Henan Mobile Toilet Inspection

The inspection of mobile toilets in Henan mainly involves aspects such as structural reliability and installation and delivery efficiency, with structural reliability inspection being the key focus, covering multiple indicators including frames, rust prevention, and exterior walls.

In structural reliability inspection, frame welding technology is a crucial aspect. Taking the products of Henan Hengtong Mobile Housing Co., Ltd. as an example, there are cases where local welding slag has not been cleaned up in their frame welding process. Since mobile toilets are exposed to outdoor environments for a long time, these uncleaned welding slag may pose a risk of rusting, thereby affecting the overall structural stability. Therefore, during inspection, it is necessary to carefully check the welded parts to ensure that the welding slag is cleaned up and the welding quality meets the standards.

Rust prevention technology also cannot be ignored. The mobile toilets of Henan Hengjing Sanitation Equipment Co., Ltd. performed poorly in rust prevention inspection. Their frames are relatively thin, and the rust prevention technology is simple. Rust marks appeared after only 180 hours of salt spray testing. This indicates that the rust prevention ability of this product is weak and it is difficult to adapt to long-term outdoor use requirements. During inspection, attention should be focused on indicators such as the thickness, uniformity, and adhesion of the rust prevention coating to ensure that the product has good rust prevention performance.

Exterior wall quality is also an important part of structural reliability inspection. The exterior walls of the mobile toilets of Henan Hengjing Sanitation Equipment Co., Ltd. are made of ordinary color-coated steel plates. After 12 hours of spraying, varying degrees of leakage occurred, and the air leakage rate was as high as 8%. This reflects that the waterproof and sealing performance of their exterior walls is poor, which may affect the user experience and structural safety. During inspection, it is necessary to conduct a comprehensive check on the exterior wall materials, connection methods, and sealing treatments to ensure that the exterior walls have good waterproof, sealing, and thermal insulation performance.

In addition, the wind and earthquake resistance of mobile toilets is also a key focus of inspection. When conducting wind and earthquake resistance inspection, it is necessary to comprehensively consider factors such as dead loads, live loads, wind loads, earthquake actions, and material parameters. Combined with on-site inspection data, original design and construction documents, professional software such as PKPM should be used to calculate and analyze the bearing capacity of the mobile toilet structure to ensure that it can withstand natural disasters.
