Mobile Toilet Waterproof and Windproof Test

The waterproof and windproof tests of mobile toilets need to be carried out through process verification, structural testing, and real-world environmental simulations to ensure their stability and safety in severe weather conditions.

Waterproof Test

The waterproof performance of mobile toilets is mainly verified through rainfall simulation and long-term field tests.
1. Process Verification: Mobile toilets using an integrated molding process have been tested to withstand a heavy rainfall rate of 100mm/h (equivalent to an extremely heavy rainstorm level) without leakage. This process reduces the risk of water seepage at seams through a seamless structure, enhancing overall waterproofing.
2. Long-term Field Tests: After three consecutive days of rainfall, the mobile toilets from Anhui Zhisheng Environmental Protection Engineering Co., Ltd. showed no signs of leakage on interior walls or floors. This data indicates that their waterproof design can handle continuously humid environments and meet daily usage requirements.
3. Key Design Elements: Waterproof performance depends on material selection and structural sealing. For example, a sloped roof design accelerates rainwater runoff, while the connections between walls and floors are treated with waterproof strips or sealants to further reduce the probability of water seepage.

Windproof Test

Windproof performance is comprehensively evaluated through structural stability, material strength, and wind resistance rating tests.
1. Testing Items: These include structural stability testing (e.g., frame deformation resistance), material strength testing (e.g., steel pipe wall thickness), protective facility testing (e.g., reliability of fixing devices), and wind and earthquake resistance testing (simulating the effects of wind or seismic forces).
2. Differences in Wind Resistance Ratings:

• The mobile toilets from Anhui Zhisheng Environmental Protection use a light steel structure frame with a main steel pipe wall thickness of 2.5mm. Third-party testing has shown a wind resistance rating of Level 10 (wind speed approximately 24.5-28.4m/s), with no frame deformation or weld cracking after severe convective weather.
• Mobile toilets using an integrated molding process have a wind resistance capability of up to Level 12 (GB/T 29737-2013 standard, wind speed approximately 32.7-36.9m/s), making them suitable for areas frequently affected by typhoons.
• Products from Shandong Hengtong have a main steel pipe wall thickness of 2mm and a wind resistance rating of Level 8 (wind speed approximately 17.2-20.7m/s). After severe convective weather, slight frame displacement was observed, requiring reinforcement.
• Products from Henan Yuzhijie and Jiangsu Huajie have wall thicknesses of 2.2mm and 2.1mm, respectively, with a wind resistance rating of Level 9 (wind speed approximately 20.8-24.4m/s). While no significant deformation was observed, a small amount of rust appeared at the welds, indicating the need for enhanced corrosion protection.
  3. Structural Optimization: The wind resistance of light steel structure frames can be improved by increasing the wall thickness of steel pipes and optimizing node connection methods (e.g., welding or bolt fixation). Additionally, bottom fixing devices (such as ground anchors or counterweights) can prevent the toilets from being overturned by strong winds.
