Abstract
Description
La présente invention concerne un procédé de lutte contre l'incendie, par exemple contre les incendies de forêts.The present invention relates to a fire-fighting method, for example against forest fires.
Actuellement, les moyens de lutte contre les incendies tels que, par exemple, ceux de forêts, sont basés sur deux grands principes. Le premier est préventif et consiste à établir dans la forêt des zones dans lesquelles le combustible favorisant la progression d'un feu (élément propagatif) est partiellement ou complètement enlevé (zone coupe-feu). Ainsi un tel procédé est enseigné par FR-A-1 209 202 dans lequel des saignées entières sont effectuées dans la forêt et les arbres sont en outre remplacés par de la canne pour constituer une végétation qui atténue les déplacements d'air et arrête dans leur course les projectiles enflammés. Un tel procédé repose sur le principe des coupes-feux et nécessite par conséquent la destruction de zones importantes de forêt.Currently, the means of fighting fires such as, for example, those of forests, are based on two main principles. The first is preventive and consists in establishing in the forest areas in which the fuel favoring the progression of a fire (propagating element) is partially or completely removed (fire stop area). Thus, such a method is taught by FR-A-1 209 202 in which whole bloodletting is carried out in the forest and the trees are also replaced by cane to constitute a vegetation which attenuates the movement of air and stops in their race the flaming projectiles. Such a process is based on the principle of firebreaks and therefore requires the destruction of large areas of forest.
Le deuxième principe consiste à lutter en intervenant activement sur le front du feu afin de rendre la végétation en aval de celui-ci non combustible (élément non propagatif), par apport d'eau additionnée ou non de produits retardants. Cet apport se faisant par avions ou motopompes de façon que la zone mouillée soit la plus continue possible, voire même submergée par l'eau.The second principle consists in fighting by intervening actively on the front of the fire in order to make the vegetation downstream of it not combustible (non-propagating element), by adding water with or without delaying products. This contribution is made by airplanes or motor pumps so that the wet area is as continuous as possible, or even submerged by water.
Ainsi les brevets FR-A-2 352 870 et FR-A-2 344 302 et US-A-4 616 711 enseignent différents moyens de rendre des zones non-propagatives de façon à constituer des bandes de coupe-feu.Thus the patents FR-A-2 352 870 and FR-A-2 344 302 and US-A-4 616 711 teach different means of rendering zones non-propagative so as to constitute bands of firebreaks.
Ces moyens de prévention et de lutte présentent cependant des inconvénients. Ainsi, la création de zones coupe-feu impose la suppression complète de la végétation sur des surfaces pouvant être importantes, d'où un coût élevé et un préjudice à la nature. De même, dans le cas où on effectue des débroussaillages, ceux-ci, pour être efficaces doivent être très souvent renouvelés, ce qui occasionne des coûts importants. Enfin l'intervention active, pour être efficace nécessite des conditions de rapidité et de précision de l'action, de continuité et de quantité de moyens. Ces conditions présentent souvent des dangers pour les intervenants, par exemple vol à basse altitude des aéronefs, distance réduite par rapport au feu d'un grand nombre de personnes.These means of prevention and control have drawbacks, however. So the creation of zones firebreak requires complete removal of vegetation on potentially large areas, resulting in high cost and harm to nature. Similarly, in the case where brushcutting is carried out, in order to be effective, it must very often be renewed, which causes significant costs. Finally, active intervention, to be effective, requires conditions of speed and precision of action, continuity and quantity of means. These conditions often present dangers for responders, for example low-flying aircraft, reduced distance from the fire of a large number of people.
Un autre inconvénient de l'art antérieur était principalement de maximiser les moyens préventifs ou de lutte de façon à être sûr d'arrêter le feu.Another drawback of the prior art was mainly to maximize the preventive or control means so as to be sure of stopping the fire.
Un premier but de l'invention est de proposer un procédé de lutte contre l'incendie permettant d'optimiser les moyens de lutte contre l'incendie par application de la théorie de la percolation.A first object of the invention is to propose a method of fighting against fire making it possible to optimize the means of fighting against fire by applying the theory of percolation.
Ce premier but est atteint par le fait que le procédé de lutte contre l'incendie consistant, dans une zone donnée, à partager cette zone en sites propagatifs dans lesquels des éléments constituent un combustible encourageant la progression du feu et en sites non propagatifs dans lesquels des éléments sont incombustibles ou rendus incombustibles par des moyens, caractérisé en ce qu'il consiste à réaliser une distribution aléatoire à l'intérieur de la zone donnée de sites propagatifs et non propagatifs de façon à ce que le nombre de sites propagatifs et non propagatifs soit supérieur à 150 et à ce que le pourcentage de sites non propagatifs que le feu est susceptible de rencontrer soit supérieur à un seuil donné inférieur à 100% du nombre total de sites.This first object is achieved by the fact that the fire-fighting method consisting, in a given area, in dividing this area into propagative sites in which elements constitute a fuel encouraging the progression of fire and into non-propagative sites in which elements are non-combustible or made non-combustible by means, characterized in that it consists in carrying out a random distribution within the given area of propagative and non-propagative sites so that the number of propagative and non-propagative sites is greater than 150 and that the percentage of non-propagative sites that the fire is likely to encounter is greater than a given threshold less than 100% of the total number of sites.
Selon une autre caractéristique le nombre de sites non propagatifs varie dans une plage comprise entre 25 et 60% de l'ensemble des sites.According to another characteristic, the number of non-propagative sites varies in a range between 25 and 60% of all the sites.
Selon une autre caractéristique, le seuil varie dans une plage comprise entre 25 et 60 % pour les feux de forêts.According to another characteristic, the threshold varies in a range between 25 and 60% for forest fires.
Selon une autre caractéristique, le seuil est choisi de préférence égal à 42 % pour arrêter un feu de forêt en l'absence de vent.According to another characteristic, the threshold is preferably chosen to be 42% to stop a forest fire in the absence of wind.
Un autre but de l'invention est de proposer un procédé de lutte préventif contre l'incendie permettant d'optimiser et réduire les coûts de débrouissaillange et de création de zones coupe-feu.Another object of the invention is to propose a preventive fire fighting method making it possible to optimize and reduce the costs of clearing and creating firebreak zones.
Ce but est atteint par le fait que le procédé selon l'invention est caractérisé en ce que les éléments non propagatifs sont constitués par des végétaux non combustibles plantés dans les proportions indiquées et suivant une répartition aléatoire.This object is achieved by the fact that the method according to the invention is characterized in that the non-propagative elements consist of non-combustible plants planted in the proportions indicated and according to a random distribution.
Ce but est atteint par le fait que les moyens du procédé pour rendre non propagatifs les éléments d'une zone sont constitués par des têtes d'arrosage à jets de fluide humidifiants, disposées de façon que la surface arrosée soit supérieur au seuil donné.This object is achieved by the fact that the means of the method for rendering the elements of a zone non-propagative are constituted by sprinkling heads with humidifying fluid jets, arranged so that the area sprayed is greater than the given threshold.
Selon une autre caractéristique, les moyens du procédé pour rendre non propagatifs les éléments d'une zone sont constitués par des bombes ou containers transportables, projetés ou lâchés.According to another characteristic, the means of the method for making the elements of an area non-propagative consist of transportable bombs or containers, projected or dropped.
Selon une autre caractéristique, on utilise comme fluide humidifiant de l'eau ou une mousse, selon une autre caractéristique, le fluide humidifiant peut contenir des retardants.According to another characteristic, water or foam is used as the humidifying fluid, according to another characteristic, the humidifying fluid may contain retardants.
Selon une autre caractéristique du procédé, les éléments rendus non propagatifs sont des éléments de constructions immobilières.According to another characteristic of the process, the elements rendered non-propagative are elements of building construction.
D'autres caractéristiques et avantages de la présente invention apparaîtront plus clairement à la lecture de la description ci-après, faite en référence à la figure unique représentant l'utilisation du procédé de l'invention dans la lutte contre l'incendie.Other characteristics and advantages of the present invention will appear more clearly on reading the description below, made with reference to the single figure representing the use of the method of the invention in the fight against fire.
La figure 1 représente l'utilisation de la théorie de la percolation dans un procédé de lutte contre l'incendie.Figure 1 shows the use of percolation theory in a fire fighting process.
Selon cette théorie, un phénomène propagatif tel que le feu ne peut se développer dans un milieu où la proportion des sites inactifs ou non propagatifs par rapport aux sites actifs ou propagatifs est supérieure ou égale à un nombre qu'il est convenu d'appeler seuil de percolation. Ainsi si l'on prend l'exemple de la figure 1, dans laquelle un site combustible tel qu'une forêt est divisé en trois zones, une première zone comportant exclusivement des sites combustibles (11), une deuxième zone (2) de largeur (L) comportant une distribution aléatoire de sites combustibles (21) et de sites non combustibles (20) (sites représentés par des hâchures), et dont la proportion est supérieure au seuil de percolation.According to this theory, a propagative phenomenon such as fire cannot develop in an environment where the proportion of inactive or non-propagative sites compared to active or propagative sites is greater than or equal to a number which it is agreed to call threshold percolation. So if we take the example of figure 1, in which a combustible site such as a forest is divided into three zones, a first zone comprising exclusively combustible sites (11), a second zone (2) of width (L) comprising a random distribution of combustible sites (21) and non-combustible sites (20) (sites represented by hatching), and the proportion of which is greater than the percolation threshold.
Une troisième zone (3) est constituée comme la première par des sites exclusivement combustibles (31). On a constaté qu'un feu se propageant dans le sens des flèches (A) se propage dans la zone (1) et se trouve arrêté au niveau de la zone (2) lorsque la proportion de sites non propagatifs (20) par rapport aux sites propagatifs (21) dépasse un certain pourcentage. Dans ce cas, le feu ne se propage pas à l'intérieur de la zone (3) et l'incendie s'arrête dans la zone (2).A third zone (3) is constituted as the first by exclusively combustible sites (31). It has been observed that a fire propagating in the direction of the arrows (A) propagates in the zone (1) and is stopped at the level of the zone (2) when the proportion of non-propagative sites (20) relative to the propagative sites (21) exceeds a certain percentage. In this case, the fire does not spread inside the zone (3) and the fire stops in the zone (2).
Par l'expérience, on a constaté que dans le cas d'un seuil compris entre 25 et 60 % pour les feux de forêts on arrivait soit à ralentir, soit à arrêter l'incendie, en fonction des conditions de vent et du seuil choisi. De préférence, lorsque l'on veut arrêter un incendie de forêt, en l'absence de vent, on choisira un seuil égal à 42 %. De façon avantageuse, pour avoir un effet de percolation, il faut, pour une zone donnée un nombre de sites propagatifs et non propagatifs supérieur à 150 et le nombre de sites propagatifs doit représenter une fourchette de 25 à 60% de l'ensemble des sites, ce qui peut représenter une surface ou un volume équivalent de l'ordre de 25 à 60% de la surface ou du volume total de la zone considérée.Experience has shown that in the case of a threshold between 25 and 60% for forest fires, we can either slow down or stop the fire, depending on the wind conditions and the chosen threshold. . Preferably, when we want to stop a forest fire, in the absence of wind, we will choose a threshold equal to 42%. Advantageously, to have a percolation effect, it is necessary, for a given area, a number of propagative and non-propagative sites greater than 150 and the number of propagative sites must represent a range of 25 to 60% of all the sites , which may represent an area or equivalent volume of the order of 25 to 60% of the area or total volume of the area considered.
Les sites non propagatifs seront constitués de préférence soit par des végétaux non combustibles plantés isolément ou en bosquets parmi la végétation naturelle existante. Ces végétaux seront choisis parmi les essences non combustibles que l'on connait ou qui pourront être développées ultérieurement.Non-propagative sites will preferably consist of either non-combustible plants planted singly or in thickets among existing natural vegetation. These plants will be chosen from non-combustible species that are known or that can be developed later.
Un autre moyen de rendre les éléments d'un site non propagatifs peut consister à implanter des buses ou bouches fixes produisant des jets de fluide tel que de l'eau ou de la mousse et pouvant contenir des retardants. Ces éléments hydrants ou buses sont mis en fonctionnement sur commande manuelle ou automatique à l'approche du feu et leur répartition est telle que les zones arrosées par ces éléments et rendues non propagatives correspondent au seuil de ralentissement ou au seuil d'arrêt de l'incendie indiqué ci-dessus. De façon connue une commande automatique provenant d'un dispositif de détection du feu pourra commander ces buses.Another means of rendering the elements of a site non-propagative can consist of implanting nozzles or fixed mouths producing jets of fluid such as water or foam and which may contain retardants. These hydrating elements or nozzles are put into operation on manual or automatic control when approaching the fire and their distribution is such that the zones watered by these elements and made non-propagative correspond to the deceleration threshold or the threshold for stopping the fire indicated above. In known manner, an automatic control coming from a fire detection device can control these nozzles.
On comprend aisément que le procédé de l'invention peut être utilisé également pour la lutte contre les incendies dans les immeubles de façon à optimiser le nombre de buses et d'éléments de détection, ceci d'une part pour réduire les coûts de l'installation et d'autre part pour limiter les dégats dûs à l'inondation des locaux. De même, le principe précédent permettant de combiner les zones combustibles et les zones non combustibles peut être utilisé de façon avantageuse dans la construction des maisons pour limiter la quantité de matériaux non combustibles. Ceci pour diminuer les coûts de la construction, sans diminuer la sécurité et la prévention.It is easily understood that the method of the invention can also be used for fighting fires in buildings so as to optimize the number of nozzles and detection elements, this on the one hand to reduce the costs of installation and on the other hand to limit the damage due to the flooding of the premises. Likewise, the above principle allowing the combination of combustible zones and non-combustible zones can be advantageously used in the construction of houses to limit the quantity of non-combustible materials. This is to reduce construction costs, without reducing safety and prevention.
Un autre moyen permettant de rendre les sites non propagatifs peut être constitué par des bombes projetées ou lachées à l'aval du front du feu et dispersant lors de l'explosion un fluide tel que de l'eau ou de la mousse contenant ou non des retardants. Ces moyens de projection du fluide d'humidification de la végétation du site projetant le fluide du bas vers le haut, présentent l'avantage de tenir compte du caractère fractal de la végétation, c'est-à-dire de la forme en arborescence des végétaux. Dans ce cas la projection faite dans le sens de l'arborescence assure une bien meilleure humidification que celle assurée, par exemple, par la projection ou le lâchage d'eau à partir d'un aéronef.Another means of rendering the sites non-propagative can consist of bombs thrown or dropped downstream of the fire front and dispersing during the explosion a fluid such as water or foam containing or not retardants. These means for projecting the humidification fluid from the vegetation of the site projecting the fluid from the bottom up, have the advantage of taking into account the fractal nature of the vegetation, that is to say the tree-like shape of the plants. In this case the projection made in the direction of the tree ensures a much better humidification than that ensured, for example, by the projection or the release of water from an aircraft.
Ainsi, le procédé utilisé et les différents moyens permettant la mise en oeuvre du procédé en réalisant des zones d'éléments non propagatifs contribuent à l'optimisation de la lutte contre le feu.Thus, the method used and the various means allowing the implementation of the method by producing zones of non-propagative elements contribute to the optimization of the fight against fire.
Comme on l'a vu précédemment, le procédé de lutte contre l'incendie consiste à utiliser des éléments non propagatifs ou à mettre en oeuvre des moyens pour rendre non propagatifs les éléments combustibles, de façon que le pourcentage des sites non propagatifs que l'incendie est susceptible de rencontrer soit supérieur à un seuil donné inférieur à 100 % .As we have seen above, the fire-fighting method consists in using non-propagating elements or in implementing means to render the combustible elements non-propagative, so that the percentage of non-propagating sites that the fire is likely to meet either above a given threshold below 100%.
L'avantage d'un tel procédé utilisant la théorie de la percolation est de pouvoir à la fois être utilisé comme moyen de lutte contre le feu mais également en tant qu'élément préventif.The advantage of such a method using the percolation theory is that it can be used both as a means of fighting fire but also as a preventive element.
D'autres modifications à la portée de l'homme de métier sont possibles dans le cadre de l'invention tel que défini par les revendications. Ainsi dans le cas de l'utilisation des bombes à eau, la neutralisation d'un site peut se faire par explosion au sein de la végétation d'une enveloppe contenant une quantité spécifiée d'eau. Cette explosion est provoquée, soit par l'impact au sol, soit par télécommande à une hauteur déterminée par rapport au sol. Dans le cas de l'explosion par impact au sol, on utilise de préférence des bombes à enveloppe souple, tandis que des enveloppes rigides servent dans le cas d'explosion télécommandée.Other modifications within the scope of those skilled in the art are possible within the scope of the invention as defined by the claims. Thus in the case of the use of water bombs, the neutralization of a site can be done by explosion within the vegetation of an envelope containing a specified quantity of water. This explosion is caused either by impact with the ground, or by remote control at a determined height above the ground. In the case of a ground impact explosion, bombs with a flexible envelope are preferably used, while rigid envelopes are used in the case of a remote-controlled explosion.
