PROBLEM TO BE SOLVED: To provide a cutoff weir member for obtaining a cutoff weir having high stability by easily temporarily providing and removing the cutoff weir in a part preventing leakage of rainwater in an opening part or the like formed on a concrete slab.;SOLUTION: The cutoff weir member 1 for temporarily providing the cutoff weir 7 on the concrete slab 5 comprises a cutoff member 2 having imperviousness, a packing 3 provided on the lower face of the cutoff member 2 and interposed between the cutoff member 2 and a slab surface, and a fixture 4 driven into the concrete slab 5 and fixing the cutoff member 2 on the slab surface. The cutoff weir member 1 arranges the cutoff material 2 on the concrete slab of a part preventing leakage of rainwater so as to contact the packing 3 on the slab surface, drives the fixture 4 into the concrete slab 5, and fixes the cutoff member 2 on the slab surface so as to compress the packing 3 between the cutoff member 2 and the slab surface.;COPYRIGHT: (C)2005,JPO&NCIPI
