Cangnan Construction Site Portable Toilet Installation

The installation of portable toilets at construction sites in Cangnan requires comprehensive control from planning to acceptance, with a focus on the following aspects:

1. Pre-installation Preparation

• Site Planning: Survey the installation location in advance to avoid underground pipelines (such as water, electricity, and communication lines) and prevent damage during later construction. The ground should have a drainage slope of ≥3° to ensure natural drainage of sewage. Also, check whether the sewage pipes are unobstructed and remove debris such as sand and waste paper to prevent blockages.
• Ground Treatment: The installation site should be level. If the ground is soft, it should be compacted or a concrete foundation should be laid to prevent toilet settlement or tilting.

2. Size and Capacity Matching

• Headcount Estimation: Configure the number of toilets based on the density of personnel at the construction site. It is recommended to install one standard 1.2-meter-wide toilet for every 50 people. If the construction site has high mobility, modular toilets should be selected for easy and quick installation, disassembly, and relocation.
• Spatial Layout: Reserve sufficient aisle space (a recommended width of ≥1.5 meters) to avoid congestion during peak usage. If it is a multi-story structure, ensure the safety of staircase load-bearing.

3. Functional Configuration

• Basic Functions: A flushing system must be equipped, with priority given to water-saving types (such as foot-operated flush valves) to reduce water costs.
• High-end Requirements: If the construction site has high environmental requirements, odor removal devices (such as activated carbon filters), aroma systems, or intelligent ventilation devices can be added to maintain fresh air. Anti-odor floor drains can effectively isolate the backflow of odors.

4. Material Selection

• Frame Structure: Due to the humidity in coastal areas, it is recommended to use a steel frame structure with SMC panels, which have strong corrosion resistance. If safety is also a concern, special waterproof materials (such as galvanized steel plates) and anti-slip floors (such as PVC materials) can be selected to reduce the risk of slipping.
• Sealing: Waterproof glue or rubber pads should be used for bottom sealing to prevent sewage leakage and soil pollution.

5. Installation Acceptance Standards

• Qualification Review: The supplier should provide 3C-certified water and electricity systems and anti-leakage test reports to ensure material compliance.
• Load-bearing Test: After installation, a load-bearing test should be conducted by simulating a uniform pressure of 200 kilograms (such as stacking sandbags) to ensure structural stability.
• Function Inspection: The flushing system, ventilation devices, and lighting equipment should be debugged one by one to ensure normal operation.

6. After-sales Service

• Warranty Period: Prioritize suppliers that offer a 5-year warranty covering core components such as frames and panels.
• Response Speed: Require a 24-hour maintenance response to minimize downtime caused by failures.
• Case References: Review similar project cases completed by the supplier in the Cangnan area in the past six months to assess their implementation capabilities.

7. Installation Process

• Locate the Sewage Pipe: Determine the position of the toilet feet based on the center of the sewage pipe, with an error margin of ±2 centimeters.
• Fix the Feet: Pre-embed expansion screws (with a depth of ≥10 centimeters) to ensure a firm connection between the toilet and the ground.
• Sealing Treatment: Apply waterproof glue at the contact point between the feet and the ground to prevent sewage leakage.
• Function Debugging: After installation, test the flushing, ventilation, lighting, and other systems, and clean up internal debris.
