LEAKAGE PREVENTING SEAL MATERIAL FOR CONCRETE STRUCTURE AND LEAKAGE PREVENTING METHOD USING LEAKAGE PREVENTING SEAL MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a leakage preventing seal material which prevents the seal material from dropping from a joint part during application, easily achieving construction work at low cost with a reduced construction period; and a leakage preventing method using the leakage preventing seal material.;SOLUTION: A joint part 18 is formed at the seam of concrete structures 17 and 17. The both wall surface parts 17a and 17a thereof are oppositely arranged. A leakage preventing seal material 19 matched to the outer shape of the joint part 18 includes a clog-like shaped cylindrical part 19A having an upper wall surface part 19a and a sponge part 19B which is inserted inside the clog-like shaped cylindrical part 19A and has an approximately vertically long rectangular cross-sectional hole 19f. The leakage preventing seal material 19 has a long shape in the axial direction, having an approximately rectangular cross section. The structure of the leakage preventing seal material 19 allows for easy insertion into the joint part 18.;COPYRIGHT: (C)2013,JPO&INPIT
