Installation of Mobile Toilets in Siming Park

The installation of mobile toilets in Siming Park should follow standardized procedures, combining site conditions and equipment types for scientific construction to ensure safety, hygiene, and functional compliance.

I. Preliminary Preparation and Site Assessment

1. Site Selection: The installation location should meet requirements for flatness and ventilation, avoiding areas near water pollution sources (such as sewage wells and septic tanks) to prevent cross-contamination. For waterless toilets, it is essential to assess whether the installation involves ancient tree roots or cultural relics to avoid excavation damage.
2. Equipment Inspection: Check the list of accessories, including the main frame, toilet bowls, fecal storage tanks, connectors, doors and windows, and electrical components, to ensure nothing is missing or damaged.
3. Standard Reference: According to the "Hygiene Standards for Mobile Toilets" (GB/T 21239-2023), confirm that indicators such as structural load-bearing capacity and material corrosion resistance meet requirements.

II. Main Body Installation and Fixation

1. Foundation Fixation: Place the main body of the mobile toilet at the designated location, using expansion screws to secure the bottom (for hard surfaces) or ballast blocks (such as sandbags or stones) for weighting (for soft surfaces) to prevent shaking or tipping.
2. Advantages of Waterless Toilets: No need to lay sewage pipes, reducing construction interference with the underground environment, especially suitable for ecologically sensitive areas or around ancient buildings.

III. Core System Installation and Commissioning

1. Sewage System:
   • Flushing Toilets: Connect the water inlet pipe, water tank, and flush valve to ensure stable water pressure; the connection of the sewage pipe should be sealed to prevent leakage.
   • Dry Toilets/Waterless Toilets: Fix the position of the fecal storage tank, install a diversion channel or biodegradation device to ensure centralized treatment of excreta.
2. Sealing Test: Apply silicone or use sealing rings at the connections between the toilet bowl and the fecal storage tank, as well as pipe joints, and test for water leakage during flushing.

IV. Auxiliary Facilities and Safety Configuration

1. Functional Accessories: Install doors and windows and adjust their opening and closing flexibility; add convenience facilities such as handrails, hooks, and paper towel holders; lay anti-slip mats to reduce the risk of slipping.
2. Electrical System: Connect the power for lighting and exhaust fans, test switches and leakage protection devices; if used at night, emergency lighting should be configured.
3. Appearance Customization: Choose外壳 (shell) styles such as antique, European, or minimalist according to the park's theme to coordinate with the surrounding landscape.

V. Acceptance and Maintenance

1. Safety Inspection: Confirm that the structure is stable, with no loose screws or sharp edges; post emergency contact information and usage instructions.
2. Hygiene Standards: Place deodorizers and disinfectants, clean up installation residues, and ensure no odors or stains.
3. Regular Maintenance: Develop a cleaning plan, check the capacity of the fecal storage tank (for dry toilets) or the flushing system (for flushing toilets), and replace worn parts in a timely manner.

Note: If the installation involves cultural heritage protection areas or ecologically sensitive areas, it is necessary to report to relevant departments in advance and prioritize the selection of waterless, low-noise equipment to minimize construction impact.
