. The objective of this test is to confirm the water tightness of the joint, and that the internal flow is maintained, in a curve-jacking arrangement under Level 2 earthquake conditions; the essential point being the additional extraction at the joint expected under such seismic situations. The details of this test is as prescribed in “ Principles Related to Earthquake Resistance for Sewerage Facilities, and Commentaries”. 2 pipes are jointed normally, after which a deflection is introduced. The



17



joint gap at the internal circumference of the deflection is extracted to a length of 37mm (“earthquake-situation extraction length”). The joint gap at the external circumference of the curve is positioned to the basic curve-jacking extraction length + earthquake-situation extraction length. The testing apparatus is fitted to the outer line of the joint, water is applied to the specified pressure, and visual inspection for leakages is conducted. 37mm is the extraction length for each pipe with the assumption of 1.5% of permanent strain in the soil under earthquake situation ( 2430mm x 0.015). [Refer to Appendix 1 “Joint Model Test Regulations”; ”Test Method”].



The values for water pressure resistances and extraction lengths have been determined in consideration of performance tests and actual installations.



4. SHAPE, DIMENSIONS, AND DIMENSIONAL TOLERANCES In relation to the performance-based modification of the Standard, the imposing of requirements for pipe shape and dimensions have been restricted to the minimum, while fundamental design and installation-related aspects such as internal diameter, thickness, and effective length, are specified accordingly.



In consideration of pipe-end face protection and stress distribution of the jacking force, the use of cushion material is also specified.



4.1



Joint Structure This is a newly introduced section to the Standard. Joint structure shall be of such design that is confirmed under the Joint Model Test Regulation. The detailed shape, dimensions, and dimensional tolerances of the joint shall be in accordance with the approved design of the pipes.



Changes to joint designs that are already established shall be subjected to the approval of Japan Sewerage Works Association.



“Additional fabrication that will not affect the shape or strength of the pipes” refers to the provision of bevels at the edge of the pipe (for safer demoulding work), and guide-grooves for proper positioning of gaskets.



4.2



Standard Pipe The most commonly used jacking pipe is referred to in this Standard. The shape, dimensions, and dimensional tolerances are as given in Figure 1. Pipe ends are described as socket and spigot, with the socket having the pre-embedded steel collar design.



18



Requirements are specified for 4 dimensions; namely, Internal Diameter (D), Thickness (T), Effective Length (L), and Joint Minimum Thickness (t). Internal diameter, thickness, and effective length are basic dimensions, and tolerances have been assigned to each. Joint minimum thickness is specified in order to calculate the axial loading capacity from the effective section area, based on such standardized dimension.



Pre-embedded locking sockets are included in the notes, as in previous revisions. Shape, dimensions, and locations of this item is further detailed in Reference Document No. 6.



4.3



Intermediate Pipes The Type-S and Type-T Intermediate Pipes compose the set of Intermediate Jacking Pipes, which is used to thrust the pipes installed ahead of it with the expansion-and-contraction action of hydraulic jacks. The length of the combined Type-S and Type-T Intermediate Pipes is designed such that it does not exceed the length of the Standard Pipe when the stroke of the jacks is at maximum. This is necessary since the joint between the Type-S and Type-T Intermediate Pipes does not accommodate deflections, and will impede the jacking process if the length is longer than the Standard Pipe.



Moreover, the length of the collar for the Type-S Intermediate Pipe needs to be of a length that will not allow dislocation from the gasket of the Type-T Intermediate Pipe when the jacks are fully extended. It is also necessary that the Type-T Intermediate Pipe has an extra margin of shaft length to cover the slack length when the jacks and the Support Ring are removed at the final stage of the intermediate jacking process.



From considerations described above, requirements for Type-S Intermediate Pipes are specified for 4 dimensions; namely, Pipe Internal Diameter (D), Collar Internal Diameter (Dc), Length (Lc), and Thickness (tc). Requirements for Type-T Intermediate Pipes are specified for 4 dimensions; namely, Pipe Internal Diameter (D), Shaft External Diameter (D1), Shell Thickness (t2), and Effective Length (LT).



In relation to the setting of these dimensions, the capacities of the jacks and their dimensions, and the thickness of the Support Rings are as given in Table 4. The arrangement is as shown in Figure 8.

In order to minimize the friction occurring at the gaskets during the sliding movements, lubricant inlets are provided at 4 locations along the circumference of the Type-T Intermediate Pipe.



The Internal Diameter of Type-S Intermediate Pipe is designed to be slightly larger than the Internal Diameter of the Standard Pipe. This portion is filled with in-situ mortar at the end of the jacking installation.



4.4



Grouting Socket Formerly, Grouting Sockets have been specified in detail for material, shape and dimensions. A broader specification for socket and plug is made in this revision.



Quality and designation requirements of socket and plug are unchanged from previous versions. The use of alternatives that have the same or higher functional properties has been allowed in this revision. 20



4.5



Joint Groove Formerly, Joint Groove has been specified in detail for dimensions. This revision has been revised to specify only the requirement for shape.



4.6

The use of alternatives that have the same or higher functional properties has been allowed in this revision.



5. MATERIALS 5.1



Cement There are no revisions in this Section.



5.2



Aggregates The requirement to conform to Appendix 1 of JIS A 5308 has been added. In the case of employing aggregates evaluated as “Category B” under the requirements in Appendix 1 of JIS A 5308, corrective measures against alkali-aggregate reactivity shall be taken in accordance with requirements given in Sections 3, 4, and 5 of Appendix 6.



5.3



Water The requirement to conform to Appendix 9 of JIS A 5308 has been added.

5.6



Steel Materials There are no revisions in this Section.



21



5.7



Gaskets There are no revisions in this Section. In the case of using rubber gaskets, it shall conform to JIS K 6353; Class IV for Standard Pipes, and Class I - A60 for Intermediate Pipes (in consideration for additional friction).



6. MANUFACTURE 6.1



Measurement of Materials There are no revisions in this Section.



6.2



Chlorides Content In consistency with other standards, Chloride ions (Cl―) present in fresh concrete shall not be higher than 0.30kg.m3.



6.3



Steel Collar No change has been made in this Section. However, the reference to the provision of an anchor mechanism to the embedded item has been made in consideration of the various forms of anchors being developed.



6.4



Forming There are no revisions in this Section.



6.5



Curing This Section has been modified, with the deletion of the reference to high-temperature and moisture requirement after demoulding (in the case of using expansive admixtures). The commonly used method of steam curing is as follows: (1)



Placing of pipe in curing chamber while still in mould.



(2)



Steam curing to be started after a minimum of 2 hours from the time of concrete mixing.



(3)



Temperature elevation to be not higher than at the rate of 20 degrees Centigrade per hour, with the maximum temperature of around 65 to 75 degrees Centigrade.



(4)



Mould to be removed from the curing chamber only after the temperature is close to ambient temperature.



6.6



Gaskets There are no revisions in this Section.



6.7



Intermediate Pipes There are no revisions in this Section.



22



7. TESTING METHODS 7.1



External Loading Test There are no revisions in this Section. Supports used for this test shall be straight timber or composite-wood material (eg. plywood) that are sufficiently rigid to bear the test loads. Rubber pads shall be of sufficient hardness (about Hs = 60).



With respect to the loading until cracking load, this may be conducted at any suitable rate up to half of the specified load. For the second half, uniform loading at the rate of 10kN/m per minute shall be applied. In order to estimate the timing of the occurrence of cracks, the use of dial gauges to observe the deformation of the pipe accompanying the applied loads is recommended.



7.2



Compressive Strength Test of Concrete Compressive strength test of concrete shall be carried out with solid cylindrical specimens prepared in accordance with JIS A 1132. The previous reference to the testing in accordance with JIS A 1136 (Method of Test for Compressive Strength of Spun Concrete) has been deleted.



In relation to the various jacking methods, the axial bearing capacity of the pipe is very important. However, since it is not possible to directly verify this using the product itself, this is checked indirectly with the solid cylindrical specimens. There is sufficient correlation between the concrete of the pipe body and the specimen, and although the specimen is used for control purposes, it is necessary to confirm this correlation by testing both the specimen and the pipe.



7.3



Water-tightness Test Water-tightness test shall be carried out on the joint of 2 pipes fully attached, with 0mm extraction length. Water is introduced to the external or internal line of the joint, and water pressure is applied in accordance with the joint specification requirement. Joint performances required are 0.1MPa for “JA”, and 0.2MPa for “JB” and “JC”. It is necessary to note that since the pipes are not normally subjected to full flow in the case of sewerage pipelines, the design is made primarily in consideration of the external water pressure during and after installation of the pipeline. In this respect, the test with the application of water pressure at the external line of the joint is more appropriate. However, since there has been no problems reported with pipes installed which have been tested at the internal line of the joint, the two test methods are both approved for the time being. In the future, only the external test may be specified as the requirement.



23



8. INSPECTION METHOD The requirements in this Section applies only to the inspection of quality, shape, and dimensions of the pipe during the manufacturing process. With respect to inspection at delivery, the requirements may be agreed among the concerned parties in addition to or separate from those that have been established by this Association.



8.1



Inspection Items There are no revisions in this Section.



8.2



Appearance and Shape There are no revisions in this Section. “Detrimental flaws” mentioned in Section 3.1 refers to conditions given below: For pipe body; (1)



Cracks in pipe body. However, very thin surface cracks related to drying shrinkage are permissible.



(2)



Damage to 3% or more of pipe end surface.



(3)



Cavity or aggregates exposure to 5% or more of pipe external surface.



(4)



Surface stains caused by reinforcement.



For steel collar: (5)



Deformations that may adversely affect the water-tightness of the joint.



In addition, “smooth” shall refer to the absence of: exposed coarse aggregates, any voids due to dislodged coarse aggregate, and excessively rough finished surfaces.



8.3



Dimensions There are no revisions in this Section. For the measurement of internal diameter and thickness of the pipe, these shall be inspected on both ends of the pipe at the four points made by the right-angled intersection of 2 random lines placed at the ends of the pipe. Effective length of the pipe shall be measured at the left and right sides of the internal surface.



Thickness (T) shall be measured using calipers at about 150 to 200mm from the edge of the pipe.



Inspection shall be made for 1 pipe randomly selected from 1 lot of pipes, for each size. The quantity of pipes per 1 lot shall be as given in Table 5. If the inspection does not result in a pass, the entire quantity shall be inspected, and each pipe shall be passed individually in accordance with the requirements.



24



Since D, T, and L are critical dimensions, these are recommended to be inspected for each pipe at demoulding, with the use of limit gauges. Intermediate Pipes are generally inspected for all quantity.

External Strength As required in previous versions, external strength is inspected only for cracking strength. Breaking strength test is not conducted owing to the following reasons, but whenever there is a change in the design specifications, this test is necessary to confirm the performance of the pipe. (1)



Breaking strength is determined by the reinforcement design, which can be verified during the manufacturing process control.



(2)



Previous test results confirm that pipes which pass the cracking strength test also pass the breaking strength test.



Inspection shall be made for 1 pipe randomly selected from 1 lot of pipes, for each size, and Class 1-50, Class 1-70, and Class 2-50. The quantity of pipes per 1 lot shall be as given in Table 5. This “quantity of pipes per 1 lot” refers to the situation of the pipes being produced consecutively, and therefore the frequency of the test will have to be determined in consideration of the actual production situation.



For Type-T Intermediate Pipe, the inspection is generally carried out for Class 1 and Class 2 as separate lots, for sizes ranging from 1000 to 3000mm. The size of each lot is about 20 pieces.



8.5



Concrete Compressive Strength There are no revisions in this Section. “Specimens representing the specified lot of pipes” shall refer to samples collected at least once daily, per concrete mix design. Tests are carried out for the specified age in accordance with Section 7.2, and shall be passed if the specified strength is satisfied. “Specified age” shall refer to the age of the concrete as established under the quality control program, and “specified strength” shall refer to the compressive strength as established under the same quality control program.



25



In consideration of the difficulty in maintaining large quantities of specimens for repeated testing, requirements for re-inspection is specified so that core samples may be extracted from the pipe body for compressive strength tests.



8.6



Water-Tightness of Joint The water-tightness of the joint is guaranteed if the shape and dimensions are in accordance with the specification. This test is conducted for each size-group of pipes as one lot, produced within a specified period, and which have the same dimension (and tolerance) of opening between the socket and spigot diameters.



This size-group of pipes and the frequency of the test required are normally as given in Table 6.

Appendix 1



Joint Model Test Regulation 1. SCOPE This Regulation specifies the requirements for the tests to be conducted to verify the water-tightness of the joint of Jacking Reinforced Concrete Pipes for Sewerage that are manufactured in accordance with JSWAS A-2 (hereafter “A-2”).



2. TEST ITEM 2.1



Test Pipe In principle, the test shall be conducted with 2 pipes of the size from the smallest of the size-group. However, if there are numerous types of the same size, the test shall be carried out for the smallest pipe size of each type.



The joint of the pipes to be tested shall be that combined part of the socket and spigot where the gasket shall be subjected to its minimum compression.



The length of the pipes shall be in accordance with the requirement for testing, and a cushion material (ring) of 10mm shall be attached.



As necessary, insofar as the joint design is not affected, modification work may be performed on the pipes to accommodate the test apparatus.



2.2



Gasket The gasket shall be of such height that it will be at its minimum compression rate when the pipes are jointed.



2.3



Measuring of Dimensions The measuring of dimensions for the pipes and gaskets shall be conducted before the test.



2.4



Quality The quality of the pipes and the gasket shall satisfy the requirements as given in A-2.



2.5



Installation of Gasket The gasket shall be fitted securely to the pipe prior to the testing of the pipe joint.



27



3. TEST METHOD 3.1



Test Apparatus Equipments and apparatus for the test shall be designed so as not to cause any adverse effects to the joint performance.



3.2



Test Method The test to confirm the water-tightness of the joint shall be conducted in accordance with the categorization as given in Table 7. The 2 connected pipes shall be subjected to horizontal test, bending test, and horizontal-bending combination tests (hereafter “combination test”) with the apparatus designed to exert water pressure at the external line of the joint. Each specified water pressure is maintained for 3 minutes. The jointed pipes may be positioned either vertically or horizontally.



Examples of the water-tightness test method are as shown in Figures 9 to 11. An example of the water-tightness test apparatus is as shown in Figure 12.

3.4



Test Procedure The water-tightness test is conducted with the same pair of test pipes, in the sequence of horizontal, bending, and combination tests. Confirmation of the test water pressure and test extraction lengths shall be made after checking for leakages in accordance with the A-2 requirements.



3.5



Verification of Test Pipes and Test Conditions Validation by the Japan Sewerage Works Association requires the verification of the quality and dimensions of the test pipes by Test Result Report, and verification by actual observation of the water-tightness tests.



4. ACCEPTANCE CRITERIA The joint performance of the test pipes shall be judged to be in conformance and accepted as satisfying the required performance under A-2 if the test is conducted in accordance with Sections 2 and 3, and no leakage from the joint is observed.



5. REJECTION CASE In the event that the test results in a rejection, re-testing is not acceptable in principle for the same joint design and gasket for the same category.



31



Appendix 1



Joint Model Test Regulations Commentaries This regulation is established for the conducting of tests to verify the acceptability of the various joint performance of reinforced concrete pipe as required under the A-2 specification.



1.



SCOPE The tests established herein are for the confirmation of the performance of joints, and are collectively categorized in the quality control scheme as water-tightness tests for joints.



2. TEST ITEM 2.1



Test Pipe; 2.2 Gaskets Rubber rings are most commonly used. On this basis, the water-tightness of the joint is largely influenced by the compression rate of the rubber ring. When the compression rate of the rubber ring is at its minimum, the water-tightness of the joint is lowest. Therefore, the dimensions of the test pipe joint is established such that the compression rate is to be at its minimum within the tolerances.



Accordingly, the height of the rubber ring is established so as to provide the minimum compression rate when jointed.



In view of the difficulty in arranging the test pipe and gasket so as to precisely obtain the limit condition within the tolerances, it is permissible to adopt the average value of the joint dimension, and to obtain the minimum compression rate with the estimated height of the rubber ring.



In addition, since the deflection angle is larger for smaller nominal diameter of the pipe under the condition of fixed extraction length, the smallest size of pipe for the size-group is adopted for the tests.



Lastly, modification work to the pipe that will not influence the performance of the joint; such as the installation of inserts near the joint location, is permitted to accommodate the efficient conducting of the various tests.



32



2.3



Measuring of Dimensions The measuring of dimensions for the pipe joint and gaskets shall be conducted before the test. This is necessary as it will not be possible to measure the gasket-seat dimension of the pipe afterwards, and since it is common to use adhesives for the attachment of gaskets.



2.4 Quality As stated.



2.5 Installation of Gasket In order to provide the proper water-tightness of the joint, the gasket should naturally be attached at the specified location, and should not shift when the pipes are jointed. As it is common to use adhesives to attach the gasket to the spigot or to the collar, this should be carried out in a timely manner before the jointing of pipes for the tests.



3. TEST METHOD 3.1



Test Apparatus Equipments and apparatus shall be designed so that they will reliably confirm the performance of the test pipe. Additional attention shall be given to the fact that they should withstand the movement of the test pipes; and at the same time to not cause adverse influence, when the pipes are arranged for bending and extraction at the joints.



3.2



Test Method Three tests; namely, horizontal, bending and combination tests, are established to confirm the water-tightness of the joint.



The 3-minutes holding period for the water pressure is applicable regardless of the material of the gasket. For example, this shall also apply in the case of water-expansive rubber rings. The requirements for the performance of the joint under A-2 are extraction length and water pressure resistance. Table 7 is established to satisfy such requirements. It should be noted that 0.05MPa has been added to the required pressure for horizontal and bending tests, which are the arrangement inferred for a normal-condition, and the values shown for the combination test are for the situation under a level-2 earthquake condition.



Regarding extraction lengths, the specified value applies for the horizontal test, and the specified value is multiplied by 1.5 for the bending test, in consideration of installation-time errors.



33



For the combination test, the additional required extraction length is derived by considering the factor of 1.5% to the length of the Standard Pipe as permanent strain in the soil under earthquake situation ( 2430mm x 0.015 = 37mm).



3.3



Measurement of Test Extraction Length Required extraction length as specified in A-2 is the dimension at the external side of the joint. Since it is not possible to directly measure this during the test, the guideline in this section is provided to determine this dimension by measuring first the internal side of the joint.



3.4



Test Procedure The 3 tests are to be conducted with the same pair of test pipes in view to verifying the condition of the attachment of the gasket at the joint under deflection situations.



4



ACCEPTANCE CRITERIA Attention is drawn to the strict conformance to this Standard whereby the test result is acceptable by observation for leakages at the joint.



5



REJECTION CASE In the event that the tests result in a rejection despite the conducting of the test with test components in conformance with the specified qualities, the joint design is judged to be defective, and a re-test is not acceptable in principle.



This course of action is reasonable in view of the expectation that numerous prior tests would already have been conducted in the course of developing such joint design.



However, a re-test is permissible in the case that the Japan Sewerage Works Association is in agreement that the source of the failure is not attributed to the joint design.
