Flood drainage system blockage structure with underground spring water and tailing seeping water drainage function
A flood drainage system blockage structure with an underground spring water and tailing seeping water drainage function comprises an upstream blockage structure and a downstream blockage structure. The upstream blockage structure comprises a chute, gaps are reserved between cover plates of the chute, the gaps are filled with non-woven geotechnical cloth I, and a concrete block is arranged at the inlet section of the chute. The downstream blockage structure comprises a culvert pipe, a concrete retaining wall is arranged at the outlet end of the culvert pipe, a concrete cover plate is arranged above the concrete retaining wall, a cement mortar plastering layer is arranged on one side face of the upstream side of the concrete retaining wall, and the concrete retaining wall is provided with an observation hole, an overflow hole and a sand washing hole; a grit chamber is arranged on the upstream side of the concrete retaining wall, a water passing area is located on the grit chamber, a concrete bottom plate is arranged at the bottom of the grit chamber, and the upper surface of the concrete bottom plate is a bevel. A second geotechnical cloth plug is arranged in the overflow hole, and a first geotechnical cloth plug is arranged at the inlet end of the sand washing hole. According to the flood drainage system blockage structure, flood cannot pass, but underground spring water and tailing seeping water can pass, no sand is leaked, construction quantity is small, cost is low, and construction period scheduling is flexible.
