Mobile Toilet 3+1 Structure

There indeed exists a "3+1" structural type in mobile toilets, typically referring to a combination of three standard toilet stalls and one special-function toilet stall, with specific configurations varying according to the manufacturer's design.

Common Configurations of the "3+1" Structure

The core design of the "3+1" mobile toilet lies in optimizing functional zoning. Taking the product of Hebei Shijiazhuang Nuotai Environmental Protection Machinery and Equipment Co., Ltd. as an example, its "carved panel finished 3+1 public toilet" adopts a combination of three standard toilet stalls (usually squat or sit-down units) and one special-function toilet stall. The special-function toilet stall may include a management room (for storing cleaning tools or providing rest space for staff), an accessible toilet stall (equipped with handrails, emergency call devices, and other elderly-friendly facilities), or a tool room (for storing maintenance equipment). This design not only meets basic usage needs but also enhances applicability through functional segmentation, making it particularly suitable for public places such as scenic spots and parks.

Extensibility of Modular Design

The modular design of Beijing Simple Mobile Toilets provides a flexible implementation method for the "3+1" structure. By assembling standardized toilet units, multiple toilet stalls can be quickly combined into a connected unit. For example, three standard toilet modules and one special-function module (such as an accessible toilet stall) are fixed together with bolts or clips to form an independent toilet cluster. This design not only facilitates transportation and installation but also allows for adjusting the layout direction (such as linear or L-shaped arrangements) according to site conditions, adapting to different terrain requirements.

Customization and Parameter Acquisition

Since the specific parameters of the "3+1" structure (such as stall size, material, and sewage disposal method) vary among manufacturers, it is recommended to contact the supplier directly for detailed data or customized solutions. For example, Nuotai Environmental Protection may offer options such as carved panel exterior walls, stainless steel interior fittings, and microbial degradation sewage disposal, while other manufacturers may use fiberglass materials or foam sealing technology. By communicating the usage scenario (such as average daily foot traffic and whether connection to the municipal sewage network is required), the supplier can provide more precise configuration recommendations.

Adaptability to Application Scenarios

The "3+1" structure stands out in various scenarios due to its functional balance: scenic spots can enhance service quality with accessible toilet stalls, temporary event sites can store supplies in management rooms, and remote areas can reduce sewage disposal dependence by choosing microbial degradation technology. Its modular nature also supports later expansion, such as adding toilet modules to the existing 3+1 setup to quickly upgrade to a "5+1" or larger-scale toilet cluster.
