LAND MINE DISPOSING DEVICE

摘要

PROBLEM TO BE SOLVED: To stably perform a land mine disposal in a land mine disposing device. SOLUTION: This land mine disposing device for explosively disposing land mines in the ground by pressurizing the ground comprises a shaft 70 and a plurality of annular pressurizing rings 71A and 71B inserted into the shaft 70 and arranged parallel with each other along the shaft 70. The plurality of pressurizing rings 71A and 71B are arranged parallel with each other with their side faces brought into contact with each other. The inner diameter DRIof the plurality of pressurizing rings 71A and 71B is set larger by a specified dimension than the outer diameter DSof the shaft 70 so that the pressurizing rings can be vertically moved relative to the shaft 70 so that, even if a height different occurs between the adjacent pressurizing rings 71A and 71B, such a state that the side faces are brought into contact with each other in an annular area A surrounding the shaft 70 is maintained can be maintained in the adjacent pressurizing rings 71A and 71B.
