DREDGING SUCTION AND SAND DISCHARGE UNIFICATION DREDGING APPARATUS AND DREDGING METHOD USING APPARATUS

摘要

The present invention relates to a sand discharge unification dredging apparatus and a dredging method using the same and is to suck dredged soil in water and then discharge the dredged soil onto the land by using an excavator arm and a boom as configurations for dredging without using a separate pipe. The dredging suction and sand discharge unification dredging apparatus according to the present invention comprises: a buoyant hull (10); an excavator (20) which is mounted on a deck of the buoyant hull, and includes a cutter (26) crushing underwater ground, an arm connected to the cutter, and a boom (22) connected to the arm; a dredged soil inflow pipe (30) which has a pipe shape, and one side of which is connected to the front end of the arm of the excavator and an inflow end of the other side of which corresponds to the periphery of the cutter; a dredged soil discharge pipe, one side of which is connected to the boom of the excavator and the other side is connected to the land; and a pump (50) which sucks and discharges the dredged soil through the inside of the discharge pipe. The arm and boom of the excavator are configured in a pipe shape having hollow dredging discharge paths (22a, 24a) therein, and the dredged soil crushed by the cutter is discharged through the dredged soil inflow pipe and the dredging discharge paths of the arm and boom by pumping force of the pump.;COPYRIGHT KIPO 2017
