Definitions

  • the object of the present invention is a constructive element for constructing consolidating structures such as containing, reinforcing, supporting, stabilizing and arranging works for the soils of hillsides, slopes and banks subject to sliding and/or eroding events.
  • the invention also refers to a production method for producing such a constructive element and to a consolidating structure incorporating a plurality of such prefabricated construction elements, as well as a method of installing them.
  • the invention is advantageously suitable for use in numerous landscape-engineering applications and especially for construction, reconditioning and maintenance works on infrastructures for roads and banks in a mountainous, forested, watery environment and the like.
  • Today's constructive elements generally comprise containing means constituted of a plurality of net-shaped, mutually interconnected panels.
  • the containing means obviously have a box-like, meaning parallelepiped form.
  • the mentioned constructive elements comprise a filling material suitable for filling the mentioned containing means.
  • This filling material must be made of pebbles or fractured rocks of an adequate shape and average size in the range of 20 to 30 cm. In the first case, this means pebbles encountered in the neighbourhood of the construction site of the consolidating structure, for instance from a river-bed. In the second case, it means fragments obtained reducing into pieces stones from rocks of an exclusively non-freezing type.
  • Such a constructive element finally avails itself of a reinforcing structure allowing it to be firmly connected to anchoring spikes driven into the soil.
  • a structure is, in detail, essentially constituted of a metal frame, and associated with the rear side of the mentioned containing means. The connection between the latter and the anchoring means normally occurs through removable blocking stops.
  • the main drawback encountered in the mentioned technical and constructive solution essentially consists in the long time delays needed for installing a consolidating structure made of the mentioned constructive elements. Specifically, these drawbacks are attributable to the operations needed for inserting and correctly emplacing the filling materials into the containing means, which are carried out manually by qualified personnel. In fact, this is the only way to provide the constructive element, and consequently the consolidating structure, with suitable characteristics of solidity and strength.
  • the aim of this invention is to set up a prefabricated constructive element to construct a soil consolidating structure, a method for producing said prefabricated constructive element and a consolidating structure obtainable by using a plurality of said constructive elements as well as a method for installing the latter, which is capable of resolving the drawbacks and problems encountered in the solutions of the prior art as described above.
  • an important object of the present invention is to set up a prefabricated constructive element especially suitable for use under emergency conditions, for instance for containing earth slides, floods and the like.
  • an important object of the present invention is to set up a prefabricated constructive element capable of granting an exceptional and durable structural strength to a consolidating structure.
  • a further object of the present invention is to set up a prefabricated constructive element capable of making the construction of a consolidating structure much more economical and safe.
  • An additional object of the present invention is to set up a prefabricated constructive element capable of granting the outer appearance of an already existing consolidating structure to a new consolidating structure.
  • the last object of the present invention is to set up a prefabricated constructive element capable of allowing a complete recovery of the consolidating structure in case of dismantling and re-utilizing it for new constructions.
  • the prefabricated constructive element comprises, based on the prior art, containing means and filling material for filling said containing means.
  • the aforesaid filling material presents above all the peculiar feature of comprising at least a supporting core capable of supporting the consolidating structure.
  • This peculiar feature allows achieving the aim of the invention, as will also be appreciated later, because it allows setting up a consolidating structure in much shorter time and through the prevalent usage of installation equipments.
  • This solution in fact allows transferring the constructive elements, by conventional means of transport, from the production site to the usage site and to install it in a likewise facilitated manner and with the practically exclusive usage of terrestrial or aerial means. In conclusion, it happens to be possible to take timely and rapid steps to face even the worst emergencies. Moreover, this solution also allows setting up suitable stocks of constructive elements for use in emergencies.
  • This peculiar feature also allows attaining another object of the invention, as will also be appreciated from the description to follow, because it is capable of granting an exceptional and lasting structural strength to a consolidating structure.
  • This solution in fact allows the constructive element to achieve a considerable and permanent strength against accidental impacts of an even serious nature on the part of rocks or tree trunks and the erosive action caused for instance by water streams. Moreover, this solution allows a constructive element to attain a considerable crushing strength, to make it possible to advantageously create larger consolidating structures than conventional ones.
  • said filling material also presents the peculiar feature of comprising at least one shielding cover associated with said supporting core, which functions to shield the latter.
  • This peculiarity allows achieving another object of the present invention because, as will be appreciated from the description to follow, it allows granting to a new consolidating structure the outer appearance of an already existing consolidating structure.
  • This solution therefore allows rendering environmental recovery jobs, although performed at different and even far removed periods of time, uniform from a visual viewpoint.
  • This aspect appears to have a particular advantage in undertakings aimed at reconditioning certain consolidating structures of the past, which are composed of traditional constructive elements capable of being replaced by the prefabricated constructive elements according to this invention.
  • the constructive element according to the invention also appears advantageous because it allows a full recovery where a consolidating structure is dismantled and eventually re-utilized for new construction jobs. On the contrary, the constructive elements according to the art become useless, because they loosen to the point of releasing the relative filling material.
  • a further advantageous aspect of the invention is in the fact that the work of the operators needed to apply blocking stops is only needed after concluding the installation of the consolidating structure, meaning under conditions of adequate safety.
  • such interventions must be carried out in the initial phase, thus exposing the operators to serious impending risks, for instance in cases of slides with breakaway masses of earth, rocks and the like.
  • the constructive element in fact occupies the same volume as that of conventional constructive elements, and its overall weight is suitable for transport by the same trucks used in the construction trade.
  • this prefabricated constructive element 19 comprises above all containing means, indicated as a whole by the reference number 20, which are appropriately constituted of a plurality of net-like, reciprocally interconnected panels.
  • the latter are advantageously made of robust metallic nets made of polygonal double-twisted meshes to enhance their strength and subjected to a surface galvanizing treatment to extend their durability.
  • this prefabricated constructive element 19 comprises a filling material, indicated in the overall by the reference number 22, which is suitable for filling the mentioned containing means 20.
  • this filling material 22 comprises above all a supporting core, indicated by the reference number 23, which fulfills the function of supporting the consolidating structure shown in Figure 1 , as detailed below.
  • Said filling material 22 also comprises a shielding cover, indicated by the reference number 24, which is associated with the supporting core 23 mentioned above and has the function of shielding the latter.
  • the mentioned supporting core 23 is constituted of a concrete matrix 25 and a reinforcing/lifting frame 26, respectively, which is incorporated, as a whole, in the concrete matrix 25.
  • the mentioned reinforcing/lifting frame 26 consists in turn of a cage of bars 27 and a triplet of reticular panels 28, arranged in a frontal position and on the sides of said cage of bars 27, respectively.
  • the mentioned supporting core 23 is arranged in the central and rearward area of the mentioned containing means 20.
  • the solution of employing the mentioned triplet of reticular panels 28 determines a considerably advantageous appearance. These reticular panels 28 allow it on one hand to insert appropriate stiffening ties designed to stiffen the containing means 20, as will be seen in detail further on, and on the other hand to confer the entire supporting core 23 greater strength, because said reticular panels 28 are all incorporated into the concrete matrix 25.
  • the mentioned shielding cover 24 is essentially formed by a front layer 29, lateral layers 30 and a final covering layer 31.
  • These layers 29, 30 and 31 are constituted of a plurality of rock fragments 32 obtained from a non-freezing rock. These rock fragments 32 are advantageously partly incorporated in the concrete matrix 25 mentioned above.
  • This technical measure determines a further advantageous appearance of the invention. In case of a rupture of the containing means 20, the release of the outermost rock fragments 32 does not in fact compromise the outer appearance of the prefabricated constructive element 19, because the supporting core 23 retains those rock fragments 32 that are at least partially incorporated into the concrete matrix 25 mentioned above.
  • this prefabricated constructive element 19 is fitted with an inserting passage 33 transversally carved out of the mentioned supporting core 23, so as to allow inserting an anchoring spike 212.
  • This prefabricated constructive element 19 is completed by using an access opening 34 carved out from the portion facing the mentioned shielding cover 24 at the outlet level of the mentioned inserting passage 33, to allow the access of the mentioned anchoring spike 212.
  • the prefabricated constructive element 19 comprises a plurality of stiffening ties 35. The latter are interposed between the mentioned reticular panels 28 and the mentioned containing means 20 through the mentioned rock fragments 32. These stiffening ties 35 are entrusted with the task of stiffening the mentioned containing means 20.
  • the production method for producing the prefabricated constructive element 19 is described as follows.
  • the preliminary phase of this method consists in assembling suitable conforming means, indicated as a whole by the reference number 101, to form the mentioned constructive element 19.
  • this phase is carried out on a supporting floor and consists in a sequence of an operation to flatwise approach a pair of "L"-shaped and laid down walls 102, and an operation to tie up the extremities in contact with this pair of walls 102.
  • the method then provides for inserting said containing means 20, in a vertical sense from the top and in a partially assembled form, into the mentioned conforming means 101. This allows achieving the operating condition illustrated in the following Figure 8 .
  • the next phase then comprises a vertical topside insertion of a delimiting and supporting armature 103 without a floor, in a position set up at the center and moved backward from the mentioned containing means 20.
  • the purpose of this delimiting and supporting armature 103 is to define a positioning sector indicated by 104 in the subsequent Figure 9 , to facilitate the emplacement of the mentioned rock fragments 32 and to support the relative installation.
  • the method provides for positioning the triplet of reticular panels 28 at the sides of the mentioned delimiting and supporting armature 103.
  • an operator not evidenced here
  • steps inside the delimiting and supporting armature 103 are examples of the delimiting and supporting armature 103.
  • the operator proceeds with picking up a rock fragment 32 from a heap set up in the immediate neighborhood of the conforming means 101 and appropriately arranging it inside the positioning sector 104. In so doing, the operator produces a first layer of these rock fragments 32. The same operator then manually proceeds to apply a number of stiffening ties 35, so-called ties interposed between the mentioned reticular panels 28 and the mentioned containing means 20, just above the mentioned first layer of rock fragments 32. After completing this operation, the operator proceeds to lay down a plurality of subsequent layers of said rock fragments 32 inside the mentioned positioning sector 104, until reaching the summit of the mentioned containing means 20, and to apply a plurality of stiffening ties 35 interposed between the mentioned subsequent layers.
  • the same operator then appropriately provides for inserting a profiling body 105 into the positioning sector set up in the front of and approximately at the center of the area between the mentioned rock fragments 32, as detailed in Figure 11 .
  • the production of the shielding 24 can be considered to be complete, and the operator thus quits the delimiting and supporting armature 103.
  • the mentioned cage of bars 27 is then vertically inserted from above and rested inside the mentioned delimiting and supporting armature 103.
  • said operator takes care of fastening a conforming body 106, in this case a tubular body, into the mentioned cage of bars 27.
  • This conforming body 106 is disposed in a position facing the mentioned profiling body 105, in a transversal and downward sloping condition.
  • this conforming body 106 is to confer a shape to the mentioned inserting passage 33.
  • the method provides for injecting a concrete in a pasty condition 107 into the mentioned delimiting and supporting armature 103, and at the same time for extracting this delimiting and supporting structure 103 from its inserting position. It should be clarified that said extraction allows the concrete 107 to spread out inside these conforming means 101, until it reaches and incorporates at first the triplet of reticular panels 28 and then the rock fragments 32 that are in contact with these reticular panels 28. It is precisely for this reason that the speed of extraction of said delimiting and supporting armature 103 must be functional to the speed of diffusion of the concrete 107.
  • the concrete 107 is advantageously, over the duration and at the conclusion of the input phase, subjected to some suitable vibration to promote the mentioned diffusion and achievement of a suitable degree of self-leveling.
  • the general situation will look as shown in Figure 16 , in which the conformation of the supporting core 23 is completed and the delimiting and supporting armature 103 is set in a raised position with respect to the conforming means 101 and ready to be removed.
  • the operator proceeds with drowning a plurality of rock fragments 32 in the surface of the concrete 108, and immediately thereafter with closing the upper portion of the mentioned containing means 20.
  • the method provides, at this stage, for holding the prefabricated constructive element 19 in a stationary position inside the conforming means 101, for a suitable length of time to cause the concrete 107 to attain the most suitable degree of curing.
  • the prefabricated construction element 19 is delivered from the conforming means 101. In detail, the delivery occurs simply by releasing and then removing the "L"-shaped and laid-down walls 102.
  • the prefabricated constructive element 19 is then hooked up to the portions of the reinforcing/lifting frame 26 which are projecting from the supporting core 23, and transferred to storage.
  • this consolidating structure 210 is essentially composed of a plurality of superimposed, offset and interconnected rows 211 of prefabricated constructive elements 19, all having the features mentioned above.
  • the consolidating structure 210 also comprises anchoring spikes 212 suitably driven into the ground that perform the function of anchoring the mentioned rows 211 to the ground.
  • this consolidating structure 210 includes blocking stops 213 interposed between the mentioned anchoring spikes 212 and the prefabricated constructive elements 19. The blocking stops 213 have the purpose of blocking said prefabricated constructive elements 19 to the respective anchoring spikes 212.
  • the method of installing said consolidating structure 210 is in turn articulated into the following operating phases. It is at first necessary to appropriately arrange the bottom 214 on the ground, based on the characteristics of the consolidating structure 210. After completing this phase, one takes up the operation of positioning a first row 211 of prefabricated constructive elements 19 by using installation equipment on the mentioned bottom 214, and of the relative filling with a draining gravel material from the rear. This operation is followed by another essentially similar operation, which consists of positioning a second row 211 of prefabricated constructive elements 19, by installation equipment, to be set up in a superimposed and offset position with respect to that of the first row 211.
  • the following phase than provides for driving a plurality of said anchoring spikes 212 into the ground, while using specific installation equipment.
  • the mentioned anchoring spikes 212 are appropriately inserted at a distance from the mentioned bottom 214 that is functional with respect to the overall height of this consolidating structure 210 and at an angle with respect to the horizontal that is suitable to perform the anchoring to the mentioned consolidating structure 210. Simultaneously with this driving-in operation, a cement slurry is injection-pumped into these anchoring spikes 212. A superimposed row 211 of prefabricated constructive elements 19 is again emplaced, by installation equipment, in a position superimposed and offset with respect to each underlying row 211. This operation is repeated until the last superimposed row 211 reaches the height demanded by the consolidating structure 210.
  • a team of operators proceeds to apply the stiffening ties (not shown here) interposed between the mentioned prefabricated constructive elements 19, for stiffening the consolidating structure 210 as a whole.
  • the same team of operators applies the blocking stops 213 on the lengths of the anchoring spikes 212 that project from the prefabricated constructive elements 19.
  • the volume behind the last row of the consolidating structure 210 is then filled with debris and small-size pebbles, and the overlaying zone of said bottom is finished at the end.
  • the prefabricated constructive element the relative method of production
  • the consolidating structure thus obtainable by using a plurality of said prefabricated constructive elements and the method of installing the same achieve the expected aim and objects.
  • a further beneficial aspect is in the fact that the consolidating structure allows a suitable drainage of the surface waters from the bottom, as it permits its evacuation through the lateral layers of the shielding cover. It is finally mentioned that this production method is advantageously performed wholly in the factory, and therefore under optimum operating conditions, especially as refers to the safety of the operators.
  • the prefabricated constructive element, the relative method of production, the consolidating structure obtainable by using a plurality of said prefabricated constructive elements and the method of installing the latter according to the invention are susceptible to numerous modifications and variants, all of which fall into the range of the same inventive concept.
