Description

Technical Field

[0001] This utility model belongs to the field of river construction technology, and in particular relates to a cofferdam structure for river construction. Background Technology

[0002] River construction cofferdams are temporary water-retaining structures used to protect the construction site of hydraulic structures from the impact of river flow or floods. The main types include: earth-rock cofferdams, grass-soil cofferdams, concrete cofferdams, and steel sheet pile cofferdams. Among them, steel sheet pile cofferdams are composed of single rows, double rows, or lattice-shaped steel sheet piles. They have strong erosion resistance, are safe and reliable, can be constructed and dismantled mechanically, and have a high recovery rate.

[0003] During river construction, cofferdams are often erected as temporary barriers. When using sheet pile cofferdams, holes are drilled in their surface, and reinforcing beams are fixed in place with bolts and water-stop structures to ensure the cofferdam's stability. However, after the cofferdam is dismantled, the holes need to be repaired. Therefore, a new type of cofferdam structure for river construction is needed. This new structure can use clamping structures to fix the reinforcing beams of the cofferdam, avoiding the need for repairs after use and ensuring the cofferdam's airtightness. Utility Model Content

[0004] The purpose of this utility model is to provide a cofferdam structure for river construction, which can fix the reinforcing beams of the cofferdam structure through a clamping structure, avoiding the need for repairs after the cofferdam structure is used, and ensuring the sealing performance of the cofferdam structure, thereby solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A cofferdam structure for river construction includes multiple longitudinal baffles. A retaining strip is fixedly connected to the surface of each baffle. A connecting angle plate is provided between two baffles, and the connecting angle plate is adapted to the baffle. Eight symmetrical fixing frames are provided between the multiple baffles. Two pairs of symmetrical clamps are provided on the surface of each retaining strip. Two symmetrical connecting plates are fixedly connected to the surface of each clamp. A limiting plate is fixedly connected to one side of each of the two connecting plates. A gasket is fixedly connected to one side of each of the two limiting plates. The fixing frame is located between two gaskets. Two transverse fixing bolts are provided through the surface of each of the two clamps. The fixing bolts pass through the two clamps and are threaded with nuts. Fixing bolts are provided through the top of each of the two limiting plates. The fixing bolts pass through the limiting plate, gasket, and fixing frame and are threaded with nuts. A connecting piece is provided at one end of each of the two fixing frames, and the connecting piece is adapted to the fixing frame. Four fixing bolts pass through the connecting piece and the fixing frame and are threaded with nuts.

[0006] Preferably, the inner cavity of the fixing frame is connected to two symmetrical connecting rods by fixing bolts, and the end of the connecting rod away from the fixing frame is rotatably connected to a threaded sleeve.

[0007] Preferably, the inner cavity of the fixing frame is connected to two symmetrical threaded rods by fixing bolts, and the threaded rods are threadedly connected to the threaded sleeves.

[0008] Preferably, the card strip is arranged longitudinally, the cross-section of the card strip is T-shaped, and the cross-section of the connecting corner plate is L-shaped.

[0009] Preferably, the fixing frame is a channel steel, the fixing bolt is a hexagonal bolt, the connecting piece is L-shaped, and the connecting rod and threaded rod are both inclined.
