Double-wing prefabricated houses are a flexible and convenient form of temporary construction, widely used in construction sites, exhibitions, temporary offices, and other locations. To ensure the stability and safety of double-wing prefabricated houses, foundation treatment is particularly important. The following is a detailed discussion of foundation treatment for double-wing prefabricated houses.

I. Necessity of Foundation Treatment

Stability: Double-wing prefabricated houses are typically built on varying terrains. Foundation treatment effectively improves their stability and prevents tilting and settlement.

Safety: Improper foundation treatment may lead to safety hazards during use, affecting the safety of personnel.

Lifespan: Proper foundation treatment can extend the lifespan of prefabricated houses and reduce later maintenance costs.

II. Common Foundation Treatment Methods

**Ground Leveling:** Before constructing the prefabricated house, the ground must be leveled to ensure there are no significant unevenness.

**Pile Foundation:** On soft or unstable soil, pile foundations can be used to enhance the bearing capacity of the foundation.

**Concrete Foundation:** For applications requiring long-term use, a concrete foundation can be considered to provide stronger support.

**Subbase Treatment:** Laying a subbase (such as gravel or sand) on the foundation can effectively distribute the weight of the prefabricated house and reduce foundation settlement.

**Drainage System:** A drainage system must be designed during foundation treatment to prevent rainwater accumulation and damage to the foundation.

III. Construction Precautions

**Geological Survey:** Before foundation treatment, a geological survey of the construction site is necessary to understand the soil properties and bearing capacity.

**Material Selection:** Suitable materials should be selected for foundation treatment to ensure good bearing capacity and durability.

Construction Process: Strictly adhere to the construction process to ensure each step meets standards and avoids foundation problems caused by improper construction.

Regular Inspection: During the use of the prefabricated house, regularly inspect the foundation to promptly identify and address potential issues.

Through the above discussion on foundation treatment for double-wing prefabricated houses, it can be seen that proper foundation treatment not only improves the stability and safety of the prefabricated house but also extends its service life. In actual construction, appropriate treatment methods should be selected based on specific circumstances, and construction specifications should be strictly followed to ensure the safe use of the prefabricated house.
