PURPOSE: A pile with an extended head is provided to reduce construction time and costs by enabling the insertion work of the pile even in a narrow borehole. CONSTITUTION: A pile with an extended head comprises a pile body(100), an intermediate member(200), multiple extension members(300), a longitudinal guide unit(400), a center member(500), and an extension plate(600). The pile body is buried in the ground. The intermediate member is coupled to the bottom end of the pile body. The extension members are extendible outward from the intermediate member in a radial direction. The longitudinal guide unit guides the radial extension of the extension members. When the center member touches the bottom surface of a borehole, the center member pushes the inner ends of the extension members outward. The extension plate comprises an extension plate forming member(610) and extension plate border members(620). The extension plate forming member is installed on the bottom surface of the center member. The extension plate border members are formed on the bottom edges of the extension members. |
