EXCAVATION METHOD THROUGH BIDIRECTIONAL COMMUNICATIONS AND FEEDBACKS FOR LONG DISTANCE PIPE LINE BURYING

摘要

The present invention provides an excavation method through bidirectional communications and feedbacks for long distance pipe line burying. The excavation method comprises: a shooting path setting step of setting a shooting path of a submarine pipe line between a start port and an arrival port; a bidirectional excavation step of forming a first excavation hole and a second excavation hole along the shooting path by using a road to which radio wave transmitters are attached by installing a press tool on each of the start port and the arrival port; and an excavation hole crossing step of receiving signals of the radio wave transmitters, calculating a separation distance between the radio wave transmitters, allowing one press tool to be connected to have a shooting path as much as the separation distance, and excavating a road, so that the first excavation hole and the second excavation hole are connected to each other.;COPYRIGHT KIPO 2018
