Abstract

A mine for blocking roads is formed by an explosive charge (3) arranged on the rear side of a crash barrier (1). The gutter-shaped recess (4) of the crash barrier (1) thus forms for the explosive charge (3) a covering which is deformed into a projectile when the charge (3) is detonated.

Description

Die Erfindung bezieht sich auf eine Mine zum Sperren von Straßen.The invention relates to a mine for blocking roads.

Herkömmliche Minen, die zum Sperren von Gelände- und Straßenabschnitten verwendet werden, sind, bedingt durch Formgebung, Anstrich usw. als Waffe erkennbar und daher verhältnismäßig leicht zu entdecken. Eine Ausnahme bilden eingegrabene Minen, die jedoch zum Sperren von Straßen nur bedingt geeignet sind. Sind Minen einmal geortet, können Räummaßnahmen gezielt angesetzt werden.Conventional mines, which are used to block off sections of terrain and roads, are recognizable as a weapon due to their shape, paint, etc. and are therefore relatively easy to detect. Buried mines are an exception, but they are only of limited use for blocking roads. Once mines have been located, clearing measures can be targeted.

Aufgabe der Erfindung ist es, eine einfach aufgebaute und kostengünstig herzustellende, äußerlich nicht erkennbare Mine zum Sperren von Straßen bereitzustellen.The object of the invention is to provide a simply constructed and inexpensive to produce, externally undetectable mine for blocking roads.

Dies wird erfindungsgemäß durch die im Anspruch 1 gekennzeichnete Mine erreicht. In den Unteransprüchen sind vorteilhafte Ausgestaltungen der erfindungsgemäßen Mine gekennzeichnet.This is achieved according to the invention by the mine characterized in claim 1. Advantageous refinements of the mine according to the invention are characterized in the subclaims.

Herkömmliche Leitplanken bestehen aus Profilstahlblech mit einer Wandstärke von im allgemeinen 1 bis 3 mm. Stahlblech mit einer solchen Wandstärke ist zur Bildung von Projektilen bestens geeignet.Conventional guardrails are made of profiled steel sheet with a wall thickness of generally 1 to 3 mm. Steel sheet with such a wall thickness is ideally suited for the formation of projectiles.

Weiterhin erstrecken sich diese Leitplanken heutzutage entlang des Straßenrandes fast aller Straßen, insbesondere an allen Kurven, Böschungen und dgl. Stellen, die beim Abkommen eines Fahrzeugs von der Fahrbahn zu schweren Unfällen führen können. Dies gilt vor allem für Schnellstraßen, weshalb die Autobahnen praktisch vollständig mit Leitplanken ausgestattet sind, und zwar auch der Mittelstreifen. Die erfindungsgemäße Mine ist damit also an allen Straßen einsetzbar.Furthermore, these crash barriers nowadays extend along the roadside of almost all roads, in particular on all bends, embankments and the like, which can lead to serious accidents when a vehicle comes off the road. This applies above all to expressways, which is why the motorways are practically fully equipped with guard rails, including the median. The mine according to the invention can thus be used on all roads.

Dabei ist die erfindungsgemäße, an der Rückseite einer herkömmlichen Leitplanke angebrachte Mine als Waffe nicht erkennbar, so daß der Gegner auf sie auch keine Räummaßnahmen ansetzen kann, wodurch die Bedrohung erhalten bleibt.The mine according to the invention, which is attached to the rear of a conventional guardrail, is not recognizable as a weapon, so that the opponent cannot take any clearing measures on it, as a result of which the threat is retained.

Die erfindungsgemäße Mine ist darüber hinaus außerordentlich kostengünstig. Denn im einfachsten Fall umfaßt sie im wesentlichen nur die Sprengladung, den Zünder und Befestigungsmittel zum Befestigen der Ladung an der Rückseite der Leitplanke.The mine according to the invention is also extremely inexpensive. In the simplest case, it essentially only comprises the explosive charge, the detonator and fastening means for fastening the charge to the rear of the guardrail.

Die erfindungsgemäße Mine kann nachträglich an einer bereits vorhandenen, am Straßenrand fest installierten Leitplanke angebracht werden. Auch ist es möglich, Leitplankenteile erfindungsgemäß mit einer Sprengladung zu versehen und im Bedarfsfall gegen einen Teil einer am Straßenrand bereits vorhandenen Leitplanke auszutauschen.The mine according to the invention can be retrofitted to an existing guardrail that is permanently installed at the roadside. It is also possible, according to the invention, to provide crash barrier parts with an explosive charge and, if necessary, to replace them with part of a crash barrier already present on the roadside.

Das Profil üblicher Leitplanken, d. h. die rinnenförmige, im Querschnitt meist hutförmige Vertiefung oder Sicke, die sich in Längsrichtung entlang der Leitplanke erstreckt, wird dabei erfindungsgemäß ohne jede Änderung als Belegung genutzt.The profile of conventional guardrails, ie the channel-shaped depression or bead which is mostly hat-shaped in cross-section and extends in the longitudinal direction along the guardrail, is used according to the invention without any change as occupancy.

An dieser rinnenförmigen Vertiefung der Leitplanke wird dann eine einfache gepresste, gegossene oder sonst wie geformte Sprengladung befestigt und im Bedarfsfall von Hand über Kabel und elektrischen Zündimpuls (Batterie, Generator) oder mit geeigneten Zielerkennungssensoren gezündet.A simple pressed, cast or otherwise shaped explosive charge is then attached to this channel-shaped depression of the guardrail and, if necessary, ignited by hand using a cable and electrical ignition pulse (battery, generator) or with suitable target detection sensors.

Der Bereich der rinnenförmigen Vertiefung, an dem die Sprengladung angebracht ist, wird damit bei Detonation der Sprengladung zu eine im wesentlichen zusammenhängenden, geschoßartigen Körper oder Projektil verformt, welches mit hoher Energie in Richtung auf das zu bekämpfende Ziel auf der Straße abgeschleudert wird und darauf mit einer hohen Durchschlagsleistung auftrifft.The area of the channel-shaped depression to which the explosive charge is attached is thus deformed when the explosive charge is detonated to form an essentially coherent, projectile-like body or projectile, which is thrown off with high energy in the direction of the target to be combated on the road and with it a high penetration rate.

Wenn die Sprengladung im Querschnitt kreisförmig, quadratisch oder prismenförmig ausgebildet ist, wird ein bolzenförmiges Projektil mit besonders hoher Durchschlagsleistung erhalten, welches sich insbesondere zur Bekämpfung von gepanzerten Fahrzeugen eignet. Um die Trefferwahrscheinlichkeit zu erhöhen, können, wenn ein einfacher Zielerkennungssensor, z. B. eine Lichtschranke, verwendet wird, mehrere derartige, im Abstand voneinander angeordnete projektilbildende Ladungen gleichzeitig gezündet werden.If the explosive charge is circular, square or prismatic in cross section, a bolt-shaped projectile with a particularly high penetration rate is obtained, which is particularly suitable for combating armored vehicles. To increase the probability of a hit, if a simple target detection sensor, e.g. B. a light barrier is used, several such, spaced apart projectile-forming charges are ignited simultaneously.

Zur Bekämpfung nicht oder nur leicht gepanzerter Fahrzeuge sowie von Weichzielen ist es besonders vorteilhaft, sich entlang der Leitplanke erstreckende Sprengladungen von z. B. mehreren Metern Länge anzubringen. Dadurch wird ein entsprechend langes Schneidladungsprojektil gebildet, so daß auch bei Verwendung einfacher Sensoren, z. B. eines Richtmikrofons eine hohe Trefferwahrscheinlichkeit erreicht wird. Bei der Ausbildung der erfindungsgemäßen Mine als Schneidladung wird ein eher kostengünstiger Hochbrisanzsprengstoff, wie Hexogen, vorgezogen.To combat not or only lightly armored vehicles and soft targets, it is particularly advantageous to extend explosive charges of z. B. to attach several meters in length. This makes a correspondingly long one Cutting charge projectile formed so that even when using simple sensors, for. B. a directional microphone a high hit probability is achieved. When designing the mine according to the invention as a cutting charge, a rather inexpensive high-explosive, such as hexogen, is preferred.

Auch können ggfs. Schneidladungen und bolzenförmige Projektile bildende Ladungen im Abstand voneinander entlang der Leitplanke angebracht werden, um sowohl gepanzerte wie ungepanzerte Ziele optimal bekämpfen zu können.If necessary, cutting charges and charges forming bolt-shaped projectiles can be placed at a distance from one another along the guardrail in order to be able to optimally combat both armored and unarmored targets.

Durch die Detonation der Sprengladung wird allerdings die Leitplanke an der Stelle, an der die Sprengladung angebracht war, seitlich in Leitplankenlängsrichtung aufgerissen. Der Abstand, mit dem die Sprengladungen voneinander entlang der Leitplanke angeordnet werden, muß daher größer sein als der Bereich, an dem die Leitplanke aufgerissen bzw. zerstört wird. D. h., der Mindestabstand der Ladungen ist abhängig von der Größe der Ladung und dem damit verbundenen Zerstörungsumfang an der Leitplanke bei Detonation einer Ladung.Due to the detonation of the explosive charge, however, the guardrail at the point at which the explosive charge was attached is torn open laterally in the longitudinal direction of the guardrail. The distance at which the explosive charges are arranged from one another along the guardrail must therefore be greater than the area at which the guardrail is torn open or destroyed. This means that the minimum distance between the loads depends on the size of the load and the associated extent of destruction on the guardrail when a load detonates.

Nachstehend ist eine Ausführungsform der erfindungsgemäßen Mine anhand der Zeichnung näher erläutert, welche einen Querschnitt durch eine Leitplanke mit der Mine zeigt.An embodiment of the mine according to the invention is explained in more detail below with reference to the drawing, which shows a cross section through a guardrail with the mine.

Danach ist an der Rückseite einer Leitplanke 1 in einem Gehäuse 2 eine Sprengladung 3 angeordnet. Die rinnenförmige, im Querschnitt etwa hutförmige Vertiefung 4 der Leitplanke 1 bildet die Belegung in dem entsprechend geformten Hohlraum 5 der Sprengladung 3.An explosive charge 3 is then arranged on the rear of a guardrail 1 in a housing 2. The channel-shaped depression 4 of the guardrail 1, which is approximately hat-shaped in cross section, forms the occupancy in the correspondingly shaped cavity 5 of the explosive charge 3.

Das Gehäuse 2 weist, was in der Zeichnung nicht dargestellt ist, oberhalb und unterhalb der Vertiefung 4 Abwinklungen oder Flansche 6 auf, mit denen das Gehäuse 2 bzw. die Ladung 3 z. B. mit einem Kleber beiderseits der Vertiefung 4 an der Leitplanke 1 befestigt ist. Die Sprengladung 3 ist ferner an ihrer Rückseite mit einem Zünder 7 versehen, an den ein Zündkabel 8 angeschlossen ist, das an seinem der Leitplanke 1 zugewandten Ende zu einem Zielerkennungssensor 9 führt.The housing 2, which is not shown in the drawing, above and below the recess 4 bends or flanges 6, with which the housing 2 or the load 3 z. B. is attached to the guardrail 1 with an adhesive on both sides of the recess 4. The explosive charge 3 is also provided on its rear side with an igniter 7, to which an ignition cable 8 is connected, which leads to a target detection sensor 9 at its end facing the guardrail 1.

Der Zielerkennungssensor 9 ist in einem vorgegebenen Abstand von der Sprengladung 3 an der Rückseite der Leitplanke 1 angebracht. Der Sensor 9 kann dabei eine oder mehrere Sprengladungen betätigen.The target detection sensor 9 is attached to the rear of the guardrail 1 at a predetermined distance from the explosive charge 3. The sensor 9 can actuate one or more explosive charges.
