Combined type flood discharge and water taking method and structure thereof
The invention discloses a combined type flood discharge and water taking method and structure. According to the structure, flood discharging hole structures and water taking hole structures are arranged in the longitudinal direction in an overlapped mode along the center line of the flood discharging hole structures and the water taking hole structures, so that a flood discharging structure and a water taking structure are combined closely. At least one layer of flood discharging holes are formed in the longitudinal direction in the overlapped mode, water inflows in the depth direction of a riverway on a horizontal plane, and water inflows in a layered mode on the vertical plane, so that the problem that the horizontal space of a valley area is narrow and accordingly water taking is difficult is solved, and the flood discharging efficiency of longitudinal layered water inflow can be improved to the greatest extent. A horn-shaped port is formed in the front portion of each layer of flood discharging holes. A water gate is arranged in the middle of each layer of flood discharging holes for flood discharging control and can be closed when emergencies happen. A side ventilating hole is formed in the rear portion of each gate and used for supplying air during flood discharging, and the cavitation erosion problem caused by high-speed water flow is solved. By means of the method and structure, the horizontal layout space can be saved to the greatest extent; due to the fact that the flood discharging holes are located under the water taking holes, the sand flushing effect is good, the sedimentation phenomenon in front of the water taking holes is avoided, and normal water taking is guaranteed. In addition, opening and closing equipment is arranged in a concentrated mode, and operation and maintenance management are facilitated.
