Installation of Outdoor Mobile Toilets in Xinjiang

The installation of outdoor mobile toilets in Xinjiang requires a systematic approach covering foundation treatment, structural assembly, functional system configuration, and environmental protection. The specific steps are as follows:

1. Foundation Treatment: Adapt to Local Conditions to Ensure Stability
Xinjiang has complex geological conditions, necessitating targeted adjustments in foundation treatment. In sandy soil areas, a combination of concrete bases and ground anchors should be used to prevent structural displacement. In permafrost zones, the foundation should be deepened to below the permafrost limit to avoid settlement caused by freeze-thaw cycles. In saline-alkali lands, the foundation platform should be elevated, using non-metallic isolation pads or aluminum-magnesium-zinc-based color-coated steel plates, and ensuring that the depth of anchor points meets standards. For example, the edge of the Taklimakan Desert often adopts a concrete base + ground anchor solution, while the permafrost area in Altay requires extending the foundation depth to more than 2 meters underground.

2. Structural Assembly: Modular Design Enhances Efficiency and Performance

• Panel Connection: Color-coated steel wall panels use hidden fastening technology, connected through internal slots, with external seams sealed with waterproof adhesive strips; tongue-and-groove connections create a thermal break effect, reducing heat conduction.
• Roof Design: The roof has a slight curve to improve load-bearing capacity and direct rain and snow flow; the drainage slope is adjusted according to precipitation, with a gentle slope in arid areas and an increased slope in snowy areas, equipped with anti-snow accumulation guards.
• Pipe System: Sewage, ventilation, and water supply pipes adopt a split design, prefabricated into independent modules in the factory and connected on-site; high-density polyethylene is selected as the material to prevent leakage caused by thermal expansion and contraction.
• Connection Method: The entire structure uses bolt connections, with elastic seals added to compensate for temperature-induced deformation, ensuring airtightness.

3. Functional System Configuration: Adapt to Xinjiang's Climate and Resource Conditions

• Ventilation System: Utilizing the principle of convection circulation, adjustable louvers are installed at high points on the wall panels, combined with Xinjiang's wind resources to create negative pressure ventilation; exhaust ducts are equipped with sand-proof filters and reserved cleaning channels.
• Water-Saving System: The flushing system uses the principle of pressure difference, with感应式 (inductive) flow-limiting devices on handwashing basins, controlling single-use water volume to within 0.5 liters; some models recycle handwashing wastewater for secondary flushing, achieving a water-saving rate of 70%.
• Waste Treatment: Solid-liquid separation devices combine biological degradation with physical filtration, adding microbial agents to solids for accelerated decomposition, and filtering liquids through multiple stages for non-potable use, reducing the frequency of emptying.

4. Environmental Protection and Thermal Optimization: Balancing Ecology and Energy Efficiency

• Environmental Protection Measures: The coating on color-coated steel plates uses photocatalytic materials to decompose pollutants; solar panels are installed on the roof for power supply; construction in ecologically fragile areas follows the principle of minimal disturbance to avoid crushing vegetation.
• Thermal Performance: The color-coated steel plate sandwich is filled with 150mm rock wool (exceeding the standard for ordinary mobile homes), with windows using double-glazed units + adjustable louvers for summer shading and ventilation and winter solar heating, reducing energy consumption by about 40%.
• Circuit Safety: Lighting circuits are laid in dedicated cable trays to prevent short circuits caused by condensation.
