PROBLEM TO BE SOLVED: To treat a buried article surely by installing a buried-article detecting means at the working-machine front end of an arm type working machine and mounting a paint discharge means near the buried-article detecting means. SOLUTION: A buried-article detector 12 as a buried-article detecting means is set up at the front end of a working arm 9 for an arm type working machine, and a paint ejector 14 as a paint discharge means is fitted near the detector 12. The buried article such as an explosive substance buried into a ground can be detected surely by horizontally moving the detector 12, and the buried articles can be detected certainly within a wide range when operation, in which the arm type working machine is stationed beforehand and the buried articles are detected while slewing a revolving super structure, the arm type working machine is shifted after the buried articles are detected at regular interval and the buried articles are detected while swivelling the revolving super structure 8, is repeated. Paints such as powder, a liquid, etc., are injected from an injection nozzle 15 for the paint ejector 14, and marks can be put surely at buried places, where the buried articles such as the explosive substance are detected. |
