Construction of Mobile Toilets in Dingxi Scenic Area

The construction of mobile toilets in Dingxi scenic area requires the integration of modular design, foundation adaptation, system installation, and functional configuration. The specific process is as follows:

1. Modular Manufacturing and Transportation
The main structure of the mobile toilet is standardized and produced in a factory, including components such as walls, roofs, sewage, and ventilation pipes. Modular design enables 'production on demand and immediate use'. During transportation, independent units are transported to the scenic area by road and quickly placed on pre-leveled foundations using lifting equipment. This approach shortens the on-site construction period and reduces interference with the scenic environment.

2. Foundation Adaptation and Fixation
Dingxi is located on the Loess Plateau, where the foundation has collapsible characteristics, necessitating tailored adaptation solutions:

• Sand and Gravel Compaction: Suitable for geologically stable areas, improving load-bearing capacity by layering and compacting sand and gravel.
• Concrete Piers: Pouring concrete piers on soft foundations to distribute equipment weight.
• Screw Piles: Mechanically screwed into the ground to form stable supports, suitable for mountainous or complex terrains.
  Equipment is fixed using anchor bolts connected to concrete foundations. In mountainous scenic areas, additional wind-resistant guy wires are installed to prevent structural displacement caused by strong winds.

3. Power Supply and Sewage System Installation

• Power Supply System: Priority is given to solar-assisted power supply, paired with batteries to meet electricity needs at night or on cloudy/rainy days.
• Water Supply: Replenished through small water storage tanks or directly connected to the existing water supply network in the scenic area.
• Sewage Treatment:
  • Sealed Septic Units: Suitable for areas without a sewage network, requiring periodic pumping and treatment.
  • Connection to Sewage Treatment Stations: Directly connected to centralized treatment systems when the scenic area has an existing network.
  • Biological Treatment Type: Microbial agents are added to accelerate the decomposition of solid waste, reducing odors and pollution.

4. Functional Module Configuration
Flexibly adjusted according to tourist flow and ecological needs in the scenic area:

• High Tourist Flow Areas: Increase the number of units or use multi-pit combination modules to enhance service capacity.
• Ecologically Sensitive Areas: Select eco-friendly modules equipped with high-level sewage treatment systems to reduce environmental load.

5. Installation, Debugging, and Acceptance
The enterprise provides installation drawings and basic construction guidance, with a production cycle typically ranging from 7 to 10 working days. Support is provided for adding solar panels, insulation layers, or custom ethnic pattern exterior finishes as needed. Equipment is delivered directly using flatbed trucks and lifting equipment, with free basic leveling and grounding detection services provided to ensure stable operation of the equipment.
