Description of the embodiments

The technical scheme of the utility model is further described in detail below with reference to the specific embodiments.

As shown in fig. 1 and 2, in the embodiment of the present utility model, an empty oyster reef block comprises a concrete outer ring 1, including a long side and a short side, wherein the long side is an offshore side and is a continuous structure, the short side is an offshore side, a plurality of groups of openings are formed on the short side, the top of the concrete outer ring 1 is arc-shaped, a plurality of groups of holes are formed on the surface of the concrete outer ring, and shell fillers 1b are placed in the holes; the oyster reef blocks 2 are arranged on the inner side of the concrete outer ring 1 in a plurality of groups, and comprise stone pile bamboo pile reef bodies 2b, wherein the stone pile bamboo pile reef bodies 2b comprise a plurality of groups of fixed columns and stones, the fixed columns are fixedly inserted into the beach, and a plurality of groups of stones are piled on the periphery of the fixed columns;

The concrete outer ring 1 is designed to be a hollow semicircular concrete block 1a, has the advantages of large block weight and high strength, can effectively resist storm surge, can keep good stability under the action of sea waves, achieves good wave-eliminating and flow-slowing effects, creates an inner side backwave flow-slowing area, and is internally provided with shell fillers 1b to further ensure the stability of the small reef body;

Meanwhile, by arranging the block-pile bamboo pile reef body 2b in the concrete outer ring 1, the impact of sea waves entering the inner side of the concrete outer ring 1 from the opening at the short side is reduced, the capability of resisting wind waves is improved, other biological growth is facilitated, rich food sources are provided for oysters, fishes and the like, and the biological diversity is improved.

As shown in fig. 2, in the embodiment of the present utility model, the shell filler 1b is oyster shell, the oyster shell is placed in a storage net bag, and the storage net bag is fixedly connected with the concrete outer ring 1 through a connection rope 1c, so as to reduce damage to the oyster shell reef body caused by tidal flat stormy waves.

As shown in fig. 2, in the embodiment of the present utility model, the connecting rope 1c is made of polyethylene, or other environment-friendly and corrosion-resistant ropes.

As shown in fig. 2, in the embodiment of the present utility model, the fixing column is a bamboo pile 2a, and a plurality of groups of communication holes are formed in the side surface of the bamboo pile 2a, and the communication holes are used for personnel to pour silt into the bamboo pile 2a, so that stability of the bamboo pile 2a in a beach is greatly improved, and the periphery of the bamboo pile 2a is piled up by block stones, so that stormy waves weakened by the concrete outer ring 1 can be effectively resisted.

In the embodiment of the utility model, as shown in fig. 1, a plurality of groups of oyster reef blocks 2 are annularly arranged at intervals along the inner part of the concrete outer ring 1, or the oyster reef blocks 2 are linearly arranged in the concrete outer ring 1 at intervals in an annular manner.

By integrating the above, in the utility model, by designing the concrete outer ring 1 and the oyster reef blocks 2, the concrete outer ring 1 forms a firm defense line on the outer side, wind wave action in an inner side area is greatly reduced by entering the concrete outer ring 1, meanwhile, the bamboo piles 2a are inserted into the inner side of the concrete outer ring 1, the bamboo piles 2a are piled and fixed by using the block stones, the block stone pile bamboo pile reef body 2b is formed, the stability of the bamboo piles 2a is further improved by using the block stone pile piling stabilization effect, and wind wave impact is reduced. In addition, the surface roughness of reef bodies such as net bag oyster shells, stone blocks and the like greatly increases the adhesion probability of the oyster, and various habitats are created by utilizing the concrete blocks 1a, the oyster shells, the stone blocks, the bamboo piles 2a and the like, so that the ecological floating type reef is beneficial to perching and breeding of other benthonic organisms, fishes and the like.

While the preferred embodiments of the present utility model have been described in detail, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present utility model within the knowledge of those skilled in the art.
