Foreword

This document is in accordance with the provisions of GB/T 1:1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules for Standardization Documents" drafting: This document replaces GB/T 11836-2009 "Concrete and Reinforced Concrete Drainage Pipes": In addition to structural adjustments and editorial changes, the main technical changes are as follows:

a) The range of product specifications in Table 2 has been changed, the nominal inner diameter has been increased to 4000mm, the minimum design wall thickness of all levels of pipes has been unified, and The external pressure load inspection index of some pipes has been changed (see Table 2, Table 2 of the:2009 edition);

b) The D-type type of steel socket pipe with flexible interface is added (see 4:1:4);

c) Added requirements for interface sealing materials (see 5:1:8);

d) The material requirements for backing plates are added (see 5:1:9);

e) Increased concrete mix design, impermeability and quality control requirements (see 5:2);

f) Added the requirements for dimensional deviation in the manufacture of reinforcement skeletons (see 5:3:8);

g) The requirements for the manufacture of steel sockets have been added (see 5:4);

h) Added requirements for the manufacture of embedded parts (see 5:5);

i) Added pipe fabrication requirements (see 5:6);

j) Added anti-corrosion requirements for steel parts and pipes (see 5:7);

k) Added the requirements on the compression rate and circumference of the rubber sealing ring (see 5:8);

l) The requirements for the concrete strength grade have been changed, and the requirements for the compressive strength of the concrete at the time of delivery have been added (see 6:1, 6:1 of the:2009 edition);

m) Added requirements for water absorption of pipe concrete (see 6:7);

1 Scope

GB/T 11836-2023 is the Chinese national standard on 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 17 March 2023 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 October 2023. 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 document specifies the classification and marking of concrete and reinforced concrete drainage pipes (hereinafter referred to as pipes), general provisions, technical requirements, test Inspection methods, inspection rules, signs, transportation and storage, and product certificates: This document applies to pipes used for gravity flow pipelines such as rainwater, sewage, water diversion and farmland drainage and irrigation: Production of other purposes (such as comprehensive pipe gallery, floor Pipelines, pipelines, tunnels, etc:) can be implemented with reference to this document: This document is applicable to pipes used in construction methods such as grooving and jacking:
