排水用离心玻璃钢夹砂管最新规程关键技术解读

Interpretation of Key Technologies in Technical Specification for Centrifugal Casting Glass Fiber Reinforced Plastics Mortar Pipes of Underground Drainage Pipeline Engineering

中国工程建设标准化协会发布的《离心浇铸玻璃纤维增强塑料夹砂管排水埋地管道工程技术规程》(T/CESS 1130—2022,以下简称《规程》)已于2023年1月1日起施行。《规程》从管材、设计、施工、功能性试验、验收等方面做出规定,对保证管材生产质量、规范工程设计、提升管道工程质量具有重要意义。对《规程》中的关键技术进行了详细解读,包括管道防腐及耐久的要求、管材环刚度、接口方式及适用条件、结构计算、检查井连接方式、顶管及内衬管施工要求和自密实回填材料七个部分。该技术解读有助于对《规程》的推广及应用。

The Technical Specification for Centrifugal Casting Glass Fiber Reinforced Plastics Mortar Pipes of Underground Drainage Pipeline Engineering(T/CECS 1130-2022,Hereinafter referred to as the Specification),jointly issued by the China Association for Engineering Construction Standardization(CECS),has been implemented on January 1,2023.The Specification covers provisions relating to pipe material,design,construction,functional test,acceptance and other aspects to ensure the quality of pipe production,standardize engineering design,and enhance the quality of pipeline engineering,which is of great significance.This paper analyzes the main characteristics of the Specification,including seven parts:requirements for corrosion resistance and durability of pipes,the mode and application conditions of joint,ring‑stiffness of pipe,structural calculations,connection modes of manholes,construction requirements for pipe jacking and lining,and self‑compacting backfill materials.These aspects contribute to the promotion and application of the Specification,aiming to improve pipeline engineering practices.
