Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering, and in particular to a steel wire rope traction reinforcement structure for the outer side of a steel cofferdam. Background Technology

[0002] Cofferdam engineering is a crucial temporary engineering project. During the construction of water conservancy projects, it is a temporary retaining structure built to prevent water and soil from entering the proposed construction site of structures, facilitating drainage, excavation, and construction within the cofferdam. Cofferdams can be categorized into earth-rock cofferdams, concrete cofferdams, and steel cofferdams. Steel cofferdams are particularly favored due to their ease of construction, shorter construction period, and lack of pollution to river water during operation. Steel sheet pile cofferdams, steel pipe pile cofferdams, and PLC composite pile cofferdams (a combination of both) are widely used.

[0003] Due to their unique composition, steel cofferdams have some obvious limitations and shortcomings, which can be summarized as follows: 1. Steel cofferdams are susceptible to deformation due to factors such as water flow velocity and water level changes, posing a risk of deformation exceeding warning values ​​during use. 2. Deformation of steel cofferdams can easily lead to the detachment of connecting locks or loose connections, increasing the risk of leakage. 3. The safety of steel cofferdams is closely related to the riverbed geological conditions. If the riverbed consists of sandy soil layers, thick silt deposits, or sand mining pits, it cannot provide effective support for the steel cofferdam's embedment, posing a significant risk to its stability.

[0004] In summary, traditional steel cofferdams have significant shortcomings in adapting to various river conditions and riverbed geology, particularly in terms of safety and reliability. These issues have prompted the industry to seek more reliable solutions. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a steel wire rope traction and reinforcement structure on the outside of a steel cofferdam, which can effectively prevent cofferdam deformation, improve the safety of the cofferdam, and be reused, thereby overcoming the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, this utility model provides a steel wire rope traction reinforcement structure for the outer side of a steel cofferdam, including anchor piles, shaping clamps and steel wire ropes; The anchor piles are driven into the outside of the steel cofferdam and arranged in a row along the length of the steel cofferdam. Each anchor pile is wrapped with a steel wire rope, and the other end of the steel wire rope is connected to the shaping clamp. The shaped fixture includes a clamping plate and a connecting plate. The clamping plate is in the shape of an inverted U and is used to clamp and fix it to the top of the steel cofferdam. The connecting plate is fixedly connected to the outer wall of one side of the clamping plate and has a connecting hole for connecting to a steel wire rope.

[0007] As an improvement of this utility model, a limiting collar is provided around the outer periphery of the anchor pile. The limiting collar includes four identical arc segments, each arc segment having a buckle at both ends. The four arc segments together form a ring, and the buckles connected to each other are fixed by bolts. A steel wire rope is wound around the outer periphery of the limiting collar and located below the buckles.

[0008] Furthermore, eight right-angled triangular limiting steel wedges are uniformly welded around the outer periphery of the anchor pile, and the limiting collar is located below the limiting steel wedges.

[0009] Furthermore, the limiting steel wedge is located 2m below the water level elevation.

[0010] Furthermore, the wire rope includes a first wire rope and a second wire rope. The first wire rope is wound around the anchor pile and locked with three rope clamps. The second wire rope is connected to the shaping fixture and locked with three rope clamps. The first wire rope and the second wire rope are connected by a connecting device.

[0011] With this design, the present invention has at least the following advantages.

[0012] 1. This utility model can effectively prevent the deformation of the cofferdam and improve its safety.

[0013] 2. It can be reused, reducing construction costs.

[0014] 3. The structure is simple and the construction is convenient and flexible. It can be constructed simultaneously or in conjunction with the cofferdam without affecting the overall construction period. Attached Figure Description
