Hot dip galvanized spiral ground pile outdoor anti-corrosion fixed base photovoltaic fence column support

Description :

  Spiral ground pile is a ground fixing device used to replace traditional concrete foundations, mainly solving the problems of cumbersome installation of outdoor facilities, damage to the ground surface, and long waiting time for solidification. It rotates into the soil through spiral blades, utilizing soil resistance to provide strong resistance to pulling and compression. Typical working conditions include fixing photovoltaic power station brackets, supporting outdoor fence columns, reinforcing temporary building foundations, and installing landscape lighting facilities. This product is suitable for various soil environments, can be quickly deployed and immediately bear loads, significantly shortens the construction period, reduces labor and material costs, and is the preferred solution for modern lightweight foundation engineering.

  The spiral ground pile is usually made of high-quality carbon structural steel or low-alloy high-strength steel, and the surface is hot-dip galvanized. The thickness of the zinc layer meets national standards, ensuring excellent anti-corrosion and rust prevention performance in harsh environments such as humidity, acid and alkali. The service life can reach more than 20 years. The common specifications range from 50mm to 150mm in diameter, and the length can be customized according to needs, generally between 600mm and 3000mm. The spiral blades are precision rolled and welded, with smooth edges and no burrs, reducing the resistance to screwing in. The product complies with the GB/T 13912 metal coating standard and undergoes strict torque testing and tensile testing to ensure structural integrity and connection reliability, adapting to temperature changes ranging from -40 ℃ to 80 ℃.

  When selecting, it is important to consider the soil type and bearing requirements. For soft sand or clay, it is recommended to choose products with larger blade diameters and denser pitch to increase the contact area; For hard soil layers or soil containing gravel, it is necessary to choose a type with thicker pipe walls and reinforced tips, and if necessary, use it in conjunction with pre drilling technology. If used in long-term static load scenarios such as photovoltaic brackets, the creep resistance performance should be verified; If used in scenarios such as fences that may be subjected to lateral impact, attention should be paid to the bending strength of the pile. Compared with ordinary driven piles, spiral piles do not damage the surrounding soil structure, can be disassembled and reused, and have minimal impact on surrounding vegetation, making them suitable for construction areas with high environmental requirements.

  During the installation process, verticality should be maintained, and a dedicated hydraulic motor or torque wrench should be used to rotate at a constant speed to avoid deformation or damage to the coating caused by forced tapping. Stop rotating when the predetermined depth or torque value is reached, ensuring that the top flange is level. Daily maintenance mainly checks whether the connecting bolts are loose, especially after experiencing extreme weather conditions such as strong winds and earthquakes. If slight scratches are found on the surface coating, zinc rich paint should be applied for repair in a timely manner to prevent rust from spreading. In areas with frequent freeze-thaw cycles, attention should be paid to the possible uplift force of soil frost heave on the pile body, and sufficient safe burial depth should be reserved in the design. Regularly inspect the soil settlement around the pile to ensure the stability of the foundation.
