Tunnel type water disposal device

Abstract

The utility model relates to the field of hydraulic engineering. The essence of the utility model is that in a tunnel-type irrigation device consisting of a supply channel, an inlet section, an adjacent irrigation tunnel and a lower by-pass, according to the utility model, a spherical plate with holes is fixed to the side walls of the tunnel, which allows maintaining the air flow in the upper part of the tunnel and preventing the formation of waves from the opposite side. In the proposed design, the water flow through the tunnel is regulated along the length of the tunnel by a spherical plate with holes fixed to the side walls of the tunnel, preventing the formation of waves, and also ensuring the normal outflow of water from the tunnel. This reduces the risk of erosion and washing away of the opposite bank of the river, thereby increasing the strength and stability of the tunnel.
