Abstract

The method involves projecting vegetative materials e.g. cuttings and seeds, in association with different products/adjuvants to protect the materials. The materials are associated to a fibrillar membrane for constituting a permeable flexible membrane to protect the cuttings and to stimulate rooting of the cuttings. The materials and the membrane are mixed by starter type phosphate enriched mineral fertilizer and organo-mineral fertilizer. The mixture is applied on a substrate with synthetic plant fiber or natural plant fiber e.g. wood fiber, and plant compost. The membrane contains binding agents e.g. alginic acid, and totally neutral growth activators e.g. humic acid extrat. The substrate is separated from a draining layer by a geotextile with polypropylene fibers, that permit passage of water.

Description

1 La présente invention concerne un procédé d'installation d'une strateThe present invention relates to a method for installing a stratum

végétale sur une toiture terrasse ou à faible pente, ou autres surfaces étanchéifiées ou minérales, en utilisant une technique de projection de boutures et/ou de graines grâce à une machine spécifique composée d'une cuve, d'un agitateur mécanique ou hydraulique, d'une pompe à lobes, à cavités progressives ou centrifuge comportant des ailettes de dimension 7.5 cm X 3.75 cm minimum à 12.7 cm à 6.4 cm entraînée par un moteur thermique, hydraulique, électrique ou par le biais d'une prise de force. Actuellement, la végétalisation des toitures est réalisée par installation sur celle-ci de dalles pré cultivées, de nattes pré ensemencées ou de plantes, posées, plantées ou fixées sur la toiture par un système d'agrafes. Le coût de l'une ou l'autre de ces techniques est un frein sérieux à leurs mises en oeuvre car elles exigent dans un premier temps, la fabrication (natte) et la culture (dalle et plantes), puis dans un second temps l'installation sur la toiture. En fonction du procédé choisi, le coût oscille dans une fourchette estimée entre 50 et 100 { / m2 selon que certaines finitions de la couche d'étanchéité sont prises en compte ou non, et les espèces végétales installées. Pour un système de type extensif (sans arrosage automatique) avec des végétaux couvre-sol comme les Sedums, comparable au procédé décrit ci-après, le coût de la fourniture, hors installation, est estimé entre 40 à 60 {/m2. Pour un résultat équivalent dans un délai de 4 à 8 mois, la fourniture et la mise en oeuvre de la végétalisation par projection de boutures ou semences est 1 à 2 fois inférieure. Le procédé faisant l'objet du brevet permet de s'affranchir de la phase de fabrication ou de culture, et d'augmenter la surface traitée à partir d'une même quantité de matériel végétal. Sa mise en oeuvre est rapide et peu coûteuse en main d'oeuvre car il s'agit d'une application entièrement mécanisée, sans pose ou plantation, ni fixation. La première étape dans la mise en oeuvre de l'invention consiste à installer une couche drainante sur la couche d'étanchéité de la toiture à moins que celle-ci n'existe déjà sous diverses formes ; la plus courante correspondant à une simple épaisseur de quelques centimètres de graviers. En l'absence d'une telle couche, une épaisseur de 5 à 10 cm de graviers d'une granulométrie 5 / 10 mm sera mise en place sur la zone à végétaliser.  plant on a flat roof or low slope, or other sealed or mineral surfaces, using a technique of projection of cuttings and / or seeds through a specific machine composed of a tank, a mechanical or hydraulic stirrer, d a lobe pump with progressive or centrifugal cavities comprising fins 7.5 cm × 3.75 cm minimum at 12.7 cm to 6.4 cm driven by a heat engine, hydraulic motor, electric motor or by means of a power take-off. Currently, the greening of roofs is achieved by installing on this one pre-cultivated slabs, pre-seeded mats or plants, placed, planted or fixed on the roof by a system of staples. The cost of one or the other of these techniques is a serious obstacle to their implementation because they require in the first place, the manufacture (mat) and the culture (slab and plants), then in a second time the installation on the roof. Depending on the chosen method, the cost oscillates in a range estimated between 50 and 100 {/ m2 depending on whether certain finishes of the sealing layer are taken into account or not, and the plant species installed. For an extensive type system (without automatic irrigation) with ground cover plants such as Sedums, comparable to the process described below, the cost of the supply, excluding installation, is estimated between 40 to 60 {/ m2. For an equivalent result in a period of 4 to 8 months, the supply and the implementation of the greening by projection of cuttings or seeds is 1 to 2 times inferior. The process that is the subject of the patent makes it possible to dispense with the manufacturing or cultivation phase and to increase the treated surface from the same quantity of plant material. Its implementation is fast and inexpensive in manpower because it is a fully mechanized application, without installation or planting or fixing. The first step in the implementation of the invention is to install a draining layer on the sealing layer of the roof unless it already exists in various forms; the most common is a simple thickness of a few centimeters of gravel. In the absence of such a layer, a thickness of 5 to 10 cm of gravel 5/10 mm in size will be placed on the area to be planted.

2 2906676 La suite des opérations constitue le procédé au sens strict, faisant l'objet du brevet. Afin d'éviter tout risque de colmatage des drains ou de la couche drainante par infiltration des particules fines et des racines des végétaux, le gravier est couvert par un géotextile dont la structure unique de fibres polypropylènes thermoliées permet le passage de l'eau (porosité : 79 % - Résistance à la traction : 3,5 KN/m2 pour une largeur test de 50 cm). De la qualité de ce film dépend pour une grande part la durée de vie du système. Le substrat installé sur une épaisseur de 5 à 15 cm selon les caractéristiques abiotiques du système, est composé en grande proportion de fibres végétales naturelles (tourbe blonde, fibres de bois, fibres de coco) ou synthétiques et de compost végétal. En fonction de la zone climatique où sera mis en oeuvre le procédé, un copolymère réticulé d'acrylamide et d'acrylamide de potassium ayant les propriétés d'un hydro-rétenteur est incorporé au substrat dans les proportions préconisées par le fabricant et en tenant compte de la charge admissible par la toiture. Le substrat, qui est par ailleurs traité avec un anti germinatif si le mélange appliqué ne contient pas de graines, devra répondre aux normes en vigueur notamment en ce qui concerne la présence de semences d'adventices. Préalablement à l'application du mélange décrit ci après, un léger roulage du • substrat sera réalisé afin d'obtenir une surface parfaitement plane sans pour 55 autant le compacter. Le mélange appliqué à l'aide du matériel décrit préalablement est préparé juste avant la projection. Lorsque le chantier nécessite la réalisation de plusieurs cuves de mélange, un rinçage permettant l'élimination de toute traces de celui-ci dans les différents éléments de la machine utilisée (fond de cuve, pompe, tuyau, etc.) 60 est réalisé. Le mélange appliqué contient les éléments suivants : . La membrane est à base de fibres de bois (densité de 235 Kg/m3 et rétention en eau de 10 Lt/Kg) associées à des agents liants naturelles (acide alginique ; extrait de guar ou bentonite) et synthétiques, ainsi que des activateurs de 65 germination et croissance (extrait d'acides humiques et fuiviques). Après projection et ressuyage, ce qui à l'origine constituait une pâte se structure en membrane fibiillaire constituant une couverture perméable et continue, épousant parfaitement lé micro relief du substrat. L'épaisseur et la qualité de la membrane 2906676 3 doivent permettre d'éviter la formation d'une interface gazeuse entre le substrat 70 et celle-ci afin d'éliminer tout risque de dessèchement qui nuirait à l'enracinement des boutures ou la germination des semences. L'utilisation de cette membrane fibrillaire perméable autorise un arrosage et la ré-humectation du substrat si nécessaire. . Le matériel végétal est constitué de boutures ou de semences, ou même d'un 75 mélange des deux, dans des proportions calculées pour obtenir une couverture rapide sans risque de mise en compétition lorsque des boutures sont associées à des graines. Les boutures doivent avoir une taille cohérente avec l'objectif de s'enraciner rapidement sans pour autant dépasser 4 à 5 cm afin d'éviter le colmatage de la pompe de la machine ou leur propre broyage. On utilisera par 80 exemple des boutures de 0,5 à 1,5 cm pour du Sedum sp., alors qu'avec une espèce comme le Frankenia laevis, la taille des boutures sera comprise entre 1,5 et 3 cm. . Deux types d'engrais achèvent la constitution du mélange projeté. Une base organique ou organo-minérale (N/P/K = 6/5/5), contenant au minimum 50 % de 85 matières organiques avec incorporation d'algues et tourteaux, est complétée par un engrais minéral de type starter (N/P/K = 10/52/10) à forte proportion de phosphates qui accélèrent les processus d'enracinement des boutures. Dans le cas d'une projection à base de graines ou d'un mélange graines / boutures, l'engrais minéral décrit précédemment n'est pas utilisé.The subsequent operations constitute the process in the strict sense, which is the subject of the patent. In order to avoid any risk of clogging the drains or the draining layer by infiltration of fine particles and plant roots, the gravel is covered by a geotextile whose unique structure of thermolated polypropylene fibers allows the passage of water (porosity : 79% - Tensile strength: 3.5 KN / m2 for a test width of 50 cm). The quality of this film depends to a large extent on the life of the system. The substrate, which is 5 to 15 cm thick depending on the abiotic characteristics of the system, is composed in large part of natural vegetable fibers (blonde peat, wood fibers, coconut fibers) or synthetic fibers and vegetable compost. Depending on the climatic zone where the process will be carried out, a crosslinked copolymer of acrylamide and of potassium acrylamide having the properties of a hydro-retentor is incorporated into the substrate in the proportions recommended by the manufacturer and taking into account the permissible load by the roof. The substrate, which is also treated with an anti-germinative if the mixture applied does not contain seeds, must meet the standards in force, particularly with regard to the presence of weed seeds. Prior to the application of the mixture described hereinafter, a slight rolling of the substrate will be carried out in order to obtain a perfectly flat surface without so much as compacting it. The mixture applied using the material described previously is prepared just before the projection. When the site requires the production of several mixing tanks, a rinse allowing the removal of any traces of it in the various elements of the machine used (bottom of tank, pump, pipe, etc.) 60 is made. The applied mixture contains the following elements: The membrane is based on wood fibers (density 235 Kg / m3 and water retention of 10 Lt / kg) combined with natural binding agents (alginic acid, guar or bentonite extract) and synthetic binders, as well as Germination and growth (extract of humic and fuivic acids). After spraying and drying, which originally constituted a paste is structured fibiillary membrane constituting a permeable and continuous cover, perfectly marrying the micro-relief of the substrate. The thickness and the quality of the membrane 2906676 3 must make it possible to avoid the formation of a gaseous interface between the substrate 70 and this one in order to eliminate any risk of drying which would be detrimental to the rooting of the cuttings or the germination seeds. The use of this permeable fibrous membrane allows watering and re-wetting of the substrate if necessary. . The plant material consists of cuttings or seeds, or even a mixture of the two, in proportions calculated to obtain rapid coverage without risk of competition when cuttings are associated with seeds. The cuttings must have a size consistent with the objective of rooting quickly without exceeding 4 to 5 cm in order to avoid clogging of the pump of the machine or their own grinding. For example, cuttings of 0.5 to 1.5 cm for Sedum sp. Will be used, whereas with a species such as Frankenia laevis, the size of the cuttings will be between 1.5 and 3 cm. . Two types of fertilizer complete the constitution of the projected mixture. An organic or organo-mineral base (N / P / K = 6/5/5), containing at least 50% of 85 organic matter with incorporation of algae and cake, is supplemented by a mineral starter fertilizer (N / P / K = 10/52/10) with a high proportion of phosphates which accelerate the rooting process of the cuttings. In the case of a seed-based projection or seed / cuttings mixture, the mineral fertilizer described above is not used.

90 L'application du mélange peut être réalisé manuellement mais l'usage d'un matériel spécifique est préférable car elle garantie une application homogène. L'épaisseur du mélange projeté est de l'ordre de 0.2 à 0.5 cm, mais dépend des conditions climatiques et de la saison pendant laquelle le travail est réalisé. La mise en oeuvre du procédé décrit est impérativement précédé d'une visite des 95 lieux afin d'établir la liste précise et le dosage des différents intrants dont les espèces ou variétés végétales à utiliser. Ce type de végétalisation, dite extensive, ne nécessite aucun entretien particulier si ce n'est une visite annuelle afin d'éliminer toutes plantules de type ligneuse (arbuste ou arbre) qui auraient pu se développer malencontreusement car le 100 système racinaire, généralement pivotant et puissant, pourrait endommager le film anti-racines, puis à terme la couche d'étanchéité de la toiture.The application of the mixture can be done manually but the use of a specific material is preferable because it guarantees a homogeneous application. The thickness of the projected mixture is of the order of 0.2 to 0.5 cm, but depends on the climatic conditions and the season during which the work is carried out. The implementation of the described method is imperatively preceded by a visit of the 95 places in order to establish the precise list and the dosage of the different inputs of which the species or plant varieties to use. This type of vegetation, called extensive, requires no special maintenance except an annual visit to eliminate all seedlings of the woody type (shrub or tree) that could have developed inadvertently because the 100 root system, generally rotating and powerful, could damage the anti-root film, and eventually the waterproofing layer of the roof.

2906676 4 Cette visite annuelle permet aussi un apport d'engrais préférentiellement organique de manière à ce que la libération des éléments fertilisants soit étalé dans le temps et que les précipitations ne puissent lessiver cet apport.2906676 4 This annual visit also allows for a preferentially organic fertilizer intake so that the release of nutrients is spread over time and that precipitation can not wash off this input.

105 En région chaude où l'évaporation importante peut accélérer le dessèchement et par conséquent nuire à l'enracinement des boutures ou graines, l'incorporation de I' hydro-retenteur dans le substrat, peut être complété par la mise en place temporaire d'un système d'irrigation de type arroseur ou bras oscillant pendant une durée de l'ordre de 1 à 2 mois. Ce système peut être piloté manuellement ou 110 automatiquement. .5In hot areas where significant evaporation can accelerate desiccation and consequently harm the rooting of cuttings or seeds, the incorporation of the hydro-retentor into the substrate may be supplemented by the temporary establishment of a sprinkler or swingarm type irrigation system for a duration of the order of 1 to 2 months. This system can be controlled manually or automatically. .5
