Description

Domaine de l'inventionField of the invention

La présente invention se rapporte à la destruction d'objets dangereux comme par exemple des obus ou autres munitions. L'invention concerne en particulier le domaine de la démilitarisation et plus généralement tous les secteurs de la protection de l'environnement. Elle se rapporte en particulier à un dispositif sécurisé de préparation pour destruction par explosion confinée d'objets dangereux ainsi qu'au procédé de réalisation et de mise en oeuvre d'un tel dispositif.The present invention relates to the destruction of dangerous objects such as shells or other ammunition. The invention relates in particular to the field of demilitarization and more generally to all sectors of environmental protection. It relates in particular to a secure preparation device for destruction by confined explosion of dangerous objects and the method of producing and implementing such a device.

Arrière plan technologiqueTechnological background

Chaque année, il est découvert 30 à 50 tonnes de munitions chimiques dans les anciens champs de batailles Français, notamment dans l'est et le nord de la France.Each year, 30 to 50 tons of chemical munitions are discovered in the old French battlefields, particularly in eastern and northern France.

Environ 60 000 000 obus toxiques ont été tirés sur les champs de batailles du nord-est de la France. 10 to 15% d'entre eux n'ont pas fonctionnés, soit à peu prés 100 000 tonnes... Bien que beaucoup de ces munitions aient déjà été retrouvées depuis la fin des conflits européens, le rythme des découvertes devrait rester constant pour les prochains siècles. C'est aussi le cas des régions du monde où de telles armes ont été utilisées ou stockées. La destruction et la neutralisation de tels objets posent de redoutables problèmes techniques.About 60 000 000 toxic shells were fired on the battlefields of north-eastern France. 10 to 15% of them have not worked, that is to say about 100,000 tons ... Although many of these munitions have already been found since the end of European conflicts, the pace of discoveries should remain constant for next centuries. This is also the case for regions of the world where such weapons have been used or stored. The destruction and neutralization of such objects pose formidable technical problems.

La destruction de produits toxique doit se faire nécessairement en en milieu fermé pour éviter la dissémination des molécules toxiques et de leurs produits de dégradation souvent eux même très dangereux (l'arsenic par exemple). La présence simultanée de la charge explosive et des produits toxiques rend les opérations de neutralisation délicates et dangereuses. La difficulté est à son comble lorsque les munitions en question sont dans un état qui ne permet pas leur démontage, soit du fait de leur corrosion, soit parce que leur système de mise à feu est déjà aligné c'est à dire armé et déclenché.The destruction of toxic products must necessarily be done in a closed environment to prevent the spread of toxic molecules and their degradation products often themselves very dangerous (arsenic for example). The simultaneous presence of the explosive charge and the toxic products makes the delicate and dangerous neutralization operations. The difficulty is at its height when the munitions in question are in a state that does not allow their disassembly, either because of their corrosion, or because their firing system is already aligned ie armed and triggered.

Un dispositif de destruction d'objets dangereux comme des obus, munitions ou autres charges à détruire par détonation comportant un emballage est connu du JP 2006 029608 A .A device for destroying dangerous objects such as shells, ammunition or other charges to be destroyed by detonation containing a package is known to JP 2006 029608 A .

Plusieurs technique de neutralisation ont été mises en oeuvre au cours du temps : perçage ou sciage télécommandé, dissolution acide, auto détonation en four blindé.Several neutralization techniques have been implemented over time: remote-controlled drilling or sawing, acid dissolution, self-detonation in an armored furnace.

L'une des méthodes les plus efficaces et les plus versatiles consiste à entourer la munition avec des charges explosives massives et à faire détoner l'ensemble dans une chambre de détonation blindée. La chaleur et l'onde de choc fracture la munition et détruisent son contenu explosif et/ou toxique.One of the most effective and versatile methods is to surround the munition with massive explosive charges and detonate the whole thing in an armored detonation chamber. The heat and the shock wave fracture the ammunition and destroy its explosive and / or toxic contents.

L'inconvénient majeur de la méthode réside dans le grand nombre d'opérations manuelles nécessaires : préparation de la munition et des charges additionnelles, mise en place de la ligne d'allumage, chargement de la chambre, ces opérations devant se faire le plus souvent en tenue de protection.The major drawback of the method lies in the large number of manual operations required: preparation of the ammunition and additional charges, setting up the ignition line, loading the chamber, these operations must be done most often in protective clothing.

Description détaillée de modes de réalisation de l'inventionDETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

Pour réduire voir supprimer les opérations manuelles de manipulation des munitions ou charges à détruire, la présente invention propose la constitution d'un moyen de conditionnement pré-équipé comportant des charges explosives et une ligne d'allumage. La ou les charges à détruire peut alors être déposée sur ce moyen qui, par une opération télécommandée simple vient constituer un colis à introduire dans une chambre de détonation pour le faire exploser.To reduce or eliminate the manual handling operations of the ammunition or charges to be destroyed, the present invention proposes the constitution of a pre-equipped conditioning means comprising explosive charges and an ignition line. The charge or charges to be destroyed can then be deposited on this means which, by a simple remote control operation comes to constitute a package to be introduced into a detonation chamber to explode.

Un avantage de l'invention est que les charges explosives et la ligne d'allumage étant des objets pyrotechniques neufs, elles peuvent être manipulées directement par un opérateur en conformité avec les normes de sécurité et notamment le respect des quantités maximales d'explosif présent.An advantage of the invention is that the explosive charges and the ignition line being new pyrotechnic objects, they can be handled directly by an operator in accordance with the safety standards and in particular compliance with the maximum quantities of explosive present.

Le moyen de conditionnement pré équipé de l'invention réalise en particulier les fonctions suivantes :

  • permettre le pré-positionnement des charges explosives et de la ligne d'allumage;
  • plaquer les charges explosives sur la munition afin de la fracturer;
  • présenter une interface de manutention aisément tété-opérable du colis final;
  • être compatible des contraintes industrielles : faible coût, facilité de stockage et d'approvisionnement.
The pre-equipped conditioning means of the invention performs in particular the following functions:
  • allow the pre-positioning of the explosive charges and the ignition line;
  • lay explosive charges on the ammunition to fracture it;
  • to present an interface of handling easily tété-operable of the final package;
  • be compatible with industrial constraints: low cost, easy storage and supply.

La figure 1 représente un exemple de réalisation d'un dispositif selon l'invention avant pliage. Sur un flan 10, par exemple une plaque de carton d'emballage épais standard, sont collés des blocs de mousse 40, 41.The figure 1 represents an embodiment of a device according to the invention before folding. On a blank 10, for example a standard thick packing cardboard plate, blocks of foam 40, 41 are glued.

Le flan peut notamment être un carton fort pour emballage d'épaisseur 10 mm à triple cannelure dont la fibre principale (l'axe des cannelures) est positionné perpendiculairement à l'axe des munitions pour éviter un fléchissement du colis une fois replié. Pour permettre son pliage, le flan peut comporter des empreintes de lignes de pliage.The blank may in particular be a strong carton for 10 mm thick triple-groove packaging whose main fiber (the axis of the grooves) is positioned perpendicular to the axis of the ammunition to prevent sagging of the package once folded. To allow its folding, the blank may include imprints of fold lines.

Les plaques de mousse 40, 41 sont par exemple des plaques de mousse polymère telle qu'une mousse polyuréthane standard de type 48 kg/m3 pour la plaque supportant la munition, 24 kg/m3 pour les autres pans de l'emballage déplié. Les plaques de mousse sont simplement collées (par des bandes autocollante ou une colle en bombe par exemple) sur le carton de l'emballage.The foam plates 40, 41 are, for example, polymer foam plates such as a standard polyurethane foam of 48 kg / m 3 type for the plate supporting the ammunition, 24 kg / m 3 for the other parts of the unfolded packaging. The foam boards are simply glued (by self-adhesive strips or a spray glue for example) onto the carton of the package.

Le flan peut être déposé sur un plateau support de type plaque polyacrylate d'épaisseur 16 mm et de largeur 60 mm.The blank can be deposited on a polyacrylate plate-type support plate with a thickness of 16 mm and a width of 60 mm.

Des pains d'explosif formant les charges explosives 20, 21 sont fixés sur les plaques support telles que des blocs de mousse à l'aide de moyens de fixation des charges explosives de type petites sangles 50 pourvues préférentiellement de moyens auto-agrippant mais pouvant aussi être élastiques. Typiquement les charges explosives sont des charges explosives utilisées en mines et carrières par exemple de type émulsion.Blocks of explosive forming the explosive charges 20, 21 are fixed on the support plates such as foam blocks using means for fixing the explosive charges of small straps type 50 preferably provided with self-gripping means but also to be elastic. Typically explosive charges are explosive charges used in mines and quarries, for example emulsion type.

Le flan comporte des lignes de pliage p1, p2, p3, p4 définissant des pans 11, 12, 13, 14a, 14b et la charge à détruire, ici un obus 100 qui est posée sur les charges explosives disposées sur un pan principal 11 du dispositif autour duquel le flan sera replié.The blank comprises fold lines p1, p2, p3, p4 defining sections 11, 12, 13, 14a, 14b and the load to be destroyed, here a shell 100 which is placed on the explosive charges arranged on a main section 11 of the device around which the blank will be folded.

La figure 2 représente le flan équipé des plaques support 40, 41 sans les charges explosives. Le pan principal 11 et sa plaque support 40 est plus large que les pans latéraux 12, 13 et que les pans extrêmes 14b, 14c destinés à réaliser la face supérieure de l'emballage. Ces pans latéraux et extrêmes reçoivent des plaques de largeur réduite 41. Les plaques 40, 41 reçues par les pans sont découpés pour avoir une largeur réduite par rapport aux pans pour permettre le pliage de l'emballage en forme de boîte tubulaire.The figure 2 represents the blank equipped with the support plates 40, 41 without the explosive charges. The main panel 11 and its support plate 40 is wider than the side panels 12, 13 and the end panels 14b, 14c intended to provide the upper face of the package. These side and end panels receive plates of reduced width 41. The plates 40, 41 received by the panels are cut to have a reduced width relative to the panels to allow the folding of the box-shaped packaging.

Les moyens 50 de fixation des charges explosives de type sangles, par exemple en deux parties munies en matériau auto agrippant (connu par exemple sous la marque Velcro) ou élastiques, sont montés sur le flan et traversent des fentes dans les plaques support.The means 50 for fixing the explosive charges of the straps type, for example in two parts provided with self-gripping material (known for example under the trademark Velcro) or elastic, are mounted on the blank and pass through slots in the support plates.

Le dispositif comporte en outre une la ligne d'allumage 60 qui est un dispositif standard constitué d'un détonateur électrique 61 ou initiateur et d'une charge détonante 62 ou booster. Cette ligne d'allumage est chargée d'allumer simultanément toutes les charges additionnelles 20, 21. L'initiateur et la charge détonante sont placés à l'une des extrémités de la boîte, là où l'action de compression des blocs de mousse va presser les pains d'explosifs contre eux. Un fil électrique 63 reliant le détonateur à un module de commande 64 est replié sur un des flancs de la boîte et maintenu par des attaches par exemple des sangles en matériau auto-agrippant. Le module de commande 64 relié à l'initiateur par le fil 63 peut ainsi être éloigné de la boîte.The device further comprises an ignition line 60 which is a standard device consisting of an electric detonator 61 or initiator and a detonating charge 62 or booster. This ignition line is responsible for simultaneously igniting all additional charges 20, 21. The initiator and the detonating charge are placed at one end of the box, where the compression action of the foam blocks goes squeeze the loaves of explosives against them. An electrical wire 63 connecting the detonator to a control module 64 is folded onto one of the sidewalls of the box and held by fasteners, for example straps made of self-gripping material. The control module 64 connected to the initiator by the wire 63 can thus be moved away from the box.

La mise en place des charges explosives telles que des pains d'explosifs, ainsi que la mise place de la ligne d'allumage peut se faire de manière manuelle dans un local ad hoc sur la plaque équipée des plaques support et des charges explosives. Une fois la plaque ainsi préparée, elle est transférée dans un local réservé aux opérations impliquant la manipulation des charges à détruire. Là la dangerosité des opérations impose la télémanipulation.The emplacement of the explosive charges such as explosive bars, as well as the setting of the ignition line can be done manually in an ad hoc room on the plate equipped with support plates and explosive charges. Once the plate thus prepared, it is transferred to a room dedicated to operations involving the handling of the loads to be destroyed. There the dangerousness of the operations imposes the remote handling.

Les plaques de mousse 40, 41 et charges explosives 20, 21 sont disposés de telle manière qu'ils présentent un creux permettant une dépose stable et télé-opérée de la charge à détruire. La ou les munitions à détruire sont prélevées du stock et déposées sur les charges explosives du flan principal. Le dispositif est alors refermée par une machine de type plieuse. La fermeture du colis que constitue l'emballage équipé de ses charges explosives et renfermant l'objet dangereux à détruire est par exemple assurée par une bande adhésive.The foam plates 40, 41 and explosive charges 20, 21 are arranged in such a way that they have a recess allowing a stable and teleoperated removal of the charge to be destroyed. The ammunition (s) to be destroyed are taken from the stock and deposited on the explosive charges of the main blank. The device is then closed by a folding machine. Closing the package that is the packaging equipped with its explosive charges and containing the dangerous object to be destroyed is for example provided by an adhesive tape.

Les étapes du procédé de mise en oeuvre du dispositif de l'invention sont schématisées en figure 3 et comprennent:

  • étape A: pose du flan de réception de munitions déplié et muni de ses plaques support qui ici comportent des découpes latérales à 45° pour permettre le pliage du flan selon ses lignes de pliage ;
  • étape B: mise en place des charges explosives selon un arrangement de charges épaisses 20 et fines 21 assurant une bonne couverture de la charge à détruire une fois le colis replié puis mise en place d'une ligne d'allumage;
  • étape C: dépose de la ou des munitions ou charges à détruire sur le pan autour duquel sera replié le colis;
  • étapes D, E, F: fermeture progressive du colis selon les lignes de pliage p2, p3 pour replier les pans latéraux 12, 13 autour du pan principal 11 puis p1, p4 pour replier les demi pans supérieurs 14a, 14b;
The steps of the method of implementation of the device of the invention are schematized in figure 3 and include:
  • step A: laying the ammunition receiving blank unfolded and provided with its support plates which here have 45 ° side cutouts to allow the folding of the blank according to its fold lines;
  • step B: placing explosive charges according to a thick and thin charge arrangement 21 ensuring good coverage of the charge to be destroyed once the package folded and then set up an ignition line;
  • step C: removal of the ammunition or charges to be destroyed on the pan around which the package will be folded;
  • steps D, E, F: progressive closure of the package according to fold lines p2, p3 to fold the side panels 12, 13 around the main panel 11 then p1, p4 to fold the upper half panels 14a, 14b;

Dans le colis replié selon l'étape F les plaques de mousse appliquent fermement les charges explosives sur la charge à détruire.In the package folded according to step F the foam plates firmly apply the explosive charges to the load to be destroyed.

Le colis terminé est réalisé sous forme d'une boîte tubulaire, ici de section carrée ou rectangulaire représentée en figure 4 avec des sangles de manutention 51 par exemple préalablement fixées sous le flan de sorte que leur décrochage et la mise en place de ces soit possible avec un seul mouvement;The finished package is made in the form of a tubular box, here of square or rectangular section represented in figure 4 with handling straps 51 for example previously fixed under the blank so that their stall and the introduction of these is possible with a single movement;

La suite du processus comporte l'accrochage de la boîte ou colis à un engin de manutention au moyen des sangles 51 et la mise en place de la boîte dans une chambre de détonation 70 comme représenté en figure 5 par l'engin de manutention qui peut être un robot piloté à distance.The following process involves the attachment of the box or package to a handling machine by means of the straps 51 and the establishment of the box in a detonation chamber 70 as shown in FIG. figure 5 by the handling machine which can be a remotely controlled robot.

Ensuite il est procédé à la détonation de la boîte.Then it is detonated the box.

L'ensemble des matériaux choisis répond à deux exigences: un coût minimum, compte tenu que la boîte est à usage unique, et une réduction du volume gazeux émis lors de la combustion de la boîte dans la chambre. Cette dernière exigence correspond en général à la définition d'une masse maximale admissible et un contenu en matière organique maximal.The set of selected materials meets two requirements: a minimum cost, considering that the box is for single use, and a reduction in the gaseous volume emitted during the combustion of the box in the room. This latter requirement generally corresponds to the definition of a maximum permissible mass and a maximum organic matter content.

La découpe des blocs de mousse est adaptée à la forme et au poids des munitions. Les exemples des figures 6A à 6G donnent un aperçu non limitatif des arrangements possibles pour:

  • dans le cas de la figue 6A, trois petites munitions 102, une boîte à quatre pans et rabat 15 et des blocs de mousse 40, 41, 42 de trois largeur différentes;
  • les figures 6B et 6C, deux arrangements possibles pour deux munitions moyennes 101. L'arrangement de la figure 6B correspond à une boîte formée selon quatre plis p1, p2, p3, p4 avec deux demi pans 14a, 14b en face supérieure, l'arrangement de la figure 6C correspond à une boîte formée selon trois plis p1, p2, p3 avec un pan 14 en face supérieure plié à partir d'une première face latérale 12 et rejoignant seconde une face latérale 13. Cette boîte comporte en outre une plaque mousse inférieure munie d'une découpe 44 permettant d'enfoncer une charge explosive 20 et ainsi de rapprocher les charges à détruire;
  • les figures 6D et 6E deux arrangements réalisés pour des grosses munitions 103, l'arrangement de la figure 6D plaçant des charges épaisses 20 aux coins de la boîte alors que l'arrangement de la figure 6E les place sur des faces latérales enfoncées dans des découpes des plaques latérales;
  • les figures 6F et 6G des arrangements aussi destinés à des grosses munitions 103 qui prévoient des arrangements de charges explosives épaisses 20 et fines 21 permettant de répondre à diverses situations selon la solidité de la charge à détruire.
The cutting of the foam blocks is adapted to the shape and weight of the ammunition. Examples of Figures 6A to 6G give a non-limiting overview of the possible arrangements for:
  • in the case of Fig. 6A, three small munitions 102, a box with four sides and flap 15 and foam blocks 40, 41, 42 of three different widths;
  • the Figures 6B and 6C , two possible arrangements for two medium ammunition 101. The arrangement of the Figure 6B corresponds to a box formed in four folds p1, p2, p3, p4 with two half-panels 14a, 14b on the upper face, the arrangement of the Figure 6C corresponds to a box formed in three plies p1, p2, p3 with a pan 14 on the upper face folded from a first lateral face 12 and secondly joining a lateral face 13. This box further comprises a lower foam plate provided with a cutout 44 for driving an explosive charge 20 and thus to bring the charges to be destroyed;
  • the Figures 6D and 6E two arrangements made for large ammunition 103, the arrangement of the Figure 6D placing thick charges 20 at the corners of the box while the arrangement of the figure 6E places them on side faces sunk into cutouts of the side plates;
  • the Figures 6F and 6G arrangements also for large munitions 103 which provide arrangements of thick and thin explosive charges 21 for responding to various situations depending on the strength of the charge to be destroyed.

Le dispositif de l'invention peut évoluer notamment au niveau de l'utilisation de blocs de mousse de densité différente pour éviter l'écrasement du au poids de la munition, une définition des dimensions de boîte correspondant aux divers calibres, avec des boîtes compatible de 2 ou 3 munitions pour les petits calibres, l'utilisation de sangles repliées au long de la boîte pour permettre leur saisie et déploiement par un robot manipulateur, l'utilisation d'un système de connexion de la ligne d'allumage 60, la possibilité de pouvoir introduire simultanément plusieurs boîtes dans une chambre de détonation en utilisant un plateau porte boîte, plaque de plastique acrylate alvéolée par exemple. Dans ce cas une ligne d'allumage commune à toutes les boîtes et fixée sur le plateau peut être utilisée.The device of the invention can evolve especially in the use of foam blocks of different density to avoid crushing by the weight of the ammunition, a definition of the box dimensions corresponding to the various calibers, with compatible boxes of 2 or 3 ammunition for small calibres, the use of straps folded along the box to allow their capture and deployment by a manipulator robot, the use of a connection system of the ignition line 60, the possibility of being able to simultaneously introduce several boxes in a detonation chamber using a tray holder box, plate of plastic acrylate alveolée for example. In this case an ignition line common to all boxes and fixed on the tray can be used.

L'exemple de la figure 7A est une variante pour laquelle le flan 10' est directement réalisé en mousse et muni de découpes entre les pans sous forme de rainures en V 16 adaptées réaliser des zones d'épaisseur réduite permettant de plier le flan selon quatre pans pour réaliser le colis tubulaire selon la figure 7B .The example of Figure 7A is a variant for which the blank 10 'is directly made of foam and provided with cutouts between the sections in the form of V-shaped grooves 16 adapted to achieve areas of reduced thickness for folding the blank according to four sections to produce the tubular package according to the Figure 7B .

Dans cet exemple, les moyens 50 de fixation des charges sont constitués par des sangles insérées dans des fentes de la mousse et se refermant sur les charges explosives.In this example, the means 50 for fixing the loads are constituted by straps inserted in slots of the foam and closing on the explosive charges.

L'exemple des figures 7A et 7B comporte une plaque support 55 qui peut aussi être utilisée dans le cas de l'exemple de la figure 1 et qui peut notamment comporter des moyens de retenue des sangles de manutention.The example of Figures 7A and 7B comprises a support plate 55 which can also be used in the case of the example of the figure 1 and which may include means for retaining the handling straps.

La figure 8 représente un emballage de section polygonale ici hexagonale comportant des pans 11a à 11e de dimension identiques, Dans cet exemple les pans sont réalisés directement dans le flan en mousse pourvu de rainures en V 16 de pliage comme le flan de la figure 7A. Un tel flan est réalisé dans une mousse suffisamment dense pour se passer d'un flan en carton sur lequel sont disposées des plaques de mousse.The figure 8 represents a polygonal section packaging here hexagonal having identical 11a to 11e sections, In this example the sections are made directly in the foam blank provided with folding V 16 grooves such as the blank of the Figure 7A . Such a blank is made of a sufficiently dense foam to dispense with a cardboard blank on which foam plates are arranged.

La géométrie hexagonale permet de répartir les charges plus uniformément autour de l'objet à détruire et il est concevable dans le cadre de l'invention d'accroître encore le nombre de pans.The hexagonal geometry makes it possible to distribute the charges more evenly around the object to be destroyed and it is conceivable in the context of the invention to further increase the number of panels.

Outre la destruction d'armes à contenu explosif, l'invention peut être utilisée pour la préparation à la destruction par détonation de tout objet dangereux, dont le démantèlement par d'autres moyens s'avérerait risqué où trop couteux. En effet l'invention est capable d'être facilement adaptée à des objets de formes et de dimensions diverses et variées dans le cadre de la destruction par détonation de produits dangereux qui est adaptée à la destruction d'un grand nombre de molécules toxiques.In addition to the destruction of weapons with explosive content, the invention can be used for the preparation for the destruction by detonation of any dangerous object, whose dismantling by other means would be risky or too expensive. Indeed the invention is capable of being easily adapted to objects of various shapes and sizes and varied in the context of the destruction by detonation of dangerous products that is suitable for the destruction of a large number of toxic molecules.
