CN-224227829-U - Semicircular ecological cofferdam structure

Abstract

The semicircular ecological cofferdam structure provided by the utility model has the advantages that the semicircular structural design is utilized, the overall stability is improved, and the oyster shell gravel layer is filled in the structure, so that multiple ecological functions are realized. The semicircular structure is favorable for dispersing and guiding wave energy, compared with a structure with a clear standing or edge angle, wave reflection can be reduced, and the impact of hydrodynamic force on the cofferdam and the peripheral mud flat is reduced, so that erosion is effectively slowed down. The oyster shell not only enhances the structural stability, but also can further reduce wave impact, provide a buffer effect and reduce erosion to mangrove and peripheral beach. In addition, the oyster shell has natural water purification capability, can adsorb suspended particles and pollutants in water, and improves the ecological environment, so that the utility model improves the mangrove forest protection effect, realizes the recycling of the waste oyster shell, and provides a sustainable solution for coastal ecological restoration.

Description

Semicircular ecological cofferdam structure Technical Field The utility model relates to the field of ecological cofferdams, in particular to a semicircular ecological cofferdam structure. Background The mangrove forest is used as a unique wetland ecosystem in the coastal zone, and has important ecological functions of wind prevention, wave elimination, carbon fixation, carbon storage, water quality purification, biodiversity maintenance and the like. However, under the influence of coastal development, cultivation activities, natural erosion and the like, mangrove ecosystems often face problems of ecological environment fragmentation, coastline erosion, ecological function degradation and the like. In order to repair mangrove wetland or construct artificial mangrove habitat, the traditional cofferdam technology mostly adopts hard materials such as concrete, block stones and the like, but can quickly stabilize the shoreline, but can not clean water quality, and is difficult to reduce the impact of hydrodynamic force on cofferdam and peripheral beach, and is difficult to effectively slow down erosion. Disclosure of utility model First, the technical problem to be solved In order to solve the problems in the prior art, the utility model provides a semicircular ecological cofferdam structure. (II) technical scheme In order to achieve the above purpose, the main technical scheme adopted by the utility model comprises the following steps: The utility model provides a semicircular ecological cofferdam structure, includes cofferdam main part and cofferdam end cover, the hollow cavity of open-ended has been seted up for one end to the cofferdam main part, just fill in the cofferdam main part cavity has permeable material, the cofferdam end cover is installed the opening part of cofferdam main part. Preferably, the cofferdam main body is in a semi-cylindrical structure, and the cofferdam end cover is in a semi-circular shape. Preferably, the cofferdam main body is in a quadrangular frustum structure, and the cofferdam end cover is arranged at the top of the cofferdam main body. Preferably, perforations are uniformly distributed on the surface of the cofferdam main body and the cofferdam end cover. Preferably, the cofferdam end cover is fixed on the cofferdam main body through bolts. Preferably, the water permeable material is oyster. (III) beneficial effects The utility model has the beneficial effects that the overall stability is improved by utilizing the semicircular structure design, and the multiple ecological functions are realized by internally filling the oyster shell stone layer. The semicircular structure is favorable for dispersing and guiding wave energy, compared with a structure with a clear standing or edge angle, wave reflection can be reduced, and the impact of hydrodynamic force on the cofferdam and the peripheral mud flat is reduced, so that erosion is effectively slowed down. The oyster shell not only enhances the structural stability, but also can further reduce wave impact, provide a buffer effect and reduce erosion to mangrove and peripheral beach. In addition, the oyster shell has natural water purification capability, can adsorb suspended particles and pollutants in water, and improves the ecological environment, so that the utility model improves the mangrove forest protection effect, realizes the recycling of the waste oyster shell, and provides a sustainable solution for coastal ecological restoration.
