    专利说明:

    [0001] The present invention relates to civil engineering works of the reinforced soil type, for example an embankment, a dike, a gravity dam, a retaining mass, a retention pond-embankment fluids, a bridge abutment, etc .... This type of work usually includes a siding and embankment in which are installed reinforcement reinforcement connected to the facing.
    [0002] The present invention relates in particular to facing elements, often in the form of prefabricated concrete blocks, their constitution and the method of obtaining such facing blocks. More specifically, one is interested in the attachment zones 15 embankment reinforcement inside the facing block. Various solutions and configurations are known from the prior art for attaching to the facing a continuous reinforcing reinforcement with a forward strand, a loop which passes around an anchoring core in the facing block, and a return strand. There may be mentioned documents US5839855 and US8790045. According to the known art, a plastic molding insert is placed in a mold for the manufacture of a facing block, and concrete is poured in liquid form into the volume intended for the facing block, part of the concrete to occupy a space corresponding to the anchor core provided to retain the embankment reinforcement, but without occupying a cavity reserved for the passage of the embankment reinforcement.
    [0003] In addition, in some cases, this molding insert plays a sealing role, and prevents liquid concrete from entering the cavity that will be traversed by the reinforcing reinforcement once it is installed. Contact between the concrete and the reinforcement could cause premature degradation thereof. In some other cases, this molding insert also plays a sealing role in the completed work. The inventors have noticed on the one hand that the manufacture of such molding inserts presented certain difficulties and proved to require complex molds.
    [0004] On the other hand, the inventors have noticed that these known molding inserts, which must be transported from their own manufacturing site to the prefabrication site of the facing blocks, occupy a large volume with respect to their volume of material (otherwise says the empty rate is important in the packages). There is therefore a need to further optimize the molding inserts, their manufacture, their installation in the prefabrication mold blocks, while retaining good mechanical strength properties required for the connection / bond between the facing blocks and the reinforcements reinforcement in the embankment and therefore for the good consistency of the work to erect. For this purpose, according to the invention, there is provided a molding insert, configured to be inserted into a mold for manufacturing a concrete facing block intended for a structure in reinforced soil, said reinforced soil structure comprising a facing formed by such cladding blocks and a backfill in which are installed reinforcements, preferably in the form of strips, connected to the facing, the molding insert comprising: - a shell, defining a general volume of a connection binding a reinforcement at the facing block, said general volume opening by flaring towards a reference plane P, - a core casing, obtained by molding 30 distinctly from the shell, the shell having a first lateral face pierced with a first orifice in which is fitted a first end portion of the core casing, characterized in that the core casing has a generally frustoconical shape. Thanks to these arrangements, before assembly, several core envelopes can be stacked one inside the other, and several shells can be stacked one inside the other, which considerably reduces the rate of vacuum in the transport packages of these parts, which makes the overall solution less expensive. In addition, such a core shell can be easily assembled into such a shell to form a molding insert for creating a cavity subsequently used as a connection to a frame.
    [0005] In various embodiments of the invention, one or more of the following arrangements may be used: the shell has a second lateral face pierced with a second orifice in which is nested a second end portion of the core shell; advantageously, during assembly, it is possible to obtain a simultaneous jamming of the core casing respectively in the two lateral faces of the shell; the interlocking is done without substantial clearance, benefiting from a corner effect of the frustoconical shape of the core envelope, this at the level of the first end portion and the second end portion; a sufficiently closed interface is thus obtained between the two parts to prevent the casting concrete from entering the cavity intended to receive a reinforcement; the taper al of the envelope of the core is between 1 degree and 10 degrees; the difference in size between the narrow side and the wider side of the truncated cone shape remains small, the strength of the nucleus to obtain is therefore little dissymmetrical; furthermore before effective use several core envelopes can be stacked forming a compact stack and their transport is easy; the second orifice is larger than the first orifice; advantageously, during assembly, it is possible to thread the core casing easily through the second orifice with a comfortable clearance, the first orifice has a shape corresponding to the shape of the first end portion and the second orifice to orifice has a shape corresponding to the shape of the second end portion; a closed continuous interface is thus obtained both on the periphery of the first orifice and on the periphery of the second orifice. in addition, the shape of the second end can be obtained by homothety from the first end; So that the core shell forms an exact cone frustum, without singularity of shape, which provides satisfactory strength to the anchoring core obtained later; preferably the two orifices have similar shapes and the ratio of their size corresponds to the ratio of the sections of the first and second end portions; whereby a homogeneous jamming is achieved which occurs at the same time at the first orifice and the second orifice, thus obtaining a basic 'natural' seal between the core shell and the shell; - The shell is obtained by molding in one piece; which is made possible by the flared shape of the hull; alternatively, the shell can be obtained in two parts, that is to say with a body and a lid; The shell and the core casing are molded from an injectable thermoplastic material, of polyethylene, polyolefin or polypropylene type; thus advantageously used a cheap material and easy implementation; The shell and the core shell have sufficient flexibility to deform at the interface between the core shell and the holes in the shell, preferably with a wall thickness of between 0.5mm and 2 mm; this flexibility makes it possible to form a continuous docking seal all around the orifices, which makes it possible to obtain a satisfactory seal for most of the usual configurations; a specific weld joint can be formed at the interface between the core shell and the shell; which makes it possible to obtain a high degree of sealing for the molding insert 5 and thus for the final work; - The shell can dock on a rear sealing membrane of the block, by means of a border arranged in the reference plane P; it is thus possible to achieve a complete seal on the entire rear face of the facing block, including the attachment zone of the armature; the reference section of the conical core envelope is an ovoid shape; this turns out to be an optimized form in terms of the tensile strength exerted by the reinforcement and for easy threading of the reinforcement and protection of the reinforcement; the respective centers of the first and second orifices have positions offset in distance with respect to the reference plane P, so that the axis of the casing of the core W has an inclination a2 with respect to the reference plane.
    [0006] So that a length of travel of the same armature is obtained over the width of the armature, and that one avoids creating a voltage imbalance between one side and the other of the band of the armature. frame; Furthermore, the invention also relates to a method for producing a molding insert: providing a shell, intended to delimit a general volume of the connection binding an armature to the facing block, said general volume opening by flaring out to a reference plane P, 30 - provide a core casing, obtained by molding distinctly from the shell, the core casing having a generally frustoconical shape, - assembling the core casing in the shell.
    [0007] Other aspects, objects and advantages of the invention will appear on reading the following description of several of its embodiments, given by way of non-limiting examples. The invention will also be better understood with reference to the accompanying drawings, in which: FIG. 1 is a diagrammatic sectional view of a civil engineering work in which the invention is practiced; - Figure 2 shows a detailed sectional view of the connection of a frame at the back of the facing; FIG. 3 is an exploded perspective diagram of the molding insert used according to the invention; - Figure 4 is a detailed sectional view of the connection of a frame at the back of the facing, along the section line IV in Figure 2 and 5; FIG. 5 is a detailed sectional view of the connection of a reinforcement at the rear of the facing, along the section line V in FIG. 4; - Figure 6 is a view similar to Figure 4 according to an alternative embodiment; FIG. 7 shows several core envelopes 20 stacked one inside the other; - Figure 8 shows several shells stacked in each other; - Figure 9 is a view similar to Figure 4 according to an alternative embodiment; FIG. 10 is a view similar to FIG. 4 according to another embodiment; FIG. 11A illustrates the molding operation of the prefabricated facing block with the molding inserts in the upper position; Fig. 11B is analogous to Fig. 10 with the molding inserts in the lower position and a sealing membrane; FIG. 12 is an exploded perspective view of the molding insert used according to the invention; In the various figures, the same references 3025815 7 designate identical or similar elements. By way of example, a civil engineering structure according to the invention may be a dam, a dike, a fluid retention structure, a channel bank, a construction intended to widen or enhance an existing structure, a delimited slope. by a siding, a bridge abutment or more generally any other civil engineering work. FIG. 1 represents a civil engineering work 90 10 according to the invention, comprising: a cladding 9 extending from a foundation which, in the example represented is the floor 91, a backfill 7 of a structure located at the rear of the facing, - reinforcements 3 which extend inside the embankment and which are connected to the facing, more precisely in anchoring zones 5 formed at the rear of the facing. The reinforcements 3 play a role of mechanical stabilization of the embankment 92 and ensure the structural cohesion between the embankment 92 and the facing 9, as known per se. The facing 9 is substantially vertical as illustrated in Figure 1 (in the direction marked 'Z'), and 25 comprises a front surface 95 substantially coincides with the outer face of the work and a rear surface 96 located opposite of the front surface 95 and adjacent to the backfill 7. In a Cartesian coordinate system, the facing generally extends in a plane YZ with a normal along the X axis which is perpendicular to the plane. In addition, a reference plane P is defined at the rear surface 96 of the facing. In the example shown, the facing 9 is a concrete wall, the wall being preferably made in a modular manner, as illustrated in FIG. 1, that is to say by the superposition of plates in prefabricated concrete 4 ('cladding blocks' 4) which are assembled on the site of the structure during its construction. Because of their weight and size, the cladding blocks 5 are preferably manufactured in the immediate vicinity of the construction site of the structure. It should be noted that the facing 9 can be inclined and that the front face can be vegetated. The space opposite the front face may be in the open air or filled with a liquid to be retained. The embankment 7 of the structure may be with earth and / or stony aggregates, these materials being roll compacted by strata. Backfill 7 contributes by its weight to the stability of the civil engineering work 90 in question. The embankment 7 is made by installing successive layers from the ground or foundation 91 to the upper end of the structure. Between each layer, a plurality of reinforcement armatures 3 are disposed substantially in a horizontal plane over the entire surface. It is possible to arrange the armatures 3 at a distance from each other along Y and parallel to one another, in this case they extend from the rear of the facing 25 substantially in the direction X. According to another configuration, the armatures 3 can extend obliquely with respect to the X direction (see further and Fig 4 and 6). Thanks to the inclusion of reinforcements 3 in the embankment 7, so is formed what is called a "reinforced soil".
    [0008] The reinforcements 3 are made in the form of reinforcement strips made of synthetic fabric or plastics material. Also referred to as "geotextile web", a known example is given in EP2247797. Each reinforcing strip typically has a generally rectangular section with a width of 3 to 10 cm, typically 5 cm, and a thickness of between 2 and 6 mm, typically 4 mm; moreover, the armature extends over a relatively long length in its so-called longitudinal direction X ', namely several meters or even several tens of meters. The armature works essentially in traction along its longitudinal direction, for which it has a good resistance. The armature can bend in the direction perpendicular to its plane, so as to form a loop around the anchor core. Twisting around the longitudinal axis is also possible.
    [0009] In certain configurations, the armature 3 is installed in a given horizontal plane forming zigzags, that is, it enters and leaves in the facing block at the attachment zone according to X ' with a certain angle vis-à-vis the normal direction X.
    [0010] The interface and attachment between the reinforcements 3 and the cladding 9 is described below in detail with reference to FIGS. 2-5. Indeed, each of the plates 4 of the facing comprises at least one attachment zone 5 for receiving and anchoring a reinforcement 3. This attachment zone 5 comprises a cavity 50 forming a recess inside said plate 4, and opening onto the rear surface 96 of the facing 9. Preferably, the cavity 50 opens only on the rear surface 96. The cavity is traversed by an anchoring core 6 17 along the Y axis, anchoring core around which the armature 3 passes and is retained. The anchoring core 6 delimits and separates an upper mouth 51 and a lower mouth 52 from the cavity 50. An armature 3 is installed by threading one end of the reinforcement through one of the mouths, for example the lower mouth. The reinforcement is then pushed so that it turns into the bottom 53 of the cavity and exits at the upper mouth. Thus, the armature loops around the core with a forward strand 31, a loop portion 33 retained by the anchor core and a return strand 32. It will be noted that the facing blocks have a general thickness (according to X) noted Dl (typically in the range [10cm-50cm]) and that the depth of the cavity from the back of the facing is marked D2, D2 can typically be between 1/5 and 3/5 of Dl. Pouring blocks are produced by pouring liquid concrete into a prefabrication mold 47, and then the concrete is expected to take off to unmould and move the facing block to the worksite and install it on the siding under construction in the work. . FIG. 11A illustrates the step of prefabrication of the cladding blocks.
    [0011] A mold 47 of generally parallelepipedal shape is provided in the illustrated example, one or more molding inserts 8 are placed inside the molding form by means of which the above-mentioned attachment zones 5 are formed.
    [0012] As illustrated in FIGS. 3,4,5, the molding insert 8 consists of a shell 1 and a core shell 2. Each of these parts (core shell and shell) is obtained by molding, independently each other, most often on a site remote from the site where they will be assembled for implementation. Then, on the prefabrication site of the facing blocks, a core envelope is assembled in a shell to form a molding insert 8 which is placed in the mold 47. The shell 1 delimits a general volume of the connection 30 an armature 3 to the facing block, said general volume opening flaring towards the reference plane P, in other words this volume forms a flared bowl open towards the mouth 51.52 to the outside. The core casing is intended to delimit the volume of the aforementioned concrete anchor core 6.
    [0013] It will be noted that the core casing 2 advantageously has a general shape of a truncated cone centered on the axis denoted W, a conicity whose utility will be seen hereinafter. The generating base of this frustoconical shape 5 is in the illustrated example an ellipse, but of course any other shape could be suitable. Generally, the core shell 2 is a simple thin-walled tubular shape with a vacuum inside and both ends open. However, by virtue of the general shape of the truncated cone, it is noted that the first end portion 21 of the core casing has dimensions a little smaller than those of the second end portion 22. The shell 1 comprises a first lateral face 15 pierced with a first orifice 11, a second lateral face 16 pierced with a second orifice 12, and two other so-called longitudinal faces 13, 14 which meet continuously in the bottom zone 83 of the shell (bottom zone 83 intended to form the bottom of the cavity).
    [0014] It will be noted that the lateral faces 15, 16 are not parallel, the bottom is narrower and an opening angle (respectively marked 01 and 02) is provided which gives a general flaring of the hull in the direction of the main opening. which is intended to be arranged in the vicinity of the abovementioned reference plane P. Similarly, the longitudinal faces 13,14 diverge outwards (with an angle noted pl, cf Fig. 5) and contribute to the general flaring of the shell. Advantageously, thanks to such a flared shape, several shells 1 can be stacked one inside the other as is illustrated in FIG. 8. Such an assembly lE proves to be very compact, the distance difference between two adjacent stacked shells can be be less than one quarter of the depth D2 of the hull.
    [0015] Note that the core envelopes 2, too, can be stacked one inside the other as this 3025815 12 is illustrated in Figure 7. Such an assembly 2E is very compact, the distance difference between two envelopes stacked adjacent may be less than a quarter of the axial length L2 of the core shell (see Fig. 3).
    [0016] Thus, it is possible to carry many hulls in a small volume and to carry a lot of core envelopes in a reduced volume from production sites which can be separate and which are also very far away from the construction site. book 90.
    [0017] At the time of assembly of the molding insert 8, the core casing 2 is threaded with its smallest end portion in front of the movement (as shown in FIG. 3) through the second aperture 12 of the shell through the first opening 11 of the shell 1. As a result, the first end portion 21 is nested in the first opening 11 of the core shell, and the second portion end 22 is nested in the second opening 12 of the core casing. The interlocking is preferably without play so that the interface between the first end portion and the first orifice 11 forms a continuous closed seal; for this purpose, it is possible to provide a certain flexibility of the material 25 which contributes to catching up with a possible manufacturing dispersion. Similarly, at the second orifice 12, the interlocking is preferably without play. Advantageously, to obtain a good interlocking, in other words a good jamming of the core casing 2 in the orifices 11, 12 of the shell, a taper al is provided between 1 ° and 10 °, preferably close to 5 °. In the illustrated example, the core shell 2 forms an exact conical frustum, i.e., the first elliptical end portion 35 is homothetic with the second end portion.
    [0018] Moreover, it is expected that the ratio of the size of the first and second ports (11,12) corresponds to the ratio of the sections of the first and second end portions (21,22), which guarantees a simultaneous placement at the level 5 both holes during the insertion movement. In order to prevent the core envelope from projecting too far from the lateral faces 15, 16 of the shell, it is also anticipated that the axial ends of the core shell are truncated by each following a cut-off section along the planes P1 'and P2 ', neighbors and outwardly offset with respect to planes P1 and P2 in which respectively extend the first side face 15 and the second side face 16. In Figure 4, the axis W is parallel to the reference plane P, that is to say that the point Wl where the plane Pl and the axis W intersect and the point W2 where the plane P2 intersect the axis W are at the same distance from the reference plane P On the other hand, in FIG. 6, the axis W is not parallel to the reference plane P, it deviates from the angle α2. More precisely, the point W1 'where the plane Pl and the axis W intersect is further from the reference plane than the point W2 where the plane P2 intersects with the axis W. Advantageously according to this arrangement, when the angle a2 25 is close to al, or preferably slightly greater than al, the reinforcing strip 3 makes a 'flat' loop on the rear of the anchoring core 6 and consequently each side of the strip travels the same distance in the attachment zone 5 inside the cladding. This avoids creating an imbalance which could increase the stresses on one side of the reinforcing strip 3. When pouring liquid concrete 45 into the prefabrication mold 47, which is vibrated with vibrators 48 , the concrete 45 enters the empty space in the middle of the core casing 2 to form the anchoring core 6 and more concrete comes to marry the lateral faces 15,16 and the longitudinal faces 13,14 of the hull, without however entering the cavity 50 provided for the passage and the anchoring of the frame. It is not excluded furthermore to insert a metal reinforcement (not shown) in the core along the axis W. In addition, a stop flange 24 may be provided on the second end (so the larger) of the core shell 2 as shown in Fig. 6. This flange limits the stroke of the core shell during the insertion movement. Furthermore, it can be provided notches (not shown) which serve as clipping, and which provide a sensory feedback for the operator who proceeds to the insertion of the core casing in the shell Advantageously, Alignment marks may be provided on the shell 1R and on the shell 2R, which allow the operator to correctly orient the core shell around its axis W during the insertion operation ( cf Fig 12). In addition, there is provided on the shell 1 a minimum filler mark 49 of the mold corresponding to a level marked PRO in FIG. 4, a minimum level which guarantees sufficient anchorage tensile strength. Of course, the molding insert 8 is embedded in the concrete is integral part of the cladding block 4 completed ready for use on the facing. In Figure 9, there is illustrated a variant where the siding 9 must have a good seal to liquids during the life of the structure. Therefore, not only should the molding insert 8 hinder penetration of the liquid concrete during the molding phase, but it must also be liquid-tight during the service life of the work. For this purpose, in addition to the fitted fitting advantage already presented above, it is provided to add a heat seal 18 over the entire periphery of the interface of the core shell to the shell; it is noted that the access to achieve this heat sealing from the outside is easy after insertion of the core shell into position in the shell. In addition, there is provided at the rear of the facing block a sealing membrane 19 which can be made of plastic for example high density polyethylene (HDPE) or another thermoplastic polymer. This sealing membrane 19 (or "sealing plate") is adjacent to the rear surface 96 of the concrete facing itself. This sealing membrane 19 is welded to the edge 10 of the shell by a thermo-welded bead 17.
    [0019] It will be noted that the seal 17 between the waterproofing membrane 19 and the edge 10 of the shell may be made by gluing or heat sealing or any other means known in the art. The waterproofing membrane 19 is preferably already installed on the facing block before being installed on the structure. In fact, as illustrated in FIG. 11B, after cutting of a sealing membrane to the size of the facing block, rectangular openings are provided at the locations of the attachment zones 5. molding 8 above and are fixed (by gluing or heat sealing) at the place of the openings in the waterproofing membrane. Then the sealing plate 19 with mold inserts 30 is placed in the bottom of the mold (FIG. 11B), and the liquid concrete 45 is poured. The method for assembling the civil engineering structure 90 according to the invention is not described in detail here because known per se. Strata is applied by installing the backfill material to a level where attachment areas are provided; then cup with a compactor; then we install the frames; then we begin again for the next layer and so on to the top of the work.
    [0020] With regard to the facing, it can also be erected in layers at the same time as the backfill and the reinforcements, or it can be erected beforehand in advance of phase. With regard to the sealing arrangements of the entire cladding in service, the operations for making the sealing connections at the interface of the facing cladding blocks are described in EP2567032 (case 564). . As regards the materials, the shell and the core casing 2 are molded from an injectable thermoplastic material, of the polyethylene, polyolefin, polypropylene or other equivalent material type. The wall thickness will typically be between 0.5mm and 2mm. Note that the wall thickness and robustness of these parts will be calculated to meet their assembly 20 and up to the concrete casting operation included, because once poured concrete, it is the concrete that gives the rigidity to all, and the shell and the core casing have only a role of contact protection vis-à-vis the frame 3. It is not excluded to provide small ribs of Reinforcement for optimizing the overall thickness of the shell 1 and the core shell 2. In Fig. 10, a variant is shown in which the shell is formed in two parts, namely a body 28 which comprises the first orifice and a cover 29 which includes the second port. For example, it is possible to insert the core envelope into the body 28 and then to introduce over the cover 29 which interfaces both the body and the core envelope from the inside as shown in FIG. The lid and the body could be hinged at a hinge area and provided for the lid to close towards the final illustrated position. Thus the shell would be obtained by a single molding operation.
    [0021] In Figure 12, are shown on the one hand the joint plane PJ demolding the shell and on the other hand an ovoid shape for the anchor core. This particularly optimized ovoid shape is described in detail in U58790045; it is noted that the rear half is very close to a hemi-cylindrical shape which favors a homogeneous radius of curvature for the reinforcement in its loop 33 around the core, the front half is more elliptical, which makes it possible to have the very open upper and lower mouths to favor all armature entry and exit configurations.
