Dismantling Security Nets from Container Houses

The following methods and precautions can be referred to when dismantling security nets from container houses:

I. Basic Dismantling Method If the security net is made of ordinary metal material with a moderate thickness, a magnet-assisted dismantling method can be used. The specific steps are as follows:

1. Tool Preparation: Select a strong magnet (such as a neodymium magnet) and a small hammer to ensure sufficient magnetic attraction.
2. Operation Process: Press the magnet tightly against the outside of the security net, and gently tap the corresponding position of the magnet from the inside with a hammer. The vibration will cause the hooks of the security net to generate a magnetic attraction effect with the magnet. Once the hooks are attracted, pull the security net outward with force to detach it from the fixing points.
3. Abnormal Handling: If there is no magnetic attraction reaction after tapping, it may be due to insufficient magnet size or an overly thick security net. In this case, replace the magnet with a larger size or contact professionals to use tools such as hydraulic shears or angle grinders for cutting and dismantling.

II. Systematic Dismantling Plan For large-scale or complex scenarios (such as community集中整治 (community-wide rectification)), the following process can be referred to:

1. Preliminary Investigation: Register the installation location, size, material (such as stainless steel, wrought iron) and fixing method (expansion screws, welding) of the security nets, and establish a rectification ledger.
2. Publicity and Mobilization: Explain the necessity of dismantling (such as fire safety and building compliance) through community announcements, WeChat groups, and other channels to enhance cooperation.
3. Classified Dismantling:
   • Self-Dismantling: Provide tool guidance and safety training for residents who actively declare their intention to dismantle.
   • Unified Dismantling: For those who have not declared but are cooperative, the street office can entrust a construction team to use professional equipment (such as electric drills and gas cutting torches) for dismantling and clean up the site.
4. Acceptance and Control: After dismantling, check whether the wall is damaged and establish a long-term supervision mechanism for illegal reinstallation.

III. Cost Reference The dismantling cost is affected by the region, material, and mesh density:

• Ordinary wrought iron security nets: Approximately 30-80 yuan per square meter (including labor and cleaning).
• Stainless steel or thickened materials: Approximately 80-200 yuan per square meter, requiring more professional tools.
• High-altitude operations or complex structures: The cost may increase by 30%-50%, requiring the erection of scaffolding or the use of hanging baskets.

IV. Safety Tips

1. Cut off the power supply before dismantling to avoid touching the original wiring.
2. Wear safety harnesses for high-altitude operations and set up warning areas below.
3. Dispose of waste security nets as recyclables to avoid indiscriminate disposal.

If there are doubts about the structural stability or dismantling difficulty, it is advisable to contact a qualified construction team first to ensure compliance and safety in operations.
