Description

The invention relates to anti-tank explosive barriers.

At present, anti-tank ditches are known that are torn off manually using earthmoving equipment, as well as explosive methods using concentrated and elongated charges (Manual on demolition work, M .: Military Publishing House, 1969, 464 pp.). The closest analogue to the claimed invention is the formation of an anti-tank ditch in advance of an explosive method with extended charges.

The disadvantage of the analogue design is that the charge cannot be removed from the charge after its incorporation if the charge was not used, and also that the anti-tank ditch is formed by the explosion in advance, regardless of whether the enemy will advance in this direction.

Disclosure of invention

The aim of the invention is to achieve a military-technical effect in the form of a trench, at the bottom of which there is a box-shaped structure for placing an elongated charge in the shell with a cable attached to its end to extract the latter in the absence of the need for its use, and the method, which consists in the fact that the explosion charge and the formation of an anti-tank ditch is made immediately before the appearance of tanks in front of the location of the anti-tank ditch.

The implementation of the invention

The proposed device (Fig. 1, 2) consists of a trench (1) designed to a given depth, a wooden box (2), an explosive charge (3), a charge shell (4), an action movie (5), an electric blast network (6) , a blasting station (7), a cable (8) attached to an elongated charge to extract a charge if necessary, clogging (9) with large pieces of soil. Device preparation sequence:

- a trench in the soil comes off to a width slightly larger than the width of a wooden box installed above the charge;

- an elongated charge is laid at the bottom of the trench with the fighter attached to the charge and an electric blast network is laid or a radio blast network is prepared;

- a wooden box is installed, the purpose of which is to provide the possibility of extracting an extended charge, if it will not be used;

- trenching is carried out in large pieces of soil.

The trench is camouflaged from above by plant soil and small shrubs.

The principle of operation is as follows. When tanks or other tracked, combat wheeled vehicles appear immediately before the trench from the blasting station, a current pulse is generated and an anti-tank moat is formed. Pieces of soil flying apart in an explosion injure the infantry when it appears. If the enemy’s tanks do not move in the direction of the site where the trench is located, then the charge installed in the trench box is removed and can be used to form anti-tank ditches in other tank hazardous directions.

An example of calculating the formation of an anti-tank ditch.

Calculation procedure according to the demolition manual. M .: Military Publishing, 1969.

Initial data

The visible depth of the moat is 1.75 m.

The width of the ditch at ground level is at least 6 m.

Determination of the weight of the elongated charge and its depth for the formation of an anti-tank ditch 100 m long in loam.

For loam:

explosive coefficient k = 1.0 kg / m ³ ;

coefficient a = 0.5;

p = 1.75 m is the visible depth of the moat;

.moat radius $$r=\frac{p}{a}=\frac{1.75}{0.5}=\mathrm{3,5}m$$

.

The width of the moat B = 2r = 2 × 3.5 = 7.0 m.

Let us take the explosion action index n = 2.0.

Charge depth

. $$h=\frac{z}{n}=\frac{\mathrm{3,5}}{2.0}=1.75m$$

.

Linear weight is determined by the formula

C _y = k · M _y · h ² = 1.0 · 2.59 · 1.75 ² = 7.95 kg / pm.

The total consumption of explosives per 100 m = 795 kg.

Scattering of pieces of soil (Zosk)

. $$Z\mathrm{about}\mathrm{from}\mathrm{to}=140\ast n\ast \sqrt{h}=140\ast 2\ast 1.32\approx 370m$$

.

Within these limits, defeat of the enemy’s manpower is possible.

Claims (1)

Equipment for the construction of an anti-tank ditch, including a subversive station, electric blasting network, a wooden box with an extended explosive charge in the shell located inside the box installed at the bottom of a pre-prepared trench with jamming, a cable attached to the shell, an action movie in an extended charge, characterized in that the elongated charge in the wooden box is made with the possibility of removal in the absence of the enemy in this direction and installation in another place.
