Linxia Mobile Single Toilet

The Linxia mobile single toilet is a mobile sanitation facility centered around modular design, enabling rapid assembly through standardized components. It is suitable for quick deployment in temporary events or areas with complex terrain.

I. Structural Units and Material Characteristics

1. Frame: Made of Q235 carbon structural steel, welded and shaped, with hot-dip galvanizing on the surface (zinc layer ≥ 85 microns), featuring anti-corrosion and detachable properties. The lightweight steel design keeps the overall weight manageable, facilitating transportation and repeated use.
2. Wall Panels: Composed of aluminum alloy composite panels or fiberglass panels, with a thickness of 5-8 millimeters. The core material is polyurethane foam (density 45 kg/m³, thermal conductivity ≤ 0.022 W/(m·K)). The surface anti-corrosion coating enhances weather resistance, while the polyurethane core provides good thermal insulation, adapting to temperature variations.
3. Roof: Designed with a single slope, it has reserved ventilation duct interfaces for easy connection to axial fans built into the walls or roof-mounted passive ventilators, forming a ventilation system that combines natural convection with mechanical assistance.
4. Internal Equipment:
   • Sanitary Components: Stainless steel squat toilets and 4.5-liter water-saving tanks (with delayed self-closing flush valves, flushing time approximately 8 seconds).
   • Ventilation System: Passive ventilators work in tandem with axial fans to ensure air circulation.
   • Lighting System: 12-watt LED panel lights, automatically controlled by photosensitive elements to reduce energy consumption.

II. Assembly Process and Connection Technology

1. Assembly Sequence: From bottom to top, complete the positioning of the steel chassis (pre-welded sewage pipe对接法兰), installation of columns and support beams (fixed with galvanized bolts), fitting of wall panel modules (waterproof sealing strips + slots), and connection of roof modules (hoses + stainless steel clamps).
2. Connection Mechanisms:
   • Frame Connection: Male and female tenons with locking pins allow for ±3-degree angle adjustments to accommodate slight ground unevenness.
   • Panel Connection: Hidden hook systems (hook spacing 30 centimeters) enable quick assembly and disassembly.
   • Pipe Connection: Quick-connect fittings with built-in rubber seals are rotated 90 degrees to achieve sealing, simplifying the installation process.

III. Advantages of Modular Structure

1. Ease of Assembly and Disassembly: A single person can complete the entire disassembly within 4 hours, and all components can be loaded into a standard truck for transportation, reducing logistics costs.
2. Environmental Adaptability: No concrete foundation is required; it can be deployed after ground leveling. The chassis height is adjustable (15-40 centimeters), accommodating terrains with slopes ≤ 5 degrees or ground elevation differences.
3. Ease of Maintenance: Damaged components can be replaced individually (e.g., replacing a wall panel takes about 20 minutes) without requiring complete disassembly, extending the facility's service life.

IV. Application Scenarios
In the Linxia area, this toilet unit can quickly respond to the needs of temporary events (such as exhibitions and construction projects), taking as little as 90 minutes from arrival on-site to being put into use, significantly improving emergency response efficiency.
