Installation of Color Steel Plate Mobile Toilets
The installation of color steel plate mobile toilets requires systematic planning, covering environmental assessment, main structure assembly, supporting system integration, and precision inspection. The specific process is as follows:
1. Pre-installation Preparation
Environmental assessment should consider geological and climatic conditions. For example, in Qinghai, the coefficient of thermal expansion and contraction of color steel plates needs to be calculated to prevent structural deformation. In Xinjiang's sandy soil areas, a combination of concrete foundations and ground anchors is used, while in permafrost zones, the foundation depth needs to be increased to reduce earthwork excavation. Foundation treatment should be adjusted according to the geology: sandy soil areas require concrete foundation reinforcement, and permafrost zones require deeper foundations to ensure stability.
2. Main Structure Installation
Modular assembly uses high-strength galvanized bolts and sealing gaskets, strictly adhering to torque standards to avoid deformation or sealing failure of the color steel plates. Electrical and water supply/drainage pipes use quick-connect interfaces with anti-leakage and anti-freeze designs. Panel splicing employs hidden fastening technology, with wall panels connected via internal slots and external seams sealed with waterproof strips. The roof is designed with a slight curve to enhance load-bearing capacity and direct rain and snow away, reducing the load.
3. Supporting System Installation
Insulation layer composite uses a multi-layer structure, with an outer layer of color steel corrugated plates and an inner layer filled with polyurethane foam. The foam must be poured in a constant temperature and humidity environment to ensure uniform foaming and prevent cold bridges. Sewage systems are adapted to local conditions: some areas in Qinghai use negative pressure collection systems, where waste is transported to collection containers via micro vacuum pumps, requiring maintenance of sealing and negative pressure values. Xinjiang combines biological degradation with physical separation, where solids and liquids are separated, solids are decomposed with bacterial agents, and liquids are filtered for non-potable use. Water-saving technology utilizes pressure differential principles to reduce water consumption. Induction flow limiters on sinks limit single-use water to ≤0.5 liters, and some models recycle sink wastewater for secondary flushing, achieving a 70% water-saving rate. Energy systems integrate photovoltaic power generation, with solar panels installed to fit the roof's curved surface. Energy storage uses low-temperature lithium battery packs, with intelligent power supply strategies to adapt to unstable power supply in high-altitude areas.
4. Intelligent Monitoring and Precision Inspection
After installation, a multi-parameter sensor network is deployed to monitor odor concentration, liquid levels, temperature, and humidity in real-time, with data networked via IoT modules to optimize maintenance cycles. 3D laser scanning inspection compares the design model, focusing on checking verticality, joint flatness, and equipment positioning accuracy. In high-altitude areas, specialized airtightness testing is required, using micro differential pressure gauges to measure sealing at key nodes.
5. Installation Costs
The installation cost for a standard color steel plate mobile toilet is approximately 500-2000 yuan, including foundation work. In remote areas, transportation costs increase by 500-2000 yuan, and complex installations (such as high-altitude hoisting) require additional labor cost assessments. Long-term operating costs include cleaning services (30-50 yuan per session) and consumables (200-500 yuan annually), with total costs typically ranging from 500-2500 yuan.
