PURPOSE: A top-shaped pile is provided to securely and stably connect piles from up and down, and left and right during construction by comprising four connection units on the periphery of a top unit. CONSTITUTION: A top-shaped pile comprises a top unit and a pile body unit. The top unit is formed to have a hollow shape inside and a cone shape which becomes narrower toward the lower side of the top unit. The pile body unit is extended to the lower part of the top unit to be a predetermined length. Four connection units are symmetrically installed around the top unit. The two which are not mutually faced among the four connection units include projection units (210) which are protruded in the length direction of the axis of a top, and the remaining two connection units include accommodation grooves (220) which are formed in the length direction of the axis of the top to accommodate the projection units. |
