Definitions

  • the present invention relates to a device for trench support.
  • a support of a trench intended to receive elements to be buried and comprising two cladding panels intended for be placed opposite against the walls of the trench.
  • Such a device can be used for the trench support intended for the installation of various elements such as pipes or pipelines. He finds his application in particular in laying lines of armored electrical transport.
  • the object of the invention is to provide a device for support allowing the cladding of the trench step by step as the trench is dug, while also participating in the subsequent installation of the elements to bury it in the trench.
  • the gantry includes a support and lowering of the element to be buried.
  • each upright has two legs fixed to the corresponding panel by pins and threaded each in two U-shaped irons secured to the panel and carried each at their lower end by an angle secured to the panel.
  • the spacer arrangement has a pivoting vertical bar on each panel in two rings integral with the panel and supporting two substantially horizontal bars of substantially length equal to half the width of the trench, both vertical bars being arranged opposite when the siding panels are in place.
  • Figure 1 is a perspective view of a device according to the invention.
  • Figures 2 to 4 are views in longitudinal section a construction site for the installation of a transmission line electric shielded in a trench using devices support according to the invention.
  • the support device 1 has two cladding panels 2, 3 intended to be arranged opposite against the walls of the trench.
  • the gantry 4 for support and installation of cladding panels 2, 3 in the trench comprising two uprights 5, 6 fixed respectively to each removable panel and connected by a cross horizontal 7.
  • the gantry 4 comprises a device for support and lowering of the element to be buried fixed to the cross member 7 and advantageously consists of a hoist 8.
  • This hoist 8 supports a cradle 9 intended to receive the element to lay at the bottom of the trench, for example a pipe or pipeline.
  • the gantry can also be suspended from a carrier such as a crane thanks to a carrying ring 10.
  • Each upright 5, 6 has two legs 51, 52, 61, 62 fixed to the panel 2, 3 corresponding by pins 53, 54, 63, 64. Each of these legs is threaded in two U-shaped irons 31, 32 secured to the corresponding panel 3 and carried at its lower end by an angle 33 secured to the panel 3.
  • the device 1 also has an arrangement removable spacer comprising at least one spacer pivoting about a vertical axis supported by at least one of the cladding panels.
  • this arrangement has on each panel 2, 3 a vertical bar 11 pivoting in two rings 12, 13 integral with the panel 3 and supporting two substantially horizontal bars 14, 15 of length substantially equal to half the width of the trench, the two vertical bars 11 being arranged in opposite when the cladding panels 2, 3 are in square.
  • Actuating rods 16 are provided at upper ends of the vertical bars 11. So by pivot, the horizontal bars 14, 15 are either arranged against the cladding panels 2, 3 in their inactive position, either arranged perpendicular to the cladding panels 2, 3 in their active position. In this last position, the horizontal bars of the first panel 2 abut against those of the second panel 3 and by their mutual pressure forms two spacers between cladding panels 2, 3.
  • the cladding panels 2, 3 advantageously have their edge lower provided with anchor peaks 17. Furthermore, in order to allow the alignment of the cladding panels 2, 3 with those 2 ', 3' of the adjacent device, they include a socket plate 18, 19 welded on one of their edges lateral.
  • FIGS 2 to 4 represent a construction site place of an armored electrical transmission line in a trench, for example an electric line as described in French patent application No. 92 06 733 (FR-A-2 692 084) filed by the Applicant.
  • This type of laying step by step is particularly intended for rough terrain for example urban or rocky.
  • trench 22 is dug at using a digging machine, for example a backhoe 21.
  • the junction zones 23 are first of all prepared, formed of a concrete tank to allow possible intervention in these areas.
  • a machine lifting for example a crane 24 sets up at the bottom of the trench 22 of the support devices 1.
  • these devices 1 are supported by their gantry 4 and once installed their spacer arrangement is put in its active position and the gantry can be removed.
  • a mobile workshop 25 is brought to the trench 22.
  • Y is carried out the assembly of line sections 26 step by step, these sections being gradually suspended from the gantries 4 rested step by step on the siding panels in place. This operation is continued up to the junction area 23 next.
