Spiral ground pile is a kind of ground bored pile with spiral characteristics, including drill bit/drill pipe/spiral blade and connecting pipe, and the drill pipe is associated with the power input connector. It is convenient to drive the pile into the ground and use it directly as the pile body. The spiral ground pile can penetrate and compact the soil around the pile hole, which improves the side friction resistance of the soil around the pile so that the pile foundation has the strong bearing capacity, pullout resistance, horizontal resistance, small deformation, and good stability.

Scope of application:


1. In-line spiral ground piles are used for gardens or grass.


2. In-line spiral ground piles should be suitable for soft soil or sandy ground.


3. Large in-line spiral ground piles are used in solar photovoltaic projects.


4. U-shaped spiral ground piles are applied to fences and fences.


5. Spiral piles are used to fix tents, mobile homes, greenhouses, flagpoles, guardrails, fences, etc. And it can be used repeatedly for a long time.
