Jiaozuo Mobile Environmental Toilet Inspection

The inspection of mobile environmental toilets in Jiaozuo should be carried out from three aspects: the qualifications of the inspection agency, the inspection of common problems, and the key points of inspection related to construction requirements.

Regarding the qualifications of the inspection agency: Anhui Jingyi Construction Engineering Inspection Co., Ltd. holds various certificates, including the Construction Engineering Quality Inspection Agency Qualification Certificate, Laboratory Accreditation Qualification, Class B Surveying and Mapping Qualification Certificate, and Inspection and Testing Agency Qualification Certificate. It can conduct reliability appraisals of mobile toilets, and its inspection area covers Jiaozuo, Henan, among other places. Choosing such a qualified agency can ensure the authority and accuracy of the inspection results.

Inspection of common problems with mobile toilets:

• Structural stability: Check whether the foundation is loose, whether the number of counterweight blocks is sufficient and evenly placed, and whether the locking devices of the mobile wheels are effective. Examine the frame for deformation or cracking, such as bending of columns and beams caused by collisions during transportation or hoisting, and whether the welding joints are fully welded. Evaluate the wind resistance, check whether windbreak cables are added in open outdoor areas, and whether strong winds are likely to cause overturning risks when the height of a single toilet compartment is ≥ 2.2m.
• Waterproofing and corrosion resistance: Check whether the sealant at the joints of the roof and walls is aged or cracked, and whether the doors and windows are tightly sealed to prevent rainwater leakage, which could lead to rusting of the base plate and mildew of the interior decoration. Check whether the thickness of the anti-corrosion coating on the metal frame meets the standard (≥ 80μm) to avoid rusting in humid outdoor environments, especially paying attention to the bottom, splicing joints, and the area around the sewage outlet. Pay attention to whether the PVC panels and plastic components show signs of material aging.

Key points of inspection related to the construction requirements of environmental toilets:

• Environmental protection standards: They should comply with the latest national and Jiaozuo municipal environmental protection standards and technical requirements. For example, if the microbial decomposition-type ecological toilet technology is adopted, the treatment capacity of the high-efficiency composite microbial flora for excrement, the decomposition products, and the system temperature control should be inspected.
• Structural performance: Different structural materials such as the house body, walls, roof, and floor should be inspected separately for their thermal insulation, fire resistance, corrosion resistance, sound insulation, waterproofing, heat insulation, anti-slip, wear resistance, and ease of cleaning. Also, check whether the overall design's wind resistance rating, earthquake resistance rating, and adaptability to ambient temperature meet the standards.
• Water and energy conservation: Inspect the water-saving rate and flushing volume of different parts such as hand-washing basins, urinals, and toilet seats. Check the energy-saving effect of the lighting system, which uses LED energy-saving lamps with light-sensing control, and whether the power supply system can meet the basic power demands and operate normally during continuous rainy weather.
• Intelligent management: Inspect whether intelligent monitoring systems, intelligent ventilation systems, intelligent lighting systems, unmanned management systems, etc., can achieve their corresponding functions.
