Haixi Mobile Toilet Design
The design of mobile toilets in Haixi covers key aspects such as structural material selection, layout, environmental protection, and adaptability.
In terms of structural frame material selection, Haixi color-steel mobile toilets mostly use high-strength cold-formed thin-walled steel. This material, formed through cold working, can provide sufficient structural support while maintaining a relatively low self-weight, meeting the requirements for frequent movement and installation. The color-coated steel sheets covering the frame surface are an important component. They are composite materials formed by continuous roll-coating and baking processes on a metal substrate, offering corrosion resistance, weather resistance, and certain thermal insulation properties. Qinghai Shiquan Color Steel Factory adjusts the coating formula and thickness according to the environmental characteristics of the plateau region, such as strong ultraviolet radiation and large temperature differences.
For connection methods, bolt assembly is commonly used at the connection nodes of the frame instead of welding. This design fully considers the convenience of disassembly and reassembly while ensuring the structural integrity.
In terms of internal layout, the mobile public toilet is designed with a layout of four squatting positions plus one management room. The configuration is very comprehensive, including ceramic squatting pans, flush tanks, exhaust fans, ceiling lights, and urinals, which can meet people's basic usage needs.
Environmental protection is a major highlight of the mobile toilet design in Haixi. It adopts standardized and modular design, with most components pre-cut and formed in the factory and assembled on-site, significantly reducing the construction waste generated in traditional civil engineering. Its water treatment system integrates multi-stage combination technologies of physical sedimentation, biological degradation, and chemical treatment. The treated effluent can be used for flushing or green irrigation, reducing the pressure on municipal pipe networks and the consumption of freshwater resources. For excrement disposal, replaceable sewage storage tanks are used in combination with subsequent professional collection and centralized treatment, avoiding non-point source pollution caused by indiscriminate discharge. Moreover, the main structural steel and color-coated steel sheets are highly recyclable materials. After the product reaches the end of its service life, most of the materials can enter the recycling cycle, reducing the final landfill volume of construction waste.
In addition, for the low-temperature environment of the plateau, the mobile toilets in Haixi have also undergone adaptive design. By increasing the thickness of the insulation layer and optimizing the tank structure to increase the effective volume for microbial reactions, the activity of the biological treatment unit can be maintained at low temperatures, ensuring stable treatment effects in different seasons.
