Description

Technical Field

[0002] A cofferdam refers to a temporary retaining structure built in the construction of permanent water conservancy facilities during water conservancy project construction. Its function is to prevent water and soil from entering the construction site of the building so as to drain water, excavate foundation pits, and build buildings within the cofferdam. It is generally used in hydraulic structures. Different types of cofferdams are derived according to different usage environments. Among them, steel sheet pile cofferdam is a common one. The steel sheet piles are located on the periphery to block the water flow, and related structures such as support frames are located inside the steel sheet piles to support and reinforce the steel sheet piles. During the construction of the cofferdam, in order to ensure that the subsequent use of the cofferdam is not affected by water pressure and remains stable in the water, it is necessary to set support frames and other reinforcement structures on the cofferdam to increase the stability of the cofferdam. The construction height of the cofferdam corresponds to the water depth. When the water is shallow, the distance between the two support frames is relatively close, otherwise the distance is relatively far.

[0003] However, when faced with waters of different depths, the position of the support frame can only be temporarily adjusted by disassembly and assembly, and cannot be quickly adjusted to accommodate steel sheet piles of different heights, which causes certain inconveniences during use.

[0039] The implementation principle of a cofferdam reinforcement structure in the embodiment of the present application is:

[0040] During the use of the cofferdam, when the height of the cofferdam needs to be increased, the height of the steel cofferdam 11 needs to be adaptively adjusted. During operation, the motor 7 is started, and the output shaft of the motor 7 will drive the threaded rod 6 fixedly connected thereto to rotate. When the threaded rod 6 rotates, it is restricted by the two circular rods 15, and the moving block 9 will gradually move upward on the threaded rod 6 and the two circular rods 15. The moving block 9 drives the steel cofferdam 11 to move upward synchronously through the four connecting rods 10. While the steel cofferdam 11 moves upward, it drives the four docking rods to slide in the four rectangular grooves. After the steel cofferdam 11 is adjusted to a suitable height, the motor 7 can be turned off, and then the steel cofferdam 11 will keep its height unchanged.

[0041] The two rotating rods 18 are then rotated in sequence, and the rotating rods 18 drive the annular block fixed thereto to move synchronously, and the rotating rods 18 gradually move toward the outside of the set block 17. During the movement of the rotating rods 18, they will gradually slide out of the corresponding limiting holes 16 until the annular block contacts the inner wall of the annular groove on the side away from the circular rod 15. The movement of the rotating rods 18 is restricted and will stop moving. At this time, the rotating rods 18 have been adjusted to a predetermined position. After the two rotating rods 18 have slid out of the two limiting holes 16, the set block 17 can be pushed upward so that the set block 17 is located in the middle position of the steel enclosure 11 and the steel enclosure 2 14. Then, the two rotating rods 18 are rotated in opposite directions in sequence, and the ends of the two rotating rods 18 that are close to each other are re-inserted into the corresponding two rotating rods 18. The set block 17 is fixed by the two rotating rods 18, and the steel enclosure 3 20 is used to increase the supporting effect on the steel sheet pile 1, thereby reducing the pressure exerted by the water pressure on the steel sheet pile 1.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
