Advantages

1 Suitable for a wide range of strata, especially complex formations.

2 Easy to control in case of settlement and displacement. Can be constructed near buildings and underground pipelines.

3 High verticality, good quality walling.

4 With the protect of steel casing ,the walls are free of collapse, no vibration, minimized disturbance to the surrounding buildings, safe construction.

5 Construction in karst formation with casing rotator,Avoiding risk of collapse,buried drilling, and stuck drilling tools due to the use of full casing.
