Definitions

  • the present invention relates to a bridgehead for retaining a nozzle and soil in a ditch at a transverse passage of the latter.
  • a bridgehead for retaining a nozzle and soil in a ditch at a transverse passage of the latter.
  • Such a bridgehead is placed in a ditch, in two spaced copies, arranged symmetrically, to contain between them a nozzle which ensures the continuity of the flow of water in the ditch and to also retain the earth which covers this nozzle in order to constitute a transverse passage to the ditch.
  • Bridge heads are already known comprising a transverse wall having a passage opening for receiving one end of a nozzle, and a lateral channel having a wall fixed to the wall and partially surrounding the opening to ensure continuity of the water stream. between the nozzle and the ditch in which the bridgehead is placed.
  • a bridgehead is described in particular in document FR-A-2,528,885.
  • This type of bridgehead has the disadvantage of being relatively fragile, in particular under the pressure of the earth or during a small impact, the wall tends to crack vertically. A piece of the wall then risks falling into the ditch, which subsequently leads to a fall in the ditch of part of the earth constituting the transverse passage. Such an event simultaneously causes the deterioration of the transverse passage and the partial filling of the ditch, which causes an accumulation of water in the ditch unfavorable for a good state thereof.
  • An object of the present invention is to provide a bridgehead having a particularly resistant structure in order to avoid the problems posed by existing bridgeheads.
  • a bridgehead for retaining a nozzle and soil in a ditch at a passage transverse to the latter comprising a transverse wall having a passage opening for receiving an end of '' a nozzle, and a lateral gutter having a wall fixed to the wall and partially surrounding the opening to ensure continuity of the water line between the opening and the ditch, in which the low wall has at its upper part a transverse beam projecting towards the lateral gutter, and the wall of the lateral gutter joins the beam transverse.
  • the wall of the lateral channel and the transverse beam constitute a continuous frame all along the edge of the wall and therefore form therewith a particularly resistant rigid box, both to the push of the earth forming the transverse passage and to the shocks to which the bridgehead can be subjected when moving vehicles on the transverse passage.
  • the bridgehead comprises fins projecting from the external surface of the lateral gutter.
  • these fins are anchored in the earth of the ditch and the resistance of the bridgehead a displacement under the effect of the thrust of the earth is further improved.
  • the bridgehead comprises hooking rings fixed to the wall on a face facing the lateral gutter.
  • the bridgehead can be lifted by hooks passed through the rings and it assumes a position of equilibrium favorable for easy installation in the ditch.
  • the bridgehead according to the invention comprises a low wall 1 having a passage opening 2 for receiving one end of a nozzle, and a lateral channel 3 in the shape of a U, one edge of the wall is attached to the wall 1 and surrounds the opening 2 on three sides.
  • the low wall 1 comprises a transverse beam 4 projecting towards the lateral gutter relative to the face of the low wall 1 facing this gutter.
  • the wall of the lateral gutter has a progressively decreasing width from the base towards the top of the wall but always retains a width at least equal to the width of the projecting part of the beam 4 relative to the face of the wall 1 and joins the beam transverse at its ends.
  • the wall of the gutter 3 and the transverse beam 4 form a frame attached to the wall 1 and the assembly therefore forms a rigid box.
  • the bridge head comprises on either side of the fins 5 projecting from the external surface of the lateral gutter and arranged in the plane of the wall 1.
  • the fins 5 are preferably arranged at the base of the head bridge so that when the bridgehead is placed in the ditch, they dig in the banks of the latter grooves in which they are anchored and therefore resist the pressure of the earth forming the transverse passage between two bridgeheads.
  • the bridgehead also includes hooking rings 6 fixed to the wall on a face facing the lateral gutter and which can be used to raise the bridgehead for its placement in the ditch.
  • the attachment rings 6 are preferably arranged in the vicinity of the upper part of the bridge head so that the bridge head takes a position of favorable equilibrium when it is raised.
  • the bridgehead can be made of different materials, it will preferably be obtained in one piece by concrete molding, the attachment rings 6 being suitably placed in the mold so that a part is embedded in the concrete during of the casting of it.
  • FIG. 3 illustrates an alternative embodiment in which the opening 2 is a square opening while the embodiment in FIG. 1 comprises a circular opening, the general structure of the bridgehead being moreover identical to that which has been described in About Figures 1 and 2.
  • the invention is susceptible of variants which will appear to a person skilled in the art.
  • the bridgeheads shown have an opening of given dimensions, provision can be made to make the bridgehead according to the invention by partially or completely closing the opening 2 with a web of thickness less than that of the wall and / or comprising breaking points allowing the size of the opening 2 to be easily adapted on the site to the size of the nozzles which must ensure the continuity of the water stream under the transverse passage.
