Assembly Process of Double-Occupancy Mobile Toilet

The assembly process of a double-occupancy mobile toilet typically includes six core steps: foundation preparation, main body hoisting, pipeline connection, internal debugging, external installation, and detail handling. The specific steps are as follows:

1. Foundation Preparation
Conduct a geological survey of the site, focusing on evaluating soil bearing capacity and drainage conditions. For double-unit structures, use concrete foundation slabs as support platforms to ensure a level foundation with adequate bearing capacity. Simultaneously, pre-embed sewage pipeline interfaces, with pipe diameters calculated based on the expected number of users (typically 30% larger than those of single-unit toilets), and reserve installation pits for septic tanks. For prefabricated toilets, pour concrete foundation piers in advance to provide stable support for subsequent main body installation.

2. Main Body Hoisting Stage
Transport prefabricated toilet units to the site using professional lifting equipment. Before hoisting, determine lifting point positions through load-bearing calculations to avoid structural deformation due to center-of-gravity shifts. During installation, ensure that the sealing strips between the base and foundation slab are properly positioned to prevent leakage during subsequent use. For prefabricated toilets, adjust the box angle using a level to ensure overall levelness meets specifications after installation.

3. Pipeline Connection Operations
The water supply and drainage system consists of two subsystems: water inlet and sewage discharge:

• Water Inlet Pipeline: Equip with dual independent valve controls for easy maintenance and inspection later.
• Sewage Discharge Pipeline: Use inclined tee connectors to merge the sewage pipes from the two toilet compartments into the main pipeline. The inclination angle must strictly adhere to specifications (typically 3%-5%) to prevent blockages. For microbial degradation toilets, connect the inlet and outlet pipelines of the biological treatment unit.

4. Internal Equipment Debugging
Focus on debugging sanitary fixtures and ventilation systems:

• Flush Valve: Adjust water pressure to water-saving standards (typically 0.1-0.15 MPa).
• Ventilation System: Double-unit structures usually share a main ventilation duct. Use an air volume detector to ensure balanced air pressure in the exhaust branches of each toilet compartment, preventing odor backflow.

5. External Auxiliary Facility Installation
This includes lighting systems, signage, etc.:

• Power supply lines must be protected with waterproof sleeves, and joints treated with professional sealant.
• Signage must comply with barrier-free design specifications, and reflective materials must be provided for nighttime use scenarios.

6. Detail Handling and Finalization
Thoroughly clean the interior and exterior of the toilet, check that all bolts and nuts are tightened, and focus on inspecting easily loosened parts such as door locks and hinges. For packaged toilets, test the sensitivity of the fecal bag automatic replacement device to ensure operational reliability.

Notes: The specific process may vary slightly depending on the toilet type (e.g., packaged, microbial degradation) or design differences. Before assembly, carefully read the product manual and have it performed by a professional team.
