Design and Construction of Mobile Toilets in Wuhan

The design and construction of mobile toilets in Wuhan need to be comprehensively considered from multiple aspects such as design concepts, material selection, technological innovation, and construction processes.

Design Highlights

1. Modular Design and Scene Adaptation
   Adopt a light steel keel frame main structure with a配套 (matching) environmental protection treatment system to meet the diverse needs of scenic spots, construction sites, event venues, and other scenarios. The functional zoning should clearly define the ratio of men's toilets, women's toilets, and accessible toilet stalls. The diameter of the sewage pipe is 114mm, and the routing of the PPR water outlet pipes should be planned in advance.
2. Material Selection
   The box body materials are mainly high-strength and corrosion-resistant composite materials, such as fiberglass reinforced plastic or color-coated steel plates. The main keels are made of 80×80×3.0mm galvanized square tubes. The walls use 10mm-thick metal carved panels (with a fire rating of B1). The floor is laid with 2.5mm-thick non-slip patterned aluminum plates, and the waterproof layer is made of 4mm-thick SBS modified asphalt waterproof membranes (with a heat resistance of ≥80℃). The sanitary ware should be equipped with water-saving ceramic squatting pans (with a flush volume of ≤6L per time).
3. Technological Innovation and Humanization
   Apply environmental protection technologies such as microbial degradation and vacuum self-priming to reduce odors. The internal facilities include lighting, ventilation, handrails, hooks, etc. Some models are equipped with solar power supply systems, intelligent induction flushing devices, and door lock systems that display the usage status.

Construction Process

1. Construction Preparation
   • Technical Preparation: Deepen the drawing design, confirm the main structure dimensions (standard single unit: 1.37m×1.2m×2.4m) and equipment installation nodes. Prepare a technical disclosure manual, clarify the steel structure welding parameters (welding rod E4303, current 90 - 110A) and waterproof acceptance standards (lap width ≥100mm).
   • Material Preparation: Purchase main keels, wall materials, etc. according to the design requirements and inspect their specifications and parameters.
   • On-site Preparation: Survey the site flatness (error ≤50mm), confirm the power access point (220V single-phase power, capacity ≥2kW) and the safe distance from underground pipelines (≥1.5m). Set up material storage areas, processing areas, and safety protection areas.
2. Main Structure Construction
   • Foundation Construction: Compact the plain soil (compaction coefficient ≥0.93), pour a C20 concrete cushion (thickness 100mm, with bidirectional steel bars), and embed M16 anchor bolts. Pre-embed DN110 UPVC sewage pipes (with a slope of 3‰) and set up sedimentation wells and anti-odor traps.
   • Structural Installation: Weld the bottom frame (100×100×3.0mm channel steel), install columns (80×80mm square tubes) and the top grid load-bearing structure (30×60×2.0mm square tubes). The walls adopt a three-layer structure of calcium silicate board + polyurethane insulation layer + metal carved panel, and the roof is laid with SBS waterproof membranes (lap width 100mm).
