Construction Technology of Steel Pipe Pile Support for Deep Foundation Pit of Water Conservancy Engineering Building
This paper mainly designs the construction method of steel pipe pile support for deep foundation pit of water conservancy engineering building from four aspects:removing silt water in deep foundation pit,arranging posi-tioning guide frame,driving steel pipe piles in deep foun-dation pit of water conservancy engineering building,and spraying and pouring concrete.After analyzing the engi-neering examples,it can be obtained that the maximum volume of deformation after the construction with this method is 1.8 mm,and the seepage amount is 0.01 m3/d,which ensures the stability and safety of the foundation pit in the process of construction and use,and significantly reduces the influence of groundwater on the construction and use of foundation pit.
