Description

Dam flood blocking screen
Technical Field
The invention belongs to the technical field of flood control, and particularly relates to a dam flood control screen.
Background
Along with the aggravation of climate change and the increase of extreme weather times, rainstorm flood in China is correspondingly increased, for example, flood in the river basin of the Yangtze river in 2020 exceeds flood in the Yangtze river in 1998, so that province flood such as Hunan and Anhui overflows, numerous flood dams have dike-up situations, after the dike-up, flood floods a large amount of farmlands, and the national economic loss is serious.
At present, the social flood control department still has insufficient working efficiency for rescuing the dike after the dike burst, the water flow at the dike burst is turbulent and strong in impact force after the flood control dike burst, the dike burst can be quickly washed away by the water flow when only stones and sand bags are used for flood control, the existing related flood control and dike blocking facilities and equipment fall behind and are difficult to put into the dike burst under the influence of the water flow impact, and some flood control facilities can not be stably tied on a river bed due to poor stability when being put at the dike burst by the efforts of workers, so that the flood control facilities can be quickly washed away and submerged in flood, the time for delaying the water flow speed at the dike burst is too short, sufficient time can not be provided for the burying work of the stones, the sand bags and the subsequent sandy soil, and along with the development of climate change and the storm flood situation, effective flood control measures and efficient flood control technical equipment need to be researched in China.
Based on this, it is necessary to develop a dam flood barrier.
