Technical Field

The invention belongs to the technical field of flood control equipment at an entrance and an exit of an underground space, and particularly relates to a louvered flood control wall.

Background

In recent years, rainstorm weather is frequent and abnormal rainfall is excessive, an alarm clock is sounded for flood prevention work in China, and once urban areas encounter overlarge rains due to rainfall runoff process change caused by urbanization construction, insufficient urban flood drainage capability and the like, the waterlogging is frequent. The safety of lives and properties of people and the effective operation of urban underground facilities are seriously threatened. In the face of the situation, the traditional method for flood control is to use sand bags and wood boards to block the inflow of rainwater, but the sudden attack of rainstorm cannot be as early as finding flood control articles such as sand bags and the like, sometimes even in the middle of the night and in rest days, and the attack cannot be as early as the organization personnel to perform flood control and blockage control, so that the life and property safety of people are threatened. In addition, when heavy rainstorm occurs in China, the phenomenon that underground spaces such as a residential underground garage or a basement are submerged always occurs, so that a large number of vehicles or important articles are submerged by the rainwater, and great economic loss is brought to people. For natural disasters caused by the rainstorm, some communities can emergently deploy sandbag flood protection walls or adopt flood protection fences and the like to prevent low-lying areas from being flooded by water when the rainwater is increased to a certain degree. However, these facilities are inconvenient to arrange in the rain, prevent the normal use of the road if they are arranged in advance, and require manual removal after heavy rain, which is time-consuming and labor-consuming.
