Specifications for Mobile Toilets near Qionghai

The specifications for mobile toilets near Qionghai should be determined based on the usage scenario and functional requirements. Common standards are as follows:

I. Classification by Number of Toilet Cubicles

1. Single-cubicle Mobile Toilet

   • Floor Area: Approximately 1.2㎡ to 1.8㎡, with internal clear dimensions of length 1.2m to 1.5m × width 1.0m to 1.2m, and height 2.2m to 2.5m.
   • Suitable Scenarios: Temporary events, small construction sites, or areas with low foot traffic, meeting basic toilet needs.

2. Double-cubicle Mobile Toilet

   • Floor Area: Approximately 3㎡ to 4㎡, with length 2.4m to 3.0m, width 1.2m to 1.5m, and height 2.2m to 2.5m.
   • Suitable Scenarios: Medium-sized events, scenic spots, or temporary construction sites, helping to alleviate queuing pressure.

3. Multi-cubicle Mobile Toilet

   • Specification Expansion: For three or more cubicles, additional area is required, with each additional cubicle increasing the area by approximately 1.5㎡ to 2㎡. The overall length ranges from 3m to 6m, and the width ranges from 1.5m to 2.5m.
   • Suitable Scenarios: Large-scale events, transportation hubs, or long-term usage scenarios, requiring the design of the number of cubicles based on foot traffic.

II. Mobile Toilets with Special Functions

1. Accessible Toilet Cubicle

   • Internal Clear Dimensions: Must be no less than 1.8m × 1.4m, with an accessible ramp at the entrance that is wider than 0.8m.
   • Design Requirements: Comply with the 'Urban Public Toilet Design Standard' (CJJ 14-2016), facilitating wheelchair access and the use of assistive devices.

2. Baby Care Room/Third Toilet

   • Area Requirement: Generally no less than 4㎡, with a clear width of at least 1.5m.
   • Functional Configuration: Must include a baby changing table, safety seat, and accessible facilities to meet the needs of families or special groups.

3. Small/Medium/Large Mobile Toilets

   • Small: Dimensions 1m × 1.2m × 2.4m, with a capacity of 300-400 liters, suitable for space-constrained scenarios.
   • Medium: Dimensions 1.2m × 1.2m × 2.4m, with a capacity of 400-500 liters, balancing space and capacity requirements.
   • Large: Dimensions 1.5m × 1.5m × 2.4m, with a capacity of 500-600 liters, suitable for high-frequency usage scenarios.

III. Design Basis and Considerations

1. Industry Standards: Refer to the 'Urban Public Toilet Design Standard' (CJJ 14-2016) to ensure specifications meet hygiene, safety, and accessibility requirements.
2. Local Adjustments: In the Qionghai area, design should be optimized based on climatic characteristics (such as moisture resistance and ventilation) and usage frequency, for example, by increasing the capacity of the sewage system or selecting corrosion-resistant materials.
3. Functional Matching: Choose specifications based on actual needs to avoid over-design or insufficient capacity, for example, prioritizing the configuration of accessible and baby care facilities in scenic spots.

The above specifications are general standards, and specific projects should be comprehensively decided based on site conditions, budget, and usage cycle.
