Flood storage waterlogging prevention device capable of increasing urban river channel water storage

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a flood storage and waterlogging prevention device for increasing the water storage capacity of urban rivers. Background technique [0002] Water system is one of the important elements of urban natural environment, and its quantity and quality changes are the result of long-term interaction between nature and human activities. With the deepening of urbanization, many rivers are buried, silted up or die naturally, the number of rivers is greatly reduced, and the water area is greatly reduced. , the urban area was flooded and the traffic was paralyzed. Urban flooding is now a "nightmare" that occurs almost every year for cities. After a heavy rainfall, the streets became rivers, houses flooded, cars sank, and river water flooded basements... More frequent urban waterlogging had a huge impact on people's lives, economic development and the normal operation o...

Problems solved by technology

According to domestic and foreign surveys, there is no precedent for adding regulation and storage devices to the river without changing the land use of the river, without changing the function and scale of the river.
