Technical Field

[0001] This utility model relates to the field of civil engineering, and in particular to a steel caisson cofferdam lowering and hanging device, which is suitable for the construction of steel caisson cofferdam lowering. Background Technology

[0002] Steel caisson cofferdams are a key technological equipment widely used in underwater construction, especially in bridge and hydraulic engineering projects. They are typically used for water containment operations to create a dry construction environment, ensuring the smooth progress of complex foundation construction. In underwater operations, due to the complex and variable aquatic environment, the stability and construction efficiency of the cofferdam become crucial to the success or failure of the project. Therefore, the design of a rationally designed steel caisson cofferdam and its related hoisting devices is particularly important.

[0003] During the lowering of the steel caisson cofferdam, the suspension system plays a crucial role in load-bearing, adjustment, and balancing. The suspension system not only needs to withstand the weight of the cofferdam but also adapt to the specific conditions of the construction site, including water flow, depth, and terrain. Furthermore, to ensure the safety and accuracy of the construction, the suspension system must possess high reliability and ease of operation, which places higher demands on the design and performance of the suspension equipment.

[0004] Traditional hoisting devices often suffer from problems such as complex operation, low adjustment efficiency, and insufficient adaptability, especially in construction environments with strong water flow or complex terrain, where they often fail to meet actual needs. Furthermore, during the lowering of the cofferdam, instability and uneven stress on the hoisting points may occur, increasing construction difficulty and safety risks.

[0005] Therefore, developing more intelligent and efficient steel cofferdam hoisting devices has become an important direction for technological development in the industry. Summary of the Invention
