Abstract

The invention discloses a combined-type submerged breakwater structure. The combined-type submerged breakwater structure comprises a rigid submerged breakwater wave-blocking structure and a flexible plant wave-dissipating structure which are arranged side by side, and thus has a good wave dissipating effect; the rigid submerged breakwater wave-blocking structure is designed based on the Bragg resonance principle and has obvious wave preventing and bank protection effects; the flexible plant wave-dissipating structure adopts emergent flexible aquatic plants to dissipate waves, thus the water body environment can be significantly improved, and ecological benefits are maintained; and meanwhile, the flexible plant wave-dissipating structure is of a concrete frame structure and can form a goodsea water flow channel, and exchange of water bodies on the two sides and swimming of aquatic creatures are facilitated. The invention further discloses a manufacturing method of the combined-type submerged breakwater structure. After related data of a target sea area are collected, wave peak column body units are prefabricated and periodically arrayed, and then the flexible plant wave-dissipatingstructure is laid. The manufacturing method is low in cost, and construction is convenient; and practical value and ecological significance are both achieved.

Description

technical field [0001] The invention belongs to the technical field of port and coastal engineering, and in particular relates to a combined submerged embankment structure and a manufacturing method thereof. Background technique [0002] Coastal erosion causes a large amount of land loss, damage to coastal structures, and deterioration of the beach ecological environment, which has caused great harm to people's production, life, safety of life and property, and the ecological environment. The submerged embankment is a common hydraulic structure that protects the beach and promotes siltation. It has the functions of blocking the impact of waves and improving the scouring and silting conditions of the water area. Secondly, because it is an underwater structure, it does not affect the navigation of ships and maintains the beauty of the coast, so it is widely used in near-shore wave dissipation and siltation. [0003] The top surface and the upper part of the traditional riprap...
