Gannan Park Mobile Toilet Installation

The installation of mobile toilets in Gannan Park must follow standardized procedures to ensure safety, hygiene, and functional compliance. The specific steps are as follows:

1. Preliminary Preparation

• Site Selection: The installation location must be flat and well-ventilated, and away from water pollution sources (such as rivers and lakes, at least 50 meters away) to prevent water contamination.
• Site Clearance: Remove obstacles such as debris and stones from the site to ensure a level and stable ground for subsequent fixation.
• Equipment Inspection: Check the equipment parts list to confirm that the main frame, toilet bowl, fecal storage tank, connectors (such as screws and seals), water supply/drainage components (water tank, water pipes), etc., are complete and undamaged.

2. Foundation Fixation

• Main Body Positioning: Move the mobile toilet main body to the designated location and adjust its orientation to ensure reasonable placement of doors and windows (e.g., avoiding strong winds or direct sunlight).
• Fixation Methods:
  • Expansion Screw Fixation: Suitable for hard surfaces (such as concrete), drill holes and install screws to firmly connect the main body bottom to the ground.
  • Counterweight Block Fixation: Use concrete counterweight blocks to press down on the main body bottom on soft surfaces (such as soil or sand) to prevent shaking or tipping.

3. Core Component Installation

• Connection of Toilet Bowl and Fecal Storage Tank:
  • Align the toilet bowl's drainage outlet with the fecal storage tank's inlet, and use seals or silicone glue to fill gaps to ensure no leakage at the connection.
  • For dry toilets, fix the fecal storage tank's position to prevent movement; for water-flush toilets, connect the water tank and water pipes, and test the water pressure for stability.
• Water Supply/Drainage System Connection:
  • Water-flush toilets need to be connected to municipal water pipes or independent water tanks, and valves should be installed to control water flow.
  • The drainage system needs to be connected to a septic tank or designated drainage outlet, with a slope design that meets specifications (usually ≥2%) to prevent backflow.

4. Auxiliary Facility Assembly

• Door and Window Installation: Adjust the flexibility of door and window switches to ensure tight closure and prevent odor diffusion or rainwater infiltration.
• Accessory Installation:
  • Install handrails on both sides of the toilet bowl for easy gripping by users; add hooks to the walls for hanging items.
  • Lay anti-slip mats on the ground to reduce the risk of slipping, especially suitable for use by the elderly or children.
• Circuit Connection: Connect the power supply for lighting and exhaust fans, and test whether the power is on normally to ensure safe use at night.

5. Sealing and Debugging

• Sealing Treatment: Use silicone strips to seal gaps between the main body and the ground, and between doors and windows, to prevent odor leakage; check whether the connections of drainage pipes are tight.
• Functional Testing:
  • Flush Testing: Flush multiple times to observe whether the water flow is smooth, with no blockage or leakage.
  • Drainage Testing: Check whether the fecal storage tank can normally collect excrement and whether the drainage system has no backflow.
• Cleaning and Organization: Clean up installation residues, and place toilet paper, deodorants, and other items in the toilet to enhance the user experience.

6. Safety Inspection and Acceptance

• Structural Stability: Check whether the main frame and fixing screws are loose to ensure no risk of tilting or shaking.
• Signage Setting: Post emergency contact information, usage instructions, and hygiene standard reminders inside the toilet.
• Acceptance Criteria: Refer to the "Mobile Toilet Hygiene Standards" (GB/T 21239-2023) to confirm that hygiene, safety, and environmental protection indicators meet the standards before completing acceptance.

Notes: The installation of integrated box-type toilets is simpler, requiring only on-site hoisting, connection of water and electricity, and drainage pipes, which can be completed in 2-4 hours; such designs can be prioritized for remote scenic spots or temporary venues to reduce construction complexity.
