Construction Technology of Steel Pipe Pile Support for Deep Foundation Pit of Water Conservancy Engineering Building

文章主要从清除深基坑内淤泥积水、布置定位导向架、打入水利工程建筑深基坑钢管桩以及喷射浇筑混凝土四个方面设计水利工程建筑深基坑钢管桩支护施工方法,经过工程实例分析可以得到:该方法施工后最大形变量为1.8 mm,渗水量为0.01 m3/d,确保了基坑在施工和使用过程中的稳定性和安全性,显著降低了地下水对基坑施工和使用的影响。

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 positioning guide frame,driving steel pipe piles in deep foundation pit of water conservancy engineering building,and spraying and pouring concrete.After analyzing the engineering 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.
