Shanghai Mobile Toilet Construction Plan

The Shanghai mobile toilet construction plan covers multiple aspects such as site selection, technology, design, operation and maintenance, and construction. Details are as follows:

Site Selection Logic: Based on data such as pedestrian heat maps, large-scale event plans, and temporary needs in old residential areas, the regions are classified and distributed with points. Along the marathon route, in "tidal" pedestrian flow areas of popular business districts, and in short-term demolition transition areas, a "plug-and-play" model is adopted, following the principle of "not interfering with the main road landscape and being accessible within a 5-minute walk" to resolve the conflict between timeliness and space.

Technological Iteration:

• Microbial Degradation Technology: Decomposes excrement into odorless liquid through bacterial colonies, achieving internal circulation and eliminating dependence on sewer networks, suitable for long-term fixed points with stable power supply.
• Packaging + Vacuum Suction Combination: For large-scale events, biodegradable packaging bags are used in conjunction with a vacuum negative pressure system to isolate odors and waste, reducing the frequency of waste removal.
• Intelligent Components: Equipped with "occupied/unoccupied" displays, automatic deodorization sprays, toilet paper level alarms, and IoT-based liquid level and battery monitoring to enhance operational efficiency.

Design Details:

• Human-Centered Design: Features one-touch emergency buttons, anti-collision rounded corners, storage shelves, and coat hooks, with at least 15% designated as "third restrooms" or barrier-free stalls; adopts an "upward supply, downward exhaust" ventilation method; modular and public-restroom-like exterior design to reduce visual intrusion, with some integrating charging ports and vending machines.

Operation and Maintenance System:

• Response Mechanism: During peak hours, waste removal and cleaning are conducted every 1-2 hours, with status reported through an inspection system; pre-set reinforcement measures and emergency cooling equipment are in place for extreme weather conditions.
• Collaborative Process: Establish a coordination mechanism with local sanitation and urban management departments.

Construction Plan (Taking a residential area in Pudong New Area as an example):

• Project Characteristics: Steel-frame mobile toilets with limited construction space requiring rational planning; high technical requirements necessitating strict quality and environmental impact control.
• Organizational Design: Establish a project management department with 20 management personnel, divided into construction, quality, safety, and other departments; form 5 construction teams totaling 200 people, covering civil engineering, steel structures, electrical work, and other specialties.
• Compilation Basis: Follow regulations such as the Construction Law and the Production Safety Law, as well as standards like the Mobile Toilet Construction and Acceptance Specifications, and implement based on design drawings and construction organization plans.
