Construction method of pile breaking head of cast-in-place pile, auxiliary isolation net and preparation method of auxiliary isolation net

Abstract

The invention discloses a construction method of a pile breaking head of a cast-in-place pile, an auxiliary isolation net and a preparation method of the auxiliary isolation net. According to the method, a plurality of plastic pipes with different diameters are nested, and then the plastic pipes are fixed through radial reinforcing bars to form the auxiliary isolation net; in the concrete pouringprocess of the cast-in-place pile construction, when concrete is poured to the position of the design elevation, the auxiliary isolation net is fixed on a reinforcing cage at the position of the design elevation; concrete is continued to be poured until the pile breaking head is poured; and after the concrete of the cast-in-place pile is solidified and reaches a pile breaking state, the concrete above the auxiliary isolation net is struck by using a pile breaking machine, the pile head above the design elevation is broken down, and the construction of the pile breaking head of the cast-in-place pile is completed. The auxiliary isolation net has the advantages of simple structure, high practicability, low cost and good use effect; and therefore, the construction efficiency can be obviouslyimproved in the process of the pile breaking head of the cast-in-place pile, the damage to a main pile body in the process of breaking the pile can be greatly reduced, and the related construction technical problems in the process of the pile breaking head can be solved.

Description

technical field [0001] The invention belongs to the field of construction and relates to a construction method of a cast-in-place pile, in particular to a construction method of a broken pile head of a cast-in-place pile, an auxiliary isolation net and a preparation method of the auxiliary isolation net. Background technique [0002] With the development of society, the construction industry has also ushered in huge changes. Various modern demands have made the construction technology requirements of the construction industry more and more strict. In the part of foundation construction, the construction of cast-in-place piles also faces huge challenges. Changes, large diameter and high quality have become a rigid requirement; for the construction of large diameter cast-in-place piles, since the quality of the top surface concrete cannot meet the requirements after solidification, in order to ensure the quality of the concrete pile body, it must be poured beyond the pouring pr...
