Description

A filling up type blasting kit for military disapproval facilities of road and tunnel}

The present invention relates to a full-color blasting kit for road and tunnel rejection facilities, and more specifically to effectively form a large fire on the road to prevent or delay the advance of enemy tanks and military vehicles, etc. Alternatively, it is possible to quickly and reliably cause a legal accident at the entrance of a tunnel, but it is easy to check for malfunctions in the usual time, and by using smoke bombs and light bulbs during training, it prevents the occurrence of safety accidents, and explodes similar to the actual situation. It relates to a full-color blasting kit for road and tunnel rejection facilities that has a structure for training.

In general, the conventional military road and tunnel rejection facilities are composed of vertical walls, blocking blocks, and block supports, and the vertical walls are installed to face both side ends of the road so that the upper side is formed with an inclined surface of about 45 ㅀ. The blocking block is a hexahedral block produced by pouring concrete, and is mounted on the upper surface of the vertical wall. At this time, the blocking block is positioned so that one surface portion coincides with the road side wall surface of the vertical wall.

That is, the blocking block is disposed on the vertical wall such that the center of gravity is biased toward the road, and the block support supports the inclined surface of the vertical wall and the lower surface of the blocking block so that the blocking block is maintained on the vertical wall. In the case of a conventional rejection facility having such a configuration, when an explosive is installed on the block support and then the block support is detonated when the road is closed in the exhibition, the blocking block in which the center of gravity is biased toward the road is tilted toward the road on the vertical wall. It falls down and closes the road between vertical walls.

However, such a conventional reject facility has an insignificant effect of blocking enemy vehicles and tanks due to the development of enemy equipment, and accidents such as block blocks falling due to unintentional damage to the block support due to the aging of the facility at ordinary times occur. There was a problem.

The present applicant has made various attempts and efforts to overcome the above-mentioned conventional problems, and as a result, when explosives are exploded in the exhibition, a large opening is formed on the ground without a separate blocking block, or there is a situation on the exit side of the tunnel. By developing and blocking the entrance of the tunnel, we developed a military-rejection facility for roads and tunnels that can fundamentally prevent the occurrence of blockade accidents due to aging of facilities such as block block falling accidents while reliably blocking the advancing of enemy forces.

The present invention relates to a bombing kit used in the military rejection facilities of the above roads and tunnels developed by the present applicant, and hereinafter, it should be noted that only the bombing kit is described herein.

Demolition kits used in military refusal facilities that could block the advancing of the enemy by forming a large airway on the road or blocking the tunnel entrance by creating a tunnel exit legal situation consisted of a single tube to simply bury the explosives underground. .

These short-tube-type blasting kits are relatively easy to charge when they are short, but they are more effective and form a large-sized crater, or blast them in order to bury the explosives deep into the ground to cause a large-scale legal situation. When the kit is designed to have a long length, it is very difficult to accurately load the explosives on the inner bottom surface of the explosives kit, and it is impossible to immediately check whether the explosives detonation circuit is correctly connected without error. There was no serious problem.

The present invention has been devised in consideration of the above problems, and its purpose is to effectively form a large fire exit on the road or tunnel entrance in order to prevent or slow down the advance of enemy tanks and military vehicles in the exhibition. It is possible to quickly and reliably cause a legal aberration, but it is easy to check for malfunctions during training, and during training, use smoke bombs rather than actual explosives to prevent the occurrence of safety accidents against blasting, Not only can we conduct similar blasting drills, but also create a powerful explosive force with the same amount of explosives. Is to provide.

The purpose of the nickname is to be installed on the blasting kit installation well formed by excavating the road or tunnel's entrance side, and if necessary, load the explosive and then blast the loaded explosive to form a crater on the road, or In the explosion kit used for roads and military denied facilities in tunnels to block the entrances of tunnels by causing a legal situation at the entrances of tunnels,

The blasting kit is a cylinder having an upper cap for opening and closing the opened upper portion, the outer protective box installed on the blasting kit installation well; An upper end portion of which is an open cylinder, the inner protective box being fitted into the outer protective box; It has an explosives charge part loaded with explosives at the lower part, a handle part rotatably mounted at the upper end, and a plurality of electrical detonators wired to connect the charged explosives and detonator, in the longitudinal direction inside the inner protective box. Explosive compartment built in detachably; A plurality of color-blocking blocks that are accommodated in a stacked manner on the upper side of the explosive charge compartment to amplify the explosive force of the loaded explosives; by a full-color detonation packet used in military rejection facilities of roads and tunnels. It can be achieved.

The full-color blasting kit used in military rejection facilities of roads and tunnels according to the present invention is composed of an outer protective box, an inner protective box, an explosive compartment and a plurality of color blocks, and the outer protective box is composed of multiple layers. And it is very easy to install on the tunnel's surface, but can effectively use the effective life of a pre-installed blasting kit, and blocks the upper side of the explosive with multiple color blocks, so that the explosive power is concentrated downward, so effective explosive power with less explosive In addition to being obtained, a variety of detonation vessels such as electric detonation vessels and flashing ships can be used depending on the situation, and the photovoltaic power generation unit and LED lighting can be used to quickly and easily load and detonate at night. Equipped with electric detonation unit and detonation status LED lighting provided in each detonation kit without loading. Since it is possible to perform training similar to the actual operation even during training without fear of occurrence of a safety accident, it has the effect of maintaining the best combat capability of allies.

The above configuration is such that the LED 400 'is turned on when the detonation device E1 is operated without the explosive charge, during detonation training using the detonation kit rather than the actual operation.

As an example of an explosion kit according to the present invention, as shown in the attached FIG. 14, the correlation part 112 is spaced at a predetermined interval along the outer circumferential surface of the upper end, and a plurality of hooks protruding outwardly obliquely toward one side ( 112c).

The upper cap 112-1 is spaced at a predetermined interval along the inner circumferential surface of the lower portion so as to be inclined toward one side so as to be engaged with respect to the engaging piece 112c of the correlated portion 112, so that the correlated portion 112 is formed. It may be configured to have a plurality of engaging pieces (112d) detachably engaged with the engaging piece (112c).

In the above-described configuration, the outer protective box 110 constituting the explosion kit 100 is electrically connected to the electric detonator C, and the detonator E1 according to the pressing operation of the upper cap 112c. Or it includes a detonation switch (SW) to detonate the explosives by energizing the power supplied from the storage battery (500).

The detonation switch (SW) is installed to be able to be push-operated between the correlation part (112) and the upper cap (112-1) in the exhibition, and automatically loads when a load over a certain size is applied to the upper cap (112c). It is configured to detonate the explosive (E) by being pressed.

The operation according to the installation and blasting of the full color type blasting kit 100 configured as described above will be described as follows.

The full-color blasting kit 100 according to the present invention forms an elongated pit-shaped blasting kit 1 from the ground to block the passage of roads and tunnels, and then protects the outer side of the blasting kit 100 It is seated, and inside it is loaded with an internal protection box (120), an explosive compartment (130) and an explosive (E).

The blasting kit 100, as shown in the attached Figure 11, is installed to protrude the upper upper portion of the blasting kit.

The blasting kit is installed by arranging a plurality of crossings as described above, first to guide the outer protective box 110 to the blasting kit installation well 1, and the inner protective box 120 in the outer protective box. Will guide you sequentially.

The explosion kit installer guides the explosive compartment 130 to the inner protector 120, but as shown in the attached FIG. 10, before guiding the explosive compartment to the bottom of the inner protector 120 Charge the explosive charge (E) formed in the explosive charge compartment (131) side compartment (131a) of the explosive compartment 130, and set the electric detonator (C) and the fire wire from the explosive with the explosive charge.

The electric detonator C and the drawing wire are respectively disposed in the vertical support 132 of the explosive compartment 130 and are routed through a fixed pipe.

When the above-described operation is completed, the explosion kit installer slowly guides the explosive compartment 130 in the inner protective box 120 while gripping the handle part 134 provided on the top side of the explosive compartment 130. Set it as possible.

The explosive compartment 130 placed as described above is the impact of the shock absorber B guided to the inner bottom of the lower tube 111 forming the outer protective box 110 and the lower inner bottom of the inner protective box 120. It is possible to place the explosive compartment 130 in a stable state by acting as a buffer so that no shock is applied to the explosive (E) by the absorption action.

Since the explosive compartment is placed as described above, the explosive charge can be loaded in the dark state by illuminating the explosive compartment 130A through the LED 400 'provided inside the explosive compartment.

When the explosive charge is completed, the explosive compartment is placed in the inner protection box. At this time, at the same time as the wiring of the electric detonator and the conductor, the one or more full color blocks are placed in the upper part of the explosive charge part 131. do.

Among the full color blocks, the full color block 140 adjacent to the upper side of the explosive compartment 130A selects and secures the full color block 140 provided with a conical liner 143 at the bottom inside.

The full-color block 140 having the liner 143 is for amplifying the explosion pressure when the explosive explosive (E) is exploded, and concentrates the explosion pressure downward rather than upward of the road where the explosive kit 100 is purchased, on the road. It is to be able to form the crater (2) as shown in Figure 15 when the blasting of the blasting kit 100 embedded in.

As described above, with the inside of the color block 140, the electric detonator C and the drawing wire are drawn out to the upper cap 112-1 side of the outer protective box 110 and connected to the detonator E1. As an electrical signal through 300, the explosion of the explosive is induced, and when the explosive explosive (E) explodes, the lower portion 111 of the outer protective box 110 is first ruptured by a plurality of formed through holes 111b. When this occurs, the liner 143 has a Neumann effect on the explosion pressure.

At this time, the colorant material 142 inside the colorant block 140 serves to minimize upward explosion of the liner.

The explosion of the explosive is to simultaneously explode at the same time through the detonation device to explode each explosive kit, and during the training rather than the exhibition, explosive training can be performed without loading the explosive.

It is possible to check whether the explosion kit is exploded or not depending on whether the LED 400 'is lit when the detonator E1 is operated without loading explosives during ground training, which is the upper surface of the upper cap of the outer protective box 110. The detachably installed LED is energized with the power distribution unit 100-1, and whether or not it is possible to perform an explosion training similar to the actual operation by simply lighting the LED.

The training as described above facilitates the malfunction check during normal times, and during the training, smoke bombs can be used to prevent the occurrence of safety accidents, while conducting blasting training close to the actual situation.

The power supply of the blasting kit 100 as described above accumulates the electrical energy collected in the solar panel 200 in the storage battery 500 through the inverter 300, and then the electric detonator C and the detonating device through the inverter. Explosives (E) can be exploded or drilled through (E1).

On the other hand, the blasting kit according to the present invention can be blasted directly through the detonation device as described above, but as shown in the attached Figure 14

Combining a plurality of engaging pieces 112d detachably engaged with the engaging pieces 112c along the inner circumferential surface of the lower end of the upper cap 112-1 with respect to the plurality of engaging pieces 112c formed in the correlation part 112 And, the inside of the upper cap (112c) by placing a detonation switch (SW) can be operated in the form of detonating the explosives through the detonation switch when a pressing pressure of a predetermined size or more is applied to the upper cap.

This can be used as a form in which the blasting kit is completely buried from the ground, and the blasting kit is installed on the road with the top cap portion covered with soil and disguised.

This is to prevent the enemy from advancing by detonating the enemy by forming a crater, or exploding the explosive kit as the pressure of the tank, the wheel of the military vehicle, and the upper cap directly when the traffic of the tank or military vehicle is on the exhibition. It has the effect of delaying.
