What are the safety features of photovoltaic spiral piles?
Publish Time: 2024-08-27
1. Bearing capacity
High bearing capacity: The photovoltaic spiral pile is made of high-quality carbon structural steel material, which ensures the strength and stability of the product. Its unique spiral design can be directly buried in the soil through rotation, effectively transferring the weight of the upper photovoltaic module to the foundation, and has high compressive and tensile bearing capacity. According to research, when the blade spacing ratio (blade spacing/blade diameter) is 3~4, the ultimate bearing capacity of the pile reaches a better value.
Compliance with national standards: According to national standards such as the "Building Structure Load Code" and the "Steel Structure Design Code", the bearing capacity design value of the spiral pile must meet certain safety requirements. In actual applications, the compressive design value of the spiral pile can reach 10KN, and the tensile design value can reach 20KN, which can meet the requirements of the photovoltaic module for the foundation bearing capacity.
2. Stable performance
Wind pressure resistance: Photovoltaic modules are installed outdoors and need to withstand large wind loads. With its stable structure and deep burial depth, the spiral pile can effectively resist the influence of wind pressure and ensure the safe and stable operation of photovoltaic modules under severe weather conditions.
Impact and vibration resistance: spiral piles have strong impact and vibration resistance, and can provide reliable support and protection for photovoltaic modules when natural disasters such as earthquakes occur.
3. Durability
Anti-corrosion treatment: After being buried in the soil, spiral piles are susceptible to erosion by groundwater and soil chemicals. In order to improve its durability, the surface of spiral piles is usually subjected to anti-corrosion treatment such as hot-dip galvanizing to form a solid anti-corrosion layer to effectively prevent the occurrence of corrosion.
Long-life design: The durability and service life of the material are fully considered in the design of spiral piles, which can ensure stable bearing capacity and good working condition during the design life of the photovoltaic power station.
4. Construction safety
Easy installation: The installation of spiral piles does not require large-scale earthwork, and the foundation can be set up using a spiral drill. This installation method not only improves construction efficiency, but also reduces safety risks during the construction process.
Environmentally friendly: Compared with traditional concrete foundations, the installation of spiral piles has less impact on the environment, reduces the emission of pollutants such as dust and noise, and conforms to modern environmental protection concepts.
Photovoltaic spiral piles have the advantages of high bearing capacity, good stability, strong durability and high construction safety in terms of safety performance. These advantages make photovoltaic spiral piles widely used in the construction of photovoltaic power stations and have been recognized and praised by the majority of users.
