Dazu Floor Mobile Toilet Design

The design of mobile toilets on floors in Dazu should incorporate core principles such as modularity, drainage adaptation, structural safety, functional self-sufficiency, and environmental integration. The specific plan is as follows:

1. Modularity and Spatial Adaptability

The mobile toilet adopts a standardized unit design, decomposing functions such as toilet use and washing into independent modules that are connected via detachable interfaces. In floor environments, linear or circular layouts can be adopted according to the shape of the space (such as corridors and corners), and the levelness can be quickly adjusted through hydraulic leveling legs to accommodate slight ground inclinations. Modular design facilitates transportation and reassembly, making it particularly suitable for temporary or flexible demand scenarios.

2. Drainage and Pipeline Handling Solutions

• Same-floor drainage: If the floor uses a sunken-floor drainage system, pipelines can be buried within the raised floor, and their positions can be adjusted by lengthening or shortening them to reduce the risk of blockages.
• Inter-floor drainage: If pipelines pass through the floor slab, adjustments can be made using toilet position shifters (with a moving distance ≤ 2 meters) or by converting floor drains to wall drains. Wall-mounted toilets require the construction of false walls to hide pipelines, which can be combined with niches to increase storage space. In extreme cases, it may be necessary to negotiate with the downstairs occupants for sewage pipe modifications, but this requires an assessment of property management rules and the risks associated with neighborly relations.

3. Structural Safety and Lightweight Design

Mobile toilets on floors need to balance transportation vibrations and long-term load-bearing. It is recommended to use lightweight yet high-strength materials (such as fiberglass-reinforced plastic and aluminum alloy honeycomb panels) to construct the box body, and employ spatial truss principles for the internal framework to balance self-weight and load-bearing capacity. For the floor material, vinyl flooring is recommended, with its seams hot-welded to form a seamless surface, preventing water seepage and extending service life.

4. Functional System Self-Sufficiency

• Water circulation: An integrated closed-loop water treatment system is adopted, achieving single-tank water storage that supports 200 person-times of use through three-stage filtration and ultraviolet disinfection. Gray water is recycled for toilet flushing, reducing water consumption.
• Waste treatment: Vacuum collection technology is used to compress solid waste to 30% of its original volume, or biodegradable equipment is employed to reduce the frequency of cleanups.
• Energy supply: A hybrid power supply of photovoltaic films and micro wind turbines is used, with backup lithium battery packs ensuring operation during cloudy or rainy days, achieving energy self-sufficiency.

5. Environmental Integration and User Experience Optimization

• Ventilation and temperature control: Silent exhaust fans on the top and air inlets on the side walls create convection. In high-temperature areas, phase-change material insulation layers are added, while in cold environments, underfloor heating pipelines and heat recovery systems maintain a comfortable temperature.
• Barrier-free design: The width of the washbasin is controlled between 40-50 centimeters, and necessary operating space is reserved in the toilet area to ensure compliance with ergonomic standards.

Precautions: Before design, it is necessary to confirm the drainage type (same-floor/inter-floor) and strictly comply with property management regulations to avoid damaging the main drainage riser. For long-term fixed use, the durability of materials and maintenance costs should be evaluated.
