In other embodiments, connecting truss 400 may be fixedly attached to first high pile 120 and second high pile 320 by gluing or other connecting means.

Referring to fig. 10, in one embodiment, at least two connecting ropes 500 are provided on the outer wall of the wave-breaking net 200, wherein at least one of the connecting ropes 500 can be tied to the upper end of the first high pile 120, and at least another connecting rope 500 can be tied to the upper end of the second high pile 320. The wave dissipation net 200 is effectively fixed on the first high pile 120 and the second high pile 320 by arranging the connecting ropes 500, and the stability of installation of the wave dissipation net 200 is improved.

Specifically, the outer wall of the wave dissipating net 200 is provided with a hook 210, one end of the connecting rope 500 is tied to the hook 210, and the other end is tied to the first high pile 120 or the second high pile 320. Further, integrated into one piece has trip 210 on the outer wall of unrestrained net 200 that disappears, and it is fixed to be convenient for connect the connection of rope 500 through setting up trip 210, guarantees to connect the stability that rope 500 set up on unrestrained net 200 that disappears.

In other embodiments, the connecting lines 500 may also be tied directly to the connecting truss 400. Or the wave dissipating net 200 may be fixed to the connection truss 400 or the first protective assembly 100 or the second protective assembly 300 by other methods as long as the fixed installation of the wave dissipating net 200 can be achieved.

In one embodiment, the wave-breaking net 200 includes at least two wave-breaking layers 220, and each wave-breaking layer 220 is stacked and spaced apart in a vertical direction. Because the sea waves enter the mudflat 20 through the wave dissipation net 200, the wave dissipation layers 220 are stacked, so that the sea waves can effectively pass through the wave dissipation net 200, and the overlarge resistance of the wave dissipation net 200 to the sea waves is avoided.

In one embodiment, the wave dissipating net 200 is a water permeable honeycomb net. Specifically, the wave dissipation layer 220 is a water-permeable honeycomb net structure. In other embodiments, the wave-breaking net 200 may be other net structures as long as it can reduce the waves and weaken the water flow.

Referring to fig. 4 and 5 again, in an embodiment, a rockfill 600 is disposed on a side of the second protective assembly 300 opposite to the first protective assembly 100, and a height of the rockfill 600 is lower than a height of the second water blocking structure. Specifically, the rockfill 600 is piled on the lower end of the second low pile 330. The rockfill 600 is formed by riprapping the second protection component 300 at a side opposite to the first protection component 100, and the rockfill 600 is utilized to facilitate the stability of the second protection component 300 arranged on the seabed and prevent the second protection component 300 from toppling over. In other embodiments, the rockfill 600 may also be omitted. A support rod may be disposed on a side of the second protection component 300 opposite to the first protection component 100, one end of the support rod is disposed on the second protection component 300, and the other end is disposed at an interval from the second protection component 300 and abuts against the seabed.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.

In the description of the present invention, it is to be understood that the terms "central," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," "circumferential," and the like are used in the orientations and positional relationships indicated in the drawings for convenience in describing the invention and to simplify the description, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and are not to be considered limiting of the invention.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

In the present invention, unless otherwise expressly stated or limited, the first feature "on" or "under" the second feature may be directly contacting the first and second features or indirectly contacting the first and second features through an intermediate. Also, a first feature "on," "over," and "above" a second feature may be directly or diagonally above the second feature, or may simply indicate that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature may be directly under or obliquely under the first feature, or may simply mean that the first feature is at a lesser elevation than the second feature.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and the like as used herein are for illustrative purposes only and do not denote a unique embodiment.
