<p><P>PROBLEM TO BE SOLVED: To provide an underground structure which is formed by connecting a core material in an earth retaining wall with a RC skeleton and which can perform exposure work of a core material simply and quickly. <P>SOLUTION: An underground structure is formed by connecting a core material 1 in an earth retaining wall W with a RC skeleton S, and the core material 1 is provided with a skeleton side flange 11 having a reinforcement insertion hole, a natural ground side flange 12 facing the skeleton side flange 11, a reinforcement for core material 2 fixed to the natural ground side flange 12 and a coupler for mechanical joint 3 fitted to the reinforcement for core material 2. The coupler 3 is arranged between the skeleton side flange 11 and the natural ground side flange 12, and the RC skeleton S has an anchoring reinforcement 4 reaching the core material 1, and the anchoring reinforcement 4 is connected with the coupler 3 through the reinforcement insertion hole. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
