High strength anti-cracking large-diameter pipe pile manufacturing die, material and manufacturing technology

Abstract

The invention discloses a high strength anti-cracking large-diameterpipe pile manufacturing die, material and manufacturing technology. The high strength anti-cracking large-diameter pipe pile manufacturing die comprises a die base, a lower die supporting seat fixedly mounted on the die base and an upper die supporting seat fixedly connected to a lower die; a semi-circular sliding slot is formed in the lower die supporting seat, a side core-pulling device is arranged in the semi-circular sliding slot, and a through hole is formed in the lower part of the side core-pulling device; the through hole is connected with a steam machine through an air pipe; a rolling carrier roller is arranged on the inner wall side of the side core-pulling device, a plurality of rolling wheels sleeve the rollingcarrier roller, and one end of the rolling carrier roller is connected with a driving motor through a driving belt. According to the high strength anti-cracking large-diameter pipe pile manufacturingdie, material and manufacturing technology, an integrated die of centrifugal forming and steaming is adopted to manufacturea pipe pile so as to avoid the collision and appearance of crack gaps of thepipe pile in the process of consigning in a workshop, the resistance and strength of the pipe pile in practical use are enhanced, and meanwhile, the working procedure and labor quantity of workers are saved.

Description

technical field [0001] The invention belongs to the field of pipe pile preparation equipment, in particular to a high-strength anti-crack large-diameter pipe pile production mold, material and production process. Background technique [0002] After the existing prestressed pipe piles are filled with concrete, they need to be put into a special centrifugal tank for centrifugal forming to make the filled concrete compact, and then the formed pipe piles are transported to a special steaming chamber by a truss crane. The curing pond is reinforced by steaming. During the handling process, the centrifugally formed pipe piles are easily collided in the workshop. The concrete that has not been steamed has no hydration reaction, and the degree of condensation is not high, so that the centrifugally formed pipe pile wall Cracks are prone to occur, which affects the high strength of the pipe pile in actual use. [0003] For large-diameter pipe piles, the process of grouting, centrifuga...

AI Technical Summary

Problems solved by technology

[0002] After the existing prestressed pipe piles are filled with concrete, they need to be put into a special centrifugal tank for centrifugal forming to make the filled concrete compact, and then the formed pipe piles are transported to a special steaming chamber by a truss crane. The curing pond is reinforced by steaming. During the handling process, the centrifugally formed pipe piles are easily collided in the workshop. The concrete that has not been steamed has no hydration reaction, and the degree of condensation is not high, so that the centrifugally formed pipe pile wall Very prone to cracks, affecting the high strength of pipe piles in actual use

[0003] For large-diameter pipe piles, the process of grouting, centrifugation, oxygen evaporation and transportation is more troublesome than ordinary pipe piles. If the production problems of large-diameter pipe piles are solved, the technicians have not given a solution so far.
