METHOD AND DEVICE FOR CONSTRUCTING FILLER SLAB FOR DAM CONCRETE FACING

摘要

PURPOSE:To enhance the operating easiness for a strip form by suspending it at an anchor driven at the top of a slope face, and by placing filler slab while the strip form is winched up. CONSTITUTION:An anchor 1 is driven at the top of a slope face, and a filler slab 33a 3s placed while a strip form 4 mounted horizontally on a rail 3 laid on the slope face is winched up through a wire 6. When the strip form 4 has moved to the top of the slope face, a liftup mechanism is operated to cause lifting-up from the concrete surface into which the strip form 4 is just driven, followed by separating. Then winches 5, 5 are operated so as to descend the strip form 4. When descend is completed, a transverse motion roller 11 is grounded by operating a grounding operation mechanism. In this condition, the strip form itself is moved to the filler slab placing region 33 of next execution lane.
