On-site Made Mobile Toilet

The on-site made mobile toilet can be constructed using materials such as water storage tanks and pallets. Its core structure includes the modification of the water storage tank, the installation of mobile devices, and the configuration of sanitary facilities, featuring mobility and ease of assembly.

I. Production Materials and Basic Structure

The core materials for on-site mobile toilet production are water storage tanks and pallets. Water storage tanks are typically made of plastic or metal and must possess a certain load-bearing capacity and sealing properties. During production, universal wheels are fixed to the bottom of the pallet to form a mobile chassis structure. The water storage tank requires cutting and modification: a single tank is horizontally cut into upper and lower parts, with the upper part serving as a top-opening sewage storage tank and the lower part remaining intact as a base; or two tanks are stacked and fixed with welding or bolts to enhance stability. A doorway is cut on the side of the tank, sized to accommodate human passage, with edges polished smooth to avoid cuts.

II. Sanitary Facility Installation and Function Realization

1. Excretion System: The toilet should be lightweight, such as plastic or foldable designs, directly fixed to the tank opening with a sealed connection to the sewage storage tank. If a septic tank design is adopted, a partition should be installed inside the tank to separate solids and liquids, reducing odors.
2. Water Supply System: A water tank can be installed on the top or side of the toilet, connected via pipes to a faucet and sink. The faucet should be water-saving, and a drainpipe should be installed beneath the sink to direct wastewater into a separate water storage tank or directly discharge it (complying with environmental requirements).
3. Doors, Windows, and Ventilation: The door can be made of lightweight materials (such as PVC or aluminum alloy), fixed to the tank doorway with hinges, and equipped with a lock for privacy. Ventilation requires openings on the roof or walls, with exhaust fans or natural ventilation devices installed to prevent stale indoor air.

III. Mobility and Stability Optimization

Universal wheels should be industrial-grade models with strong load-bearing capacity, with at least four evenly distributed at the corners of the pallet. If the toilet is large, additional wheels or braking fixtures can be added to prevent sliding during use. The connection between the tank and the pallet should be reinforced with bolts or welding to prevent detachment during transportation or use. The roof can be made of lightweight materials (such as color steel plates or sunshine boards), fixed to the top of the tank with brackets to provide rain protection and reduce overall weight.

IV. Classification and Advantages

According to structural form, on-site made mobile toilets can be divided into single-unit types (modified from a single tank) and combined types (assembled from multiple tanks); by mobility method, they can be classified as towed types (requiring vehicle traction) and self-propelled types (with power devices). Their core advantages lie in flexibility—they can be quickly assembled or disassembled according to site requirements, environmental friendliness—reducing pollution through sealed designs, and cost-effectiveness—lowering costs by utilizing used water storage tanks, making them suitable for temporary events, post-disaster reconstruction, and other scenarios.
