入部以外の被補修部にシールを施こしている。Prior Art and Problems A repair agent injection hole is drilled in the repaired part such as a crack or floating mortar part in a concrete building, or an injector is placed in the repaired part, and the above injection hole or C4L I am injecting a medicinal agent into the tank asc mr i. In order to prevent the repair agent from flowing out from the repaired part other than the injection part when the repair agent is injected, a seal is applied to the repaired part other than the injection part.
このように補修剤性入部以外の被補修部をシールして完

ないという間１点を有すると共に１上記圧縮された封入
エアのために壁に剥落の危険が生じるという問題点があ
る。If the area to be repaired other than the area where the repair agent enters is completely sealed in this way, the air in the area to be repaired will lose its escape port and remain sealed, so the sealed air will be injected with the repair agent. The compressed air prevents the repair agent from filling every nook and cranny of the repaired area, making it impossible to perform a complete repair. There is a problem that there is a risk of peeling.

補修工法の提案を目的とする。The present invention has been made in view of this problem, and utilizes the difference between the air pressure inside the repaired part of the concrete structure and the air pressure outside the concrete body to inject a repair agent.
The purpose of the present invention is to propose an excellent repair method that allows the injected repair agent to be filled into every nook and corner of the area to be repaired and to efficiently perform repairs with a good finish.
問題点解決のための手段
本発明は、上記発明の目的を達成するため、コンクリー
ト躯体に発生した被補修部の内部気圧をコンクリート躯

るという補修工法を提案する。Means for Solving Problems In order to achieve the object of the invention, the present invention forcibly lowers the internal pressure of the area to be repaired generated in the concrete structure to a lower pressure than the external pressure of the concrete structure and injects a repair agent. We propose a repair method to do so.
作用効果
本発明は、上記手段からなるので、低圧の被補修部内に
補修剤をスムースに注入しえるのみならず、その注入さ

うことができる。Effects Since the present invention comprises the above-mentioned means, it is possible not only to smoothly inject the repair agent into the low-pressure repaired area, but also to quickly fill the injected repair agent to every nook and corner. During the injection of the repair agent, the area to be repaired is pressurized with extremely high pressure, which eliminates the fear of the wall falling off.1 Therefore, it is possible to perform repairs with a clean finish that minimizes the risk of water intrusion. At the same time, repair work can be carried out efficiently.

用できる。All of these construction methods are based on the atmospheric pressure inside the repaired area (2),
Using the difference between the atmospheric pressure outside the concrete frame (1), that is, lowering the atmospheric pressure inside the area to be repaired (2), the repair agent (3) is applied.
Since the repair agent is injected, it is not only easy to inject the repair agent, but also the injected repair agent (3) can be filled into every corner of the repaired area (2). Since no high pressure is applied to the area to be repaired (2) during the injection work in (3), you can work with peace of mind without worrying about the wall falling off, and the area to be repaired (2) is significantly larger. Even if the problem occurs, if a large number of stop pulps (4) and injection valves (5) are installed in the area to be repaired (2), it becomes possible to repair the area at once, making the repair work more efficient. 1, and the repair agent (3) is filled to every corner of the repaired area (2), resulting in a clean finished repaired area. Furthermore, these construction methods can be used for repairing concrete structures (1) underwater, underground, and the like.
