| Abstract: | Taking the example of pile foundation engineering of Sanguo Grand Theater of Xuchang City, the difficulties encountered in hard formations by ordinary long spiral drilling machine, hydraulic driving head drill and high weight and large torque dynamic head drill with frequency conversion technology are presented with the related countermeasures. The adaptability to formations are discussed for various models of long spiral pile hole drilling machine to provide reference for construction machinery selection in similar engineering. |
