-
The main pole diameter can be 32-325mm, and the common wall thickness is 2.0-8.0mm.
-
60-89 type is commonly used for greenhouses, and 76-114 type is mostly adopted for photovoltaic projects.
-
Utilizing the mechanical advantage of spiral blades, the spiral pile is pressed into the soil by rotation, providing stable support relying on the friction between soil and blades as well as the pile bearing capacity.
-
No tedious steps such as ground leveling, waste soil treatment and excavation are required; only positioning and piling are needed, which can greatly shorten the construction period and save material and labor costs.
-
It can adapt to various geological conditions, such as clay, gobi deserts, gravel land, etc., and can be constructed under most climate conditions, such as rainy, snowy and freezing weather.
-
It can be recycled without polluting the environment, with simple and quick migration and zero cleaning cost.
-
Spiral piles are widely used in solar photovoltaic, wind energy, construction and other fields, such as the foundation construction of photovoltaic power stations, fruit and vegetable greenhouses, wooden houses and villas, guardrails and fences, advertising and transportation facilities, boardwalks, etc.
-
Generally, spiral piles can be used for 20-30 years; their specific service life is affected by factors such as the acidity and alkalinity of the soil and the correctness of the operation process.
