Installation of Mobile Toilets on Construction Site Floors

The installation of mobile toilets on construction site floors requires comprehensive consideration of floor layout, mobility, safety, and basic supporting facilities. The specific installation points are as follows:

I. Installation Location Planning

1. Floor Distribution: Set up mobile toilets every certain number of floors (e.g., every 7 floors) within the building to ensure that workers do not need to travel long distances during construction, thereby improving work efficiency.
2. Area Selection: For general construction sites, prioritize areas with high usage frequency, such as near the entrances and exits of living areas and work areas; avoid open-flame work areas, material storage areas, and power distribution facilities to reduce safety risks; the terrain should be flat and slightly higher than the surrounding ground to prevent water accumulation; when close to rivers or water sources, maintain a sufficient buffer distance (usually ≥10 meters) to avoid polluting the water source; at the same time, ensure that temporary roads are unobstructed for easy transportation and maintenance.

II. Foundation Treatment and Transportation Placement

1. Ground Treatment: For muddy ground, compact the soil and lay a crushed stone bedding (thickness ≥10 centimeters); for soft soil or backfilled areas, further reinforcement is required (such as piling or pouring concrete); for hardened ground, check the flatness with an error not exceeding ±5 millimeters; reserve the location of the septic tank or sewage outlet to ensure alignment with the toilet's sewage pipe.
2. Transportation and Hoisting: Use professional vehicles for transportation, and secure the container body with ropes or straps; use special hoisting straps during hoisting to avoid scratching the container body; ensure that the container body is level when placing it, with an error not exceeding ±2 degrees; operate in coordination with multiple people and under unified command to prevent tipping; the container door should face away from the prevailing wind direction and avoid major traffic channels to reduce odor diffusion and collision risks.

III. Pipe Connection and Supporting Facilities

1. Flush Toilets: Connect to the water supply pipe (preferably PPR or PE material, which is highly corrosion-resistant) and the drainage pipe (maintain a slope of 1%-2% to ensure smooth drainage); seal the joints tightly to prevent leakage; if using a water tank for water supply, regularly check the water level and quality.
2. Non-flush Toilets: Ensure that the fecal collection container is placed stably and sealed properly to avoid odor leakage; regularly clean the container to prevent blockage or overflow.
3. Ventilation and Lighting: Maintain good natural ventilation and, if necessary, install exhaust fans or ventilation pipes (diameter ≥10 centimeters); if there are no built-in lighting facilities, install them in well-lit areas; for nighttime use, connect to temporary lighting circuits, select waterproof and explosion-proof lamps, protect the circuits with pipes and fix them firmly to prevent electric shock risks.

IV. Safety Protection and Sign Management

1. Lightning Protection and Grounding: In areas prone to thunderstorms or open construction sites, mobile toilets with metal structures should be equipped with independent lightning rods (height ≥3 meters), and the metal frames should be grounded with a grounding resistance not exceeding 10 ohms to prevent lightning strikes.
2. Warning Signs: After installation, hang signs in prominent positions, including the distinction between men's and women's toilets and usage precautions; for areas close to vehicle traffic, set up warning posts or reflective stickers around them, and install warning lights when visibility is insufficient at night to prevent collisions.
