Equipment and method for producing concrete tubular pile

Abstract

The invention discloses equipment for producing a concrete tubular pile, which comprises a tubular pile die, wherein the tubular pile die comprises an upper die and a lower die; one end of the tubular pile die is provided with a material conveying steel tube which stretches into the tubular pile die and can produce relative movement with the tubular pile die; one end of the material conveying steel tube is provided with a feed hopper; and a spiral conveying device capable of conveying concrete in the feed hopper into the tubular pile die is arranged in the material conveying steel tube. In order to overcome the defects in the prior art, the invention aims to provide the equipment for producing the concrete tubular pile, which has a simple structure, can solve the problem of product disqualification caused by leaking slurry from a joint seam, effectively reduces the number of labor force and improves the production efficiency. The invention has the other aim to provide a method for producing the concrete tubular pile by adopting the equipment.

Description

technical field [0001] The invention relates to a device for producing concrete pipe piles; the invention also relates to a method for producing concrete pipe piles by using the device. Background technique [0002] In the prior art, the sequence of producing concrete pipe piles is generally to install steel cages first, lay concrete materials, close molds, post-tension, and then centrifugally form. The concrete pipe piles produced by this method mainly have the following defects: [0003] 1. In terms of quality: the produced concrete pipe piles have the phenomenon of grout leakage at the joints and wide joints, etc. At the same time, the pipe piles are easy to be broken during construction and affect their service life; [0004] 2. In terms of equipment: when the steel mold is closed, it is difficult to close it tightly due to the falling of concrete particles, resulting in a large gap between the running wheels of the upper and lower molds, which causes the steel mold to ...
