Abstract
Description
L'invention concerne des dispositifs mécaniques assujettis à des engins dénommés "fusées" contribuant à la rupture (ou au refoulement) de canalisations enterrées sans l'ouverture de tranchées; en vue de permettre l'introduction concomittante d'une nouvelle conduite dont le diamètre est supérieur ou égal à l'ancienne canalisation... The invention relates to mechanical devices subject to devices called "rockets" contributing to the rupture (or backflow) of buried pipelines without the opening of trenches; to allow the concomitant introduction of a new pipe whose diameter is greater than or equal to the old pipe ...
ou encore d'un fourreau destiné à recevoir des conduites de toute nature.or a sheath intended to receive pipes of all kinds.
Autour des années 1965/1970, sont apparus, dans la gamme des matériels de travaux publics, des engins permettant de forer par compactage directement dans le sol selon des directions horizontales, verticales ou inclinées. Around the years 1965/1970, appeared in the range of public works equipment, machines making it possible to drill by compaction directly in the ground in horizontal, vertical or inclined directions.
Ces engins sont généralement auto-propulsés à partir d'un groupe moto-compresseur à air, et alimentés généralement par des tuyaux flexibles de longueur appropriée aux forages à réaliser. These machines are generally self-propelled from an air-compressor motor group, and generally supplied by flexible pipes of length appropriate to the drilling to be carried out.
Le principe de fonctionnement de ces engins fait appel au principe d'inertie après avoir pris leur propre appui sur les parois du forage, parois elles-mêmes compactées et permettant d'agir sur le corps de l'engin. The operating principle of these devices uses the principle of inertia after having taken their own support on the walls of the borehole, walls themselves compacted and making it possible to act on the body of the device.
L'usage le plus répandu de ces engins concerne surtout le forage horizontal selon des diamètres variables adaptés au type d'engins de 40 à 450 millimètres. The most widespread use of these machines mainly concerns horizontal drilling according to variable diameters adapted to the type of machine from 40 to 450 millimeters.
Nous rappelons que, faute d'une normalisation codifiée, les engins sont couramment appelés "fusées" dans le langage des utilisateurs. We recall that, in the absence of codified standardization, devices are commonly called "rockets" in the language of users.
L'innovation objet de la présente demande tient- à l'adaptation d'accessoires innovants reliés par des systèmes d'accouplement méca nique, de type classique et connu, aux engins auto-propulseurs. The innovation which is the subject of the present application is due to the adaptation of innovative accessories connected by mechanical coupling systems, of the conventional and known type, to self-propelled vehicles.
Ces "accessoires" permettent de réaliser de nouveaux travaux dans des conditions optimales pour la rupture par fragmentation de matériaux cassants, telles que tuyauteries de V.R.D. installées dans le sol. Ces tuyauteries peuvent être d'adduction en fonte grise, amiante ciment, béton, grès, plastique, etc... de tous diamètres.These "accessories" allow new work to be carried out under optimal conditions for breaking by fragmentation of brittle materials, such as V.R.D. installed in the ground. These pipes can be supplied in gray cast iron, asbestos cement, concrete, sandstone, plastic, etc. of all diameters.
Les accessoires selon l'invention permettent d'obvier à la technique de fragmentation dans laquelle un câble de traction auxiliaire relié à l'engin est introduit préalablement dans l'orifice du tuyau à fragmenter, ledit câble étant connecté à un système de treuil placé à l'extrémité du tronçon à opérer. The accessories according to the invention make it possible to obviate the fragmentation technique in which an auxiliary traction cable connected to the machine is introduced beforehand into the orifice of the pipe to be fragmented, said cable being connected to a winch system placed at the end of the section to be operated.
L'invention permet une amélioration considérable des conditions de chantier en utilisant des accessoires comprenant un dispositif fixé à l'avant d'une pièce porte-lames. The invention allows a considerable improvement in site conditions by using accessories comprising a device fixed to the front of a blade-holding part.

accessories associated with a machine.
1) Le dispositif "anti-recul" (figures 1 et 7) permet en effet de prendre un appui temporaire, lors de l'opération, à l'aide de mors mobiles (i) s'auto-bloquant sur les parois internes du tuyau à fragmenter (2), et permet ainsi au porte-lames d'opérer avec toute la puissance de l'engin auto-propulseur. 1) The “anti-recoil” device (FIGS. 1 and 7) makes it possible to take temporary support, during the operation, using mobile jaws (i) self-locking on the internal walls of pipe to fragment (2), and thus allows the blade holder to operate with all the power of the self-propelling machine.
La géométrie des mors mobiles (fig. 6) permet un positionnement "arrêt" par le truchement d'un fourreau (3) contenant un ressort (4) de force appropriée. The geometry of the movable jaws (fig. 6) allows positioning "stop" through a sheath (3) containing a spring (4) of appropriate strength.
L'ensemble des mors (1) du dispositif "anti-recul" est disposé en couronne (fig. 4). The set of jaws (1) of the "anti-recoil" device is arranged in a crown (fig. 4).
L'ajustement des mors à chaque diamètre nominal s'effectue par simple pression sur le fourreau (3) avant l'introduction de l'en- semble "anti-recul" (fig. 1) dans la conduite à fragmenter. The jaws are adjusted to each nominal diameter by simple pressure on the sheath (3) before the introduction of the "anti-recoil" assembly (fig. 1) into the pipe to be fragmented.
Le diamètre de la "couronne" (fig. 4) est voisin du diamètre nominal de la tuyauterie à détruire. The diameter of the "crown" (fig. 4) is close to the nominal diameter of the piping to be destroyed.
2) Le dispositif porte-lames (5) ou porte-couteau (6), ou porte griffes(7) est assemblé (fig. 7) par accouplement à la partie avant (8) du dispositif "anti-recul" et à la partie arrière (9) de l'engin par superposition concentrique d'une pièce d'élargissement, dont le rôle est de repousser à la périphérie les éclats de fragmentation (10). Le porte-lames, solidaire de l'engin auto-propulsé, avance avec l'engin dans le boyau à fragmenter. 2) The blade-holder (5) or knife-holder (6) or claw-holder (7) device is assembled (fig. 7) by coupling to the front part (8) of the "anti-kickback" device and to the rear part (9) of the machine by concentric superposition of a widening piece, the role of which is to repel the fragments of fragmentation (10) at the periphery. The blade holder, integral with the self-propelled machine, advances with the machine in the hose to be fragmented.
Le même "porte-lames" peut être équipé de "porte-griffres" (7). The same "blade holder" can be fitted with "scratch holders" (7).
Dans ce cas, la tuyauterie à remplacer est griffée à sa partie arrière et refoulée vers l'avant par la force de la machine.In this case, the piping to be replaced is scratched at its rear part and pushed back forward by the force of the machine.
Le montage des diverses pièces est conçu pour permettre une combinatoire de positionnement, I 'élargisseur étant en amont ou en aval de l'engin selon les besoins du chantier. The mounting of the various parts is designed to allow a combination of positioning, the expander being upstream or downstream of the machine according to the needs of the site.
