Description

Permeable module and multifunctional submerged dike and fish reef adopting same

Technical Field

The utility model belongs to the technical field of coastal engineering construction, concretely relates to empty formula module and adopt multipurpose submerged dike and fish reef of this module.

Background

The submerged dike is a commonly used protective structure in coast protection and beach improvement and reconstruction, and is also a widely and effectively applied protective means at present. The submerged dike breaks open sea waves before the dike, so that the scouring of the open sea waves to the beach is blocked and weakened, the silt-promoting and beach-protecting effect is achieved, and meanwhile, the submerged dike structure is usually placed below the water surface, so that the submerged dike has more obvious advantages in the aspects of coastal landscape and environment compared with a spur dike, a revetment and the like, and the harmful effects on the coastal natural landscape are avoided. At present, in engineering, the submerged dike is mostly of a solid dike body structure, and is of a bank protection structure formed by adopting a throwing or stacking mode and the like. With the vigorous development of coastal engineering, the demand for beach maintenance and coastal protection is increasing. The solid submerged dike has higher construction cost, so that a multipurpose submerged dike structure which can improve the submerged dike function, protect the natural landscape of the coast and maintain the ecological balance and stability of the ocean is urgently needed.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve the technical problem that exists among the known technology and provide a formula of passing through air type module and adopt the multipurpose submerged dike and the fish reef of this module, the submerged dike that adopts this formula of passing through air module not only can improve effectively and disappear unrestrained firm husky effect, still can provide the environment of perching for fish, protects the nature view on coast to a certain extent, adopts the fish reef that this module combination formed, can protect and maintain marine ecology's balance and stability.

The utility model discloses a solve the technical problem who exists among the well-known technique and take first technical scheme is: a permeable module adopts a right-angle wedge-shaped frame structure made of reinforced concrete and is provided with a bottom plate, a rear side square frame and a front pore plate, wherein a plurality of uniformly distributed pressure reducing holes are formed in the bottom plate, the rear side square frame is vertically fixed at the rear end of the bottom plate, and the front pore plate is obliquely arranged and connected between the front end of the bottom plate and the top of the rear side square frame.

The multifunctional submerged dike is provided with two rows of the hollow modules, and the two rows of the hollow modules are arranged in parallel.

And the hollow module is internally filled with stones.

The utility model discloses a solve the third technical scheme that technical problem that exists takes among the well-known technique and be: the fish reef adopting the hollow modules is formed by combining and placing the hollow modules.

And the hollow module is internally filled with stones.

The utility model has the advantages and positive effects that: the permeable module adopts a right-angle wedge-shaped frame structure with a small upper part and a large lower part, has good stability, simple structure and convenient installation, and can be widely applied to fish reefs, beach protection and silt promotion, channel improvement and coast protection structures. The submerged dike formed by combining and arranging the open type modules can weaken the impact wave force of sea waves on the coast, and the sand carrying capacity of the water body is reduced due to the weakening of the wave energy of the waves passing through the submerged dike, so that the silt carried by the water body passing through the submerged dike by the open sea can be deposited, the beach surface can be continuously raised, and the effects of beach protection and silt promotion are achieved; meanwhile, the fish culture system can also provide habitat for fishes; the natural landscape of the coast is not influenced because the submerged dike is positioned below the water surface, and the natural landscape of the coast is protected to a certain extent; and the stability of the submerged embankment structure is good. Submerged dike structures with different penetration rates can be formed by adjusting the internal included angle or the height of the module; according to the wave eliminating condition of the submerged dike, the arrangement and combination mode of the modules are adjusted, and a better wave eliminating effect can be achieved. Therefore, the submerged dike formed by the permeable modules can meet the requirements of wave dissipation and silt promotion, ensure the stability of the water area behind the dike, and simultaneously is beneficial to water quality exchange, prevents the diffusion of pollutants and prevents the water pollution. Meanwhile, the cavity with the open structure can be used as an egg laying habitat of some fishes, and offshore ecological balance protection and ecological diversity are facilitated.
