Wuhan Monolithic Mobile Toilet
The Wuhan monolithic mobile toilet is a sanitary facility designed to meet the diverse and flexible deployment needs of urban areas. Its customization, rental, and practical applications all revolve around weather resistance, modularity, and scenario adaptability.
Customization Features: Materials and Structure Adapted to Wuhan's Climate
Wuhan experiences hot and rainy summers, cold and damp winters, and high air humidity. When customizing, priority should be given to weather-resistant and corrosion-resistant materials. High-density polyethylene (HDPE) is molded through rotational molding to form a seamless structure, effectively preventing moisture and rust. Fiberglass-reinforced plastic (FRP), a composite of resin and glass fibers, combines light weight with high strength, making it suitable for frequent lifting scenarios. The structure adopts a modular design, breaking down walls, roofs, and chassis into independent units that are prefabricated in factories and then assembled on-site. The chassis is pre-embedded with sewage discharge ports and fixing holes, while the walls are pre-reserved with ventilation and electrical channels. Connection methods include mortise-and-tenon snap-fit (for quick assembly and disassembly) and bolt fastening (for long-term fixation), facilitating later maintenance and module replacement. Internal components are configured according to the scenario: the flushing system can be either direct-discharge (relying on external piping networks) or recirculating water (with built-in biological treatment tanks, suitable for remote construction sites); squat toilets and sit toilets are adjusted according to the user group, with elderly individuals requiring the addition of handrails and non-slip floors; the ventilation system combines natural air ducts with solar-powered exhaust fans to reduce electricity dependence. Structural design requires load calculations, considering self-weight, user weight, wind load (Wuhan's basic wind pressure is 0.35 kN/m²), and dynamic forces during lifting. Transportation limits require a width of ≤2.5 meters and a height of ≤4 meters. The width of a single toilet is typically 1.2-1.8 meters, and the length is ≤2.4 meters. The internal space is optimized through roof slopes.
Rental Features: Self-Circulation and Modularity as Core Advantages
Rental-type monolithic mobile toilets are centered around "self-circulation" and "modularity," integrating storage tanks, flushing devices, and waste collection tanks internally, eliminating the need for external piping systems and enabling independent operation in areas without sewage networks, such as parks and construction sites. Waste treatment uses sealed collection tanks, with biological degraders or chemical deodorizers added to decompose solid waste and inhibit bacterial growth, requiring regular removal by professional equipment. The outer shell material is the same as that used in customization, being corrosion-resistant and UV-resistant, adapting to Wuhan's extreme climates. The bottom is equipped with adjustable feet for stable deployment on uneven terrains such as gravel or grass. The internal area is approximately 1.2 square meters, with compact space. Some upgraded models include sinks but require additional water for maintenance. Service quality affects the user experience, with differences among rental providers in cleaning standards, maintenance response times, and waste treatment frequencies. When rented for more than three days, a 40-liter collection tank can support approximately 50 uses under normal conditions, requiring more frequent maintenance in hot weather.
Practical Application: Solving Urban Toilet Access Challenges
The addition of mobile public toilets on Wuhan's Jianghan Road Pedestrian Street has effectively alleviated the toilet access challenges faced by tourists due to the street's length and insufficient restrooms, especially providing convenience for special groups such as the elderly, demonstrating the flexibility and practicality of monolithic mobile toilets in public event management.
