Bidirectional cement mixing pile anti-blocking pipe
The invention provides a bidirectional cement mixing pile anti-blocking pipe. The pipe comprises an outer drill rod and an inner drill rod, the inner drill rod is sleeved with the outer drill rod, thelower end of the inner drill rod extends out of the outer drill rod and is a drill bit part, at least one outer drill rod cutter is fixedly connected to the outer wall of the lower portion of the outer drill rod, and at least one inner drill rod cutter is fixedly connected to the outer wall of the inner drill rod extending out of the lower side of the outer drill rod. The bottom of the outer drill rod and the side wall of the inner drill rod are sealed through a sealing assembly. The sealing shell comprises an annular tray and a sealing flange plate, the annular tray is fixedly connected to the side wall of the inner drill rod extending out of the lower side of the outer drill rod, the upper end of the annular tray is open, the sealing flange plate covers the opening of the annular tray,the sealing flange plate is fixedly connected with the annular tray, and the outer drill rod penetrates through the sealing flange plate and extends into the annular tray. A gap is formed between theouter drill rod and the closed flange plate, and the sealing filler is packing. The anti-blocking pipe has the advantages of being diverse in function, good in sealing effect and capable of better meeting operation design requirements.
本发明给出了一种双向水泥土搅拌桩防堵管；包括外钻杆和内钻杆，内钻杆套装在外钻杆内，内钻杆下端伸出外钻杆外，内钻杆下端为钻头部，外钻杆下部外壁固定连接有至少一个外钻杆刀盘，伸出外钻杆下侧的内钻杆外壁固定连接有至少一个内钻杆刀盘；外钻杆底部与内钻杆侧壁之间通过封闭组件密封。密封壳体包括环形托盘和封闭法兰盘，环形托盘固定连接在伸出外钻杆下侧的内钻杆侧壁上，环形托盘的上端开口，封闭法兰盘覆盖在环形托盘的开口处，封闭法兰盘与环形托盘固定连接，外钻杆贯穿封闭法兰盘且伸入环形托盘内，外钻杆与封闭法兰盘之间具有间隙,密封填充物为盘根。本防堵管有益效果为：功能多样、密封效果好，更能符合作业设计需要。
