Static breaking construction method for interior of cast-in-situ bored pile head

Abstract

The invention discloses a static breaking construction method for the interior of a cast-in-situ bored pile head. The static breaking construction method comprises the following steps that S1, a cast-in-situ pile hole is formed, and a reinforcement cage is manufactured; S2, a pipe fitting is pre-buried in the pile head, a sleeve at the top of the reinforcement cage is installed, and the reinforcement cage is lowered; S3, solid pile concrete is poured; S4, the pile head is excavated and cleaned; S5, the pile head splitting line is cut, and the embedded pipe fitting is poured with an expanding agent; and S6, the interior of the pile head is statically expanded and cracked. The construction method is easy to operate and environmentally friendly, the investment of traditional pile head breaking constructors and machines is greatly reduced, the pile head breaking amount, noise and flying dust are reduced, the pile head breaking construction quality is guaranteed, the pile head breaking construction efficiency is improved, and the construction cost is reduced.

Description

technical field [0001] The invention relates to the field of breaking pile heads of cast-in-place piles. More specifically, the invention relates to a construction method for static breaking inside the pile head of a bored cast-in-place pile. Background technique [0002] At present, in order to ensure the quality of the pile head, especially when the underwater pouring pile is overfilled by 800-1000mm, the overfilled part of the pile head after forming is mainly broken by manual use of pneumatic picks, blaster or hydraulic pile cutter to break the pile head from the outside , Get rid of loud noise, big dust, big space demand and low efficiency. [0003] Therefore urgently need to develop a kind of new bored cast-in-place pile head internal static breaking method to make up for this deficiency. Contents of the invention [0004] The purpose of the present invention is to provide a construction method for internal static demolition of the pile head of bored cast-in-situ p...
