Equipment for producing concrete pipe pile and method for producing concrete pipe pile by using equipment

Abstract

The invention discloses equipment for producing a concrete pipe pile and a method for producing the concrete pipe pile by using the equipment. The equipment is characterized by comprising a pipe pile mold and a conveyor for filling concrete in the mold, wherein a discharging port of the conveyor is provided with a feeding steel pipe capable of extending into the pipe pile mold; the pipe pile mold is arranged on a material distributing flat wagon which is provided with an electronic metering scale; the pipe pile mold is loaded on the electronic metering scale; and the equipment further comprises an electric control device which can control the movement speed of the material distributing flat wagon according to the value change condition of the electronic metering scale in the process of casting concrete. The invention provides the equipment which is simple in structure, can realize closed concrete casting and is applicable to producing pretensioning prestressed concrete pipe piles for the purpose of overcoming the defects in the prior art. Another purpose of the invention is to provide a method for producing the concrete pipe pile by using the equipment.

Description

technical field [0001] The invention relates to a device for producing concrete pipe piles, and also relates to a method for using the device to produce prestressed concrete pipe piles. Background technique [0002] In the production process of tubular piles or hollow square piles, the traditional concrete pouring method is to use the open pouring method: the mold used for the production of tubular piles or hollow square piles is divided into an upper mold and a lower mold or a cover mold and base mold. Before pouring concrete, cage bars and end plates are installed in the bottom form, head plates and baffles are installed at the head end of the bottom form, and tail plates are installed at the tail end. There are two ways to pour concrete: one is to pour the concrete evenly into the bottom form by moving the trolley with concrete back and forth on the upper part of the bottom form; the other is to place the bottom form on a flat car and pass it Moving back and forth, the ...

AI Technical Summary

Problems solved by technology

[0003] 1. During the pouring process, the concrete tends to slip from both sides of the bottom mold, and then it is manually shoveled back into the bottom mold, which affects the quality of the concrete; if the slipping material is not shoveled into the bottom mold in time, it is easy to cause waste of materials and damage the environment. Pollution; when there is more slipping material, it will cause less material, which will cause negative deviation in the wall thickness of the pile, etc.;

[0004] 2. Concrete slips to the edge of the mold during pouring. When the cover mold is closed after pouring, the mold will not be tightly closed, and there will be a gap between the upper and lower molds. During centrifugation, there will be grout leakage at the seam, causing quality problems

[0005] 3. During the concrete pouring process, due to uneven concrete blanking, it is necessary to manually spread the concrete shovel evenly, so the number of workers is large, the labor intensity is high, and the work efficiency is low

[0006] 4. Concrete can only be poured first and then stretched by the open pouring method. If there is a failure in the tensioning process, such as main reinforcement breaking, end plate pulling off, etc., it will affect the time and even cause the concrete to be scrapped.
