摘要： PROBLEM TO BE SOLVED: To provide a resin penetrated hose for preventing a paste concrete liberated part, which is generated in jointing new concrete, from intruding, and achieving high cut-off performance at a placing joint part of a concrete member.
SOLUTION: The resin penetrated hose 1 comprises a tubular body 2 with a communicating hole equally formed for communicating a hollow part and an outside, a bundle material 3 bundling the plurality of the tubular bodies 2 in parallel, a glass cloth 4 formed by winding the bundle material 3 in a plurality of layers, and a band shaped nonwoven cloth 5 equally arranged in an extending direction of the tubular body 2 on a parallel arrangement surface side of the tubular body 2 on an outer circumferential surface of the glass cloth 4. The resin penetrated hose 1 is provided with an injection tube for injecting resin for injection 7 and water on one end, and an exhaust tube for exhausting the resin for injection 7 and water passing the tubular body 2 on the other end. The water and the resin for injection 7 are supplied in sequence in a clearance generated in the placing joint part of the concrete member by pressing the water and the resin for injection 7 in sequence in the tubular body 2 through the injection tube, and they react each other to foam and expand, and the cut-off structure is formed.

摘要： PROBLEM TO BE SOLVED: To provide a high-pressure injection water cutoff method and a water cutoff material, which enable appropriate cutoff by establishing required performance, that is, injection filling properties, cutoff adhesive properties and durability, even for a water leakage crack such as a cracked part of a concrete structure and a placing joint part thereof.
SOLUTION: In this high-pressure injection cutoff method, a cutoff material injecting hole 2 is drilled in the water leakage crack 3 of a concrete wall 1 at a prescribed angle with respect to a concrete surface layer, so that a hermetically sealed chamber 5 for retaining the cutoff material 4 can be formed while crossing the crack 3; next, the crack 3 of the concrete surface layer is sealed with quick-setting cement 8 and an injection plug 7 with a non-return valve is fitted into the hole 2; after that, the cutoff material 4, which is mainly composed of a hydrophilic one-component polyurethane prepolymer, is pressure-injected from the injection plug so as to be infilled into the hermetically sealed chamber and the water leakage crack in prescribed quantities; and the cutoff material is made to permeate into the water leakage crack while being foamed by chemical reaction with infiltrating water.
