The high-strength concrete pipe core with the steel cylinder is wound with prestressed wires, a cement mortar protective layer is sprayed, a steel bell and spigot is adopted and welded together with the steel cylinder, a groove and a rubber ring of the bell and spigot form a flexible joint of a sliding rubber ring, the steel pipe core is a composite structure formed by steel plates, concrete, the high-strength steel wires and the cement mortar, and the steel pipe core has the characteristics of steel and concrete. According to the position of the steel cylinder in the tube core, the method can be divided into two types: a lining type Prestressed Concrete Cylinder Pipe (PCCPI) and an embedded Prestressed Concrete Cylinder Pipe (PCCPE). The prestressed steel cylinder concrete pipe has the characteristics of reasonable composite structure, high internal and external pressure bearing capacity, good joint sealing performance, strong shock resistance, convenient and quick construction, good corrosion resistance, convenient maintenance and the like, is concerned by engineering industries, and is widely applied to long-distance water delivery main lines, pressure inverted siphons, urban water supply engineering, industrial pressure water delivery pipelines, power plant circulating water engineering sewer pipes, pressure sewage discharge main pipes and the like. Compared with the prior pipe, the PCCP has the advantages of wide application range, long economic life, good anti-seismic performance, convenient installation, low operation cost, no water leakage and the like.

The steel wire of the prestressed wire winding machine for the PCCP water pipeline is pulled by a wire guide trolley, namely, the prestressed wire winding machine runs in a mode of chain traction fastened on the wire guide trolley. Meanwhile, the PCCP water conveying pipeline rotates, so that the wire winding of the PCCP water conveying pipeline is realized.

Due to the characteristics of the PCCPL pipe, the steel lining barrel is inevitably rusted after the PCCPL pipe is poured and molded and is stored outside during maintenance, time and labor are wasted when the PCCPL pipe is manually polished, and the efficiency is low.

And rust iron chips and metal dust are easily produced in the polishing process, and if the rust iron chips and the metal dust are sucked by polishing personnel, the health of the polishing personnel is not facilitated.
