DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a destruction device for destroying an object to be destroyed by using the expansion force of a substance for destruction.

[0002]

2. Description of the Related Art Conventionally, there is a destruction device which breaks an object to be destroyed such as a concrete structure or a rock by using the expansion force of a substance for destruction.

[0003] This type of destruction device is used to immerse an electrode connected via a thin metal wire in a destruction substance such as water filled in a destruction container, and to supply the electrode with electric energy to the thin metal wire. Connected to an 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 so, the thin metal wire rapidly melts and evaporates, and at the same time, the destruction material rapidly evaporates and expands. The expansion force acts on the wall surface of the mounting hole, and the object to be destroyed can be destroyed.

[0005]

In the above destruction device, since a destruction substance to be filled in the destruction container is made of a stable substance such as water which does not easily maintain an expanding force, the destruction substance is not used. The expansion force acts only on the object to be destroyed instantaneously, and a sufficient destruction force may not be obtained.

Accordingly, an object of the present invention is to provide a destruction device that can solve the above-mentioned problems.

[0007]

Means for solving the problem in the present invention is to break down the electric energy supply circuit.
Supplying electrical energy to the metal wires in the container in a short time
While rapidly melting and evaporating thin metal wires,
Sudden vaporization of the destructive substance filled and immersed in fine metal wires
To destroy the object to be destroyed by the expansion force of this destructive substance.
A destruction device, wherein the substance for destruction is contained in a destruction container.
Flammable and stable substances are separated and filled
The fine metal wires are used as the flammable substance and the stable substance.
It was soaked across.

[0008]

[0009]

According to this configuration, the destruction container is filled with a flammable substance and a stable substance as a substance for destruction, and a thin metal wire is immersed in the flammable substance and the stable substance. When electric energy is supplied from the electric energy supply circuit to the thin metal wire in a short time, the thin metal wire rapidly melts and evaporates, and the combustible substance is vaporized and the stable substance is vaporized. As a result, a crack is generated in the object to be destroyed, and the destructive substance burned and vaporized pushes the crack over time.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a destruction device according to an embodiment of the present invention will be described with reference to the drawings. First, a destruction device 1 according to a first embodiment of the present invention will be described with reference to FIGS.

As shown in FIG. 1, a breaking device 1 according to a first embodiment of the present invention rapidly melts and evaporates a fine metal wire (for example, Cu is used) 2 of a discharge cable and immerses the fine metal wire 2. The destroying substance 3 is rapidly vaporized, and the object 4 is destroyed by the expansion force of the destroying substance 3 at that time.

The substance for destruction 3 is filled in a destruction container 6 mounted in a mounting hole 5 formed in the object 4 to be destroyed, and the destruction substance 3 is sealed by a plug member 7 attached to the destruction container 6. ing.

A discharge cable 12 is inserted into the plug member 7 as a pair, and the thin metal wire 2 is immersed in a destructive substance 3 by partially removing the covering member 13 of the discharge cable 12. As the destructive substance 3, a flammable (including explosive) liquid such as thinner or kerosene is used.

An electric energy supply circuit (not shown) is connected to the thin metal wire 2 so that electric energy is supplied to the thin metal wire 2 from the electric energy supply circuit.

Next, a destruction method using the destruction device 1 having the above configuration will be described. First, as shown in FIGS. 1 and 2,
The destruction container 6 is filled with the destruction substance 3, and the discharge cable 12
Is sealed with a plug member 7 through which the material has been inserted, and the destruction container 6 is mounted in the mounting hole 5 formed in the object 4 to be destroyed, and an object such as sand is filled in the mounting hole 5.

After this, electric energy is supplied from the electric energy supply circuit to the discharge cable 12 in a short time. Then, the thin metal wire 2 rapidly melts and evaporates, and the destructive substance 3 rapidly burns and evaporates (explodes).
Due to the expansion force (explosive force) of the destructive substance 3 at that time, as shown in FIG.

Then, as shown in FIG.
At the moment when the gas is burned and vaporized, a crack 8 is generated in the object to be destroyed 4 by the impact force, but after a short time t, the burned and destroyed substance 3 enters the crack 8 and the material 3 is expanded. The force acts on the crack 8 and pushes it apart.

In the graph of FIG. 5, the horizontal axis represents the elapsed time from the supply of electric energy, and the vertical axis represents the expansion force. In the figure, the solid line A indicates that the thin metal wire 2 rapidly melts and evaporates. The broken material 3 shows a state in which the substance 3 is rapidly burned and vaporized, and the broken line B shows a state in which the expansion force of the burned and destroyed substance 3 acts on the crack 8 generated in the object 4 to be broken. From this figure, it can be seen that the expansion force acts on the object 4 in a stepwise manner.

As described above, according to the first embodiment of the present invention, since the flammable liquid is used as the destructive substance 3 to be filled in the destruction container 6, the thin metal wire 2 is rapidly melted and evaporated. Cracks 8 generated when destructive substance 3 explodes rapidly
In addition, since the expansion force of the destruction substance 3 which has been vaporized acts in a stepwise manner, the crack 8 generated in the destruction object 4 is pushed and expanded, and the destruction object 4 can be reliably destroyed.

Next, a second embodiment of the present invention will be described with reference to FIG. In the destruction device 1 according to the second embodiment of the present invention, a jelly-like stable substance 15 and a liquid flammable substance 16 are separately filled in a destruction container 6 as the destruction substance 3, A thin metal wire 2 is immersed over a combustible substance 16 and a stable substance 15.

The other configuration is the same as that of the first embodiment, and the description is omitted. In the above configuration, when electric energy is supplied from the electric energy supply circuit to the discharge cable 12 in a short time, the thin metal wire 2 is rapidly melted and evaporated, and the jelly-like stable substance 15 is rapidly vaporized. The combustible substance 16 rapidly burns and evaporates.

At the moment when the stable substance 15 is rapidly vaporized and the combustible substance 16 is rapidly vaporized, the impact force generates a crack 8 in the object 4 to be destroyed. After that, the combustible substance 16 that has been burned and vaporized enters the crack 8, and the expansion force of the combustible substance 16 acts on the crack 8 generated in the destructible object 4, pushes and expands the crack 8, and causes the destructible object 4 to expand. Destruction surely.

As described above, according to the second embodiment of the present invention, the jelly-like stable substance 15
And the flammable substance 16 are filled separately,
Is immersed in the combustible substance 16 and the stable substance. Therefore, when electric energy is supplied from the electric energy supply circuit to the discharge cable 12 in a short time, the thin metal wire 2 rapidly melts and evaporates. The jelly-like stable substance 15 evaporates rapidly, and the combustible substance 16 evaporates rapidly.

At the moment when the stable substance 15 is rapidly vaporized and the flammable substance 16 is rapidly vaporized, the impact force causes a crack 8 to be generated in the object 4 to be destroyed, and a short time has elapsed. Later, the combustible substance 16 that has been burned and vaporized
The expansion force acts on the crack 8 generated in the object to be destroyed 4, pushes and expands the crack 8, and the object to be destroyed 4 can be reliably destroyed.
