Treatment construction method for hollow hole section of long spiral pile

Abstract

The invention discloses a treatment construction method for a hollow hole section of a long spiral pile, and belongs to the field of building construction. The long spiral pile reinforcement cage installation structure comprises a vibration hammer, a force transmission rod and a steel protection cylinder, wherein the length of the steel protection cylinder is the same as that of the hollow hole section of the long spiral pile, and a long spiral pile machine is used for firstly taking soil to an elevation of the pile top, so that the steel protection cylinder is directly lowered in place; the vibration hammer is connected with the force transmission rod for operation through an auxiliary hook of the long spiral pile machine, the vibration hammer is powered by external power equipment, the vibration hammer transmits power for mounting a reinforcement cage, the force transmission rod is mounted all the way to the bottom of the reinforcement cage, and the length of the force transmission rod is 1-2 m longer than the sum of the length of the long spiral pile and the hollow hole section. According to the treatment construction method for the hollow hole section of the long spiral pile, the steel protection cylinder is adopted to protect the hollow hole section of the long spiral pile, the hole wall muck is prevented from falling into a hole due to vibration, the steel reinforcement cage is mounted to the designed elevation through the vibration hammer using a suitably long force transmission rod, and construction is convenient.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method for treating empty hole sections of long screw piles. Background technique [0002] In the construction of long screw piles, if the pile top elevation of the long screw pile is below the ground, after the concrete is poured into the ground, the steel cage is sent to the design elevation by using the long screw pile machine drill pipe, but after the earth excavation It is also necessary to break the piles up to the design elevation, so that the construction will cause a lot of waste of concrete, and increase construction waste and labor costs. Contents of the invention [0003] In order to overcome the defects of the prior art, the technical problem to be solved by the present invention is to propose a construction method for treating the hollow section of the long screw pile, which solves the waste of concrete caused by construction when the ...
