The invention discloses a flood storage waterlogging prevention device capable of increasing the urban river channel
water storage. The flood storage waterlogging prevention device is located on a river channel
revetment which comprises multiple sections of hollow structure. Each section of hollow structure is a section of
water storage body. Each
water storage body is divided into a plurality of water storage box bodies through partition wall structures in the direction of the river shoreline. Every two adjacent water storage box bodies are communicated through a communicating door hole. A water inlet is formed in the upper portion of the side, close to a river, of each water storage box body. The bottommost end of each water inlet is lower than the highest
water level of a river channel. A plurality of check valves are arranged at the bottom of the side, close to the river, of each water storage box body. The check valves and the lowest
water level of the river channel are located on the same horizontal line. The top faces of bottom plates of the water storage box bodies are lower than the lowest
water level of the
water channel. By means of the flood storage waterlogging prevention device, the flood storage capacity of the river channel is effectively increased, the runoff and the
peak value of storms are decreased and delayed, and therefore the
flood control capacity of the river channel is improved. The flood storage waterlogging prevention device is simple, practical, safe, reliable, capable of saving investment, free of power, free of manual operation and capable of automatically storing water and emptying in a circulating mode.
