Installation of Mobile Toilets in Nanjing Park

The installation of mobile toilets in Nanjing Park requires a combination of structural design, process standards, and site selection specifications to ensure safety, functionality, and environmental harmony.

1. Main Structure and Material Selection

The main body of the mobile toilet adopts a high-strength steel structural framework, treated with hot-dip galvanizing or anti-rust coatings to enhance corrosion resistance and extend service life. The exterior is covered with eco-friendly composite materials, such as metal carved panels or aluminum-plastic panels, offering both lightweight properties and weather resistance. Internally, it is equipped with a complete water supply and drainage system (including a septic tank or direct sewage discharge interface) and ventilation and deodorization equipment (such as negative pressure fans and activated carbon filtration devices) to ensure user comfort and hygiene standards.

2. Installation Process and Safety Standards

1. Welding and Connection Nodes: Utilize CNC cutting and robotic welding technology to ensure component precision at the millimeter level, avoiding errors from manual welding. Key connection nodes are optimized through finite element analysis to enhance structural resistance to wind and snow loads, adapting to complex outdoor environments.
2. Bottom Support System: Choose adjustable feet (suitable for uneven ground) or roller devices (for frequent relocation) based on ground conditions. The support structure must pass load tests to ensure stability.
3. Modular Design: The toilet units adopt standardized modules for easy and quick assembly and disassembly, reducing on-site construction time.

3. Site Selection and Construction Specifications

1. Geological and Pipeline Conditions: Site selection requires an assessment of geological bearing capacity to avoid soft soil or sloped areas; simultaneously, confirm underground pipeline access points (such as water supply and sewage pipes) to ensure proper system operation.
2. Landscape Harmony: The exterior color and material should match the overall style of the park to avoid a jarring appearance. For example, using wood-grain or natural color finishes to blend into the green environment.
3. Environmental and Safety Standards: Construction must comply with the "Urban Public Toilet Design Standards", focusing on implementing anti-seepage measures (such as septic tank leak-proof layers), odor control designs (such as U-shaped traps), and sound insulation measures (such as double-layer partitions).

4. Acceptance and Maintenance

After installation, conduct airtightness and watertightness tests as well as load pressure tests to ensure no leaks and structural stability. Daily maintenance should regularly inspect the operating status of ventilation equipment, the smoothness of water supply and drainage pipes, and the integrity of the steel structure's anti-corrosion coating, promptly repairing any damaged components.
