<P>PROBLEM TO BE SOLVED: To recognize a water bottom ground shape in real time and to improve finish shape accuracy and work efficiency, regarding a drilling/leveling method by an underwater drilling/leveling work machine. <P>SOLUTION: A three-dimensional sonar 2 is provided in an underwater drilling/leveling work machine 7, a gyroscope or an inertial navigation device, a global positioning system device, a sound velocity meter device, and a personal computer for three-dimensional analysis, which is connected to the respective devices by cables or radio, inputs each data, makes a storage device record the data and makes a monitor three-dimensionally display it, are provided in a support barge provided with a remote controller for remotely controlling the work machine, and an SSBL positioning system 8 for measuring a position of the work machine is provided in the work machine and the support barge to configure a construction management device 1. The data of the three-dimensional sonar 2 is transmitted to the personal computer for three-dimensional analysis in the support barge 9, the work machine 7 is operated by the remote controller while confirming the finish shape of the ground of a work object in real time, and the underwater drilling/leveling work is performed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
