Product Desciption
Advantages:
Casing technology
1. Casing driver
Through the connection of power head with casing adaptor, casing driver, casing and casing shoe, torque and pressure are transferred to casing and casing shoe. The drilling process alternates between casing drilling and drilling tool taking out the soil for lower resistance of casing drilling.
3. Vibrating hammer
The crawler crane lifts the vibration hammer, the hydraulic clamp at the bottom of the vibration hammer holds the top of the casing. The vertical vibrating force of eccentric wheel acts on the casing to drill into the hole or pull out from the hole.
Pile casing system mainly consists of the following parts:
1. Cardanic joint
The cardanic joint is for connecting the power head with bolts and casing driver with pins, which is used to transmit torque and pressure.
2. Casing driver
The diameter of the casing driver shall be consistent with the casing diameter; the bottom of the casing driver shall be connected with the casing. The function of casing driver is to transmit torque and pressure to the casing and casing shoe.
3. Casing
The top of the casing can be connected with the casing driver or other casings through the pins, and the bottom of the casing can be connected with the casing shoe or other casings.
4. Casing shoe
The cutting bits are inlaid on the bottom of the casing shoe, and various strata and rocks are cut around by rotating and downward pressure, which can slow down the resistance of the embedded casing and improve the drilling capacity of the casing.
5. Bolts
The conical rings and the thread rings are fixed on the casing. When every two casings are connected with each other, supporting rings shall be screwed into the thread rings and the conical rings with the sealing ring.

Application of pile casings:
1. Silt layer
When for the flowing plastic geology, it easily occurs that the pile diameter contracts because of its high water content and low strength, which can cause hole collapse. At this time, casing technology is used to support the pile wall and prevent the hole collapse.
2. Loose formation
When the rotary drilling rig is working in loose geology with rich groundwater, casing technology can be adopted to prevent hole collapse and protect groundwater by supporting the hole wall.
3. Boulder with large size
When there are large size boulders, and it is easy to cause deviation of holes due to uneven geological hardness. If casing technology is adopted, it can be forced to guide through casing to prevent deviation of holes, and the casing shoe can pass through boulders.
4. Non-filling karst cave
When drilling into non-filling karst cave with large volume, the mud will be lost in a moment, and the mud pressure and wall protection will be lost at the upper part of the pile. If it is loose geology, the hole will collapse; meanwhile, the hole deviation will be caused if there is non-filling karst cave without hole wall guidance. Casing technology is adopted to prevent hole collapse and deviation through casing protection and guidance.
6. Inclined pile
Some foundation engineering piles need not only axial bearing capacity, but also lateral support capacity, such as offshore drilling oil platform, port drilling pile, etc. when rotary drilling rig is constructed in inclined pile, it must be constructed under the guidance of casing, otherwise it is difficult to form holes or even cause damage to parts.
***The casing technology supports the hole wall to prevent hole collapse and avoid groundwater immersion and benefit guidance, and greatly improves the piling quality. It not only meets the environmental protection requirement of city construction, but also suits the field construction requirements.
- Main material: Q355B or 25CrMo from the top steel manufacturer in China.

Casing technology
1. Casing driver
Through the connection of power head with casing adaptor, casing driver, casing and casing shoe, torque and pressure are transferred to casing and casing shoe. The drilling process alternates between casing drilling and drilling tool taking out the soil for lower resistance of casing drilling.
2. Oscilator
Oscilators are applied for larger piles or longer casings against greater resistance. One end of the oscilator is fixed on the chassis of the rotary drilling rig, and the clamp of the oscilator holds the casing tightly. Then the left and right rotary cylinder push the casing rotating repeatedly and raising or pushing down the casing to finish the drilling process.3. Vibrating hammer
The crawler crane lifts the vibration hammer, the hydraulic clamp at the bottom of the vibration hammer holds the top of the casing. The vertical vibrating force of eccentric wheel acts on the casing to drill into the hole or pull out from the hole.
