Movable Public Toilet Specifications

The specifications of movable public toilets vary depending on their type, design, and functional requirements, commonly covering aspects such as dimensions, structure, materials, and sewage treatment methods.

I. Basic Dimensional Specifications The size range of single-occupancy movable toilets typically includes a length of 1.1 to 1.5 meters, a width of 1 to 1.2 meters, and a height starting from 2.2 meters. These designs prioritize compactness and are suitable for spaces with limited room. Multi-occupancy movable toilets expand in size based on the number of occupants they can accommodate; for example, a double-occupancy toilet can be up to 6.8 meters long, offering more spacious interiors that can be configured with individual stalls or shared facilities. Accessible toilets require additional consideration for wheelchair access, with door widths needing to comply with relevant standards to ensure unobstructed entry and exit for wheelchairs, with specific dimensions to be executed according to national standards.

II. Frame Structure and Materials The frame structure is welded using national standard steel, with channel steel or I-beams commonly used at the base to enhance load-bearing capacity, and square steel for columns to ensure overall stability and meet lifting requirements. The selection of wall materials focuses on corrosion and fire resistance, with common options including color-coated steel plates, fiberglass-reinforced plastic, stainless steel, and metal carved panels. These materials are not only durable but also have a service life of over 20 years, adapting to complex outdoor environments. For instance, color-coated steel plates are lightweight and cost-effective, while stainless steel offers superior corrosion resistance, suitable for high-humidity or coastal areas.

III. Sewage Treatment Methods and Space Adaptation The sewage treatment method directly affects the internal space design, with common types including:

1. Water-flush Type: Requires the configuration of a water tank and sewage pipes, with internal layouts needing to reserve space for pipe installation, suitable for locations with a water supply.
2. Waterless Suction Type: Uses a vacuum pump to suction waste, requiring no large amount of water but necessitating regular cleaning of the fecal storage tank, with space design needing to facilitate equipment maintenance.
3. Recirculating Water-flush Type: Adopts biodegradation technology to treat sewage, achieving water resource recycling, with internal integration of filtration and disinfection devices, offering high space utilization.
4. Dry Packing Type: Uses biodegradable bags to collect waste, requiring no water source or sewage system, with a simple structure suitable for water-scarce or temporary use scenarios.

IV. Special Function Adaptation In addition to door width requirements, accessible toilets need to be equipped with handrails, low-positioned sinks, and other facilities internally, with space layouts needing to reserve a turning radius for wheelchairs. Some high-end models are also equipped with emergency call systems and ventilation equipment to further enhance usability.

In conclusion, the specifications of movable public toilets need to be designed by comprehensively considering functional requirements, usage scenarios, and material characteristics to ensure practicality, safety, and durability.
