The dive impactor is also called the pneumatic percussion device and the pneumatic DTH hammer. With compressed air as a dynamic medium, the power machine with a continuous impact load is produced by using the energy of compressed air to produce a continuous impact load. Compressed air can also be used as a hole washing medium. The pneumatic impactor has high wind pressure and low wind pressure, valve type and valveless type. Usually, the pneumatic impactor is directly connected with the hard alloy column tooth bit to break the rock with the impact mode, and the low speed rotation does not take the core in full drilling. It is mainly used in the fields of hydrologic well drilling, non core geological drilling, geological disaster prevention and control engineering, and mine rock drilling. It is suitable for application in gravel and hard rock, and the bit with special structure can also be used in soft soil. The mechanical drilling speed is generally much higher than the hydraulic impactor drilling, but it needs to be equipped with a large capacity air compressor, the fuel consumption is larger, and there is noise and dust pollution. The drilling depth is greatly influenced by the water level and water level of the groundwater.
