Abstract
PURPOSE: To dig an arbitrary crosssection without generating remaining parts after digging by arranging a number of sub-digging machines on the outer peripheries of main digging machines and arranging a number of jet water jetting nozzles among these sub-digging machines. CONSTITUTION: Main digging machines 14 dig circular crosssections respectively with a large crosssection and have radially extending slit-like openings 20 for taking in earth and sand. Sub-digging machines 16 and 18 for digging small circular crosssections along a crosssectional shape to be digged are arranged on the outer peripheries of these main digging machines 14. Jet water jetting nozzles 26 are arranged among these sub-digging machines 16 and 18.
