Installation of Mobile Toilets in Biyang County

The installation of mobile toilets in Biyang County should follow standardized procedures, combining site conditions and equipment types for scientific construction. The specific steps and key points are as follows:

I. Installation Process and Key Points

1. Preliminary Preparation

   • Site Selection: The site should be flat, well-ventilated, and away from water pollution sources (such as rivers and sewers) to avoid later pollution risks. If the ground is soil or uneven, it should be hardened in advance (e.g., by pouring concrete) or reinforced with steel plates for stability.
   • Equipment Inspection: Check whether the main frame, toilet bowls, fecal storage tanks, connectors, and other accessories are complete to avoid delays due to missing parts.

2. Foundation Fixation

   • Main Body Positioning: Place the mobile toilet at the designated location and secure the bottom with expansion screws (for hard surfaces) or counterweights (such as sandbags or stones) to increase stability.
   • Split-type Toilets: First, install the steel structure chassis, adjust it to a level position, and then fix it to ensure the verticality of subsequent wall installations.

3. Main Structure Installation

   • Split-type Toilets: Install the sandwich panel walls sequentially and secure them, then install the roof panel and perform sealing treatment (e.g., caulking to prevent leaks). Integrated toilets (such as box-type ones) have been decorated in the factory and only need to be hoisted into place on-site, with installation time reduced to 2-4 hours.
   • Time Reference: Wall installation for split-type toilets takes about 1-2 hours, while integrated toilets are more efficient.

4. Internal Facility Connection

   • Water and Electricity Installation: Connect the toilet bowl flushing system, sink (if any), lighting, and ventilation equipment. Water and electricity pipelines should be operated by professionals, and modular interfaces can shorten the time.
   • Function Testing: Check whether the flushing is smooth, the circuit is safe, and the sealing is good (e.g., no leaks at door seams and joints).

5. Auxiliary Facility Assembly

   • Install doors, windows, handrails, hooks, and other accessories, lay anti-slip mats, clean up installation residues, and place toilet paper, deodorizers, and other supplies.

II. Key Factors Affecting Installation Efficiency

• Toilet Type: Integrated box-type toilets are the fastest to install, while foldable or telescopic toilets are more efficient but slightly less durable.
• Foundation Treatment: Uneven ground requires additional hardening or adjustment, which may extend the construction period by 1-2 days.
• Supporting Facilities: Connecting to municipal sewage networks or dedicated fecal tanks requires additional construction, while waterless or biodegradable toilets can skip this step.
• Team Experience: Professional construction teams can shorten the time by 30%-50% and reduce rework risks.

III. Cost and Maintenance Recommendations

• Basic Installation Cost: Ordinary steel structure or color-steel plate toilets cost about 500-2000 yuan, while those in remote areas or requiring high-altitude hoisting may reach 2500 yuan.
• Maintenance Standards: Regularly inspect bolts and seals, replace aging materials every six months, and comply with the "Mobile Toilet Hygiene Standards" (GB/T 21239-2023).
• Localized Services: For temporary scenarios (such as exhibitions and construction sites), contact rental providers for full-process services. The contract should specify delivery time, acceptance standards, and emergency response mechanisms.
