Mobile Toilets at Yibin Construction Sites

Mobile toilets at Yibin construction sites are integrated environmentally friendly restrooms with a container-based modular steel structure as the main body, featuring zero on-site construction, rapid commissioning, and various specifications and environmental standards.

I. Main Structure and Features Mobile toilets at Yibin construction sites adopt a factory-prefabricated, fully assembled, and finished product delivery model, with a container-based modular steel structure as the main body. Their core advantage lies in the fact that no on-site construction is required; they can be used immediately after being hoisted and connected to water and electricity supplies. They combine the structural stability, mobility, and reusability of container houses while integrating the full functionality of finished restrooms.

II. Mainstream Size Specifications

1. Mini Single-Toilet Model: External dimensions of 3000×2400×2800mm, equipped with one independent toilet cubicle and a sink, suitable for small construction sites or temporary needs.
2. 20-Foot Standard Model: External dimensions of 6058×2438×2896mm, configured with 2-4 toilet cubicles, supporting separate male and female compartments and a sink area. The reinforced version can be stacked up to 2 floors, suitable for medium-sized construction sites.
3. 40-Foot Extended Model: External dimensions of 12192×2438×2896mm, configured with 6-8 toilet cubicles, including an accessible cubicle, a management room, and a sink area, suitable for large construction sites or densely populated areas.
4. Custom Non-Standard Model: Customizable in size and functional areas according to site requirements, with flexible assembly and combination options, but must comply with the regulation that temporary buildings should not exceed 2 floors.

III. Environmental Protection and Standard Requirements

1. Anti-Seepage and Waterproofing: The container body must have a waterproof rating of no less than IP65, and the floor must undergo multiple layers of waterproofing treatment and pass a 48-hour closed water test. The sewage storage tank/septic tank must be corrosion-resistant and anti-seepage, complying with the HJ 2029-2013 standard.
2. Pollutant Discharge: When connected to the municipal sewer network, the GB 8978-1996 Level III standard shall be followed; for on-site reuse without a sewer network, the GB 18918-2002 Level I A standard shall be followed; for zero-discharge models, fecal matter must meet the harmless treatment requirements of GB 7959-2012; odor emissions shall comply with the GB 14554-1993 Level II standard, with an indoor ammonia concentration of ≤0.3mg/m³.
3. Water Conservation and Environmental Protection: For conventional water-flush toilets, the single-flush volume shall be ≤6L, and for water-saving models, it shall be ≤4L; for foam-sealing toilets, the single-flush water consumption shall be ≤0.1L, and the foaming agent must be biodegradable; for circulating water-flush toilets, the water circulation rate shall be ≥80%; for microbial degradation toilets, zero water flushing shall be achieved, with a fecal degradation rate of ≥90%.
4. Fire Protection and Electrical Safety: Enclosure materials must use Class A non-combustible rock wool sandwich panels, electrical wiring shall be laid through metal conduits, and the distribution box shall be equipped with a leakage protection device of ≤30mA; each container body must be equipped with no less than 2 4kg ABC dry powder fire extinguishers and independent smoke detectors.

IV. Land and Planning Restrictions It is strictly prohibited to set up mobile toilets in basic farmland, ecological protection red lines, or river control areas; temporary land use requires approval from the natural resources department, with a general usage period not exceeding 2 years; placement within urban areas must comply with urban appearance management regulations, and public spaces shall not be occupied without authorization; they can only be used as temporary buildings and cannot be registered for property rights.

In addition, mobile toilets at Yibin construction sites support leasing services, and several companies, such as Sichuan Jingqing Environmental Protection Technology Co., Ltd., can provide related services.
