This will be described with reference to a graph showing the relationship between P and its occurrence time t, and a cross-sectional view of FIG. 4 in which another object is destroyed.

As shown in FIG. 1, a destruction device 1 according to a first embodiment of the present invention comprises a destruction container 2 made of plastic rubber (synthetic rubber) or waterproof paper and a destructive fluid substance 3 (eg, water). A pair of electrode rods 4, 4 (for example, made of Cu) are inserted into the top plate 2a of the destruction container 2 through the through hole 2b, and the two electrode rods 4, 4 are connected to the top plate 2a with nuts B1 ( Or caulking), which is fixed by the flowable substance for destruction 3
And is sealed in the destruction container 2.

When the object to be destroyed such as a bedrock is destroyed, the destroying container 2 is mounted in a mounting hole 20a formed in the object to be destroyed. The two electrode rods 4, 4 have holding members 7 for holding the electrode rods 4, 4 in parallel in the middle thereof.
7, a pair of fine metal wires 8 a and 8 b (for example, made of Cu and Al) are provided at the tips of the electrode rods 4 and 4 in the depth direction of the destruction container 2 (the depth direction of the mounting hole 20 a). ), And are mounted by welding or caulking in parallel with a direction perpendicular to the depth direction of the destruction container 2.

The portions where the two electrode rods 4, 4 protrude from the top plate 2a are used as terminals 5, 5, and a terminal cover 6 for preventing the terminals 5, 5 from forming an insulating film on the top plate 2a. Is attached.

An energy supply circuit 9 for supplying electric energy to the two metal wires 8a and 8b is provided.
The energy supply circuit 9 includes a power supply 10 connected to the terminals 5, 5, and a power supply 10 connected to the terminals 5, 5.
A capacitor connected in parallel between the
Path) 13 and series between power supply device 10 and one terminal 5
The electric energy stored in the capacitor 13
A control circuit 11 for controlling the amount of energy;
Discharge switch connected between path 11 and one terminal 5
12 .

Next, a breaking device 1 according to a first embodiment of the present invention.
A destruction method for destroying the bedrock H1 (destroyed object) using will be described. As shown in FIG. 2, a mounting hole 20a for mounting the destruction container 2 of the present invention is drilled in the rock H1, for example, in a vertical direction, and the destruction container 2 is mounted in the mounting hole 20a.

The energy supply circuit 9 is connected to the terminals 5 and 5, electric energy of a predetermined capacity is stored in the energy storage circuit 13, and the discharge switch 12 is turned on. By doing so, both metal thin wires 8 can be formed in a short time.
Electric energy is divided and supplied to a and 8b.

Since the thin metal wires 8a and 8b are arranged apart from each other in the depth direction of the destruction container 2, first, electric energy is supplied to one of the thin metal wires 8a on the side closer to the energy supply circuit 9; The electric energy is supplied to the other thin metal wire 8b with a very short time. In this way, both the thin metal wires 8a and 8b are melted and evaporated, and the fluid material for breaking 3 is vaporized, whereby the rock H1 can be broken or weakened by its impact force.

When electric energy is supplied to the other thin metal wire 8b, since the electric energy has already been consumed by one thin metal wire 8a, the electric energy supplied to the other thin metal wire 8b is reduced by that much. Although reduced, the impact due to the melting and evaporation of one of the thin metal wires 8a is transmitted to the object to be destroyed, so that the impact can be sufficiently applied to the object to be destroyed.

In order to obtain a large impact force, the voltage value of the power supply device 10 may be increased. However, in consideration of technical restrictions, energy efficiency, and destruction efficiency, a single point discharge using a single metal wire is considered. Also, since the multi-point discharge using the electric energy stored in the energy storage circuit in a divided manner is better, the two thin metal wires 8a and 8b are used as described above.
Are connected to the electrode rods 4 and 4 to destroy the object to be destroyed. (For example, a two-point discharge of 1000 V to 50 μF can improve the impact force against the object to be destroyed rather than a one-point discharge of 1000 V to 100 μF.) Although not shown, the middle part (side part) of the rock is broken. In this case, a mounting hole is drilled in the horizontal direction, a breaking device is mounted in the mounting hole from the side, and electric energy is supplied to the thin metal wire to break it in the same manner as described above.

[0026] Even if a mounting hole is formed in the middle part of the bedrock in the horizontal direction, the destruction vessel of the destruction device is already filled with the destructive fluid material, so that the destructive fluid material spills out of the mounting hole. Therefore, according to the first embodiment of the present invention, it is possible to cope with any direction of the mounting hole drilled in the rock.

Next, a destruction method for destroying a structure H2 (destructible object) such as a building will be described with reference to FIG. This is when constructing the pillars of the structure H2, etc.
The breaking device 1 configured as above in concrete is
It is buried in a predetermined location in advance.

2, the terminal block 15 is covered with a terminal cover 16.

When the structure H2 is destroyed, the energy supply circuit 9 is connected to the terminals 5 and 5 in the same manner as in the above embodiment.
A predetermined amount of electric energy is stored in the energy storage circuit 13.
And the discharge switch 12 is turned on.

In this manner, electric energy is divided and supplied to each of the thin metal wires 8a and 8b in a short time, and the thin metal wires 8a and 8b are melted and evaporated, so that the breaking fluid 3 is vaporized. The structure H2 can be broken or weakened by the impact force.

According to the first embodiment of the present invention, the destruction device 1 does not explode unless electric energy is supplied. Therefore, even if the destruction device 1 is buried in the structure H2 in advance, the destruction device 1 is not blasted. It is safe because there is no fear of explosion due to vibration of the structure H2. In addition, by embedding the destruction device 1 in the structure H2 in advance, it is possible to omit a process for installing a device such as drilling a mounting hole in the structure H2. it can.

As described above, according to the first embodiment of the present invention,
Even if it is necessary to drill mounting holes in the object to be destroyed, such as rock, in the horizontal or elevation direction, the destruction vessel is filled with the fluid for destruction, and the fluid for destruction will pass through the mounting holes. It does not spill out and can be mounted in mounting holes in all directions, and the destruction device in this embodiment does not explode unless electric energy is supplied, so it can be used like a building or a pavilion. In the case of an object to be destroyed whose time for destruction is set in advance, even if the destruction device is embedded in the object to be destroyed, there is no fear of explosion due to vibration of the object to be destroyed like dynamite, and furthermore, A step for installation, such as drilling a mounting hole in the object to be destroyed, can be omitted.

A predetermined amount of electric energy is divided and supplied to each of the thin metal wires 8a and 8b, and a two-point discharge is performed, so that the amount of electric energy necessary to obtain the same impact force as in the case of one-point discharge is reduced. I need less.
