Yulin Mobile Toilet Design
The design of mobile toilets in Yulin needs to take into account humanization, environmental protection, environmental adaptability, modular functionality, and material and structural optimization. The specific key points are as follows:
1. Humanized and Comfortable Design
Mobile toilets in Yulin should focus on the needs of tourists to optimize the user experience. Internally, they should be equipped with ergonomic squatting and standing positions, and accessible restrooms should be set up to meet the needs of different groups of people. Hand-washing facilities should be equipped with sensor faucets to reduce contact contamination; the ventilation system should adopt a combination of natural ventilation and mechanical exhaust to ensure air circulation and avoid the accumulation of odors. In addition, sufficient toilet paper, hand dryers, or disposable hand towels should be provided, and details such as hooks and storage platforms should be set up to enhance convenience of use.
2. Environmental Protection Design
Environmental protection is the key to the design of mobile toilets in Yulin. In terms of material selection, priority should be given to recyclable Q235B steel frames and polyurethane sandwich panels to reduce resource consumption. In terms of water-saving technology, vacuum water-saving systems can be applied to reduce water consumption through negative pressure suction, making the daily water consumption ≤ 500L, which is much lower than that of traditional toilets. Fecal treatment should comply with the "Hygienic Requirements for the Harmless Treatment of Feces" (GB 7959-2012), using biodegradation or septic tank technology to avoid polluting the soil and water sources.
3. Design for Adapting to Extreme Environments
Yulin has strong winds and sand and low temperatures, so the toilets need to have wind and sand resistance and low-temperature resistance. Structurally, a design with a wind resistance level of ≥12 should be adopted, and the steel frame should be reinforced and fixed with anchor bolts to prevent strong winds from overturning it. The exterior walls are made of polyurethane sandwich panels, which have excellent thermal insulation properties. Coupled with broken bridge aluminum insulated glass windows, they can withstand temperatures as low as -35°C and avoid pipe freezing. The door and window seals should use fire-resistant sealants to prevent sand and dust from entering and improve thermal insulation.
4. Modular and Functional Design
Modular construction can shorten the construction cycle and reduce transportation costs. The standard single toilet has dimensions of 5m × 3m × 2.8m, including 3 squatting positions (with a male-to-female ratio of 1:1.5), 1 accessible restroom, and 1 management room, with clear functional divisions. In addition, customized antique-style environmentally friendly art public toilets can be designed according to needs, such as 2 squatting toilet compartments, 1 third restroom (for families or people with disabilities) and 1 management room, with an appearance that integrates local cultural elements and supports personalized style customization.
5. Material and Structural Optimization
The main structure adopts a Q235B steel frame, which has high strength and corrosion resistance; the wall panels use polyurethane sandwich panels, which have both thermal insulation and fire resistance (with a fire resistance rating of Class A). The doors and windows are made of broken bridge aluminum insulated glass windows, which have significant thermal insulation and sound insulation effects. Fire-resistant sealants are used at the connection points to prevent air leakage and water seepage and extend the service life. The overall design takes into account stability, durability, and comfort to meet the needs of the complex environment in Yulin.
