Technical Field

[0001] This utility model relates to the field of pressure-bearing cofferdam technology, specifically to a method for installing and dismantling pressure-bearing cofferdams. Background Technology

[0002] In many fields such as water conservancy and hydropower projects, bridge engineering, and port engineering, it is often necessary to carry out foundation construction underwater, such as bridge pier foundations, underwater tunnels, and port wharves. These constructions need to be carried out in a dry environment to ensure construction quality and safety, which requires the use of pressure cofferdams. Pressure cofferdams can intercept water flow and keep the construction site dry.

[0003] However, existing cofferdam technologies have some limitations. For example, traditional cofferdam assembly and connection methods usually use welding or bolt fixing. The entire installation and dismantling process is time-consuming and labor-intensive, requiring professional welding equipment and personnel, which increases construction costs and time. The complex connection method makes the installation and dismantling process of the cofferdam cumbersome, requiring a lot of time and manpower, which seriously affects construction efficiency. Therefore, a method for installing and dismantling pressure-bearing cofferdams is proposed. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 2 In this embodiment, a pressure-bearing cofferdam is installed and dismantled, including two connecting plates 1 and two baffles 2. Multiple insert rods 3 are fixed to the lower surface of the lower connecting plate 1 by bolts. Rubber sealing rings 4 are fixed to the opposite sides of the upper and lower connecting plates 1. Slots 5 are provided on the left and right sides of the opposite sides of the upper and lower connecting plates 1. Insert blocks 6 that are compatible with the slots 5 are fixed to the upper and lower surfaces of the left and right baffles 2. A connecting component 7 is provided on the opposite side of the upper and lower connecting plates 1.

[0024] In this embodiment, multiple inserts 6 are slidably inserted into the interior of the corresponding rubber sealing rings 4 and slots 5. The upper and lower surfaces of the left and right side baffles 2 abut against the opposite side of the upper and lower side rubber sealing rings 4. Multiple insert rods 3 are evenly distributed on the lower surface of the lower connecting plate 1. The left and right side slots 5 are symmetrically distributed on the left and right sides of the longitudinal central axis of the connecting plate 1. Two insertion holes are opened through the rubber sealing rings 4 for the corresponding inserts 6 to be inserted. Water can be intercepted by the left and right side baffles 2, and multiple insert rods 3 can be inserted into the foundation.

[0025] Please see Figures 3 to 4 In this embodiment, the connecting component 7 includes threaded holes 701 on the left and right sides of the upper and lower connecting plates 1 on opposite sides. Threaded rods 702 are threadedly connected inside the threaded holes 701 on both sides. Fixed rods 703 are rotatably connected to the opposite side of the threaded rods 702 on both sides through bearings. A rotating frame 704 is fixed to the outside of each threaded rod 702. A matching connecting frame 705 is provided on the outside of the opposite side of the left and right baffles 2.

[0026] Specifically, the rotating frame 704 includes a fixed cylinder, with handles fixed on both the left and right sides of the outer side of the fixed cylinder. The connecting frame 705 includes an I-shaped frame 7051, with rubber sealing strips 7052 symmetrically fixed inside the I-shaped frame 7051. The opposite sides of the rubber sealing strips 7052 on both the left and right sides abut against the opposite sides of the left and right side baffles 2. The lower connecting plate 1 is fixed to the bottom of the water or other supporting structure by multiple insert rods 3. Then, the opposite sides of the left and right side baffles 2 are slidably inserted into the left and right sides inside the connecting frame 705, and the left and right side baffles 2 are pressed in opposite directions to compress the rubber sealing strips 7052 on both the left and right sides of the I-shaped frame 7051, thereby achieving abutment and sealing, enhancing the sealing performance between the baffles 2, and preventing water from seeping in from the gaps between the baffles 2.

[0027] It should be noted that the upper connecting plate 1 is placed on the upper surface of the left and right side baffles 2, and the inserts 6 on the upper surface of the left and right side baffles 2 are slidably inserted into the slots 5 in the upper connecting plate 1. Then, the threaded rods 702 on the left and right sides are threaded into the corresponding threaded holes 701. The threaded rods 702 are rotated by the rotating bracket 704, so that the upper and lower connecting plates 1 move in opposite directions, thereby fixing the left and right side baffles 2. The rubber sealing rings 4 on the upper and lower sides can seal the connection between the connecting plate 1 and the baffle 2, thus enabling quick installation and easy disassembly.

[0028] The working principle of the above embodiments is as follows:

[0029] In use, the lower connecting plate 1 is fixed to the bottom of the water or other supporting structure by the multi-insertion rod 3. Then, the opposite sides of the left and right baffles 2 are slidably inserted into the left and right sides inside the connecting frame 705, and the left and right baffles 2 are pressed in opposite directions to compress the rubber sealing strips 7052 on the left and right sides of the I-beam frame 7051, achieving abutment sealing, enhancing the sealing performance between the baffles 2, and preventing water from seeping in from the gaps between the baffles 2. Then, the fixing blocks 6 on the lower surface of the two baffles 2 are slidably inserted into the two slots 5 in the lower connecting plate 1. The upper connecting plate 1 is placed on the upper surface of the left and right side baffles 2, and the inserts 6 on the upper surface of the left and right side baffles 2 are slidably inserted into the slots 5 in the upper connecting plate 1. Then, the threaded rods 702 on the left and right sides are threaded into the corresponding threaded holes 701. The threaded rods 702 are rotated by the rotating frame 704, so that the upper and lower connecting plates 1 move in opposite directions, thereby fixing the left and right side baffles 2. The rubber sealing rings 4 on the upper and lower sides can seal the connection between the connecting plate 1 and the baffle 2, thus enabling quick installation and easy disassembly.
