水させるものである。(Prior art) A conventional method for preventing water intrusion and leakage from cracks in concrete buildings is to cut out the cracked concrete surface in a V-shape, insert a resin injection pipe into the V-shaped cutout, and insert a resin injection pipe above the crack. Fix the resin injection pipe to the concrete wall by pouring quick-setting mortar to bury the resin injection pipe. After that, an injection nozzle is attached to the resin injection pipe and urethane foam resin is injected, and the injected urethane foam resin comes into contact with water and foams, entering the deep parts of the cracks and branch cracks and hardening the adhesive. This will stop the water from flowing.

の止水方法にある。 The gist of the present invention is to provide a water stop agent inlet and a discharge port in a box body in which a part of the periphery is recessed into the same outer periphery shape as a part of the other periphery and has a large bottom opening, and a seal is provided on the periphery. A large number of water sealing boxes with a surrounding structure were prepared, and the boxes were placed on the concrete surface so as to close the cracks on the surface of the concrete structure, and these were fixed with anchor bolts. The outer periphery of the next water sealing agent sealing box is fitted into the recessed part of the water sealing agent sealing box so as to effectively close the next crack, and in this state, the anchor bolt is used to fix the box to the concrete wall surface. This process is repeated along the crack line to secure a large number of water sealing boxes to the concrete wall in succession, and then foamed resin, adhesive resin, etc. By press-fitting the water-stopping agent, blocking the discharge port, and filling the water-stopping agent sealing box with the water-stopping agent, the water-stopping agent is injected deep into the crack and around it. A method of stopping water from cracks in a concrete structure, which is characterized by preventing water leakage and infiltration by curing the adhesive.

1, the foamed resin is press-fitted from the water sealing agent injection pipe 7 of the water sealing agent sealing box 2. Water and air inside the water sealing agent sealing box 2 are discharged from the discharge pipe 8 by the press-fitted foamed resin 13. When the water and air are sufficiently discharged and the foamed resin 13 fills the interior space of the water sealing agent sealing box 2, the valve of the discharge pipe 8 is closed. Then, the foamed resin 13 press-fitted from the water sealing agent injection pipe 7 is sealed on the outside, the pressure increases, and it is forced into the crack 12 with strong pressure.
The foamed resin is introduced deep into the crack 12 and into the branching parts. After injecting enough foamed resin,
Close the valve of the water stop agent injection pipe 7. By performing this press-fitting of the foamed resin into the entire water sealing agent sealing box 2, the foamed resin is injected into the deep part, periphery, and branching parts of the crack along the crack line, and hardens the adhesive with the concrete wall surface. This fills the cracks and prevents water leakage and infiltration.
