Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy protection, in particular to a fast caisson for dam breaches. Background Art

[0002] During the flood season with heavy rain, river dams and other dams often break. The rapid sealing of the breach is related to the safety of life and property of the general public and is of great significance. At present, the main methods for sealing the breach of dams are earth and stone material placement, shipwreck blocking, steel-wood-earth-rock composite dam, etc. Because the single blocking sandbag and stone cage unit is small in size and light in weight, the above methods are inefficient and slow in sealing the breach, and the comprehensive cost is also very high. The commonly used methods of placing stone cages and stone piers are difficult to grasp the placement position, causing problems such as river blockage. Traditional caissons are mostly cubic in structure, which have greater resistance when transported by helicopter, and the structural strength is not enough. They are also easily damaged by huge water flow in the water.

[0003] Application No.: CN202022074058.4 discloses a blocking caisson and a honeycomb caisson combination including the blocking caisson, which includes a box body, the box body includes a box body frame, a top plate and side plates fixed on the box body frame, the bottom of the box body is provided with a movable valve plate, a supporting frame is installed in the box body, and a plurality of air outlets are opened on the top plate of the box body. The new type of caisson adopts a six-sided column structure, which not only has good load-bearing capacity but also saves manufacturing materials; the overall appearance of the six-sided column structure tends to be round, and the wind resistance is reduced during helicopter lifting, and the lifting process is more stable; after multiple six-sided column caissons are dropped into the water, a honeycomb structure is formed, and the boxes are easy to align with each other. The overall structural stability is strong and the contact area between the caissons is larger, which can effectively block various dam breaches or pipe bursts.

[0004] However, when the above device is used, the installation of each part of the device is not taken into consideration, making the above device inconvenient during transportation. Therefore, it is necessary to propose a rapid caisson for dam breach. Utility Model Content
