ECO-FRIENDLY SUBMARINE PIPELINE ESTABLISHING METHOD

摘要

PURPOSE: A laying device for an environmentally friendly submarine pipe conduit is provided to minimize the generation of construction wastes and environmental contamination caused by bentonite sludge. CONSTITUTION: A laying device for an environmentally friendly submarine pipe conduit comprises as follows. A drill head excavated hole (110) is excavated with an existing method from a start unit (1) to a final unit (2). Stone powder and bentonite are discharged by being blown in the direction of the start unit by connecting a reverse blow-out device and blowing cleaning water and air. A cleaning water excavated hole (210) is excavated by the pressure of the cleaning water through a cleaning water blow-out device (200) to the final unit.
