Construction method of self-overturning and self-supporting type automatic river levee

Abstract

The invention relates to a construction method of a self-overturning and self-supporting type automatic river levee and belongs to the technical field of movable river levee construction. The automatic river levee, the top of foundation of which is aligned to the ground, is constructed on a bent river bank. A construction method of a levee wallboard constructed along the river bank, a portal framefor placing the levee wallboard, an organic flexible water resisting material on an upstream face of the levee wallboard and a limiting reinforcing pier and a corner pier after the levee wallboard isoverturned is adopted, wherein a self-overturning mechanism and a self-supporting mechanism which are connected by a flexible structure are arranged on the foundation of the levee, the top of which is aligned to the ground. The levee wallboard is a pavement of a sidewalk road when no flood is available. When the flood comes, the levee wallboard can follow a flow of water to overturn automaticallyto be assembled to a firm levee body where water is unlikely to seep and leak. The levee and the pavement are compatible. When the water raises, the levee appears; and when the water falls, the leveeis hidden to form the pavement.

Description

(1) Technical field [0001] The invention relates to a construction method of a self-turning self-supporting slab type automatic river embankment, which belongs to the technical field of movable river embankment construction. (2) Background technology [0002] River dikes are water-retaining structures along the river. Most of them are flood control dikes made of earth, stone and reinforced concrete. The engineering is huge. The river embankment located in the river transition zone is the main form of water conservancy engineering to prevent flooding in the downstream of the river. In recent years, assembled flood walls and supporting facilities for some embankments have appeared. For example, assembled flood walls have been widely used in Europe. They have been used for many years in the Czech Republic, Austria, Germany, Slovakia, the Netherlands and other countries. In the use of assembled flood walls, integral hinge movable dams, portal hydraulic gates, and flap-type movab...

Problems solved by technology

In recent years, assembled flood walls and supporting facilities for some embankments have appeared. For example, assembled flood walls have been widely used in Europe. They have been used for many years in the Czech Republic, Austria, Germany, Slovakia, the Netherlands and other countries. In the use of assembled flood walls, integral hinge movable dams, portal hydraulic gates, and flap-type movable dams, although these existing technologies show the mechanization trend of dikes, they still occupy a lot of land and the dam body is higher than the ground. The project is huge and requires a large number of hydraulic facilities, which consumes a lot of energy, uses a lot of labor, and has disadvantages such as 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
