Definitions
- New draining wall process for its production and element used.
- the invention relates to a new draining wall, a method for its production and an element used in this production.
- the draining wall technique is well known. It is a technique derived from that of the diaphragm wall to make continuous draining trenches at depths (10-20 meters and more) impossible to reach with conventional earthmoving techniques.
- the realization is done in excavation under excavation fluid and by gravelling successive elementary panels which are in communication as the progress of the building site.
- a temporary formwork which makes it possible to retain the filtering material (gravel) of the panel N during the excavation of the panel N + 1.
- This formwork is then extracted when the graveling of the panels N and N + 1 is completed on either side of said formwork.
- the current technique does not allow the continuity of the wall to be checked as it is made. This verification can only be done after evacuation of the excavating fluid over the entire width of the wall, therefore after completion thereof.
- the current technique does not allow fractional, progressive commissioning during the execution phase.
- the current technique does not make it possible to carry out localized maintenance operations such as cleaning, re-excavation for changing the filtering material without putting the entire wall under excavating fluid and therefore falling back on the preceding drawbacks.
- the current technique does not allow the installation of a continuous drainage conduit at the bottom of the wall.
- the present invention aims to remedy these problems and drawbacks by proposing a new type of draining wall.
- the present invention is based on the idea of making the draining trench panel by panel while providing means allowing subsequent communication of the constituent panels of the trench in order to make it operational. More particularly, the invention relates to a draining wall consisting of a plurality of elementary panels (P) filled with a filter material (10), characterized in that said panels are separated from each other by intermediate elements (J) molded in the ground and in that an element (2) connecting each pair of adjacent panels is embedded in the lower part of each intermediate element.
- the invention also relates to a method for producing a draining wall in accordance with the invention, characterized in that it comprises the following steps: a) carrying out boreholes or excavations El to En spaced along the course of the draining wall to be produced, these boreholes or excavations being spaced from each other by a distance corresponding substantially to the length of an elementary panel of the wall and produced under excavating fluid.
- the hardened material of the intermediate elements is cut, the excavation step (d) is carried out so that the excavation tool comes to cut the sides of the intermediate elements Jl and J2 contiguous to said trench, and the excavation step g) is carried out so that the excavation tool comes to intersect the sides of the intermediate elements J2 and J3 contiguous to said trench.
- the excavation steps d) and g) are carried out without intersecting the sides of the intermediate elements Jl and J2, and J2 and J3, respectively, the elimination of the closed end parts which can be eliminated from the embedded elements at the base of the intermediate elements being carried out in another suitable manner, for example by a means or tool provided in the perennial central part of the tubular element or introduced into it from the ground.
- the material constituting the intermediate elements need not be cut, of course.
- the method may further comprise the laying of perforated drainage conduits connecting the tubular elements of two successive intermediate elements and serving as collectors, before the placement of the filtering material.
- the invention finally relates to a tubular element useful for the implementation of the method of the invention and / or the production of a draining trench according to the invention, which comprises a perennial central tubular part made of a relatively resistant material (for example made of metal), closed tubular end portions which can be eliminated in a relatively fragile material (for example plastic), and a means for temporarily closing off said central part.
- said shutter means can be actuated from the ground surface.
- said closure means comprises an inflatable element, such as a balloon, which can be inflated and deflated from the surface of the ground.
- a valve can be used as a reversible closure means.
- the intermediate elements may have a cross section of any shape, for example square, rectangular or circular.
- the dimension of the intermediate elements, perpendicular to the trench may be equal to or greater than the thickness of the draining trench to be produced. A greater width can be advantageous, especially in soft ground, to minimize the risk of the intermediate element being bypassed by excavating fluid.
- the intermediate elements can be produced as a result of the hardening of the excavating fluid when the latter is hardenable, for example when a curable grout is used as the excavating fluid, or alternatively by the substitution of a curable material (for example a mortar or plastic concrete) to the excavating fluid when the latter is not hardenable.
- a curable material for example a mortar or plastic concrete
- a curable grout When used to produce the intermediate elements, it can be of any kind provided that it hardens into a hardened material of sufficient cohesion so that it plays its role of intermediate element.
- a grout can be used based on bentonite and cement. Once the grout has hardened, it can easily be cut by the excavation tool.
- Excavation fluids useful for excavating the elementary trenches between the intermediate elements must be non-hardening and non-clogging.
- Such fluids can be prepared from well known products commercially available from various suppliers. These include, for example REVERT ® manufactured by JOHNSON Company, distributed by JOHNSON FILTRATION SYSTEMS, ZI 86530 Availles. The rheology of these fluids is easily adjustable following the advice of the manufacturers. Non-clogging properties usually result from biodegradability of the fluid.
- the type of filter material placed in the elementary trenches constituting the draining trench is not critical. This material is usually formed of sand, gravel and gravel, the grain sizes and proportions of which are chosen according to the conditions prevailing on the site of the draining trench. Those skilled in the art will be able to determine an adequate material for each situation.
- Figures 1 to 6 are schematic sectional views illustrating the different stages of the method of the invention and the final draining trench obtained.
- FIG 7 is a schematic perspective view of a tubular member, implemented in the method of the invention.
- Figures 1 to 6 there is shown the different stages of making a draining slice by the method of the invention.
- a tubular element 2 illustrated in detail in FIG. 7, comprising a central metal part 3 in which a conduit 4, closed at its ends by lids 5, made of plastic, of length greater than that of part 3, but slightly less than the length of each of the excavations E.
- the element 2 also comprises a tube 6 perpendicular to the central part 3, connected to the latter and communicating with the interior of the conduit 4 by means of suitable bores provided on the central part and the conduit 4 and extending to above the ground surface.
- the element finally comprises an inflatable balloon 7 located inside the duct 4, in line with the tube 6, which can be inflated or deflated from the ground surface by means of a small pipe 8 running in the tube 6.
- the element 2 is oriented substantially parallel to the direction of the trench.
- Element 1 can rest on the bottom of the excavation receiving it, as shown, but this is not compulsory.
- the excavating fluid is then allowed to set in the excavations El-3 with the result of the formation of intermediate elements J1 to J3 molded in the ground and coating, at their lower end, the elements 2 ( Figure 2).
- the next step consists in excavating, under non-hardening excavating fluid, an elementary trench Tl between the intermediate elements Jl and J2 using an appropriate tool 9, such as an excavation bucket or equivalent, in causing the tool to pile up the sides of the intermediate elements Jl and J2 facing the trench Tl.
- the tool breaks in particular the ends of the plastic conduit 4 facing Tl, in particular eliminating the lids 5 (FIG. 3).
- the trench Tl is finished, it is filled with a suitable filter medium 10, while pumping the excavating fluid in order to remove it from Tl ( Figure 4).
- a first elementary panel Pi is thus obtained.
- the inflatable balloon 7 closes the tubular element in its central part.
- the balloon 7 can be inflated either before the positioning of the element 2 in the excavation, or after but in any case before the completion of the trench T2.
- the tubular element is closed during the construction of the trench T2, at least when the excavation tool arrives at the level of the element 2 because, otherwise, the filling excavation fluid T2 would pass through element 2 and would invade the trench Tl previously produced, which would go against the aim sought by the invention which is to have only one elementary trench filled with excavation fluid at a time.
- the excavation of the elemental trench T2 is carried out as that of the elemental trench Tl, with destruction of the sealed ends of the elements 2, then ⁇ pours the filter material in T2 while pumping the excavation fluid ( Figure 5). A second elementary panel P2 is thus obtained.
- Each tubular element 2 must finally be unobstructed to ensure that the various elementary panels constituting the draining trench communicate in service.
- the extraction of a particular balloon can be carried out at any time as soon as the two elementary trenches flanking the element 2 comprising said balloon have been emptied of their excavation fluid.
- the tubes 6, after extraction of the balloons can find utility as piezometers as well as for the maintenance of the passages made between the elementary panels. They can, in fact, be used to send a jet of water or pressurized air intended to rinse or unclog these passages.
- FIG. 6 an optional alternative embodiment has been illustrated including a step of positioning perforated conduits 11 acting as collectors between the elements 2. This optional step is carried out at the end of the excavation of each elementary trench, before spillage of filter material.
- the location of the openings of the tubular elements in the excavating fluid with a view to connecting the conduits 11 to it can be facilitated by an ultrasonic tracking device, known per se.
- the draining wall can have a thickness of 40-150 cm and a depth of 10 to 20 m and more.
- the intermediate elements can have a length of 1.5 to 2 m, and the elementary trenches can have a length of 4 to 12 m.
