Research on the Application of High Pressure Rotary Jet Pile Construction Technology in Deep Foundation Pit Support
In order to ensure the construction safety and bearing capacity of deep foundation pit support,this paper studies the application effect of high pressure rotary jet pile construction technology in deep foundation pit support by taking the water storage dam construction engineering of Heshui water plant in Genghe Town,Gaoming District as an example.Combined with the deep foundation pit support design scheme and the soil layer investigation re-sults,the construction process of high pressure rotary jet pile is determined,and reasonable construction equipment is selected.After the construction parameters are set,the construction of high pressure rotary jet pile is completed according to the construction standards.The analysis of the construction results shows that after the application of the construction technology,the maximum settlement value of the deep foundation pit support foundation is 30.5 mm,which meets the engineering standard.
