Abstract

The invention discloses a protection structure for an artificial island revetment. The protection structure comprises multiple parallel prefabricated cylinders and a cover plate for coving all the prefabricated cylinders in a sealed manner. A bottom plate is arranged on each prefabricated cylinder. The cylinder wall and the bottom plate of each prefabricated cylinder are formed through overall pouring. Every two adjacent prefabricated cylinders are connected together through a cast-in-place concrete structure equal to the prefabricated cylinders in height. The lower portion in each prefabricated cylinder is filled with sand. Barrier boards are pressed on the sand. Wave dissipating holes are formed in the side facing waves of the upper portion of each prefabricated cylinder. By the adoption of the protection structure for the artificial island revetment, the wave reflection, wave force and wave run-up of the structure can be reduced, the foundation stress is lowered, the anti-sliding stability of the structure is improved, the washout difficulty of waves to the foundation is increased, and the anti-washout stability of the structure is improved; transportation and construction are easy; and the protection structure is adaptive to coral reef foundations, capable of resisting the bad wave condition and effectively reducing the washout of the waves and suitable for artificial islands or atolls with the bad ocean environment and the complex geological conditions.

Description

technical field [0001] The invention relates to a building structure for port and coastal engineering, in particular to an artificial island revetment protection structure. Background technique [0002] Based on the needs of my country's distant sea development strategy, the construction of artificial islands (or islands and reefs) is an important direction for the future development of my country's port and coastal engineering. However, the unique harsh hydrological environment and complex geological conditions of the far sea make the far sea project face greater challenges than the nearshore project construction, and the related research is very scarce. [0003] Coral reefs are widely distributed in the far seas of my country. Coral reefs are rock-soil bodies formed by long-term geological processes after the death of coral groups. They are extremely valuable land resources in the ocean. [0004] At present, membrane bag sand is mostly used for revetment of artificial isl...
