Technical Field

[0001] The utility model relates to the technical field of underwater engineering construction, in particular to an underwater hole plugging and sealing device. Background Technique

[0002] The sinking and installation of the bucket foundation structure is a commonly used technology in underwater construction, mainly used for infrastructure construction in deep water areas, such as the support structure of bridges, the foundation of offshore wind power, port facilities, etc. According to factors such as geological conditions, water depth, and water flow, the size, shape, and material of the bucket foundation structure are designed for structural stability, bearing capacity, and durability analysis, and then the bucket foundation structure is sunk to the seabed by filling water layer by layer or other methods. Control the sinking speed to ensure the structure lands smoothly.

[0003] In underwater engineering construction, an underwater hole plugging and sealing device is required. During the sinking and installation of the traditional bucket foundation structure in the prior art, when there are interlayers or sandy soil layers in the foundation, the sinking force formed by the air extraction and drainage of the traditional bucket foundation structure may not be able to penetrate this kind of geology, resulting in installation failure. In subsequent construction, medium and coarse sand needs to be backfilled in the bucket. To prevent seawater from entering the bucket through the holes on the side wall of the upper bucket, hole plugging measures need to be taken. Before hole plugging, divers are required to cut all the affected water pipes and air pipes, which increases the cost and work complexity and cannot meet the use requirements. Therefore, an underwater hole plugging and sealing device is proposed to solve the problems mentioned above. Content of the Utility Model

[0027] Specifically, the outer diameter of the C40 concrete plugging column 32 is adapted to the inner diameter of the installation cavity 2. A rubber water stop 33 that abuts against the connection part of the installation cavity 2 is sleeved outside the C40 concrete plugging column 32. The rubber water stop 33 is annularly distributed outside the C40 concrete plugging column 32. By setting the rubber water stop 33, a sealing surface is formed between the C40 concrete plugging block 31, the C40 concrete plugging column 32 and the installation cavity 2 to prevent water and impurities from entering.

[0028] It should be noted that the thickness of the steel plate 35 is two centimeters, and the outer diameter of the steel plate 35 is adapted to the aperture of the installation cavity 2. The screw rod 34 is L - shaped, and a tie - rod nut 36 is threadedly connected to one end of the screw rod 34 away from the C40 concrete plugging column 32. By setting the steel plate 35 to apply pressure to the outside of the bucket - type foundation structure body 1, it is ensured that the sealing structure is closely fitted with the installation cavity 2.

[0029] In addition, the tie - rod nut 36 is located on the side of the steel plate 35 away from the C40 concrete plugging column 32, and a socket hole adapted to the screw rod 34 is opened inside the steel plate 35.
