Liftable flood control river levee and method

Abstract

The invention relates to a liftable flood control river levee and a method. According to the technical scheme, a river levee framework is arranged in a river levee, transition connecting steel bars are arranged in a concrete foundation, a rubber protection layer is arranged on the upper side of the concrete foundation, levee overflow protection rubber is arranged in a cavity formed in the rubber protection layer, and the lower end of the levee overflow protection rubber is movably connected with the top of the concrete foundation through fixing bolts; and an outside-levee flood discharge device is further arranged in the river levee, a flood discharge gate lifting cavity is formed in the river levee, the top of the flood discharge gate lifting cavity communicates with an outside-levee flood discharge channel, the outer side of the outside-levee flood discharge channel communicates with a plurality of flood discharge inlets, and the bottom of the flood discharge gate lifting cavity communicates with a river flood suction channel. The liftable flood control river levee and the method have the beneficial effects that the levee overflow protection rubber expands when encountering water to achieve rising, electric power is not needed, expansion can be achieved only after the levee overflow protection rubber encounters water, and therefore when the flood peak water flow is large, safe passing can be achieved, and the huge potential safety hazard that flood overflows the levee, and consequently the levee is broken is avoided.

Description

technical field [0001] The invention relates to a flood control embankment and a method thereof, in particular to a liftable flood control embankment and a method thereof. Background technique [0002] At present, on both sides of large rivers, there are generally multi-level protective embankments. The embankment of the river is an effective protection guarantee to avoid flood disasters, and can effectively protect the safety of residents and industrial and agricultural production in the basin during the rainy season. In order to control the destructive effect of the peak flow of the river on the hinterland of the river, flood embankments are often built along both sides of the river to avoid the possible harm caused by the flood flooding the embankment. For example, floods will cause changes in the ecological environment in the river basin, causing Changes, soil erosion, and land barrenness, etc., in severe cases, even destroy and destroy urban buildings, posing a huge thr...

AI Technical Summary

Problems solved by technology

The existing problems are: high production cost and complex structure, resulting in high cost, and cannot be fully extended to river embankments, and can only be applied to the reconstruction of local river embankments, such as the transformation and protection of key areas

The existing problem is: due to the very long length of the river embankment, the automatic flood wall used in this patent needs to be controlled by the controller to lift up and down, which will cause a problem, one is the construction cost of the long-distance installed automatic flood wall It is very high, and the self-weight of the automatic flood control wall is very large. The long-distance flood control wall requires a lot of hydraulic mechanisms to drive the lifting height. Second, the lifting of the automatic flood control wall requires the guarantee of electricity. However, in the rainy season, it is difficult to obtain electricity. , this will appear when the automatic flood wall needs to be raised, without power, it will not be able to realize the raising function it should provide
