Description

The retaining wall of land that is recommended

Land containment module.

Object of the invention

The present invention refers to a land containment module, preferentially and fundamentally provided to build the classic breakwaters, land containment walls that are placed in terraced terraces and terraces, being equally applicable on the coasts to prevent water erosion on land, on the banks of rivers, etc.

The object of the invention is to achieve an easily achievable retaining wall, with optimum stability, preventing displacements of the parts that constitute it and therefore supporting the force that the earth can exert on its landslides.

Although it has previously been said that the retaining wall is intended for, for example, breakwaters, river banks, bank-type steps, it can be applicable in any circumstance in which land containment is to be carried out, whether stable or not, as well as for public works or other building works.

Background of the invention

Normally the retaining walls are made of large-sized stone blocks, which are placed forming an inclined wall in correspondence with the inclination of the land, so that these stones are placed trying to “marry” each other, of the best possible way, fixing each other by mutual friction.

Among the problems and inconveniences that arise in this type of construction of retaining walls, the following can be mentioned:

-

The stone blocks work by friction, as has been said before.

-

There is a remarkable real weight of the retaining wall.

-

In principle, the technician cannot know, for sure, if the operator who is currently at work will know how to choose the appropriate stone blocks and arrange them in the most suitable position for his work.

-

Reliability in achieving stake out according to the execution project is not most appropriate.

-

The resources needed to carry out these works are very expensive and burdensome.

-

The need to have to look for the blocks of natural stone creates an added difficulty, to which the familiar deterioration of the environment can be added.

-

It must be taken into account that the execution of the work must be permanently monitored by highly qualified technicians.

Well, part of the problems and inconveniences referred to above, are solved using, instead of the classic blocks of natural stone, precast concrete stones, although the disadvantage is still maintained that the blocks are linked to each other through friction, that is to say, they work by friction, also maintaining the high costs in the realization of the work, and of course the control of its execution.

It has been designed to solve the above-mentioned problem, based on using, instead of the classic natural stones or prefabricated concrete blocks, hollow plastic parts that are tongue and groove interconnected with each other and that once mounted simply, due to their reduced weight , can be filled with concrete, allowing even the introduction of steel reinforcements through them, thus strengthening the mechanical strength of the wall.

More specifically, the wall is formed from a foundation, which can be straight, sinuous, curved, right angles, corner or corner, buttresses and pilasters etc, depending on the characteristics of the land, so that on said foundation Initially, different rows of modules are placed, with a tongue and groove intercouple between them, making it impossible for them to move horizontally against the pressure of the earth.

On the original foundation a first course based on foundation base plates is placed, consisting of triangular structures in which two hollow cylindrical bodies are established, in correspondence with two of the vertices, while on the other vertex there is an oval body and slightly smaller, these foundation plates joining each other conveniently on the original foundation, so that on that foundation plate course a first course of base modules is mounted, which being equally hollow have a cylindrical foot pluggable into one of the cylindrical housings of the foundation plate, so that those foundation modules that will constitute the first course have a variable inclined plane on their front face according to the necessary slope to constitute the exposed face of the retaining wall that can vary in shape and colors according to the designer, while on the back they incorporate a pair of horizontal projections whose function will be exposed later.

Once that first course of foundation modules is mounted, a second course of other modules is placed, with the same characteristics as the previous ones but instead of having a cylindrical foot for overlapping in one of the cylindrical bodies of the foundation plate, it has a cylindrical foot of greater length and smaller section for coupling on the hollow and oval body established in the foundation plate and in the triangular structure located on the original foundation, so that that cylindrical body of smaller and elongated section passes behind of the foundation module of the first course.

After the assembly of that second course of the foundation modules, another course of type modules is mounted, of analogous characteristics to the two previously mentioned, but which instead of the cylindrical body include a lower extension in inverted “T” that is positioned of form embedded between the projections that constitute the horizontal and posterior projections of the foundation modules of the first course, thus establishing a tongue and groove coupling that prevents relative sliding between modules, both horizontally and vertically.

The modules that form the wall thus constituted can have their flat lateral faces, when the retaining wall is straight, but said faces can have an angular or other configuration to be able to make curves in the path of the wall, which can be concave or convex.

The construction system based on which the wall is obtained, according to the invention, allows the disassembly of the different modules, without using support pads between modules, to release them in their disassembly. Description of the drawings

To complement the description that will then be made and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical implementation thereof, a set of drawings is attached as an integral part of said description. where, for illustrative and non-limiting purposes, the following has been represented:

As can be seen in the aforementioned fi gures, the containment module object of the invention is obtained by assembling or assembling tongue and groove together a series of modules and elements that will be exposed throughout this description, all from of a foundation (1) on the ground, in which in the first place a base constituted by integrating foundation plates (2) is provided, defining a triangular structure in which two of its vertices are determined by cylindrical bodies (3), hollows, and the other vertex formed by a body (4) also hollow, of smaller amplitude or section and oval contour, so that said foundation plates (2) are arranged on the foundation itself (1) made for this purpose, so that both the foundation plate (2) and the rest of the modules that participate in the wall are made of plastic, hollow, capable of being mounted after receiving concrete and even a metal reinforcement to give stability and resistance to the whole.

Well, on that base formed by the foundation plates (2) a series of foundation modules (5) are mounted that will constitute a first course, also formed by hollow bodies, with a lower and cylindrical extension or projection

(6) intended to be housed in one of the cylindrical parts or bodies (3) of the foundation plate (2), allowing the module (5) to rotate so that it can be conveniently positioned.

After the first course formed by the modules (5) mentioned above, the arrangement of a second course based on modules (5 ') with the same characteristics to the modules (5) is carried out, but instead of the cylindrical projections (6), have projections (6 ') of notable greater length and shorter section, intended to be arranged, behind the modules (5) and coupled, by their lower end, to the oval bodies (4) of the foundation plate ( 2), as shown in the exploded view of the figure

9.

After the arrangement of these modules (5 ') of the second course, it can be said that the foundation is made, then providing another course of type modules (7), which are also of hollow configuration and are provided with a pair of projections posterior (8) and a lower extension in inverted "T" (9), presenting its inclined anterior plane (10), as can be seen clearly in Figure 2, in which the hollows can also be observed

(eleven)

which presents the constituent body of the module

(7)

referred.

In relation to the base modules (5), in addition to the cylindrical projection (6) below and its corresponding inclined plane (13) on its front face, it includes a pair of projections or rear projections (12), characteristics that are repeated in the module (5 '), with its front and inclined face (13'), its projections or rear projections (12 ') and its elongated and oval projection (6').

Therefore, the realization of the retaining wall is carried out by first laying the foundation plates (2) on the foundation (1) and on these the modules (5) that are to form the first row, plugging the lower cylindrical projections (6) of these in the cylindrical bodies (3) of the plates (2), to then form the second row with the modules (5 '), plugging the oval and elongated projections (6') into the oval bodies (4) of the plates (2); with provision of these oval and elongated projections (6 ') of the modules (5'), after the modules (5), to finally arrange the type modules (7), whose projections or rear projections (8) are interlacedly arranged, as if it were a tongue and groove coupling, between the rear projections (12 and 12 ') of the modules (5 and 5'), all without the possibility of movement between modules, both horizontally and vertically.

Finally, to say that in order to enable disassembly, support pads (14) are provided between the modules, as can be clearly seen in Figure 3, so that based on these pads (14), it is possible to easily carry out the Disassembly of any other circumstance is necessary to carry out the je of the different modules and therefore of the disassembly wall. containment, in case of necessity or by which

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 1.-Technical problem. The inventor describes in his application "Land Containment Module". The use of stone blocks or precast concrete pieces, linked to each other by friction, raises the cost of work and execution control of it. 2.-Proposed solution. The inventor proposes the use of prefabricated hollow plastic parts, capable of being filled with concrete and armors, which are mutually coupled to each other. 3.-Claims. The request consists of 4 claims, the 1st of which is independent and the rest dependent. The first claim includes the fundamental technical characteristics of the invention. The second claim relates to the use of foundation plates and hollow plastic modules. The third claim refers to different forms that the walls can take. The 4th claim refers to the element used for the purpose of dismantling the wall. 4.-Novelty and Inventive Activity. Of the documents cited in the International Search Report, it is considered the closest to the invention, the EP2072688 (D01). D01 discloses a land containment wall, constituted by assembling hollow modules grounded, susceptible to filling with material (See Figs. 4 and 5). Said said interrelated modules with each other, by means of the rod (20), each module (10) comprising two hollow cylindrical bodies (111) in two of its vertices. Riding as many rows of these modules as you want. The structure is anchored to the foundation (40), through penetration of cylindrical stems (20) in it (See Fig. 4). The essential differences between D01 and the 1st claim are: -D01 does not disclose the existence of foundation plates on which rows of modules are subsequently mounted. -D01 does not disclose the presence of three types of modules in the constitution of the wall. -The module disclosed by D01 lacks projection insertable in (111), being the element to be inserted (20) Independent. D02 discloses a hollow plastic module capable of forming a retaining wall from it. Being formed by panels hingedly joined. Being partially submerged in the foundation. (See Figs.) No document cited in the International Search Report, questions in an isolated or combined way the novelty and inventive activity of the 1st claim, nor therefore of the dependents. 5.-Conclusion. Claims 1-4 are new and have inventive activity. (Art. 6 and 8 of Patent Law 11/1986) State of the Art Report Page 4/4
