ある。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a method for repairing concrete structures.
従来の技術
最近コンクリート構造物の亀裂および隙間（以下亀裂等
という。）が大きな問題になってきている。亀裂等の原
因としては骨材によるもの海砂によるものとがあると云
われているが。BACKGROUND OF THE INVENTION Recently, cracks and gaps (hereinafter referred to as cracks, etc.) in concrete structures have become a major problem. It is said that cracks are caused by aggregate or sea sand.
いずれにしても山砂利、海砂を使用したコンクリート構
造物が大量に作られている。In any case, a large amount of concrete structures are being constructed using mountain gravel and sea sand.
これらのコンクリート構造物に亀裂等が発生することに
なると大変な補修作業が必要になってくることが予測さ
れる。If cracks or the like occur in these concrete structures, it is predicted that extensive repair work will be required.
コンクリート構造物の亀裂等（ひび割れ］は。Cracks in concrete structures.
内部を確かめることができないため亀裂等内部へ確実に
充填物を充填することが非常に難かしく、また充填がで
き友かどうかの保証はできない問題点がある。Since it is not possible to check the inside, it is very difficult to reliably fill the inside of cracks, etc., and there is also the problem that it cannot be guaranteed whether the filling is successful or not.
従来の充填物の注入工法は大きく分けて、高圧高速短時
間注入法と低圧低速長時間注入法の２通シであった。Conventional filling injection methods can be broadly divided into two methods: high-pressure, high-speed, short-time injection and low-pressure, low-speed, long-time injection.
発明が解決しようとする問題点

たって注入液を注入し、従来の充填物の注入法の欠点で
あった亀裂等の入口附近の浅い箇所で充填物である注入
液が拡散し確実な注入ができないこと。The present invention has been made in view of the above circumstances, and its purpose is to create a predetermined negative pressure in cracks, etc. of a concrete structure, and inject injection liquid as a filler into the cracks, etc. In this way, the injection liquid is reliably injected over the entire crack, etc. in a short period of time, and the injection liquid, which is the filler, is diffused in shallow places near the entrance of the crack, etc., which was a drawback of the conventional filling injection method. Failure to ensure reliable injection.
その注入に熟練を必要とじ作業性が悪くコスト高になる
ことを解消することにある。The purpose of this method is to solve the problem that injection requires skill, resulting in poor workability and high cost.
