Huaian Combined Mobile Toilet

The Huaian combined mobile toilet is a mobile sanitation facility designed with multiple toilet stalls in a trailer-mounted, gender-separated layout, suitable for high-traffic scenarios. The following provides an introduction from four aspects: type and structure, application scenarios, equipment configuration, and service scope.

Type and Structure
The combined mobile toilets in Huaian are primarily trailer-mounted, featuring an integrated design with multiple toilet stalls. Capacity expansion is achieved through modular assembly. Their core structure is a gender-separated layout, with each independent unit containing multiple squat toilets or sit-down toilets. Some high-end models are equipped with barrier-free access and baby care stations to meet the needs of special groups. For example, among the 120 units deployed for the 2024 Huaian Grand Canal Half Marathon, some were multi-stall combined models that achieved efficient use through diversion design.

Application Scenarios
These toilets mainly serve short-term, high-traffic events such as marathons, music festivals, and large exhibitions. Taking marathon events as an example, combined mobile toilets employ a deployment strategy of "fixed positions + mobile replenishment" along with on-site diversion and guidance plans, enabling zero-complaint service for events with tens of thousands of participants. Their advantage lies in rapid response capability, as they can complete equipment deployment and commissioning within 2 hours, adapting to temporary and emergency public health needs.

Equipment Configuration
Local service providers offer a full range of equipment rentals, including basic, smart, and special models:

• Basic models: Equipped with independent squat toilets, basic handwashing sinks, and manual flushing systems, suitable for budget-constrained or short-term use scenarios;
• Smart models: Upgraded with sensor-activated flushing, air conditioning, ventilation systems, and LED lighting to enhance user comfort, commonly used in high-end events or high-temperature environments;
• Special models: Equipped with barrier-free access, baby care stations, and emergency call devices to meet the needs of disabled individuals and groups with infants.
  Combined models can flexibly adjust capacity through multi-stall modular assembly, with a single unit accommodating up to 8-10 toilet stalls.

Service Scope
Service covers four districts (Qingjiangpu, Huaiyin, Huai'an, and Hongze) and three counties (Lianshui, Xuyi, and Jinhu), forming a rapid response network across the entire region. Service providers offer a full-process service of "transportation - installation - maintenance - recycling", supporting appointment-based deployment 48 hours before events and providing dedicated personnel for inspections during events to ensure normal equipment operation. For example, during the 2024 marathon event, service providers dynamically adjusted equipment distribution based on crowd density through a dynamic scheduling mechanism, effectively avoiding local congestion.
