Double-layer anti-flood wall

Abstract

The invention discloses a double-layer anti-flood wall. The double-layer anti-flood wall comprises a concrete foundation wall body. An overturn plate steel deck is arranged on the top of the concrete foundation wall body. The overturn plate steel deck is connected with the concrete foundation wall body through a connecting rotary shaft. A 45-degree included angle is formed between the concrete foundation wall body and the overturn plate steel deck. The bottom of the concrete foundation wall body penetrates through a steel plate and is connected to the upper surface of an expanding material layer through an embedded part. A hard material layer is arranged on the lower surface of the expanding material layer. A filling material layer is arranged on the lower surface of the hard material layer. The filling material layer, the hard material layer and the expanding material layer are combined into an integrated connection structure. The steel plate is provided with a first metal fastener and a second metal fastener. The double-layer anti-flood wall is good in flood prevention effect, can resist floods with different water levels, and is quite convenient to install and use, stable in connection performance and large in impact bearing capacity.

Description

technical field [0001] The invention relates to a flood control wall, in particular to a double-layer flood control wall. Background technique [0002] Flood control canal is one of the main structures for flood control in urban river sections, and it is also a common structure for flood control of important facilities such as factories, schools, and high-voltage substations outside the urban flood control area. The height of the top of the flood wall 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, on the one hand, it will affect Surrounding landscape, on the other hand, there are few opportunities to use the upper wall, and the construction cost is relatively high. Therefore, some flood control walls are assembled, but the flood control strength of this type of flood control wall is no...

Problems solved by technology

The height of the top of the flood wall 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, on the one hand, it will affect The surrounding landscape, on the other hand, there are few opportunities to use the upper wall, and the construction cost is relatively high

Therefore, some flood control walls are assembled, but the flood control strength of this type of flood control wall is not high, and they need to be supported by dykes to maintain stability, and some are made of flood control sandbags. Large, not recyclable, easy to leak or collapse
