Description

Technical Field

[0001] The invention relates to the technical field of shock absorption of prefabricated concrete structures, and in particular to a wave energy dissipation mechanism, a prefabricated concrete structure and a wave-breaking wall. Background Art

[0002] Waves are the fluctuations on the water surface formed by the wind in the ocean. They have strong energy and can cause damage to buildings on the coast. In order to prevent wave invasion and form sheltered waters, coastal breakwaters have become necessary hydraulic structures. They are located on the periphery of the sea area and are an important part of the sea area. In coastal protection projects, wave energy dissipation concrete prefabricated structure technology came into being, and its development path mainly revolves around improving the durability, stability and energy dissipation efficiency of protective structures. Early technologies mainly focused on the physical protection capabilities of structures. With the advancement of technology, attention has begun to be paid to the ecological compatibility and environmental friendliness of structures, as well as innovative applications of materials, such as the use of recycled concrete and ultra-high performance concrete.

[0003] At present, the technology of prefabricated wave energy dissipation concrete structures has developed to include a variety of structural forms, such as high-pile docks, sheet pile docks, and pile-based open-type breakwaters. These structures mainly bear horizontal loads, including earthquakes, ship impact loads, wave effects, etc. In terms of seismic performance, the research on prefabricated high-pile docks is relatively concentrated, while the research on the seismic performance of sheet pile docks and pile-based open-type breakwaters is relatively small. In addition, in order to improve the energy dissipation effect of the structure, researchers have developed new sheet pile structural forms, such as unloading sheet pile docks, curtain-type sheet pile docks, steel pipe sheet pile docks, etc., to improve the berthing capacity of sheet pile docks by reducing the soil pressure in front of the sheet piles or increasing the bending stiffness of the sheet piles. In terms of construction technology, the development of the assembly and scheduling method of all prefabricated components makes the transportation and installation of prefabricated parts more accurate and efficient.

[0004] Although the technology of prefabricated concrete structures for wave energy dissipation has made some progress, there are still some shortcomings. The existing coastal breakwaters mainly use prefabricated concrete structures for prevention and control. Although they can achieve the function of coastal protection, they are easily damaged by long-term waves in the actual protection process, which affects their service life. Summary of the invention
