Installation of Mobile Toilets in Huangshi Scenic Area
The installation of mobile toilets in Huangshi Scenic Area requires comprehensive consideration of construction plans, materials, processes, and service models. The specific key points are as follows:
1. Construction Plan and Site Selection Planning
Huangshi Scenic Area plans to build five new mobile toilets, with locations covering core areas such as the Mining and Metallurgy Grand Canyon Viewing Platform and the entrance to the Mining Expo Park. The total area covered is approximately 200 square meters, with each toilet occupying an area of 15-25 square meters. Site selection should be based on the distribution of tourist traffic to ensure convenience and landscape harmony. Before construction, topographic surveys must be completed, and the foundation coordinates should be determined using a total station, with an error margin controlled within ±50mm. For areas with a slope greater than 15°, slope stabilization should be achieved through the use of masonry retaining walls to ensure a level site. The foundation construction will utilize C25 concrete independent foundations, with each toilet having four foundation piers and pre-embedded M20 anchor bolts to provide stable support for subsequent frame installation.
2. Material and Equipment Configuration
The mobile toilets adopt a modular design, with the frame system welded from 8# channel steel to ensure structural strength. The walls are made of 150mm-thick metal carved panels, providing both insulation and aesthetic appeal. The roof features a three-layer construction to enhance waterproofing performance, while the floor is paved with 20mm-thick non-slip stone-plastic flooring for improved safety. The toilet system is equipped with foam-sealed squat toilets and 304 stainless steel urinals, which are water-saving and easy to clean. Sewage treatment employs a biodegradable integrated device for harmless treatment. Material selection takes into account durability, environmental friendliness, and ease of maintenance.
3. Construction Process and Installation Techniques
The construction process is divided into three stages:
- Foundation Stage: After completing topographic treatment and concrete pouring, curing must be carried out until the design strength is reached before proceeding to the next step.
- Frame Hoisting: A 25-ton truck crane is used, with hoisting points set at the four corners of the structure and a hoisting height of 3.5m to ensure the frame is positioned smoothly. After hoisting, the levelness and perpendicularity must be calibrated, with an error margin not exceeding ±3mm.
- Equipment Installation: Walls, roofs, floors, and toilet systems are installed sequentially. Water and electricity pipelines are connected, and the sewage treatment equipment is debugged. Finally, a leak test is conducted to prevent leakage.
4. Leasing and Installation Service Model
Local service providers in Huangshi offer a one-stop 'leasing + installation' service, with professional teams capable of completing plan communication and installation on the same day, improving efficiency by more than ten times compared to traditional toilets. Under the leasing model, flexible adjustments to the number and configuration of toilets are supported, such as adding temporary units based on holiday tourist traffic. Maintenance adopts a 'modular replacement' strategy, where faulty components can be quickly replaced to ensure restoration of service within 24 hours and reduce downtime risks.
Through scientific planning and efficient execution, the installation of mobile toilets can significantly enhance the service capacity of the scenic area while balancing environmental protection and economic efficiency.
