Installation of Single Mobile Toilet in Dingxi

The installation of a single mobile toilet in Dingxi features modular construction and rapid deployment, typically completed within 3 hours without the need for heavy machinery assistance.

Modular Construction and Transportation

The functional units of the mobile toilet are designed with standardized interfaces for quick assembly and disassembly. During transportation, the overall dimensions strictly adhere to road transportation regulations, allowing for rapid deployment at the installation site using hydraulic devices, thereby reducing on-site construction time.

Foundation Adaptation Solutions

Given the characteristics of the collapsible loess foundation in Dingxi's Loess Plateau, multiple foundation adaptation solutions are provided:

• Sand and Gravel Compaction: Suitable for areas with good geological conditions and high bearing capacity, enhancing foundation stability through layered compaction of sand and gravel.
• Concrete Piers: In areas with soft geology or insufficient bearing capacity, concrete piers are poured as support foundations to enhance overall stability.
• Screw Piles: Ideal for mountainous or complex terrain areas, screw piles are directly fixed underground, reducing the requirement for ground levelness.

Connection and Fixation Methods

The connection between the toilet bottom and the ground must incorporate anti-displacement design. In mountainous scenic areas, additional wind-resistant cables are installed to enhance wind resistance. Equipment is typically fixed using anchor bolts connected to concrete foundations to ensure long-term stability.

Functional Unit Assembly

Modules such as toilet compartments, ventilation systems, and sewage systems are assembled according to design requirements. The sewage system requires higher sealing performance than in humid areas, necessitating the use of special sealing materials to prevent sand intrusion and avoid blockages or leaks.

Supporting System Commissioning

After completing water and electricity connections, supporting equipment such as water-saving flushing systems, greywater recycling devices, and solar power systems must be commissioned. During commissioning, the smooth operation of each system is checked to ensure compliance with water-saving, energy-saving, and environmental protection standards.

Acceptance Criteria

Upon completion of installation, acceptance must be conducted according to dual standards:

• National Standards: Compliance with GB/T 18045-2021 'General Technical Conditions for Mobile Public Toilets'.
• Local Standards: Meeting the filing requirements of Gansu Province's 'Technical Guidelines for Rural Human Settlements Improvement' to ensure applicability and compliance.

Through the above process, mobile toilets in Dingxi can achieve efficient, safe, and environmentally friendly installation and use.
