Nanchuan Mobile Toilet Design

The design of mobile toilets in Nanchuan requires a comprehensive consideration of core elements such as the separability of functional modules, the load-bearing system, and the sewage discharge path, along with customized design based on scenario-specific needs.

Separability of Functional Modules and the Base Ground

The core advantage of mobile toilets lies in the temporary and reversible integration of their functional modules with the base ground. The design should integrate functions such as toileting, temporary storage, ventilation, and subsequent treatment interfaces into independent functional packages. For example, through modular design, storage tanks and ventilation systems can be integrated into the toilet body, ensuring the entire unit can be quickly disassembled, relocated, and redeployed. This design should avoid fixed connection structures and use detachable bolts or clips for fixation to accommodate temporary installation needs on different terrains.

Load-Bearing System Design

The load-bearing system must balance structural strength and durability:

• Chassis Frame: Galvanized steel or corrosion-resistant treated steel should be used, with structural optimization through mechanical calculations to prevent deformation during lifting and transportation. For example, reinforcing ribs or cross-bracing can be designed at the bottom of the toilet body to distribute pressure.
• Toilet Body Material: Early designs primarily used metal plate splicing, but now fiberglass-reinforced plastic (FRP) and other composite materials are widely used. FRP, through integral molding or modular assembly, achieves seamless, waterproof, and corrosion-resistant properties, while integrating thermal insulation, sound insulation, and fire resistance through multi-layer composites (interior panels, insulation layers, exterior panels). For example, in northern regions, the thickness of the insulation layer needs to be increased to cope with low temperatures.

Closed and Conversion Solutions for Sewage Discharge Paths

Choose appropriate sewage discharge methods based on usage scenarios:

• Storage Type: A large-capacity storage tank is installed at the bottom of the toilet body, with regular removal by suction trucks. This is suitable for remote areas or short-term usage scenarios but relies on removal services.
• Biodegradable Type: Microbial agents are added to decompose waste into gas and water, reducing the frequency of removal. Attention should be paid to the impact of ambient temperature on the activity of the microbial agents; for example, heating devices may be required in low-temperature environments.
• Chemical Treatment Type: Chemical agents are used for disinfection and decomposition, suitable for scenarios with high hygiene requirements or scarce water resources, such as medical emergency toilets.
• Recirculating Water Flush Type: A small-scale sewage treatment system is equipped to filter and disinfect flushing water for reuse, saving water but with higher costs, suitable for long-term fixed usage in scenic spots or construction sites.

Scenario-Based Customized Design

Taking Tingjia Metal Products Co., Ltd. as an example, its prefabricated toilets are designed for scenarios such as municipal facilities, scenic spots, and construction sites. They use high-quality steel and environmentally friendly interior materials, ensuring both strength and weather resistance through standardized processes (cutting, welding, rust prevention treatment, etc.), and provide free on-site measurement, customized design, and installation services. For example, toilets in scenic spots can incorporate bionic design, while those on construction sites can be reinforced with dust and impact resistance features.
