CONTINUOUS DRIVING METHOD FOR FLEXIBLE ISOLATION PLATE

摘要

PROBLEM TO BE SOLVED: To provide a continuous driving method for flexible isolation plates preventing the joint sections of the flexible isolation plates from being slipped from each other. SOLUTION: Penetration frames 21 and 22 having frame joint sections on both end sides are prepared, the flexible isolation plates 1 having isolation plate joint sections on both end sides put on the penetration frames are prepared, and a process lowering one penetration frame 21 putting on the flexible isolation plate 1 in the ground G and a process locking an isolation plate joint section on one end side of the flexible isolation plate 1 put on the other penetration frame 22 with a joint section on the other end side of the flexible isolation plate 1 put on one penetration frame 21 and only pulling out one penetration frame 21 on the ground after the other penetration frame 22 is lowered in the ground in a state to lock the frame joint section on one end side of the other penetration frame 22 with the frame joint section on one end side of one penetration frame 21 are successively repeated to form a continuous wall in the ground by a plurality of flexible isolation plates 1.
