Definitions

  • the present invention relates to a method of treating dry soils sensitive to water.
  • soils with a water deficit in relation to the optimal water content must, for use in the construction of public works, in the embankment part, upper platform of earthworks, arase of earthworks, layers of pavement and pavement layers, be treated by a soil treatment process allowing the improvement and / or stabilization thereof.
  • Clays represent a family of minerals that become unstable in the presence of water; the soil then changes from solid to plastic. Clays are thus responsible for instability in built structures.
  • soil treatment is intended to mean a method of modifying the soil so that it performs the functions intended for it, in particular soil improvement and stabilization.
  • a soil treatment therefore does not include, for example, the insertion into the ground of an impermeable layer, because such an operation does not modify the soil per se.
  • soil improvement is understood to mean the water insensitivity of soils by flocculation of clays, which allows short-term circulation. term, or even immediate construction machinery and a long-term change, making the treated soil insensitive to water.
  • “Insensitivity” to water means that the soil no longer evolves towards the plastic state, when water is added later, either by natural capillarity, or by rain or flood; this avoids the passage to the plastic (pasty) state of the soil and the reduction of the lift of the soil which causes the destruction of the structure. Improvement mainly concerns embankments and soil preparation for stabilization.
  • Solid stabilization means the increase in mechanical performance for reuse in the upper layers of the structure: upper earthmoving platform, earthworks, layers of layers and pavement layers. Stabilization can be obtained on materials that have undergone the improvement phase by increasing the lime dosage, which leads to a reaction with the compounds present in the soils or of syntax in limestone soils.
  • lime represents a set of compounds that are quicklime, mainly composed of calcium oxide, hydrated or hydrated lime, mainly composed of calcium hydroxide, or an aqueous suspension made from quicklime or hydrated lime, for example milk of lime.
  • the processes known to date are treatments that are conventionally carried out with quicklime or, in the case of fine dry soils such as clayey loams, the treatment can be carried out with lime milk. .
  • the quality of the mixture obtained is also penalized by an overdose of water during the pre-humidification.
  • This overdose causes the soil to become plastic, which disrupts the circulation of earth-moving machinery and causes the formation of lime lumps, which are not distributed in the treated soil, during the mixing of the soil.
  • the spreading of powdered lime can be a generator of dust, in case of excessive wind, and require the stoppage of the building site.
  • control of the spreading is traditionally achieved by the marking of a surface on which must be spread the contents of a tanker truck.
  • the difficulty of adjusting the flow rate to the speed of progression of the truck often leads to not reaching the beacon (overdose) or to reach it before the tank is empty (underdosing). This poor control of the spread rate for a given surface results in a heterogeneous supply of lime and water on the soil.
  • the transverse distribution of the liquid is not regular over the entire width of passage of the gear.
  • the liquid is found essentially in the direct vicinity of the teeth or blades. This heterogeneity will not be corrected during the next stages of soil treatment, not even during mixing. Indeed, the mixers work the soil in the direction of advancement of the material and not transversely.
  • the document DE 94 21 169 U1 discloses a process according to the preamble of claim 1.
  • the invention aims to overcome the disadvantages of the state of the art by providing a method of treating dry soils sensitive to water, which allows burial appropriate and homogeneous treatment liquid in the soil, for its improvement and / or stabilization.
  • digging a trench or digging trenches means the formation of one or more temporary trenches, which implies loosening of the surrounding land and causes the temporary trench to collapse or collapses quickly once the treatment liquid is deposited, this subsidence allows the uniform burying of the liquid and is almost simultaneous digging.
  • horizontal groove having a second width L2 is meant a tunnel whose width is L 2 .
  • a continuous stream of treatment liquid is deposited in the horizontal groove. So in the aforementioned tunnel.
  • the method comprises a subsidence of the soil which covers the vein of treatment liquid deposited in the tunnel and the latter sinks almost immediately by its upper part, the treatment liquid being buried uniformly in the soil to be treated.
  • the process according to the invention thus allows a homogeneous lateral dispersion of the liquid since the trenches, into which the treatment liquid is introduced, are dug so that the horizontal grooves are laterally adjacent or possibly overlapping each other and that there is no dead space untreated or otherwise treated between two adjacent trenches.
  • the method according to the invention thus uses a burial system which makes it possible to introduce the treatment liquid to a predetermined depth with a regular distribution in width, which facilitates the appropriate dosage of the treatment liquid and makes it possible to limit the number of gear passages, which considerably reduces costs. Therefore, by burying the treatment liquid which may be a lime milk or an aqueous suspension based on lime, the risk of overdosing of water or suspended matter is eliminated. Indeed, the burying of a treatment liquid according to the invention can replace the stages of prior humidification, mixing and spreading lime milk, eliminates the problem of water runoff on sloping soils and in the footprints of the machines and, in this way, regulates the water content of the soil.
  • the predetermined depth of burial according to the invention is a depth of 20 to 75 cm, preferably 35 to 60 cm.
  • the method according to the invention provides a burial to a depth of 20 to 75 cm, preferably 35 to 60 cm.
  • the treatment liquid has a solid content of up to 1000 g / dm 3 , preferably about 400 g / dm 3 .
  • a liquid treatment it is possible to envisage a whitewash for example.
  • the treatment process according to the invention also makes it possible to treat with water these rocks or these pelites described above, directly from rocks having a size of up to 600 mm.
  • the process allows their disintegration with water, avoids their evacuation and their replacement by a substitute material.
  • This soil can subsequently be treated with the treatment liquid with the same landfill system.
  • the device with hollow dispensing teeth, deeply incorporates the treatment liquid.
  • the type of tooth has since been designed to allow the share part to remain at the predetermined depth, even in the presence of rocks larger than 600 mm, especially in the presence of pelites and to distribute without overflow.
  • the sufficient amounts of treatment liquid such as a milk of lime, up to solid contents of 400 g / dm 3 or even 1000 g / dm 3 , when these suspensions contain fluidizing agents.
  • the device is used for flows from 20 to 30 dm 3 / m 2 , but the flow can also easily reach 90 dm 3 / m 2 , or even up to 300 dm 3 / m 2 . This result is obtained without risk of clogging of the treatment liquid supply, or by the suspension solid or by the soil particles.
  • the unique design of the share share firstly allows to raise the large rocks to the surface of the fractional ground, thanks to its point of penetration of the soil of the type of plow of plow, this then allows their disintegration and secondly, it allows an equivalent distribution of treatment liquid in each of the teeth from the tank through the rear distributor which has an outlet having said second width greater than said first width and which communicates with said distribution channel of said support portion. This requires in particular a good balance of pressures between the feeds of the different teeth from the tank.
  • vehicle By “vehiculable” is meant that the chassis can be pushed or towed or even be automobile.
  • the device comprises a reinforcing element connecting said support part and the share part, which makes it possible to withstand any impact with rocks of a size. greater than 600 mm, in particular with pelites, as described above.
  • the frame has a frame width and the outlets of said distributing teeth connected to said frame are, in a rear view, directly adjacent to each other, said outlet orifices preferably occupying a width at least equivalent to said frame width.
  • the teeth are aligned so that the width covered by each tooth is complementary to the others and thus covers without dead zone, the entire width of the frame. This avoids the transverse variation of buried treatment liquid, encountered during treatment with conventional equipment which is not traditionally rectified by a transverse passage. It is expected that in a plan view, the distributing teeth connected to said frame are staggered, aligned in at least two parallel rows. This allows a homogeneous distribution of the treatment liquid. It is clear that the outlet orifices of the teeth can not be perfectly adjacent because of the thickness of their wall and that therefore placing the teeth staggered allows the digging of perfectly adjacent grooves.
  • the teeth aligned in two rows will remain much deeper in the ground during the advance of the chassis vehiculable. This arrangement reduces the possible lifting of the frame during the progression of the device according to the invention in a floor to be treated. For the same reason of balancing the resistance during the progression, the teeth will advantageously be 5 in number.
  • the teeth have a length to bury the treatment liquid to a depth of 20 to 75 cm, preferably 35 to 60 cm.
  • burial at the predetermined depth according to the invention and the shape of the grooves formed do not pose a problem in the event of encountering rocks of a size less than about 600 mm.
  • the rocks pass between the vertical furrows and, since the teeth do not rise, the adjacent horizontal furrows remain adjacent and the spread remains uniform.
  • the burying of the treatment liquid according to the invention is not deviated from its trajectory by blocks.
  • the type of groove makes it possible to remain at the desired depth and to dispense sufficient surface treatment liquid without overflowing the surface.
  • each distribution channel is provided with a flow control element.
  • the flow control element may be a diaphragm capable of adjusting the liquid passage section in the dispensing channel. This gives a uniform distribution of flow in all distribution channels.
  • the figure 1 is a rear view of a preferred embodiment of the device, which is not part of the claimed object, wherein the frame comprises five hollow digging teeth driven into the ground.
  • the figure 2 is an elevational view of the embodiment illustrated in FIG. figure 1 .
  • the figure 3 is a profile view of the embodiment illustrated in FIG. figure 1 .
  • teeth 1 are fixed on the frame 2.
  • Each tooth comprises a vertical support portion 3 and a horizontal plow portion 4.
  • the plough portion 4 comprises a front tip 5 ( figure 3 ) in the ground and a rear distributor 6 which has an outlet port 6a.
  • the support portion 3 of each tooth 1 comprises a distribution channel 7 and has a width L 1 which is smaller than the width L 2 of the outlet orifices of the share portion of said tooth.
  • the width L 2 is such that in a rear view ( figure 1 ), the outlet orifices 6a of treatment liquid of the distributors 6 are directly adjacent to each other. Therefore, on the chassis width, the outlet orifices 6a of the distributors 6 join to allow the deposition of a continuous stream of treatment liquid.
  • each tooth 1 thus comprises a distribution channel 7 which communicates with a reservoir (not shown) of treatment liquid via a distribution nurse 8 which allows the dosage of the treatment liquid to be identical in each tooth 1.
  • the distribution nib 8 is equipped, in the illustrated preferential embodiment, with five outlets 9 connected to a flexible hose 10 that feeds the distribution channel 7 of each support portion 3 of each hollow dispensing tooth 1.
  • the treatment liquid, coming from the reservoir arrives in the nurse 8 which distributes it between the distribution channels 7 of each tooth 1, it flows and penetrates into the horizontal share part 4 of each tooth 1, more precisely in the distributor 6, and is then brought to the outlet port 6a thereof. It is only after the passage of the outlet orifice 6a in the horizontal groove dug at the front by the share part 4 of the tooth 1 that the natural ground collapses thanks to loosening of the surrounding earth and that it comes to cover the vein of treatment liquid filed.
  • the digging sequence of the trench, deposition of liquid in the adjacent horizontal grooves and soil subsidence is done in this order as the equipment progresses. Nevertheless, because of the speed of progress, we can say that these 3 phases are almost simultaneous.
  • a reduction of the passage section in the distribution channel by a diaphragm 11 can be interposed at the inlet of the channel distribution 7 to balance the flow on each tooth 1.
  • Interchangeable diaphragms can be provided or diaphragms with adjustable sections by remote control.
  • the height of the support portion can be up to 75 cm, preferably 60 cm, and the height of the frame with respect to the ground allows the passage of blocks of 600 mm (60 cm). The blocks of 600 mm can therefore also pass between the teeth.
  • the frame 2 comprises five hollow distributor teeth 1 aligned in two rows, staggered.
  • the frame is supported by wheels 12.
  • the front row includes two teeth 1 and the rear row comprises three. This arrangement allows a better distribution of the tensile force on the frame and permanently maintain the teeth 1 in the ground.
  • a counterbalance side devices simply hooked to the frame to keep it pressed and to keep the teeth pressed into the ground.
  • the support part 3 comprises a support plate 14 and a reinforcement piece 13 fastened by suitable fastening means 15, for example, bolts, screws , nuts and the like. These fastening means are located on the support plate 14.
  • This reinforcing piece 13, the rigidity of the frame 2 and the means for fixing the teeth thereon make it possible to permanently hold the teeth in the ground and reinforce the device in order to give it sufficient resistance against the forces due to the rocks and pelites that it could possibly encounter .
  • the soc part 4 is equipped with a welded tip 5 at the front which ensures penetration into the ground. This ground penetration tip 5 is replaceable in case of wear.
  • a dry-flint, dry, compact and water-sensitive flint-clad motorway project requires the burial of lime slurry at 400 g / dm 3 to supply 30 g of water and 20 g of quicklime per kg. 12 kg of lime per m 2 and 22 dm 3 of water per m 2 .
  • This method of treatment with traditional landfill equipment required the step 2 of complementary reduction of the grinding to less than 200 mm, to avoid loss of whitewash, following the frequent lifting of the teeth of the burner.
  • the target water content is between 144 g and 177 g per kg of soil.
  • water content ranged from 119 g to 177 g / kg soil, showing some deficits in some areas.
  • a second passage of the burner leads to too high levels, between 193 g and 219 g / kg of soil.
  • a single burner passageway therefore does not achieve the desired water content. Some values are too low and do not allow to receive the platform. Work must be resumed. It should therefore be possible to increase the quantity buried at each passage
  • This traditional landfill treatment process required steps 2 and 3 to remove the pelites and add a substitute material.
  • a soil is treated for the realization of the earthworks of a motorway construction site, similar to that of Comparative Example 2 and comprising materials of the pelite type, very compact but disintegrating in the presence of water.
  • a burial of water is planned before lime treatment.
  • This treatment method according to the invention firstly avoids steps 2 and 3 of Comparative Example 2 for removing pelites and providing a substitute material. All steps 2 to 4 of Comparative Example 2 are replaced by a direct humidification of the coarse rocks by means of the equipment, framed by two compaction operations. The process according to the invention is therefore simpler, faster and less expensive, for steps 2 to 4 of the process.
  • the water supply can easily be limited to step 3, avoiding any risk of runoff while providing enough water for the disintegration of the rocks.
  • the additional water is provided by reusing the landfill equipment to add a lime milk rather than a quicklime, as in Comparative Example 2.
  • the landfill makes it possible to injecting at a sufficient depth (35 to 55 cm) a whitewash with no risk of run-off, present in Comparative Example 1, with traditional equipment. There is no water correction necessary after step 6, as is the case in the traditional solution, in steps 7 and 8 of Comparative Example 2.
  • the soil treatment method according to the invention therefore allows the on-site valorization of pelites which are initially in the form of compact rocks, traditionally not reused.
  • the method according to the invention makes it possible to scrupulously respect the desired water content over the entire width of the equipment, without dead zone (untreated zone). There is therefore no significant dispersion of the water content values according to the invention, as was the case with the traditional equipment of Comparative Example 1.
  • the water content of the soil varied from a penalty of ⁇ 2 g / kg soil, for a target of 175 g / kg
  • the method of the invention saves a burner passage (compared with Comparative Example 1). Moreover, the process according to the invention makes it possible to avoid spreading with powdered lime (compared with Comparative Example 2); it also avoids the final water correction and a mixing passage.
  • the equipment increases the mixing performance, by helping to reduce the size of the blocks in the soil, avoiding premature wear or rupture of the rotors, allowing the extraction of large blocks.
