Abstract
Abstract Protecting systems for coasts, breakwaters, slopes, dikes, sand dunes and similar, and more particular improvements in self-locking blocks forming component elements of protection structures against erosion, to the process of assembling said structure, as well as the resulting structure. The purpose is to afford a structure adapted to counteract the destructive and erosive action of external physical phenomena, such as wing, water, and the like, with respect to coasts, slopes, breakwaters, dikes and sand dunes.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
223 words
In self-locking blocks constituting component elements of protecting structures against erosion; the improvement comprising in that each said block includes a body defining two planar surfaces of selective setting extending substantially parallel to each other, said surfaces forming a double T-configuration comprising two heads of diverging and symmetrical sections, and a core joining said heads; two lateral external faces disposed in the ends of the heads and the proximate sides of the core, respectively; and two internal lateral faces in each head, which are located between lateral external faces of said heads, and lateral faces of the core, said lateral faces of the core and heads extending transversally of the planar surfaces for the support of a selective block and being of the length of said core so as to be equal to the sum of the distance between the lateral internal face and the lateral external face of both diverging sections of said heads, the lateral faces of the core being bent towards one of the planar surfaces of the block, whereas the lateral external faces of the heads are bent towards a direction opposite to the direction of said lateral faces of the core to enable locking a plurality of said blocks to each other in a direction extending perpendicular to the plane defined by the orthogonal axes of each block.
Claim 2
Dependent Claim
223 words
In self-locking blocks constituting component elements of protecting structures against erosion; the improvement comprising in that each said block includes a body defining two planar surfaces of selective setting extending substantially parallel to each other, said surfaces forming a double T-configuration comprising two heads of diverging and symmetrical sections, and a core joining said heads; two lateral external faces disposed in the ends of the heads and the proximate sides of the core, respectively; and two internal lateral faces in each head, which are located between lateral external faces of said heads, and lateral faces of the core, said lateral faces of the core and heads extending transversally of the planar surfaces for the support of a selective block and being of the length of said core so as to be equal to the sum of the distance between the lateral internal face and the lateral external face of both diverging sections of said heads, the lateral faces of the core being bent towards one of the planar surfaces of the block, whereas the lateral external faces of the heads are bent towards a direction opposite to the direction of said lateral faces of the core to enable locking a plurality of said blocks to each other in a direction extending perpendicular to the plane defined by the orthogonal axes of each block.
Claim 3
Dependent Claim
53 words
Improvement in self locking blocks component elements of protecting structures against erosion; according to claim 1, characterized in that each block is affected by at least a through perforation in the longitudinal sense, in the nature of passage of a stringing means for the different blocks constituting one and the same protecting structure.
Claim 4
Dependent Claim
81 words
Improvements in self locking blocks component elements of protecting structures against erosion; according to claim 1, characterized in that, in longitudinal sense, each block is affected by a perforation open in both ends, which in a continuous manner comprises all the length of the intermediate wall and is extended through the transversal walls to finish opening in the head faces of the transversal walls, forming the passage for a cable stringing the different blocks constituting one and the same protecting structure.
Claim 5
Dependent Claim
96 words
A protecting structure against erosion, formed by employing the elements of claim 1, characterized by comprising a plurality of elements couplable one to the other, which constitute mutually locking chaining, resistant to traction according to two axes aligned oriented in the sense of the length and width of said blocks and a locking effect according to a third ax transversal to the first two being the same blocks furthermore resistant to shear in accordance to one of said axes corresponding to the sense of the tide; said structure being supported on a filtering permeable material layers.
Claim 6
Dependent Claim
44 words
A protecting structure against erosion, formed by employing the elements of claim 1, characterized in that it is arranged covering a slope which gradually penetrates in the mass of water, down to a sufficient depth, with the insertion of a filtering permeable material layer.
Claim 7
Dependent Claim
73 words
A protecting structure against erosion, formed by employing the elements of claim 1, characterized in that it is arranged covering a slope which gradually penetrates in the mass of water down to a sufficient depth, with the insertion of a filtering material layer; the protecting structure including at least a member which, projected into the slope, penetrates into the zone corresponding to its highest level, in the nature of an antisliding retention means.
Claim 8
Dependent Claim
32 words
A protecting structure against erosion, formed by employing the elements of claim 1, characterized in that it is arranged forming a horizontal wall, with the insertion of a filtering permeable material layer.
Claim 9
Dependent Claim
26 words
A protecting structure against erosion formed by employing the elements of claim 1 characterized in that the filtering permeable material is constituted by a geotextile membrane.
Claim 10
Dependent Claim
143 words
A protecting structure against erosion formed by employing the elements of claim 1, characterized in that the blocks coupled one to the other and constituting mutually locking chainings, resistant to traction in the sense of their aligned axes according to the length, width and a third ax oriented in a transversal sense to the first two one furthermore resistant to shear according to one of said axes which corresponds to the sense of the tide, constitute rows in which the longitudinal perforations of the blocks are respectively aligned, forming in each row a continuous passage common to all of them; and said continuous passages in each row, are passed through by a stringing cable, which ties also the different rows of blocks one to the other, through end bendings of the same cable in the positional transition from one to the other passage.
Claim 11
Dependent Claim
185 words
A process for assembling and placing the protection structure of claim 5; characterized by comprising the following steps; arranging the different component blocks of the one and same structure, forming rows of blocks mutually locked one to the other, and also locked between one row and the other; inserting a steel cable through the continuous passages, forming bendings of said cable in the ends of each outlet of said passages, in such a manner that the stringing cable is, as a result, configuring in plane a "zig-zag" path; finishing the ends of said cable in such a manner as to immobilize them against the protection structure; on the other hand, constructing a supporting frame, dimensioned compatibility with the limits of the protecting structure, and vinculating one to the other; on the emplacement bed for the structure, forming a filtering permeable material layer; finally, hoisting the structure suspending it by means of said frame, and lowering it down to said emplacement bed, leaving it supported thereon, previously to which one of the axes of said blocks is oriented in accordance to the sense of the tide.
