Full casing rotary drilling is a new, environmentally friendly and efficient drilling technology. In recent years, it has been widely used in urban subway, deep foundation pit enclosure bite pile, waste pile (underground obstacle) cleaning. high-speed railway, road and bridge, urban construction pile construction, reservoir dam reinforcement and other projects.

The succesful research of this brand new process method has realized the possibilities for the construction workers to conduct the construction of casting piple, displacement pile, and underground continuous 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 formation and various pile foundtion.

The construction method of casing rotator has successfully 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 bigger role in the future urban construction and other pile foundation construction fields.
