Description
このグラウト注入には、トンネルが地表から浅い個所では地上から注入管を挿入して行うこともできるが、地下深くでは地上からのグラウト注入を行うことができない。 This grouting is tunnel can be performed by inserting an injection tube from the ground at a shallow point from the surface, a deep underground can not be performed grouting from the ground.
この先進導坑２内から直線状の注入管１０を、縦中心線ＣＬを挟む両側の前記本トンネル１断面上方領域にそれぞれ挿入する。この注入管１０の挿入に際しては、ケーシング掘り形式の場合には、ケーシング掘りし、その中に注入管１０を挿入した後、ケーシングを引き抜く。ロッド注入を行う場合には、そのロッドにより削孔して、そのロッドを注入管とすることができる。先進導坑２内から注入管１０を挿入するために、小型の削孔機を選択して先進導坑２内に持ち込めばよい。 A linear injection pipe 10 is inserted from the inside of the advanced tunnel 2 into the region above the cross section of the main tunnel 1 on both sides of the vertical center line CL. When inserting the injection pipe 10, in the case of the casing digging type, the casing is dug, the injection pipe 10 is inserted into the casing, and then the casing is pulled out. When injecting a rod, a hole can be drilled by the rod and the rod can be used as an injection pipe. In order to insert the injection pipe 10 from inside the advanced shaft 2, a small drilling machine may be selected and brought into the advanced shaft 2.
本発明において、注入方式および注入管形式、あるいはグラウト材料について限定されるものではない。 In the present invention, injection method and the injection pipe form it is not intended to be limited constant or with a grout material.
