disclosure

The articulated structure for soil protection and reinforcement, is formed by blocks or resistant bodies, of trunk-conical and / or cylindrical polyhedral volumes, linked together, in two orientations (orthogonal or oblique) of the same plane, by means of resistors. connective cables, ropes and / or wires, or other types of connective elements 5 designed to pivotably join the sturdy blocks or bodies of the flexible structure. This structure, by its geometric design, can be placed on the surfaces to be protected, in a single layer or in several overlays, taking as a whole the geomorphological shape or development of the substrate to be protected.

Once the different components of the version of the invention, developed to explain its nature, have been established, the description is then complemented with the functional and operative relationship of its parts and the result they provide.

In order to achieve an articulated surface development structure for soil consolidation, 1 and / or 3 resistant blocks or bodies of interlocking trunk-conical and / or cylindrical polyhedral volumes 20 are provided in two orientations (orthogonal or oblique). of the same plane by means of sturdy connective cables, ropes and / or wires 2, or other types of connective elements designed to jointly join the sturdy blocks or bodies 1 and / or 3 of the flexible structure ( Figure 1) . This structure, by its geometric design, can be placed on the surfaces to be protected, in a single layer or in several overlays, taking as a whole the geomorphological shape or development of the substrate to be protected (Figures 6, 7 and 8). This articulated surface development structure proposed by this patent has the characteristic that it can be used indistinctly for both hydraulic and road use, either to protect 35 soils or beds and / or structures, the layers of the articulated structure fit a on the other, provided that the lower body parts of blocks 1 and / or 3 of an upper layer fit into the inter-block spaces i forming the upper body parts of blocks 1 of the underlying lower layer.

The physical contacts of the blocks of an upper layer form, with the blocks of a lower layer, a locking between layers, such that the forces or actions are partially transmitted and / or transferred from one layer to the other. If this structure is used for reinforcement or consolidation of underwater soils and / or structures, the inter-space i layered creates perfectly delimited chambers, where the flow velocities of the hydraulic currents from the upper layer occur, because From its particular design the articulated structure has a high permeability value and hydraulic transmissibility.

The hinged structure placed on a layer of granular soil and / or plastic cement soil and / or directly on the subrasante and filled interlocking spaces i 20 with resistant materials, can allow vehicle transit, transferring to the substrate s through the blocks and Filling the vertical loads and horizontal loads for the resistant mesh 2, the materials that must fill the interblock spaces i to achieve the bearing surface may be composed of granular soils - or asphalt mixtures p or other resistant material rolling loads.

The blocks 1 of the articulated structure may have both upper and lower conical trunk bodies 30 (Figure 4) or the upper body a pyramidal trunk volume 3 (Figure 5), the latter being a surface or public block; however, the lower body is of a cylindrical or pyramidal conical shape volume with the object that the articulated structure is jammed in the supporting substrate. Likewise, this type of floor may be layered, with or without intermediate filling of granular soils g and / or asphalt materials, and / or interlayer plastic soils. (Figures 6,7 and 8)

Thus one of the constructive possibilities that lead to the embodiment of the invention and the way in which it works has been highlighted, complementing the documentation with the synthesis of the same contained in the following appended claims.
