Construction of Outdoor Mobile Toilets in Yunnan
The construction of outdoor mobile toilets in Yunnan requires selecting a plan based on the manufacturer's product characteristics and usage scenarios. The core steps include site confirmation, foundation treatment, module installation, and equipment debugging. Specific key points are as follows:
1. Site Condition Confirmation
Before construction, it is essential to verify site dimensions, power supply, and sewage conditions. For example, products from Kunming Glory Traffic Engineering Co., Ltd. require a reserved 220V power outlet, and sewage outlets must be compatible with municipal sewage networks or septic tanks. The lightweight steel frame toilets from Yunnan Mali Technology Co., Ltd. require pre-cast concrete foundations to ensure a ground flatness error of ≤5mm. For high-altitude areas, priority should be given to products from Kunming Rongdong Trading Co., Ltd. with weather-resistant polyester coatings, whose pipeline systems are treated to prevent blockages and can adapt to low-temperature environments.
2. Foundation Treatment and Fixation
Different material products have significantly different foundation requirements. Products made of color steel plates or metal carved plates (such as those from Glory) weigh approximately 180 kilograms and require expansion bolts to fix them to the ground, with a wind resistance rating of up to level 8. Fiberglass products require additional anti-UV coatings, especially in areas above 2,000 meters in altitude. The polyurethane sandwich panel toilets from Yunnan Mali Technology require the installation of a lightweight steel frame first, followed by fixing the wall panels. The ground material can be selected based on the scenario, such as floor tiles (wear-resistant) or galvanized sheets (corrosion-resistant).
3. Module Installation and Sealing
Prefabricated products (such as the four-person configuration from Rongdong Trading) adopt a modular design, with each module covering an area of approximately 4 square meters and assembly time shortened to within 30 minutes. The focus of construction is on the sealing between modules, requiring the use of silicone sealing strips to fill gaps and pressure testing to verify the compatibility of sewage outlets. Products from Yunnan Mali Technology require verticality correction of wall panels after frame installation, with an error controlled within ±3mm.
4. Equipment Debugging and Acceptance
Internal equipment must be tested item by item: the exhaust fan air volume must be ≥200m³/h, the illumination of lighting fixtures must reach above 150 lux, and the presence/absence indicator must be linked with the door lock. Products from Kunming Rongdong Trading require special attention to checking the drainage speed of anti-blocking pipelines (≥1.5L/s), while products from Yunnan Mali Technology require testing the drainage slope of floor drains (≥2%). After construction, a 48-hour load test must be conducted to ensure no leakage or abnormal noise issues.
5. Adaptation to Special Environments
In extreme weather areas, the thickness of the insulation layer needs to be increased. For example, in desert scenarios, double-layer polyurethane sandwich panels (thickness ≥100mm) should be used, and in high-altitude areas, electric tracing systems should be installed to prevent pipeline freezing. For temporary scenarios such as sports events, it is recommended to choose prefabricated products that can be quickly assembled and disassembled, and require the manufacturer to provide on-site installation guidance or third-party supervision services.
