Abstract
PURPOSE: To prevent the bad influence of side pressure on nearby structures by allowing the side pressure to escape toward inside while excavating and discharging soil by the injection pressure of grout in such a way as to reduce a dislocation applied on the surrounding ground in the improvement of soft ground.
CONSTITUTION: A screw 2 is axially provided to an injection rod 1, a stirring head 4 with a blade 3 is connected to the tip of the screw 2, and also a swivel 6 connected with a grout feed hose 5 is attached to the top of the screw 2. When a driver 3 is operated and the screw 2 is turned and excavates the ground to a given depth, a grout from the hose 5 is sent under high pressure to the rod 1 and injected horizontally to the rod 1 from a nozzle 9 at the tip of the blade 3 to form a hardened layer A. In this case, the injection pressure of the grout is allowed to escape into excavated cavity (a) to reduce the side pressure.
