Construction Site Portable Toilet

Portable toilets for construction sites are designed to meet the temporary and phased toilet needs of construction sites. They are movable, combinable, and easy to transport. Their production methods, structural types, and functional characteristics are as follows:

I. Production Methods

1. Handmade Retrofitting Type: Utilize discarded water storage tanks and pallets for production. The specific steps are as follows: Install universal wheels at the four corners of the bottom of the pallet and place the recycled water storage tank on it. Use an angle grinder to cut along the marked lines on the top to form an open tank body. Stack two open tank bodies upside down and fix them with self-tapping screws. Cut a rectangular opening as the doorway and drill a hole in the internal floor to insert an elbow and a water pipe, and then seal it. Install facilities such as toilets, faucets, and washbasins, and finally make a door with wooden boards and hinges. This method has low costs and is suitable for small-scale temporary use.
2. Factory Customization Type: Customize the number of squatting positions according to the proportion of workers on the construction site. For example, a construction site in Zhejiang customized a toilet with 7 male squatting positions and 1 female squatting position due to a large number of male workers, and it was completed in an urgent 4 days. Factory customization can flexibly adjust the structure, materials, and functions to meet personalized needs.
3. Folding Transportation Type: Some companies have developed folding toilets. When folded, they are only 90 centimeters high and can be transported by pickup trucks or box trucks. They can be used immediately after being unfolded, making them suitable for construction sites that require frequent movement.

II. Structural Composition and Classification

1. Basic Structure: It includes a fecal sewage storage tank (or disposal device), floor slabs, sanitary ware, walls, washing equipment, water tanks, roofs, and moving devices.
2. Structural Form Classification:
   • Single-unit Structure: An independent unit suitable for sites with limited space.
   • Composite Structure: Composed of multiple units, it can expand capacity to meet the needs of large-scale construction sites.
3. Moving Method Classification:
   • Lifting/Handling Type: Requires lifting equipment or manual handling and is suitable for short-distance movement.
   • Powered/Trailer Type: Equipped with a power device or can be towed, suitable for long-distance transportation.
4. Sewage Treatment Method Classification:
   • Flush and Non-flush Suction Type: Rely on water sources for flushing or regularly suck out feces.
   • Recirculating Flush Type: Recycle water resources through a filtration system to reduce water consumption.
   • Dry Packaging Type: Use biodegradable bags to collect feces, requiring no water source and suitable for water-scarce areas.

Portable toilets effectively solve the toilet problems on construction sites through modular design and diverse functions while taking into account environmental protection and convenience.
