Description

Technical Field

[0001] The utility model relates to the technical field of coastal protection, in particular to a wave dissipation device. Background Art

[0002] The coastal zone is an area affected by the rise and fall of tides and the alternating scouring of waves. Its existence provides important beach protection, reduces damage to coastal areas caused by waves, wind and tides, and prevents coastal floods, waterlogging and other disasters. In addition, the coastal zone is an important biodiversity habitat, where vegetation, animals and marine life can find a safe habitat. However, due to human activities, the amount of sand coming from the land has decreased. Under the same wave and wind force, the coastal zone continues to degrade, resulting in threats to habitats and property safety.

[0003] In order to ensure the safety of the coastal living environment, measures such as raising and reinforcing embankments are usually adopted to make the height of the embankments higher than the maximum height of the waves formed on the shore. Hard measures are used to resist wave forces and protect the beaches. However, these measures often require a lot of manpower and material resources; at the same time, in order to prevent the bottom of the protective measures from being hollowed out by waves and becoming ineffective, the foundation depth is often large, which further increases the investment. However, the hard revetment used affects the water ecological environment. There are also ways to maintain the stability of the coastal zone by "building breakwaters + artificial sand replenishment", but the breakwaters are mostly extended from the coastline to the ocean, which not only has a high cost, but also artificially blocks the lateral sand transport along the coast, causing a certain impact on the balance of the ecosystem.

[0024] Example 1

[0025] Combined with Figure 1-5The present embodiment proposes a wave dissipation device, comprising a plurality of bases 10 arranged in parallel and in series, and a wave energy dissipation structure 20 located on the base 10; the wave energy dissipation structure 20 comprises a bottom plate 21, a shore-facing inclined plate 22 and a sea-facing inclined plate 23, the bottom plate 21, the shore-facing inclined plate 22 and the sea-facing inclined plate 23 forming a hollow triangular structure; the base 10 is plugged into the bottom plate 21; the slope of the shore-facing inclined plate 22 is not less than 1:2; the sea-facing inclined plate 23 is provided with saw teeth, and the slope of the sea-facing inclined plate 23 is not greater than 1:10.

[0026] When waves break, they generate huge energy, which will cause severe erosion on the beach, so the coast needs to be protected. In view of the technical problems of defects in existing coastal protection measures, the wave dissipation device of this embodiment has a simple structure and is easy to install. It can dissipate wave energy and promote siltation in the eroded beach area, thereby helping to restore the beach structure.

[0027] The wave dissipation device of this embodiment forms an integral coastal protection structure by continuously setting a base 10 and a wave energy dissipation structure 20. The base 10 is placed on the beach or buried in the beach to serve as a basic component. The wave energy dissipation structure 20 is a hollow triangular structure composed of a bottom plate 21, a shore-facing inclined plate 22 and a sea-facing inclined plate 23, which can achieve the function of dissipating wave energy.

[0028] Overall, the wave dissipation device of this embodiment can imitate the natural beach slope. In actual use, one or more wave dissipation devices can be set in the wave-breaking zone to dissipate the energy of the wave breaking, reduce the wave flow rate, and promote the sediment deposition. When the wave passes over the wave energy dissipation structure 20, the scouring of the beach by the wave can be reduced. When the wave flows back, the wave energy dissipation structure 20 can block the return water of the wave, reduce the wave return flow rate again, promote the sediment deposition on the back wave side of the device, and finally gradually restore the eroded beach.

[0029] Furthermore, the wave dissipation device of this embodiment has a simple structure, is easy to lay, and the structural parts can be prefabricated, so it has the characteristics of fast construction speed and material saving.

[0030] In this embodiment, the wave energy dissipation structure 20 is a hollow triangular structure, and the hollow structure can save costs. The shore-facing inclined plate 22 is a smooth slope with a slope of not less than 1:2, which is used to block the wave backflow water body and cause the silt to accumulate on the upstream side. It can be understood that the upstream in this article refers to the side close to the land.

[0031] The slope of the seaward inclined plate 23 of the wave energy dissipation structure 20 is not greater than 1:10, so as to simulate the natural beach slope. In addition, the seaward inclined plate 23 is provided with saw teeth, which can dissipate wave energy and reduce wave velocity by using the sawtooth surface, thereby reducing the scouring of the beach by waves.

[0032] In an alternative embodiment, both the base 10 and the wave energy dissipation structure 20 are concrete structures.

[0033] In some embodiments, a slope 11 is provided at the edge of the base 10, and the slope 11 has a slope ranging from 1:2 to 1:1. The setting of the slope 11 can facilitate the guidance of wave flow on the one hand, and on the other hand, can also facilitate the burial of the base 10 on the coast.

[0034] The wave energy dissipation structure 20 of this embodiment is arranged on the base 10. In one embodiment, a first protrusion 12 is arranged near the edge of the base 10, and adjacent first protrusions 12 on adjacent bases 10 are spliced ​​to form a protrusion, and a first matching hole 24 is arranged on the bottom plate 21, and the protrusion is plugged and matched with the first matching hole 24. In this way, a fixed connection between the wave energy dissipation structure 20 and the base 10 can be achieved, and since the protrusion is composed of adjacent first protrusions 12 on adjacent bases 10, the protrusion is plugged and matched with the first matching hole 24, so that the connection stability between adjacent bases 10 can be ensured.

[0035] In a further embodiment, the height of the first protrusion 12 may be selected to be 0.4-0.7 m, and 0.5 m may be selected for general engineering design.

[0036] And, in one embodiment, the projection area of ​​the first protrusion 12 located on the same base 10 toward the base 10 accounts for 1 / 4 to 1 / 3 of the area of ​​the base 10. In this embodiment, materials can be saved while ensuring the stability of the connection between the base 10 and the wave energy dissipation structure 20.

[0037] In a further embodiment, the first protrusion 12 is a semi-conical protrusion, the adjacent semi-conical protrusions on the adjacent bases 10 form a complete conical protrusion, the first matching hole 24 is a conical hole, and the conical protrusion is plugged and matched with the conical hole. In this embodiment, the conical protrusion presents a structure that is narrow at the top and large at the bottom, which helps to guide the conical protrusion to be inserted into the conical hole, and can also ensure the root strength of the conical protrusion.

[0038] In other embodiments, the bottom plate 21 is provided with a second protruding member 13, and the base 10 is provided with a matching half hole 25 near the edge, and the adjacent matching half holes 25 on the adjacent bases 10 form a matching full hole, and the second protruding member 13 is plugged and matched with the matching full hole. In this embodiment, the base 10 and the wave energy dissipation structure 20 can also be firmly combined.

[0039] In some embodiments, the bottom of the base 10 is provided with saw teeth, and the length of the saw teeth is not less than 0.3 m. The saw teeth can be inserted into the seabed, so that the device as a whole can meet the anti-scouring requirements through the setting of the saw teeth.

[0040] In some embodiments, a cavity 14 is provided on the base 10 to form a hollow structure, and the cavity 14 can be of any shape, thereby reducing the weight of the structure and saving materials. In a further embodiment, the projection area of ​​the hollow structure on the ground does not exceed 1 / 5 of the projection area of ​​the base 10 on the ground, thereby ensuring the structural strength.

[0041] In some implementations, when the wave dissipation device of this embodiment is laid, a geotextile 30 is laid at the bottom of the base 10, and the length of the geotextile 30 beyond the edge of the base 10 is not less than 1 m, thereby enhancing the overall anti-scouring ability of the device.

[0042] And, in some embodiments, when the wave dissipation device of this embodiment is laid, a cover plate 31 is provided on the base 10 located at the edge, and the cover plate 31 is used to close the wave energy dissipation structure 20, so as to maintain the integrity of the entire structure.

[0043] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creative design without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
