Henan Mobile Toilet Inspection
The inspection of mobile toilets in Henan Province mainly involves aspects such as structural reliability and wind and earthquake resistance performance.
In terms of structural reliability inspection, taking the mobile toilets of Henan Hengjing Environmental Sanitation Equipment Co., Ltd. as an example, their frame thickness is relatively thin and can withstand a weight of 920 kg in the load-bearing test. However, their anti-rust process is relatively simple. In the salt spray test, rust marks appeared after only 180 hours, indicating that their anti-rust ability needs to be improved. In the waterproof sealing test, the exterior walls of Henan Hengjing's mobile toilets, which are made of ordinary color-coated steel plates, showed varying degrees of leakage after a 12-hour spray test, with an air leakage rate of 8%, indicating certain defects in their waterproof sealing performance. In addition, the products of Henan Hengtong Mobile Housing Co., Ltd. also have problems in the frame welding process, with local welding slag not being cleaned. Long-term exposure to the outdoor environment may pose a risk of rust, which in turn affects structural stability. Although there is no clear mention of actual measured data related to the wind resistance grade of the main frame of its products, it can be inferred from the welding process problems that there may be certain hidden dangers in terms of structural stability.
In terms of wind and earthquake resistance inspection, multiple factors need to be comprehensively considered during on-site investigations, including dead loads, live loads, wind loads, earthquake actions, and material parameters. Inspectors will combine on-site inspection data, original design and construction documents, and use professional PKPM software to conduct load-bearing capacity calculations and analyses of the mobile toilet structures. Through such analyses, the structural safety of mobile toilets under different load conditions can be evaluated, and it can be determined whether they can withstand corresponding wind and earthquake forces, thus ensuring the safety and stability of mobile toilets during use.
Overall, the inspection of mobile toilets in Henan Province requires a comprehensive evaluation from multiple dimensions to ensure that their structural reliability and wind and earthquake resistance performance meet relevant standards and requirements.
