The successful research of this brand new process method has realized the possibilities for the construction workers to conduct the construction of casing pipe, 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, various pile foundation and steel reinforced concrete structure, are not removed.
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 and Tianjin. It certainly will play a bigger role in the future urban construction and other pile foundation construction fields.

Frequently Asked Questions
What is a casing rotator and where is it used?
A casing rotator is a new, highly efficient, and environmentally-friendly drilling technology featuring integrated hydraulic power, transmission, and multi-system controls. It is widely used in urban subway construction, deep foundation pit articulation piles, waste pile clearance, high-speed rail, road and bridge construction, and reservoir dam reinforcement.
Can the casing rotator operate in complex geological formations?
Yes. The construction method allows successful pile foundation operation in difficult strata such as gravel and boulder formations, karst caves, thick quicksand layers, strong necking down formations, and directly through steel-reinforced concrete structures without pre-removal.
What are the environmental benefits of the casing rotator?
The casing rotator operates with zero vibration and minimal noise. Additionally, it does not require drilling mud, keeping the working surface clean and eliminating the risk of mud contaminating the concrete, which results in higher overall pile quality.
What is the drilling speed and maximum depth capabilities?
The casing rotator delivers high drilling speeds of approximately 14 meters per hour in standard soil layers. Depending on the soil conditions, it can achieve a maximum drilling depth of up to 80 meters.
How accurate is the verticality of the hole forming?
The verticality of hole forming is exceptionally easy to master and can be accurately controlled to 1/500. This ensures high-quality hole forming and prevents hole collapse during drilling.
How does the casing rotator clear underground obstructions?
During urban construction or bridge rebuilding, the casing rotator can directly cut and clear underground obstructions—including steel reinforced concrete piles, steel pipe piles, H-steel piles, PC piles, and wood piles—allowing new foundation piles to be cast in-place directly on site.
