<p><P>PROBLEM TO BE SOLVED: To provide a method of pulling out and removing embedded cables which can avoid traffic hindrance and damage of buried objects such as power transmission lines, reduce a construction period and a construction cost, has excellent working environment because fixing sand is fluidized and sucked with less used water quantity, causes no influence on the ground or other buried objects, and has excellent workability in openings. <P>SOLUTION: Two or more openings from the surface of ground to a trough are formed with a predetermined distance, and both ends of the power cable are cut while exposing an end surface in the longitudinal direction of the trough. In the trough, the following are used, i.e. a jetting nozzle 11 for jetting water to be used for softening the cable fixing sand along the power cable and fluidizing it, and a suction nozzle 14 arranged on the side of the jetting nozzle 11 and used for immediately continuously sucking the fluidized sand to expose the power cable. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
