Jiyuan Outdoor Mobile Toilet Installation

The installation of outdoor mobile toilets in Jiyuan should adhere to a modular design concept, integrating climate and environmental protection requirements, and completing deployment through scientific construction plans, resource allocation, and process flows.

I. Construction Plan and Deployment Modular design is adopted, with the construction organization structure including key positions such as the project management department, technical, and safety teams, implementing a modular construction management model. The construction progress is divided into four stages:

1. Preliminary Preparation: Complete site surveys, technical briefings, and the arrival of materials and equipment;
2. Structural Construction: Conduct foundation works, welding of steel structural frames, and prefabrication of modular units;
3. Installation and Commissioning: After the main body is hoisted, install sanitary equipment (such as toilets and washbasins) and ventilation systems, and commission the foam sealing system;
4. Acceptance and Delivery: Inspect structural stability, equipment functionality, and environmental protection indicators to ensure compliance with usage standards.

II. Construction Preparation and Resource Allocation

1. Technical Preparation: Organize training for construction personnel to master steel structure welding process standards (such as weld quality grades), foam sealing system installation specifications (such as sealing requirements), and biological treatment equipment operation procedures.
2. Material Preparation:
   • Main Structure: Select lightweight and high-strength frame materials (such as aluminum alloy or galvanized steel pipes), fire-resistant wall panels, and waterproof roof panels;
   • Interior Decoration: Use anti-slip floor materials, antibacterial wall coatings, and integrated ceilings;
   • Sanitary Equipment: Equip with water-saving toilets, sensor-activated washbasins, and negative pressure ventilation systems.
3. Mechanical Equipment: Equip with truck cranes (for module hoisting), electric welders (for steel structure welding), cutting machines (for material processing), and level gauges (for foundation calibration).

III. Main Construction Processes

1. Foundation Works: Select concrete foundations or prefabricated ground anchors based on site conditions, ensuring a levelness error of ≤5mm;
2. Steel Structure Welding: Adopt full-weld processes, with welds requiring non-destructive testing;
3. Modular Unit Prefabrication: Complete the assembly of wall and roof components in the factory to reduce on-site construction time;
4. Main Body Hoisting: Use truck cranes to hoist modules in sequence and secure them with bolts;
5. System Commissioning: Test the foam generation volume of the foam sealing system, the air exchange rate of the ventilation system, and the degradation efficiency of the biological treatment equipment.

IV. Application Scenarios and Deployment Deploy differentially based on site conditions:

• Urban Parks: Set up temporary material storage areas and use detachable fences to isolate construction areas;
• Scenic Areas: Adopt prefabricated construction methods to minimize impact on the landscape;
• Construction Sites: Combine with temporary facility planning to reserve maintenance access and sewage discharge interfaces. Mobile toilet types include trailer-mounted (high mobility), standalone (suitable for decentralized deployment), and eco-friendly (equipped with biological treatment or sewage storage tanks), all of which do not require fixed sewer connections and are suitable for outdoor environments.
