Forward pumping and draining facility for accumulated water in toe board downstream foundation pit and construction method of forward pumping and draining facility
The invention relates to a forward pumping and draining facility for accumulated water in a toe board downstream foundation pit and a construction method of the forward pumping and draining facility.According to the technical scheme, a water collecting structure is arranged in the toe board downstream foundation pit of a concrete face rockfill dam and connected with a drainage steel pipe; the drainage steel pipe extends out of a downstream dam body of the concrete face rockfill dam; a water pump is installed on the drainage steel pipe; the water collecting structure is provided with a water collecting tank and a reinforced concrete box, wherein the water collecting tank is excavated in the design face of the toe board foundation pit and arranged parallel to a toe board, and the reinforcedconcrete box is located below the water collecting tank; a water collecting pit communicating with the water collecting tank above the reinforced concrete box is formed above a top plate of the reinforced concrete box; a plurality of drainage holes communicating with the water collecting pit and the interior of the box are formed in the top plate of the reinforced concrete box; and the bottom ofthe reinforced concrete box is connected with the drainage steel pipe. The forward pumping and draining facility is suitable for concrete face rockfill dam engineering.
本发明涉及一种趾板下游基坑积水正向抽排设施及其施工方法。本发明的目的是提供一种趾板下游基坑积水正向抽排设施及其施工方法。本发明的技术方案是：一种趾板下游基坑积水正向抽排设施，在混凝土面板堆石坝的趾板下游趾板基坑内设有集水结构，集水结构连接排水钢管，该排水钢管延伸至混凝土面板堆石坝下游坝体外，排水钢管上装有水泵；集水结构具有开挖形成于趾板基坑设计面上且平行趾板设置的集水槽，以及位于集水槽下方的钢筋混凝土箱体，钢筋混凝土箱体顶板上方形成有与上方集水槽连通的集水坑，钢筋混凝土箱体的顶板上开设有若干连通集水坑和箱体内部的排水孔，钢筋混凝土箱体底部连接排水钢管。本发明适用于混凝土面板堆石坝工程。
