High-pressure injection drilling tool
The invention discloses a high-pressure injection drilling tool. The high-pressure injection drilling tool comprises a water spraying assembly, a slurry returning assembly, a monitoring assembly, an upper guniting assembly, a lower guniting assembly and a drill bit assembly which are sequentially connected from top to bottom; water nozzles are inserted into two opposite sides of a water nozzle seat of the water spraying assembly respectively; and a first nozzle assembly of the upper guniting assembly and a second nozzle assembly of the lower guniting assembly are distributed on the two opposite sides. The counter-acting force of the two water nozzles and the counter-acting force of the two nozzle assemblies acting on the drilling tool are opposite in direction and counteract mutually, the influence of the counter-acting force on the drilling tool is avoided, the drilling tool is prevented from inclining, and the straightness of a pile hole is guaranteed.
本发明公开了一种高压喷射钻具，包括从上至下依次连接的喷水组件、返浆组件、监测组件、上喷浆组件、下喷浆组件及钻头组件；喷水组件的水喷嘴座上相对的两侧分别插装有水喷嘴；上喷浆组件的第一喷嘴组件与下喷浆组件的第二喷嘴组件分布在相对的两侧。本发明的两水喷嘴及两喷嘴组件作用在钻具上的反作用力方向相反、相互抵消，避免了反作用力对钻具造成影响，防止钻具发生倾斜，保证桩孔的直线度。
