Production method of concrete tube pile

Abstract

The invention discloses a production method for a concrete tube pile, which comprises the following steps: A, loading the cage rib required for the production of the tube pile into a mould, closing the upper and the lower dies of the mould and tightening a screw; B, stretching the cage rib in the mould and applying prestress force; C, delivering the pre-prepared concrete into the hollow chamber of the mould; and D, hoisting the mould onto a centrifuge to carry out a centrifugal shaping. The aim of the invention is to overcome the defects in the current technology and to provide a concrete tube pile production method having the advantages of simple technique, convenient processing, low cost, stable product quality and high production efficiency.

Description

technical field [0001] The invention relates to a production method of concrete pipe piles. 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 jump when it is centrifuged, and damages the steel mold and the centrifuge; [0005] 3. In te...
