に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for repairing a wall surface capable of effectively injecting a repair material into a crack generated in a concrete structure such as a building or a sewer, a breakwater, a sabo dam, a pier, and the like.

る。2. Description of the Related Art In recent years, cracks have occurred in the above-mentioned various concrete buildings, such as aging buildings constructed 20 to 30 years ago, causing various problems.
For example, if a crack on the wall is left as it is, acid rainwater will enter the inside of the crack and corrode the reinforcing steel, thereby accelerating the aging of concrete structures and causing partial collapse of concrete. Therefore, the manager of the aging concrete building needs to carry out the repair work on a regular basis.

いという結果をもたらしていた。[0003] In the maintenance of such a concrete building, it is important that (a) it is confirmed that the wall-injection repair material is injected into every corner of the crack, and that the crack is surely closed. (B) that the moisture present inside the crack does not hinder the hardening / adhesion effect of the wall-injected repair material, (c) that it can reliably fill even micro cracks branched inside, (d) ) It is required that the penetration of water into the cracked part after the repair is approximately the same as that of the part without cracks. However, with the conventional maintenance method, the filling of the wall-injected repair material is possible to some extent for large or medium cracks, but the filling of the wall-injected repair material tends to be insufficient for small to fine cracks. . In addition, when water is present in the crack, the adhesion and obstruction of the wall-injected repair material is hindered, and insufficient filling of such small to fine cracks cannot completely prevent rainwater intrusion. The effect of the repair was only limited.

りにくい事などがその原因として考えられる。[0004] The insufficient filling and hardening of the repair material for wall injection in the above-mentioned micro-cracks is presumed to be due to the following effects according to the studies of the inventors. (a)
There are various types of wall-injected repair materials, but when they are injected from small to fine cracks, the surface tension of the wall-injected repair material makes it difficult for the wall-injected repair material to penetrate into the microcracks. (B) In addition, hardening or adhesion inhibition of the wall-injected repair material due to the presence of moisture in the crack, (c)
It is considered that the reason is that the component of the wall-injection repair material has a large particle size and is hard to enter into a fine crack.

As (J), various types such as inorganic or organic type, one-pack type or two-pack type are used, but here, "It can be injected into micro cracks branching into concrete" Even when water is present, the filled wall-injection repair material (J) forms a dense hardened body so that cracks can be completely closed and re-integrated. '' It is easy to judge and it is possible to inject large quantities with pumps and guns etc. "
The penetration of water into the repaired crack should be about the same as that of the crack-free part '', which is a specification required for a wall-injected repair material (J). A slurry of hydraulic filler using ultra-fine blast furnace slag cement is used. Hereinafter, the ultrafine blast furnace slag cement will be described as a typical example.

なる。The vibration is transmitted to the wall-injected repair material (J) as vibration in the injection direction, and is transmitted to the entire wall-injected repair material (J) during injection. As shown in Fig. 6 (e), the vibration in the injection direction transmitted to the tip of the wall injection repair material (J) penetrating the micro crack (h) destroys the surface tension generated on the surface. And make it easier to proceed. In addition, due to the presence of water injected prior to the injection of the wall injection repair material (J), the ultrafine blast furnace slag cement slurry does not absorb its moisture by the surrounding cracks (h), and therefore, its viscosity is increased It will invade without. When the crack (h) is penetrable, the wall-injected repair material (J) injected from one repair member (40)
Will flow out of the other repairing member (40), and the amount of the outflow is measured, and the actual amount of the injected slurry can be calculated by subtracting the amount from the injected amount. The actual filling amount also deducts the water content.
