Casing Rotator

Overview

   

 

The casing rotator is a new integration of the full hydraulic power and transmission, and the combination control of machine, power and fluid.

It is a new, environmentally-Friendly and highly efficient drilling technology. In recent years, it is widely adopted in the projects such as the constructions of urban subway, articulation pits of deep foundation pit enclosure. clearance of waste piles(underground obstructions),high-speed rail, road and bridge, and urban construction piles, as well as the reinforcement of 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 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.

 

 

Foundation pile, continuous wall

■  Foundation piles far high-speed rail, road and bridge and house building

■  Articulation pile constructions which are required to be excavated. such as subway platforms, underground architectures, continuous walls

■  Water retaining wall of reservoir reinforcement

 

Drilling gravels, boulders and karst cares

■  It is allowable to conduct the foundation pile construction at mountain lands with gravel and boulder formations

■  It is allowable to conduct operation and cast the foundation piles at the thick quicksand formation and necking down stratum or the filling layer

■  Conduct rock-socketed drilling to the rock stratum. cast the foundation pile

 

Clear the underground obstructions

■  During the urban construction and bridge rebuilding, the obstructions such as the steel reinforced concrete pile, steel pipe pile, H steel pile, pc pile and wood pile can be cleared directly, and cast the foundation pile on the spot.

 

Cut the rock stratum

■  Conduct the rock-rocketed drilling to the cast-in-place piles.

■  Drill through-holes on the rock bed (shafts and ventilation holes)

 

Deep excavation

■  Conduct the in-place casting or steel pipe pile inserting for the deep foundation improvement.

■  Excavate deep wells for construction use in the constructions of reservoir and tunnel.

The automatic control device, which is the cutter head

load control device, controls the pressure of thrust

hydraulic oil cylinder , makes the cutter head load

constant with the changes of the casing weight and

different resistance. It keeps the machine in its optimum

working state.

 

This is the most advanced automatic control system

available. It is a perfect representation of the integrated

machine, power and fluid, which has greatly enhanced

the safety and working efficiency.
