Mobile Toilet Rainproof Design Specification

The mobile toilet rainproof design specification mainly includes aspects such as foundation site selection, main body waterproofing, drainage system, shell material, structural sealing, and waterproof testing, as detailed below:

Foundation Site Selection and Ground Treatment: The site should be at least 15 centimeters higher than the surrounding ground to prevent rainwater accumulation and submersion of the equipment base. The ground should be hardened, preferably with concrete pouring or moisture-resistant tiles, and the surface slope should be maintained at over 1% to ensure rapid drainage of rainwater from the equipment base, reducing the risk of water accumulation.

Main Body Waterproof Sealing of the Equipment: The sealing strips on the toilet doors and windows should be regularly inspected to ensure there are no gaps after closing, preventing rainwater infiltration. A rainproof eave should be installed on the top of the equipment, with an eave extension length of no less than 30 centimeters. During rainy seasons, additional drainage troughs can be installed to guide rainwater to the ground, avoiding direct impact on the main body of the equipment.

Drainage System Damp-Proof Design: The sewage pipes should be equipped with anti-backflow measures, and it is recommended to install a one-way valve when connecting to the municipal drainage system to prevent sewage backflow. When installing on the ground, a 5-centimeter-high water retaining platform should be reserved to prevent external rainwater from flowing back into the equipment and affecting its use.

Shell Structure and Material Selection: The shell should be made of high-strength composite materials, such as rust-resistant metals or special engineering plastics, with excellent wind pressure resistance. The roof design should be inclined to effectively divert rainwater, avoiding pressure or corrosion to the equipment caused by water accumulation.

Overall Structural Sealing: Sealing strips should be installed on all doors, windows, ventilation openings, etc., to effectively block wind, rain, and moisture from entering when closed. The width of door gaps should be controlled within a reasonable range to prevent water leakage due to excessively large gaps.

Waterproof Performance Testing: After equipment installation, a water storage test should be conducted for no less than 24 hours. Only when no obvious leakage is observed can the waterproof performance be deemed to meet the standard. This step is crucial for ensuring the equipment's effective rainproof performance in actual use.
