Hubei Single-Unit Mobile Toilet
Customization of single-unit mobile toilets in Hubei requires comprehensive consideration of materials, structure, internal component configuration, and process specifications. The specific key points are as follows:
Material selection should be adapted to the climatic environment
Wuhan has a subtropical monsoon climate, with hot and rainy summers, cold and damp winters, and high air humidity. The materials need to have strong weather resistance and corrosion resistance. High-density polyethylene (HDPE) forms a seamless structure through one-time rotational molding, effectively blocking moisture penetration and preventing the rusting of internal metal frames, making it suitable for long-term outdoor use. Fiberglass-reinforced plastic (FRP) is composed of resin and glass fibers, featuring lightweight and high strength. Its wall thickness and surface treatment processes (such as adding an anti-ultraviolet coating) can be adjusted to adapt to frequent lifting or mobile scenarios. For example, toilets near rivers or high-rise buildings should prioritize the use of FRP materials with strong wind-resistance performance.
The structure adopts a modular design
During customization, functional units are divided into modules such as walls, roofs, chassis, door panels, and internal fittings, supporting factory prefabrication and rapid on-site assembly. The chassis module needs to have pre-embedded sewage pipe interfaces and fixed bolt holes to ensure seamless connection with municipal sewage networks or biological treatment tanks. The wall module has reserved ventilation windows and electrical wiring channels, with connection methods including mortise-and-tenon snap-fit (suitable for short-term events) and bolt fastening (suitable for long-term fixed locations). Modular design can reduce long-term maintenance costs by more than 30% and facilitate local replacement.
Internal components are combined according to needs
- Flush system: The direct-discharge type relies on external sewage pipe networks and is suitable for venues with fixed pipelines such as parks and scenic spots. The recirculating water type has a built-in biological treatment tank that degrades feces through microorganisms, making it suitable for remote construction sites or temporary events without municipal sewage.
- Toilet selection: For elderly groups or medical stations, it is necessary to equip them with toilet seats with handrails and non-slip floors. For ordinary scenarios, squat toilets can be selected to save space.
- Ventilation system: Considering the high summer temperatures in Wuhan, priority should be given to a combination of natural air ducts (such as top louvers) and solar-powered exhaust fans to reduce power dependence and ensure internal air circulation.
The customization process needs to be strictly regulated
- Load calculation: It is necessary to consider the self-weight, user weight (calculated based on 5 people using it simultaneously), wind load (the basic wind pressure in Wuhan is 0.35 kN/m²), and lifting dynamic forces to ensure that the connection nodes between the walls and the roof pass wind-resistance tests.
- Transportation limits: For road transportation, the width should be ≤ 2.5 meters and the height should be ≤ 4 meters. Therefore, the width of the toilet is usually controlled between 1.2 - 1.8 meters, the length ≤ 2.4 meters, and the height is reduced while ensuring an internal clear height (≥ 2.1 meters) through roof slope design (such as a 15° - 30° pitched roof).
Through material adaptation, structural optimization, and functional customization, single-unit mobile toilets in Hubei can achieve efficient, durable, and customized production that meets scenario requirements.
