Abstract (en)
[origin: JP2018044429A] PROBLEM TO BE SOLVED: To enable a trench to be manufactured at a precise position in soil in an efficient mode.SOLUTION: A trench is manufactured by actuating at least a pair of cutting wheels mounted on a trench cutter lower end that faces soil and removing soil material. Fluid is introduced in the trench by at least one fluid nozzle on the trench cutter. The position of the trench cutter in the trench is controlled by multiple fluid nozzles through which fluid is supplied in a predetermined mode by a control means. The position of the trench cutter can be selectively changed by disposing multiple fluid nozzles through which fluid can be supplied in another mode by the control means.SELECTED DRAWING: Figure 1
