Description

  The present invention relates to a discharge impact destruction apparatus that can explode an explosive substance with an impact force generated by electric discharge to destroy a structure such as concrete.

Recently, as a device for safely destroying a structure such as concrete, a device using a discharge cartridge that is safe to handle instead of dynamite has been proposed.
In this discharge cartridge, for example, a thin metal wire connected between a pair of electrodes is disposed in a cylindrical container, and a force transmission substance such as water and oil is filled, and a predetermined amount is supplied from the power supply device to the thin metal wire. The electric energy is supplied at a stretch to melt and vaporize the fine metal wire, and the impact force (hereinafter also referred to as discharge impact force) generated due to the volume expansion at the time of the melt and vaporization is transmitted to the surroundings through the force transmitting substance. This destroys the structure.

  When the structure is partially destroyed, a hole is formed in the destroyed portion, and a discharge cartridge is inserted into the hole, and electric energy is supplied to the fine metal wire to cause destruction (Patent Document) 1).

By the way, when a hole for inserting the discharge cartridge cannot be formed, a destructive member such as a shell (for example, a wedge) is formed at the end portion of the cylindrical container to directly collide with the structure and destroy it. ) Is inserted, and electric energy is supplied to the portion where the discharge impact force is arranged adjacent to the end portion, that is, the metal thin wire, and the member for destruction is tubed by the discharge impact force generated by the melt vaporization. It was fired from a cylindrical container and partially destroyed (see Patent Document 2).
See JP-A-10-331447 See JP-A-11-76854

  According to the configuration of the above conventional discharge cartridge, the cylindrical container is inevitably long due to the firing of the bullet-shaped destruction member. For example, when the destruction portion is located in a narrow place, the discharge cartridge itself In addition, it is necessary to perform a work of loading the member for destruction into the cylindrical body on the site, which requires troublesome preparation work.

  Therefore, the present invention provides a discharge impact destruction apparatus that does not require troublesome preparation work when destroying a structure using a discharge impact force and can easily perform the destruction work even in a narrow place. The purpose is to provide.

In order to solve the above-mentioned problems, a discharge shock destruction apparatus according to claim 1 of the present invention is a box-shaped body having a bottom wall portion and having a space chamber formed therein, and the box-shaped body is engaged by a locking member. A lid that can be closed to close the upper opening of the box-shaped body, a metal thin wire that is disposed in the space chamber of the box-shaped body and connected to a pair of electrical wires connected to a power supply device, and It consists of explosive substances filled in the space room,
On the inner surface of the lid body, a plate-like protrusion having an outer peripheral surface along the inner peripheral surface of the space chamber and entering the space chamber is formed.
The locking member is broken by the explosive force of the explosive substance filled in the space chamber, and the box-shaped body and the lid body are not damaged by the explosive force of the explosive substance filled in the space chamber. It is designed to give strength.

  According to a second aspect of the present invention, there is provided a discharge shock destruction apparatus including the box-like body and the lid body of the destruction apparatus according to the first aspect made of a conductive material, and the plate-like protruding portion surface of the lid body and the box. An insulating material for preventing contact with a fine metal wire is disposed on the bottom surface of the space body side.

Moreover, the discharge impact destruction apparatus according to claim 3 of the present invention is capable of closing the opening on both sides by being locked to the frame-shaped side wall body with a predetermined height and the frame-shaped side wall body via a locking member. A pair of lids, a metal wire arranged in a space chamber formed inside the frame-shaped side wall body and connected to a pair of electric wires connected to a power supply device, and an explosion filled in the space chamber It is composed of sex substances,
On the inner surface of the lid body, a plate-like protrusion having an outer peripheral surface along the inner peripheral surface of the space chamber and entering the space chamber is formed.
In addition, the locking member breaks due to the explosive force of the explosive material filled in the space chamber, and the box-like body and each lid body are damaged by the explosive force of the explosive material filled in the space chamber. It is designed to give strength that does not.

  According to a fourth aspect of the present invention, there is provided a discharge impact breaking device in which each lid in the breaking device according to the third aspect is made of a conductive material, and a thin metal wire is formed on the surface of the plate-like protruding portion of each lid. Insulating material that prevents contact with is arranged.

According to a fifth aspect of the present invention, there is provided a discharge impact destruction apparatus according to any one of the first to fourth aspects, wherein nitromethane is used as an explosive substance.
Moreover, the discharge impact destruction apparatus which concerns on Claim 6 makes the latching member in the destruction apparatus in any one of Claims 1 thru | or 4 be a volt | bolt or a welding part.

  According to the structure of the said Claim 1 or Claim 3, a metal thin wire is arrange | positioned in the space room of the box-shaped body or frame-shaped side wall body to which the cover body was attached via the latching member, and explosion, such as nitromethane In addition to filling with explosive substances, the explosive substance is exploded by the discharge impact force generated by the melt vaporization of fine metal wires, and the lid is blown (released). Unlike the one loaded with the destructive member, the apparatus itself can be shortened, that is, thinned, so that it is not necessary to form a hole for inserting the discharge cartridge, and it is not possible to form a hole. Even in such a place, the destruction can be performed partially and easily by simply inserting the gap into the gap and supplying electric energy.

  In addition, since a plate-like protrusion that enters the space chamber is formed on the inner surface of the lid, the locking member extends a little due to the explosive force of the explosive substance, and the lid protrudes slightly. In addition, at least the front end surface side of the plate-like protruding portion is still in the space chamber, and the gap between the outer peripheral surface of the plate-like protruding portion and the side wall portion of the box-like body is slight, The explosive reaction is carried out continuously with almost no explosive substance jetting out (leaking), thus increasing the explosive power. That is, the power of explosive power increases and a larger explosive power acts on the lid. In other words, the kinetic energy of the lid increases and the destructive force increases. Naturally, since the reaction efficiency of explosive substances is improved, it becomes economical.

  In addition, since it has an insulating material that prevents the fine metal wires from coming into contact with the box-shaped body or lid, the metal fine wires contact the box-shaped body or the lid at the time of detonation, causing an electrical short circuit. It is possible to prevent the power supply device from being damaged due to the short circuit.

  Furthermore, by using a bolt as a locking member for locking the lid to the box-shaped body or the frame-shaped side wall body and adjusting its cross-sectional area, the explosion reaction time can be adjusted to control the explosive force, In addition, by appropriately changing the cross-sectional area for each bolt, the direction in which the lid protrudes can also be controlled.

[Embodiment]
Hereinafter, a discharge shock destruction apparatus according to an embodiment of the present invention will be described with reference to the drawings.
First, the discharge shock destruction apparatus will be described with reference to FIGS.

  As shown in FIG. 1 and FIG. 2, the electric discharge impact destruction apparatus 1 includes a bottom wall portion 11a having a rectangular shape in plan view, for example, a square wall portion 11a and a side wall portion 11b erected around the bottom wall portion 11a. A box-like body 11 made of metal (an example of a conductive material) having a shape like a thin lunch box in which a space chamber 11c having a circular shape (for example, a square shape such as a square) is formed; A lid 12 made of metal (an example of a conductive material) capable of closing a circular opening (upper opening) 11d above the box-shaped body 11 and a space chamber 11c of the box-shaped body 11 are arranged. In addition, a fine metal wire 14 having both ends connected to one end side of the pair of device-side electric wires 13 and an inner surface of the lid body 12 (a space chamber side surface when the lid body is attached, and a circular shape to be described later) And the bottom wall of the box-shaped body 11 A sheet-like insulating material (for example, a plastic sheet, a plastic plate, etc.) is used to prevent contact (electrical short circuit) with the fine metal wires 14 disposed on the inner surface (the space chamber side surface) of 11a. , Which is unnecessary when the lid and the box are made of a non-conductive material) 15 and liquid nitromethane (an example of an explosive substance) filled in the space chamber 11c. 16) and a power source device 17 (shown in FIG. 3) connected to each other end side of the device-side electrical wiring 13 drawn from the box-shaped body 11, and the box-shaped A rod-shaped locking member for locking the lid 12 to the body 11 is provided with a predetermined number of bolts 18 and nuts 19, for example.

  In addition, for the metal thin wire 14, the device-side electric wiring (covered wire is used) 13 connected to both ends thereof is used as a fixing material (for example, a metal or synthetic resin band). Naturally, a synthetic resin material is used, and insulation is performed between the device-side electrical wiring and the box-like body). It is fixed to the wall 11a. The device-side electrical wiring 13 is provided through the through-hole 11e formed in the side wall 11b of the box-shaped body 11, and the through-hole 11e after the device-side electrical wiring 13 is inserted is provided in the through-hole 11e. A padding (for example, putty material) is applied to keep the sealed state. In addition, a filling port 11f for filling the nitromethane 16 into the space chamber 11c is formed at an appropriate place on the side wall portion 11b, and a plug 21 is applied (for example, screwed) after filling to close the plug. It is.

  The box-like body 11 has been described as being thin like a lunch box. Specifically, the height (H) of the box-like body 11 and the length (L) of one side thereof are described. The ratio is preferably 1 to 2 or less. In addition, the ratio of the height (H ′) and the length (L) of one side of the box-like body 11 with the lid 12 attached is 1: 1 at most.

  In addition, a circular plate-like projecting portion 12a having a predetermined depth (also thickness) (h) and having the same shape as the space chamber 11c is formed on the inner surface of the lid body 12 in the space chamber 11c. ing. And the outer peripheral surface of this plate-shaped protrusion part 12a is along the inner peripheral surface of the space chamber 11c, that is, the outer peripheral surface and the inner peripheral surface of the space chamber 11c (the inner peripheral surface of the side wall portion 11b). In the meantime, when the lid 12 itself is deformed with a predetermined explosive force (described later), a slight gap that can insert the plate-like protruding portion 12a into the space chamber 11c without hindrance is obtained. Is dimensioned to be closed. Of course, when the planar view shape of the space chamber 11c is a rectangular shape, for example, a square shape, the planar view shape of the plate-like protruding portion 12a is also a rectangular shape, for example, a square shape.

  Further, regarding the material [for example, steel (particularly cast steel), stainless steel, aluminum or the like is used] and the thickness of the box-like body 11 and the lid body 12, the explosive force of the nitromethane 16 filled in the space chamber 11c. Is selected to have strength that will not break. The outer shape of the lid 12 is a shape that matches the outer shape of the box-shaped body 11, that is, a square.

  About the bolts 18 for attaching the lid 12, as shown in FIG. 1, a plurality of, for example, eight are equally arranged around the space chamber 11 c, and according to the amount of nitromethane 16 filled, That is, a material having such a strength as to produce a desired explosive force is selected so that a predetermined explosive reaction rate can be obtained. This explosion reaction rate indicates how much of the explosive substance explodes. If this reaction rate is high, it indicates that the power of the explosion is large.

  Further, regarding the strength of the bolt 18, for example, the nitromethane 16 at a position far away from the thin metal wire 14 that cannot be detonated only by the discharge impact force is explode by the explosive force of the nitromethane 16 initiated near the thin metal wire 14 Even if the bolt 18 extends and the cover 12 jumps out a little while the space for accommodating the nitromethane 16 (the space chamber 11c portion) increases until the explosion reaction rate is sufficiently increased. The protrusion 12a has a predetermined strength (locking ability) to such an extent that the protruding portion 12a does not escape from the space chamber 11c, that is, the nitromethane 16 hardly leaks to the outside. Specifically, the predetermined explosive force corresponding to the predetermined intensity is an explosive force of a semi-complete explosion level in which the explosion reaction rate is sufficiently increased (for example, about 80 to 90%).

  In this way, there is a time difference from the initial explosion to the pop-up of the lid body 12, but there is a time difference, and the transmission itself occurs in a short time. Therefore, an explosion of about 80 to 90% is required until the bolt 18 is broken. If the reaction rate is obtained, it is estimated that the explosion reaction rate approaches 100% as a whole. Therefore, the bolt 18 may be deformed such as elongation, but the locked state can be maintained until the target explosion reaction rate. It is made to have such intensity | strength.

  In addition, if the intensity | strength of the volt | bolt 18 is small, the cover body 12 will jump out early, the explosion reaction amount of the nitromethane 16 will decrease (use efficiency will fall), and it will become uneconomical and naturally, as a whole The explosive power of becomes small.

  Further, as shown in FIG. 3, the power supply device 17 includes a high-voltage DC power supply 31, a capacitor 33 connected in parallel to the DC power supply 31 via a charging electrical wiring 32, and the charging electrical wiring. 32, a charge control circuit 34 for controlling the amount of electricity charged in the capacitor 33, a connection electric wiring 35 for connecting the metal thin wire 14 to the capacitor 33 in parallel, and the connection It comprises a discharge switch 36 provided in the middle of the electrical wiring 35.

  In the power supply device 17, a predetermined amount of electricity is stored in the capacitor 33 by the charge control circuit 34 and the discharge switch 36 is turned on to supply a predetermined amount of electric energy (electric amount) to the metal wire 14 at once. Then, the metal thin wire 14 is instantly melted and vaporized, and a discharge impact force due to the instant melt vaporization is generated and transmitted instantaneously, and a predetermined range (a range satisfying the initiation condition) of the nitromethane 16 is initiated by the discharge impact force. However, in a very short time, the explosion reaction (transfer) of the remaining nitromethane 16 proceeds from the fine metal wire 14 to the outside, and finally, all the nitromethane 16 explodes (complete explosion) and is desired. The explosive power of can be obtained.

Next, a method for partially destroying a concrete structure, for example, using the above discharge impact destruction apparatus will be described.
First, the mechanism for generating the discharge impact force will be described by focusing on the discharge impact destruction apparatus 1 itself.

  Before the discharge, as shown in FIG. 4A, the metal thin wire 14 connected to the device-side electric wiring 13 is fixed to the bottom wall portion 11a of the box-shaped body 11 via the fixing member 20, Then, after the lid body 12 is locked to the box-shaped body 11 via the bolt 18 and the nut 19, the nitromethane 16 is filled into the space chamber 11 c from the filling port 11 f formed at an appropriate position of the box-shaped body 11. Of course, at this time, the sheet-like insulating material 15 is disposed on the inner surface of the lid 12 and the inner surface of the bottom wall portion 11a.

  After filling, the filling port 11f is closed by the stopper 21, and a sealing agent (for example, silicon grease or the like) 22 is arranged at the contact portion between the lid 12 and the box-like body 11 so as to be sealed. Is done. The mounting hole of the bolt 18 and the threaded portion of the plug 21 are filled with the same sealing agent as described above.

  In this state, when a predetermined electric energy is supplied to the fine metal wires 14 at once by the power supply device 17, the fine metal wires 14 are melted and vaporized as shown in FIG. Detonate. When the nitromethane 16 is detonated, the portion in the vicinity of the fine metal wire 14 explodes. Subsequently, the remaining portion around the debris is chained to the lid 12 side and to the outer peripheral direction due to the already detonated impact force. As a result, the explosive power increases. Due to this explosive force, the bolt 18 extends a little and the cover 12 slightly protrudes, but at this time, at least the front end surface side of the plate-like protruding portion 12a is still in the space chamber 11c, and the explosion has occurred. Due to the slight deformation of the lid body 12 at the time, the gap between the outer peripheral surface of the plate-like protruding portion 12a and the side wall portion 11b of the box-like body 11 is almost closed, so that the nitromethane 16 in the space chamber 11c almost jets outward. If it is not (even if it leaks, it is a small amount), the explosion reaction will be continued and the explosive power will increase. That is, the power of the explosive force increases and a larger explosive force acts on the lid body 12. In other words, the kinetic energy of the lid 12 increases and the destructive force increases. Naturally, since the reaction efficiency of nitromethane 16 is improved, it is economical. Of course, since the mass of the lid 12 is increased by the amount of the plate-like protrusion 12a, the breaking force is increased.

  Then, as shown in FIGS. 4C to 4D, when the explosion reaction of the nitromethane 16 proceeds and the explosive force exceeds the total breaking force of the bolt 18, that is, the explosive force of the quasi-complete explosion level is exceeded. In this case, the lid 12 jumps out.

  Here, the effect when the plate-like protrusion 12a is provided on the lid 12, that is, the explosion reaction rate, is shown in the graph of FIG. FIG. 5 is a graph showing the relationship between the insertion depth (h) of the plate-like projecting portion 12a into the space chamber 11c, the reaction rate of nitromethane (explosion reaction rate), and the generated energy. The explosion reaction rate and generated energy increase in proportion to the depth.

Next, a specific example of the destruction work will be briefly described.
FIG. 6 shows a case where the rock G is destroyed.
As shown in FIG. 6 (a), the above-mentioned discharge impact destruction apparatus 1, that is, the metal thin wire 14 is arranged in the rift Gs that has been formed in the rock mass in advance or has been naturally formed, and the nitromethane 16 is provided. If the box-shaped body 11 filled with the lid body 12 is arranged and then the electric energy is supplied to the metal thin wire 14 from the power supply device 17 connected through the electric wiring 13 at once, FIG. As shown in FIG. 5, the split Gs can be destroyed and the rock part Gp to be destroyed can be dropped and destroyed.

FIG. 7 shows a case where a surface portion of a reinforced concrete structure is destroyed.
As shown in FIG. 7A, the discharge shock destruction apparatus 1 is held at the tip of the arm portion Ra of the heavy equipment for work, and the lid body 12 is moved so as to face the destruction surface K. If the electric energy is supplied at a stroke, the lid body 12 is ejected (released) toward the fracture surface K, and the collision force causes the fracture surface K to move as shown in FIGS. 7 (a) and (b). Can be partially destroyed.

FIG. 8 shows a case where a part of a reinforced concrete floor, wall or the like is limitedly broken.
As shown in FIG. 8, when the wall part P such as a reinforced concrete floor or wall is destroyed in a limited manner, a discharge is caused on the inner bottom surface of the bottomed cylindrical mounting body 41 that can cover the wall part P. If the impact destruction apparatus 1 is attached, and the opening of the cylindrical attachment body 41 is pressed so as to cover the destruction portion and electric energy is supplied to the metal thin wire 14 at once, only that portion can be safely destroyed. can do. The cylindrical attachment body 41 also has a function as a debris scattering prevention member (safety member). 6 to 8, the illustration of the sheet-like insulating material 15 is omitted.

  In this way, the fine metal wires 14 are arranged and filled with the nitromethane 16 in the space chamber 11c of the box-like body 11 to which the lid 12 is attached via the bolts 18, and the fine metal wires 14 are melted and vaporized. Since the nitromethane 16 is exploded by the discharge impact force, the device itself can be shortened, that is, made thinner, unlike the conventional case where the shell-shaped destruction member is loaded in the cylindrical container. Even in a narrow place where a hole for inserting a cartridge cannot be formed or a hole cannot be formed, it is partially and easily destroyed by simply inserting it into the gap and supplying electric energy. be able to.

  In addition, since the sheet-like insulating material 15 that prevents the fine metal wires 14 from contacting the box-like body 11 and the lid body 12 is provided, the fine metal wires 14 come into contact with the box-like body 11 or the lid body 12 at the time of detonation. Thus, it is possible to prevent damage on the power supply device 17 side due to the occurrence of an electrical short circuit.

  Furthermore, since the bolt 18 which is a rod-shaped locking member is used to lock the lid 12 to the box-shaped body 11, the initiation force, that is, the explosion reaction time can be reduced by adjusting the cross-sectional area of the bolt 18. The explosive force can be controlled by adjusting, and the direction in which the lid 12 protrudes can also be controlled by appropriately changing the cross-sectional area of each bolt 18.

  In the above-described embodiment, the sealing agent 22 is disposed between the lid 12 and the box-like body 11, but a more reliable sealing is achieved by interposing a packing in addition to this sealing agent. be able to.

  Moreover, in the said embodiment, although the volt | bolt and the nut were used for attaching a cover body to a box-shaped body, as shown in FIG. 9, you may make it use only the volt | bolt 18, for example. In this case, the screw portion of the bolt 18 is inserted through the lid body 12 and screwed into the side wall portion 11 b of the box-like body 11.

  By the way, in the said embodiment, although the rod-shaped thing, ie, the volt | bolt, was used as a locking member which attaches a cover body to a box-shaped body, as shown in FIG. As for the strength of the welded portion W (in other words, corresponding to the total horizontal cross-sectional area of the welded portion), as in the case of the bolt in the above-described embodiment, the fine metal wire 14 that cannot be detonated only by the discharge impact force. In order to explode (transfer) the nitromethane 16 at a position far from the nitromethane 16 near the metal thin wire 14 with the explosive force of the explosion, the nitromethane 16 is not leaked to the outside until the explosion reaction rate is sufficiently increased. It has strength (locking ability).

  Further, in the above-described embodiment, the nitromethane storage portion (also a cartridge portion) of the discharge shock destruction apparatus is configured by a bottomed box-shaped body and a lid that closes the opening of the box-shaped body. For example, you may comprise from the frame-shaped side wall body in which the space chamber was formed in the center, and a pair of cover body which block | closes both opening parts of this frame-shaped side wall body.

  That is, as shown in FIG. 11, the discharge impact destruction device 51 includes a frame-shaped side wall body 52 having a space chamber 52 a having a circular shape in plan view at the center, and a plurality of bar shapes on the frame-shaped side wall body 52. A pair of lids 55 that can be locked via bolts 53 and nuts 54 serving as locking members to close the openings on both sides, and disposed in a space chamber 52a formed inside the frame-shaped side wall 52. In addition, a thin metal wire 57 having both ends connected to one end side of a pair of electric wirings 56 connected to a power supply device (not shown), and nitromethane, which is an explosive substance filled in the space chamber 52a 58, and the frame-like side wall body 52 and the lid bodies 55 are made strong enough not to be damaged by the explosive force of the nitromethane 58 filled in the space chamber 52a. Also in this case, as in the above-described embodiment, the frame-like side wall body 52 and each lid body 55 are made of a metal material (an example of a conductive material) and are formed on the inner surface of each lid body 55. A plate-like protruding portion 55a is provided along the inner peripheral surface of the space chamber 52a, and a sheet-like insulating material 59 is disposed on the surface of each plate-like protruding portion 55a.

  In addition, in this discharge shock destruction apparatus 51, the same effect as that of the above-described discharge shock destruction apparatus 1 is obtained, and there is a space outside both lid bodies 55 when placed (inserted) in the destruction portion. In the case where the two lid bodies 55 are popped out, the both sides can be destroyed at the same time, so that the efficiency of the destruction work can be improved.

  Further, the engagement member between each lid body 55 and the frame-like side wall body 52 in the configuration shown in FIG. 11 is not a bolt but a weld W similar to that described with reference to FIG. 10 as shown in FIG. You may make it latch using.

  Moreover, about each modification shown in the said embodiment and FIGS. 9-12, although one thin metal wire was arrange | positioned in a space room, for example of the box-shaped body 11 or the frame-shaped side wall body 52 A plurality of, for example, two or three fine metal wires 14 and 57 may be arranged in the space chambers 11c and 52a, respectively.
