Casing is one if most import and commonly used equipment in deep foundation work，
it is wildly used in deep foundation/ bored pile/ drill shaft/ pillar construction work, 
to protect the shaft work safty.

Double wall casing 

Double-walled casings can be used universally, as they are designed especially

for transmitting high rotational and vertical forces as created by the KDK

rotary drives and oscillators.

The use of double-walled casings ensures a flush drill string.

Single-walled casings can be used for applications where weight reduction is Important

Casing drive adapter

transfer the torque from the rotary drive onto the top of the casing string

Casing shoes

Casing shoes are important key elements on a casing string, especially when working in hard soil conditions or when constructing secant pile walls. Cutting rings on the cutting shoe are supplied either with weld-on teeth or with replaceable cutting teeth.

Casing Drilling Technology Feature
1. Environment friend and safety pile drilling method (Drilling with All casing, no mud)
2. Widely used in different difficult formations where there is a risk of collapse or broken formation, such as quicksand, flowing and fictile soils, high pressure groundwater formations, gravel and detritus-type soils etc.
3. High quality cast in-situ pile and secant pile wall. Large pile sizes with high load capacity
The ability to penetrate substantial boulder layers and other obstructions
4. Socket into hard rock is possible
5. Permanent liners may be incorporated to protect pile shafts
6. Depths of up to 60m are attainable
Application
Foundation pile, Secant pile wall, Remove of abandoned foundation pile and barrier, river bridges and marine structures.
