Study On Deep Foundation Pit Support Scheme Of No.8 Rainwater Pump Station In Tianjin Lingang Industrial Area

Combined with the practice of Lingang Industrial Zone No.eight rain water pump station project,detailed analysis of the design of foundation pit supporting scheme.The project is located in Lingang Industrial Zone,north of the Yellow River is about 34 m,the other side of open space,the depth of 10 m,the main characteristics of foundation pit excavation is trapezoidal,excavation depth,complex geological conditions,excavation site safety or not has great social influence.The slope excavation unloading soil and pile + dense row of I-steel supporting ring single supporting system.(1)Analyzes the characteristics and technical difficulties of this excavation project,select the appropriate support system solutions for the foundation pit engineering;(2)According to the background of the foundation pit support engineering,this paper summarizes the various theories and methods of the calculation and analysis of the foundation pit engineering;(3)To support the structure of the design calculation,engineering design and calculation of the precipitation,support analysis and calculation to verify the stability of foundation pit support;(4)Through the construction of the foundation pit,precipitation,rescue and monitoring of all aspects of a comprehensive exposition.
