METHOD AND DEVICE FOR DETECTING STATE OF CHEMICAL INJECTION, METHOD AND DEVICE FOR CHEMICAL INJECTION, AND OUTER TUBE FOR MEASUREMENT AND INJECTION
To provide a method and device for detecting the state of chemical injection, a method and device for chemical injection for suppressing the development of cleavage injection, and an outer tube for measurement and injection that can be used in these methods and devices that can grasp the injection state during chemical injection underground in the chemical injection method and reliably detect cleavage injection.SOLUTION: In this method for detecting the state of chemical injection, an outer tube for injection 21 having a plurality of injection parts 22 is placed at a predetermined position in the ground. In order to detect the state of the chemical liquid injection while the chemical liquid is being injected into the ground from the injection part, the outer tube for measurement and injection has the plurality of injection parts 22 and a measurement port 32. At least one of a water pressure gauge, a pH meter, a thermometer, and a ground deformation measurement unit is provided near the measurement port. At least one of water pressure, pH, water temperature, and ground deformation at another predetermined location is measured by the outer tube for measurement and injection placed at another predetermined location adjacent to the predetermined location. Based on the measurement results, the injection state of the chemical solution is ascertained and it is determined whether or not it is a cleavage injection.SELECTED DRAWING: Figure 2
【課題】薬液注入工法において地中での薬液注入中の注入状態を把握し、割裂注入を確実に検知可能である薬液注入状態検知方法および装置、割裂注入の発達を抑制するための薬液注入方法および装置、ならびにこれらの方法・装置に使用可能な計測兼用注入外管を提供する。【解決手段】この薬液注入状態検知方法は、複数の注入部２２を有する注入外管２１を地盤内の所定位置に配置し、注入部から地盤内に薬液注入が行われている間に薬液注入の状態を検知するために計測兼用注入外管は、複数の注入部２２と計測口３２とを有し、計測口の近傍に水圧計、pH計、温度計および地盤の変状の計測部の少なくともいずれか１つを備え、所定位置に近接する別の所定位置に配置された計測兼用注入外管により別の所定位置における水圧、pH，水温および地盤の変状の内の少なくとも１つの計測を行い、その計測結果に基づいて薬液の注入状態を把握し割裂注入であるか否かを判断する。【選択図】図２
