The casing rotator is a new type drill with the integration of the full hydraulic power and transmission and the combination control of machine, power, and fluid. It is a modern, environmental, and highly efficient drilling technology. In recent years, it is widely adopted in projects such as the constructions of urban subway, articulation pile of deep foundation pit enclosure, clearance of waste piles (underground obstructions), high-speed rail, road and bridge, and municipal construction piles, as well as the reinforcement of the reservoir dam.
The successful research of this brand new process method has realized the possibilities for the construction workers to conduct the construction of casting pipe, displacement pile, and continuous underground wall, as well as the possibilities for the pipe-jacking and shield tunnel to pass through the various pile foundations without barriers, when the obstructions, such as the gravel and boulder formation, cave formation, thick quicksand stratum, strong necking down the formation and various pile foundations.
The construction method of casing rotator has completed construction missions of more than 5000 projects at places of Singapore, Japan, Hongkong District, Shanghai, Hangzhou, Beijing, Tianjin, and Chengdu. It certainly will play a more prominent role in the future urban construction and other pile foundation construction fields.
