What conditions should the screw pile meet

　　Like other pile foundations, the design of embedded cement steel pile and spiral pile should also meet the reasonable and economic requirements. For the ground pile and bearing surface, it should have enough strength, rigidity and durability; for the foundation, it should not only have enough bearing capacity and not produce excessive deformation, but also consider that the ultimate bearing capacity of spiral ground pile relative to the foundation damage is very high. The primary problem of most photovoltaic ground piles is to control the settlement. Generally speaking, the settlement of spiral pile is mainly the initial settlement, which is fast and stable.
