Qinghai Mobile Toilet Installation Project
The Qinghai mobile toilet installation project requires comprehensive consideration of environmental adaptability, technological integration, and construction specifications. The following are the key points:
1. Environmental Adaptability Design The characteristics of high altitude, strong ultraviolet rays, and large temperature differences between day and night in Qinghai require an assessment of ground bearing capacity, permafrost depth, and wind variations before installation. For color-coated steel materials, plates with anti-ultraviolet, low-temperature resistance, and a thickness of ≥0.4 millimeters should be selected, and the coefficient of thermal expansion and contraction should be accurately calculated to avoid structural deformation. For foundation treatment, excavate foundation pits that exceed the permafrost line, pour concrete, and embed fixed components. For sandy soil, expand the foundation area or add ground anchor devices.
2. Modularization and Connection Technology The main structure adopts modular assembly, with high-strength galvanized bolts and sealing gaskets used at connection points to balance rigidity and flexibility. Electrical circuits and water supply and drainage pipes use quick-plug interfaces with anti-leakage and anti-freeze cracking designs to meet installation requirements in complex terrains.
3. Insulation and Sewage Disposal Systems The walls adopt a multi-layer composite structure, with a color-coated steel corrugated plate as the outer layer and polyurethane foam filled in the inner layer. The pouring process requires constant temperature and humidity to ensure uniform foaming. For the sewage disposal system, in areas without municipal sewage networks, negative pressure collection technology is mostly used, where a micro vacuum pump transports waste to a collection container. The pipes have a small diameter and flexible layout.
4. Energy and Intelligent Integration The photovoltaic power generation system is installed by fitting custom brackets to the roof. The energy storage device selects low-temperature lithium battery packs and is equipped with an intelligent charge-discharge controller. The intelligent monitoring network deploys sensors for odor concentration, liquid level, temperature, and humidity, etc., and collects data in real-time through the Internet of Things to optimize maintenance cycles.
5. Construction and Acceptance Specifications After installation, three-dimensional laser scanning inspection is required, focusing on checking verticality deviation, joint flatness, and equipment positioning accuracy. Special inspections for air tightness are needed due to high-altitude air pressure changes. The ventilation system uses adjustable ventilators at the top and insect-proof net air inlets to form a low-convection cycle. For internal facilities, materials that are corrosion-resistant and easy to clean are selected. The electrical circuits are laid separately and equipped with leakage protection devices.
6. Age-Friendly and Convenience Facilities Referring to the toilet improvement initiative in Haibei Tibetan Autonomous Prefecture, the project can add handrails, barrier-free toilet stalls, third toilets, and母婴 facilities (maternity and child facilities). It promotes the layout of prefabricated and mobile toilets to improve usability.
