For loess and clay strata, especially for the arid and water shortage areas in Northwest China, the rotary drilling rig adopts mud free dry drilling to form holes, which has a fast drilling speed. It is not limited by the site, and its advantages can be better reflected in the construction work on the site with tight power. The drill has its own power and is easy to move. There is no mud, less sediment after hole forming, and the pile is poured by anhydrous conduit method, which has outstanding safety and environmental protection characteristics.
