Specifications for Mobile Toilets in Qionghai Scenic Area

The specifications for mobile toilets in Qionghai Scenic Area are based on the 'Design Code for Mobile Toilets in Tourist Attractions' (GB/T50344-2017) and general standards, covering basic types, functional specifications, specific requirements for scenic areas, and general design standards, as detailed below:

I. Basic Types and Dimensions

1. Single-Occupancy (Standalone): Minimum dimensions are 1.2 meters in length, 1 meter in width, and 2.2 meters in height, with standard dimensions being 1.5 meters in length, 1.2 meters in width, and 2.3 meters in height, suitable for wheelchair assistance.
2. Double-Occupancy (Two Toilets): Standard dimensions are 2.5 meters in length, 1.5 meters in width, and 2.3 meters in height, including two compartments and a shared sink, suitable for small to medium-sized scenic areas.
3. Multi-Unit (4-6 Toilets): Suitable for large events or high-traffic scenic areas, with lengths ranging from approximately 5 to 8 meters, widths of 2 meters, and heights of 2.3 meters, enhancing efficiency through modular design.

II. Functional Specifications

1. Accessible Toilets: At least 2 meters in length, 1.5 meters in width, and 2.4 meters in height, requiring a 1.5m x 1.5m wheelchair turning space, grab bars at a height of 0.85-0.9 meters, non-slip flooring, and an entrance ramp with a slope of ≤1:12 to ensure safe use by individuals with disabilities.
2. Baby/Family Toilets: Approximately 2.2 meters in length, 1.8 meters in width, and 2.4 meters in height, equipped with baby changing tables, child-sized toilets, and safety grab bars to meet the special needs of family visitors.

III. Specific Requirements for Scenic Areas

1. Location and Layout: Should be located near tourist roads or activity areas, with the number and spacing of toilet stalls dynamically adjusted based on visitor flow to avoid overcrowding or excessive dispersion, enhancing convenience of use.
2. Functional Configuration: The ratio of male to female toilet stalls is typically 3:2 or 3:1, equipped with standard facilities such as squat toilets, urinals, sinks, and mirrors; smart technologies include sensor-activated flushing and three-dimensional deodorization systems (odor concentration < 10ppm), and environmental technologies include solar power and water-saving fixtures (per capita water usage ≤ 30ml).
3. Aesthetic Harmony: Utilize eco-friendly materials (such as anti-corrosion wood and ecological panels), with colors and designs integrating local cultural characteristics, and a building ventilation-to-light area ratio of ≥1:6, balancing practicality and aesthetics.

IV. General Design Standards

1. Ergonomics: Toilet stall widths should be no less than 0.9 meters, and sink heights between 0.8-0.9 meters, ensuring comfort of use.
2. Materials and Environmental Protection: Use lightweight, high-strength composite materials (such as fiberglass), with a drainage system designed at the bottom, and waterproof materials for walls, extending service life and reducing maintenance costs.
3. Industry Standards: Must comply with the 'Design Code for Urban Public Toilets' (CJJ 14-2016) and local environmental requirements, ensuring safety and compliance.

By combining functionality and environmental protection, these specifications not only meet the needs of visitors but also enhance the image of the scenic area, serving as the core basis for the design of mobile toilets in Qionghai Scenic Area.
