EXTENDED PILE

摘要

PURPOSE: An extended pile is provided to be efficiently inserted into a borehole and to improve structural stability. CONSTITUTION: An extended pile comprises a main body(100) and an extended part(200). The extended part is formed on the front end of the main body. The width of the extended part is bigger than the width of the main body. Multiple opened grooves(210) having a semi-circular cross section are formed on the edge of the extended part in a radial direction and are radially symmetrical to each other.
