Abstract

The invention belongs to the technical field of concrete pile production, and in particular relates to a production process of centrifugal slurry-free piles, a supporting material introduction mold and a vibrating distribution vehicle; the production process of centrifugal slurry-free piles includes the following production steps: step A, preparing materials and Compile the reinforcement cage and assemble it into shape; step B, prepare dry hard concrete material; step C, hang the bottom mold of the production mold on the vibrating distribution vehicle, and use the lead mold to distribute the material: step D, combine the cover mold of the production mold with the Clamp the bottom mold and tighten the clamping bolts to tension the prestressed steel bars; step E, place the production mold on a centrifuge for centrifugation, and then enter the curing pool for maintenance; finally demould and leave the warehouse; and the production mold Auxiliary devices used in conjunction with the process include a vibrating material distribution vehicle and a material introduction mold; the invention solves several problems in the mold opening material distribution process and the mold closing pump material process on product quality, environmental pollution, cost consumption, production efficiency, and resource waste.

Description

technical field [0001] The invention belongs to the technical field of production of concrete and cement product piles and utility poles, and in particular relates to a production process of centrifugal slurry-free pile poles, a supporting material introduction mold and a vibrating distribution vehicle. Background technique [0002] At present, in the production process of concrete piles, two production processes are mainly used: one is the mold opening and distribution process, and the other is the mold closing and pumping process. Now most of the production process of centrifugal concrete piles is the process of mold opening and distribution. When the mold opening and distribution process is used for production, after the concrete is distributed, the concrete will generally scatter on the ground or on the side of the mold, requiring workers to shovel the material into the mold. The clamping bolts are tightened, and then prestressed tensioning, centrifugal forming, residua...
