25 Ton All Casing And Rotation Drilling Rig Diesel Power And 600-1300 mm Diameter

Vertical Hydraulic Casing Rotator Safe Accurate With No Vibration

1.The components of casing rotator series

1) Working device

Wedge clamping device---Being compared with the traditional clamping mechanism, it can clamp the casing no matter at what position, and keep the vertical accuracy of the casing; and the larger drawing resistance of casing causes greater lamp force.

2) Motor Reducer---4 sets of motor reducer can supply the sufficient torque, transfer a strong rotary force to the casing, which can adapt to the complicated stratum and cut obstructions.

3) Vertical device---Hydraulic vertical device ensures the verticality of drill holes, and corrects the casing angle timely in the construction.

4) Caliber change device---The convenient caliber change makes the equipment adapt to various requirements of caliber change.

5) Auxiliary clamping device---It can better ensure the verticality of casing, and additionally compensate for the problem of low crane capacity of the equipped crane during deep excavation.

6) Work traveling device---The crawler traveling device is with the function of hydraulic transverse expansion, which is convenient for the equipment to move automatically and conduct the pile core localization.

2. Introduction to construction method

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 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 pile 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 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.

1) Foundation pile, continuous wall:

Foundation piles for 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.

2) Drilling gravels, boulders and karst caves

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 he thick quicksand formation and necking down stratum or the filling layer.

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

3) 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.

4) Cut the rock stratum

Conduct the rock-socketed drilling to the cast-in-place piles.

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

5) 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.

3. The advantages of adopting the casing rotator for construction

1) No noise, no vibration, and high safety;

2) Without mud, clean working surface, good environmental friendliness, avoiding the possibility for mud to enter the concrete, high pile quality, enhancing the bond stress of concrete to the steel bar;

3) During construction drilling, the characteristics of stratum and rock can be directly distinguished;

4) The drilling speed is fast and reaches about 14m/h for the general soil layer;

5) The drilling depth is large and reaches about 80m according to the situation of soil layer;

6) The hole forming verticality is easy to master, which can be accurate to 1/500;

7) No hole collapse will be caused, and the hole forming quality is high.

8) The hole forming diameter is standard, with little filling factor. Being compared with other hole forming methods, it can save a lot of concrete usage;

9) The hole clearing is thorough and fast. The drilling mud at the hole bottom can be clear to about 3.0 cm.
