Box-type Mobile Toilet Installation

The installation of box-type mobile toilets requires standardized operations in stages, focusing on preliminary preparations, on-site installation, and special design adaptations. The specific steps are as follows:

I. Pre-installation Preparations

1. Site Survey and Planning
   Determine the installation location in advance, ensuring the ground is flat and solid, away from main construction roads, pollution sources, and foundation pit edges (recommended distance ≥ 1.5 meters) to avoid the impact of construction vibrations or settlement on toilet stability. If for temporary use, reserve space for lifting operations.

2. Material and Equipment Verification
   After receiving the equipment, check the integrity of the box (e.g., no deformation or cracks) and the completeness of accessories (including door locks, flush valves, sewage pipes, sealing tapes, etc.). If any damage or missing parts are found, contact the supplier immediately for replacement to avoid installation interruptions.

3. Foundation Treatment
   Select the foundation type based on the toilet type (single or connected):

• Single toilet: After clearing debris from the ground, lay a 10-15 cm thick gravel layer or pour a C20 concrete foundation to ensure a load-bearing capacity ≥ 200 kg/㎡ (standard for single-person toilets).
• Connected toilet: Expand the foundation area and embed anchor bolts or weld connecting pieces to enhance overall stability.

II. On-site Installation Steps

1. Box Lifting and Positioning
   Use a forklift or crane to lift the toilet body smoothly to the designated location and adjust its levelness with a spirit level to prevent tilting, which could cause door lock jamming or poor drainage. Unified command is required during multi-person operations to prevent collisions.

2. Drainage System Connection
   Connect the sewage pipe to the construction site's drainage network or temporary collection pit, wrapping sealing tape or applying cement at the joint to prevent leakage. If there is a risk of backflow in the drainage pipe, install an anti-backflow valve to ensure unidirectional sewage flow.

3. Flush System Debugging
   After connecting the water source (tap water or a dedicated water tank), test the flush function:

• Check if the flush valve opens and closes flexibly and if the water volume is appropriate (usually completing flushing in 3-5 seconds).
• Observe if the drainage pipe is unobstructed to avoid water accumulation or blockage.

4. Internal and External Facility Inspection

• Internal: Confirm that the sink, hooks, toilet paper holder, etc., are firmly fixed without looseness; test if electrical equipment such as lights and exhaust fans are working properly.
• External: Check the sealing of the box joints to ensure no air or water leakage, preventing odor diffusion or rainwater infiltration.

III. Special Design Adaptations for Container Toilets

If it is a container-type toilet, note the following:

• Structural Connection: Use high-strength bolts to fix the steel structure frame, avoiding welding operations for easy disassembly and reuse in the future.
• Thermal Insulation Treatment: Use foam color steel sandwich panels or rock wool sandwich panels for wall panels to reduce condensation problems caused by temperature differences.
• Equipment Room Layout: Ensure that the sewage treatment unit (such as septic tanks and filtration devices) is isolated from the toilet compartment to avoid cross-contamination of odors.

IV. Usage and Maintenance Recommendations

After installation, regularly clean and disinfect the toilet and replenish consumables; inspect the electrical circuit, valves, and flush system monthly, and repair any abnormal noises or malfunctions promptly; set up warning signs around the toilet and keep it away from flammable and explosive materials to ensure electrical safety.
