Definitions

  • the invention relates to the compaction of various materials, coherent or pulverulent, in particular those used for backfilling trenches and more generally cavities containing or not buried networks (air, gas, electricity, telephone, water, sanitation). Partners involved in this area currently and unanimously recognize that the new or recent networks are too weak over time, this defect being essentially due to insufficient rates of compaction.
  • the new European regulations provide for strict controls (compaction and (or) sealing) for the reception of networks: it is therefore imperative that companies can build good quality networks.
  • compacting machines are used which work on the surface of embankments, such as rammers, vibrating plates and rollers.
  • the object of the invention is to guarantee optimal compaction and of the same intensity on the entire depth of the embankment, both for powdery (granular) soils that coherent, or of intermediate type, by simple mechanical action and without addition of consolidation products, while allowing rapid backfilling by a single layer, the trench being completely filled with non-densified material over its entire width and thickness before starting the compaction phase.
  • the element helical is a flat propeller with a single turn developed over substantially 360 °, flattened, and the underside of which is smooth, the upper face being equipped with a device (described later in detail) allowing the collapse of the vaults which may form during compaction of cohesive soils, especially clay soils.
  • This propeller is fixed at the base of an axis that can rotate in both directions and it is subject to the combined action of three mechanical actions: vibrations at vertical component, threshing by a sheep, and weight of the set of mobile equipment.
  • the finger (10) causes the collapse of the vault (11) not yet compacted (loose hatching).
  • the debris thus formed (12) falls on the upper face of the propeller, pass through the propeller slot and are driven (13) by rotation under the propeller where they are compacted (14) by threshing and vibrating effect (dense hatching).
  • Scraping is particularly useful when the materials to be compacted are consistent, for example clay soils.
  • scraping devices can be envisaged. They can be automatically engaged when rotating in reverse of the propeller like the scraper finger described above or be controlled remotely for example by hydraulic transmission. In this case the operator chooses to activate or not scraping depending on the type of soil to be compacted.
  • Figure 3 depicts a device for compacting trenches of different widths.
  • the compacting device used here comprises a plurality of elementary compacting devices (compacting modules) identical to that illustrated in FIG. 1 and mounted on a common chassis.
  • modules compacting devices
  • other parts of the modules can be common to all the modules or to some only: drive motor, vibrating device, anvil, sheep for example. If necessary, the positions of the different modules can be adjusted in height and / or in width.
  • This device is shown diagrammatically by its chassis (1) and two pitch propellers (2) and (3) opposite to each other, rotating in opposite directions so as to neutralize the reaction effect on the soil to be compacted.
  • the chassis (1) and the two propellers (2 + 3) are oriented in the direction of the trench, in this case, which corresponds to a width weak: two successive stations, each comprising a descent phase and an ascent phase, are then spaced about 1 meter apart, if the diameter of each propeller is 35 cm and if their axes are 50 cm apart, so that ensure sufficient compaction, taking into account the edge effect caused by each propeller at a distance at least equal to a radius, beyond its periphery.
  • the compacting device is oriented at 45 ° (position (4)) relative to the axis of the trench. The distance between the two stations is then 75 cm.
  • the device is oriented perpendicular (position (5)) to the axis of the trench. The distance between two stations is then 50 cm.
  • the angle between the axis of the chassis and the axis of the trench is then a function increasing the width of the latter.
