冲抓钻机是四川省建工局科研所研制成的用于爆扩桩基础成孔的专用机械。在含有块石等坚硬夹杂物的粘性土或碎面类十地区,如采用人工和已有的机械旋转钻成孔是比较困难的,他们研制成功的冲抓钻机就能很好的胜任这方面的成孔工作。该机的冲抓锥可以利用一个简易的三角架作机体,也可以装在一部汽车低盘上。冲抓锥头重800公斤,用它成孔时,迂 The Rush Drilling Rig is a special machine developed by the Sichuan Institute of Construction Industry and Engineering for the purpose of forming holes for blasting and expanding pile foundations. In cohesive soils or smashed surface areas containing hard inclusions such as lumps, it is difficult to manually drill and drill holes with existing machines. The successfully developed rush-climbing rigs will be able to perform well in this area. The hole work. The punching cone of the machine can use a simple tripod as the body, or it can be mounted on a car low plate. The head weight of the rushing cone is 800 kg. When it is used as a hole,
