Abstract

A concrete pipe pile production technology capable of recycling residual grout, and relates to the technical field of tubular production. The technology is characterized by sequentially comprising the following steps of compounding, stirring, feeding, centrifugal forming, residual grout collecting, residual grout processing, residual grout recycling and compounding. According to residual grout processing, the residual grout is diluted and stirred, the proportion of the diluted residual grout is 1.40+ / -0.02g / cm<3>. The residual grout waste liquid can be fully utilized. In the actual production, a residual grout recycling system is used. Due to utilization of the residual grout, in concrete per cubic metre, 35 kilograms of sand and 45 kilograms of water can be saved, and meanwhile the garbage disposal cost can be reduced. Due to application of the technology, the pollution caused by the residual grout can be effectively prevented, and the environmental protection problem is solved.

Description

Technical field: [0001] The invention relates to the technical field of tubular production, in particular to a production process for concrete tubular piles for recycling residual slurry. Background technique: [0002] PHC pipe piles are processed and manufactured using a centrifugal forming mechanical dehydration and compaction process. During the high-speed centrifugal forming process, the concrete mixture is compacted by centrifugal backlog, which will produce residual slurry (after analysis, its main components are water, cement, and fine sand. ﹑mineral impurities, etc.), which has brought a big problem to pipe pile manufacturers-the disposal of residual slurry. At present, many pipe pile manufacturers are researching and developing the treatment of pipe pile residual slurry, such as road side stones, hollow bricks, etc., or discharge to open space, centralized storage, road padding, and waste treatment, which will cost a lot of money and manpower, and cause Environment...
