Crushing device, breaking method and application of pile head of cast-in-place bored pile

Abstract

The invention discloses a crushing device, a breaking method and an application of a pile head of a cast-in-place bored pile. The crushing device of the pile head of the cast-in-place bored pile comprises the crushing device, wherein the crushing device is used for separating pile head concrete from pile body concrete through horizontal expansion force; the crushing device comprises a horizontal crushing assembly and a communicating pipe, wherein the horizontal crushing assembly is arranged at the joint position of the pile head concrete and the pile body concrete, and the horizontal crushingassembly is used for generating the horizontal expansion force to force the pile head concrete to be separated from the pile body concrete; and the communicating pipe extends out of the pile head concrete and is in communication with the inner cavity of the horizontal crushing assembly, and is used for injecting a crushing agent into the inner cavity of the horizontal crushing assembly. Accordingto the crushing device of the pile head of the cast-in-place bored pile, the structural design is simple, the crushing device of the pile head of the cast-in-place bored pile is placed at the joint position of the pile head concrete and the pile body concrete, and the separating effect can be achieved by injecting the crushing agent.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a crushing device for bored cast-in-place pile heads. In addition, the present invention also relates to a breaking method and application of the crushing device comprising the pile head of the cast-in-place pile. Background technique [0002] In the construction of construction projects, bridge engineering, urban rail transit and other engineering projects, the technology of bored piles is widely used. The wall of bored piles is usually made of mud wall, and the pile head is broken by traditional manual breaking method and small mechanical breaking. The method, the ring knife method, the ring chisel method, etc., are prone to environmental pollution during the construction process, and the dust generated during the demolition has a great impact on the health of the workers. The pile head steel bars are easy to bend or even break, and the quality cannot be guarantee...
