Abstract

PROBLEM TO BE SOLVED: To bore an insertion hole of a bomb searcher in safety by disposing a high pressure water jet nozzle at the lower end in a nozzle insertion hole forming pipe extending vertically, suspending the insertion hole forming pipe above a bomb searching point and jetting high pressure water from the high pressure water jet nozzle. SOLUTION: When an insertion hole H is formed in the ground G, a high pressure water jet nozzle 3 is disposed at the lower end in a nozzle insertion hole forming pipe 1, which is then suspended above a bomb searching point P by means of a suspension working machine 10. Subsequently, a clamper 12 is lowered while jetting high pressure water W from the high pressure water jet nozzle 3 and the nozzle insertion hole forming pipe 1 is pushed into the ground G up to a specified depth while digging the ground. Thereafter, a coupling body 13 is uncoupled from the upper end of the pipe 1, the clamper 12 is lifted by means of the working machine 10 and a water guide pipe 14 is drawn out before the high pressure water jet nozzle 3 is collected. Finally, a bomb searcher is inserted into an insertion hole made in the nozzle insertion hole forming pipe 1 pushed into the ground G.
