APPARATUS FOR EXCAVATION WORK AND METHOD FOR EXCAVATION THEREOF

摘要

The present invention relates to a ground excavating apparatus, and a ground excavating method using the same. The ground excavating apparatus comprises: an excavating part; a circulating liquid supply part; a mixing part; a filling member supply part; and a blocking part. The excavating part excavates the ground; the circulating liquid supply part supplies a circulating liquid to discharge excavated soil generated as the excavating part excavates the ground; the mixing part forms a filling liquid to be supplied to the soft ground; the filling member supply part supplies a filling member to the mixing part, where the filling member mixed with the circulating liquid forms the filling liquid; and the blocking part blocks the circulating liquid from moving to the soft ground in such a manner that the filling liquid fills in air holes formed on the soft ground when the excavating part reaches the soft ground. According to the present invention, the filling liquid fills in the air holes to prevent the circulating liquid from leaking to the soft ground; thus preventing the ground from collapsing during excavation.
