METHOD OF CONSTRUCTING IMPROVED SLOPE GROUND IN EXECUTION OF SOIL IMPROVEMENT, AND MULTIPLE SOIL IMPROVING MACHINE

摘要

PROBLEM TO BE SOLVED: To save the usage of a soil improving agent for use in the improved slope ground developed in the ground, by forming steps at upper and lower edges of ground units protruding from a slope.;SOLUTION: The improved slope ground is developed by using a multiple soil improving machine which is set up by combining a plurality of soil improving machine units each having a rotation drive unit at an upper portion of an excavation rod having an excavation head at the tip of the same, so that the rotation drive units are fitted into a support frame, and arranging the pairing excavation rods side by side in a longitudinal direction. The improved slope ground is formed by successively arranging the improved ground units in the ground. Specifically tip of the respective excavation heads are located so as to be different in height based on an inclination angle of the improved slope ground. Then the steps which are unimproved areas are formed at the upper and lower edges of the ground units based on the difference in height. Thus by the formation of the unimproved areas of the ground units, the usage of the soil improving agent is saved.;COPYRIGHT: (C)2007,JPO&INPIT
