Preface
This standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 15345-2003 "concrete water pipe test method".
This standard compared with GB/T 15345-2003, the main changes are as follows.
--- to expand the scope of application of the standard, an increase of unbonded prestressed concrete pipe, jacking construction method with steel tube concrete pipe (see paragraph 1
Chapter, chapter 1 of the.2003 edition);
- Revised some normative references (see Chapter 2, Chapter 2 of the.2003 edition);
- to add, modify, and delete some of the terms and definitions (see Chapter 3, Chapter 3 of the.2003 edition);
- "Test instruments and gauges" and the normative appendix "Major instruments and gauges for testing" (see chapter 4 of the.2003 edition and
Appendix A);
- Additional requirements for instrumentation and test equipment are added to each project test method (see Chapter 4, Chapter 5, paragraph
Chapter 6, Chapter 8, Chapter 11);
- modified part of the geometry of the test method (see Chapter 5,.2003 version of Chapter 6);
- Added "PCCP, JCCP Outside Pressure Load Test Method (Three Point Test Method)" and as a normative appendix (see Chapter 7 and attached
Recorded B);
- Modification of the data Appendix "Protective mortar compressive strength test method (cutting method)" for the normative appendix (see Chapter 9 and Appendix
C,.2003 version 11.4 and appendix C);
--- Removal of protective layer mortar water absorption test methods and information Appendix "PCCP protective layer mortar water absorption test method (pressure
(See Chapter 12 and Appendix D of the.2003 edition);
--- the "protective layer mortar water absorption" to "protective layer mortar water absorption," modified the data Appendix "protective layer mortar water absorption test
(As described in Chapter 10 and Appendix D, Edition.2003), and as a normative appendix (see Chapter 10 and Appendix D, Edition.2003)
And Annex E);
--- Removal of "mortar strength of protective layer" Test method and normative appendix "Manufacture and maintenance of protective mortar test piece" (see Edition.2003
11.1, 11.2, 11.3 and appendix B);
- modified and increased the test method for the control of the rotation angle of the double-fold PCCP by the tube end displacement value or the joint clearance difference (see 11.4,.2003
Version of the 13.5);
--- Added information on the "PCCP, JCCP and UPCP hydraulic test devices" (see Appendix A).
