Determination of Squat Positions in Mobile Toilets

The determination of squat positions in mobile toilets requires consideration of multiple factors, including usage scenarios, pedestrian traffic, design standards, user needs, available site area, and dimensional design. Details are as follows:

1. Usage Scenarios, Pedestrian Traffic, and Design Standards
The configuration of squat positions in mobile toilets varies significantly across different scenarios. Most parks adopt a basic model of '4 squats and 1 urinal' (4 squat positions with 1 W-shaped urinal). If the park is large or experiences high pedestrian traffic, the number of squat positions may increase to 5. High-end scenic spots may install separate urinals, but the core configuration remains centered around '4 squats and 1 urinal'. Pedestrian traffic is a key parameter: in ordinary parks, one squat position is set for every 3-5 people, while in high-traffic scenic spots, one is set for every 2-3 people. For women's restrooms, the calculation is based on the number of people in segments: for fewer than 100 people, one squat position is provided for every 15 people, and for more than 100 people, an additional position is added for every 30 additional people. For men's restrooms, one squat position is provided for every 25 people for fewer than 100 people, and an additional position is added for every 50 additional people for more than 100 people.

2. Pedestrian Traffic and Gender Ratio
It is necessary to clarify the location where the mobile toilet will be used (such as scenic spots, streets, schools, etc.) and dynamically adjust the number of squat positions based on pedestrian traffic. The ratio of male to female areas is typically 1:2, or separate unisex stalls can be installed to improve usage efficiency. For example, schools or factories may adjust the ratio based on gender distribution differences, while scenic spots need to prioritize meeting the needs of women.

3. Usage Needs of Different User Groups
Special user needs must be considered, such as installing a third restroom (for families and people with disabilities), a management room, a urinal room, or a rest area. For example, in children's activity areas, the height of sinks needs to be lowered, while in elderly activity areas, handrails need to be added; in母婴 (maternity and infant) scenarios, baby care stations need to be equipped. These functional rooms may occupy some space for squat positions, so they need to be comprehensively planned in the design.

4. Reserved Site Area and Installation Conditions
The mobile toilet should be slightly smaller than the reserved area to ensure smooth hoisting, especially when there are buildings on both sides. Before installation, a flat ground needs to be poured, and the area should not be smaller than the size of the toilet. If the site is limited, a modular design can be prioritized, meeting needs by combining multiple small units.

5. Dimensional Design Specifications
The independent space area for each squat position should be ≥1.5 square meters, with a length of 1-1.5 meters and a width of 0.85-1.2 meters; the depth of male urinals should be 0.75 meters, with a width of 0.7 meters and a spacing of 0.7-0.8 meters. The aisle width should be ≥1.3 meters (with a minimum of not less than 1 meter), the indoor net height should be >3.5 meters, and the height of the deep-squat partition should be ≥0.9 meters. These standards ensure comfort and safety in use, avoiding collisions or privacy breaches caused by cramped spaces.
