Gansu Foam Mobile Toilet Construction

The construction of foam mobile toilets in Gansu mainly utilizes movable frame structures and the characteristics of foam materials to quickly build and install toilet facilities through standardized steps. The specific construction process and key points are as follows:

I. Construction Steps

1. Preparation
   Determine the construction site and complete the measurement and layout, clarifying the toilet's floor area, orientation, and drainage direction. At the same time, prepare foam materials (such as polystyrene foam boards), frame structures (steel or aluminum alloy), construction tools (electric drills, cutting machines, spirit levels, etc.), and check whether the material quality meets standards for thermal insulation, corrosion resistance, and sound insulation.

2. Frame Structure Construction
   Assemble the toilet frame at the construction site according to the floor plan drawings. If bolted connections are used, ensure that the bolts are tightened without looseness; if it is a welded structure, check the flatness of the welds to avoid cold welds. The verticality and levelness of the frame need to be calibrated with a spirit level, with a deviation not exceeding ±3mm to ensure overall stability.

3. Foam Material Filling
   Measure and cut the foam boards according to the frame dimensions, with an error controlled within ±2mm. Embed the cut foam boards into the frame and fix them using special glue or clips to ensure there are no gaps between the boards and the frame or between the boards themselves. The roof foam boards need to have a drainage slope reserved (usually 2%-5%) to prevent water accumulation and leakage.

4. Installation of Toilet Facilities
   Position facilities such as toilets and sinks according to the design drawings and fix them to the foam boards using expansion bolts. If installing lighting equipment or sockets, pre-embed wire conduits and ensure proper insulation to avoid short-circuit risks. After all facilities are installed, test their functions, such as toilet flushing and faucet water flow.

5. Detail Refinement
   Check whether the joints of the foam boards and the fixing points of the facilities are secure, and correct any loose or misaligned parts. Apply waterproof coating (such as polyurethane waterproof coating) to the walls, roof, and other areas, with a coating thickness of not less than 1.5mm, ensuring there are no missed areas or bubbles.

II. Construction Precautions

• Safety Protection: Construction personnel need to wear gloves, safety helmets, goggles, and other equipment to avoid inhaling dust generated when cutting foam boards or being scratched by the frame.
• On-site Management: Stack materials by category, keep flammable foam boards away from fire sources, and clean up construction waste in a timely manner to keep passageways clear.
• Quality Monitoring: Regularly check the welding points of the frame, the density of the foam boards (usually ≥18kg/m³), and the integrity of the waterproof layer to ensure compliance with the requirements of the "Technical Specifications for Mobile Toilets".
• Compliance Communication: Before construction, it is necessary to report to the local urban management and environmental protection departments and comply with regulations on noise and dust control to avoid affecting the surrounding environment.
