As shown in fig. 1 and 2, embodiments of the present invention provide an energy absorbing member 10. Specifically, the energy absorbing member 10 is formed with a plurality of first through holes 16 that penetrate the top surface 12 and the bottom surface 14 of the energy absorbing member 10. Also, a recess 18 may be formed at least one edge of the energy-absorbing member 10.
It should be understood herein that the top and bottom surfaces 12, 14 of the energy absorbing member 10 as described above refer to: during the actual laying of the energy-absorbing structure 10, the side surface exposed to the outside and in direct contact with storm surge is the top surface 12, while the side surface opposite the top surface 12 and in contact with the underlying layer of decking is the bottom surface 14. In other words, the first through-hole 16 penetrates the top surface 12 and the bottom surface 14 of the energy absorbing member 10 in the thickness direction of the energy absorbing member 10.
As for the concave portion 18, it is located at least one edge of the energy-absorbing member 10, that is, the concave portion 18 is recessed from the edge of the energy-absorbing member 10 toward the center of the energy-absorbing member 10, thereby forming a concave groove shape as shown in fig. 1, for example.
During use of the energy absorbing members 10, adjacent energy absorbing members 10 are spliced to one another to form the form of an energy absorbing assembly 100 such as that shown in fig. 3. It should be understood that the energy absorbing assembly 100 shown in fig. 3 is merely illustrative, and the area, direction of the lay, etc. of the energy absorbing assembly 100 may be adjusted according to the actual circumstances of a particular lay site, and the invention is not limited to any particular form.
Referring to fig. 1 in conjunction with fig. 3, when adjacent energy-absorbing members 10 are spliced together, the recesses 18 face each other to form the second through-hole 20. In this way, when a storm surge comes, the wave-preventing surface can be effectively formed by the second through holes 20 and with the aid of the first through holes 16, and the roughness of the wave surface can be increased, thereby eliminating the kinetic energy of the waves. Also, the first and second through- holes 16 and 20 in the structure of the present invention can interact with an incoming storm surge so that the energy absorbing member 10 is not washed away, thereby enabling the above-described energy absorbing action without fixation.
Further, during the specific use process, when a storm surge comes, the kinetic energy of the sea waves is eliminated mainly by the aid of the second through holes 20 and the first through holes 16, so that the energy absorption effect is realized; meanwhile, when the waves are drained in a wave-damping mode, the waves are drained mainly through the first through holes 16, and simultaneously drained in combination with a drainage channel formed by a gap between a limiting protrusion (to be described in detail below) and the bottom surface 14 of the energy absorbing member 10.

In this manner, adjacent energy-absorbing members 10 may be better spliced to one another during the laying process without substantial misalignment or misalignment to form the second through-holes 20. In the embodiment shown in fig. 1 and 3, adjacent recesses 18 form a shape such as a hexagon when they are spliced together; that is, each recess 18 includes three sides. And since the recesses 18 are symmetrical to each other, the hexagonal second through holes 20 are also formed in a regular shape.
It should be understood, however, that the shape and size of each recess 18 is not intended to be limiting, and that other suitable sizes and shapes are possible, as may be appropriate for a particular application, and the invention is not limited in this regard.
With continued reference to fig. 1 in conjunction with fig. 2, in one embodiment of the invention, the energy-absorbing member 10 may further include a third edge 26 and a fourth edge 28 connecting the first edge 22 and the second edge 24 and opposing each other.
Specifically, the third edge 26 may form a first overlapping groove 30 with the top surface 12 of the energy absorbing member 10. Similarly, the fourth edge 28 may form a second overlapping groove 32 together with the bottom surface 14 of the energy-absorbing member 10, and the first overlapping groove 30 and the second overlapping groove 32 may be disposed symmetrically with each other along the center line of the width direction W of the energy-absorbing member 10. That is, as shown in the embodiment of fig. 2, the third edge 26 cooperates with the top surface 12 of the energy absorbing member 10 to form a first overlapping slot 30 located on the upper right side in the left view of fig. 2. And the fourth edge 28 forms a second overlapping groove 32, which is located on the lower left side in the left view of fig. 2, together with the bottom surface 14 of the energy-absorbing member 10.

For each first through hole 16, a hexagonal shape may be provided. In this way, a honeycomb-like arrangement as shown in fig. 1 can be formed. It should be understood, of course, that the first through hole 16 may be provided in any other polygonal shape, even circular or oval, as the case may be, and the present invention is not limited thereto.

That is, the second through hole 20 formed by splicing may also have a shape such as a hexagon. In one embodiment, the first and second through holes 16 and 20 may be identical to each other in shape and size; while in other embodiments the shapes and sizes may be different from each other.
As can be seen from the above description, the shape, size and position of each of the first through hole 16 and the second through hole 20 formed by splicing can be set according to specific situations; and the shape, size and positional relationship between the first through-hole 16 and the second through-hole 20 may also be adjusted as the case may be, that is, they may be the same or different.
In one embodiment according to the present invention, as shown in fig. 2, a plurality of limit protrusions 34 may be formed on the bottom surface 14 of the energy-absorbing member 10. The number, position and shape of the limiting protrusions 34 are not intended to limit the present invention. Due to the arrangement of the limiting protrusions 34 on the bottom surface 14 of the energy absorbing member 10, the limiting protrusions 34 can effectively contact with the underlying pavement layer during actual use, thereby preventing the energy absorbing member 10 from being washed away by storm surge; and due to the presence of the stop bosses 34, the bottom surface 14 of the energy absorbing member 10 is spaced from the underlying layup, thereby forming a drainage channel therebetween for drainage of storm surge.
In one embodiment, the mass of the energy absorbing member 10 of the present invention may satisfy the following formula (i.e., at design time, the self mass of the energy absorbing member 10 should satisfy the side slope sea wave formula, which is related to the side slope elevation angle, the near shore water depth, and the design wave height):
