Installation of Mobile Toilets in Rural Areas of Dingxi

The installation of mobile toilets in rural areas of Dingxi requires adaptive design and modular processes tailored to local climate and terrain characteristics. Key points are as follows:

1. Structural and Material Adaptability The Dingxi region experiences significant temperature variations between day and night, with winter temperatures dropping as low as -20℃. Additionally, the Loess Plateau has issues with collapsible foundations. The main body of the mobile toilet should be constructed with a steel frame, paired with anti-corrosion color-coated steel plates, stainless steel, or FRP composite panels to ensure corrosion resistance and structural stability. The insulation layer of the toilet body should be at least 50mm thick, featuring a double-layer design of rock wool and aluminum foil reflective layer. The sewage pipeline should be equipped with an electric tracing system to prevent freezing at low temperatures. For collapsible foundations, foundation treatment options include sand and gravel compaction, concrete piers, or screw piles to ensure wind and earthquake resistance meeting an 8-degree seismic fortification intensity requirement.

2. Functional Module Selection Functional modules should be configured based on usage scenarios:

• Rural human settlement environment improvement: Prioritize standard or sink-equipped models, featuring water-saving flushing systems (reducing daily water consumption by 60%) or eco-friendly waterless models (with microbial treatment modules) for both hygiene and environmental protection;
• Traffic arteries/construction camps: Require corrosion-resistant sewage tanks (with a capacity of at least 1.2m³), explosion-proof lighting, and vacuum collection systems to accommodate high-intensity usage;
• High-altitude cold regions: Must include vacuum suction models with electric tracing sewage pipelines, with some products supporting solar power to address sewage disposal challenges in low-temperature environments.

3. Installation Process and Cycle A modular assembly approach is adopted, with standardized interface designs facilitating quick assembly and disassembly. The overall dimensions during transportation comply with road regulations. Upon arrival at the installation site, the toilet can be deployed using hydraulic devices, with each installation cycle controlled within 3 hours without the need for heavy machinery. Companies like Guting Metal Products provide installation drawings and foundation construction guidance, with a production cycle of 7-10 working days.

4. Localized Service Guarantee Choose companies that have passed the GB/T 18045-2021 standard and are registered in Gansu Province to ensure compliance. Prioritize companies with localized maintenance teams (response time ≤ 4 hours), supporting WeChat mini-program repair requests and regular delivery of consumables to reduce long-term maintenance costs. Recommended suppliers include Guting Metal Products, Jinmuhe Metal Products, etc.

5. Typical Application Case References

• The Tongwei County Spring 2025 Township Market Project adopted the GTS-600 series (304 stainless steel squatting positions + anti-slip floor rubber + LED energy-saving lights) to accommodate high foot traffic at the market;
• The Wuyuan County Wuzhu Town Eco-Tourism Demonstration Village implemented the JM-ECO series (SMC molded panels + biodegradation modules) to achieve zero sewage discharge and low maintenance, aligning with the eco-tourism positioning.

The plan requires further adjustment of parameters based on the specific village's altitude, sandstorm level, and municipal pipeline network coverage.
