Deep Foundation Drilling Casing Tube Casing Driver For Piling
Foundation
Advantage
1. The casing pipe is supported by the strength of the steel
casing, so as to prevent the hole from collapsing.
2. The application of occlusive pile technique in the foundation
pit protection is mainly due to the forced guide and lateral
support.
3. Applicable layers: complex flow sand, thick silt, loose fill,
large thick pebble, karst cave and so on.

BJTUFF drilling casing items adopt the high-carbon steel and
special welding method to keep the drilling strength and
efficiency.
Rotary Casing Pipe is obtained by driving a steel soding into the
ground in order to protect the whole drilling operation; basically
the rotary drilling tool during the working process, performs
inside a mechanical protection made by the casing fixed into the
ground.
Application
Double walled rotary casings pipe can be used universally, as they
are designed especially for transmitting high rotational and
vertical forces as created by the rig rotary drives or
oscillations. The use of double walled casing ensures a flush drill
string.
Single walled rotary casings pipe can be used for applications
where weight reduction is important.
