Novel circulating use method for residual grout of PHC pipe pile

Abstract

The invention discloses a new PHC pipe pile residual pulp circular using method. It includes following processes: (1) the residual pulp generated after the centrifugal process in process of PHC pipe; (2) the collected residual pulp is confected with water; (3) the confected residual pulp and the other material for PHC pipe are mixed together, the total quantity of glue material in residual pulp is consistent to the quantity of glue material in supplementary material; (4) the mixed material is produced according to the PHC pipe producing process; (5) the residual pulp generated in the process enters the next circulation. The method can reduce the consumption of glue condensing material, and it has no contamination to environment.

Description

technical field [0001] The invention relates to a process for recovering excess slurry of a novel PHC pipe pile. Background technique [0002] At present, the output of PHC pipe piles (ultra-high-strength prestressed concrete pipe piles) is huge. The raw materials of PHC pipe piles are composed of river sand and stones that constitute aggregates, cement, finely ground sand, water, and water reducing agents that fill the gaps between aggregates and act as coagulation materials. The concrete strength must reach C80 grade. . In the production process, each raw material is mixed with a mixer according to the formula to prepare a mixture, and then the mixture is fed into the steel mold of the pipe pile, and then undergoes processes such as tensioning prestressed steel bars, centrifugal forming, and steam curing. In the production process of PHC pipe piles, the residual slurry separated during centrifugal forming also brings huge pressure to the society. There are basically two...

Problems solved by technology

Although this method solves the problem of environmental pollution and makes the wastes utilized, there are also the following problems: (1) but due to the small scale of aerated and cut pieces, the utilization benefit is not high, and the technology is not easy to popularize; (2) From the production of slurry to the production of aerated blocks, due to the amount of residual slurry produced and the distance between the two production sites, the collection and transportation of residual slurry must cause its residence time to be long, causing the gelling material to coagulate and sedimentation, so that the remaining slurry cannot be used in time in the most favorable time, so that its performance is not fully exerted

(3) This treatment method also needs to purchase additional equipment, resulting in increased input costs, and this method will produce secondary slag, so this method is not an ideal treatment method for residual pulp
