Embodiment Construction

[0016] In the construction of pile foundations in existing rock layers, the construction technology and construction machines and tools cannot achieve low-cost and high-efficiency construction goals. Conventional construction machines and tools have extremely low construction efficiency in rock layers, and have extremely high requirements on the performance of the machinery itself, and the construction limitations are large. . An embodiment of the present invention provides a rock formation piling drill bit.

[0017] like figure 1 , figure 2 and image 3 As shown, the rock layer piling drill bit includes a plurality of drill bit units, and a fixing device is provided between each of the drill bit units. The drill bit unit includes a percussion drill 1 and an impact driver 6 that drives the percussion drill to reciprocate and impact. The drill bit unit is connected as a whole through the fixing device, which can not only realize the overall rotary cutting of the drill bit, ...

Abstract

The invention aims to provide a lithosphere piling drill to solve the problem that the construction technology and construction equipment in the existing lithosphere pile foundation construction cannot reach the construction goal of low cost and high efficiency. The conventional construction equipment is of extremely low construction efficiency in the lithosphere, has super high requirements for equipment performance itself and has the problem of big construction limitation. The lithosphere piling drill comprises a plurality of drill units, wherein fixing devices are arranged among each two drill units. The drill unit comprises a percussion drill and a percussion driving device for driving the percussion drill to give repeated percussions. The lithosphere piling drill can be applied into the field of pile foundation construction.

Description

technical field [0001] The invention relates to the field of drilling tools, in particular to a piling drill bit. Background technique [0002] At present, in the construction of pile foundations in rock layers around the world, construction techniques and construction machines cannot achieve low-cost and high-efficiency construction goals. With the progress of society, the requirements for earthquake resistance of buildings are getting higher and higher, and driving the pile foundation into the rock layer is the best way to solve the requirements for earthquake resistance on the foundation. Conventional construction methods have extremely low construction efficiency in rock layers, have extremely high requirements on the performance of the machinery itself, and have large construction limitations. Contents of the invention [0003] The purpose of the present invention is to provide a rock layer piling drill bit, which solves the problem that in the existing rock layer pi...
