Seepage backwater well for dry method yard

The utility model relates to a seepage type back-up water well for tailings reservoirs, in particular to a seepage type back-up water well adapted for dry red mud yards and dry tailings reservoirs. The structure is that the utility model employs steel pipes with pores as well body, and adds stiffening ribs outside the well body, water discharging layers formed by stones are stacked outside the well body in layers, and the lower end of the well body is connected with the well foundation which is connected with a horizontal pipeline. The seepage type back-up water well of the utility model can not only collect adhesive fluid of tailings, but also discharge yard rain timely, efficiently collects adhesive fluid of 'dry' tailings. The back-up water is clear and no cicatrisation appears on the steel pipe wall. The in-section construction can reduce influence of a large amount of wind load to the back-up water well, thereby the construction cost is saved, the heightening process is simple and on site construction is
