Background
When a flood disaster occurs, how to rapidly consolidate the dam is the key point for ensuring the property safety of people. The most original method for heightening the dam by stacking the sand bags has good stability, the heightened dam is stable and is not easy to be damaged by waves, but a large amount of manpower and material resources are consumed in the process of heightening and reinforcing, so that on one hand, the method is not economical, on the other hand, the time is urgent, the heightening speed cannot reach the water level rising speed, and the method still has practical dangerousness.
In order to heighten the dam rapidly, the flood control walls of some assembled types are mainly divided into two types, one type is the assembled flood control wall made of aluminum alloy, and the assembled flood control wall can meet the requirements of rapid disassembly and assembly, but is not stable enough and is easy to be destroyed by washing. The other type of flood protection wall is made of concrete, is prefabricated in advance and assembled on site, and has better stability relative to the first type of flood protection wall made of aluminum alloy, but the flood protection wall is heavy in weight, large in size, inconvenient to transport and complex to assemble on site.
According to the analysis, the stability and the dismounting efficiency are a spear shield body, the dismounting efficiency is improved to inevitably sacrifice the stability, the stability is improved, the inevitable volume and the inevitable weight are large, the dismounting is not convenient, and the technical scheme can not realize the consideration of the stability and the dismounting.

Detailed Description
For convenience of description, a coordinate system is now defined as shown in fig. 1.
As shown in fig. 1, an assembled flood protection wall includes a plurality of individual flood protection walls, and the individual flood protection walls are connected in sequence through a connection structure to form a continuous wall.
As shown in fig. 1, the flood wall unit comprises a foundation slab 1, a water retaining wall 2 with a wave-shaped curved surface is arranged on the foundation slab 1, a wave wall 3 is arranged at the rear side of the water retaining wall 2, and a water storage area is formed between the wave wall 3 and the water retaining wall 2.
As a specific implementation manner, in this embodiment, the height of the water retaining wall 2 is 1 meter, the height of the wave wall 3 is 2 meters, and the width of the water storage area is 0.6 meter.
As shown in fig. 6 and 7, first steel plates 31 are respectively disposed at the left and right ends of the wave wall 3, a second steel plate 5 is disposed between two adjacent wave wall 3 monomers, and the second steel plate 5 is respectively and fixedly connected to the rear end surfaces of the first steel plates 31 on the two flood wall monomers through screws.
Here, the first steel plate 31 may be fixedly connected to the wave wall 3 by expansion bolts, or may be fixedly connected to the wave wall 3 by pre-embedding.
Further, as shown in fig. 7, a rubber water stop strip 6 with a T-shaped cross section is arranged between the first steel plate 31 and the second steel plate 5, and a protruding portion of the rubber water stop strip 6 is clamped between the first steel plates 31 of two adjacent individual flood protection walls.
Further, since the distance error between the individual flood protection walls may be relatively large during assembly, in order to facilitate installation, as shown in fig. 7, an elastic compression hole 61 is formed on the protruding portion of the rubber sealing strip 6 to penetrate through the rubber sealing strip 6 in the length direction.
As shown in fig. 8, the wave wall 3 includes a front wall, a rear wall, a left wall and a right wall, both of which are planar structures, and both of which are wavy and symmetrically arranged. The front side wall, the rear side wall, the left side wall and the right side wall form a plurality of cavities together, and adjacent cavities are not communicated.
Thus, in the actual use process, when the front side wall of the wave wall 3 is impacted, the rear side wall not only can play a good supporting role, but also can effectively disperse the stress. Thereby improving the structural stability and impact resistance of the wave wall 3. In addition, due to the existence of the cavity, compared with the traditional solid wall body, the structure has lighter weight, is more economical, reduces the overall weight of the wave wall 3, and is favorable for realizing quick assembly and disassembly.
Further, in order to improve the stability and the impact resistance of the flood wall, as shown in fig. 2, fig. 3 and fig. 8, a plurality of vertically arranged connecting steel bars 4 are respectively arranged in the cavities at the two ends of the wave wall 3, concrete is poured in the cavities at the two ends of the wave wall 3, and the lower ends of the connecting steel bars 4 are embedded in the foundation slab 1.
As a specific implementation manner, in this embodiment, the wave wall 3 is made of concrete with a grade of C40, and the concrete poured into the cavities at the two ends of the wave wall 3 is made of a grade of C30. The connecting reinforcing steel bars 4 adopt phi 10 structure stressed reinforcing steel bars.
Further, in order to improve the stability and impact resistance of the flood wall, as shown in fig. 4 and 5, the two ends of the retaining wall 2 are respectively provided with a flow restriction portion 21 extending towards one side of the wave wall 3, and a gap with a certain distance is formed between the flow restriction portion 21 and the wave wall 3.
Thus, when the wave flower hits the wave wall 3, part of water will fall into the water storage area between the wave wall 3 and the water retaining wall 2, because of the existence of the flow limiting part 21, the water in the water storage area can not flow out from the water storage area quickly, when the water in the water storage area flows out of a small part, the next wave flower is hit again, and the water storage area can be filled up again. As shown in fig. 10, even if the water level of the river water does not reach the height of the water blocking wall 2, the water storage area can be always kept at a certain water amount, thereby improving the stability of the flood control wall.
In addition, through reserving the breach between current-limiting part 21 and wave wall 3, when the flood retreats, because this breach has between current-limiting part 21 and the wave wall 3, consequently need not artifical the water of depositing in the district of will depositing to take out, the water in the district of depositing can oneself flow out, after the water in the district of depositing completely flows out, dismantle flood wall and carry away can.
