Bored pile with improved end bearing capacity

摘要

The present invention relates to a buried pile with improved tip support, which is provided with a tip shoe that enlarges the cross-sectional area at the tip of the pile, and forms an extension plate of the tip shoe inclined upward in the upper direction of the pile and has a stepped shape on the lower surface of the extension plate. It is to provide a buried pile with improved end support force to further increase the end area by increasing the ground area by forming a stepped portion to enlarge the cross-sectional area. The present invention for achieving the above object, in the embedded pile comprising a tip shoe which is attached to the tip of the pile body and the pile body to improve the end support force, wherein the tip shoe is attached to the tip of the pile body Tip attachment plate; A tip extension plate which is formed to extend larger than the diameter of the pile body at the edge of the tip mounting plate, and is bent upwardly inclined in the head direction of the pile body; It is a technical subject matter that includes a; protruding portion to increase the ground area on the lower surface of the tip extension plate to improve the tip support force.
