T/SCJC P03-2025 Jacking construction of prestressed concrete cylinder pipe
Basic Information
Scope
This standard specifies the terms and definitions, classification, raw materials, technical requirements, test methods, inspection rules, marking, transportation and storage, usage regulations, and factory certificates for pre-stressed steel cylinder concrete pipe jacking products. This standard applies to the manufacture of pre-stressed steel cylinder concrete pipe jacking products with a nominal inner diameter of 800 mm to 4000 mm, and a working pressure or static water head of no more than 2.0 MPa in pipelines. Pre-stressed steel cylinder concrete pipes using the pipe jacking construction method are also covered. When manufacturing pipes outside the specified range of this standard, reference can be made to this standard for implementation. Pipes manufactured in accordance with this standard are suitable for use in urban water supply and drainage pipelines, industrial water supply pipelines, farmland irrigation, factory pipe networks, power plant feedwater pipes and cooling water circulation systems, pressure tunnel pipelines, reverse siphons, crossing culvert pipes, and comprehensive pipe galleries, among other projects, in clay, silt, sandy gravel soil, and medium-soft rock strata. 6.
