摘要
Abstract
Combined with the actual foundation replacement project of an industrial plant in western China,this paper expounded that pit-jacked steel pipe static pressure pile in virtue of its superior engineering performance can effectively solve the diseases caused by foundation settlement of existing building.It proposed the treatment scheme of underpinning reinforcement of foundation by large diameter pit-jacked steel pipe static pressure pile,together with the scope of application,the principles of design,the main parameters and their selection;and then analyzed the construction technology,the key points of construction to be controlled and the quality control measures.According to the supervision data and the service condition,the reinforcement effect was evaluated.It shows that large diameter steel pipe static pressure pile contributes to reliable reinforcement effect,and is worth wide use.关键词
