Abstract

The invention concerns a method which consists in: driving into the ground (or into a wall) a hollow socket (4), filled (before or after the driving process) with a temporarily fluid material. The socket is perforated with a plurality of orifices: round holes, slots (or both); expelling the material by some pressure means, through the orifices which transforms it into roots or strata, before it sets, or is solidified, or is polymerised, depending on the type of material selected for use. In some cases, the socket itself, when it bursts, is transformed into roots .

Description

SCELLEMENTS PAR RACINES SYNTHETIQUES OU METALLIQUES SEALS BY SYNTHETIC OR METAL ROOTS
Les meilleurs encrages sont fournis par "Dame Nature" les RACINES.The best inking is provided by "Mother Nature" ROOTS.
Des plus petites plantes, aux arbres géants, il n'est de meilleurs scellements. L'idéal, donc, pour fixer un objet au sol, ou dans une paroi est de lui offrir des "racines", que ce soit pour un poteau, un piquet, un plancher, ou tout autre chose.From the smallest plants, to the giant trees, there is no better seal. The ideal, therefore, to fix an object to the ground, or in a wall is to offer it "roots", whether for a pole, a stake, a floor, or anything else.
L'Invention consiste en un procédé capable de produire ces "racines".The invention consists of a process capable of producing these "roots".
Pratique et Niable, ce procédé d'enracinement est simple, efficace, économique et pratiquement instantané (ou, au moins, extrêmement rapide). Il consiste à enfoncer, préalablement une douille creuse 4 (FIG. 1), remplie (avant ou après suivant le moyen de fbnçage), avec une matière 7 (FIG. 2), provisoirement fluide.Practical and Niable, this rooting process is simple, effective, economical and practically instantaneous (or, at least, extremely fast). It consists in driving in, beforehand, a hollow socket 4 (FIG. 1), filled (before or after depending on the finishing means), with a material 7 (FIG. 2), temporarily fluid.
La douille 4 est percée de multiples orifices : trous ronds 3, fentes 2, ou les deux, (FIG. 2). On expulse la matière par un quelconque moyen de pression 8 au travers des orifices qui la transforment en "racines" 6 ou en "strates" 5, avant qu'elle ne se fige, ou se solidifie, ou se polymérise, suivant le choix de ladite matière utilisée (FIG. 2).The socket 4 is pierced with multiple orifices: round holes 3, slots 2, or both, (FIG. 2). The material is expelled by any pressure means 8 through orifices which transform it into "roots" 6 or into "strata" 5, before it freezes, or solidifies, or polymerizes, depending on the choice of said material used (FIG. 2).
Les fentes 2 (FIG. 2), étant de préférence perpendiculaires à l'axe longitudinal de la douille, afin que les "strates" 5 offrent à cette dernière la meilleur résistance à P arrachement.The slots 2 (FIG. 2), preferably being perpendicular to the longitudinal axis of the sleeve, so that the "strata" 5 offer the latter the best resistance to pulling out.
La section de la douille 4 carrée, ronde, triangulaire, ou tout autre forme, importe peu :• l'essentiel est que l'on puisse y introduire un élément qui exercera, en se déplaçant du haut en bas de ladite douille 4, une pression interne comme un piston ou une seringue.The section of the socket 4 square, round, triangular, or any other shape, does not matter: • the main thing is that one can introduce an element which will exert, by moving from top to bottom of said socket 4, a internal pressure like a plunger or syringe.
L'élément piston Pi peut être, dans certains cas, fixé à la base d'un poteau ou piquetThe piston element Pi can be, in certain cases, fixed to the base of a post or stake
Pt, ou encore faire partie intégrante (FIG. 3), de la chose à sceller (FIG. 3). Il faut choisir pour élément/piston Pi, une qualité de matériau qui "colle" à la matière des futures racines, si cet élément est destiné à rester dans la douille, ou, au contraire, qu'il ne colle pas du tout, afin de réutiliser à nouveau ledit élément.Pt, or even be an integral part (FIG. 3), of the thing to be sealed (FIG. 3). It is necessary to choose for element / piston Pi, a quality of material which "sticks" to the material of future roots, if this element is intended to remain in the socket, or, on the contrary, that it does not stick at all, so to reuse said element again.
Le choix des matériaux pour l'élément piston Pi est donc fonction de :The choice of materials for the piston element Pi therefore depends on:
1°- l'objet à sceller,1 ° - the object to be sealed,
2°- de l'abandon de Pélément/piston Pi dans la douille, 3°- de la ré-utilisation de Pélément/piston Pi qui pourrait n'être qu'un MARTYRE,2 ° - the abandonment of the Element / piston Pi in the socket, 3 ° - the re-use of the Element / piston Pi which could be only a MARTYRE,
(pièce sur laquelle on exerce des percussions),(piece on which we exercise percussion),
4°- de la matière des futures racines 6.4 ° - matter of future roots 6.
Cette douille 4 peut être dotée à sa partie supérieure d'une collerette 1 (FIG. 2), qui fera appui ou limiteur de profondeur et système anti-torsion lorsque ladite douille 4 sera complètement enfoncée.This sleeve 4 can be provided at its upper part with a collar 1 (FIG. 2), which will act as a support or depth limiter and anti-twist system when said sleeve 4 is fully inserted.
La douille 4 est immobilisée, après son enfoncement, par des griffes 18 et 18' (FIG. 6) qui la maintiennent par sa collerette 1 (FIG. 6), ou par une plaque en deux pièces 13 (FIG, 4), qui prend ladite douille 4 entre ces dernières. Plaques, qui peuvent par un embouti central, maintenir la douille quelques centimètres au dessous du niveau du sol, ou de la surface ou est enfoncée ladite douille 4. On maintient la douille 4 dans sa position pour qu'elle ne soit pas déplacée ou enfoncée au-delà de la profondeur souhaitée. Position qui, sans son immobilisation, pourrait être modifiée par la pression qui va être exercée à l'intérieur de la douille 4 par le piston Pi. Pression qui expulsera, par les trous 3 et fentes 2 de la douille 4, la matière 7 qui deviendra des "racines" 6 en se répandant dans les interstices des pierres, graviers, fissures, cavités, trous de vers, galeries d'insectes, etc.,The socket 4 is immobilized, after its insertion, by claws 18 and 18 '(FIG. 6) which hold it by its collar 1 (FIG. 6), or by a two-piece plate 13 (FIG, 4), which takes said socket 4 therebetween. Plates, which can by a central stamp, maintain the socket a few centimeters below the level of the ground, or of the surface where said socket 4 is pressed. The socket 4 is kept in its position so that it is not moved or pressed beyond the desired depth. Position which, without its immobilization, could be modified by the pressure which will be exerted inside the sleeve 4 by the piston Pi. Pressure which will expel, through the holes 3 and slots 2 of the sleeve 4, the material 7 which will become "roots" 6 by spreading in the interstices of stones, gravel, cracks, cavities, wormholes, insect galleries, etc.,
FEUILLE RECTIFIÉE (RÈGLE 91) et en particulier dans le sable. Plus la pression exercée sur la matière sera forte, plus les racines 6 s'étendront .Cette pression peut-être obtenue de différentes façons :RECTIFIED SHEET (RULE 91) and especially in the sand. The greater the pressure exerted on the material, the more the roots 6 will extend. This pressure can be obtained in different ways:
— par simple poussée mécanique, directement dans la douille 4, avec un vérin par exemple, — par vissage du piston 15 (FIG. 5), dans la douille 4, auquel cas cette dernière pourrait être dotée d'ailettes 16 (FIG. 5), pour l'empêcher de tourner, si les griffes ne sont pas suffisantes,- by simple mechanical push, directly in the socket 4, with a jack for example, - by screwing the piston 15 (FIG. 5), in the socket 4, in which case the latter could be provided with fins 16 (FIG. 5 ), to prevent it from turning, if the claws are not sufficient,
~ par percussion (FIG. 7A à 7D) mécanique ou manuelle, avec un martyre 8 (FIG. 7A), faisant office de piston. Cette solution, probablement la meilleure, facilitera la propagation de la matière dont la pénétration dans l'environnement de la douille se trouvera proportionnellement accrue par la violence des chocs.~ by percussion (FIG. 7A to 7D) mechanical or manual, with a martyr 8 (FIG. 7A), acting as a piston. This solution, probably the best, will facilitate the propagation of the material whose penetration into the environment of the sleeve will be proportionally increased by the violence of the shocks.
Pour la matière 7 (FIG. 2), qui doit devenir des racines, on évitera les produits qui deviennent cassants, pour ne pas être brisés lorsque lesdites racines seront figées ou polymérisées. Une certaine souplesse, même faible, est donc recommandée. Cette matière peut être :For material 7 (FIG. 2), which must become roots, products which become brittle will be avoided, so as not to be broken when said roots are frozen or polymerized. Some flexibility, however weak, is therefore recommended. This material can be:
— du plastique fondu, pas trop liquide, à température moyenne, comme certains vinyles (environ 100°), qui se figera en terre, en fin de pression. Cette matière sera entretenue fondue, en chantier, soit par bain, soit directement dans les douilles qui seront disposées dans une sorte de bain-marie, ou chauffées électriquement par des résistances, - de la colle, assez épaisse qui se solidifiera à la fin de la pression dans la douille.- molten plastic, not too liquid, at medium temperature, like certain vinyls (around 100 °), which will freeze in the ground at the end of pressure. This material will be kept melted, under construction, either by bath, or directly in the sockets which will be arranged in a sort of water bath, or electrically heated by resistors, - glue, quite thick which will solidify at the end of pressure in the socket.
— de la colle pas trop liquide, en deux parties (plastique et durcisseur, ou catalyseur) qui se solidifieront également en fin de pression. Cette dernière méthode permet de doser 1e minutage de prise avec beaucoup de précision.- glue not too liquid, in two parts (plastic and hardener, or catalyst) which will also solidify at the end of pressure. This latter method makes it possible to dose the setting timing very precisely.
Dans tous les cas, on a un choix très étendu et l'on doit rester maître de la durée de prise de la matière, qui suit de près la poussée du piston dans la douille. Toutes ces solutions sont, en générale peu onéreuses, comme certaines matières utilisées pour les chevilles chimiques murales, ou le goudron du bitume.In all cases, there is a very wide choice and one must remain in control of the duration of setting of the material, which closely follows the thrust of the piston in the socket. All of these solutions are generally inexpensive, like certain materials used for wall chemical anchors, or bitumen tar.
Les racines 6, au sortir des trous 3 de la douille 4, seront, au moins au départ, de forme cylindrique, alors qu'au sortir des fentes 2, elles seront plutôt en strates 5 (FIG, 2), permettant ainsi à ladite douille de mieux résister à l'arrachement.The roots 6, at the exit from the holes 3 of the socket 4, will, at least at the start, be cylindrical, while at the exit from the slots 2, they will rather be in layers 5 (FIG, 2), thus allowing said sleeve to better resist tearing.
La résistance générale de ces scellements devra correspondre, en principe à la masse du volume de l'environnement concerné autour de la douille 4, qui sera prisonnière de l'envahissement des racines 6.The general resistance of these seals should correspond, in principle to the mass of the volume of the environment concerned around the socket 4, which will be trapped by the invasion of the roots 6.
Les fentes 2 ou trous 3, ou encore les deux formes conjointes d'orifices, devront être plus nombreux vers la base de la douille 4, car c'est à la base que les racines 6 doivent être • disposées au mieux pour avoir un maximum d'efficacité.The slots 2 or holes 3, or even the two joint forms of orifices, must be more numerous towards the base of the socket 4, because it is at the base that the roots 6 must be • arranged as best as possible in order to have a maximum efficiency.
On peut prévoir, dans certains cas, des douilles 4 très profondes, avec des racines 6 uniquement à la base. Par exemple, ce procédé de scellement allié à une clôture basse, sera particulièrement efficace pour fixer des dunes de sable, et empêcher, sinon retarder le déplacement de ces dernières par le vent ou l'érosion.In some cases, very deep sockets 4 can be provided, with roots 6 only at the base. For example, this sealing process, combined with a low fence, will be particularly effective in fixing sand dunes, and preventing, if not delaying, their displacement by wind or erosion.
PROCESSUS D'UTILISATION DU PROCEDE, A TITRE D'EXEMPLE, POUR LE SCELLEMENT D'UN PIQUET EN SOL DUR (FIG. 7B)PROCESS OF USING THE PROCESS, FOR EXAMPLE, FOR SEALING A STAKE IN HARD GROUND (FIG. 7B)
On utilisera un outil 25 (FIG. 7C), sous forme de broches avec masse coulissante 26 pour les percussions, (ou un marteau-piqueur muni d'une broche) la douille 4 (FIG. 7B), est ouverte à sa base pour le passage de la pointe de la broche 25 (FIG. 7C).We will use a tool 25 (FIG. 7C), in the form of pins with sliding mass 26 for percussion, (or a jackhammer provided with a pin) the socket 4 (FIG. 7B), is open at its base for the passage of the tip of the pin 25 (FIG. 7C).
Cette dernière fera le passage de la douille tout en empêchant que ladite douille 4 soit endommagée, surtout lorsqu'il s'agit d'un sol pierreux ou rocailleux. Si la broche, reste coincée, en fin de fonçage, on se servira d'une longue pince Monseigneur 27 (FIG. 7A),The latter will pass the sleeve while preventing said sleeve 4 from being damaged, especially when it is a stony or rocky ground. If the pin gets stuck in the end bores, one will use a long crowbar 27 (FIG. 7A),
FEUILLE RECTIFIÉE (REGLE 91) qui prendra appui sur la collerette de la broche 1 (FIG. 7A), pour dégager l'outil. Une fois la douille 4 en place, on l'immobilise par sa collerette 1, et l'on introduit un "bouchon" approprié 24 (FIG. 7D), pour obturer le bas de la douille 4, là où passait la pointe de la broche. Ce bouchon 24 comble en même temps l'espace sous la douille 4, qui a été creusé par la pointe de la broche 29 (FIG. 7C). Ce bouchon 24 sera percé d'un ou plusieurs trous 24' (FIG. 7D), pour laisser l'air passer, lors de sa mise en place et éventuellement, pour laisser passer également quelques futures racines. On remplit la douille 4 de la matière 7 des futures racines, (plastique fondu, ou colle, ou matière polymérisable, ou ...) et on expulse cette matière 7 avec l'élément faisant piston Pi, (élément qui peut faire partie du piquet à sceller). La matière 7 s'échappant par les fentes 2 ou trous 3, devient racines et strates. On retire l'élément piston Pi s'il ne fait pas parti du piquet et l'on introduit ce dernier qui peut se coller avec le reliquat de matière qui reste au fond de la douille, ou être enfoncé en force.RECTIFIED SHEET (RULE 91) which will rest on the collar of spindle 1 (FIG. 7A), to release the tool. Once the socket 4 in place, it is immobilized by its collar 1, and a suitable "plug" 24 (FIG. 7D) is introduced, to close the bottom of the socket 4, where the tip of the brooch. This plug 24 fills at the same time the space under the socket 4, which has been hollowed out by the tip of the pin 29 (FIG. 7C). This plug 24 will be pierced with one or more holes 24 '(FIG. 7D), to allow air to pass, during its installation and possibly, to also allow some future roots to pass. The sleeve 4 is filled with the material 7 of the future roots (molten plastic, or glue, or polymerizable material, or ...) and this material 7 is expelled with the element making the piston Pi, (element which can be part of the sealing post). The material 7 escaping through the slots 2 or holes 3, becomes roots and strata. We remove the piston element Pi if it is not part of the stake and we introduce the latter which can stick with the residual material which remains at the bottom of the socket, or be pressed in force.
SCELLEMENT D'UN PIQUET EN SOL TENDRE Le principe est pratiquement le même que précédemment, sauf que la douille 4 est enfoncée telle quelle, par sa propre rigidité, sans broche, éventuellement poussée mécaniquement par un vérin 21 (FIG. 8), ou tout autre moyen. La douille 4 qui n'est pas traversée par une broche aura sa base bouchée d'origine, comme dans la FIG. 7D, et même remplie de la matière des futures racines, avant enfoncement. Ensuite, toujours avec un vérin, ou un martyre, ou avec la base du piquet s'il est équipé pour, on expulse la matière etc..SEALING OF A SOFT STAKE The principle is practically the same as before, except that the socket 4 is inserted as it is, by its own rigidity, without spindle, possibly mechanically pushed by a jack 21 (FIG. 8), or all other way. The socket 4 which is not crossed by a pin will have its original plugged base, as in FIG. 7D, and even filled with the material of the future roots, before sinking. Then, always with a jack, or a martyr, or with the base of the stake if it is equipped for, the material is expelled etc.
Des stries ou des rainures, ou carrément des creux, sont prévus sur la surface des éléments/piston Pi, pour que les racines restent en contact avec l'intérieur de la douille, et maintiennent cette dernière. On peut utiliser un système simple, dans certains cas, à pédale (FIG. 9) pour le fonçage ou pour expulser la matière. Ce système est employé pour les blocages de porte, ou encore dans les pistolets à colle : il s'agit d'une petite lame en biais 32 (FIG. 9) qui entraîne une tige 31 à chaque poussée sur la pédale. Système parfaitement adaptable.Streaks or grooves, or squarely depressions, are provided on the surface of the elements / piston Pi, so that the roots remain in contact with the inside of the socket, and maintain the latter. A simple system, in some cases a pedal (FIG. 9) can be used for driving or for expelling the material. This system is used for door locks, or in glue guns: it is a small bias blade 32 (FIG. 9) which drives a rod 31 with each push on the pedal. Perfectly adaptable system.
Pour expulser la matière des futures racines, on peut utiliser une seringue SG, déjà évoquée, ou même un simple pistolet à colle. Par ces instruments on procède par injections racine par racine, strate par strate, au travers d'une sorte de coupelle Cle (FIG .10), enterrée près du sol, beaucoup plus ouverte qu'une douille.To expel the material from future roots, you can use an SG syringe, already mentioned, or even a simple glue gun. With these instruments we proceed by root by root injections, stratum by stratum, through a sort of Cle cup (FIG. 10), buried close to the ground, much more open than a socket.
Il est évident que l'on peut expulser la matière des futures racines autrement que par un élément/piston, par exemple avec un gaz ou de l'air comprimé, après avoir obstrué le haut de la douille, soit par un vissage soit en se servant de la collerette qui sera renforcée.It is obvious that the material can be expelled from future roots other than by an element / piston, for example with gas or compressed air, after having blocked the top of the sleeve, either by screwing or by serving as the collar which will be reinforced.
Pour certains scellements, on pourra même utiliser, après fonçage, un procédé plus percutant tel une cartouche ou une mini explosion, toujours en bouchant le haut de la douille. La pression sera violente, mais efficace et immédiate.For certain seals, we can even use, after sinking, a more impactful process such as a cartridge or a mini explosion, always by blocking the top of the sleeve. The pressure will be violent, but effective and immediate.
A UTILISER AVEC PRECAUTIONS. Dans tous les cas, il faut s'assurer de ne pas avoir de canalisations à proximité, (telles les égouts, l'eau, l'électricité, le téléphone, etc..) surtout près des agglomérations.USE WITH PRECAUTIONS. In all cases, care must be taken not to have pipes nearby (such as sewers, water, electricity, telephone, etc.), especially near built-up areas.
. Une méthode encore plus radicale est d'utiliser, toujours après fonçage, une douille longue 37 (FIG. 11), toujours bouchée en haut, dont la base est pré-découpée en lamelles 38, par des fentes longitudinales, profondes, jusqu'à la pointe de la base. Ces lamelles se détacheront les unes des autres sous l'effet de l'explosion d'une charge légère d'un produit détonant. Les lamelles 38 s' écartant de la douille (FIG.. 12) deviennent des Ersatz de "racines". On peut compléter la tenue de l'ensemble en comblant l'espace laissé par l'explosion 39 (FIG. 12), à la base de la douille, par un fluide qui se solidifierait, tel du béton par exemple.. An even more radical method is to use, still after sinking, a long socket 37 (FIG. 11), still plugged at the top, the base of which is pre-cut into strips 38, by longitudinal slots, deep, up to the tip of the base. These strips will detach from each other under the effect of the explosion of a light charge of a detonating product. The strips 38 moving away from the socket (FIG. 12) become Ersatz "roots". We can complete the holding of the assembly by filling the space left by the explosion 39 (FIG. 12), at the base of the socket, with a fluid which would solidify, such as concrete for example.
