Research and Application of Mini-sized Steel Pipe Pile Technology in Limited Space

Mini-sized steel pipe pile technology is more used to foundation reinforcement, underpinning and isolation under the condition of construction site or space is limited.This paper discusses the mechanism and construction technology of mini-sized steel pipe grouting pile foundation underpinning technology. This paper shows how to effectively solve the problems of existing buildings foundation reinforcement construction through the actual engineering examples. This paper also analysis of the feasibility and validity of the mini-sized steel pipe grouting pile foundation underpinning technology, the research results can provide a practical and feasible construction scheme for similar engineering.
