CONSTRUCTION METHOD OF CONCRETE WATER CUT-OFF STRUCTURE WITH JOINT, AND CUT-OFF PLATE FIXTURE USED WITH THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a construction method of a concrete water cut-off structure with a joint and a cut-off plate fixture used with the method that enable a cut-off plate and a joint plate to be assembled and fixed readily and reliably at a site, to replace a conventional technology that lacks a simple and effective technique for directly assembling the cut-off plate and the joint plate.;SOLUTION: In a construction method of a concrete water cut-off structure with a joint, a multistory structure comprising a joint plate and a cut-off plate is assembled in the following steps for: forming a cut-off plate fixture by cutting a short square cylinder into an unequal-sided angle member and an unequal-sided channel member; using the cut-off plate fixture, erecting and fixing the two unequal-sided channel members on a foundation ground, and sandwiching the joint plate therebetween; mounting the cut-off plate thereon; laying out the two unequal-sided angle members on the cut-off plate, in plane symmetry leaving a gap at a position corresponding to an upper horizontal wall part of the unequal-sided channel member; sandwiching the cut-off plate between the unequal-sided angle member and the unequal-sided channel member; and sandwiching and fixing the joint plate in a second tier in a gap between the two unequal-sided angle members.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
