Abstract (en)
A water expansion cut-off plate of the invention is one embedded in a concrete placing joint. A tubular grout material injection portion is provided to extend from one end surface in the longitudinal direction of the water expansion cut-off plate to the other end surface thereof, and a grout material discharge portion is provided for discharging a grout material, which has been injected into the grout material injection portion, into a gap between the water expansion cut-off plate and concrete. The grout material discharge portion is expanded by an injection pressure of that grout material which is injected into the grout material injection portion. Thus it is possible to adequately perform cut-off without posing a structural strength problem even when a gap is produced at a concrete placing joint, in particular, that concrete placing joint which is poured in a reverse manner. <IMAGE>
