Longnan Simple Mobile Toilet Installation

The installation of simple mobile toilets in Longnan requires comprehensive planning based on terrain, materials, drainage, and maintenance needs. The specific steps are as follows:

I. Pre-installation Preparation

1. Site Inspection: Ensure that the sewage pipes are not blocked and that the toilet installation position is level with the ground to avoid drainage issues later.
2. Foundation Adaptation: In the hilly terrain of Longnan, it is crucial to evaluate the stability of the foundation structure. If using galvanized steel plates or fiberglass materials, ensure that the ground is level and has sufficient load-bearing capacity; for soft soil foundations, reinforcement measures (such as pouring a concrete base layer) are required.
3. Accessibility Planning: The toilet location should be at a reasonable distance (usually no more than 50 meters) from the main road to facilitate equipment transportation and daily maintenance.

II. Drainage System Installation

1. Short-distance Relocation: Use an oval flat pipe relocator (approximately 60mm in height), chisel out 20~40mm of the ground floor slab, and then embed it. Connect to the existing sewage pipe and extend it to the target location. Key Parameters: The pipe slope should be ≥3% (when the relocation distance exceeds 300mm) to prevent sewage backflow.
2. Same-floor Drainage: If the building already has a dropped ceiling structure (250mm350mm), the pipe layout can be directly planned; without a dropped ceiling, a raised platform of 180mm200mm should be constructed, and the sewage pipe should be embedded with proper waterproofing.
3. Inter-floor Drainage: It is necessary to negotiate with the downstairs residents to modify the top pipes and install a water trap (with a water seal height of ≥50mm) to prevent odor backflow.

III. Material and Structural Reinforcement

1. Box Material: Prioritize the use of rust-resistant galvanized steel plates or fiberglass. The surface coating should have anti-slip and stain-resistant properties; internal partitions and accessories (such as door locks and handrails) should be made of moisture-resistant materials to prevent mildew.
2. Frame Structure: The bottom should be welded with I-beams, and the columns should be square welded structures to ensure overall stability; in mountainous installations, additional diagonal braces or anchors should be added to resist terrain inclination risks.

IV. Sewage Treatment and Intelligent Configuration

1. Treatment Method Selection:
   • Biodegradation: Suitable for areas with high foot traffic and strong environmental carrying capacity, where organic matter is decomposed by microorganisms;
   • Chemical Decomposition: Add special agents to accelerate decomposition, suitable for low-temperature or low-frequency use scenarios;
   • Physical Storage: Use sealed containers for regular removal, requiring large-capacity fecal storage tanks (recommended ≥500L).
2. Intelligent System: Optional installation of induction lighting, ventilation equipment, and remote monitoring modules to monitor usage status in real-time (such as overflow alarms and energy consumption monitoring) and improve operational efficiency.

V. Maintenance and Dynamic Adjustment

1. Daily Cleaning: Use neutral environmentally friendly cleaning agents to avoid corroding materials; replace vulnerable parts (such as seals and filters) every three months.
2. Quantity Configuration: Calculate the number of toilet units based on dynamic foot traffic data, and temporarily add modular units during peak periods (such as configuring one toilet per 50 people).
