Definitions

  • the proposed system and its variants meet these constraints. It allows high-speed anchoring in very soil types varied, in extreme climatic conditions and in difficult geographical situations. It only requires light equipment and very limited logistics.
  • the present invention relates to a pyrotechnic anchor driving system.
  • the anchoring drive by pyrotechnics is already known.
  • the concept of pyro-anchoring consists in driving into the ground a particularly metallic anchor on which a "superstructure” is “fixed”, using the energy delivered by a pyrotechnic composition, for example of the safety propellant type with high gassing.
  • the pressure generated transmits most of this energy to the anchoring element. Mention may be made, by way of illustration of the state of the art in this respect, of the anchoring driving device as known from document EP-0039654.
  • the present invention therefore relates to a system for driving an anchor into a soil by gas pressure, comprising a support intended to be kept fixed relative to said soil, a system for igniting and combustion of a composition.
  • pyrotechnic device arranged in a launching device the anchoring, characterized in that the driving-in system comprises an acoustic protector for gas expansion, that the launching member is integral with said acoustic protector, and that the acoustic protector is slidably mounted on a recoil ramp connected to the support, so as to balance the amount of movement transmitted to the anchor during firing.
  • the support is a carrier vehicle associated with means for moving the reversing ramp and the acoustic protector mounted on said ramp, from a transport position on said vehicle to a working position.
  • Deployment means may include a telescopic arm mounted on the vehicle and relative to which the recoil ramp can tilt from a transport position to a working position under the action of a jack associated with said arm.
  • the hearing protector is preferably a tube open at one of its ends intended to be facing the ground in the working position and which is provided inside towards its other end, with the aforesaid firing, combustion and launching system.
  • Said tube can be extended beyond its end intended to be facing the ground in the working position, by a flexible skirt.
  • Said tube can also comprise two half-shells articulated with respect to a main part so as to allow the opening of the tube for loading of said system.
  • the anchors may in particular comprise a penetration limiter and fins for penetration into the ground.
  • the pyro anchor system preferably consists of a pyro anchor vehicle, a supply truck transporting the anchors, this truck being fitted or not with a handling arm, anchors and gas generators, possibly a manipulator commuting between the pyro anchor vehicle and the supply truck.
  • the pyro anchor vehicle consists of ( Figure 1) a reversing ramp 1 and its hydraulic positioning system 2, a hydraulic anchor locker 3 and the firing system 4, an acoustic protector for gas expansion 5, l 'assembly being mounted on a carrier vehicle 43 adapted to the type of site.
  • the recoil ramp can be replaced by a gutter or a recoil tube; the reversing tube then acts as an acoustic protector for expansion of the gases.
  • the carrier vehicle 43 ( Figure 6) can be an all terrain vehicle equipped with a telescopic arm 32 movable in the vertical plane. This allows anchors to be driven into locations below or elevated from at the position of the carrier vehicle.
  • the invention will preferably be placed vertically, for example at the front or at the rear of the carrier vehicle. In the case of sinking larger anchors, a longer recoil ramp will generally be required. To meet the road gauge, during transport, this ramp will preferably be placed horizontally. The deployment in a vertical position will be done using mobile arms animated by preferably hydraulic cylinders.
  • Figures 1 and 2 show preferred means and mode of deployment of the recoil ramp on the pyro anchor vehicle 43 in principle.
  • the recoil ramp 1 and its anchor system are placed on a cradle 7 and linked to it by an axis of rotation 8.
  • the cradle 7 and recoil ramp 1 assembly is moved horizontally along two rails 6 fixed to the carrier vehicle. using the ramp positioning cylinder 27 such that the axis of rotation 8 is correctly positioned relative to the desired point of insertion of the anchor.
  • the reversing ramp 1 is straightened by deployment of the straightening cylinder 28 which is fixed on the cradle 7.
  • the two pads 29 allow the grounding of the reversing ramp. They are deployed by two jacks 30.
  • a launching tube of the anchor in two parts: anchor head 12 and a locker anchoring 3.
  • the anchoring head 12 provides the anchoring guide and the resistance to pressure.
  • the anchor locker 3 ensures rapid and precise gripping of the equipped anchor 9, its blocking, the precision of the launch axis and the adjustment of the height of the ground clearance before firing of the equipped anchor.
  • the anchor locker 3 in which the equipped anchor is housed consists of two jaws 9.
  • the anchor locker 3 is moved along the recoil ramp 1 by a hydraulic cylinder 21.
  • the anchor 10 is equipped with a reusable piston 11 and a reusable anchor head 12.
  • the combustion chamber 13 thus formed contains the gas generator 14 which, for security reasons, is preferably placed in this chamber at the time of loading the anchor fitted in the pyro-anchor.
  • the chamber 13 is closed by a quick-lock latch 15.
  • the gas generator 14 comprises a sealed housing 16 preferably made of composite or thermoplastic materials with or without shutter vents.
  • the structure of the gas generator can also be metallic, cardboard, composite material or manufactured using a combination of these materials.
  • the plastic materials were chosen so that in the event of a fire, the structural material is weakened at a temperature below the auto-ignition temperature of the pyrotechnic products.
  • the structure remains intact during operation of the gas generator, but it can also either burn or burst during operation.
  • the preferred solution limits combustion and operating residues and allows the use of powders with high combustion pressure without generating these high pressures in the thrust chamber. These high pressures create too strong accelerations on the anchors and dimensional constraints on the walls of the thrust chamber.
  • the neck of the combustion chamber is preferably linked to the structure of the gas generator, but it can also be linked to the structure of the housing of the gas generator in the form of an interchangeable element after a large series of launches.
  • the neck of the chamber is made up of one or more openings. These are cylindrical or convergent in order to limit the speed of gases detrimental to the performance of the gas generating system; but without departing from the scope of the invention, it is possible to use an orifice comprising in its thickness a divergent part. In particular, to allow the conditioning of all forms of propellant elements before and during combustion, a generator with multiple small orifices will be used.
  • the obturation of these multiple orifices is preferably carried out by an under-thickness of the material in line with these orifices.
  • This box contains the propellant 17 "all weather" for reasons of safety and regularity of performances between - 40 ° C and + 70 ° C.
  • other types of pyrotechnic compositions can be used.
  • FIG. 4 it has been chosen to limit the acoustic and gaseous effects of the expansion of the gases from the gas generator by using an acoustic protector 5 in which the gases are over-expanded.
  • an acoustic protector with opening, for example in half-shells 22 whose masses are balanced on each side of the anchor system. These two half-shells 22 are closed using jacks 23 after the loading of the fitted anchor 9 in the anchor locker 3. It is also possible to use an acoustic protector made of flexible materials which is raised during loading; an acoustic protector nesting in rigid elements which during loading, a rigid acoustic protector in a single element which is released by elevation along the recoil ramp and this independently of the anchor locker.
  • the hearing protector is equipped at its base with a flexible skirt 24 which ensures a certain seal at ground level despite the irregularities in the ground.
  • the anchors must be made in soils of very varied types such as sand, swamp, clay, limestone ... These anchors, preferably metallic, will be of various shapes and sizes depending on the nature of the soil and the forces applied to the anchorage pressed, see Figures 9 to 14.
  • These anchors 9 may include lateral fins 41 which improve the resistance in the ground in particular to tilting forces.
  • section profiles of the various anchors will be adapted to the nature of the terrain; they can be cylindrical, polygonal, "T”, cross, "H”, ...
  • Elements for quick fixing of structures on these anchors may be integrated or fitted; For example interlocking tube or cone, fixing lug, pre-welded bolts.
