Tianjin Public Mobile Toilet Installation

The installation of public mobile toilets in Tianjin should follow the following key steps and specifications:

I. Pre-transport Preparation

1. Demand Confirmation and Site Survey: It is necessary to clarify the model, quantity, and installation location of the mobile toilets, with a focus on assessing site flatness, space adequacy, obstacle distribution, and vehicle traffic conditions. For example, scenic spot projects need to reserve space for lifting operations to avoid obstructions from trees or fences.
2. Equipment Inspection and Reinforcement: Before loading, inspect the integrity of the box structure and the functionality of internal facilities (such as water and electricity systems), secure movable components, and lock the doors to prevent damage from shaking during transportation.
3. Vehicle and Route Planning: Select flatbed trailers or low-chassis trucks based on the equipment size (e.g., standard sizes are 1.2m×1.5m or 1.5m×2m). When planning routes, avoid height-restricted, weight-restricted sections, and bridge and tunnel passage restrictions.

II. Transportation Process Management

1. Standardized Loading and Fixing: Use lifting equipment to load the vehicle steadily, ensuring a stable center of gravity. Fix the vehicle at multiple points with straps and chains to prevent rollover or sliding.
2. Smooth Driving and Monitoring: Drivers should avoid rapid acceleration and braking. For long-distance transportation, check the fixing devices and the condition of the box halfway to prevent loosening due to bumps.

III. Installation and Commissioning

1. Site Re-survey and Positioning: Clear debris and ensure the ground is flat. Mark the placement position and orientation according to the plan. Scenic spot projects should consider the rationality of tourist movement routes.
2. Foundation Construction: Prefabricate concrete foundations or use ground fixing devices with a load-bearing capacity of ≥5kN/m². Some scenic spots use detachable foundations for easy restoration later.
3. Assembly and Connection: The main body produced by factory modularization is assembled by lifting and splicing. Water and electricity pipelines are connected using quick-connect methods. The installation time is usually ≤2 hours. External signs should meet nighttime visibility requirements.
4. Acceptance Criteria: According to the Tianjin Municipal "Technical Requirements for Mobile Environmental Sanitation Facilities" (DB12/T 690-2015), focus on testing airtightness, drainage system sealing, and anti-slip performance.

IV. Design and Material Adaptation to Northern Climate

1. Main Frame: Use stainless steel or thickened aluminum alloy materials to ensure no deformation at -20℃.
2. Ventilation System: Equip with windproof louvers to prevent direct blowing of cold wind and sand intrusion in winter.
3. Sanitary Fittings: Choose ceramic cartridge faucets to prevent freezing and cracking. The water seal height of the squat toilet should be ≥50mm to prevent odors. The circuit should be equipped with leakage protection devices, and sockets should be designed to be splash-proof.

V. Supplier Selection
Local suppliers in Tianjin, such as Haoshitong Pipeline Engineering (Beijing) Co., Ltd., provide installation, leasing, and sales services. There are also customized suppliers that can design personalized solutions according to urban culture and environmental characteristics.
