Installation of Color-Steel Mobile Toilets in Tibet
The installation of color-steel mobile toilets in Tibet achieves adaptability to the unique high-altitude environment through material, structural, construction, and system design. The specific features are as follows:
1. Materials and Structure: Cold-Resistant, UV-Resistant, and Modular for Rapid Assembly
The toilet body is made of rock wool sandwich color-steel plates, which are cold-resistant (below -40℃), UV-resistant, and have a low thermal conductivity coefficient. The interior is filled with polyurethane or rock wool insulation layers, forming a closed air layer that effectively maintains stable internal temperatures. Structurally, it adopts a modular design, consisting of an anti-corrosion galvanized steel frame, an integrated fecal treatment system, and a solar power supply unit. Each unit is prefabricated in the factory and assembled on-site using standardized interfaces, reducing on-site construction time. For example, Qinghai Shiquan Color-Steel Factory customizes reinforced foundation connection components based on geological data to enhance overall stability.
2. Foundation Treatment: Adapting to Permafrost with Minimal Environmental Impact
For the high-altitude permafrost layer, the foundation employs an adjustable steel frame or shallow-buried insulation layer design to avoid disturbing the permafrost structure. During installation, the main body is assembled first, followed by the use of a portable geological radar to detect underground conditions. The height of the anchor bolts is adjusted, and anti-slip access panels are laid to ensure the facility is stable without damaging surface vegetation. The entire process can be completed within 72 hours and generates no construction waste, meeting high-altitude ecological protection requirements.
3. Sewage Disposal and Energy: Biodegradation + Off-Grid Power Supply
Fecal treatment relies on a dual mechanism of biodegradation and physical separation: microbial agents decompose organic matter in an insulated fecal storage tank, with the treatment cycle extended by 40%-60% compared to normal-temperature regions. The treated liquid is disinfected and discharged to meet standards, while the residue is transported to low-altitude areas for further processing. Energy supply adopts an off-grid model, with solar panels paired with lithium iron phosphate battery packs prioritizing power for lighting and ventilation systems. In rainy weather, basic operation can be maintained for 168 hours, reducing reliance on traditional energy sources.
4. Ecological Protection and Construction Standards: Minimizing Intervention
The installation process does not require hardening the ground, preserving the integrity of meadow root systems. Workers adhere to high-altitude construction safety regulations, controlling continuous work hours and providing oxygen supply equipment to reduce health risks. Fecal treatment meets high-altitude water discharge standards, preventing environmental pollution.
5. Maintenance and Sustainability: Relocatable and Recyclable
Daily maintenance includes cleaning, checking sealant strips, and inspecting ventilation system performance. In high-wind environments, connection components need reinforcement, and UV protection requires regular replacement of surface coatings. The facility can be disassembled and relocated as a whole, with materials recyclable to avoid construction waste and achieve resource recycling.
