Datong Outdoor Mobile Toilet Installation

The installation of outdoor mobile toilets in Datong should follow the following key steps and points:

I. Construction Preparation Phase

1. Drawing Review and Technical Disclosure: Organize the design, supervision, and construction units to jointly review the structural, water supply and drainage, and electrical drawings, focusing on verifying the compatibility of equipment dimensions, pipeline routes with the scenic area's infrastructure. The project technical leader must clarify process standards, safety requirements, and key process control points to the construction team.
2. Surveying and Material Preparation: Use a total station for precise layout and set control stakes. Purchase main materials (such as SMC fiberglass wall panels, aluminum alloy frames), equipment (vacuum suction toilets, biodegradation treatment equipment), and auxiliary materials (PE water supply pipes, UPVC drainage pipes) that meet environmental standards, ensuring quality compliance.
3. Site Preparation and Temporary Facilities: Clear weeds and stones from the site, compact the soil, and set drainage slopes; construct material storage areas, tool rooms, and temporary office areas, and set up drainage ditches and warning signs.

II. Main Construction Phase

1. Foundation Pit and Foundation Construction: Excavate the foundation pit mechanically, with a width 300mm larger than the designed foundation and a depth reaching 500mm below the frost line; manually clean the bottom and pour the foundation, embedding pipelines to ensure stability.
2. Modular Assembly: Adopt a 'factory prefabrication + on-site hoisting' model, where the main structure is welded and painted in the workshop before being transported to the site for assembly. The cabin bottom is equipped with load-bearing legs to adapt to uneven ground and is fitted with a typhoon-resistant reinforcement system.

III. Functional Facility Installation

1. Sanitary Ware and Water-Electricity Systems: Install squat toilets, washbasins, and other sanitary ware, ensuring they are securely fixed; connect water supply and drainage pipes and electrical circuits, and test water supply, drainage, and lighting functions.
2. Environmental Protection Treatment Units: Configure biodegradation or chemical decomposition modules according to needs to treat excreta and reduce odors.

IV. Commissioning and Acceptance Phase

1. Equipment Commissioning and Trial Operation: Check the equipment's operating status, troubleshoot issues such as water leakage and electric leakage, and ensure system stability.
2. Sub-item Acceptance and Data Handover: Conduct sub-item acceptance according to standards and hand over completion data after passing the inspection.

V. Handover and Maintenance

1. Usage Training: Provide operational training to management personnel, including cleaning, equipment inspection, and emergency handling.
2. Regular Maintenance: Develop a cleaning plan, replenish consumables (such as toilet paper, hand soap), regularly inspect equipment, and remove waste to ensure long-term usability.

By following these steps, the installation of outdoor mobile toilets can be systematically completed, balancing functionality and environmental protection to meet the climatic and usage needs of the Datong region.
