Technical Field

[0001] This utility model relates to the technical field of highway bridge engineering, and in particular to a safety ladder cage construction structure for underwater piers and water-based operations. Background Technology

[0002] To address the construction of underwater piers, most existing technologies involve conducting operations during the dry season (March to June), or utilizing underwater cofferdams to create landing conditions for ladders and constructing platforms on the water surface, relying on climbing equipment and passageways for workers to ascend and descend. Simultaneously, to ensure the safe access of workers to the underwater pier locations, suitable boats, rafts, or waterways need to be prepared. Among these methods, underwater cofferdams are the most common and widely used.

[0003] Cofferdam construction is a common construction method used in water conservancy projects, port projects, and bridge projects. Its purpose is to ensure the closure of a body of water during construction to facilitate various construction activities. Cofferdam construction is generally divided into earth cofferdams, concrete cofferdams, and hybrid cofferdams, and the appropriate cofferdam type can be selected according to different project requirements and geographical conditions.

[0004] However, existing cofferdam construction methods have certain drawbacks, such as long construction periods and limited conditions, high construction difficulty, inconvenient assembly and disassembly, and high costs. Utility Model Content
