Disassembly of Activity House Containers

The disassembly of activity house containers should adhere to the principles of safety, orderliness, and recyclability. The specific process and key points are as follows:

I. Pre-disassembly Preparations

1. Qualification and Personnel Requirements
   • Specialized operators (such as crane operators, electricians, and welding and cutting personnel) must hold valid qualification certificates within their validity periods. All operators must be between 18 and 55 years old, free from diseases that hinder high-altitude work, and have passed occupational health examinations. Before starting work, they should receive specialized safety training to familiarize themselves with the process, hazards, and emergency response methods.
2. Technical Preparations
   • Collect the original container design drawings and node connection diagrams to clarify the structural connection methods (such as bolt positions and welding nodes). Cut off the external main power supply, remove electrical wiring and water supply and drainage pipelines, lock the main distribution box, and hang a 'Do Not Close' sign.
3. On-site Preparations
   • Set up a closed warning fence with a height of no less than 1.2 meters. The radius of the warning area should be no less than 15 meters, with dedicated personnel guarding the entrance and exit. Clear obstacles and flammable and explosive materials from the site. For night operations, set up red warning lights. Inspect the container structure to assess whether there is any deformation, corrosion, or damage, and formulate a specialized handling plan (if there is severe damage).

II. Standard Disassembly Process

1. Disassembly Sequence
   • Follow the reverse order principle of 'from top to bottom, from outside to inside'. The specific steps are: wall panels → roof panels → purlins → high-strength bolts → embedded bolts → embedded steel plates. Modular or foldable container houses can be disassembled into standardized components, improving disassembly efficiency.
2. Tools and Equipment
   • General tools include wrenches, screwdrivers, Allen wrenches, pliers, rubber hammers, electric screwdrivers/drills (low-speed gear), tape measures, and spirit levels. Specialized equipment should be selected according to the container specifications, such as gantry cranes, container forklifts, reach stackers, and straddle carriers.

III. Safety Points

1. Environmental Control
   • Do not operate in severe weather conditions such as strong winds, heavy rain, or heavy snow. Ensure that the overhead and surrounding overhead power lines in the work area meet the minimum safe distance requirements.
2. Operational Specifications
   • For high-altitude work, wear a qualified double-hook safety harness with a hanging point bearing capacity of no less than 22 kN. Do not hang it on unstable structures. For welding and cutting operations, wear protective face shields, flame-retardant gloves, and non-slip insulated work shoes. Teamwork is crucial. Do not allow a single person to operate heavy lifting or high-altitude work at risk.
3. Misconception Avoidance
   • Container houses are light-steel structures, which differ significantly from brick-and-concrete structure house demolition. Do not use traditional demolition thinking for handling. The disassembled container bodies and materials have high recycling value and should be classified and stored to achieve green and low-carbon construction.
