Definitions

  • ground compaction through induced vibration can be carried out by means of vibrating systems for ground compaction operating on one or more holes in the ground.
  • the compaction of sandy-gravel soils requires the use of systems operating at low frequency, whose action produces the better possible grade of self-thickening. This is due to the fact that the typologies of granulated soils, subject to vibration, tend to self-thicken.
  • the system can be hanging from a cableway exavator or directed along a mast (guiding tower).
  • Both the piling and the ground compaction are favored by water jets adjustable in flow rate and pressure, whose supplying is carried out through pumps and dedicated lines within the system itself.
  • the compaction is carried out from the bottom upwards, with fixed rising intervals and treatment times.
  • the filling ground also known as carried inert material, is inserted by the opening of the hole (generally with a conical opening) with the aid of operator means, such as gummed blades.
  • operator means such as gummed blades.
  • the final result of the treatment depends on the right choice of the compaction system, adapted to the type of ground present in the place of operation.
  • the action of a thrusting winch causes an optimal compaction of the column and an in-depth extension of the thickening further than the maximum reached depth.
  • the column of compacted inert material within the hole in the ground is then formed by subsequent steps of extraction, output and compression of the inert materials both downwards and laterally in the ground. In this way columnar elements which, by interacting with the ground, support the loads, can be obtained.
  • the two systems of vibro-compaction previously described comprise the loading of a movable hopper upon the guiding tower which brings the inert material (generally gravel with different particle size) from the basis height wherein it is loaded by the gummed blade, up to the top of the system itself.
  • the inert material generally gravel with different particle size
  • the mode with which the inert materials are inserted within the vibrating tool takes generally place by overturning the hopper.
  • the system presents an operating machine equipped with a guiding vertical tower, to which is constrained a drill battery provided with an ending vibrating tool (vibro) of ground compaction and, sometimes, with a container arranged on the upper part of the vibro. To the latter, it is fixed a "hook"-type mechanical coupling, which acts as seat upon which a roller integral with the hopper slides and which constrains the structure to the overturning.
  • a device for the supply of inert materials to vibrating systems for ground compaction is made as claimed in the first claim.
  • Equipment 20 for ground compaction 100 comprises:
  • an air compressor 40 In a rear part of operating machine 21, opposed to the part upon which is constrained tower 22, is present an air compressor 40, needed for permitting the carrying out of the vibro-compression technology of the equipment.
  • Device 10 which is present in the form of a hopper, is constrained to tower 22 through a plurality of guides 41, arranged in parallel to tower 22 itself and along which slides a double basket frame 50, fixed to plates 16, 17 of body 10 of the device; in detail plates 16, 17 are of removable type.
  • the top of drill battery 22a finds at different heights and it is not defined a position of unique charge, but only a relative one.
  • leverage system 14, 14b, 15 actuated by the same hoisting arrangement of the hopper, automatically activates the opening of door 11 and the consequent exit of the inert material.
  • excavation equipment 20 is a crane provided with an inclinable arm 50 (of lattice shape, as shown in figure, or telescopic, not shown) and fixed upon a first end of operating machine 21 and having upon a second end a plurality of pulleys 51, 31 upon which slide the traction ropes which hang drill battery 22a.
  • inclinable arm 50 of lattice shape, as shown in figure, or telescopic, not shown
  • the second end of arm 50 possesses also an extension directed outwards (technically known with the name of derrick), upon which is present a further pulley 52, upon which slides a traction cable 60 of device 10 independent from the traction rope of drill battery 22a.
  • Device 10 is fixed in such a way as to, when drawn by traction cable 60, proceed along a vertical path parallel to the direction detected by drill battery 22a.
  • the opening of door 11 is exerted by the inner pressure of the inert materials contained in the hopper, which, laterally exiting, find a simple escape way in the passing from the hopper to caisson 23.
