Zhangjiakou Outdoor Mobile Toilet
The Zhangjiakou outdoor mobile toilet is a sanitation facility designed based on environmental adaptability and resource efficiency, suitable for various scenarios, featuring cold resistance, wind and sand resistance, and easy maintenance.
I. Core Structure and Material Characteristics
The core structure of the Zhangjiakou outdoor mobile toilet includes a water storage system, a waste treatment unit, and a spatial isolation module. The exterior wall panels are mostly made of fiberglass-reinforced plastic (FRP) or galvanized steel sheets: FRP has strong corrosion resistance and is suitable for humid environments; galvanized steel sheets have excellent impact resistance and can withstand external collisions. The internal piping system uses polyethylene material, which can withstand temperatures as low as minus twenty degrees Celsius, ensuring normal operation in winter. The anti-slip floor is designed with embossed aluminum sheets, with a friction coefficient still higher than 0.6 in wet conditions, ensuring safety during use. All joints are treated with silicone sealant for a second time to prevent material deformation and cracking due to temperature changes.
II. Climate Adaptability Design
In response to the cold winters and frequent wind and sand in Zhangjiakou, the equipment is equipped with freeze-resistant water supply pipelines, wrapped with a layer of polyurethane insulation material no less than 30 millimeters thick to prevent pipeline freezing and cracking. The ventilation system adopts a bidirectional air exchange mode: natural convection is the main method in summer, and a low-power warm air circulation device is activated in winter to maintain internal air circulation. Air inlets and outlets are equipped with washable filters with a pore size no larger than 0.5 millimeters to effectively block the intrusion of wind and sand. The power supply uses a combination of solar panels and battery packs, which can maintain the operation of the basic lighting system for more than 72 hours under continuous cloudy conditions.
III. Installation and Layout Specifications
The floor area of a single unit is controlled between 1.2 meters × 1.2 meters and 1.5 meters × 1.8 meters, with the number of combinations determined according to the density of users. The layout methods are divided into linear and circular arrangements: linear arrangements are suitable for narrow construction areas, while circular arrangements can optimize pedestrian flow efficiency in concentrated usage areas. The distance between equipment is maintained within the range of 0.8 meters to 1.2 meters, with the flatness error of the ground foundation not exceeding 5 millimeters and the inclination controlled within 1% to ensure equipment stability.
IV. Cleaning and Maintenance Standards
Daily cleaning is divided into three levels: basic cleaning involves surface disinfection every 4 hours, deep cleaning involves handling the internal waste collection device daily, and excellent cleaning involves pipeline flushing and filter replacement weekly. The disinfectant is selected as a quaternary ammonium compound, which remains active in low-temperature environments and has low corrosiveness to metal materials. Solid waste is classified and treated: degradable materials are sent to professional composting facilities, and non-degradable materials are disposed of according to local regulations. Liquid waste must undergo three-stage treatment in a sedimentation tank before discharge, reducing the suspended solids concentration to below 50 milligrams per liter.
V. Style and Brand Selection
The Zhangjiakou outdoor mobile toilet offers a variety of styles and is suitable for rental services in scenarios such as marathons, concerts, music festivals, and construction sites. Manufacturers include brands such as Jiayong Zhongzhile, Hongzhaoyuxin Weiye, and Hema, with prices ranging from several hundred yuan to tens of thousands of yuan, and applicable temperature ranges covering -40℃ to 60℃, allowing for selection based on specific needs.
