Helical piles are an innovative deep foundation type being used for decades across Canada. They have various advantages over conventional smooth-shaft piles. They are installed as single piles or groups to resist loads in axial and lateral directions. In recent years, helical pile groups have been increasingly popular due to the increasing demand on deep foundation capacity.

螺旋桩是一种创新的深基础类型，在加拿大各地使用了几十年。与传统的光桩相比，它具有许多优点。它们被安装为单桩或群桩，以抵抗轴向和横向方向的荷载。近年来，由于对深基础承载力的要求越来越高，螺旋群桩越来越受到人们的青睐。
