Mobile Toilet Process Standards

Mobile toilet process standards cover multiple aspects such as design, materials, construction, and environmental protection, as detailed below:

I. Design Standards

Spatial Layout: The interior space is generally between 1.5 and 2 square meters to meet basic usage needs. The independent unit size of mobile toilets in Beijing is typically 1.2m × 1.5m × 2.2m, which can be combined into a connected structure of 2-4 units, equipped with squatting positions, handwashing stations, storage racks, and some high-end products feature dedicated compartments for the disabled.
Climate Adaptability: Design must be tailored to the climatic characteristics of the usage area. For example, mobile toilets at construction sites in Shaanxi experience cold winters and rainy summers, so walls are made of insulating materials, floors are slip-resistant, and drainage systems are freeze-proof; mobile toilets in Beijing adapt to the northern climate through sealing and ventilation designs.
Waterproof Sealing: Seams are sealed with materials to ensure waterproof performance. Mobile toilets in Beijing use ethylene propylene diene monomer (EPDM) rubber strips for sealing, achieving an overall waterproof rating of IPX7.
Ventilation System: Silent exhaust fans are installed on the top, with an air exchange rate of ≥15 times per hour to prevent odor accumulation.

II. Material Standards

Main Frame: Mobile toilets at construction sites in Shaanxi often use stainless steel or aluminum alloy materials, which are corrosion-resistant and lightweight; mobile toilets in Beijing use high-strength aluminum alloy profiles with anodized surfaces, improving corrosion resistance by 30%.
Panels: Color-coated steel sheets (with good thermal insulation) or anti-corrosion wooden boards (with a natural style) are commonly used at construction sites in Shaanxi; mobile toilets in Beijing use SMC molded composite materials, which have a fire rating of B1, are impact-resistant, and easy to clean.
Internal Fittings: Durable and dirt-resistant products are selected at construction sites in Shaanxi, with some equipped with water-saving flushing devices; mobile toilets in Beijing are equipped with 6-liter water-saving flush valves, saving 40% of water and complying with water conservation policies.
Electrical Safety: Mobile toilets in Beijing use a 220V/50Hz external power supply, with sockets equipped with leakage protection devices and a grounding resistance of ≤4Ω.

III. Construction Standards

Construction Preparation: It is necessary to complete the "three supplies and one leveling" (road access, water supply, power supply, and site leveling) to ensure smooth transportation of construction vehicles and materials, stable water and power supplies, and a site leveling error of ≤20 millimeters per square meter.
Foundation Construction: The foundation of mobile toilets at construction sites in Shaanxi is hardened with concrete; mobile toilets in Beijing use concrete precast block foundations with a load-bearing capacity of ≥500kg/m².
Main Structure Assembly: The main frame is assembled on-site at construction sites in Shaanxi and completed on the same day; mobile toilets in Beijing are transported and hoisted using dedicated cranes with a tilt angle of ≤15°.
Water and Electricity Connection: Drainage in mobile toilets in Beijing uses PE pipes buried underground (with a diameter of ≥110mm), and interfaces undergo closed-water tests; power supply is connected to the municipal power grid with a wire diameter of ≥4mm².
Commissioning and Acceptance: Mobile toilets at construction sites in Shaanxi require airtightness tests; mobile toilets in Beijing are disinfected three times after completion and comply with the requirements of the "Regulations on the Hygiene Management of Public Places".

IV. Environmental Protection Standards

Biodegradation: Mobile toilets at construction sites in Shaanxi often use biodegradation technology, which does not require water flushing and relies on microorganisms to decompose feces.
Solar Power Supply: Some mobile toilets at construction sites in Shaanxi are equipped with solar power supply systems, suitable for scenarios without external power supply, reducing resource consumption.
