GB/T 16752-2017Test methods of concrete and reinforced concrete sewer pipes (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 16752-2006 "concrete and reinforced concrete drainage pipe test method." This standard and GB/T 16752- 2006, the main technical changes except for editorial changes are as follows:

--- Increasing the steel pipe width and thickness of the mouth detection (see 6.3.6).

--- Increasing the box culvert length, width, height and other items of testing (see 6.3.9)

--- Increased anti-corrosion coating of steel testing the relevant provisions (see Chapter 7).

--- Increased large-diameter pipe hydrostatic test method (see 8.3,9.3).

--- Increasing the joint corner sealing performance of the project test methods (see Chapter 9).

--- Increased shaped tube pressure load test shows (see Appendix C). This standard proposed by the China Building Materials Federation. This standard by the National Standardization Technical Committee cement (SAC/TC197) centralized. The main drafting units of this standard.

1 Scope

GB/T 16752-2017 is the Chinese national standard on test methods of concrete and reinforced concrete sewer pipes, in the field of construction materials and building. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 14 October 2017 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 September 2018. Classification: ICS 91.100.30, CCS Q14. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the terms and definitions of concrete and reinforced concrete drainage pipe test methods, as well as the appearance of quality, size deviation, steel Test of anti-corrosion coating of socket steel plate, inner water pressure, sealing performance of corner joint, external pressure load, thickness of protective layer and concrete strength Methods, and the repair of the test data and comparison methods and test reports. This standard applies to the use of various types of production of various types of concrete and reinforced concrete drainage. Other prefabricated components can refer to carried out.

3 Terms and definitions

The following terms and definitions apply to this document.

3.1 Sticky stick The outer surface of the pipe wall due to cement mortar mold adhesion formed by rough is not smooth.

3.2 Ma surface scale Tube concrete surface appears more dense holes.

Note. Due to the immediate mold release vibration generated by the core mode surface and micro-pores do not belong to the Ma surface.

3.3 Honeycomb honeycomb Tube concrete surface due to the lack of cement mortar and the formation of pebbles exposed and hollow.
