Installation of Guard Booth Portable Toilets in Ningxia

The installation of guard booth portable toilets in Ningxia requires special attention to ground treatment, structural fixation, and climate adaptability design. The specific steps and key points are as follows:

1. Ground Foundation Treatment The ground foundation is a crucial element for ensuring the stability of the guard booth. In Ningxia, the appropriate foundation type should be selected based on site conditions.

• Concrete Pouring Foundation: Suitable for long-term fixed installations, it is essential to ensure that the ground levelness error does not exceed 5mm and to reserve a drainage slope of 3%-5% to prevent water accumulation from eroding the foundation. After pouring, the foundation should be cured for 7-14 days until the strength meets the standard before proceeding with the booth installation.
• Steel Frame Elevated Foundation: Suitable for temporary use or uneven ground (such as sandy areas or slopes), the steel frame should be made of national standard galvanized square tubes (thickness ≥ 3mm) and undergo anti-rust treatment (such as spraying epoxy zinc-rich primer) after welding. During installation, a level should be used to calibrate the steel frame plane, with an error controlled within ±2mm.

2. Structural Fixation and Wind Resistance Design The connection between the guard booth and the foundation must be secure, especially in response to the windy climate characteristics of Ningxia.

• Bolt Fixation: Use M12 or larger chemical anchors or expansion bolts, with a bolt spacing not exceeding 500mm, and pair them with anti-loosening washers to prevent vibration loosening.
• Anchor Bolt Reinforcement: In areas with wind speeds ≥ 8, the number of anchor bolts should be increased to 4-6 per square meter, and they should be embedded into the concrete foundation to a depth of ≥ 300mm.
• Steel Frame Welding Reinforcement: The connection between the steel frame foundation and the booth bottom frame should be fully welded, with a weld height ≥ 6mm. After welding, non-destructive testing should be conducted to ensure strength.

3. Climate Adaptability Design Ningxia experiences significant temperature differences between day and night (with summer differences reaching over 20°C) and cold winters (with minimum temperatures below -20°C). Therefore, it is essential to optimize the doors, windows, and insulation layers.

• Door and Window Sealing: Use thermal-break aluminum profiles (with insulation strip widths ≥ 24mm) paired with double-glazed units (5mm+12A+5mm). The airtightness rating should meet or exceed Grade 6 in the national standard GB/T 7106-2008.
• Insulation Layer Design: The walls should be filled with 100mm-thick polystyrene foam boards (density ≥ 18kg/m³) and covered with an aluminum foil reflective layer to reduce heat radiation. The roof should adopt double-layer color-coated steel sheets with 50mm glass wool in between, with a heat transfer coefficient ≤ 0.5W/(m²·K).

4. Installation Services and Manufacturer Selection Some local manufacturers in Ningxia (such as Ningxia Lifang Baisheng Ankuai Hongmen) offer one-stop installation services, including foundation construction, booth hoisting, water and electricity connection, and commissioning. When selecting a manufacturer, it is necessary to verify its qualifications (such as having a Grade III or higher professional contracting qualification for steel structure engineering), past cases, and after-sales service response time (recommended ≤ 4 hours).

Summary: The installation of guard booth portable toilets in Ningxia should be tailored to geological conditions, climate characteristics, and usage requirements. Through scientific ground treatment, secure structural connections, and efficient insulation design, the equipment can be ensured to operate stably over the long term in extreme environments.
