Luoyang Mobile Toilet Construction Plan

The construction plan for mobile toilets in Luoyang should be systematically planned from four aspects: site preparation, equipment installation, winter maintenance, and responsibilities of both parties. Details are as follows:

I. Site Preparation Before Installation

1. Inspection of Foundation Flatness
The ground must be flat and have a reasonable drainage slope (recommended 0.5%-1%) to prevent water accumulation and freezing. If the ground conditions are poor, crushed stone can be laid or a plain concrete foundation (thickness ≥ 10 cm) can be poured to enhance stability. For example, in the low-temperature environment of Luoyang in winter, the concrete foundation needs to reserve curing time to ensure that the strength meets the standard before installing the equipment.
2. Power Supply and Drainage Connection
Confirm the location of nearby power outlets in advance. It is recommended to equip an independent distribution box (rated current ≥ 16 A) to ensure the safety of the equipment's power supply. Drainage pipes need to reserve anti-freezing measures: the buried depth of the pipes should exceed the thickness of the local frozen soil layer (the frozen soil layer in Luoyang is about 0.5-0.8 meters). The exposed parts should be wrapped with insulation cotton that is ≥ 5 cm thick, and the interfaces should be sealed with aluminum foil tape to prevent the infiltration of cold air.

II. Core Steps of Equipment Installation

1. Main Body Fixation
Use expansion bolts (specification M12×100) or concrete pouring to fix the equipment base to ensure an anti-wind rating of ≥ 8. If installed on soft soil foundations, the foundation area needs to be expanded or ground anchors need to be added to prevent equipment displacement due to low-temperature shrinkage.
2. Pipe Anti-freezing Treatment
All exposed drainage pipes (including elbows and tees) need to be wrapped with rubber-plastic insulation cotton (density ≥ 40 kg/m³), and the interfaces should be wrapped with special tape for more than 3 layers. An anti-freezing valve (temperature resistance of -30°C) should be installed at the end of the drainage pipe. During non-use periods in winter, the water in the pipe can be manually drained to prevent freezing and cracking.

III. Key Points of Winter Use and Maintenance

1. Activation of the Heating System
Priority should be given to equipment with electric heating (power ≥ 2 kW) or fuel heating devices to ensure that the indoor temperature is ≥ 5°C. When the temperature is below -5°C, the operating status of the heating system needs to be checked daily, with a focus on observing the sensitivity of the thermostat and the reliability of the circuit connections.
2. Daily Inspection
Clean the snow and ice residue in the toilet every day to keep the ground dry; check the tightness of the water tank and valves every week, and immediately replace the sealing rings if leakage is found. If the equipment is out of use for a long time, the water tank needs to be drained and the main valve needs to be closed to prevent pipe freezing and blockage.

IV. Precautions for the Lessor and the Lessee

1. Responsibilities of the Lessor
Provide anti-freezing equipment that meets the climatic conditions in Luoyang (such as a double-layer insulation structure with a wall thermal conductivity coefficient ≤ 0.03 W/(m·K)). After installation, detailed operating instructions and a 24-hour emergency contact number need to be provided.
2. Instructions for the Lessee
Avoid stacking debris within 1 meter around the toilet to ensure that the ventilation openings are unobstructed; if abnormal conditions such as slow drainage or odors are found, immediately contact the lessor for handling. It is strictly prohibited to disassemble the equipment or modify the pipe layout without permission.
