REINFORCEMENT CONSTRUCTION METHOD OF CAISSON TYPE PILE, AND REINFORCEMENT UNIT BODY FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To construct a reinforcement assembly that requires time, as a reinforcement unit body on the ground to attain safe and easy assembly while shortening a construction period.;SOLUTION: A reinforcement construction method for constructing the reinforcement assembly in a caisson type shaft comprises: connecting hoops annularly and arranging shear reinforcing bars radially in grated shape at the hoops to form a reinforcement block body, and supporting a plurality of stages of the reinforcement block bodies by ladder reinforcements to form and arrange the reinforcement unit body 1; transferring and lowering the reinforcement unit body 1 along guide bodies and binding or welding the reinforcement unit body 1 to the guide bodies; carrying out superimposed fixing to the respective ladder reinforcements of the reinforcement unit body 1 by the transfer and constructing a working scaffolding in sequence by following; arranging vertical main reinforcements after the reinforcement unit body 1 is constructed in the caisson type shaft; and binding or welding the vertical main reinforcements to the reinforcement unit body 1 to construct the reinforcement assembly. The reinforcement unit body 1 is transferred by a suspension support body 3 with a transfer tool body having support fittings for supporting the reinforcements, disposed at a hanging frame body 3a.;COPYRIGHT: (C)2010,JPO&INPIT
