と共に、切粉が混入するとグラウト材の接着力を低下さ
せるという問題がある。By the way, when a hole 3 is drilled into the concrete 11 body 1 from the finishing material 2, chips 5 (shavings) are generated during drilling, as shown in FIG. Since the grout enters the hole and closes the communication part between the perforation 3 and the gap 4, it is not possible to reliably inject the grout into the gap 4, and there is a problem that the adhesion of the grout decreases when the chips are mixed in.
また、第６図のように、ドリルによる穿孔３の穿設時に
、仕上材２の内面側で穿孔３の開口部に欠け６が発生し
やすく、この欠けた部分が隙間４に落込み、上記と同様
の問題が発生する。In addition, as shown in FIG. 6, when drilling the hole 3 with a drill, a chip 6 tends to occur at the opening of the hole 3 on the inner surface side of the finishing material 2, and this chipped part falls into the gap 4, causing the above-mentioned A similar problem occurs.

除去する。A slit is made in the concrete building using a disc-shaped cutter so that it intersects with the crack and communicates with the gap between the floats, and an injection plug is inserted into the part of the slit that opens on the outside of the building. Install the grout and close the other parts with puncture material, or leave the injection hole and close the other part with bank material, and inject grout into the crack or floating gap from the injection plug or injection hole part through the slit. After the grout has hardened, the pack material and injection plug are peeled off and removed.

に行なえる。As described above, according to the present invention, a disc-shaped cutter is used to cut slits that communicate with the gaps caused by cracks or floats in a concrete building, and grout is injected into the gaps between the cracks or floats through the slits. By filling the slit, the chips generated when cutting into a concrete building with a cutter can be reliably discharged to the outside, preventing the chips from entering cracks and gaps, and preventing the chips from entering the cracks and gaps from the slit. Grout material can be poured reliably.
また、スリットはクラックや隙間に対して広い連通量を
確保することができ、クラックや隙間へのグラウト材の
注入が円滑に行なえる。Further, the slits can ensure a wide communication amount with respect to cracks and gaps, and the grout can be smoothly injected into the cracks and gaps.
更に、スリットの形成による切粉がクラックや隙間内に
