Installation of Mobile Toilets in Garages

The installation of mobile toilets in garages requires comprehensive consideration of various factors. Here are the specific key points:

Purpose and Significance of Installation Mobile toilets fill the functional gaps in underground spaces through modular design, decoupling the 'toilet' space from the fixed pipeline network of traditional buildings to form an independent functional module. Their core value lies in addressing the lack of sanitation facilities in underground garages caused by their enclosed nature, constant temperature, and separation from ground-level building structures, thereby improving space utilization and user experience.

Installation Locations

1. Underground Garages: Avoid main traffic lanes, fire exits, ventilation shaft openings, and electrical equipment. Prioritize locations near staff rest areas or entrances/exits to ensure no interference with vehicle and material flow. Assess ground flatness, overhead pipeline obstructions, and accessibility for waste removal vehicles.
2. Construction Sites: Install in conspicuous areas or corners, equipped with guiding signs for quick location by personnel.

Quantity of Installation

1. Construction Sites: Configure according to the standard of 50 people per toilet stall.
2. Underground Garages: Estimate using the formula 'Required number of toilet stalls ≈ (Peak number of people × Average toilet time) / Effective working hours per shift' to avoid over-configuration leading to resource waste or under-configuration failing to meet demand.

Structure and Materials

1. Outer Shell and Structural System: Use high-strength fiberglass or polyethylene materials molded in one piece, with corrosion resistance and leak-proof properties. The structural design must adapt to the floor height and column grid spacing of underground garages, with forklift slots or pulley systems at the bottom for easy transportation and installation.
2. Maintenance Structure: Must use non-combustible materials (such as galvanized iron sheets filled with rock wool) to ensure fire safety.

Waste Disposal Methods

1. Biodegradable Type: Accelerate solid waste decomposition through microbial agents.
2. Chemical Coagulation Type: Use chemical agents to convert liquids into gel-like solids, reducing odors and waste removal frequency.
3. Vacuum Adsorption Storage Type: Use negative pressure technology to collect waste into sealed storage tanks.
4. Other Types: Include water flush and waterless flush suction types, circulating water flush types, dry packing types, etc., to be selected according to actual needs.

Auxiliary Support Subsystems

1. Forced Ventilation System: Maintain negative pressure inside to prevent odor leakage.
2. Lighting System: Meet lighting needs in underground environments.
3. Limited Clean Water Reserve System: Used for flushing toilets or washing hands, with some high-end models integrating waterless flushing technology.
4. Exhaust Grilles: The maintenance structure must be equipped with exhaust grilles, and projects with conditions can add exhaust fans.

Other Installation Requirements

1. If there is a sewage pipeline connected to a septic tank or municipal sewer network at the construction site, install water flush mobile toilets and equip them with handwashing basins.
2. During garage construction, add bamboo mat protection to the roof of mobile toilets within the tower crane range.
3. Mobile toilets inside buildings can be dry toilets, but they must be cleaned by dedicated personnel and emptied daily.
4. Post distribution maps and guiding route maps in conspicuous positions on elevators and floors to enhance convenience of use.
