Anti-infiltration foundation pit peripheral slope crest water interception and drainage construction process
The invention discloses an anti-infiltration foundation pit peripheral slope crest water interception and drainage construction process, which belongs to the field of slope support construction, and comprises the following steps: according to a general plane excavation arrangement diagram, arranging a concrete temporary road according to an annular foundation pit, arranging an exposed corrugated pipe intercepting ditch on the inner side of the road, keeping the distance from the intercepting ditch to a slope crest edge line by 1m, and trimming the ground surface around the foundation pit. The slope top corner faces 5%-10% of the water drainage gradient of the intercepting ditch; well point dewatering is arranged around the foundation pit according to requirements; water collecting wells and drainage pipes are arranged on the road every 30-50 m, exposed corrugated pipe drainage ditches are arranged on the outer side of the road, and water is filtered and then discharged to a municipal pipe network. It is effectively guaranteed that surface water is discharged in time and does not permeate into the foundation pit or the underground, slope rainwater washing is reduced, the stability and safety of the foundation pit can be effectively guaranteed, the safety of the foundation pit is guaranteed, and sinking of a temporary road roadbed can be effectively controlled.
本发明公开了一种防下渗基坑周边坡顶截排水施工工艺，属于边坡支护施工领域，包括根据总平面开挖布置图，按照环形基坑设置混凝土临时道路，在道路内侧设置明敷波纹管截水沟，截水沟距离坡顶边缘线1m，修整基坑周围地表，坡顶转角向截水沟5％‑10％的排水坡度；井点降水按要求布置基坑周边；道路每隔30‑50m设置集水井、排水管，道路外侧设置明敷波纹管排水沟，过滤后排至市政管网。有效保证地表水及时排出，不向基坑内或地下渗入，减小坡面雨水冲刷，可以有效保证基坑的稳定性、安全性，确保基坑安全，且可以有效控制临时道路路基的下陷。
