Description

Technical Field

[0001] This utility model relates to the technical field of embankment revetment structures, and in particular to a revetment structure for wave dissipation on sloping embankments. Background Technology

[0002] In seawall engineering, sloping seawalls are widely used due to their strong adaptability and relatively convenient construction. However, traditional sloping seawall revetment structures often have the following defects: First, the slope is flat, and the waves consume less energy during the process of climbing up the slope, resulting in higher wave height and limited wave dissipation capacity. Long-term exposure to wind and waves can easily lead to problems such as slope damage and seepage in the embankment. Secondly, although it can break waves and reduce wave rise through special structures, its construction process is complex, requiring prefabrication of components and precise on-site installation, and the material and construction costs are high, which is not conducive to large-scale promotion and application.

[0003] Therefore, there is an urgent need for an efficient and economical facing structure solution.

[0004] In view of this, the inventors have specifically designed a protective structure for wave dissipation on sloping embankments, which leads to this invention. Utility Model Content

[0005] To solve the above problems, the technical solution of this utility model is as follows: A protective structure for wave dissipation on a sloping breakwater includes a sloping breakwater body, wherein the seaward side of the sloping breakwater body is provided with a geotextile layer, a crushed stone cushion layer, and a dry-laid stone revetment layer in sequence, wherein: The dry-laid stone slope protection layer comprises several dry-laid stone units, and a wave-dissipating zone is formed between adjacent dry-laid stone units; The wave-dissipating zone of the dry-laid stone slope protection layer is paved with wave-cutting stones; The bottom of the sloping embankment is equipped with a buried stone concrete foundation. The outer side of the buried stone concrete foundation is protected by riprap. The top of the sloping embankment is equipped with a embankment cap. Expansion joints are provided in both the buried stone concrete foundation and the top cap of the embankment.

[0006] Preferably, the surface of the dry-laid stone slope protection layer is provided with transverse concrete frames and longitudinal concrete frames spaced at intervals.

[0007] Preferably, the transverse concrete frame is installed every 3-5m, and the longitudinal concrete frame is installed every 4-6m.

[0008] Preferably, the wave-dissipating stone partitions are arranged on the dry-laid stone slope protection layer.

[0009] Preferably, the wave-dissipating stone is 0.1-0.3m higher than the dry-laid stone slope protection layer.

[0010] Preferably, the slope of the embankment body is 1:2, and it is formed by backfilling and compacting sandy soil.

[0011] Preferably, the geotextile layer is made of 300g / m² geotextile, the crushed stone cushion layer is 200mm thick, the dry-laid stone slope protection layer is 1000mm thick, and the dry-laid stone units are constructed vertically with their four sides tightly joined.

[0012] Preferably, the embedded stone concrete foundation and the embankment top cap are both constructed using C30 embedded stone concrete.

[0013] Preferably, the top elevation of the riprap toe protection is higher than that of the buried stone concrete foundation.

[0014] Preferably, the expansion joints of the buried stone concrete foundation and the top cap of the embankment are set every 6-10m, with a width of 1-2m, and are filled with asphalt-impregnated fir wood boards.

[0015] The beneficial effects of this utility model are as follows: This invention significantly increases the roughness of the slope surface through the dry-laid stone revetment layer and the roughening design of the wave-cutting stones in rows and blocks. The energy of the waves is fully consumed during the climbing process, effectively breaking the waves, reducing the wave rise, and reducing the impact of the waves on the seawall.

[0016] In addition, the vertically laid stone blocks with close proximity on all four sides provide a large contact surface and strong embedding effect. Combined with the grid-like C30 concrete frame, this significantly enhances the slope's resistance to sliding and overturning. At the same time, the double-layered toe protection of the embankment, consisting of a buried stone concrete foundation and a riprap toe protection, prevents the toe foundation from being hollowed out and avoids uneven settlement of the foundation.

[0017] In particular, the protective structure of this utility model does not require prefabricated components and directly adopts conventional processes such as dry masonry and casting, which simplifies the construction process and makes the materials readily available, thus reducing construction and material costs.

[0018] In summary, compared with traditional slope protection structures, the revetment structure in this utility model is simple, has significant wave dissipation and erosion resistance effects, and operates stably, making it worthy of reference and guidance for seawall reinforcement projects.

[0025] In addition, wave-damping stones 500 are laid in the wave-damping zone 420 of the dry-laid stone slope protection layer 400.

[0026] In this embodiment, wave-dissipating stones are arranged in alternating rows on the dry-laid stone slope protection layer 400 (multiple rows can be distributed), with each dry-laid stone unit 410 having its four sides close together, and the wave-dissipating stones being 0.3m higher than the upper surface of the dry-laid stone slope protection layer 400.

[0027] At the bottom of the sloping embankment body 100, there is a C30 buried stone concrete foundation 600, which is 1.5m wide and 2.5m high.

[0028] The toe of the embankment is located outside the buried stone concrete foundation 600, and a riprap is set to form a riprap toe 700. The top elevation of the riprap toe 700 is higher than that of the buried stone concrete foundation 600 by 1m, and the bottom width is 1.5m with a slope ratio of 1:1.5.
