T/SCJC P03-2022 Pre-stressed steel-concrete pipe jacking

Scope

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 pipeline operation. Pre-stressed steel cylinder concrete pipes using the pipe jacking construction method are also covered. When manufacturing pipes outside the scope specified in this standard, reference may 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 conveyance pipelines, farmland irrigation, factory pipe networks, power plant supplementary water pipes and cooling water circulation systems, pressure tunnel pipelines, inverted siphons, crossing culvert pipes, and integrated pipe galleries, etc., in clay, silty soil, sandy gravel soil, and medium-soft rock strata.
