Installation of Mobile Toilets in Shaoxing Park

The installation of mobile toilets in Shaoxing Park requires comprehensive consideration of various factors, including infrastructure adaptability, installation procedures, toilet types, and supporting facilities, while strictly adhering to relevant standards and regulations.

I. Infrastructure Adaptability
Shaoxing is characterized by a dense network of rivers and waterways, necessitating mobile toilets with stringent anti-leakage designs to prevent sewage from seeping into the ground and contaminating water bodies. In the ancient city's protected areas, there are special restrictions on ground bearing capacity, requiring lightweight solutions for equipment transportation and installation to avoid damaging the foundations of ancient buildings. For instance, aluminum alloy frames or high-strength plastic materials can be selected to reduce the equipment's self-weight.

II. Installation Procedures and Technical Aspects

1. Site Assessment: Measure the terrain slope (recommended slope ≤ 5%) and soil bearing capacity (required ≥ 1.5 tons per square meter) to ensure equipment stability.
2. Equipment Allocation: Plan transportation routes and coordinate traffic control to minimize disruption to park visitors.
3. Installation Implementation:
   • Modular Toilets: After positioning the chassis and frame, use a forklift to adjust the level; insert the walls into the chassis slots and secure them with bolts; seal the roof panels to prevent rainwater leakage.
   • Integrated Toilets: After factory prefabrication, lift them onto the site and connect water, electricity, and sewage pipes (if using flushless or biodegradable toilets, sewage pipe connections can be omitted).
4. Functional Debugging: Conduct flush tests and sewage discharge tests to ensure normal equipment operation.

III. Toilet Types and Installation Convenience

1. Integrated Box-Type Toilets: These offer the fastest installation and dismantling (completed in 2-4 hours) and have the lowest requirements for on-site construction, making them suitable for emergency needs or temporary events.
2. Modular Toilets: These require on-site assembly and take longer (about 1 day), but allow for flexible adjustment of the internal layout.
3. Double-Occupancy Mobile Toilets: The focus is on rapid positioning and functional connection, without involving civil construction. However, the lessee must provide a flat and solid site (slightly larger than the equipment itself).

IV. Supporting Facilities and Maintenance
If connection to the municipal sewage network or a dedicated septic tank is required, installation and connection times will be extended; flushless toilets can simplify the process. Maintenance cycles include daily cleaning (disinfection, replenishment of consumables) and weekly in-depth treatment (equipment inspection, septic tank cleaning). During recycling, disinfection, sterilization, and equipment testing must be completed to ensure safety for the next use.

V. Standards and Regulations
Design and installation should refer to the "Hygiene Standards for Mobile Toilets" (GB/T 21239-2023) to ensure structural safety and hygiene compliance, such as maintaining a sewage pipe slope of ≥ 2% to prevent blockages.
