Abstract

Stabilizer of coastal deposit forms, for the retention of coastal sediments, which is formed by a dike (1), which is at least partially submerged under the coastal water, and which in turn has inside, ready to along its length, a retention wall (2) of sediments Coastal This retaining wall (2) is composed of a pair of peripheral layers (3) parallel and separated from each other, between which a waterproof layer (4) is housed, which is what retains the coastal sediments.

Technical Field of the Invention

The present invention belongs to the technical field of civil engineering, specifically with regard to maritime and port engineering, in its sustainability section of coasts, and more specifically to the constructions for the coastal sediment retention thus preventing the loss of said sediments and regression of the coast.

Background of the invention

There are currently different means to avoid erosion and regression of the coasts, or at least, mitigate these. One of these methods is the placement of a breakwater or dike submerged in unstable coastal sections, at a distance from the coast determined according to the profile and conditions of the coastal section, so that retention is possible of a percentage of sediments that would otherwise be lost and they would cause the regression of the affected coastal section.

The size of the materials to be used for the realization of the submerged dike varies depending on the conditions of the coastal section, and in all the used a filtration takes place of sedimentary material through said submerged dike, which it produces a non-evaluable sediment loss and that causes this solution adopted to stabilize the coastal section is not effective.

It was therefore desirable a system that achieve efficient retention of coastal sediments, avoiding the inconvenience existing in the previous systems of the state of the art, and avoiding, or attenuating at least the regression of the coastal sections.

Description of the invention

The present invention solves the problems existing in the state of the art by means of a stabilizer coastal forms of deposit, for sediment retention coastal, which is formed by a dike at least partially submerged under the coastal water, and that has inside, arranged along its length, a retaining wall of coastal sediments. This retaining wall of coastal sediments It is formed by a pair of parallel and separate peripheral layers each other, including a waterproof layer (4).

Preferably, these peripheral layers of the retaining wall is formed, each of them, by a plurality of sheet piles that are nailed to the bottom (5) of the coast, thereby ensuring efficient fixation of these.

In addition, the inner waterproof layer of the wall retention is made of clay, facilitating this material sediment retention, which prevents, or at least attenuates the maximum regression of the coasts.

Depending on whether the coastal fund is classified as hard or soft, the dike of the present invention it will rest directly on said coastal bottom, or on a layer filter previously placed on the coastal bottom.

Description of the figures

Then, to facilitate the understanding of the invention, by way of illustration but not limitation, will be described an embodiment of the invention that refers to a series of figures.

Description of preferred embodiments of the invention

As can be seen in the figures, the object of the present invention is a form stabilizer coastal deposits, for the retention of coastal sediments and avoid the loss of these sediments and the regression of the coast That this entails. The stabilizer is formed by a dam 1, the which is at least partially submerged, and preferably fully submerged under coastal water. This dike 1 has in its interior, along its entire length, a retaining wall 2 of coastal sediments, which is the element responsible for avoiding The loss of these elements.

The retaining wall 2 is formed by a pair of peripheral layers 3 parallel and separated a certain distance, between which a waterproof layer 4 is housed, which is what retains sediments.

The figures show preferred embodiments of the invention, in which each of the peripheral layers 3 of retaining wall 2 is formed by nailing sheet piles at the bottom 5 of the coast, until they are embedded in the bottom Marine. These sheet piles are made of a suitable material to prevent corrosion in a marine environment, preferably in PVC The material of the impermeable layer 4 is preferably clay, achieving with this material an optimal waterproofing

Depending on the bearing capacity of the fund 5 in which the stabilizer of coastal forms of deposit, there will be two different embodiments for the aforementioned object of the invention.

Figure 1 illustrates the first one, in the that the stabilizer of coastal deposit forms is applied in a 5 coastal hard ground. In this embodiment, the sheet piles of retaining wall 2 will be driven into bottom 5 of the coast, supporting the blocks that make up the submerged dike 1 directly in said fund 5.

Figure 2 illustrates an alternative embodiment, in which the coastal deposit forms stabilizer is applied on a coastal background 5 of soft ground. In this embodiment, the sheet piles of retaining wall 2 will also be stuck in the bottom 5, while a filter layer 6 will be placed on said bottom 5 of the coast, on which the elements of the dike will support 1 submerged

Once the invention has been clearly described, notes that the particular realizations above described are subject to modifications of detail provided that do not alter the fundamental principle and the essence of the invention.
