Definitions
- the invention relates to a method and a device for producing in situ columns of stabilized and compacted soil.
- Improving the stability or the bearing capacity of low-quality movable land, for the creation of foundations, embankments, embankments, etc. by building up columns of stabilized soil is a known technique.
- the columns of stabilized soil are arranged, grouped, combined according to configurations such as walls, spurs, grid, blocks, etc ... according to the desired result, but the basic constituent column is, in general, in the form of '' a soil cylinder in place whose geomechanical characteristics have been improved by the incorporation of an external material.
- an elementary column is obtained by driving a rotary drilling tool into the ground.
- This tool breaks up the ground and mixes it with a filler material introduced wet or dry through a hollow drive shaft. Once the desired depth has been reached by the tool, the tool is removed.
- the filler material mixed with the soil in place is, in general, a binder giving rise to a setting phenomenon leading to the formation of a soil concrete whose resistance depends on the characteristics of the soil, the quantity and the nature of the incorporated binder, the degree of homogeneity and the compactness of the mixture thus produced.
- the two characteristic elements determining the quality of the result obtained are therefore the homogeneity and the compactness of the mixture.
- the good distribution of the binder in the mass of the treated soil requires the complete reworking of the latter by the effect of the disaggregating tool so as to destroy as much as possible the existing links between the constituent particles of the soil and thus be able to achieve an intimate mixture between these and the incorporated binder.
- the structure of the final mixture obtained is generally looser than that of virgin soil, the destructuring of the latter by the disintegrating tool resulting in an increase in volume. This reduction in the compactness of the treated soil contributes to lessening the consolidation effect resulting from the incorporation of the binder.
- the object of the invention is to provide a method and a device which make it possible, while ensuring a better degree of homogeneity of the solidifying mixture, to carry out the recompaction in place, thereby considerably improving the mechanical characteristics of the column of stabilized soil thus formed.
- the invention relates to a process for producing in place an elementary column of stabilized and compacted soil, which comprises a first phase consisting in driving into the ground a rotary drilling tool which disintegrates the ground and mixes it with a material contribution, and during which at least part of the disaggregated terrain is imparted an upward movement through the drilling tool, and a second phase consisting in withdrawing the drilling tool from the terrain, characterized in that uses, as a drilling tool, a device which comprises at least two parallel shafts, each shaft driving in rotation an auger, each auger being provided at its end opposite to the drive shaft with a disaggregating drilling head and the distance between the axes of the augers being less than the diameter of an auger, the shafts and barrels of the augers comprising a bore connected to a source of filler material and at least one communicating orifice with said bore being provided on the barrel of each auger for discharging the filler material, the augers being of opposite pitch and being rotated in opposite directions and which further comprises means for a drilling
- the invention also relates to a device useful for carrying out the method of the invention, which comprises at least two parallel shafts, each shaft driving in rotation an auger, each auger being provided at its end opposite the shaft of drive of a disintegrating drill head and the distance between the axes of the augers being less than the diameter of an auger, the shafts and barrels of the augers comprising a bore connected to a source of filler material and at least one orifice communicating with said bore being provided on the barrel of each auger for discharging the filler material and allowing its mixing with the disaggregated ground, the augers being of pitch opposite and being driven in rotation in opposite directions, and which further comprises means for reversing the direction of rotation of the augers.
- the soil in place disintegrated by the drilling head is driven in an upward movement through the device of the invention thus completing the disintegration effect due to the head itself and ensuring consequently a better dispersion in the mass of the ground of the material or binder of filler introduced by dry or wet way.
- the disaggregated soil passed through the entire device of the invention as the latter penetrated into the ground. Taking into account the increase in volume caused by the disintegration, there is a phenomenon of expansion accentuated by the addition of the filler material, a more or less significant part of the soil thus homogenized and mixed with the filler material which can leave at the top of the column. If desired, this first phase can be repeated one or more times.
- the second compaction phase once the depth fixed for processing has been reached, the direction of rotation of the auger elements is reversed, causing the material to reverse movement as the device of the invention is withdrawn.
- the continuous recompaction of the terrain-filler material mixture by the device is thus carried out throughout its ascent to the surface.
- the part of the ground extracted during the drilling phase is reintroduced into the drilled column.
- the recompaction effect usually requires supplementing the filling of the drilled column with an addition of additional material.
- the method of the invention can be implemented in both coherent soils (clayey soils, clay, etc.) and non-coherent ones (sand, gravel, etc.).
- the device represented in FIGS. 1 and 2 and used to produce columns of stable and compacted soil according to the method described above comprises the following elements:
- Each auger is provided at its free end with a disaggregating drilling head 3 adapted to the nature of the ground. It can be, for example, as illustrated, a helical head, or a knife.
- the distance X between the axes of the augers is less than their diameter so that the turns of the two augers are effectively engaged one in the other so as to ensure a movement or forced flow of the disaggregated ground 4 by the two augers.
- each auger also has a bore 5a which communicates with the bore of the corresponding drive shaft, thus making it possible to bring the filler material or binder dry or wet to orifices 6 arranged on the height of the barrel of each auger so as to ensure intimate mixing with the disaggregated soil.
- the length of the augers is adapted to the depth of the column to be produced. It is generally between 1/4 and 1/2 of the length of the column but it could, in certain cases, be increased until reaching the same length.
- augers instead of having a continuous helical profile, could be discontinuous, that is to say be replaced by a plurality of spaced propellers.
- a number of double bearings 7, depending on the depth of the column to be produced, are distributed over the height of the drive shafts and augers so as to maintain their parallelism.
- bearings could be replaced over the height of the drive shafts by a hollow continuous beam which could possibly be used to bring the material or filler binder at the top of the augers.
- the two drive shafts 1 are mounted on a gear reversing reduction device 8, itself connected to a motor 9, which drives them as well as the augers, rotating in opposite directions and at the same speed.
- This motor-reduction unit 8-9 can be carried by a drilling machine (not shown) installed on the surface in line with the column to be produced, either by means of a slide on which it can move longitudinally either freely or by through a translation device. Alternatively, it can be suspended from the boom of a lifting device (crane or other).
- the carrier being installed at the right of the chosen location, the shafts and augers are rotated in the direction corresponding to the screwing of the augers in the ground ( Figures 1 and 3).
- the speed of penetration is controlled so as to optimize the effect of soil disintegration.
- the filler material or binder can be introduced at any time during the drilling operation. In the case of the wet route it is pumped by a pump located on the surface through the rotating heads 10 mounted at the end of the drive shafts. In the case of the dry route it is forced using compressed air through the same heads.
- auger bores constitute independent conduits, it is possible, if desired, to feed one of the bores with a different filler material than that feeding the other bore, in order to react these materials in situ together or with the ground.
- the invention makes it possible to obtain columns of stabilized and compacted soil whose mechanical properties are very much superior to those of the columns obtained according to the prior art, without recompaction.
- a particularly interesting application of the method and the device of the invention is the stabilization of the rights of way of railway tracks.
