Setting Up Portable Toilets
Setting up portable toilets requires comprehensive consideration of application scenarios, configuration ratios, size specifications, technical solutions, structural materials, functional configurations, environmental adaptability, and usage norms.
Application scenarios should be selected based on actual needs. On construction sites, they can be flexibly placed in areas such as tower cranes and steel processing zones according to the construction progress. In logistics parks, it is recommended to configure them in densely populated areas such as main roads and loading/unloading zones. In tourist attractions, they should be distributed according to tourist movement patterns to avoid affecting the landscape. For large-scale events, they should be concentrated according to pedestrian density to ensure rapid evacuation.
Configuration ratios should be scientifically planned. The ratio of male to female squatting (sitting) positions should be 1:1 or 3:2 to avoid long queues for women. Enterprises and institutions should configure toilet positions at a ratio of 1:15-1:20 based on the number of personnel. Logistics parks should configure 2-3 toilet positions for every 100 workers. For large-scale events with 1,000 people, it is recommended to configure 10-15 toilet positions (including urinals) and reserve emergency toilet positions.
Size specifications should conform to ergonomics. Each squatting position should measure 1.00-1.20m × 0.85m-1.20m, while urinal stations (including urinals) should measure 0.70m (depth) × 0.65m (width), with a spacing of 0.80m between independent urinals. Aisle widths should meet passage requirements, with 1.30m recommended for single-row squatting positions with outward-opening doors, 1.50m for double-row squatting positions, and 1.20-1.50m for aisles without doors.
Technical solutions should emphasize environmental protection and practicality. Waterless flushing types do not require connection to water supply and drainage pipes and are suitable for water-scarce areas. Foam sealing types reduce odors by covering excreta with foaming liquid. Water flushing types require connection to water supply and drainage pipes, with some products adopting rainwater collection and filtration systems and secondary flushing technology using hand-washing water to achieve water conservation.
Structural materials should balance durability and aesthetics. The frame should be welded from steel, with the bottom reinforced with channel steel or I-beams and columns supported by square steel. Wall materials can be selected from color steel plates, metal carved plates, aluminum-plastic plates, or anti-corrosion wood to meet requirements for moisture resistance, corrosion resistance, and fire resistance.
Functional configurations can enhance the user experience. Some products are equipped with intelligent systems, such as PLC data acquisition, LED toilet position monitors, and 4G remote monitoring modules, supporting mobile app control of lighting and flushing. Each squatting position should be equipped with a sturdy, corrosion-resistant hook, and clear Chinese signs must be provided at entrances and exits.
Environmental adaptability should meet extreme conditions. Portable toilets can operate normally within a temperature range of -20°C to 50°C, with a working voltage of 220V, requiring stable power supply. In northern regions, anti-freezing devices should be equipped, while in southern regions, ventilation design should be strengthened.
Usage norms should clarify operational procedures. The door latch should indicate 'Occupied' when pulled up and 'Vacant' when pulled down. Some simple toilets achieve automatic flushing of the squatting pit and water outlet from the faucet by stepping on a black ball, requiring operational instructions to be posted to avoid misuse.
