Abstract

PURPOSE: To eliminate poor mixing or non-equality of mixing by sending back and filling excavated soil which is improved by mixing the excavated soil to be removed on the ground as an auger is pulled up with improving materials through a hollow shaft of the auger.
CONSTITUTION: First, an earth auger 1 is penetrated to a specified depth of the poor soil (a). Then, the earth auger 1 is gradually pulled up on the ground while rotating according to requirement, and two operation-works are carried out at a time as the auger is pulled out. One operation-work is such that excavated soil (b) to be removed to the inside of a storage tank 5 is sent to a mixing tank 8 through a transfer line by operating a pressure pump 6, and that it is mixed with improving materials such as cement, lime and others supplied through a supply line 9 based on a specific mixing ratio thereat to improve. The other is such that excavated soil (b') which is improved and stored into a storage tank 10 in advance is sent to the inside of a hollow shaft 1a of the auger 1 through a transfer line 12 by operating a pressure pump 11, and that it is filled into an excavation section (c') underneath from the lower end of the shaft 1a.
