T/SHJX 064-2024 Plumbing Pipe Fitting Application Technical Specification for Embedded Socket Connection Components

Scope

Main technical content: This standard document was drafted in accordance with the provisions of GB/T 1.1—2020, "Guidelines for Standardization Work—Part 1: Structure and Drafting Rules for Standardization Documents". The embedded socket-type connection pipe technology reduces potential construction errors and improves the quality of formed tunnels; it effectively enhances the lateral stiffness of the lining and features the characteristics of "ring stiffness and longitudinal flexibility", which can effectively improve the pipe's resistance to deformation and settlement. It not only improves the construction quality of shield tunnels and reduces the cost of later-stage operation and maintenance, but also meets the needs of mechanized and automated assembly and will play a positive role in promoting and guiding the application of automated construction technologies in China's rail transit field. To better guide, promote, and standardize the application and development of embedded socket-type connection pipe technology in urban rail transit projects, this document was developed based on scientific research results and practical engineering experience. During the preparation process, the drafting team conducted in-depth investigations and studies, carefully summarized the practical experience of domestic actual projects, and solicited opinions from various parties before finalizing the document through review. Given that the application of embedded socket-type connection pipe technology in China is still in its infancy, this document will continue to be refined through practical application. During the trial implementation, any suggestions or opinions are welcome and should be sent to the drafting unit. This standard document specifies the design of embedded socket-type connection pipe for shield tunnels, the inspection of connection pieces, the production of embedded socket-type connection pipes, and the construction and acceptance of shield tunnels with embedded socke
