Dingcheng Mobile Toilet Inspection
The inspection of mobile toilets in Dingcheng covers multiple aspects such as construction structure, safety, hygiene, electrical systems, operation, and environmental protection, conducted in accordance with various normative standards.
Construction and Structural Review
Based on the original planning documents, use a handheld laser distance meter and a 5m steel tape measure to inspect the wall layout of the restroom, the orientation and proportion of doors and windows, and the axial proportion and height of the structure.
Structural Damage and Safety Inspection
Check for aging or deformation in main load-bearing components, abnormalities at connections of stressed steel members, the reliability of connections between steel beams and columns, and defects or cracks in welds. According to relevant standards, consider various loads and data parameters, and use PKPM software for load-bearing capacity analysis. Conduct non-destructive testing of steel structure welds, and perform tensile, yield strength, and impact tests on steel materials as needed. Inspect the strength of frame materials, the stability of connecting components, and the overall structural stability. Check the effectiveness of waterproofing, wind resistance, and earthquake resistance designs using visual inspection and mechanical testing methods.
Hygiene Condition Inspection
Inspect the surfaces of toilet bowls, cleaning tools, and the sewage system, checking for blockages or leaks in the pipes. Visually inspect the interior for stains or garbage, and use bacterial culture dishes to sample and analyze bacterial conditions.
Electrical System Inspection
Check the safety of power lines, the installation positions of sockets, the working status of lighting equipment, and the waterproof performance of outdoor electrical appliances. Use voltmeters and ammeters to test the working voltage and current of electrical equipment, and conduct operational checks to assess working status.
Operation and Environmental Performance Inspection
Record abnormal noises, vibrations, etc., of the equipment, and analyze the service life and maintenance records to evaluate the overall condition. Inspect the sewage treatment system, test the effectiveness of water-saving and deodorizing devices, and check for any odors.
Appearance and Decorative Quality Inspection
Visually inspect the appearance, interior decoration, sanitary ware, and signage, ensuring that the dimensional discrepancies between the actual appearance and interior and the design are no more than 5mm. Check the flatness and adhesion of the decorative layer, the sealing of joints, and the flatness and sealing of the floor to prevent water seepage or ponding.
Wind Resistance, Sealing, Waterproofing, and Enclosure Tightness Inspection
The welding, anti-corrosion, and rust prevention treatments of the public toilet's steel structure should meet corresponding requirements, with overall wind resistance not less than Level 10, earthquake resistance not less than Level 8, and a service life of no less than 10 years. Conduct thrust tests as required. Use a water spray gun to test sealing and waterproofing performance. Test the enclosure tightness through methods such as water immersion, visual inspection, and testing of action time.
