Definitions

• the object of the present invention is a containment module applicable as an auxiliary containment and fixation element in the execution and conservation of embankment, clearing, walls, etc., and more generally for the construction of various types of civil works.
• the field of the invention therefore, is the manufacturing industry of prefabricated concrete modules for construction.
• a plurality of prefabricated pieces are currently known, which are primarily intended for the formation of walls.
• a first technique is called Tierra Armada, and uses flat plates of reinforced concrete that are placed vertically to form a wall that contains the ground. The thrust of the same on the plates is balanced by the traction that is generated in horizontal strips of a certain length anchored in them, as a result of their friction with the surrounding terrain.
• the containment module of the present invention solves the above drawbacks since, on the one hand, it does not require any concreting or subsequent operation and on the other, the L-shape itself of said module allows counteracting both vertical and horizontal forces , thus achieving a total fixation of the land in the area of action. Consequently, we obtain a complete solution reducing materials, specialized labor, necessary machinery and thus reducing costs and execution time.
• the containment module of the present invention is intended, in general, for its installation, with a rotating excavator, which allows the three necessary tasks: prior excavation and preparation of the support esplanade, placement of the piece in its definitive location and subsequent filling, thus avoiding the use of an auxiliary crane.
• the containment module of the present invention is manufactured in such a way that it is suitable for land containment work in civil works, that is, it has the dimensions and strength required for the containment of lands subject to various stresses that tend to deform them.
• it is made of prefabricated reinforced concrete, varying the amount of steel to be assembled in relation to the value of the said acting tension and this, in turn in general, with the height of the earth that supports the pieces.
• a preferred embodiment is the aforementioned reinforced concrete, it would also be possible to manufacture it in other materials according to each specific use, such as plastic to play construction games in the sand of the beaches. Note that in this case corresponding to semi-saturated sands, the friction requirement is lower due to the meniscus forces that previously hold sand grains together, and therefore the support side may be smaller.
• the module of the invention is essentially L-shaped with a section long and a short section substantially forming a right angle between them and their union being reinforced by a chamfer.
• the lower surface of the long section has a rough texture.
• the length of the long section is approximately 80% greater than that of the short section.
• the long section of this module (which is placed in a horizontal position as a rule) allows to increase the stability before the vertical forces, distributing the load and thus reducing the tension acting on the ground.
• the short section (consequently placed vertically) will also increase the horizontal stability, resisting horizontal thrusts by friction provided by the bottom of the piece with the ground.
• the module provides a complete and fixing joint action in the area where it operates.
• the modules can be grouped in various ways: laterally attached, one on top of the other to form a high-rise wall, staggered in the form of a slope, etc., depending on the type of solution sought for each problem.
• the containment module comprises holes in its lateral faces to allow the connection of two adjacent modules attached by means of the aforementioned rounds. It is thus possible to form a straight wall where the modules are connected to each other. Also, as will be explained later in this document, curved walls could be built.
• the containment module comprises holes located in the upper and lower portions of the short section to allow the joining of overlapping modules. This allows the union of a module that is placed on top of another for the formation of walls or stirrups.
• the containment module may comprise holes in the front and rear end edges of the long section to allow the joining of facing modules - for example on raised platforms without increasing width - by round steel of a certain length. length anchored in the holes with resin.
• the module of the invention preferably comprises two mechanics located substantially in the center of the long section and in the center of the short section respectively, in order to avoid the destabilizing effect of the sub-pressures that the infiltrated water can cause.
• another preferred embodiment of the invention is directed to a module whose long section has a thickness that decreases in the direction of its free end. That is, the long section is "sharp", which allows its placement on the ground by means of a "driving" procedure. This procedure allows to install the modules in a simple, fast and above all, without having to carry out a previous excavation that can cause the collapse of the area in very precarious equilibrium cases.
• the length of the long section decreases or increases in the direction of its free end. That is, the long section or base of the module becomes trapezoidal.
• each module can be attached to the adjacent module by means of the steel rounds described above.
• FIGURES Figs. 1a and 1b respectively show a top and bottom perspective view of the containment module of the present invention.

It is observed how the long side (2) and the short side (3) are joined forming an approximately right angle, where a chamfer (4) is incorporated to ensure the joint.
• the base (5) of the long section has a rough surface to increase friction with the ground and thus avoid the running of the module of the invention.
• the holes (6a, 6b, 6c) located in the side edges of the module (1) allow joining several modules (1) adjacent to each other
• the holes (7a, 7b) located in the upper and lower edge of the Short section (3) allows to join several modules (1) superimposed on one another
• the holes (8a, 8b) located in the front and rear edge of the long section (2) allow to join several modules in two relative positions: one forming a "shortened” T and another forming a "channel” attached to the piece in L (1).
• Fig. 2 shows an example of a wall formation, for example for the formation of a bridge or trench.
• the superstructure (100) of a bridge that rests on a volume of land is supported by four modules (1) according to the invention.

• Fig. 3 shows an example of the formation of a green wall suitable for gardening or the construction of housing developments using the module (1) of the invention.
• the modules (1) are arranged stepwise, each of them holding a part of the total land volume. This construction allows trees or other vegetation to be arranged in the horizontal space that remains between one module (1) and the next.
• Fig. 4 shows an example of construction of a breakwater wall suitable for water channels or for erosion protection. The modules (1) are arranged in a manner similar to that of Fig. 3, although in this case the horizontal space between one module (1) and the next is filled with breakwater.
• Fig. 5 shows an example of a road elevation (101).
• Two rows of modules are used, arranged one above the other, leaving the ground trapped between them.
• the modules are joined in the direction of the road (101) by means of steel rounds that are housed in the holes (6a, 6b), while the vertical connection is made thanks to the holes (7a , 7b).
• each two modules facing each other can be joined using round ones of a certain length that are fixed by resin in the holes (8a, 8b). It is thus possible to raise the road (101), for example directly above an existing road (101 '), without the need to extend the width of the road. An improvement in the drainage of the track is also achieved.
• Fig. 6 shows how the module (1) of the invention can be used for the correction of landslides in embankments.
• landslides are detected, for example when cracks (102) are discovered next to the road (101) in coronation or on the support, several modules can be placed with the long section (2) in the direction of the road (101) to serve as land support.
• Fig. 7 shows how modules (1) are used to correct landslides in clearings. In this case, the long section (2) is in the opposite direction to the road (101), thus leaving the volume of land that constitutes the perfectly secured clearing.
