Installation of Mobile Toilets in Nanchang City

The installation of mobile toilets in Nanchang City should follow a scientific process, covering multiple stages such as preliminary preparation, transportation and unloading, installation and commissioning, signage setup, and follow-up services to ensure stable operation and safety of the equipment.

I. Preliminary Preparation

1. Site Selection: Prioritize flat terrain with convenient drainage and away from water source pollution to ensure harmony with the surrounding environment. For example, installations in scenic areas should avoid areas with heavy tourist traffic and consider the coverage of nighttime lighting.
2. Site Condition Confirmation: Check the firmness of the ground; soft ground requires laying wooden planks or gravel. Remove obstacles to ensure unobstructed access for transport vehicles and equipment.
3. Approval Procedures: For installations in public places or scenic areas, apply for temporary facility permits in advance to avoid being ordered to dismantle due to violations.

II. Transportation and Unloading

1. Transportation Method: Use dedicated vehicles to secure the equipment and prevent damage from shaking during transit; add shock-absorbing padding for long-distance transportation.
2. Unloading Specifications: Confirm the ground's load-bearing capacity and use forklifts or manual labor to slowly unload the equipment, avoiding collisions with the container body; the tilt angle should not exceed 15° to prevent displacement of internal components.

III. Installation and Commissioning

1. Foundation Fixing: Use expansion screws or counterweights to fix the equipment, ensuring the wind resistance level meets local meteorological standards (e.g., the average annual wind speed in Nanchang should meet the requirement for wind resistance of level 5).
2. Drainage System: Connect the drainage pipe to the designated sewer or collection tank, reserving 20% of the tank's capacity to prevent overflow; for eco-friendly toilets, check the seal of the fecal tank.
3. Water and Electricity Testing: Connect to a temporary power source or generator to test lighting and flushing systems (recommended flush volume of 3-6L per use); the fecal tank capacity should meet the maximum daily usage demand.
4. Detail Inspection: Confirm that door locks and ventilation systems (with an air exchange rate of ≥8 times per hour) are functioning properly, and provide sufficient supplies such as toilet paper and hand sanitizer.

IV. Signage Installation

1. Position Specifications: Set up signs within 3-5 meters of the entrance, at a height of 1.5-1.8 meters; additional auxiliary signs are required for entrances from multiple directions.
2. Material and Style: Use waterproof and sun-resistant PVC boards or acrylic boards, with a primary color scheme of blue/green; use bold or rounded fonts with a font size of ≥10cm to ensure readability from a distance.
3. Classification Design: Functional signs should indicate toilet types (e.g., "Men/Women/Accessible"), directional signs should guide the way, and reminder signs should include civilized messages such as "Save Water" and "Flush After Use."

V. Follow-up Services and Rental Provider Selection

1. Daily Maintenance: Clean the toilets daily and replenish supplies during the rental period; the collection tank should be cleaned every 2-3 days to prevent odor diffusion.
2. Emergency Response: Maintain a 3-day supply of spare toilet paper and disinfectant; the rental provider should respond to equipment failures within 2 hours for repairs.
3. Rental Provider Screening: Prioritize providers with municipal engineering qualifications, a wide range of available products (e.g., squat-type, sit-type, high-end smart-type), and fast service response times.
