Wuhan Scenic Area Mobile Toilet Solution

The mobile toilet solution for Wuhan scenic areas needs to be comprehensively designed based on the tourist flow, environmental characteristics, and usage requirements of the scenic areas, covering aspects such as type selection, material and craftsmanship, functional configuration, construction and installation, sewage disposal and water replenishment, and environmental adaptability. Details are as follows:

I. Mobile Toilet Type Selection Depending on the duration of activities and tourist flow in the scenic area, two types of mobile toilets can be selected:

1. Trailer-mounted Mobile Toilets: Suitable for scenic areas with long-duration activities and high tourist flow, such as large-scale festivals or peak seasons in main scenic spots. They have a large capacity and can integrate additional facilities such as handwashing stations and independent sewage disposal systems to enhance the user experience.
2. Independent Container-structured Mobile Toilets: Ideal for short-term high-traffic scenarios, such as temporary exhibitions or weekend tourist peaks. They have a compact structure, with integrated toilets, sewage storage tanks, and ventilation devices inside, facilitating rapid deployment and turnover.

II. Materials and Craftsmanship

1. Material Selection Based on Environment:
   • Coastal scenic areas require corrosion resistance, with priority given to space aluminum or anti-corrosion wood.
   • Large-scale events require lightweight materials, with steel structures adopted to reduce transportation and installation difficulties.
2. Craftsmanship Ensuring Durability:
   • The frame is fully welded and reinforced, with anti-corrosion and rust-removal spraying covering the entire process.
   • The sealing and gluing process must be repeatedly verified to ensure no leakage in the container, adapting to Wuhan's rainy climate.

III. Specifications and Functional Configuration

1. Differentiated Specification Design:
   • Standard Type: Includes a toilet and a simple handwashing device to meet basic needs.
   • Barrier-free Type: Adds handrails, low-position sanitary ware, and widened doorways to serve special populations.
   • Type with Handwashing Station: Integrates an independent handwashing basin and an external water supply interface to improve hygiene conditions.
2. Functional Module Optimization:
   • The recommended capacity of the sewage storage tank is 200-500 liters to reduce the frequency of emptying.
   • The ventilation system can choose between natural ventilation (top exhaust vents) or mechanical ventilation (low-noise exhaust fans) to control odors.
   • The interior is equipped with a toilet seat, hooks, a paper towel holder, etc. Some devices can be fitted with automatic deodorant dispensers.

IV. Construction and Installation

1. Foundation Construction:
   • The foundation needs to be compacted with plain soil (compaction coefficient ≥ 0.93), with a C20 concrete cushion poured (100mm thick, with bidirectional steel bars) and anchor bolts pre-embedded.
   • The drainage system pre-embeds DN110 UPVC pipes (with a slope of 3‰) and sets up sedimentation wells and anti-odor traps.
2. Main Structure:
   • The frame is welded with channel steel and square tubes, with the walls installed in layers with calcium silicate boards, polyurethane insulation layers, and metal carved panels.
   • The roof is laid with SBS waterproofing membranes to ensure rainproof performance.
3. Installation Requirements:
   • Transportation requires box trucks and lifting tailgates, with a site flatness error ≤ 3cm/㎡.
   • The fixing method can choose between expansion bolts or ballast weighting to avoid damaging underground pipelines.

V. Sewage Disposal and Water Replenishment System

1. Sewage Disposal Methods:
   • Vacuum suction is used in areas without a sewer network, with regular cleaning by sewage suction trucks.
   • Gravity flow discharge is selected in areas with sewage disposal interfaces, requiring confirmation of standard site interfaces.
2. Water Replenishment System:
   • Self-contained water tank types can be chosen for remote areas, with manual regular water replenishment.
   • Direct connection to the water supply network in areas covered by municipal services, with automatic water level control via float valves.

VI. Environmental Adaptability Design

1. Hot Season: Install deodorizing devices in the sewage storage tank to suppress fermentation odors.
2. Rainy Season: Strengthen the container's sealing to prevent rainwater infiltration and resulting circuit failures.
