BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is to melt and vaporize an electric energy to a molten vaporized substance (for example, a thin metal wire) in a short time, and to prevent a phenomenon (for example, impact force) of a process accompanying the molten vaporization. The present invention relates to a destruction apparatus and a destruction method for destroying an object to be destroyed such as a concrete structure or rock.

The expansion force associated with the melting and vaporization of is transmitted to the peripheral surface of the mounting hole of the object to be destroyed,
Objects to be destroyed are destroyed and weakened.

[0004]

In the conventional destruction apparatus described above, in order to sufficiently transmit the expansive force associated with the melting and vaporization of the thin metal wire 30 to the object to be destroyed, the space between the destruction container 26 and the mounting hole is eliminated. It is necessary to. However, as for the diameter of the mounting hole, the diameter in the depth direction of the mounting hole is not constant depending on the situation at the site and the opening means of the mounting hole, and the diameter of the destruction container 26 and the mounting hole is fixed. It is not always possible to ensure that there are no gaps between them. Therefore, the diameter of the mounting hole is formed in advance to be larger than that of the destruction container 26 so that the destruction container 26 can be easily inserted into the mounting hole. However, forming the mounting hole with a diameter larger than necessary increases the working time.

Further, if there is a gap between the destruction container 26 and the mounting hole, the expansive force when the thin metal wire 30 is melted and vaporized is not sufficiently transmitted to the object to be destroyed as described above. Therefore, it is necessary to fill the gap between the destruction container 26 and the mounting hole with a filler that fills the gap. Therefore, an object of the present invention is to provide a destruction device and a destruction method capable of solving the above problems.
