Description

Technical Field

[0001] This utility model belongs to the field of mechanical adjustment device design technology, specifically relating to a wall-connected adjustment device for scaffolding construction in nuclear power plants. Background Technology

[0002] The primary purpose of the seawater filtration system in a nuclear power plant is to filter seawater and prevent marine organisms and other impurities from entering the cooling system. During each major overhaul of the nuclear power unit, the filtration mesh requires cleaning, polishing, and other inspections and maintenance. Initially, to facilitate filtration maintenance, cantilevered scaffolding was erected above the filtration mesh, allowing for inspection and maintenance of each mesh section by rotating the mesh. Therefore, during periods when the filtration mesh is not in operation, holes need to be drilled in the concrete wall above the mesh to install wall ties to support the scaffolding. Due to the highly corrosive nature of seawater, these wall ties will weaken due to corrosion during the next overhaul cycle, failing to meet safety requirements and posing a safety hazard of breakage and foreign object leakage. Therefore, after the filtration mesh inspection and maintenance are completed, the civil engineering team must remove the wall ties. With each overhaul, the wall requires repeated drilling and repairs, significantly damaging the overall strength of the wall and affecting the safe operation of the nuclear power plant. Furthermore, each installation of wall ties requires a 48-hour drying period for the concrete before use, significantly extending the maintenance time for the marine engineering system.

[0003] Similar issues arise during the maintenance of external walls in the production phase of nuclear power plants. The erection of scaffolding at heights requires the installation of wall ties according to regulations. However, since the building is already in use, it's impossible to drill holes in the walls again to install these ties, and suitable installation locations are lacking. Forcing the installation of wall ties could damage the structural walls and potentially lead to safety risks during scaffolding erection. The installation and removal of wall ties, as well as the difficulties in scaffolding erection, during the maintenance of the existing nuclear power plant's ventilation system and external walls present multiple challenges, including extended construction periods, increased maintenance costs, and potential safety hazards. These problems not only affect the maintenance efficiency of nuclear power plants but may also threaten the safe operation of equipment. Utility Model Content
