Yuzhong Outdoor Mobile Toilet

The Yuzhong outdoor mobile toilet is an urban public service facility adapted to high-density mountainous terrain, featuring flexibility, environmental efficiency, and strong weather resistance, and meeting multi-scenario demands through rental services.

Physical Form and Mobility Design

The terrain in Yuzhong District is dominated by narrow alleys and slopes, so the standard size of a single mobile toilet is controlled at 1.1m×1.1m×2.3m, with forklift holes and lifting rings at the bottom for easy transportation by light trucks. The material is selected from aluminum alloy frames or galvanized sheets, balancing lightweight design with structural strength to prevent door lock jamming due to deformation during handling. This design effectively solves the problem of large equipment being difficult to access in mountainous terrain, ensuring rapid deployment and flexible position adjustments.

Sewage Disposal and Environmental Protection Technologies

To meet the needs of different scenarios, mobile toilets are equipped with diverse sewage disposal systems:

• Independent collection tanks: With a capacity of 120L-200L, suitable for temporary events or low-traffic areas, requiring regular emptying.
• External sewage pipes: Directly connected to municipal sewage networks, reducing the frequency of emptying and suitable for long-term fixed locations.
• Advanced environmental protection technologies: Some models integrate foam sealing (with a flush volume as low as 0.3L per use) or microbial degradation technologies, reducing odors and pollution through biological decomposition. These are particularly suitable for high-traffic core areas such as Jiefangbei and Hongya Cave, requiring large-capacity fecal storage tanks to extend emptying intervals and minimize traffic impact.

Weather Resistance and Fire Safety Standards

To cope with extreme weather in Chongqing, the walls of mobile toilets use EPS or rock wool insulation layers, with fluorocarbon paint or PE coatings on the exterior, achieving a fire rating of B1 or above according to the Code for Fire Protection Design of Buildings. This design can withstand summer temperatures up to 40°C and winter cold and dampness, preventing wall softening and cracking while ensuring odor-free interiors and long-term safety.

Rental Services and Multi-Scenario Applications

Yuzhong District offers mobile toilet rental services covering various types such as epidemic prevention centers, portable, and outdoor models, suitable for scenarios like construction sites, music festivals, and marathons. For example, in the "Two Rivers and Four Banks" improvement project, the sanitation support provided by temporary mobile toilets directly affects construction progress; during old sewage pipe renovations, their flexible deployment avoids restroom access issues caused by the removal of fixed toilets.

In summary, the Yuzhong outdoor mobile toilet, through modular design, integration of environmental protection technologies, and scenario-based services, has become an important support for the public service system in high-density mountainous cities.
