Container House Ground Fixation

The method for fixing a container house to the ground should be selected based on the type of house and the foundation conditions. Common methods include direct placement, welding of embedded parts for fixation, and reinforcement of support structures, while also paying attention to flatness, drainage, and load-bearing requirements.

1. Fixation Methods for Different Types of Container Houses

1. Folding/Fixed Residential Container Houses
   These have relatively low foundation requirements and can be directly placed on a leveled ground surface. If conditions permit, a cement floor can be poured and drainage ditches can be set up to enhance living comfort. For example, this method is commonly used for temporary dormitories on construction sites, allowing for quick deployment by simply leveling the ground.

2. Packing Container Houses
   These have flexible foundation requirements and can use strip foundations, pier foundations, or be directly placed on the ground. Their design allows for adjustment of support structures to adapt to different terrains, such as achieving stability through local reinforcement on slopes.

3. Container Houses Requiring High-Strength Fixation
   For long-term residential use or scenarios with high wind resistance requirements, welding of embedded parts for fixation is necessary. For example, Yashun Light Steel's patented technology involves embedding metal parts in a concrete raft foundation and welding the support column bases to the embedded parts, significantly enhancing the connection strength between the container body and the ground, enabling resistance to strong winds and earthquakes.

2. Key Construction Points

1. Ground Flatness Control
   According to the "Residential Decoration and Renovation Engineering Construction Specifications", the flatness of the base layer before laying modular floors should be ≤3mm/2m. If the ground exceeds this tolerance, self-leveling treatment should be carried out first; otherwise, it may cause floor noise or arching. For example, in the renovation of old houses in Chengdu, the first thing the experienced workers do upon entering the site is to use a 2-meter level to check the flatness.

2. Drainage and Moisture-Proof Design
   Container houses need to be set up with a drainage slope to avoid water accumulation. For example, in Shanghai, when installing, the ground level is required to be higher than the surrounding area, and drainage ditches are excavated around the container body, with a "human"-shaped canopy added on top to guide rainwater.

3. Load-Bearing and Seismic Reinforcement
   For heavy-load or seismic resistance requirements, auxiliary structures such as triangular brackets and cross brackets can be used. For example, a patented technology forms a stable base frame through the combination of triangular brackets and threaded support rods, with a second support rod set at the lower end of the cross bracket to share the load and enhance overall stability.

3. Precautions for Special Scenarios

1. Installation on Rooftops or Farmland
   It is necessary to avoid hardening the ground or building permanent foundations, as this may be considered unauthorized construction. For example, a farmland guardhouse used only for temporary tool storage and not damaging the plow layer is usually not considered unauthorized construction, but it is necessary to consult the local planning department in advance.

2. High-Humidity Environments
   In the rainy season or coastal areas, enhanced moisture-proof treatment is required. For example, in the renovation of old houses in Chengdu, prefabricated partition walls and modular floors adopt dry construction methods, eliminating the need for cement curing, which can shorten the construction period and reduce the impact of humidity.
