Shuzizi, also known as tree grates or tree covers, has become a common feature in many developed countries. It is widely used in road construction, park landscaping, and other infrastructure projects. However, many domestic customers are still unfamiliar with this product, which often causes confusion when making purchases. In this article, we will provide a brief introduction to the key aspects of Shuzizi to help you better understand its features and applications.
1. **Material Requirements**: The main material used for Shuzizi is ductile iron QT500-7, which must meet the national standard GB1348. This ensures high strength and durability.
2. **Maintenance and Longevity**: To ensure long-term performance, regular maintenance is essential. Especially for newly installed units, careful management is crucial. Proper care not only maintains the product’s appearance but also extends its lifespan.
3. **Quality Standards**: The surface of the Shuzizi should be smooth and seamlessly integrated with the supporting structure. Any cracks, cold shuts, shrinkage, or other defects that may affect performance are not acceptable and cannot be repaired.
4. **Design and Load Capacity**: Shuzizi comes in various styles, and the choice depends on the design requirements. The load capacity of the product should be no less than 140KN to support heavy traffic.
5. **Installation and Corrosion Protection**: The rafters and manholes can be connected using pins or other methods. The turning angle of the rafters should be at least 120 degrees. For corrosion protection, a layer of asphalt varnish is typically applied.
6. **Identification and Documentation**: Each Shuzizi should have clear markings, including the bearing grade, production date, and other necessary information. Alongside, it should come with technical documents such as a factory certificate and test report.
7. **Post-Installation Issues**: After installation, continuous vehicle traffic can cause some Shuzizi to crack or collapse over time, especially in high-traffic areas. If this happens, first check the foundation. If it's unstable, reinforcement is required. A layer of cement can be applied to the surface for additional support. Sprinkling salt around the area helps strengthen the bond between the cement and the Shuzizi, preventing it from loosening or falling off.
Understanding these details about Shuzizi can greatly assist in your future purchasing and installation decisions. Whether you're involved in urban planning, landscape design, or infrastructure development, knowing the right specifications and maintenance practices will ensure the product performs well and lasts longer.
