REINFORCING BAR CAGE CONNECTING METHOD FOR UNDERGROUND CONTINUOUS WALL

PURPOSE:To prevent adhesion cleavage rupture by connecting the tip of the reinforcing bar cage of a succeeding element to the reinforcing bar cage end of a preceding element with lap joints, and arranging horizontal reinforcing materials between reinforcing bars of the lap joints. CONSTITUTION:Middles of reinforcing materials 11 crossing the horizontal bars 7a are rotatably coupled with the right and left horizontal bars 7a at the tip of the reinforcing bar cage 8 of a succeeding element via long holes 12. End sections of the reinforcing materials 11 are pivotally fitted between the horizontal bars 7a, 7a, pivotal fitting sections are connected with a vertically moving operation rod 15 and a link system 17, and the reinforcing materials 11, 11 are folded into a horizontal dog-leg shape when the reinforcing bar cage 8 of the succeeding element is arranged. The reinforcing materials 11, 11 are spread into a straight line by the operation rod 15 after the reinforcing bar cage 8 is arranged, and the tips of the reinforcing materials 11 are protruded to the outside of the horizontal bars of the reinforcing bar cage of a preceding element.
