HU XIAOLONG / XIONG HAIBIN / PENG WENXIANG / SUN SHUHAO

The invention discloses a novel inverted filter trunk. The polygonal trunk comprises a polygonal trunk frame, a polygonal trunk outer wall and an inverted filter material, the polygonal trunk frame is arranged on the periphery of the pipe gush water outlet; the polygonal trunk outer wall is arranged on the polygonal trunk frame; the inverted filter material is arranged in an area enclosed by the polygonal trunk frame and is positioned on the inner side of the outer wall of the polygonal trunk; the polygonal trunk frame comprises vertical supporting stand columns, transverse connecting rods and connecting pieces. The vertical supporting stand columns are fixed to the periphery of the pipe gush water outlet at intervals, and the transverse connecting rods are connected among the vertical supporting stand columns through connecting pieces. The polygonal trunk outer wall comprises a plurality of net-shaped filter layers; and the net-shaped filtering layer is arranged on the vertical supporting stand columns and the transverse connecting rods. The device has the advantages of being easy to install, capable of being rapidly assembled, expandable and capable of effectively discharging water pressure. The invention further discloses a rapid construction method of the novel inverted filter trunk.
