Technical Problem

[0004]然而石笼内所投放石块占据了整个空间，缺乏足够的保证植物根系发育的条件，从而不利于水生植物生长，且石块之间间隙较大、分布不均，空隙中泥沙淤积量十分有限，导致石笼的促淤固沙和岸堤生态防护效果不甚明显，同时向石笼内投放大量石块使得工程物料成本激增

Benefits of technology

[0022]The beach protection net cage provided in this embodiment has a vegetation cavity set inside the first net cage, and a solidification layer is filled between the vegetation and the inner wall of the vegetation cavity. The solidification layer can prevent and dissipate waves and reduce the rise and overtopping of waves, thereby reducing the scouring of the beach by the reciprocating current. By opening a delivery port in the first net cage that communicates with the vegetation cavity, the vegetation can be put into the vegetation cavity to provide a growth environment for aquatic plants, so that the aquatic plants can grow normally and play an ecological protection role. It also promotes the deposition of sediment carried by the reciprocating current on the beach. It combines wave prevention and erosion resistance with sedimentation and sand fixation. It can not only effectively deposit the sediment carried by the reciprocating current on the beach, but also reduce the amount of stones used due to the effect of the vegetation and solidification layer materials, thus reducing the cost of engineering materials.

Abstract

The application discloses a beach protection net cage and a beach protection structure and belongs to the technical field of beach protection. The beach protection net cage is internally provided with a vegetation cavity, the first net cage is provided with a feeding opening communicated with the vegetation cavity, the vegetation body is accommodated in the vegetation cavity and is used for providing an environment for the growth of aquatic plants, the vegetation body is arranged in space with the inner side wall of the vegetation cavity, and the solidified layer is filled between the vegetation body and the inner side wall of the vegetation cavity. The wave resistance, the erosion resistance, the siltation promotion and the sand fixation are combined, the reciprocating flow can be effectively prevented from washing the beach, the silt carried by the reciprocating flow can be effectively deposited on the beach, and the use of a large number of stones can be avoided to reduce the engineering material cost. The beach protection structure is formed by splicing a plurality of beach protection net cages and has the functions of wave dissipation, siltation promotion, sand fixation and ecological beach protection.
