Soil Cement and Steel Pipe Pile Method (HYSC Stake Method)

※HYSC : Hybrid-Steel Pipe and Soil Cement-Pile
A steel pipe with spiral-shaped ribs (ribbed steel pile) is laid in a soil cement column built in the ground to construct a foundation pillar. One type is to lay the steel pipe after having built the soil cement column, while the other type is to lay the steel pipe at the same time when the soil cement column is built, which can meet different conditions of construction.

Different types of HYSC pile
Features of Soil Cement and Steel Pipe Pile Method (HYSC Pile Method)
