Definitions

  • the present invention relates to a new anchoring device with articulated element having a bent shape for any soil, easy to implement by known methods of implementation (threshing, vibrofonishing, propulsion, launching and suction in the case of loose soils ).
  • This technique is applicable both for anchoring on land and for making fixed anchor points in water, in particular in port facilities (marinas, mooring pontoons, etc.).
  • Patent FR 2,424,846 defines an anchoring system with free rotation of the attachment point, the latter being located in front of the center of gravity relative to the attacking end of the ground, but the installation of the system is done by pulling on the cable.
  • US Patent 3,282,002 presents an anchoring device with free rotation of the attachment point provided with a flat plate capable of tilting, the angular movement of this plate being limited by a stop. But this plate does not rotate by itself, it needs the help of a spring, or even an explosive, so that it blocks the anchoring.
  • the US patent. 3.888.057 defines a device where one must exert a traction on the eye of a free moving part located in the middle of the anchoring plate so that a lug perpendicular to the plate and located in the near front part from the leading end of the ground, can stand up and then tilt the anchor plate. Under these conditions and particularly in hard soils, the torque on the movable part may be too small for the device to be able to open and the plate will slip backwards without tilting.
  • the problem to be solved is therefore the following: It is a question of realizing anchor points of high resistance on land and at sea that can reliably withstand a horizontal pulling force, inclined upwards and even vertical upwards, from the ton to the hundred tons. While being capable of being positioned precisely, the anchoring system must be acceptable for all types of soil (clay, sand, rocky soil for example).
  • Anchor piles or generally groups of anchor piles generally solve such a problem, but they have the disadvantage of tearing off when the applied vertical force is too great.
  • the invention consists of a new anchoring system making it possible to solve the problem posed.
  • the forces in particular of percussion communicate to the anchoring element an energy known as of threshing.
  • the stated combination is capable of providing the best locking position for the anchoring device during the traction T exerted by the anchor line. It is adapted to make it move in the ground when it undergoes these efforts and to orient it to present an optimal master torque in order to mobilize the maximum stop of the earths.
  • master-torque is meant the outline of the cross sections to the axis of movement of the anchoring element.
  • connection By flexible connection is meant here a connection which does not introduce substantially any moment of rotation at the point of attachment to the plate, such as a connection by wire, chain, ball joint or by an articulated threaded rod.
  • the burial in the ground is carried out by driving forces F E brought into play thanks to techniques for example of threshing, vibrofonishing, propulsion, launching, even suction in the case of loose soils, all known to man. art.
  • driving forces F E brought into play thanks to techniques for example of threshing, vibrofonishing, propulsion, launching, even suction in the case of loose soils, all known to man. art. The choice will depend on the nature of the soil.
  • the angular movement of the bent articulated element may be understood from 30 ° to 60 °, and preferably close to 45 °, relative to the driving plane ⁇ .
  • the anchoring device to resist a tensile force T at all height angles (horizontal, inclined and vertical upwards) implements at least one anchoring element designated as a whole by the reference 1, which is generally driven into the ground along the vertical by one of its ends constituting its attack end of the ground 2.
  • An anchoring line 3 constituted in particular by a wire, a chain or a rod articulated thread, intended to transmit the tensile force T to be supported, by means of a traction pin 11, is attached to said element at at least one point by a flexible connection 5 such as, for example, a ball joint n ' introducing substantially no bending or twisting moment, at said point of attachment to the axis of traction 11.
  • the position of the latter on the anchoring element is chosen such that the point of application of the traction force to said element is located in front of the barycenter, or center of gravity G, of the bearing surface buried in the ground, or master torque of said anchoring element, towards said leading end 2.
  • the anchoring element is characterized by a main body comprising a rigid dorsal part 6, on which a sole plate 4 provided with deflectors 15 rests on the inner side. This rigid dorsal part supports and transmits the threshing energy up to the leading end 2.
  • this stud has a length h of 2 to 6 times its transverse dimension d. It is preferable to have a male stud to avoid any risk of jamming of the threshing element resulting from a mating phenomenon during the impact on the anvil.
  • This nipple can have any shape (square, rectangular, round, oval or diamond for example).
  • the anchoring element In its part opposite to the leading end of the ground 2, the anchoring element is equipped with a bent articulated element 9 provided with stiffeners 18 in its internal part facing the stud 8, which pivots on a perpendicular axis 10 to the axis of the anchoring element along the driving plane ⁇ to a maximum position fixed by a stop 17 defining an angular movement ⁇ from 30 ° to 60 ° relative to the axis of the anchoring element which is in the driving plane ⁇ and which passes through the stud 8.
  • the articulated element 9 has a flat part on the part of the elbow furthest from said articulation 10.
  • the part of the articulated element 9 furthest from said articulation axis 10 has a curved shape whose radius of curvature r is at least equal to the distance separating said articulation axis 10 from the ground attack end 2.
  • This articulated element which separates the articulation 10 from the free end 9a of said element is between half and a tenth of the total length of the anchoring element and particularly interesting results have been noted with a value substantially equal to one third of the total length of the anchoring element.
  • the articulated element is such that the elbow in a vertical position at the time of insertion, that is to say aligned along the sole 4 is in the shadow of the master torque of the device, that is to say of the contour of the cross sections to the axis of movement of said anchoring element.
  • the distance from the attacking end of the ground 2 to the traction axis 11 constituting the point of attachment of the anchor line 3 is between a quarter and a half of the total length of the element anchoring. Good performances were obtained when the distance was preferably equal to a third.
  • the ratio of the length of the anchoring element defined according to the driving plane ( ⁇ ) to the width of said element is between 1/3 and 10 and preferably between 1 and 5.
  • the distance from the leading end of the ground 2 to the axis of traction 11 or point of attachment is between a quarter and a half of the total length of the anchoring element and preferably equal to a third.
  • the leading end of the ground may have an asymmetrical shape with respect to the driving plane (Fig. 1A). It can also have a symmetrical shape with respect to the same penetration plane (Fig. 9).
  • a blade 16 which can for example be made of steel or plastic, which puts "in the shade” the sensitive elements of the device, in particular the bent articulated element, the anchoring line and the flexible connection. This airfoil overflows on the sole 4 in order to properly guide the movement of the anchoring element.
  • the mechanism for the abutment of underground soil is perfectly stable in meaning that there is a flow of soil material from the compressed side M C to the decompressed side M D.
  • the static anchoring resistance or permanent anchoring strength F ⁇ is perfectly stable (Fig. 5).
  • S being the area of the anchoring element
  • P1 and P2 being the pressures of the pore water at the front and at the rear of the anchoring element, S its area.
  • the anchoring resistance is limited by the driving force F of a volume of soil having the approximate shape of an inclined inverted cone situated above the system of anchoring (hatched area).
  • the device can optionally be removed from the ground.
  • it will for example be provided with at least one extraction cable or any other known extraction means, fixed at at least one point 13 on the articulated element 9 and which optionally makes it possible to extract from the ground the anchor by vertical or backward pull from the surface.
  • FIGS. 8 and 9 A particularly advantageous embodiment of the anchoring device according to the invention is illustrated by FIGS. 8 and 9. Its more compact shape, its end for attacking the ground 2 symmetrical with respect to the driving plane and its main body 6 cut in an IPN or HPN profile on which rests a larger anvil 7 allow the anchoring device, due to a smaller master torque, good burial in hard soils as well as in soft rocks and good blocking position.
  • the types of anchors according to the invention can be arranged in series or in parallel while being interconnected by anchor lines. This device then increases the anchoring force.
  • the device according to the invention is suitable for work at sea and provides a very high anchoring strength for floating or semi-floating supports whatever the ground encountered. It can keep the structure rigorously in position and also ensure the longevity of the anchoring.
