Telescopic automatic river levee for controlling flood by means of flood

Abstract

The invention provides a telescopic automatic river levee for controlling flood by means of the flood, and belongs to the technical field of building of movable river levees. According to the technical aim, levee wall plates with no flood control function yet are assembled into a levee body with a flood control function by means of impact force, pressure and buoyancy of the flood. For achieving the technical aim, a levee foundation on a riverway is adopted, a plurality of limiting piers are arranged beside the levee wall surface connected with sealing pieces above the riverway, an upper floating preventing block is mounted on the upper portion of each limiting pier, and space between the levee wall surface and the limiting piers allows the multiple levee wall plates fixedly connected withbuoys to slide up and down. Lower floating preventing blocks are mounted on the lower portions of the levee wall plates. The multiple levee wall plates are connected through flexible structures to form the telescopic automatic river levee for controlling the flood by means of the flood. When flood emerges, the levee wall plates can stretch out of the levee foundation and become the flood control levee body, the levee body rises when water rises, and the levee body falls when the water falls.

Description

(1) Technical field [0001] The invention relates to a telescopic automatic embankment for flood control, and belongs to the technical field of movable embankment construction. (2) Background technology [0002] River dikes are water-retaining structures along the river, mostly built with earth and rocks, and the project is huge. The river embankment located in the river transition zone is the main form of water conservancy engineering to prevent flooding in the lower reaches of the river, and the flood control effect is very significant. In recent years, some supporting facilities for embankments have emerged, such as integral hinge movable dams, portal hydraulic gates, and flip-type movable dams. Although these existing technologies show the mechanization trend of dikes, they still occupy a lot of land. The dam body is above the ground, the project is huge, and a large number of hydraulic facilities need to be configured, which has disadvantages such as high energy consumpt...

Problems solved by technology

In recent years, some supporting facilities for embankments have emerged, such as integral hinge movable dams, portal hydraulic gates, and flip-type movable dams. Although these existing technologies show the mechanization trend of dikes, they still occupy a lot of land. The dam body is above the ground, the project is huge, and a large number of hydraulic facilities need to be configured, which consumes a lot of energy and has high construction costs.

These dams also occupy a large amount of land and require a large amount of earthwork, which is not conducive to the protection of farmland and the environment, affects the water and air cycle balance of the city and its surrounding environment, affects the cultural landscape, and weakens the comprehensive functions of the city
