Renovation of Mobile Public Toilets

The following methods can be referred to for renovating mobile public toilets:

I. Renovation with Waste Materials Using waste plastic barrels for renovation is a low-cost and environmentally friendly approach. First, install four flexible universal wheels at the corners of a wooden board. Use dozens of one-meter-long wooden strips to tightly clamp and fix them, ensuring structural stability. Cut the front of the wooden board with a cutting machine to create a suitably sized opening. Wrap the cut edges on both sides with wooden strips to form a door frame structure. Insert aluminum sheets one by one as partitions. Cover the top with the cut neck part of the barrel. Paint the inner wall wooden strips with white cement for beautification. Tightly clamp the sheets with wooden strips and assemble and make the door panel by fixing them with screws. Then, use male-female hinges and screws to attach the door panel to the door frame. Drill circular holes at the bottom of the barrel inside, install elbows and floor drains, and connect the plastic barrel with threaded reducers by punching holes. After punching holes at the bottom for installation, place it in the reserved opening on the top cover. Assemble and拼接 (here should be 'splice') three-way straight pipes and elbows into a shape resembling the Chinese character '日'. Install a valve switch in the middle, punch holes to connect to the water outlet, extend the outer bend downwards, install a valve switch and a three-way pipe, connect it to the barrel, insert screws to fix the clips, place the spray head, assemble and splice the toilet tank, and seal the edge gaps with adhesive. Connect the outdoor sewage pipe until it combines with the septic tank. Finally, install a connecting elbow water pipe and a bracket on the door and fix them with screws.

II. Renovation of Outdoor Public Toilets in Scenic Areas For outdoor public toilets in scenic areas, if they are 3 meters wide, 6 meters long, and cover an area of 18 square meters, metal insulated carved panels can be used as the exterior walls. This material offers good thermal insulation and decorative properties. Install a single glass door with colored aluminum, which is both aesthetically pleasing and practical. Install two squat toilets inside the women's restroom to meet usage demands.

III. Adhering to Design Principles Mobile toilets generally consist of a fecal sewage storage tank (or fecal sewage treatment device), floor, sanitary ware, walls, washing equipment, water tank, roof, and mobile device. When designing, principles such as mobility, cost-effectiveness, and durability; environmental protection and ecological benefits; and enhancing efficiency and promoting humanity should be followed. The overall structure should be lightweight, using lightweight and durable materials as much as possible while ensuring structural robustness. The design should also consider controlling the height and width of the toilet, and the mobile device should be fully considered for completeness and rationality to ensure the functionality and practicality of the mobile public toilet.
