Longxi Color-Steel Mobile Toilet
The Longxi color-steel mobile toilet is a mobile sanitation facility designed with modular construction technology as its core, taking into account the natural conditions and environmental protection needs of the Gansu region. It features rapid installation, strong climate adaptability, and environmental protection and energy efficiency.
Manufacturing and Materials
The Longxi color-steel mobile toilet adopts modular construction technology, breaking down the toilet into independent functional units such as a frame structure, sanitation system, ventilation module, and sewage treatment components. Each unit is prefabricated in the factory and connected through standardized interfaces. The main covering material is aluminum-zinc alloy-coated steel plate, with an aluminum-zinc alloy layer applied through a hot-dip process on its surface, forming a dense protective film. This gives it weather-resistant properties, enabling it to withstand intense ultraviolet radiation and temperature variations. Internally, it is paired with light steel keels, which control transportation weight while ensuring overall strength, adapting to the variable natural conditions in Gansu.
Sewage Treatment and Environmental Protection
The sewage treatment system is a core technological aspect. Manufacturers in Gansu mainly employ three methods: biodegradable, physical separation, and chemical treatment. The biodegradable system decomposes organic matter by cultivating specific bacterial colonies; the physical separation system uses centrifugal force and filtration membranes to achieve solid-liquid separation; the chemical treatment system neutralizes harmful components with chemicals, suitable for regions with scarce water resources. Environmental protection performance is continuously improved. Water-saving devices have evolved from traditional direct-flush types to vacuum negative-pressure systems, reducing water consumption per flush to below 0.8 liters. The integration of solar power supply systems enables the mobile toilet to operate independently of the power grid, with the daily power generation of photovoltaic panels reaching up to 1.2 kilowatt-hours. In terms of the resource utilization of excreta, high-temperature composting technology can convert organic matter into soil conditioners.
Installation and Transportation
Regarding installation convenience, the frame material is aluminum-zinc alloy-coated steel plate, and the structural connection adopts a modular snap-fit and high-strength bolt combination system. All connection nodes undergo finite element simulation analysis to ensure that the displacement does not exceed 1/300 of the height under a 7-level wind load. The installation process does not require on-site welding operations. All prefabricated components adopt unified interface standards, and on-site assembly can achieve millimeter-level precision docking with the help of dedicated positioning fixtures. This reduces wet construction processes in traditional toilet construction by about 80%. On the construction site, only foundation leveling and embedded part fixation are required before starting the main body installation, and the entire installation cycle can be controlled within 6 working days. Transportation optimization is achieved through standardized container sizes. The outer packaging dimensions of each functional module are strictly controlled within the international standard container specifications of 2.4 meters wide × 2.4 meters high × 6 meters long. Transportation vehicles do not need to apply for special通行许可 (pass permits), and can travel unimpeded on the existing secondary road network in Gansu Province. All equipment inside the modules is integrated and debugged before leaving the factory, and only needs to be connected to water and electricity upon arrival at the site to operate, shortening the conversion time from equipment placement to operation to within 4 hours.
