Definitions

  • the present invention relates to the field of materials clay with the presence of pebbles, especially spoil from earthwork. It relates more particularly to a method of treatment intended to mix a material of this type with one or several additives and it also concerns an installation specially designed for the implementation of said method, known from document EP-A-0 560 222.
  • a shaft mixer horizontal which mixes the clay material and the additives previously distributed on the ground in the form of strips of a given width.
  • the goal set by the applicant is to propose a process which overcomes the drawbacks of current techniques with regard to concerns the re-use of earthmoving cuttings.
  • This process is not however not limited to excavation but can see its applications to any material which mainly contains wet clay which we want to mix with at least one adjuvant.
  • the addition of the adjuvant is carried out using a dispenser in an amount which depends on the height of the layer material and the frame rate of the element drive.
  • the choice and percentage of adjuvant is determined in depending on the end use which is envisaged for the product obtained. The same applies to the conditions of use of the rotor blades. whose action aims not only to achieve a homogeneous mixture of material and the adjuvant but also to refine the particle size of the material.
  • the adjuvant used is in particular lime and the conditions for implementing the rotor are such that allow to obtain a treated material having a particle size maximum of 50mm.
  • the conditions of implementation of the rotor are such that they make it possible to obtain a treated material having a maximum particle size of 30mm.
  • the height of the layer formed on the drive element was of the order of 10 to 50 cm
  • the amount of adjuvant added to the layer before entering the enclosure was of the order of 0.1 to 5% by weight relative to the material
  • the rotor rotation speed was between 160 and 200 rpm with element moving speed between 200 and 1000 meters / hour.
  • water is added, preferably by spraying, before and / or after and / or when submitting, in the enclosure, the material and the adjuvant to a mixing and grinding treatment by the action of a rotor.
  • the planar element drive consists of a tile chain, particularly effective in the case where the material to be treated consists of spoil from earthmoving with a high proportion of wet clay, having tendency to form compact and sticky blocks.
  • the current invention is however not limited to the use of such a chain with tiles; it indeed possible, in the context of the present invention to use any other type of flat and rigid conveyor element or comprising a flat and rigid area such as for example a floor vibrating or a floor comprising a scraper ensuring the advancement load; in the latter case, the method of the invention is used implemented discontinuously.
  • the means of adding the adjuvant are, in a variant of embodiment, consisting of a metering device arranged transversely above of the element training plan, before the entry opening of the enclosure and able to distribute the adjuvant in the form of a layer of substantially uniform determined height.
  • the means of additive are constituted by a dispenser able to dispense the adjuvant inside the enclosure by a hole made nearby of the entrance opening thereof.
  • Earthworks cuttings can contain up to 80% wet or even very wet clay in the case where the water table is close to the ground where earthworks are carried out.
  • the objective of the present invention is to create a site for treatment to which the materials from the earthworks to be stored in a building for drying natural then treated. The material thus treated is then stored for sale or delivered directly to the site by boat or truck. The treatment must allow to obtain that the material from earthworks either homogeneously mixed with one or several adjuvants, and has a given maximum particle size.
  • a first outlet for the treated materials can consist in their use for embankments or for form layers for road.
  • it can be silt or clay treated with as an additive to lime and / or hydraulic binders.
  • Another outlet may consist in the use of treated materials, in a substantially impermeable layer, for technical landfill centers. In this case, we use as bentonite adjuvant.
  • Figure 1 attached includes as a drive element comprising at least a given portion forming a flat surface and rigid, a tile chain 2, which is stretched between two wheels 3 and 3 ', a idler 3' upstream and a gear 3 downstream which is driven to move in the direction of arrow F by means not shown.
  • a hopper 5 for storage and supply of a material 6.
  • the lateral uprights 7 of the hopper 5 come almost into contact with the upper strand 4 of the chain 2 with the exception of the amount 7 a , most downstream relative to the direction F of movement of the chain 2, the lower edge 8 is at a distance h from the upper strand 4 of the chain 2, which distance h is adjustable manually or automatically.
  • the free space between the lower edge 8 of said lateral upright 7 a and the strand 4 constitutes the feed orifice 9 of the hopper 5, which allows the constitution of a substantially uniform layer 10 of the material 6 during the movement of the chain 2.
  • a treatment enclosure 11 Towards the downstream part of the upper strand 4 of the chain 2 is provided a treatment enclosure 11. This enclosure 11 is disposed above the upper strand 4. It is closed by a cover 12 which has an inlet opening 13 and a outlet opening 14. Inside the enclosure 11 is mounted a rotor 15, rotating about an axis of rotation 16 mounted parallel to the tiles forming the upper strand 4 of the chain 2 and transverse to the direction of displacement F. The periphery of this rotor 15 is equipped with blades 17, mounted radially. The height of each blade 17 is determined so that the end edge 17 a of a given blade comes substantially flush with the upper strand 4 of the chain 2 during its rotation. The direction of drive of the rotor 15 is produced in the direction of the arrow G, which is in the opposite direction relative to the longitudinal direction F of movement of the chain 2.
  • the drive element forms a flat and rigid surface not only at the level of the area of action of the rotor 15 but over its entire length.
  • the strand upper 4 of the tile chain 2 forms a flat and rigid surface over its entire length, i.e. from the storage hopper and supply 5 to the rotor action area 15.
  • the first metering device 18 is arranged between the hopper 5 and the treatment chamber 11. It allows the spreading of a determined quantity of adjuvant on the layer 10 of material leaving the hopper 5 through its orifice supply 9.

  • the head 20 of this second dispenser 19 opens out in a slot 21 made in the cowling 12 of the enclosure 11 to near the inlet opening 13 thereof.
  • the installation includes humidification means, in particular by spraying water on the material and / or the material and the adjuvant.
  • humidification means in particular by spraying water on the material and / or the material and the adjuvant.
  • These means which can be consist of any known humidification device and in particular of spraying can be arranged upstream of the rotor 15, which allows to moisten either the layer 10 of materials 6, or the layer adjuvant, downstream of the rotor which makes it possible to moisten the mixture of materials 6 and adjuvant or else at the level of the rotor 15 itself.
  • the operation of the installation 1 is as follows.
  • the materials 6, from earthworks, are stored in the hopper 5. Depending on their origin, said materials can be screened beforehand using the screen 22 shown schematically above the hopper 5. Due to the continuous movement of the tile chain 2 in the direction of arrow F, the materials which are in contact with the tiles of the upper strand 4 of the chain 2 are caused to move and form a substantially uniform layer 10, leaving the hopper 5 through the feed orifice 9, over a height h , the upper edge 8 of the transverse upright 7 a somehow forming a scraper.
  • the first dispenser 18 spreads on layer 10 at least one adjuvant 23 in the form of an additional layer 24.
  • the assembly 25 formed by the layer 10 and the complementary layer 24 enters the enclosure 11 through the inlet orifice 13.

  • the materials 6 and the adjuvant 23 are lifted by the blades 17 of rotor 15 then successively thrown against the face internal 12a of the cowling 12 and against the surface of the upper strand 4 of the tile chain 2. It is this action of plating against the face internal 12a of the cover 12 and against the rigid surface formed by the upper strand 4 of the tile chain 2 which makes it possible to complete effectively the action of grinding and kneading the blades 17 of the rotor 15.
  • the second dispenser 19 In place of the first dispenser 18 or possibly in complement of it, it is possible to implement the second dispenser 19 to add adjuvant 23 or a second adjuvant 27 directly inside the enclosure 11.
  • the dimensions of the inlet 13 and outlet 14 openings of the enclosure 11 are preferably proportioned so that the incoming 25 and outgoing 26 layers act as seals so as to limit the projection of material and dust outside the enclosure by said openings 13, 14.
  • the metering device (s) 18, 19 are provided with adjustment means known either for selecting the quantity of adjuvant to be deposited on the layer 10 or to be introduced in enclosure 11 to obtain the proportion which is desired according to the intended use.
  • adjustment means can be manual or automatic, taking into account in particular the speed of movement of the chain 2 and the height h of the layer 10 of material 6 from the hopper 5. This height h can also be adjusted by manual means or automatic, not shown, for example a shutter hatch sliding along the transverse upright 7 a .
  • the processing conditions take into account the parameters that are intended for the intended use, for example as they appear from the guide entitled “Realization of embankments and form layers ”referenced D 9233-1 in the publications of LCPC (Central Laboratory of Bridges and Roads).
