[0002]

2. Description of the Related Art Conventionally, there is a destruction method in which an object to be destroyed such as a concrete structure or rock is destroyed using a destruction device.

[0003] In the destruction apparatus used in this destruction method, an electrode connected via a thin metal wire is immersed in a destruction substance (water or oil or the like is used) filled in a destruction container, and the electrode is connected to the thin metal wire. And an energy supply circuit for supplying electric energy to the energy supply circuit.

[0004] In order to destroy an object to be destroyed such as a bedrock using such a destruction device, a mounting hole is formed in the object to be destroyed, a destruction container is mounted in the mounting hole, and a capacitor provided in an energy supply circuit is provided. The electric energy charged and stored in the battery is discharged and supplied to the thin metal wire in a short time. By doing this,
The metal wire rapidly melts and evaporates, and the substance for destruction rapidly evaporates and expands. The expansion force acts on, for example, the wall surface of the mounting hole to destroy the object to be destroyed.

[0005]

In the above destruction method, when a mounting hole is formed in an object to be destroyed such as rock and a destruction container is mounted in the mounting hole for use, the substance for destruction is vaporized. Since the expansion force at that time acts on the wall surface of the mounting hole, the object to be destroyed can be broken by applying a sufficient impact.

However, when the object to be destroyed is a plate-shaped object, the mounting hole may not be formed in some cases. In such a case, the destruction container is simply used by contacting the object to be destroyed. The expansion force when the substance was vaporized almost escaped into the air, and it was not possible to give sufficient destructive power.

Therefore, an object of the present invention is to provide a destruction method capable of solving the above-mentioned problems.
