When the strata conditions are unstable, Casing is required to be driven to overall depth to prevent hole's collapse.
It is called All Casing method (Benoto Method, Shaft Drilling).
To drive the Casing and retract it after concreting, Casing Oscillator is strongly recommended to use.
With its superior oscillating torque and lifting force, the machine shows the best performance of driving and retracting the casing.
If it is used together with Hammer Grab, it shows the fast excavating speed with its big volume of jaw and it is available for
excavating gravels and boulders layer.

Advantages of BUMA CE Casing Oscillator
▪ Flexible Sliding Box
When the oscillator is operated, much torque and force are
concentrated on oscillating cylinder’s rod and center rod.
Sometimes it causes too much stress on the parts and make them broken.
BUMA fl xible sliding box (patent) release the stress and provide stable and durable working condition.
▪ Remote Control
BUMA Casing Oscillator has 2 types of control, hydraulic manual control and remote control.
With this benefi if the remote control is out of order and urgently required to operate
the machine, it can be operated using hydraulic manual control.
▪ User-Friendly Maintenance
Casing Oscillator Method(Horizontal scroll)

|
|
|
1. Install starter casing equipped with cutting shoe. Add new casing section with bolted connection. |
2. Excavate soil continuously during casing installation. Maintain water head inside casing to balance external hydrostatic head at all times. |
3. Add new casing sections until pile has been excavated to depth. Keep casing tip ahead of excavation at all times. |
|
|
|
| 4. Install reinforcement cage and suspend at proper elevation. |
5. Pour concrete using sectional tremie pipe. Maintain concrete head above casing tip at all times. |
6. Remove casing and tremie pipe sections simultaneously as concrete is poured. |
