Installation of Mobile Toilets in Gansu Square
The installation of mobile toilets in Gansu Square requires scientific design based on local environmental characteristics and usage needs, covering aspects such as materials, structure, sewage disposal, installation, and transportation. The specific technological features are as follows:
Material Selection: Gansu experiences a dry climate with little rainfall, large temperature differences between day and night, and cold winters. Therefore, materials must possess properties such as low-temperature resistance, corrosion resistance, and aging resistance. High-strength fiberglass is a commonly used material, known for its strong corrosion resistance and excellent low-temperature performance, with a service life of over 10 years. Some units are internally lined with insulation layers to cope with low temperatures. Color-coated steel plates, composed of color-coated steel sheets and core materials such as polyurethane or rock wool, offer strong compression and bending resistance. The surface coating slows down aging caused by the climate, and anti-corrosion treatment enhances durability in humid environments. Additionally, some cases use metal carved panels as exterior wall materials, which provide both fire resistance and insulation. Combinations of hot-dip galvanized materials, aluminum alloy toilet doors, PVC ceilings, and marble steps further enhance durability and aesthetics.
Structural Design: Modular design is adopted, allowing for rapid assembly and disassembly according to the square's scenario. The internal layout is flexible, with options for squatting positions, sit-down toilets, and barrier-free facilities. Color-coated steel components are prefabricated in the factory, including wall panels, roof panels, and internal partitions, and are assembled on-site using dedicated connectors. This reduces welding or concrete pouring processes, shortens the construction period, and lowers the complexity of on-site operations.
Sewage Disposal System: In response to Gansu's water scarcity, most toilets employ a water circulation system, where treated water can be reused. High-end models are equipped with automatic flushing and deodorization systems to ensure environmental hygiene. For areas without sewer pipes, environmentally friendly fecal tanks are used, which are regularly cleaned by dedicated personnel. Modern toilets often adopt biodegradation or physical filtration systems to reduce direct sewage discharge.
Installation and Transportation: The installation process is typically completed within 1-2 hours, offering high efficiency and convenience. Considering Gansu's complex terrain, special vehicles are required for transportation in mountainous scenic areas, while urban installations must pay attention to traffic and pedestrian safety. Most manufacturers provide comprehensive transportation and installation services. Foundation treatment employs concrete foundations or adjustable steel supports to adapt to different ground conditions.
