摘要

PURPOSE: A stirring device for the ground improvement is provided to excavate the bedrock rapidly and to heighten efficiency of stopping water by excavating the ground for improvement to the necessary depth. CONSTITUTION: The stirring device for the ground improvement contains a solidifier supply pipe formed axially in an auger shaft(21), a stirring blade(23) installed in the middle of the auger shaft(21), a cylindrical housing unit(110) formed on the extended end of the auger shaft(21), a solidifier supply branch pipe(111) formed in the housing unit(110) and connected to the solidifier supply pipe, an air supply pipe(120) formed parallel to the solidifier supply pipe in the auger shaft(21), an excavation hammer(200) coupled to the inside of the housing unit(110) and connected to the air supply pipe(120), a feed screw(130) formed on the outside of the auger shaft(21) and the housing unit(110), an excavation wing(24) arranged to the outside of the housing unit(110), and a solidifier exhaust port(140) formed in the excavation wing(24) and connected to the solidifier supply branch pipe(111).
