Large. Spiral ground piles are tubular piles or column piles made of metal or non-metallic materials with spiral blades. Among them, the spiral pile has high torsion resistance. The ground pile can penetrate and compact the soil around the pile hole, which improves the lateral friction resistance of the soil around the pile and gives the pile foundation strong bearing capacity and pull-out resistance. , and level. Strength, small deformation and good stability.
Hot galvanize the surface of the spiral pile. Corrosion of spiral piles when soaked in water is electrochemical corrosion. Hot-dip galvanizing on the surface of spiral piles can effectively reduce the electrochemical reaction between spiral piles and water. Therefore, if the spiral piles corrode in water, the surface of the spiral piles corrodes. spiral ground piles must be galhot vanified. Spiral ground piles have the advantages of convenient construction, rapid progress and low environmental impact, and have been gradually popularized and used in photovoltaic ground supporting foundations.
