題がある。The circular hole 3 is provided in the concrete structure 1.
Also on the surface side of, because it is in communication with the crack 2, when the adhesive is injected, it tends to flow in the direction with less penetration resistance,
A large amount of the adhesive flows into the opening of the surface of the crack 2 to apply pressure to the sealing material 6 to cause breakage.
However, there is a problem that the adhesive cannot be injected to a deep part.

できない場合が生じるという問題がある。Next, in the latter injection method, since the pipe-shaped injection tool 4 is inserted into the injection hole 7, air is trapped in the injection hole 7 when the adhesive is injected, so that the injection of the adhesive is smooth. In addition to the small diameter injection hole 7
When drilling a hole, the generated cutting chips enter the crack, clogging occurs in a portion communicating with the injection hole 7 of the crack 2, and there is a case where the press-fitted adhesive cannot be injected into the crack 2. There is a problem.
