HOSE FOR GROUTING WATER CUT-OFF MATERIAL AND METHOD OF GROUTING WATER CUT-OFF MATERIAL TO CONCRETE PLACING JOINT SECTION

摘要

PROBLEM TO BE SOLVED: To provide a hose for grouting a water cut-off material and a method of grouting a water cut-off material to a concrete placing joint section capable of surely and suitably grouting the water cut-off material to the concrete placing joint section by surely preventing a flow passage from being closed due to the inflow of a bleeding water or slag produced when concrete is placed.;SOLUTION: This hose A for grouting a water cut-off material is used to cut off water at the placing joint section T of a concrete. The hose comprises tube members 1 having through-holes 1c extending therethrough from the inner surface 1a to the outer surface 1b, respectively; a base member 2 which has a through part 2c extending therethrough from the inner surface 2a to the outer surface 2b, which covers the outer peripheries of the tube members 1, 1, and which integrally holds the tube members 1, 1 in the state of being bound parallel to each other, and a biodegradable member 3 so installed on the outer surface 2b of the base member 2 as to cover the through part 2c of the base member 2.;COPYRIGHT: (C)2009,JPO&INPIT
