Ezhou Construction Site Mobile Toilet
The mobile toilets at construction sites in Ezhou are important temporary facilities to ensure sanitary conditions during construction, featuring independent operation, strong adaptability, and efficient treatment.
I. Structural and Functional Design
Mobile toilets are essentially miniature sewage collection and treatment units, with core systems including a sewage storage tank, a flushing circulation device, and an odor removal system. The sewage storage tank, made of high-density polyethylene, is located at the bottom to prevent sewage leakage and soil contamination. The flushing system is mostly pedal-operated or hand-operated, with a single flush volume of only 0.3 to 0.5 liters, providing significant water-saving effects. The odor removal system adsorbs harmful gases such as hydrogen sulfide and ammonia through activated carbon filters. Meanwhile, biodegradable bacteria agents are pre-installed in the sewage storage tank to decompose odor-producing organic matter, achieving composite odor removal through physical adsorption and chemical neutralization.
II. Advantages in Construction Site Adaptability
In response to issues such as foundation settlement and incomplete water and electricity pipelines at construction sites in Ezhou, mobile toilets adopt an independent chassis structure and can be directly placed on compacted and leveled plain soil or concrete pads without the need for drainage ditch excavation or pipeline pre-embedding. The equipment is equipped with adjustable support legs at the bottom to accommodate ground slope differences within 3 degrees, ensuring stability. Rental specifications include single-person stalls (approximately 80 kilograms) and double-person stalls (approximately 120 kilograms), both equipped with lifting rings or forklift slots for easy transportation by tower cranes or forklifts, meeting the flexible layout needs of construction sites.
III. Waste Treatment and Maintenance
The rental company dispatches vacuum sewage suction trucks according to the contract period (usually 3 to 7 days) to connect to the sewage discharge valve at the bottom of the toilet through a dedicated hose and use negative pressure to suction the mixture in the sewage storage tank into the vehicle-mounted tank. After suction, workers inject clean water and add new bacteria agents to maintain treatment efficiency. Winter anti-freezing measures include a double-layer structure for the sewage storage tank (with 3 cm of polyurethane foam insulation layer filled between the inner and outer walls) and anti-freezing spring valves for the flushing pipes, which can discharge residual water when water pressure disappears to prevent pipe damage from ice expansion. The average daily water consumption of a single unit is approximately 15 to 20 liters, with low resource consumption.
IV. Service and Resource Support
There are multiple rental companies in Ezhou providing 24-hour services covering the entire region, with businesses including rental, sales, delivery, installation, waste disposal, emergency maintenance, and other additional services, enabling quick response to construction site needs.
