Introduction

According to the application field of the pipeline system to be repaired, the trenchless repair technology is divided into the following technology series:

---Plastic pipe system for trenchless repair of underground non-pressure drainage network;

--- Plastic pipe systems for trenchless repair of underground pressure drainage networks;

---Plastic pipe systems for trenchless repair of underground water supply networks;

---Plastic piping system for trenchless repair of underground gas pipeline network:

GB/T 43982 "Plastic Pipe Systems for Trenchless Repair of Underground Water Supply Pipe Networks" specifies the plastic pipe systems for trenchless repair of underground water supply pipe networks:

Requirements for pipelines: GB/T 43982 is intended to consist of the following parts:

--- Part 1: General: The purpose is to establish the requirements for plastic pipe systems used for trenchless repair of underground non-pressure drainage networks:

General requirements, overarching principles and relevant rules to be followed:

--- Part 2: Continuous interlaced lining method: The purpose is to clarify the applicable materials of the continuous interlaced lining method in production, manufacturing and construction inspection:

Technical requirements for the collection phase:

--- Part 3: Tight fit lining method: The purpose is to clarify the applicable materials of the tight fit lining method in production, manufacturing and construction inspection:

Technical requirements for the collection phase:

--- Part 4: In-situ curing lining method: The purpose is to clarify the applicable materials of the in-situ curing lining method in production, manufacturing and construction Technical requirements for the collection phase:

Part 1 (General Principles) of each technical series specifies the general requirements for non-excavation repair technology in this field, and the other parts correspond to specific Engineering technology methods (construction methods): Each part (construction method) is used in conjunction with Part 1 (General Principles): This document is used as Part 1 of GB/T 43982 the:2011 Standard specifies general requirements for plastic pipe systems used in the rehabilitation of water supply networks: Since not all technologies (processes) are applicable to every application, Therefore, the components contained in different technical series standards may vary: For further information, see GB/T 37862:

The standard system table in Figure 1 shows the common parts of the non-excavation repair technology system, the relationship between each technology series and its basic constitute:
