1. a levigate metallurgical slag and levigate quartz sand and flyash three components are mixed the production technology of high-strength pipe pile again, ground slag or slag, levigate quartz sand and flyash are stirred into compound with cement, sand, rubble, concrete high efficiency water reducing agent, water in forced concrete mixer, then compound is fed in the female die of the pile tube punching block of having cleaned out and placed deformed bar, the upper mold section post-stretching deformed bar of pile tube punching block closes, this punching block is placed on carries out centrifugal operation on the centrifuge, carry out atmospheric steam curing behind the centrifugal operation;

  • Carry out prestressing force behind the atmospheric steam curing and put and open and the pile tube stripping operation, simultaneously the pile tube after the demoulding is carried out autoclave curing, product can dispatch from the factory when the concrete strength of pile tube reached design grade after the autoclave curing.
