  • Consolidation Of Soil By Introduction Of Solidifying Substances Into Soil (AREA)

Abstract

PURPOSE: To obtain improved performance characteristic as well as to miniaturize the apparatus by making a plurality of liftable ejection pipes being disposed around the hollow rod expand automatically while pulling up the rod.
CONSTITUTION: Hollow rod 1 is lowered into the ground until it reaches the stabilized base by the self weight of rod and giving vibration driven by the vibrator 5, etc., and while the rod is being pulled up, the liftable ejection pipes 2 is expanded and the rod is rotated, ejecting soil stabilizing agent from the nozzles 3 of the ejection pipes being supplied from high pressure pipe 6. Accordingly, soft soil around the hollow rod is solidified in column shape. At this time, because vibrator 7 being installed at the tip of the hollow rod 1 is in action, formation of solidified ground of larger diameter is surely performed. On account of the above constitution, miniaturization of the whole apparatus is feasible and its performance efficiency is enhanced.
