    Union cell for fixing floating docks to piles
    DESCRIPTION
    Object of the invention
    The present invention relates to a cell or joint element intended to fix floating dams for protection against wave waves.
    The invention is part of the technological sector dedicated to the manufacture and design of floating structures that are installed in ports, marinas and similar sports, for the protection and protection against the action of short-term waves, generated by local wind (waves of wind) and the waves generated by ships and ships (stelae).
    Background of the invention
    Within maritime and port engineering, there is a typology of structures commonly used in ports and marinas, such as floating structures called floating breakwaters and whose objective is to guarantee the protection of the port against short-term waves. In addition, within the port, and sheltered by these breakwaters, there are other floating structures (or not) used for the docking of boats, access of people, loading and unloading to and from the boats, etc. These other structures are called floating docks or swamps, and they differ from the dikes by the object and because the design criteria are different, they are not designed to withstand the direct action of the waves.
    Both structures, being floating, need some device or system for fixing and prevent them from moving freely and drifting. This floating structure fixation system is called the anchoring system, and there are basically three types; anchoring systems that use chains, systems that use piles and systems that use elastic lines.
    A system of anchoring with piles comprises long and slender elements (called piles or stakes), which are driven or nailed to the seabed. To fix the floating structure with the pile a connecting element or device is used.
    In the design of a floating breakwater dike, an expert must take into account that the dynamic forces and induced movements due to the action of the waves are far superior to the actions that may exist on other types of floating structures (docks, bridges , pantalanes, storage tanks, and the like), which do not support the direct action of the waves.

    It is known that the traditional union of the floating structure to the piles is based on a ring or clamp that, anchored on the upper edge or cantile of the floating structure and wrapping the pile, allows the vertical movement of the same. This traditional union system is basically used in floating docks and docks, although other applications have also been found (floating bridges, oyster cultivation platforms, marine energy, liquid market containers, etc.). This traditional or standard union, observed in the current market for pantalanes and floating docks has inside a series of rollers or bearings, usually of nylon, which facilitate the vertical movement of those and reduces friction with the pile. A ring similar to the standard is disclosed in patent documents CN103215915 and KR1312209B1. Currently, this traditional system is beginning to extrapolate to floating docks.
    However, for floating docks whose objective is protection against waves, and based on a series of laboratory tests, it has been found that this traditional system of union is unfeasible due to the high forces suffered by the pile. The forces measured in small-scale laboratory tests produce a higher tension in the pile than is permissible.
    Within the state of the art, the following patent documents are known:
    WO2014189320 A1 (Korea Advanced Institute of Science and Technology), referring to a pile-based system and a simple ring anchored to the outside of the structure (storage tank).
    CN103215915 A (Univ Zhejiang Ocean), aimed at a simple ring that has wheels and is applied to floating bridges.
    KR2011019863 A (Ssemo Company Ltd, Ssemo Co. Ltd), aimed at creating a vertical barrier of low thickness against waves, which works depending on its porosity and draft, and fluctuates with the tide.
    JP04185812 B2 (Goyo Kensetsu KK), aimed at an anchoring system for floating docks, that is, for boat docking.
    JP05840194 B2 (Zeniya Kaiyo Service KK), aimed at an oyster culture system comprising the known simple ring that is used in floating swamps, inside which rollers are arranged to facilitate vertical movement.
    The above documents have a common feature: the union of the floating-pile structure is based on a ring that protrudes from the upper edge of the floating structure.

    One skilled in the art knows that a swamp differs from a dike in that the purpose of that is to dock boats and allow the loading and unloading and passage of people, and is not prepared to deal with the direct action of the waves.
    Considering the above, a union cell has been designed and tested in the laboratory that improves the efficiency (hydrodynamic and structural) of the floating dock anchored piles, with respect to the use of the traditional ring.
    Description of the invention
    This union cell is the result of the development achieved after the completion of a series of small-scale laboratory tests, which were carried out in the wave pool of the Center for Technological Innovation in Edification and Civil Engineering (CITTEC) in To Coruna.
    These tests, based on a floating scale dock, were based on measuring the swell that affects the structure, the transmitted swell (inner zone or shelter area), measurement of forces on the piles, and measurement of movements of the dike.
    In this context, first, a test battery (wave height and period conditions) for the traditional ring was made. The results obtained were compared with those of other authors found in the scientific literature, such as Cox R. and Beach D., 2006, “Floating breakwater performance - Wave transmission and reflection, energy dissipation, motions ad restraining forces”, CoastLab Confenrece . 2006, and Ruol, P. and Martinelli, L., 2007, "Wave flume investigation on different mooring systems for floating breakwaters." Proceedings of Coastal Structure 7 (1), 327-338. All these scientific articles employ the traditional ring in Your essays
    The results showed that the forces that the floating dock transmits to the pile due to the action of the waves, are very high. These forces can exceed the maximum strength of the pile. Also high balance movements (“roll”) of the floating dock were detected.
    Therefore, a new dock-pile joint system was proposed, which is the object of the present invention, together with the two modalities or options for locating said system for joining the floating dock (exterior and recessed). The results achieved through this new dam-pile joint system show a marked improvement in both movements and measured forces.
    Considering the above, the present invention is directed to provide a new junction cell with the objective of fixing floating docks to anchoring piles, which improves the behavior of the floating system against waves.

    The new union cell consists of a chassis, in the form of a hollow cubic body, such as a cage. That is, the cell consists of a chassis of a height equal to that of the dike in a floating position on the sea. Any expert understands that the height of the dike corresponds to the distance of separation between the sides or greater faces of the dike, when it is in a floating position.
    The chassis (cage or frame) is formed from metal bars, based on metal or metal alloy resistant to the action and characteristics of seawater.
    On each of the four inner faces of the chassis, and fixed to the bars that make up the chassis, the cell has some elements of defense and damping that allow, on the one hand, to dampen the impact forces of the waves and, on the other , ensure that the pile is always struck against said damping elements.
    Therefore, unlike the traditional ring, which has rollers that facilitate vertical movement, the union cell of this invention is provided with an adequate defense and damping system against the impact of the piles and waves.
    In addition, in a different way to the traditional ring, which surrounds the pile from the edge or cantile of the floating structure, the present union cell and the damping elements wrap the pile along the entire strut of the floating dock, for its fixing and allow the vertical movement of said pile. Within the naval engineering, strut is defined as the height of the floating structure or vertical distance measured from the lower horizontal face and the roof line or upper horizontal face.
    Regarding the placement of the present union cell with respect to the floating dock, there are two options: one, by external fixation (outer cell); that is, on the minor walls of the dike, and, the other, by means of interior fixation; that is, forming part of the dike itself (inner cell).
    Therefore, the cell, once constructed from the metal bars and the elements of defense and damping, can be placed outside the dam, anchoring one side of the cell to one of the lateral faces (minor walls) of the dike or, according to another option, it is embedded in the dike, that is, the cell is embedded in one side of the dike, after practicing a recess in it.
    Both location options have been tested on a small scale in the laboratory.
    It has been found in laboratory tests that the characteristics of the junction cell described here improve the hydrodynamics or movements of the floating dock and, consequently, the forces transmitted on the pile, with respect to the traditional ring system. By means of the present cell, the movement or balance rotation is decreased

    ("roll") of the floating dock under the action of the waves. This improvement in hydrodynamic behavior implies a reduction in the forces that the pile supports.

    Examples of realization of the invention
    In order to describe how the invention is made, the following examples are described, with the help of the figures cited above.
    The union cell (1) has the purpose of fixing a floating protection dam (2) against waves to some piles (3).
    The union cell (1) is manufactured by configuring a chassis (cage or frame) from metal bars (1a), which are based on a material resistant to the action of seawater. These bars constitute the edges of a hollow cubic body.
    On the inner faces of the chassis are arranged, permanently fixed, some elements (4) of defense and damping, which consist of solid bodies with a high resistance and some elasticity to withstand the impacts of the piles, due to continuous waves.
    According to one option, the joint cell (1) is fixed to the outside of the dike (2), that is, on the strut of the dike, as can be seen in Figure 3 (outer cell).
    Another option is that the union cell, once it has been formed from the metal bars (1a), is embedded in the dike itself (2), by means of a recess made in it (figure 4). Thus, the cell (1) is embedded in the structure of the dike (2). The cajeado consists of a hollow delimited by three solid walls or sides, and is dimensionally shaped to receive the cell and that this

    is fixed to the dike (2), for example, by threaded joint.
    The elements (4) of defense and damping are solid bodies based on a resistant material, which withstand the impacts produced by the pile, due to the waves. By means of these elements (4) of defense and damping an internal hollow is formed in the cell (1), through which the pile (3) is introduced to fix it to the dike (2). The purpose is to fix it, retain it and allow its vertical movement.
    According to figure 5, in which graph the triangles represent the traditional ring and the junction cell of the invention, it can be seen that the forces of the dike on the pile (ordinate axis), in the case of the union cell outside, they are inferior to the force exerted by the floating dock on the pile in case of using a traditional ring. These results are observed for different heights of significant wave (abscissa axis), reaching reductions in 50% impact force. The significant wave height is a statistical parameter that is commonly used in oceanography and with which an average expert in the art is familiar (Hs: arithmetic mean of the third highest waves recorded).
    An expert understands as an impact force that which makes the floating dock on the pile by means of the union, either the traditional ring, or the cell of the invention. It should be clarified that this force has no unity, it is "dimensionless", which is common in the scientific community when displaying laboratory results at scale. The parameter used to "dimensionless" has already been used by other authors, for example, Ruol et al. 2013, in “A Formula to Predict Transmission for - Type Floating Breakwaters”, Journal of Waterway Port Coastal and Ocean Engineering. Vol. 139, No. 1, January 1, 2013, ISSN 0733-950X / 2013 / 1-1-8.
    The graph in Figure 6 shows the results of the cells of the invention according to the two placement options with respect to the floating dock. White circles symbolize the outer junction cells; black circles, embedded cells (interior). In this graph it is observed that when using the embedded cell (interior) it is possible to reduce the impact force on the pile, in comparison with the use of the external cell.
