Construction method of rain sewage pipeline deep foundation pit on road
The invention relates to the technical field of foundation pit construction, and discloses a construction method of a rain sewage pipeline deep foundation pit on a road, which solves the technical problem of how to excavate a pipeline deep foundation pit to reduce the influence of excavation surrounding ancillary facilities in the prior art, and comprises the following steps: (1) area measurement and lofting; (2) intelligent precipitation construction is conducted, specifically, an intelligent precipitation system is adopted and combined with a well-point precipitation method, and water pumping and precipitation are conducted on underground water in the to-be-excavated area; (3) steel sheet pile construction is conducted, specifically, the depth of the foundation pit exceeds 5 m, Larsen steel sheet pile supporting construction is adopted in a sloping limited area, two inner supports and two surrounding purlins are adopted in each steel sheet pile, and the foundation pit is excavated in three layers; (5) 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 (6) pipeline closed water test construction: checking the pipeline, and then filling the pipeline with water for test. According to the technical scheme, the invention provides the construction method of the rainwater and sewage pipeline deep foundation pit on the road.
本发明涉及基坑施工技术领域，其公开了一种公路上雨污水管道深基坑的施工方法，解决了现有技术中如何对管道深基坑进行开挖而减小开挖周围附属设施影响的技术问题，包括以下步骤：(1)区域测量、放样；(2)智能降水施工：采用智能降水系统并结合井点降水法，对待开挖区域的地下水进行抽水降水；(3)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；(5)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；(6)管道闭水试验施工：检查管道，然后将管道充水进行试验。根据以上技术方案，本发明提供一种公路上雨污水管道深基坑的施工方法。
