<p>The present invention relates to a ground excavator and an underground polygonal shoring method to form underground walls by excavating the ground, wherein a vibro-device and an auger device for excavating the ground are formed, and a polygonal plate, a taper portion, and an auxiliary excavating portion are formed to be coupled with the vibro-device and excavate the ground in a polygonal shape using the vibro-device. The objective of the present invention is: to increase effectiveness by doubly excavating poor ground composed of sand etc, using the auger device and the vibro-device; to prevent the inflow of underground water and also improve straightness during excavation by forming an excavated surface in a polygonal shape, inserting polygonal piles into the excavated surface, and reducing the interval between the piles, for use as a slurry wall construction method; and especially to enable excavation in a model which has regular shapes such as a ?-shape or a ?-shape by excavating the ground in a polygonal shape.</p> |
