Definitions

  • the present invention relates to a backfilling method a trench and a device for the implementation of this process.
  • a screening and backfilling device of this type usually includes a hopper to receive materials used for backfilling, a continuous conveyor arranged below the hopper, and a sieve system vibrators fed by the continuous conveyor and intended for fill the trench with successive layers of material having a determined particle size.
  • the whole is united a frame, which itself is supported, cantilevered above of the trench to be backfilled, by an arm carrying a tractor or similar device.
  • We can thus backfill a trench, possibly by carrying out multiple passes with one device, with different layers of the same material or of grain size materials different.
  • the chassis also has the disadvantage of being cantilevered relative to the tractor.
  • the invention proposes no longer to use a self-powered backfill system, but a screening and backfilling system towed by a hydraulic excavator of a conventional type, which ensures in addition to loading the device with backfill material screening, the hydraulic excavator-device assembly screen can move as well on the cord cuttings from the trench, only on a track laid out the other side of it.
  • the invention therefore has for first object a method of backfilling a trench, in particular using spoil from the digging of this trench, this process of towing with a shovel hydraulic, parallel to the trench, a chassis mounted on wheels or on tracks, supporting a hopper of load equipped with a grid at its lower part, load this hopper with backfill using the hydraulic shovel, to transfer the material by gravity backfill through the grid on a vibrating screen placed below the hopper, then on a conveyor continuous, placed below the vibrating screen on the chassis, transverse to its direction of movement, the sieve vibrating and the conveyor being driven by means motors carried by the chassis, and to pour the material from laterally filling in the trench using the conveyor.
  • the link with the hydraulic excavator can be a simple drawbar articulated at one end on the chassis and at its other end on the hydraulic shovel.
  • the hopper is preferably pivotally mounted by relative to the chassis, at least one cylinder being provided on the frame to straighten it by pivoting with respect to this, in order to evacuate the largest constituents of the backfill material not passing through the grid.
  • This can be made up of simple bars arranged in parallel, for example parallel to the direction of movement of the device.
  • the conveyor it is preferably arranged transversely to the direction of movement of the chassis, under the stress of the hydraulic shovel which it is made united. He is also trained by at least a reversible motor, for example a hydraulic motor, so that the backfill material can be poured out right or left of the device.
  • a reversible motor for example a hydraulic motor
  • the invention finally relates to a set for backfilling a trench, characterized in that it includes a hydraulic shovel and a device for screening and spilling a material of backfill of the type just defined, this device being integral with movement of the shovel hydraulic by a connecting member such as a drawbar, so that it can be towed by the shovel.
  • the chassis of the screening device will include at each of its ends means allowing to make it integral in displacement of the shovel hydraulic, so that it can be towed by one or the other of its ends.
  • the self-propelled hydraulic excavator is designated by the reference 1
  • the device screening and backfilling towed by this excavator is designated by reference 2.
  • the shovel 1 can be of any known type.
  • the device 2 comprises a chassis 3, mounted here on tracks 4, but which could as well be carried by wheels, on which is articulated, by levers 5 and 6, a drawbar 8 articulated at its other end on the chassis of the shovel 1.
  • the lever 6 is attacked by the rod of a jack 7 carried by the chassis 3 of the screening and backfilling device.
  • This chassis 3 is linked to the structure 9 carrying the tracks 4 by a system of levers such as 10, actuable by a cylinder 11, so as to be able to maintain the chassis in a horizontal position whatever the inclination of the ground on which the tracks 4.
  • a hopper 12 one end of which adjoins the shovel 1 is pivotally mounted relative to the chassis 3 under the actuation of jacks 13, receives from shovel 1 the raw materials for backfilling the trench 14 (see Figure 4), for example in order to bury in this cut a tube 15 which is housed there.
  • the hopper 12 has a bottom part constituted by a grid 16, here made up of bars parallel arranged longitudinally and intended to retain excessively large cuttings, which can then be removed by lifting the hopper (see figure 2).
  • the material passing through this grid falls on a vibrating screen 19, placed below it, then on a continuous conveyor 17, carried by the chassis 3 below of the vibrating screen and arranged transversely to the direction of movement thereof.
  • This conveyor 17 projects laterally with respect to the chassis above the trench 14 and pours into it backfill materials.
  • the conveyor 17 is driven by two reversible hydraulic motors carried by the chassis 3. As indicated above, it can also be moved transversely using a double-acting cylinder, in order to ability to project sideways on one side or the other from the chassis, so that the material can be filling both right and left of it.
  • the various cylinders of the screening and backfill and the conveyor drive motors 17 and vibrating screen are fed and operated from a hydraulic cabinet 18 carried by the chassis 3. All of these organs are remotely controlled by a remote control placed in the excavator cabin or operated by an operator near the wiring device.
  • the invention therefore provides a simple and inexpensive to backfill trenches, since the device used for backfilling is not self-propelled, but is towed by a hydraulic excavator, which has also for the function of powering the backfilling with backfill material.
  • the two ends of the chassis 3 are substantially identical, so that the screening device 2 integral in displacement of the hydraulic excavator 1 by one or other of these ends.
  • the tracks of the screening and backfilling device can adapt to very uneven terrain and move forward for example on the cuttings 20 from trench 14 or on a runway 21 provided on the other side of this trench.
  • the hydraulic excavator-screening and backfilling is able to climb or descend slopes relatively sharp, up to 25 °.
