PURPOSE: A pile with an extended head is provided to enable stable construction by preventing an extension member from touching the inner surface of a borehole. CONSTITUTION: A pile with an extended head comprises a pile body(100), an intermediate member(200), multiple extension members(300), a vertical guide(400), a center member(500), a stopper member(700), and a downward movement restriction member(600). The pile body is buried in the ground. The intermediate member is coupled to the bottom end of the main body and has a stopper member through hole(220). The extension members are extendable from the intermediate member. The vertical guide couples the extension members to the intermediate member and guides the extension of the extension members. The center member extends the extension members outward. The stopper member is formed on the top of the center member and has a head portion(710). The downward movement restriction member restricts the downward movement of the stopper member. |
