Mobile Toilet Construction Plan

The construction of mobile toilets requires a combination of technical principles, structural design, and scenario-specific needs, with core steps including site selection, installation, acceptance, and optimization measures tailored to different scenarios. The specific plan is as follows:

I. Technical Principles and Structural Design Foundations The main frame of mobile toilets is constructed using lightweight color-coated steel plates (55mm thick), which are welded or bolted together to form a closed space, commonly in a container-style structure. The functional areas are clearly defined: the top is a waterproof roof; the middle section is equipped with flush toilets/foam-sealed urinals, sinks, and other sanitary facilities; the bottom features a sewage collection tank or municipal sewage connection, with some models integrating independent water tanks and power systems. The modular design supports the combination of multiple stalls, such as assembling multiple single-stall units into a multi-stall public toilet to meet different scale requirements.

II. Construction Process and Key Steps

1. Site Selection Requirements
   • The ground must be level and facilitate sewage discharge, avoiding low-lying flood-prone areas and the core areas of greenbelts (e.g., Nanchang requires a hard ground bearing capacity of ≥1.5 tons per stall).
   • Maintain a minimum distance of 5 meters from sensitive areas such as dining areas and entrances/exits, and at least 15 meters from residential buildings and schools.
2. Installation Specifications
   • Fix the structure using bolts or hoist it into place, connecting water and electricity (independent units do not require external connections).
   • For large-scale events, submit an application to the urban management department 7 working days in advance, providing a site plan, facility parameter table, and emergency plan.
3. Acceptance Standards
   • Check the sealing of the color-coated steel structure (with rubber sealing strips to isolate odors) and the effectiveness of rust prevention treatment to ensure suitability for outdoor environments.
   • Independent units require regular cleaning of the sewage collection tank, while municipal-connected units need inspection of sewage pipeline patency.

III. Scenario-Specific Optimization Plans

1. Outdoor Event Scenarios
   • Adopt a multi-stall modular combination, adding emergency lighting and ventilation devices; install sunshades and cooling spray devices in high-temperature weather.
2. Temporary Epidemic Prevention Points/Construction Sites
   • Use independent unit designs to reduce the risk of cross-infection, supporting regular disinfection and maintenance; equip remote areas with independent water tanks and power systems.
3. Urban Public Areas
   • Customize colors to harmonize with the surrounding environment, recommend a male-to-female stall ratio of 1:1.5, and ensure aisles are at least 0.8 meters wide; install reflective signs at night to ensure safe evacuation.

IV. Technical Highlights and Precautions

• Advantages: Rapid deployment (completed in a few hours), strong sealing, high durability, and good flexibility (supporting customization of volume and stall numbers).
• Maintenance Requirements: The lessee must provide daily cleaning services, including disinfection, garbage removal, and mosquito and fly control measures.
• Approval Process: For large-scale events, report to the public security department simultaneously and assign dedicated personnel to maintain on-site order.
