Hydraulic Engineering Percussion Drilling Rig
Percussion drilling is a manual drilling technique in which a heavy cutting or hammering bit attached to a rope or cable is lowered in the open hole or inside a temporary casing. The technique is often also referred to as 'Cable tool'. Usually a tripod is used to support the tools. By moving the rope or cable up and down, the cutting or hammering bit loosens the soil or consolidated rock in the borehole, which is then extracted later by using a bailer. Just as with hand augering, a temporary casing of steel or plastic may be used to prevent the hole from collapsing. When the permanent well screen and casing are installed, this temporary casing has to be removed.
The percussion borehole drilling rig's technical advantages:
- Unlike any other drilling method, percussion can remove boulders and break harder formations, effectively and quickly through most types of earth.

- Percussion drilling can in principle deal with most ground conditions.
- Can drill hundreds of feet (one well hand-drilled in China in 1923 was over 4000 feet deep).
- Can drill further into the water table than dug wells, even drilling past one water table to reach another.
