Drainage structure for flood prevention

Abstract

The invention discloses a drainage structure for flood prevention. The drainage structure comprises two river levees arranged on the two sides of a river channel; flood discharge channels are arranged on the sides, away from the river channel, of the two river levees; flood discharge openings are formed in the two river levees; the two flood discharge openings communicate with the river channel and the flood discharge channels; barrier plates are arranged in the two flood discharge openings in a sliding mode; the barrier plates are made of novel rubber formed by mixing polyurethane resin and iron particles with the diameter of three micrometers; winding mechanisms corresponding to the barrier plates are arranged in the river levees; and magnetic field generating devices corresponding to the barrier plates are further arranged in the two river levees. When flood outbreaks, the flood discharge openings can be automatically opened through the change of the water level of the river channel, so that the water level of the river channel is controlled, the problem that the water level of the river channel is too high to cause levee failure is effectively avoided, and the influence of the flood on the property safety of residents along the bank is avoided.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a drainage structure for flood control. Background technique [0002] Flood refers to a river, ocean, lake, and other water bodies that rise above a certain water level, threatening the safety of the relevant area, or even causing disasters. It is usually caused by natural factors such as heavy rain, rapid ice melting, and storm surge. Rapid increase, or a natural phenomenon in which the water level rises rapidly, is a natural disaster. When a flood breaks out, due to the rapid increase in water level and the erosion of the river banks on both sides, the problem of embankment bursting often occurs, which seriously affects the property of residents on both sides of the river. Safety. [0003] In the prior art, when responding to flood outbreaks, artificial flood control sandbags are usually added to the embankments on both banks to increase the height of the...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the shortcomings in the prior art, such as: the traditional river bank flood control often adopts the method of adding sandbags for flood control, which is inefficient and labor-intensive, and proposes a method for flood control and flood control drainage structure
