To provide a landslide prevention pile and a construction method for the same capable of reliably stabilizing the ground while enhancing a landscape at a low cost.
In the ground 10, a landslide prevention pile 1 is buried through a mobile layer 11 at a superficial side of a sliding plane 5 as a boundary down to an immobile layer 12 at a lower layer side thereof. The landslide prevention pile 1 comprises: an anchor section 21 and a bearing section 26 which are made of steel pipes with an axial line P1 as a center; a first blade section 22 which is installed on a periphery 21c of the anchor section 21, helical in shape with the axial line P1 as the center and positioned in the immobile layer 12; and a second blade section 28 which is installed on the periphery 26c of the bearing section 26, helical in shape with the axial line P1 as the center and positioned in the mobile layer 11.
