Jingmen Mobile Toilet Construction Plan

The Jingmen mobile toilet construction plan should be implemented in stages, integrating modular design, solar energy adaptation, and scenario-specific requirements, while strictly controlling quality and safety. Key points are as follows:

I. Project Positioning and Preliminary Design
The main body of the mobile toilet is constructed using steel frames or composite panels, with configurations adjusted according to the usage scenario: scenic areas require additional deodorization devices and母婴厕位 (mother-and-baby toilet stalls); construction sites emphasize collision resistance and oil stain resistance. If a solar energy system is adopted, ensure that the solar panels face south or southwest, with no obstructions around, and measure the site's solar irradiance using a sunshine recorder. Jingmen has an average annual sunshine duration of approximately 1500 hours, so the battery capacity needs to be 1.3 times that of conventional areas to cope with continuous rainy weather and ensure a toilet endurance of ≥72 hours.

II. Construction Process and Site Preparation
Construction follows the principle of "underground before above-ground, main body before decoration." First, use a total station to measure ground flatness and inspect underground pipelines (such as cables and water pipes) to avoid construction damage. For solar-powered toilets, install the solar panel brackets first, then assemble the toilet body. Construction objectives must meet four standards: main body wind resistance rating ≥ Grade 8, waterproofing with no leakage; zero casualties during construction; delivery of conventional projects within 72 hours; noise ≤ 60 decibels, and 100% waste classification.

III. Key Points for Specialized System Construction

1. Solar Energy System: Combine solar panels with controllers and deep-cycle batteries, adopting a "generate while using, store while generating" mode. The micro-flush system relies on compressed air or gravitational drop, requiring only 0.3-0.5 liters of water per flush; the vacuum negative pressure system utilizes air pressure differences for sewage discharge, consuming less electricity.
2. Sewage Discharge System: Select technology types based on the scenario. Micro-flush systems require pre-stored compressed air; vacuum negative pressure systems have high sealing requirements and need rigorous testing.
3. Intelligent Control Module: Continuously monitor battery voltage, solar panel current, and water tank level. When the voltage drops below 11.8 volts, automatically cut off non-essential loads (such as the high-speed setting of exhaust fans) while retaining lighting and flushing functions.

IV. Resource Allocation and Risk Prevention and Control
Form a specialized team of 5-8 people, clearly defining the roles of the project manager, technical leader, construction team leader, safety officer, and logistics personnel. Risk prevention and control should focus on meteorological changes (such as continuous rainy days), underground pipeline detection, and temporary facility layout to avoid construction interruptions.

V. Acceptance and Commissioning
After installation, conduct functional tests, including the stability of the flushing system, continuity of lighting and exhaust fan power supply, and sealing of the sewage discharge system, to ensure compliance with national standards and design requirements.
