Description
The present invention relates to a method for forming a cellular structure for containing loose material to stabilize and reinforce soils.
As it is known, cellular structures for containing 5 loose materials to stabilize and reinforce soils, commonly termed "geocells", are formed by means of nets that are mutually joined so as to form closed spaces in which loose materials, such as gravel and the like, are introduced.
For example, patent GB 2,078,833 discloses a structure 10 in which the joint is provided by means of a system known in the art as "bodkin". This type of joint has considerable drawbacks in terms of application, since, in order to provide it, one has to fold along the joining line one of the two nets to be joined and insert the portion of the 15 folded net in the loops of the second net, causing it to exit from the other side and making an iron rod pass in the space that is thus formed, for providing connection between the two nets.
This type of joint is scarcely practical and scarcely 20 versatile, since it becomes difficult to use in on-site applications if it is necessary to join materials difficult to fold, such as for example metal materials.
Other known methods, such as for example the one disclosed in patent US 4,394,924, provide for the forming 25 of cells constituted by cube-liXe or parallelepipedal gabions in which considerable problems are encountered in providing the joints at the closing edges, which are obtained by interweaving metal wires.
3 ~ ~ ~
A principal aim of the invention is to solve the above described problems by providing a method for forming a cellular structure for containing loose material to stabilize and reinforce soils, in which it is possible to 5 quickly join the nets without having to mutually interpenetrate them, but simply by using elements that require the mutually adjacent arrangement of the nets.
A particular object of the invention is to provide a cellular structure that can be obtained with nets of any 10 type and particularly with plastic nets having single or double orientation or no orientation at all, or metal nets having an appropriate pattern, such as preferably a pattern with a substantially square or rectangular mesh.
Another object of the present invention is to provide : ~.
15 a method that allows to obtain a very wide range of cell shape types according to the particular kind of application.
A further object of the present invention is to provide a method that allows to couple multiple mutually 20 superimposed nets, thus obtaining a considerable variety of structural shapes for the geocells.
With this aim, the objects mentioned and others which will become apparent hereinafter in view, there is provided, according to the invention, a method for forming 25 a cellular structure for containing loose material to stabilize and reinforce soils, which i5 characterized in that it consists in arranging side by side at least one portion of at least two nets; in arranging a joining element where the nets are adjacent, lnserting it from the h~ 6 e~ 7 7 ~ outer face of one of said nets and making it exit from the outer face of the furthest adjacent net; in connecting at least one locking element, which can engage said outer faces and said joining element, to the portions of said 5 joining element that exit from said outer faces; and in mutually connecting said nets in multiple spaced points to form multiple cells that are peripherally delimited by said nets.
Further characteristics and advantages of the method 10 for forming a cellular structure will become apparent from the following detailed description of some preferred but not exclusive embodiments thereof, illustrated only by way of non-limitative example in the accompanying drawings, wherein:

:: , With reference to the above figures, the method for 20 forming a cellular structure for containing loose material :
to stabilize and reinforce soils, according to the invention, consists in arranging side by side two or more nets, respectively designated by the reference numerals 1, 2 and 3, in the case of the mutually adjacent arrangement 25 of three nets, in at least one region, preferably arranging the nets so that the meshes are distributed in a matching arrangement.
The overlap can be provided by fully superimposing the two nets or simply by superimposing them in some preset ~2~7 regions.
Once the overlap has been performed, a joining element, which can be variously formed, is applied in the selected joining regions.
As shown in figure 4, it is possible to provide a joining element which is constituted by a spiral 10 or, optionally, as illustrated in figure 5, by a joining ..
element 20 with rings 21 that are joined by a vertical bar 22.
::
lo According to a different embodiment, it is possible to use independent rings 30 according to methods that will be described in detail hereinafter.
In practical use, after arranging the nets side by side, a joining element, constituted either by the spiral 15 10 or by the joining element 20, is inserted from the outer face of one of the nets until it exits from the outer face of the furthest adjacent net.
In this manner, the joining element, the axial length whereof is preferably equal to the height of the nets, 20 engages the outer face of the net from which said joining element is inserted.
Once the joining element has been inserted, a locking element, constituted by a locking bar 40, is applied and inserted either in the turns of the spiral 10 or in the 25 interconnected rings 21 protruding from the outer face of the furthest net.
In this manner, the locking element is in practice retained between the outer face of the net and the part of the joining element that protrudes therefrom.
Optionally, as illustrated for example in figure 11, 6 ~ ?~ 7 7 it is possible to apply a second locking element between the outer face of the net through which the joining element has been inserted and the joining element itself, thus forming an additional reinforcement element.
Use of two locking elements is instead necessary if the independent rings 30 are used, as shown schematically in figures 14 and 15, where there are two locking bars 40 that are arranged substantially parallel to each other and are optionally obtained by bending an iron rod 50 so that 10 it becomes U-shaped.
In this solution it is possible to use independent joining rings, designated by the reference numerals 30a and 30b, which are arranged above and below, and optionally an intermediate independent joining ring 30c, and it is also 15 possible to place only two independent rings arranged above and below the regions affected by the nets, since the purpose is to form a joining and stiffening element in the placement of the two locking bars.
According to a different embodiment which is 20 conceptually linked to the preceding ones, it is also possible to use the spiral-shaped element 10 by screwing it between the two nets 1 and 2, which are advantageously arranged side by side in a limited region, as illustrated in figures 16 and 17, and by screwing the spiral-shaped 25 joining element so that its various turns in practice surround and engage the horizontal portions of the meshes of the two nets, thus forming the joint directly without necessarily having to apply the locking bar, since the joining element itself provides the locking action.
It is fundamentally important for all the above 7 2 ~ 7 described solutions that the nets are joined without providing a preliminary interpenetration of the nets, consequently allowing to considerably simplify all the coupling steps and allowing to produce the most disparate 5 structural configurations, since it is possible to mutually overlap more than two nets, thus obtaining, in the forming of the cells, the most suitabla arrangement ~or the particular type of reinforcement to be provided.
To the above, for the sake of completeness in 10 description, it should be added that the pitch of the turns of the element 10, as well as the mutual distance between the interconnected rings 21 of the joining element 20, must be equal to, or in any case a submultiple of, the pitch of the meshes, thus allowing very easy insertion, since once 15 the nets are overlapped there are no obstacles to the insertion of the joining element from one net toward the other net, allowing easy exit for consequent locking.
Since the turns have a pitch matching the spacing of the meshes, an equally simple installation is obtained if 20 the joining element is applied by screwing.
The invention thus conceived is susceptible to numerous modifications and variations, all of which are within the scope of the inventive concept.
All the details may furthermore be replaced with other 25 technically equivalent elements.
In practice, the materials employed, as well as the contingent shapes and dimensions, may be any according to the requirements.
As it is known, cellular structures for containing 5 loose materials to stabilize and reinforce soils, commonly termed "geocells", are formed by means of nets that are mutually joined so as to form closed spaces in which loose materials, such as gravel and the like, are introduced.
For example, patent GB 2,078,833 discloses a structure 10 in which the joint is provided by means of a system known in the art as "bodkin".
