Problems solved by technology

However, when there is no water outside the flood wall, it is in a flat state, which cannot form a courtyard wall, and when the wall is in a horizontal state, it takes up a large space, so it is not suitable for a courtyard wall flood control wall.

Embodiment Construction

[0011] Such as figure 1 , figure 2 As shown, a kind of double-layer flood wall that provides water floating source power by rubber airbags is realized in the following way: the upper floor flap has an upper beam 12, a middle beam 13, and a lower beam 14 (there is a protruding line along the bottom of the lower beam) part, together with the groove and rubber of the foundation wall to form a water-stop device), the beam lattice system composed of multiple longitudinal beams 15 and cross beams 17 is welded with the steel material panel 11, and the two sides of the upper flap are connected by layering strips and bolts Install the rubber waterstop 18, and connect it with the adjacent flap through the rubber waterstop and the bolt buckle, install the panel pull ring 4 on the upper part of the panel to fix the cable, and the other end of the cable is connected to the embedded part. The upper flap and the reinforced concrete are connected by a rotating shaft, and a water-stop device...

Abstract

The invention relates to a double-layer flood protection wall using an inflating airbag as a power to automatically lift a turnover plate, belonging to the technical field of hydraulic engineering. The double-layer flood protection wall is mainly formed by connecting the inflating airbag (1), a steel plate (3) of the turnover plate, a connection rotating shaft (7), an automatic inflating device (8), a flexible pull rope (5), a reinforced concrete base wall body (9), a water stopping device (10), a water stopping device (18) and serial buckles among the plates, wherein the lifting of an upper plate is controlled by buoyancy force provided by the air inflation or deflation of the airbag. The invention has the advantages that the double-layer flood protection wall is capable of resisting against the flood at different levels, has light and thin plate, can automatically lift, is convenient to use and has a certain economic benefit, so that the double-layer flood protection wall can be widely applied to the flood prevention project of cities and important buildings.

Description

technical field [0001] The invention belongs to the field of hydraulic steel structure or water conservancy and hydropower engineering. Specifically, a self-floating novel double-layer flood wall is provided. Background technique [0002] Flood control wall is one of the main structural types of flood control in urban river sections, and it is also a common structure type for flood control of important facilities such as factories, schools, and high-voltage substations outside the urban flood control area. Its top elevation should be the flood level that meets the fortification standard plus some safety superelevation. This height is often much higher than the usual water retaining height or general building height. If the flood wall is built at this height, it will affect the surrounding areas on the one hand Landscape, on the other hand, there are few opportunities to use the upper wall, and the construction cost is relatively high. In order to increase the variable heig...
