Abstract

PURPOSE:To enable reliable implanting of an improving agent into a given ground, by a method wherein, in a titled method for a soft ground, an improving agent implanting member, provided with an excavating cutter at the end, is inserted under an anhydrous state, and an improving agent is implanted in a given position from a non-return valve. CONSTITUTION:An implanting member A for ground improving agent is inserted into the ground to be improved under an hydrous state through the working of an excavating cutter 4. Then, a non-return valve 6 prevents the enterance of earth and sand in an outer peripheral ground into the implanting member A. After the implanting member A is inserted to a given depth, a ground improving agent is implanted into the outer peripheral ground through implanting ports 22. With the non-return valve 6 opened in a direction of a diameter, the ground improving agent is implanted into the outer peripheral ground through a gap between the non-return valve 6 and concavities 3 in a body 1 to prevent the occurrence of a return current by means of the nonreturn valve 6 and also the entrance of earth and sand into the implanting member A. When a given implanting is completed, the implanting member A is lifted by a full step, and an implanting work takes place again.
