PURPOSE:To improve deforming ability, by a method wherein a surronding substance, having modulus of elasticity higher than that of concrete, is disposed in a direction extending about right angles with a pile axis outside reinforcing cage and in the vicinity of the outer peripheral part of a concrete pile. CONSTITUTION:A reinforcing cage 2 is interposed into a cylindrical net 3 or rings 4 arranged at given intervals, or lines 5 is wound at given intervals around the reinforcing cage 2. A surrounding substance and the reinforcing cage are disposed in forms for a pile, and concrete is placed by centrifugal molding. |
