Long spiral air-entrapping device used in cohesive soil rock stratum and grouting pile-forming construction method
The invention provides a long spiral air-entrapping device used in a cohesive soil rock stratum and a grouting pile-forming construction method, and relates to the technical field of cohesive soil rock grouting pile, the long spiral air-entrapping device comprises a drilling machine body, an air-entrapping transition piece, a spiral drill rod and a conical drill bit; an air compressor and an air storage tank are sequentially installed at one end of the drilling machine body, the other end of the air storage tank is further connected with an air outlet transverse pipe and communicated with the air-entrapping transition piece through a telescopic hose, the outer side of the air-entrapping transition piece is fixedly connected with the drilling machine body, and the conical drill bit is connected to the bottom of the spiral drill rod through threads. A connecting flange is welded to the top end of the spiral drilling rod and connected with a flange bolt at the bottom end of the drilling machine driving rod. The spiral drill bit can blow off argillaceous siltstone adhering to the spiral drill rod, the breather pipe and the telescopic hose are not prone to damage, air holes in the conical drill bit are not prone to being blocked, cleaning is convenient, and the problems that the breather pipe is prone to being broken and blocked, and the conical drill bit is not prone to being cleaned are solved.
本发明提供了一种粘性土岩地层中用长螺旋加气装置及灌注成桩施工法，涉及粘性土岩灌桩技术领域，包括：钻机体、加气过渡件、螺旋钻杆和锥形钻头；所述钻机体的一端依次安装有空压机和储气罐，所述储气罐的另一端还连接有出气横管，并与加气过渡件通过伸缩软管相连通，加气过渡件的外侧与钻机体固定相连，所述锥形钻头通过螺纹连接在螺旋钻杆的底部，螺旋钻杆的顶端焊接有连接法兰，并与钻机驱动杆底端的法兰螺栓连接。能够将粘附于螺旋钻杆上的泥质粉砂岩吹掉，而且通气管与伸缩软管不宜损坏，锥形钻头上的气孔也不宜堵塞，还方便清理，解决了通气管容易破裂与堵塞，锥形钻头不宜清理的问题。
