Baiyin Mobile Board House Toilet
The Baiyin mobile board house toilet is a temporary sanitation facility that uses galvanized aluminum-zinc steel plates as its main material, featuring a modular structure, mobility, a well-developed sewage system, and low maintenance requirements.
Material Characteristics: The main body is made of galvanized aluminum-zinc steel plates, composed of 55% aluminum, 43.4% zinc, and 1.6% silicon fused at high temperatures. A dense oxide layer naturally forms on the surface, creating a dual-phase protection mechanism of 'aluminum-zinc-aluminum'. In atmospheres containing sulfides, its weather resistance is significantly better than that of ordinary steel, effectively resisting corrosion and extending service life.
Structural Design: It adopts a modular box structure, with polyurethane foam material filled inside the wall panels, having a closed-cell rate exceeding 90%. This not only blocks heat conduction but also prevents water vapor condensation, adapting to different climatic conditions. The floor panel features a double-layer design with anti-slip aluminum plates and anti-leakage trays, with a maintenance gap reserved in the middle for easy upkeep and prevention of sewage leakage.
Mobility Implementation: There are two types: integral and assembled. The integral type is transported as a whole using lifting equipment by welding standard container corner fittings at the bottom of the box. The assembled type involves disassembling the panels for transportation and reassembling them on-site. Both methods require addressing the connection of the sewage system, typically using flexible reinforced corrugated pipes as temporary connecting pipes, with sealing rings and quick clamps at the interfaces to ensure tightness.
Sewage System Functionality: For freeze protection, in cold climates, the pipes are covered with electric tracing tapes and insulation materials, and the control system automatically adjusts the heating power through temperature sensors. For odor control, in addition to traditional exhaust pipes, micro negative pressure devices can be installed. Waste treatment can be connected to prefabricated septic tanks or municipal sewage networks, with some models integrating biodegradation devices to reduce environmental pollution.
Maintenance Management Points: Daily cleaning requires rinsing the surface of the galvanized aluminum-zinc steel plates with a neutral detergent. Structural inspections should focus on whether fasteners are loose, and after frequent movement, bolts should be retightened according to the manufacturer's torque parameters. The pipe system should be regularly inspected for aging of seals, and flexible connecting pipes are recommended to be replaced every two years to reduce the risk of failure.
Application Value: In large outdoor events, the deployment density can be dynamically adjusted according to the flow of people. In temporary workplaces such as construction sites and exploration camps, it can quickly provide infrastructure that meets sanitation standards. During underground pipeline maintenance, it can serve as a temporary alternative to maintain public service functions. Its material characteristics and modular design reduce the maintenance requirements throughout its life cycle, resulting in a long service life and cost-effectiveness for single use.
