Abstract

막힘을 방지하여 주입량과 배니량의 최적제어를 가능하게 한 지반개량공법을 제공한다.It provides a ground improvement method that prevents clogging and enables optimal control of the injection amount and the vat amount.

지중에서 주입로드로부터 경화제용액을 분사하면서, 주립로드를 회전시키며 후퇴시킴으로써, 경화제를 지중에 주입하는 지반개량공법에 있어서, 경화제의 주입과정에서 지중내압에 따라 진공흡인장치에 의해 경화제의 주입부근방의 위치로부터 배출경로를 통해 배니를 흡출한다. 배출경로가 막힌 때에는, 주입로드의 선단측을 향하여 배출경로내에 압력수를 송출하거나, 혹은 진공흡인장치의 출력을 반전시켜 진공흡인장치에 의해 주입로드의 선단측을 향하여 배출경로내에 압력에어를 송출한다.In the ground improvement method of injecting a hardening | curing agent in the ground by rotating and retracting a state rod while spraying hardening | curing agent solution from an injection rod in the ground, in the process of injecting a hardening | curing agent by the vacuum suction apparatus according to underground pressure, Aspirate the vanes from the location through the discharge path. When the discharge path is blocked, the pressure water is discharged in the discharge path toward the distal end of the injection rod, or the output of the vacuum suction device is inverted to discharge the pressure air in the discharge path toward the distal end of the injection rod by the vacuum suction device. do.
