Plugging structure of dewatering well in sump of foundation slab and construction method of plugging structure
According to the blocking structure of the dewatering well in the sump of the foundation slab and the construction method of the blocking structure, a closed joint of the dewatering well is moved upwards into the sump of the foundation slab, the situation that the dewatering well is soaked in underground water for a long time in the later period is avoided, and the risk of corrosion leakage is reduced; the plugging sleeve of the well plugging structure adopts a composite plugging mode of a gravel layer, a concrete layer and an asphalt paste layer, so that the plugging efficiency of the dewatering well is improved. The problem that leakage hidden danger exists in a conventional precipitation well sealing method is solved.
本发明公开了一种基础底板的集水坑内降水井的封堵结构及其施工方法，将降水井的封闭节点上移至基础底板的集水坑中，后期避免长期浸泡地下水中，降低了腐蚀渗漏的风险，封井结构的插接套管采用碎石层、混凝土层和沥青膏层的复合封堵方式，提高了降水井的封堵效率和封堵效率。本发明解决了常规的降水井封井方法存在渗漏隐患的问题。
