Conveniently-cleaned gravel seepage layer, construction method and cleaning method
The invention discloses a conveniently-cleaned gravel seepage layer, a construction method, and a cleaning method. The seepage layer comprises a frame-type water-permeable layer and a vertical multifunctional well. An internal water inlet pipe and a gravel layer are built up in the water-permeable layer. An isolating layer hermetically connected with the water-permeable layer is arranged on the top of the gravel layer. When constructing, a covering layer is covered on the isolating layer. The lower end of the multifunctional well stretches into a fine sand water-bearing layer. The multifunctional well is formed by sequentially and fixedly connecting a precipitation pipe, a filter pipe and a solid pipe. The lower end of the filter pipe stretches into the fine sand water-bearing layer. The upper end of the filter pipe is located in the covering layer; and the upper end of the solid pipe extends above the horizontal line. A pump inlet pipe is arranged inside the solid pipe. When delivering water into the gravel layer, the water is pumped outside the multifunctional well, thereby forming a circulating water flow between the gravel layer and the multifunctional well, and accordingly discharging the blockage in the gravel layer. The seepage layer can be cleaned conveniently and timely, with the operability being strong and the operation cost being low, and accordingly directing the main development direction of future water environment treatment.
