Introduction

GB/T 37862 specifies the technical classification, terms and definitions of plastic piping systems for trenchless repair. This document specifies that underground Requirements for plastic piping systems for trenchless repair of pressurized drainage networks. According to the application field of the repaired pipeline system, the trenchless repair technology is also Divided into the following technical series, corresponding to different series of standards. ---Plastic pipe system for trenchless repair of underground pressureless drainage pipe network (this series of standards); ---Plastic pipe system for trenchless repair of underground pressurized drainage pipe network (not yet prepared); --- Plastic pipe system for trenchless repair of underground water supply network (not yet prepared); --- Plastic piping system for trenchless repair of underground gas pipe network (not yet prepared). GB/T 41666 "Plastic Pipeline System for Trenchless Repair of Underground Unpressurized Drainage Pipe Network" is proposed to consist of the following parts. --- Part 1.General; --- Part 2.Coiled tube lining method; --- Part 3.Closely fit lining method; --- Part 4.In-situ curing lining method; --- Part 5.Short tube insertion method; --- Part 7.Spiral winding lining method; --- Part 8.Segment lining method; --- Part 9.Padding method; --- Part 10.Spray polymer lining method. Part 1 (General) of each technology series specifies the general requirements for trenchless repair technology in this field, and the other parts are specific engineering. Engineering method (construction method). Each part (Construction Method) and Part 1 (General) shall be used in combination. This document specifies the phases of the close fit lining method off requirements. See GB/T 37862 for further information. Since not all technical (construction method) standards are applicable to all application fields, The components contained in this different technical series of standards will vary. The standard system table in Figure 1 shows the general parts of the trenchless repair technology system, the interrelationship of each technology series and its basic constitute.
