Scope

Scope: This standard specifies the terms and definitions, product classification, raw materials, technical requirements, test methods, inspection rules, marking, packaging, transportation and storage, factory certificates, etc. for inorganic ultra-high performance concrete pipe jacking pipes and excavation drainage pipes. This standard applies to inorganic ultra-high performance concrete pipe jacking pipes and excavation drainage pipes formed by centrifugal casting, suspension roller casting, core mold vibration, vertical extrusion, and other methods. This standard applies to pipes used for rainwater, sewage, water diversion, and farmland irrigation with a pressure of not more than 0.2 MPa, and also applies to pipes for conveying generally corrosive media. The production of inorganic ultra-high performance concrete pipe jacking pipes and excavation drainage pipes for other purposes can refer to this standard for implementation. The pipes produced in accordance with this standard are suitable for trench construction, pipe jacking construction, and other construction methods. Main technical contents: performance of inorganic ultra-high performance concrete materials, appearance quality, allowable deviations in dimensions, internal water pressure, external pressure load, and thickness of protective layer.
