[0002] As an important part of urban infrastructure construction, flood control dam construction plays an important role in ensuring the development of urban economy. Whether the flood control dam can meet the basic requirements of flood control work and whether it can play the role of resisting floods is related to the safety of people's lives and property and the stable development of urban economy. It is the responsibility of the water conservancy department to do a good job in the construction and maintenance of flood control dams. At the same time, flood control dams can improve the uneven distribution of water resources in the region, increase surface runoff, improve the regional microclimate, and also have a certain effect on eliminating the "heat island effect" of the city.

[0003] The main function of flood control dams is to effectively resist floods during flood seasons, protect the lives and property of downstream residents, and ensure normal production and life, which is of great significance to regional economic development. However, after the flood, it is inevitable that dams in some areas will be damaged, causing breaches and flood disasters. Therefore, how to quickly seal the breach has become a problem that needs to be solved urgently.

[0004] Therefore, those skilled in the art provide a rapid repair structure for flood control dams to solve the problems raised in the above background technology. Summary of the invention

[0005] The purpose of the present invention is to provide a rapid repair structure and method for flood control dams, which can quickly seal breaches and reduce disaster losses, so as to solve the problems raised in the above-mentioned background technology.

[0013] 1. This application can quickly seal breaches and reduce disaster losses.

[0014] 2. This application can facilitate the normal passage of personnel and small vehicles while blocking the breach.

[0015] Another aspect of the present invention provides a method for rapid repair of a flood dam, comprising:

[0016] Place the bellows: Place the bellows at the breach perpendicular to the dam, so that water flows along the bellows;

[0017] During the deployment of the bellows, sandbags are used to fill the gaps between the bellows and / or between the bellows and the embankment;

[0018] After the deployment of the corrugated pipes is completed, sandbags are piled on the deployed corrugated pipes to form a rapid repair structure for the flood control dam above the water surface, and the top surface of the rapid repair structure for the flood control dam is used as a passage.

[0019] As a further solution of the present invention: the bellows has a square grid inside;

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] As mentioned in the background technology of this application, it has been found through research that after the arrival of floods, it is inevitable that the dams 1 in some areas will be damaged, causing breaches and flood disasters, while the existing technology cannot quickly seal the breaches and has certain defects.

[0030] In order to solve the above-mentioned defects, the present application discloses a rapid repair structure for flood control dams, which can quickly seal breaches and reduce disaster losses.

[0031] The following will describe in detail how the solution of the present application solves the above technical problems in conjunction with the accompanying drawings.

[0032] See also Figures 1 to 4 In an embodiment of the present invention, a rapid repair structure for a flood dam includes: a plurality of steel bellows 3 placed in parallel, and a first sandbag 4 arranged outside the steel bellows 3, wherein the interior of the steel bellows 3 is filled with a second sandbag 6, and a grid 5 is fixedly connected to the outlet end of the steel bellows 3. The present application can quickly block the breach 2 by setting the steel bellows 3, the first sandbag 4, the grid 5 and the second sandbag 6 to reduce disaster losses. In a specific implementation, the number of parallel steel bellows 3 can be two or more.

[0033] In this embodiment, the top surface of the first sandbag 4 is flush with the top surface of the dam 1. This arrangement ensures that people and small vehicles can pass through the breach 2 normally.

[0034] In this embodiment, the steel bellows 3 is placed in the breach 2 of the dam 1, and the placement direction of the steel bellows 3 is perpendicular to the dam 1. This arrangement ensures that water can continue to flow through the steel bellows 3 after the steel bellows 3 are placed.

[0035] In this embodiment, the first sandbag 4 fills the gap between the steel corrugated pipe 3 and the breach opening 2. This arrangement ensures that the breach opening 2 can be successfully blocked.

[0036] The working principle of the present invention is: when in use, a steel bellows 3 is placed at the breach opening 2, and is placed perpendicular to the direction of the dam 1. A grid 5 is welded at one end of the steel bellows 3. After the steel bellows 3 are placed, water can continue to flow through the steel bellows 3. Then, a first sandbag 4 is placed between the steel bellows 3 and between the steel bellows 3 and the breach opening 2 of the dam 1. The gap is filled densely with the first sandbag 4. The first sandbag 4 is also stacked on the steel bellows 3. The height of the first sandbag 4 is higher than the water surface. After the first sandbag 4 is stacked, people and small vehicles can pass above the first sandbag 4. At the same time, a second sandbag 6 is filled into the steel bellows 3. The second sandbag 6 needs to be filled on the water inlet side. The grid 5 at the water outlet inside the steel bellows 3 can block the second sandbag 6 to prevent the second sandbag 6 from being washed away by the water flow. After the second sandbag 6 inside the steel bellows 3 is filled densely, the breach opening 2 can be blocked, and vehicles can pass normally above it. In addition, the structure can be used as a temporary plug or a permanent plug. After the flood recedes, the steel corrugated pipe 3 can be plugged with a steel plate on the water-facing surface, or reinforced concrete can be used to cast a retaining wall.

[0037] The present application discloses a method for rapid repair of flood control dams, comprising:

[0038] Place the bellows: Place the bellows at the breach perpendicular to the dam, so that water flows along the bellows;

[0039] During the deployment of the bellows, sandbags are used to fill the gaps between the bellows and / or between the bellows and the embankment;

[0040] After the deployment of the corrugated pipes is completed, sandbags are piled on the deployed corrugated pipes to form a rapid repair structure for the flood control dam above the water surface, and the top surface of the rapid repair structure for the flood control dam is used as a passage.

[0041] The rapid repair method for flood control dams of the present invention can construct the aforementioned rapid repair structure for flood control dams, thereby being able to quickly seal breaches, reduce disaster losses, and enable personnel and small vehicles to quickly resume passage.

[0042] In the specific implementation, when placing the corrugated pipe, the corrugated pipe should be placed as horizontally as possible at the breach, so that the water can flow smoothly through the corrugated pipe, reduce the impact of the water flow on the corrugated pipe, and keep the corrugated pipe stable. After each corrugated pipe is placed at the breach, sandbags are used to fill the gap between the corrugated pipe and other corrugated pipes or the dam to keep the corrugated pipe stable. When the corrugated pipe at the breach reaches a certain height, sandbags are piled on the already placed corrugated pipes, which can not only press and fix the already placed corrugated pipes, but also flatten the top into a passable road.

[0043] See also Figures 1 to 4, as an embodiment of the present invention, the bellows has a square grid inside;

[0044] After stacking sandbags on the deployed corrugated pipe, fill the water inlet end of the deployed corrugated pipe with sandbags until the corrugated pipe is blocked by the sandbags. In the process, the sandbags washed away by the water flow are intercepted by the grid.

[0045] In a specific implementation, there is a grid inside the bellows, and the grid is close to the middle part of the bellows or biased towards the water outlet of the bellows. After the bellows is put into the breach, sandbags are filled into the water inlet, so that the sandbags washed away by the water flow can be intercepted by the grid inside the bellows, thereby preventing the sandbags from being washed away by the water flow. After the sandbags fill the bellows tightly, the breach can be blocked. After stacking sandbags on the already placed bellows, sandbags are filled into the water inlet of the already placed bellows to prevent the bellows from being washed away after the resistance of the bellows increases.

[0046] See also Figures 1 to 4 As an embodiment of the present invention, after the flood recedes, a steel plate is sealed on the water-facing surface of the flood control dam rapid repair structure or a reinforced concrete retaining wall is cast to seal the water inlet end of the corrugated pipe.

[0047] In specific implementation, the flood control dam rapid repair structure of this embodiment can be used as a temporary plugging, and after the flood recedes, the flood control dam rapid repair structure of this embodiment can be removed. The flood control dam rapid repair structure of this embodiment can also be used permanently. After the flood recedes, a steel plate can be set on the water-facing surface or a retaining wall can be cast using reinforced concrete to block the corrugated pipe, further stabilize the flood control dam rapid repair structure, and make the flood control dam rapid repair structure a permanent part of the dam.

[0048] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.

[0049] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
