Mobile Installation Case of Public Toilets

Typical cases and technical features of mobile installation of public toilets are as follows:

I. Mobile Toilet Installation Case in the Scenic Area along the Yellow River in Lanzhou

In 2023, the scenic area along the Yellow River in Lanzhou introduced and put into use multiple mobile toilets to enhance the toilet-using experience for tourists. In this case, the location selection of mobile toilets took into account both the tourist flow in the scenic area and the harmony with the landscape, giving priority to tourist-concentrated areas and along the footpaths. The installation process did not damage the original ground structure. Instead, it only involved leveling the site and using special anti-slip mats for fixation. Some models utilized their built-in pulley systems for rapid positioning. The bottom of these toilets adopted high-strength load-bearing bases to distribute pressure to the ground, preventing damage to lawns or hard pavements and eliminating the need for secondary site restoration after removal.

The design of the water and electricity systems demonstrated intelligence and environmental friendliness: The water supply pipes used quick-disconnect fittings for rapid connection to the existing water supply network in the scenic area; the sewage system was equipped with detachable sewage storage tanks, which were regularly pumped and treated by special vehicles, eliminating the need for laying underground sewage pipes and reducing interference with the scenic area's ecology. In addition, the toilets were internally equipped with automatic ventilation systems that continuously expelled odors through negative pressure principles and were powered by solar panels to reduce energy consumption. Some high-end models also featured smart displays that showed real-time usage status and remaining capacity, along with emergency call buttons to enhance safety.

II. Technical Advantages of Modern Mobile Toilets

1. Material and Structure: The main body is made of lightweight, high-strength polyethylene or color-coated steel plates, balancing durability and portability. The modular design allows installation to be as easy as 'building blocks', with a single toilet being assembled within a few hours, significantly shortening the construction period.
2. Mobility and Flexibility: Some models incorporate pulley systems, requiring only 4-5 people to move and adjust their positions, meeting the needs of temporary events, disaster relief, and other scenarios.
3. Eco-Friendliness: The load-bearing base design avoids concrete hardening of the ground, protecting vegetation; detachable sewage storage tanks and quick-disconnect water and electricity interfaces reduce dependence on infrastructure and lower environmental impact.
4. Intelligent Functions: Technologies such as solar power supply, automatic odor removal, and smart monitoring enhance the user experience, while emergency call devices ensure the safety of special groups.

These cases demonstrate that through technological innovation, mobile toilets have achieved the goals of 'rapid deployment, eco-friendliness, and intelligent management', providing efficient solutions for the construction of sanitation facilities in public spaces.
