Qiannan Intelligent Mobile Toilet Installation

The installation of intelligent mobile toilets in Qiannan needs to combine the general principles of intelligent toilets and mobile toilets and make appropriate adjustments according to the local climatic characteristics. The specific key points are as follows:

I. Pre-construction Preparations

1. Site Selection: Give priority to areas with flat terrain and good drainage, and avoid low-lying areas prone to waterlogging. Qiannan Prefecture is rainy and humid, so it is necessary to ensure that the installation location is 10-15 cm higher than the surrounding ground to prevent rainwater backflow.
2. Foundation Treatment: For ground installation, the soil needs to be compacted and a 10 cm thick concrete cushion should be laid. For floor installation, it is necessary to confirm the load-bearing capacity of the floor slab (it is recommended to be ≥300 kg/㎡), and reinforce the structure if necessary.
3. Pre-embedding of Water and Electricity:
   • Electric Circuit: Reserve an AC220V power supply. The socket should be concealed and installed at a height of 30-40 cm on the side wall of the toilet. It is recommended to install a waterproof box.
   • Water Pipeline: The water inlet angle valve should be pre-embedded before tiling. The height of the water outlet should be 15-20 cm from the ground, and a check valve should be installed to prevent sewage backflow.

II. Core Installation Steps

1. Connection of the Sewage Discharge System:
   • Water-flush Type: If connected to the municipal sewage network, measure the hole distance of the sewage outlet (commonly 305 mm/400 mm). Before installation, empty the sediment in the pipeline and use a thickened flange ring for sealing.
   • Dry Seal/Microbial Type: Check the sealing of the packing bag or the microbial reaction chamber to ensure that the mechanical transmission device is well lubricated.
2. Fixing of the Main Structure:
   • Use galvanized steel plates or stainless steel materials. Fix the toilet frame to the foundation with expansion bolts, with a bolt spacing of ≤50 cm.
   • Use waterproof sealant to treat the joints, with a joint width of ≤3 mm.
3. Debugging of the Intelligent System:
   • Test the sensitivity of functions such as sensor flushing, automatic ventilation, and lighting to ensure normal operation in an environment with a humidity of ≤85%.
   • Check the insulation performance of the electrical circuit. The grounding resistance should be ≤4 Ω.

III. Environmental Adaptation and Maintenance

1. Anti-corrosion Treatment: The average annual humidity in Qiannan Prefecture exceeds 75%. Metal parts need to be sprayed with epoxy zinc-rich primer and covered with an anti-rust paint layer.
2. Waterproof Reinforcement: The roof should use PVC waterproof rolls with a slope of ≥5%. The ground should be paved with anti-slip floor tiles, and the joints should be filled with waterproof mortar.
3. Regular Inspections: Clean the sewage discharge pipeline every quarter and replace the flange ring gasket every year. During the humid season, test the waterproof performance of the intelligent module every month.

IV. Precautions If it involves complex terrain or large-scale intelligent mobile toilets, it is recommended to contact local manufacturers in Qiannan Prefecture (such as a certain environmental protection equipment company in Duyun City) to provide customized construction plans to ensure compliance with the requirements of the "Standard for the Setting of Urban Environmental Sanitation Facilities" (CJJ/T 47-2016).
