As shown in fig. 1 to 2, a first embodiment of the present utility model is: coastal zone sediment erosion protection structure 10 comprises: the plurality of buffering piles 11 are distributed along the coastline for buffering wave energy of the waves, and the distribution line of the plurality of buffering piles 11 is parallel to the land coastline and can be generally arranged in a broken wave band, namely, the area with the greatest action intensity of the waves on the coast. Therefore, the balance of wave buffering distance of the coastline is ensured, and the condition that the wave erosion degree of the coastline is different is avoided. The section of the buffer pile 11 is in a water drop shape, the tip 111 of the water drop-shaped buffer pile 11 faces to the wave direction so as to separate the wave impact force, so that the wave energy is buffered, and meanwhile, the wave energy can be split, so that sediment carried by the wave is drained and accumulated to the rear of the buffer pile 11. The cover plate 12 is commonly supported above the plurality of buffer piles 11, and the cover plate 12 can guide waves to reversely move, so that the follow-up waves are reversely impacted, and the effect of buffering the wave impact is further achieved. The cover plate 12 should have a length to cover the upper end surfaces of all the bumper posts 11. The buffer pile 11 part is located the top of sea level, has not only guaranteed the stability of the fixed knot of buffer pile 11 like this, can also cushion the wave of different sea level, and application scope is wider.
In the first embodiment, the cross-sectional area of the bottom of the buffer pile 11 is larger than the cross-sectional area of the upper portion of the buffer pile 11, so that the tip 111 facing the wave breaking direction forms an inclined edge 112, the buffer stroke of the waves can be increased through the inclined edge 112, the impact force of the waves is gradually reduced, and finally, retarded diversion is performed, so that sediment buffering is facilitated, and ecological restoration of a coastline is performed. In addition, by increasing the buffering stroke to the waves, the impact force suffered by the buffering pile 11 can be reduced, and the structural stability of the buffering pile 11 is ensured.
Specifically, the cross-sectional area of the bottom of the bumper post 11 is 3 to 4 times that of the upper portion of the bumper post 11, so that the inclination angle of the inclined edge 112 can be defined, and the structure of the bumper post 11 is stabilized while the bumper is cushioned. The bottom edges of two adjacent buffer piles 11 are contacted with each other, so that the diverted waves can be further buffered through smaller flow passage limitation, and the sediment retention rate is improved.
As a specific embodiment, the height range from the upper end surface of the buffer pile 11 to the sea level is 1m or more and 1.5m or less, and such height limitation ensures the reverse wave drainage effect while improving the application range to the sea level.
As a specific embodiment, the cover plate 12 is made of reinforced concrete, and is stable in structure and not easy to erode by sea waves.
As a specific embodiment, the cover plate 12 has an inclined surface 121, the inclined surface 121 faces the wave traveling direction obliquely, and the included angle between the inclined surface 121 and the horizontal plane is 30 degrees, which helps to increase the dissipation effect of wave energy and has an interception effect on the returned sediment, thereby promoting the sediment to be deposited between the buffer pile 11 and the land (coastline).
As a specific embodiment, the buffer pile 11 is anchored to the coastal base by using steel bars, the structure is stronger, and the depth of the anchored lower end is 2-3 times of the scouring depth. The flushing depth referred to in this application refers to the depth at which the buffer pile 11 is located below sea level and between the coastal bases, and generally refers to the depth between the below sea level and the coastal bases in a general case (normal water level).
Fig. 3 shows a second embodiment of the present utility model, a coastal zone sediment erosion shield structure 10a, which differs from the first embodiment in that: the cushion pile comprises two mutually-intersected X-shaped supporting rods 13a, and the cross section of each supporting rod 13a is in a water drop shape. The two support rods 13a are supported in common below the cover plate 12 a. The included angle between the supporting rod 13a and the horizontal plane is 50-70 degrees. The support bar 13a is inserted into the coast base to a depth greater than the flush depth. The cover plate 12a extends in the horizontal direction. This second embodiment can increase the buffer density against waves and the blocking capability against sediment in the returning waves by forming a buffer pile 11 by intersecting two support rods.
The coastal zone sediment erosion protection structure 10 has the functions of reducing wave energy and intercepting sediment, protects the coastal zone from wave erosion by utilizing natural action, does not influence coastal sediment transport of the coastal zone during operation, and has small influence on an ecological system.
That is, a set of parallel shoreline coastal zone sediment erosion protective structures 10 are provided at a distance from the shoreline. When waves impact the structures, most of wave energy is dissipated, and scouring of the waves to the sediment on the post-construction repair coast can be reduced. When waves pass through the mechanisms, as wave energy is sharply reduced, sediment is deposited behind the structure, and the deposited sediment is gradually transported to a shore line under the action of sea and phoenix, so that the shore line is restored.
The foregoing has shown and described the basic principles, principal features and advantages of the utility model. It will be appreciated by persons skilled in the art that the above embodiments are not intended to limit the utility model in any way, and that all technical solutions obtained by means of equivalent substitutions or equivalent transformations fall within the scope of the utility model.
