CHEMICAL SOLUTION INJECTION CONSTRUCTION METHOD
PROBLEM TO BE SOLVED: To provide a chemical solution injection construction method capable of injecting a predetermined amount of chemical solution while controlling an infiltration state of the chemical solution, by controlling a chemical solution injection method.SOLUTION: A chemical solution injection construction method injects chemical solution into the ground while dynamically changing injection speed of the chemical solution. The construction method includes: a process of installing an injection pipe to a target ground; and a process of injecting the chemical solution into the injection pipe while increasing/decreasing the injection speed of the chemical solution. In performing the injection, the average injection speed is reduced and increasing/decreasing amplitude is reduced when injection pressure becomes equal to or higher than a predetermined value.SELECTED DRAWING: Figure 1
【課題】薬液の注入方法を制御することによって、薬液の浸透状態を制御しながら所定の量の注入を行うことが可能な薬液注入工法を提供する。【解決手段】薬液の注入速度を動的に変化させて地盤中に注入する薬液注入工法である。そして、注入管を対象地盤に設置する工程と、注入管に対して薬液の注入速度を増減させて注入を行う工程とを備えている。ここで、注入は、注入圧力が所定値以上となったときには、平均注入速度を小さくするとともに、増減の振幅を小さくする。【選択図】図１
