And precast pile, bored pile construction of no noise, no vibration, on the surrounding buildings and small environmental impact, pile diameter, buried deep, large bearing capacity. Chinas drilling pile maximum diameter of pile has reached 4000mm, maximum deep pile has reached 104m, and the steel pipe pile maximum diameter of 1200mm, the largest pile of prestressed concrete pipe pile with deep 83m, maximum diameter of 1300mm, the biggest pile depth 40m. Along with our country socialist construction is booming, with high-rise buildings, large span bridges on the rise, the bearing capacity of pile foundation with higher requirements. Large diameter bored pile therefore gets rapid development, pile length and pile diameter also do bigger more. However, in the existing various methods of pile, bored pile has many advantages and is widely used in construction, but it is hard to avoid the impact of mud, which not only reduces the bearing capacity of pile expectations, but also caused a serious waste of materials. Manual hole digging pile is difficult to achieve greater depth, its bearing capacity is also difficult to just as one wishes. In view of bored pile in this situation, how to improve the pile const
