Construction Technology of Deep Foundation Pit Foundation Soil Reinforcement of Sewage Storage Tank
In order to cope with the problems of sewage overflow and initial rainwater pollution in Zhuyuan area and improve its sewage storage capacity,a new storage tank at 500,000 m3 and supporting facilities are built.In order to meet the requirements of large storage tank volume and small site area,deep foundation pit engineering is adopted,and foundation soil reinforcement technology is often used for deep foundation pit in soft soil area.This paper mainly discusses the application of triple pipe high-pressure rotary churning pile and RJP process pile in deep foundation pit foundation soil reinforcement construction of sewage storage tank,which can effectively isolate the confined aquifer and reduce the impact on surrounding environment.For the passive zone,the reinforcement construction technology can also better improve the mechanical properties of the soil,and plays an important role in the deformation and stability of the enclosure structure.
