ABSTRACT:
All-around type ground reinforcing and consolidating method comprises an excavating step for forming an excavated space in a predetermined area in the ground by using a dual excavating rod composed of an outer excavating member and an inner excavating member which is movably arranged in the outer excavating member; a retracting step for retracting the inner excavating member from the outer excavating member, whereby the outer excavating member is remained in the excavated space; a check step for checking the excavated space by inserting a light member containing a battery into the excavated space; an inserting-step for inserting an injection rod into the outer excavating member; a pressure adjusting step for adjusting the pressure in the excavated space; and an injecting step for injecting a hardening material into the excavated space with retracting the outer excavating member and the injection rod, whereby the predetermined area can be consolidated. An apparatus adapted for the above method comprises a dual excavating rod, an injection rod, and a drive unit for selectively driving the dual excavating rod and the injection rod linearly and revolvingly. The dual excavating rod includes and outer excavating member and an inner excavating member which is movably inserted in the outer excavating member.
