Application of High Pressure Jet Grouting Pile in Trenching Construction of Concrete Diaphragm Wall

According to the analysis of high pressure jet grouting pile and trenching mechanism of concrete diaphragm wall,by referring to the complex structural characteristics of the stratum in which concrete diaphragm wall is constructed,It is proposed to use high pressure jet grouting pile to reinforce soil body,then excavate trench to pour concrete diaphragm wall in a certain construction area,which resolves the technical difficulty about the trenching of concrete diaphragm wall in soft soil stratum.In addition,the technical essentials and construction effect of high pressure jet grouting pile reinforcing soft base are introduced with the detailed project case.
