Xiangyang Small Mobile Toilet Design

The design of small mobile toilets in Xiangyang should adhere to the principles of 'applicability first, hygiene compliance, economic efficiency, and environmental friendliness'. It should take into account the characteristics of the subtropical monsoon climate and site conditions, with a particular focus on enhancing waterproofing, ventilation, and thermal insulation performance. The specific design points are as follows:

I. Space Configuration Standards

1. Toilet Cubicle Dimensions: Each cubicle should be 1.1m wide, 1.2m deep, and have a clear height of 3.2m. The corridor width for single-row layouts should be 1.3m to ensure smooth passage.
2. Toilet Cubicle Ratio: Male and female toilet cubicles should be configured at a ratio of 1:1.5, with a 50% increase in female cubicles to alleviate usage pressure during peak periods. Accessible toilet cubicles should be no less than 1.8m × 1.5m in size to meet the needs of special populations.
3. Auxiliary Spaces: The management room should have an area of 6㎡, and the tool room should have an area of 2㎡. Both should be equipped with independent entrances and exits that are 1.2m wide to facilitate equipment maintenance and personnel management.

II. Material Selection and Performance Optimization

1. Wall System:
   • The exterior wall should use metal carved panels (0.3mm aluminum-magnesium alloy panel + 50mm thermal insulation rock wool + 0.2mm galvanized back panel), with a thermal conductivity coefficient of ≤0.04W/(m·K) and a weather resistance rating of C4, balancing thermal insulation and corrosion resistance.
   • The partition should use photochromic acrylic panels (12mm thick), which transition from transparent to frosted within 30 seconds under ultraviolet light, protecting privacy while maintaining good light transmission.
2. Roof and Floor:
   • The roof should have a pitched design (25° slope) and use colorful formed aluminum panels (0.8mm thick) + 50mm thermal insulation rock wool, with a fluorocarbon coating on the surface for rust prevention. The floor should be laid with anti-slip tiles (300×300mm, friction coefficient ≥0.6), with a base layer of 100mm thick C25 concrete pouring to ensure drainage and anti-slip performance.
3. Functional Materials:
   • For wall waterproofing, use 1.8m high JS composite waterproof coating (1.5mm thick), and for the floor, use flexible polyurethane coating (elongation ≥400%, total thickness 2.0mm) for dual protection against heavy rain in summer.
   • For cold bridge treatment, attach 30mm thick XPS thermal insulation panels to the exterior of window frames to reduce heat loss in winter.

III. Construction Process and Customized Services

1. Foundation Construction: After site leveling, lay a 200mm thick graded gravel cushion, pour C30 concrete independent foundations (800×800×300mm), and embed M16 anchor bolts to ensure structural stability.
2. Main Body Installation: The steel structure frame should be welded using 50×50×3mm square steel. Wall panels should be fixed with self-tapping screws, and the panel joints should be filled with PU foam and then sealed with weather-resistant adhesive to enhance sealing performance.
3. Customized Options: Cangzhou Hengtai Environmental Sanitation Equipment Co., Ltd. offers products such as ht-579 and ht-135 models, with specifications of 1200×1500×3000, suitable for temperature ranges from -30℃ to 40℃. The materials can be selected from color steel plates or metal carved panels to meet different scene requirements.
