Construction method of rain sewage pipeline deep foundation pit on road
The invention discloses a construction method of a rain sewage pipeline deep foundation pit on a road. The construction method comprises the following steps that foundation pit excavation construction is conducted, wherein foundation pit excavation is conducted after measurement, positioning and lofting; the deep well point dewatering construction comprises the steps of surveying and setting out, drilling machine in place, slurry preparation, drilling and hole forming, pipe descending, filter material filling, well washing, drainage pipe arrangement and dewatering operation; light well point dewatering construction is conducted, specifically, the number of well point groups is determined according to the excavation perimeter of the foundation pit, then well point pipes are installed, and a drainage system is installed after well point pipe construction is completed; construction of Larsen steel sheet piles: the depth of the foundation pit exceeds 5 m, the Larsen steel sheet pile support construction is adopted in the sloping limited area, two inner supports and two surrounding purlins are adopted in the steel sheet piles, and the foundation pit is excavated in three layers; foundation pit protection construction is conducted, specifically, after the foundation pit is excavated, the periphery is protected through steel pipes, and a protective barrier is formed by assembling steel pipes; and performing pipeline closed water test construction. According to the construction method of the rain sewage pipeline deep foundation pit on the road, the stability of the foundation pit and the safety of surrounding structures can be guaranteed.
本发明公开了一种公路上雨污水管道深基坑的施工方法，包括以下步骤：基坑开挖施工：测量定位放样后基坑开挖；深井井点降水施工：测量放样、钻机就位、泥浆制备、钻进成孔、下管、填滤料、洗井、布设排水管、降水作业；轻型井点降水施工：根据基坑开挖周长确定井点组数，然后进行井点管安装，井点管施工结束后安装排水系统；拉森钢板桩施工：基坑深度超过5m，放坡受限区域采用拉森钢板桩支护施工，钢板桩内部采用两道内支撑，两道围檩，基坑分三层进行开挖；基坑防护施工：基坑开挖后四周采用钢管进行防护，防护栏杆采用钢管组装而成；管道闭水试验施工。该公路上雨污水管道深基坑的施工方法可以保证基坑稳定性及周边构筑物的安全。
