Container House Demolition Plan

The demolition of container houses requires adherence to systematic procedures and safety regulations, with core steps including on-site assessment, structural dismantling, component classification and handling, and compliant transportation, while also strengthening safety control and resource utilization.

1. Pre-Demolition Assessment and Planning

1. Structural Safety Review
   It is necessary to verify the original construction drawings to confirm the material of the container house (such as modified shipping containers or factory-prefabricated steel structures), connection methods (welding or bolt fastening), and load distribution, assessing structural stability during the demolition process. For example, Qingdao Xinwanda Container Technology Co., Ltd. emphasizes "assessment before dismantling," determining the load-bearing capacity of the roof enclosure and frame through load testing to prevent collapse during demolition.

2. On-Site Environmental Survey
   Designate a work exclusion zone and equip it with fall protection nets and rigid barriers to prevent injuries from falling objects. For sensitive areas nearby (such as roads and pipelines), noise and dust reduction measures should be implemented, such as using water trucks or dust covers.

2. Structural Dismantling Process

1. Roof Enclosure Removal
   Use manual tools (such as wrenches and crowbars) in conjunction with light lifting equipment to sequentially remove roof skylights, insulation, and color-coated steel sheets. Throwing objects from heights is strictly prohibited. For example, Shandong's movable prefab house demolition regulations require roofing materials to be dismantled piece by piece and securely bundled to prevent scattering.

2. Frame Structure Dismantling
   Cut connection nodes in reverse order ("columns-beams-supports-floor slabs") to release residual stress. For welded structures, gas cutting equipment should be used, but flammable materials must be cleared in advance and fire extinguishers provided; for bolt-connected structures, bolts should be loosened in sequence, retaining reusable components. Direct violent toppling is prohibited to prevent damage to components or secondary disasters.

3. Component Classification and Resource Utilization

1. Material Sorting
   Classify and package steel, aluminum alloy profiles, and door and window hardware, connecting with recycling warehouses or local disposal sites. For example, in Qingdao Xinwanda's process, steel can be remelted, and insulation can be used for roadbed filling, achieving a material recycling rate of over 90%.

2. Compliant Transportation
   Obtain a construction waste clearance permit and use enclosed transport vehicles to prevent spillage. For waste containing rock wool sandwich panels, they must be packaged according to hazardous waste treatment standards to avoid fiber dust pollution.

4. Safety and Environmental Control

1. Fire Prevention and Fall Protection Measures
   The demolition site should be equipped with fire extinguishers and emergency escape routes, with flammable materials cleared before hot work. For work at heights, workers must wear safety harnesses and fall protection nets should be installed. For example, the Jinan demolition project requires daily safety briefings and records.

2. Dust and Noise Control
   Adopt wet methods (such as spray dust suppression) or enclosed dismantling workshops to control dust concentration below 10mg/m³. During noise-sensitive periods (such as at night), high-noise equipment (such as gas cutters) should be stopped.
