関するものである。[Detailed Description of the Invention] ゛ (Industrial Application Field) □ The present invention relates to a method for repairing concrete structures such as tunnels, and more specifically, the present invention relates to a method for repairing concrete structures such as tunnels, and more specifically, the present invention relates to a method for repairing concrete structures such as tunnels, etc. This invention relates to a method for repairing concrete parts that are at risk of falling off or where icicles are generated due to water leakage from cracks.
（従来の技術と問題点） まづ、トンネルについて説明する。(Conventional technology and problems) First, let me explain about tunnels.
トンネルをＩＩＩ築する場合の施工順序は、大別して地
山の掘削、１次覆工および２次覆工の３作業からなって
いる。The construction order when constructing a tunnel can be roughly divided into three steps: excavation of the ground, primary lining, and secondary lining.
一般に、２次覆工の現場打ちコンクリートは、１１１Ｍ
コンクリートで施工する場合が多い、その為、施工後の
年月の経過と共に２次覆工面にクラックが発生したり、
剥落の危険のある箇所が生じてくる。Generally, cast-in-place concrete for secondary lining is 111M
Construction is often done with concrete, and as a result, cracks may occur on the secondary lining surface over time after construction.
There will be areas where there is a risk of flaking.
２次覆工面にクラックが生じると、トンネルとしての安
定性が損なわれるとともに、コンクリートの剥落の危険
性の他にも、水みちができとのクラック面より漏水し、
冬季で特に寒冷地では、つららとなり交通に支障をきた
す等の問題があった。If cracks occur on the secondary lining surface, the stability of the tunnel will be compromised, and in addition to the risk of concrete spalling, water will leak from the cracked surface of the secondary lining.
In winter, especially in cold regions, icicles form and cause problems such as interfering with traffic.
また他の構造物でもクラックが発生した場合、その機能
が損なわれたり、該クラック部分に雨水等が浸入し凍結

機能が損なわれる欠点があった。In addition, if cracks occur in other structures, their functions may be impaired, and if rainwater or the like enters the cracked portion and freezes, the cracks will increase and the function of the concrete structure may be impaired.
