Floating automatic river levee for preventing flood with flood

Abstract

The invention relates to a floating automatic river levee for preventing flood with flood and belongs to the technical field of movable river levee construction. The invention aims to solve the technical problem that the river levee wallboards form a levee body with a flood-preventing function by means of impact force, pressure and buoyancy of flood. In order to solve the technical problem, a plurality of limiting piers are arranged next to a levee foundation wallspace, connected to a seal member on the upper portion, of a riverway in the direction of a levee foundation on the riverway, a plurality of floating levee wallboards can vertically slide up and down along the wallspace between the levee foundation wallspace and the limiting piers, upper floating limiting blocks are mounted on theupper portions of the limiting piers, lower floating limiting blocks are mounted on the lower portion of the floating levee wallboards, and the plurality of floating levee wallboards are connected byflexible structures to form the floating automatic river levee for preventing flood with flood. When flood comes, the floating levee wallboards can float up below the levee foundation surface to extent to become the flood-preventing levee body, and when the water rises, the levee is raised; and the water falls, the levee falls.

Description

(1) Technical field [0001] The invention relates to a floating 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 consumptio...

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
