Description

Technical Field

[0001] The utility model relates to the technical field of cofferdam reinforcement, in particular to a reinforced cofferdam structure. Background Art

[0002] A cofferdam refers to a temporary retaining structure built during the construction of a water conservancy project to create a permanent water conservancy facility. It usually creates a circular space in the water area, and then the water is pumped out to create a waterless environment, making it easier to carry out cement pouring and other work.

[0003] However, in the process of pumping water after the cofferdam is formed, as the internal water is gradually pumped out, the external water pressure will directly act on the outer wall of the cofferdam. Therefore, in addition to the connection between the cofferdam baffles, the cofferdam plates need to be reinforced. Currently, common cofferdam reinforcement structures are triangular in shape, which are adjusted to form triangular brackets that support the inner wall of the cofferdam plate and the ground. However, this method has certain disadvantages. First, the triangular bracket will extend more toward the inner wall of the cofferdam during the splicing process, so it will take up a certain amount of space. In this way, it is necessary to expand the scope of the cofferdam at the beginning of the cofferdam construction, which increases the budget and engineering volume. Secondly, the triangular bracket has a low range of action, so a large number of triangular brackets need to be prepared, which wastes a lot of manpower and material resources in installation and subsequent disassembly.

[0004] Therefore, it is necessary to provide a new reinforced cofferdam structure to solve the above technical problems. Utility Model Content

A fixing plate 16 is fixedly installed on one end of the rotating shaft 13 . An adjusting chamber 17 is movably installed on the fixing plate 16 .

[0029] An adjusting rod 18 is rotatably mounted on the inner walls of both sides of the adjusting chamber 17. One end of the adjusting rod 18 extends outside the adjusting chamber 17 and is fixedly mounted with a knob for easy operation by the staff. Two transmission blocks 19 are slidably mounted in the adjusting chamber 17. The adjusting rod 18 passes through the two transmission blocks 19 and is threadedly connected thereto. Figure 4As shown, two sliding rods are fixedly installed on the inner walls on both sides of the adjusting bin 17, and the two sliding rods pass through the two transmission blocks 19 and are slidably connected thereto. A fixed plate 16 is fixedly installed on one end of the rotating shaft 13, and two hinged plates 20 are arranged between the fixed plate 16 and the adjusting bin 17. One side of the two transmission blocks 19 extends to the outside of the adjusting bin 17, one end of the two hinged plates 20 is rotatably connected to the fixed plate 16, and the other ends of the two hinged plates 20 are rotatably connected to the two transmission blocks 19 respectively.

[0030] The working principle of the reinforced cofferdam structure provided by the utility model is as follows:

[0031] When the cofferdam needs to be reinforced, the staff can first use the two base plates 1 to fix the mounting plate 5 at a suitable position in the cofferdam, and fix the base plate 1 to the ground through the ground anchor 4. A certain distance is maintained between two adjacent mounting plates 5, and the two adjacent mounting plates 5 are connected to the threaded rod 8 through the receiving tube 7.

[0032] Furthermore, the staff can rotate the adjusting rod 18, and the rotation of the adjusting rod 18 will drive the two transmission blocks 19 to move toward each other. Under the effect of the two hinged plates 20, the adjusting bin 17 will move horizontally and eventually hit the inner wall of the cofferdam. At the same time, the staff can pull out the pin rod 15 upwards, and the pin rod 15 will contact the limiting effect of the rotating shaft 13 when pulled out. The staff can then adjust the adjusting bin 17 to a horizontal or vertical state, thereby increasing the scope of application of the device.

[0033] After the multiple mounting plates 5 are fixed, the connecting plates 11 on the accommodating tube 7 and the threaded rod 8 can be respectively inserted into the two side blocks 6 close to each other between the two adjacent mounting plates 5. The connecting plates 11 are inserted into the tooth grooves 601 to increase the coordination between the two adjacent mounting plates 5. During this process, the staff can rotate the rotating sleeve 9. The rotating sleeve 9 will cause the threaded rod 8 to move out of the accommodating tube 7, thereby extending the length of the accommodating tube 7 and the threaded rod 8.

[0034] At the corner of the cofferdam, two adjacent mounting plates 5 can be connected by a connecting block 10, and the connecting plates 11 at both ends of the connecting block 10 are respectively inserted into the side blocks 6 on the two adjacent mounting plates 5, so as to increase the coordination between the two mounting plates 5 at the corner. In this way, after the mounting plates 5 are spliced ​​around the inner wall of the cofferdam, all the mounting plates 5 are connected to each other, thereby enhancing the resistance to pressure. The longitudinal and lateral water pressures are resisted by multiple support plates 3 and vertical columns 2, which improves the reinforcement effect of the cofferdam to a certain extent.

[0035] Compared with the related art, the reinforced cofferdam structure provided by the utility model has the following advantages:

[0036] Beneficial effects:

[0037] The utility model provides a reinforced cofferdam structure. When the inner wall of the cofferdam is reinforced, two adjacent mounting plates 5 can be connected together through the accommodating tube 7 and the threaded rod 8, and the two mounting plates 5 at the corners can be connected together with the help of the connecting block 10. In this way, a plurality of mounting plates 5 surrounding the inner wall of the cofferdam can be connected together, thereby increasing the coordination between the plurality of mounting plates 5, and resisting water pressure from each other, thereby increasing the firmness of the cofferdam to a certain extent. At the same time, the support plates 3 on both sides and the vertical columns 2 form a triangular structure, which does not take up too much space.
