Description

Perforated, welded, textured or non-textured material cell, for incorporation into alveolar containment system.

Object of the invention

The present invention refers to a reinforced cellular material whose surface has been perforated, textured or not, for incorporation into a containment system, conceived for the containment of any type of material, such as concrete, soil, floors, cements, cements asphalt, or plant materials; and to build structures or bases of roads, earth slopes, landfills or other civil engineering structures. Said alveolar containment system is designed, especially, for the construction of roads in places with different types of problematic soils, such as sandy or desert that difficult construction, foundation or base work for them.

The indicated alveolar containment system also serves the purpose of protecting and stabilizing the uneven ground, river channels or hydraulic structures.

Specifically, the present invention refers to a welded material with openings or perforations in and along its central part, which allows, by means of the indicated openings or perforations, the roots, sand, earth, materials to pass through them granular, aggregate or vegetable, pipes and cables, interacting with all of them.

Background in the state of the art

An alveolar material for covering the earth is known in the state of the art in order to provide a base for road or road.

In the E90300099 patent "Textured cell material to confine concrete and earthy materials" mention is already made of a cellular material where the cells are made of plastic strips joined by their faces in a juxtaposition relationship with alternate separation spaces, so that when the strips are tensioned in a direction perpendicular to their faces, the resulting cell section looks similar to a honeycomb or honeycomb, with sinusoidal or undulating cells. Even, it is stated in said patent, self-supported walls have been constructed with the cells that are formed with the union of said cellular material.

European patent number EP93120149.5 "Reinforced cellular material" -with reference to patents EP-A0378309 and EP-A-0378379-claims a structure of cellular material for con fi rming concrete and earth materials, said cellular material structure comprising a series of plastic strips joined together, which include openings that are essentially coincident and are located next to the joining areas and below the midpoint of the faces of the strips.

Said openings are also incorporated in the proposed invention, but with a different number, position or configuration and diameter, which greatly influences the use and capacity of said cell.

Thus, the number, arrangement and diameter of the indicated openings in the proposed invention, and in equal density with respect to what is previously known in the state of the art, provides the cell in question, and the system of cellular con fi nance to the that it is incorporated, a greater resistance to rupture, and better interaction with the elements with which it is related (earth, sand, concrete, roots, etc.) that may be introduced by them.

Furthermore, with the con fi guration claimed with the present invention, the elastic limit of the cell is much greater, having a plastic behavior before the rupture occurs, which the previously known is lacking.

The diameter of the openings or perforations, described below, furthermore, allows a better and greater irrigation or interaction with the filling materials of the alveolar containment system, especially with those of greater diameter such as gravels, ballast and concrete; but also with plant soils, such as roots, which has been proven and in relation to the proposed invention, which pass through the cells, through their openings, more easily and to a greater extent.

In addition, said modification allows the insertion of metal bars through their openings, for the assembly of the alveolar containment system, in all types of diameter, warp or weft, before the concrete filling is carried out, preserving its flexibility or semi-flexibility. -flexibility, which does not occur in previous patents.

The new welded material also allows its use in arid areas where vegetation is required, by inserting tubes or hoses of variable diameter, in order to provide the necessary moisture to the ground. It is also possible the contribution of nutrients, through this series of tubes or hoses, to the vegetation and for an optimal and rapid development of the bacterial fl ow and vegetation.

The use of this material for containment of aggregates and concretes in the bases of the road, through the insertion of tubes, allows the addition of adhesives, binders or bitumen that improve the cohesion of the soil particles of the base of the road or road .

The use of this material in landfills and deposits allows a better detection of liquid leaks, by inserting detector cables through their openings.

Explanation of the invention.

The cell of welded and perforated material, textured or non-textured, for incorporation into a cell con fi nation system is manufactured from strips of plastic polymer, provided with flexibility and with a tensile strength in longitudinal traction equal to or greater than 10 kN / m

The cell in question can be subjected to a texturing process or be presented smoothly, or without any relief.

In the event that the faces of the cells undergo a texturing process as described in US Patent No. 4,965,097 "Textured cellular material for concrete and earthy materials con fi nation", this consists in that the surface of layers of polymer strips, which improves the friction angle between the textured surface and the irregular surface of the adjacent filling material, thus achieving a substantial improvement in the load bearing capacity with which the filling system is filled cell con fi dence of which they are a part, which, as stated, interact with those materials with which the con fi nation system is filled, such as sand, concrete or aggregates. With this drilling and texturing process, in addition, a longer life of the cell is achieved, and an improvement against the risks of sinking by pressure of the material that serves as the base (sand, concrete or asphalt) the aforementioned alveolar containment at that the cell object of this invention is incorporated.

The degrees of perforation and texture of the surface may vary as well as the perforation and texture itself may or may not be uniform, depending on the use to be given to the cell, and the material that will contain the containment system alveolar to which it is incorporated.

The cell will be manufactured in sheets of 2 to 50 cm. height and 2 cm. at 200 cm wide and from 0.1 to 2 mm. thick

The con fi guration of the openings or perforations is parallel both in those placed horizontally and vertically, and equidistant from each other. The distance between the perforations will be proportional to the height of the piece

or to that of his strips.

The openings or perforations will be made with a diameter between 18 to 90 millimeters, which allows incorporating, as already said, an irrigation system, reinforcement, leak detection or drainage system, as well as providing greater resistance to breakage of the cell, with respect to other products known in the state of the art. The openings or perforations can be made in any shape, for example square, triangular, elliptical, star, sun, among others, as well as any size.

The cell will have at least two openings or perforations, its maximum number being unlimited, in response to the user's needs.

2. Statement motivated according to articles 29.6 and 29.7 of the Regulations for the execution of Law 11/1986, of March 20, on Patents on novelty and inventive activity; quotes and explanations in support of this statement The object of the present invention is a process for preparing a thermal projection contribution material containing porous granules, the resulting granules and the use of said material as a contribution material to produce material coatings. Document D01 describes a procedure for obtaining an Al2O3 / SiC nanocomposite to produce coatings of materials by plasma projection techniques. Said process comprises the dispersion in water of SiC, the addition of Al2O3 and a dispersing agent, its mixing by attrition grinding, its freezing and drying under vacuum and the selection of the dried granules (section 2.2). Document D02, relating to the characteristics and properties of preformed ceramic coatings by spray drying, describes a method of obtaining said coatings comprising the stabilization of a ceramic suspension by means of an anionic dispersant and a binder and then its spray drying (section 2). Document D03 discloses a process for obtaining nano-sized ceramic granules comprising the stabilization of a ceramic suspension, consisting of a ceramic material dispersed in water, a dispersing additive and a binder. Next, the atomization of said suspension, its freezing, the sublimation of the frozen water contained in the resulting granules, their drying and the selection of said granules according to their granulometry (Experimental, Table 2). The object of claims 1-30 differs mainly from documents D01-D03 in that none of said documents discloses a method of obtaining a spherical granulated feed material with a range size of 5 to 150 micrometers from suspensions of ceramic powders atomized in a cold environment and dried by lyophilization. In addition, it would not be obvious for a person skilled in the art to develop said procedure from the cited documents. Consequently, the object of claims 1-30 is considered to be new and involves inventive activity as set forth in Articles 6.1 and 8.1 of the L.P. State of the Art Report Page 4/4
