Pile foundation casing embedding and pile pole drilling all-in-one machine

Abstract

The invention relates to a pile foundation casing embedding and pile pole drilling all-in-one machine. The machine comprises a bearing system, a drilling system, a casing embedding system and a guide tube lifting system; the drilling system comprises an air compressing machine set, a drill rod device, a revolving device and a drill bit; the casing embedding system comprises a casing and a casing connector; the casing comprises an inner wall and an outer wall; the casing connector is connected with the casing through a circumferential screw thread; the casing embedding drill rod is installed between the drill rod and the casing connector; the lower part of the casing embedding drill rod is connected with the casing connector; the casing has a double-wall hollow structure; the casing connector has a double-wall hollow structure; the guide tube lifting system comprises a hoist and a guide tube carrying steel bar concrete; the hoist is connected with the guide tube through wire ropes. The invention provides a pile foundation casing embedding and pile pole drilling all-in-one machine and solves the technical problems that hole collapse may occur during soft ground pile foundation drilling, and embedded casing is too long and cannot be pulled out so that material is wasted.

Description

technical field [0001] The invention relates to an integrated machine for pile foundation casing embedding and pile hole drilling, which is applied in the field of construction pile foundation engineering devices. Background technique [0002] During the construction of building pile foundation, it is often carried out under different geological conditions. When encountering soft geology, if the geological layer is relatively thick, hole collapse often occurs during drilling or after hole formation. In order to solve the problem of pile hole collapse, the construction of building pile foundations mostly adopts mud retaining wall drilling or casing drilling for construction. However, both mud wall drilling and casing method drilling have their own problems. Specifically, during the mud wall drilling process, a large amount of waste mud will be generated, which will not only pollute the construction site, but also have a certain impact on the surrounding environment. At the ...
