Application of The LGZ Hydraulic multifunctional Drilling Rig in complex stratum
Abstract:LGZ series full hydraulic multi-functional pile driver has three patented technologies, i.e. axial sliding active drill pipe, large torque hollow rotary power head and double drum synchronous winch. It has the technical advantages of construction safety, multiple functions of one machine, stable and efficient transmission. This paper introduces the performance parameters and technical characteristics of this series of pile drivers, and their application in five construction methods, such as screw pile, screw soil extrusion pile, cement soil mixing pile, long screw bored pile and large diameter long screw bored pile. It has been proved that LGZ series full hydraulic multifunctional pile driver can meet the construction requirements of various pile foundation construction methods and can be extended to more application of construction methods.
