Description

Technical Field

[0001] This invention belongs to the field of dam breach sealing technology, specifically relating to a method and apparatus for sealing dam breaches. Background Technology

[0002] During the flood season, if a breach occurs in a dike, it needs to be sealed immediately to avoid endangering nearby residents. Conventional breach sealing methods typically involve using objects to block the breach, such as the "A Throw-in Dike Breach Sealing Device and Method" disclosed in the existing patent with publication number CN113585173A, which includes an upper mesh and a lower support mesh, with a steel ring fixedly connected to the bottom of the upper mesh... This type of sealing device uses a mesh structure to collect stones, sandbags, and other materials together, and then throws them at the breach in the dike to achieve the sealing effect.

[0003] In the existing technology, the dike breach sealing device requires connecting two steel hoops together. The existing connection method mostly uses multiple bolts and nuts, which reduces the assembly efficiency of the device at the breach site and makes it impossible to complete the assembly quickly at the breach site. This reduces the sealing efficiency of the breach to a certain extent. Therefore, the present invention proposes a dike breach sealing method and device. Summary of the Invention

[0004] The purpose of this invention is to provide a method and apparatus for sealing and dealing with dam breaches, so as to solve the problem of low assembly efficiency of existing dam breach sealing and dealing devices mentioned in the background art.

The upper cover consists of an upper steel hoop, a connecting hoop, end blocks, and a nylon woven mesh. The lower cover consists of a lower steel hoop, a connecting hoop, end blocks, and a nylon woven mesh. Both covers can be filled with sealing counterweights and assembled together. The connecting hoop is welded to the upper steel hoop and to the lower steel hoop. The connecting hoop is welded to the end blocks. The nylon woven mesh is installed between the connecting hoop and the end blocks. An assembly structure is provided between the upper and lower steel hoops to achieve rapid assembly between the two hoops. The assembly structure includes insert blocks, side blocks, and... The system comprises a movable sleeve, a stop block, and a side rod. Multiple insert blocks are evenly fixed to the surface of the upper steel hoop, and multiple side blocks are fixed to the surface of the lower steel hoop. The bottom end of each insert block is located on one side of a side block, and a side rod is fixed to one side of each side block. A through hole is provided at the bottom end of each insert block for the side rod to pass through. The end of the side rod passes through the through hole to one side of the insert block, allowing the two steel hoops to be connected together.

The stop blocks 9 are located on one side of the side rod 10. A movable structure and a safety structure are provided between the movable sleeve 8 and the lower steel hoop 2.

[0015] In this embodiment, preferably, the movable structure includes an inner sliding groove 11, an inner slider 12, a spring 13, and a connecting block 14. Two inner sliding grooves 11 are symmetrically opened inside the lower steel hoop 2, and the inner slider 12 is movably connected to the inner sliding groove 11 through the spring 13. A connecting slide is opened on one side of the inner wall of the inner sliding groove 11, which communicates with the surface of the lower steel hoop 2. A connecting block 14 is fixed on one side of the inner slider 12. One end of the connecting block 14 extends through the connecting slide to the surface of the lower steel hoop 2 and is fixed to the movable sleeve 8. The movable sleeve 8 can slide up and down with the connecting block 14, so that the movable sleeve 8 can be pushed back and reset by the spring 13 after sliding down. A bottom groove is opened on the bottom surface of the inner slider 12, and the top end of the spring 13 is inserted into the bottom groove to ensure the stable installation of the spring 13.

[0017] A method for sealing a breach in a dike includes the following steps: Step 1: First, fill the upper and lower covers with stones, sandbags, and other sealing and counterweight materials; Step 2: Then, quickly assemble the upper steel hoop 1 and lower steel hoop 2 on the upper and lower covers using the assembly structure to achieve rapid assembly of the dam breach sealing device. During assembly, first, forcefully rotate the guide column 16 90 degrees to align the limiting block 17 with the side groove 19. Then, place the upper steel hoop 1 on top of the lower steel hoop 2, and position the insert block 6 above the stop block 9. At this time, move the upper steel hoop 1 down, causing the insert block 6 to press down the stop block 9 and the movable sleeve 8, and causing the connecting block 14 to move down with the inner slider 12, so that the spring 13 is gradually compressed until the insert block 6 moves down to one side of the side rod 10. At this time, rotate the upper steel hoop 1 to make the insert block 13 move down. The bottom end of block 6 can be fitted onto side rod 10 until the insert block 6 and side block 7 are in contact. At this time, the insert block 6 no longer presses down on the stop block 9, so that the inner slider 12 is reset under the push of spring 13, and the connecting block 14 moves up and resets with the movable sleeve 8 and the stop block 9. Finally, the stop block 9 moves up to one side of the side rod 10, which can effectively block and limit the insert block 6, ensuring the assembly stability between the upper steel hoop 1 and the lower steel hoop 2. Finally, the guide post 16 is rotated 90 degrees so that the limiting block 17 is no longer aligned with the side groove 19. The limiting block 17 can prevent the movable sleeve 8 from sliding down accidentally, ensuring the overall stability of the device. Step 3: After assembly, use a crane or other hoisting equipment to lift the entire device and transport it to the area above the breach in the dam. Step 4: Slowly lower the entire device into the breach in the dam. The device, which contains stones, sandbags, and other sealing counterweights, will then block the breach, enabling rapid treatment of the breach.
