Application of Steel Pipe Pile Joined with Large Diameter Pile in Slope Support

Abstract:

It is very difficult to the construct large diameter anti-slide pile in hard rock mass, the safe and effective structure design and reasonable selection of construction methods are necessary. Taking a case of foundation pit supporting engineering, with innovative supporting structure scheme, using micro steel pipe piles instead of large pile in hard rocks, and these improved technology effectively overcame the difficulties in large diameter rock-socketed pile construction and met the requirements of original design to achieve the supporting effect.

Key words:anti-slide pile; steel pipe pile; pile group; large diameter pile; slope support
