    The present invention relates to an attenuating element.
    Such an attenuating element can be used to attenuate the action of waves, such as on water control structures, such as dikes. In addition, the attenuating element according to the present invention can be used to attenuate sound waves, in which several attenuating elements form a sound attenuating wall or barrier. Other possibilities of attenuating wave energy can be achieved by means of attenuating elements, such as the removal of large amounts of water.
    In the state of the art, series of blocks that were placed against each other were used as attenuating elements that are used for dikes, in which the upper surfaces of these blocks were placed more or less attached. It was concluded that it is possible to achieve improvement if openings are provided on the upper side to which the water can be moved. As a result, the flow of water flowing into the dike is stopped and the dampening action increases.
    In the state of the art, however, this requires highly complex elements that are associated with proportionately high production costs.
    US 2002/0025231 describes an attenuator element set consisting of a series of attenuator elements with a common base part. This structure is very difficult to install, it certainly cannot be manipulated manually and does not provide a possibility of modifications in the shape of the body located below it, such as a dike body or another wall. Due to the common base part, there is no interaction with the rest of the dike.
    US 5,556,230 describes a coastal defense system that consists of a series of elements with narrow, enlarged parts that are pitted against each other in turns. Although this makes it possible to follow the shape of a dike body, it only achieves limited additional attenuation, if any. This structure is only suitable for preventing material erosion.
    All structures of this type have the disadvantage of being so heavy that they cannot be installed manually easily and, in addition, they are very difficult to produce with concrete material. More specifically, they require a very complicated mold and, as a result, it is not possible to produce them at high speed and on a large scale at relatively low cost.
    WO 03/076727 describes an ecological block that can be used on river banks and is equipped with cavities that must be filled with vegetation. The block is substantially rectangular and, in a first embodiment, is substantially flat on two opposite sides. In another variant (Fig. 6), one side is flat and the opposite side is equipped with an upper part and a base part. It is intended to place the flat side against a wall.
    It is an object of the present invention to provide an attenuating element by means of which waves, such as water waves or sound waves, can be optimally attenuated. In addition, it is the object of the present invention to be able to produce this attenuator element in a simple way, in which the latter has a relatively complex shape during operation while its installation is additionally facilitated, being possible manual installation.
    This object is struck by an attenuating element which has the characteristics of claim 1.
    According to the present invention, particularly effective attenuation is achieved by the fact that a neck part joins the upper part. As the cross-sectional area is smaller than the base part, the upper part is in fluid communication with the neck part and, as a result, the movement path of the medium to be attenuated is impaired due to the fact that a part, for example, of a wave against a dyke disappears in the neck part through the upper part.
    According to an advantageous embodiment of the present invention, all the attenuating elements are substantially identical and are substantially positioned in the same way, unlike the structure shown in US 5,556,230.
    Due to the use of separate attenuating elements, each with separate base parts, it is possible, by means of the present invention, to achieve interaction with a layer in a lower position.
    If the attenuating element according to the present invention is used, for example, on a dyke, several attenuating elements can be placed on a filter layer or gravel layer of a dyke. This filter layer allows the movement of water and also makes it possible to provide water removal. It is important, however, that this filter layer also stays in place under unfavorable circumstances, such as significant wave action.
    By means of the present invention, it is possible to control the amount of water flowing between adjacent upper parts. First, this can be controlled by determining the intermediate space between adjacent upper parts. The water that then flows along the upper part can be removed through a channel that is formed by a number of adjacent neck parts or through openings that are present between the base parts and flow forward into the layer of filter described above. By means of the present invention, it is possible to provide an ideal adaptation, such that, on the one hand, the ideal attenuation of the verified wave action can be achieved while, on the other hand, damage to the filter layer or other dike body foundation.
    A particularly simple structure can be achieved by constructing the attenuating element from two parts of attenuating elements. The attenuating element is preferably divided vertically, that is, each part of the attenuating element comprises an upper part, a neck part and a base part. The division is preferably in the form of a flat surface. In this way, a simple mold or form of work in combination with a press is sufficient, in which the upper side of the mold or form of work is the dividing plane. This makes it possible to quickly produce large quantities of parts of attenuating elements at relatively low costs. These half parts of attenuating elements can be fixed together, if desired, after production (or during production). For this purpose, it is possible to use, for example, connection methods. When installing a series of elements, however, it is also possible to place the parts of attenuating elements together without fixing each other.
    When made of concrete, the attenuating elements can be produced, for example, using presses. In this case, the moisture content and, therefore, the plasticity of the material to be used are selected in such a way that, on the one hand, ideal modeling can be conducted and, on the other hand, the residence time in the press mold can be kept as short as possible. In a variant, it is possible to arrange an auxiliary support made of relatively thin material in the press mold, in which the shape of this auxiliary support corresponds to that of the attenuating element and the press of the material of the attenuating element inside it. Plasticity is selected in such a way that it does not yet have sufficiently stable dimensions after the press. Using the auxiliary mold and removing it from the press, the material is given the opportunity to further harden the auxiliary mold until it is possible to remove the auxiliary mold. The production costs of these auxiliary molds are much lower than those associated with a longer press time.
    In a specific embodiment of the present invention, with a series of attenuating elements that are placed against each other, the intermediate space is achieved by the fact that the neck parts form a channel. In the case of a sloping dike on which the damping elements are placed, water will flow to the neck part through the upper part, ends in the channel formed by adjacent neck parts of adjacent damping elements and then flows back . On the one hand, this results in very effective attenuation, while, on the other hand, it achieves the removal of water. Preferably, this intermediate space is also present between the base parts of the attenuating elements. As a result, water can escape, for example, into the body of the dike. Preferably, said intermediate space is significantly less than the intermediate space between the upper parts. This avoids the occurrence of a vacuum effect when the attenuating elements are completely covered with water and the water recedes, which would result in the movement of material that is present between adjacent base parts, such as material similar to gravel.
    According to the present invention, each attenuating element is preferably composed of two parts of attenuating elements which can be placed against each other, in which, when two of these parts are placed against each other along their boundary surface, a upper part, a neck part and a base part.
    A corresponding mechanism can be used to attenuate the sound. In this case, it is still possible to supply the neck part with a sound attenuating material, such as fiber material.
    The upper part can have any conceivable shape. The upper part can be configured to influence the flow of fluid to be attenuated. This means that, by configuring the upper part in a certain way, the fluid flow can deflect, for example, in a certain direction or be divided into subflows.
    This way, when attenuating the sound, it can be advantageous to diffuse the sound through a pointed, spherical or similar shape from the top. This format can be optionally symmetrical. The lower side of the upper part, that is, the transition to the neck part can be configured to lock and / or retain sounds in the neck part. The present invention makes it possible easily to supply the upper part with a shape such that the fluid as well as the incident sound is deflected in a certain direction.
    The base is also preferably configured to be polygonal and, more specifically, square.
    More specifically, the corresponding polygon has curved, spherical and convex sides. This makes it possible to place adjacent elements at a slight angle against each other, so that curves in a dike body can be followed. In addition, the material will enter the intermediate space that is present between the adjacent bases, which results in further stabilization of the elements. Due to the square shape, for example, there is more space, compared to a hexagonal shape, for a convex part, which increases stability.
    If desired, the base parts can be configured to be tapered. The construction comprising parts of complex shaped elements according to the present invention makes it possible to produce complex shapes of the attenuating element at low cost.
    It is indicated that the cross-sectional area of the upper part of the attenuator element must be at least 10% smaller than the base part. Preferably, it is not more than 50% smaller than the cross-sectional area of the base part.
    The same applies to the upper part. When subsequently arranged in series, as in order to produce a dike body, the attenuating elements are preferably configured in such a way that the upper parts and, preferably, also the base parts rest against each other. This results in a particularly high degree of stability for this series of mitigating elements.
    According to a further advantageous embodiment of the present invention, the upper part is equipped with rounded tapered ends, in order to avoid damage when walking on the mentioned upper part and when walking or going over the dike bodies.
    Preferably, the upper parts, and more specifically when used in dike bodies, are configured in such a way that, when several attenuating elements are placed against each other, openings are present between adjacent upper parts through which water can flow into the neck part located below them. The size of these openings determines the "back pressure" encountered by water when a wave moves through a dike body. In addition, it is possible to influence the removal of water through these openings by the shape of the neck part. This bottleneck part can be configured to be larger or smaller than the top. In addition, it is possible to configure the neck part asymmetrically, in such a way that a larger cross-sectional area is available in one direction for the flow than in another.
    Preferably, the attenuator element is configured in such a way that there is as much rounding as possible, in order to achieve maximum strength as a result of the absence of sharp edges.
    The finish selection will depend on the application.
    When using a dike body, stability can increase after installing a series of attenuating elements, introducing a filler material, such as boulders. This will preferably be introduced between the base parts.
    The attenuating elements described above can be produced in any conceivable manner.
    A particularly appropriate method is to make them with concrete. One way of working in the form of the attenuator element to be produced is filled with concrete and, after the (slight) hardening of the attenuator element, it is removed.
    In addition, it is particularly possible to provide the top side with attenuating elements, that is, the parts facing towards the environment, with a layer that has ecological properties that are better than those of concrete that are generally used. As an example of this covering layer, mention is made of lava rock to which organisms can adhere.
    It is possible to provide this layer before pouring the concrete into the mold or work form. If desired, this mold or form of work can also be equipped with removable partitions, which results in different spaces that, on the one hand, can be filled with the ecologically best type of material and, on the other hand, with the concrete material conventionally used.
    In addition, it is possible to include environmentally polluting materials in the material from which the elements are produced. It is necessary to ensure that they cannot leak. Sulfur and fly ash are mentioned as examples. These materials can be incorporated, for example, into the concrete material used to make an element part.
    Due to this production method, it is possible to supply the attenuator element with any desired shape. In this way, the sides of the base part can be convex.
    By means of this production method, but also in any other conceivable way, base parts can be manufactured that are adapted for their use. In addition to the creation described above of space between the base parts in order to allow the removal of water for the dike body, it is also possible to configure the base parts in such a way that they match, resulting in precise positioning and, particularly, its fixation.
    As indicated above, it is possible to construct the attenuating elements from two optionally equal halves or in one part.
    In addition to the production method described above, it is also possible to achieve a fast production method through the pressure of concrete material. If the attenuator element is made in one piece, a mold is required that consists of two mutually disposable mold parts.
    The present invention also relates to a series of attenuating elements as described above, in which a channel is delimited by the neck parts.
    This series preferably comprises at least one hundred elements and, more specifically, at least one thousand elements. As indicated above, these attenuating elements are preferably substantially identical. According to an additional preferred embodiment, these attenuating elements in a series are oriented in substantially the same way.
    If the attenuating elements are used to attenuate sounds, they can be placed at an angle and, in a more external position, even vertically, in order to produce a vertical wall.
    Additional applications of the present invention are the removal of rainwater in tunnels or other places where large amounts of water can be collected.
    Depending on the application, various attenuating elements can be provided. In this way, they can, for example, be placed loosely against each other in dyke and similar applications. With other applications, but also by attenuating water, the attenuating elements can be bonded adhesive to each other and, for example, in sound attenuating applications, a sound attenuating material can be provided between the various attenuating elements in order to further increase the mitigating effect. This attenuating material can be an elastic type of glue, but it can also consist of pieces of filler that have attenuating properties.
    The present invention will be explained in more detail below with reference to examples of embodiments illustrated in the figures, in which: Fig. 1 diagrammatically shows a water control structure such as a dyke; Fig. 2 shows the attenuating elements used in the example of Fig. 1; Fig. 3 shows a further realization of the attenuating elements for attenuation of sounds; Fig. 4 shows a series of attenuating elements in Fig. 3; Fig. 5 shows the method of producing parts of attenuating elements; Fig. 6 shows a top view of some shapes from the top of the attenuating elements; Fig. 7 shows a top view of an example of the positioning of attenuating elements; and Fig. 8 shows a detail of the water control structure illustrated in Fig. 1. Fig. 1 shows a dike that is indicated by the reference number 1. The upper side of this dike is equipped with a reinforcement and / or protection which is indicated by reference number 2, in order to avoid material erosion. This reinforcement and / or protection consists of a series of attenuating elements 3 according to the present invention that are placed against each other. Fig. 2 shows an example of these attenuating elements. As can be seen, each attenuator element 3 consists of two parts of attenuator elements 4 and 5. For the sake of clarity, they were displayed at some distance from each other, but in practice the flat dividing planes 12 of each of the parts of attenuating elements will be placed against each other when building a series of attenuating elements, as illustrated in Fig. 1.
    Each attenuating element part consists of an upper part 6, neck part 7 and base part 8. Preferably, the base part is rectangular and, more specifically, square. As can be seen in Fig. 2, its shape is slightly convex. When the parts are placed against each other, it will be possible to pour material into the resulting intermediate space or the latter will be automatically filled with that material, for example, when sea water invades it. The neck part can be equipped with a rib 25 in order to increase its strength without significantly influencing the flow surface.
    The upper part has a polygonal shape with chamfers 10. The placement of four attenuating elements 3 according to the present invention against each other therefore results in an opening 11 towards the neck parts 7. As the neck parts have a cross-sectional area smaller than the upper parts, the upper parts delimit a continuous channel which is indicated by the reference digit 9. The cross-sectional area of the upper part is at least 10% and at most 50% smaller than the cross-sectional area of the base part. In practice, base 8 parts will be pitted against each other according to current regulations. An intermediate space may be present between adjacent base parts, depending on current regulations, in order to allow water to pass in the downward direction. The Dutch authorities, for example, stipulate that an intermediate space of at least 8 to 15% of the total length is present and that the maximum opening needs to be less than 5 cm. Of course, it is possible to deviate from this system. When placing the base parts against each other, there will always be enough space for the rear flow of water to the neck part 7 and then flow forward through the channel 9 which is formed due to the cross-sectional area smaller of the upper parts.
    It is also possible, however, to produce the attenuating elements in such a way that, when they are placed against each other, the upper parts will come to rest against each other. Placing the upper and base parts together when installing a series of elements results in a very stable structure. It is possible to provide the upper parts with a slight roundness, similar to the base parts. In addition, the base parts can taper from the bottom to the top, that is, if two attenuating elements are placed against each other, there is an intermediate space between the two that becomes smaller in the downward direction.
    The surface roughness of the damping elements can be selected based on needs. In the drawing, the neck parts are circular in Fig. 2. It is understood that they can also be oval, such that when the attenuating elements are placed against each other, the neck parts in each case delimit a conductor of passage that, in each case, has different dimensions of cross section in two directions.
    It was concluded that this realization results in a particularly high attenuation of water waves and, as a result, a dike body can be built relatively lightly, while still providing sufficient protection.
    Fig. 3 shows an additional variant of the attenuating element according to the present invention, which is generally indicated by reference number 13. Each attenuating element consists of parts of attenuating elements 14 and 15. Each part of attenuating element consists of a upper part 16, neck part 17 and base part 18. As in the previous embodiment, the cross-sectional area of the upper part 16 is smaller than the cross-sectional area of the base part 18. Unlike the previous variant, the upper 16 is not flat, but equipped with a pointed end 20.
    The neck portion and the adjacent attenuating elements together form a channel 19.
    Optionally, it is possible to provide the neck part with sound attenuating material, such as mineral wool or the like, by using the attenuating element as a sound barrier.
    Fig. 4 shows this use as a sound barrier with the base surface of the base parts being arranged substantially vertically. It was concluded that a particularly simple and resistant sound barrier can be produced in this way. In addition, it is possible to allow vegetation to grow over the aforementioned sound barrier. If desired, the upper parts can rest on top of each other.
    Fig. 5 illustrates an example of production of the attenuating element part 4, 5 and 14, 15, respectively. A mold or working form 26 is present, in which a mold cavity 27 is provided which corresponds to the shape of the attenuating element part to be produced. The bottom side comprises a plate corresponding to the subsequent plane 12.
    Fig. 6 shows a series of variants on the upper side of the upper parts 6 and 16, respectively.
    Fig. 7 shows a top view of the positioning of a series of attenuating elements as shown in Fig. 2. As can be seen, the convex shape of the base parts 8 facilitates the production of curvatures. By dividing each attenuating element, the weight of each part of the attenuating element can be kept relatively low. As an example, a weight of about 16 kg is mentioned. Weight savings of up to 40% can be achieved.
    Although this is not shown in Fig. 7, the attenuating elements 3 shown in each case consist of two parts of attenuating elements 4 and 5, as clearly shown in Fig. 2. It is also possible, however, to produce the attenuating elements in one part .
    The first tests showed that, with respect to a "smooth" slope, significant attenuation can be achieved, which means that the waves reach a shorter distance or move at a lower height through the dike body. The consequence of this is that, for the same expected wave action, a lower dike body is sufficient. It is therefore possible to make the existing dikes resistant to higher waves by installing the attenuating elements described above.
    Fig. 8 shows a series of adjacent attenuating elements 3 which are installed on the dike 1. This dike 1 consists of a foundation 31 of any material of the prior art and a filter layer 32 disposed on it. This filter layer may consist of gravel, such as gravel that is 5 to 6 cm in diameter. In addition, it is possible to create the filter layer 32 as a number of filter layers, in each case, of different sizes of stones or gravel. In addition, geotextile fabric may be present.
    In principle, the filter layer is porous and the different water flows are indicated by different arrows. The gravel layer is subjected to water pressure caused by the action of the waves. The neck layer serves to stabilize the dike body and the attenuating elements 3 illustrated herein serve to secure the filter layer.
    The figures clearly show that the amount of water that moves between the upper parts is partially removed from the conductors between the neck parts, partially disappears in the gravel layer and is removed by means of the latter. It is important, on the one hand, that there is a flow between the neck part and the gravel layer, but on the other hand, it is important that this flow does not become excessively large, in order to cause the gravel layer to lose the lift resistance for the damping elements and become unstable. By adapting the opening surface at the top, the dimensions of the neck part and the opening between the base parts adjacent to each other, these flows can be directed precisely to the maximum wave action to be expected.
    It will be understood that the upper part, the base part and the neck part can have any other shape. What is important is that a medium can pass from the upper part to the neck part and, for this purpose, the upper part has a smaller cross-sectional area than the base part. The neck part, in turn, has a significantly smaller cross-sectional area than the upper part, in order to form the channel described above.
    In addition, it will be understood that the attenuator element has many applications. In the specification above, all this was illustrated with reference to the side of a dike body over which water is present. However, it is also possible to install these attenuating elements on the other side of the dike body and, as a result, damage to the dike can be avoided by means of piping or eddies. Upon reading the above specification, technicians in the subject will immediately be able to imagine variants that are obvious and covered by the scope of the attached claims.
