Description

Technical Field

[0001] The present invention relates to the field of marine engineering technology, and in particular to a double-jointed component integrating wave dissipation, anti-collision and ecology and application thereof. Background Art

[0003] According to domestic and foreign literature searches, there are many types of wave-breaking structures, such as the X-shaped artificial surface wave-breaking block disclosed in Chinese patent application No. 201911192777.1, the triple-type wave-breaking block disclosed in Chinese patent application No. 200810153738.6, as well as traditional wave-breaking boards, twisting blocks and twisting king blocks, etc., but these structural forms do not have ecological functions.

[0004] There are also many anti-scour protection measures, such as artificial aquatic plant mats, floating curtains and silt-promoting boards, anti-scour mats, riprap, geotechnical plant mats, tetrahedrons, hexahedrons, etc., as well as the integration technology of these measures. For example, Chinese patent application No. 202010770368.1 discloses a semi-submersible layered anti-scour and silt-promoting device, which is a layered integration of anti-scour measures such as artificial aquatic plants and floating curtains and silt-promoting boards. However, these measures have weak wave-breaking functions, often lack ecological functions, and their stability on the seabed needs to be strengthened.

[0005] Therefore, it is of great significance to develop artificial structures that integrate ecological, wave-breaking and scour protection functions.

[0006] After searching, it was found that the Chinese utility model patent with the authorization announcement number CN211898178U discloses a concave hexagonal prism-shaped protective face block and protective face structure, including a hexagonal prism block, the opposite sides of the hexagonal prism block are respectively concave inward, the top surface of the hexagonal prism block is provided with a wave-breaking channel that runs through the bottom surface, and the front side of the hexagonal prism block is provided with a hole that runs through the back side, and the hole is connected to the wave-breaking channel. When several hexagonal prism blocks are installed on the dam protective face, the concave surfaces and the top and bottom surfaces of adjacent hexagonal prism blocks are arranged closely, so that there is a pressing force between adjacent hexagonal prism blocks and a protective face structure is formed. The wave-breaking channels and holes provided on the hexagonal prism blocks can not only reduce the wave force, but also provide a habitat for fish due to the low flow rate in the body and between adjacent bodies. Although this technology realizes the functions of ecology, wave breaking and scour protection, it is difficult to construct and cannot be directly cast. Otherwise, the gaps between these blocks are not only too large, but also too many, with fewer overlapping parts, which not only reduces the anti-scouring effect but also causes poor stability of the blocks.

[0036] The embodiment of the present invention is based on mechanical calculations in coastal dynamics and sediment movement mechanics, and numerical simulations of wave and current energy dissipation and deceleration. By conducting flume experiments on double-connected components of different configurations, the following double-connected components with peculiar configuration are obtained, which integrates ecological, wave-breaking and scour protection functions.

[0037] Reference Figure 1 As shown, a double-jointed component integrating wave dissipation, impact prevention and ecology provided by an embodiment of the present invention comprises a hollow pentahedron 1, a solid hexahedron 2, a hanging ring 4 and a flexible connector 3, wherein: the hollow pentahedron 1 is a triangular prism, a cylindrical cavity is opened inside the hollow pentahedron 1 along the height direction of the triangular prism, the cylindrical cavity is located at the center of the hollow pentahedron 1, the cylindrical cavity is a non-penetrating cavity, the top and bottom of the hollow pentahedron 1 are at an equal distance from the end of the cylindrical cavity, and the triangular prism is provided at a height direction of the triangular prism. Holes 5 are respectively provided between the top surface of the cylinder and the top of the cylindrical cavity, between the bottom surface of the triangular prism and the bottom end of the cylindrical cavity, and between the cylindrical cavity and the three side surfaces of the triangular prism; a hanging ring 4 is provided at the top of the hollow pentahedron 1; the solid hexahedron 2 includes an upper part and a lower part, the upper part is a prism surrounded by a plurality of equilateral triangles, the upper part is symmetrical to the lower part, and the two have the same size; one end of the flexible connector 3 is connected to the bottom of the hollow pentahedron 1, and the other end is connected to the top of the solid hexahedron 2.

[0038] In the embodiment of the present invention, the hollow pentahedron 1 can reduce the specific gravity of the block and increase the sedimentation resistance, and the free sinking speed is low during dumping; after touching the bottom, multiple streams of fluid in different directions collide with each other, increasing energy consumption, reducing the invasive power and flow rate of the incoming flow, and forming a habitat for underwater organisms; while the solid hexahedron 2 has a higher specific gravity and a faster free sinking speed, ensuring that the solid hexahedron 2 of the double-connected component touches the bottom before the hollow pentahedron 1, and the hollow pentahedron 1 arrives at the seabed surface later, and the hollow pentahedron 1 falls downstream of the solid hexahedron 2 due to the push of the wave current during the falling process, that is, the solid hexahedron 2 is located upstream of the hollow pentahedron 1. When the upper layer is dumped, the solid hexahedron 2 and the hollow pentahedron 1 are staggered and laid on the solid hexahedron 2 and hollow pentahedron 1 of the lower layer, and the solid hexahedron 2 is mostly pressed on the lower layer, while the hollow pentahedron 1 of the upper layer is pulled by the solid hexahedron 2 pressed below to prevent it from being washed away by the wave current. This staggered and intertwined structure can automatically realize a stable structure with upper and lower layers staggered with each other, while the double-connected components formed by other shapes are not easy to form this stable structure.

[0039] In the embodiment of the present invention, through the mutual cooperation between the hollow pentahedron 1, the solid hexahedron 2 and other structures, a plurality of double-connected components are coupled with each other and cross-rolled to form a multi-angular, multi-porous accumulation body, and gaps are formed between the accumulation bodies. The accumulation body constitutes a resistance and energy dissipation unit for the incoming waves, which can effectively eliminate most of the energy of the external wave flow, significantly reduce the incoming wave velocity and reduce the wave climb and overtopping amount.

[0040] The embodiment of the present invention forms a multi-angular and multi-porous accumulation body through multiple double-connected components, which significantly improves the overall structural stability and enhances the anti-tilting and anti-sliding stability against waves and currents; moreover, since the accumulation body can significantly reduce the internal flow velocity and weaken the scouring ability of waves and currents, it effectively promotes siltation and plays a protective role in promoting siltation and preventing scouring for the foundation of marine engineering.

[0041] The embodiment of the present invention can significantly reduce the wave intensity inside and around the block, and the double-connected components are crossed and coupled with each other, and are not easily moved by waves and currents, so that aquatic organisms can live inside the hollow pentahedron 1 and near the double-connected component block, thereby acting as a fish reef.

[0042] In some embodiments, the bottom surface and the top surface of the hollow pentahedron 1 are parallel, the bottom surface and the top surface have the same shape, and the bottom surface and the top surface are congruent isosceles triangles; preferably, one of the angles of the bottom surface of the hollow pentahedron 1 is 30°, and the lengths of the sides of the bottom surface are 0.4m, 0.9m and 1.8m respectively; the height of the triangular prism is 1.2m.

[0043] In some embodiments, the axis of the cylindrical cavity is perpendicular to the two parallel surfaces of the hollow pentahedron 1. Preferably, the diameter of the cylindrical cavity is 0.2 m and the height is 1.4 m, which plays the role of energy dissipation, slow flow, and providing a habitat for aquatic organisms. Holes are opened from the two end faces of the cylindrical cavity to the two parallel surfaces of the triangular prism, and holes are opened from the three side faces of the triangular prism to the cylindrical cavity, forming a five-hole structure connected inside and outside. Preferably, the aperture of the hole 5 is 0.2 m, and the hole 5 achieves the role of energy dissipation, slow flow, and providing a habitat for aquatic organisms.

[0044] In some embodiments, the solid hexahedron 2 is a solid body made of concrete or reinforced concrete, and the upper and lower bases of the solid hexahedron 2 are prisms or streamlined ellipsoids surrounded by three equilateral triangles. Preferably, the height of the upper and lower parts of the solid hexahedron is 0.3m, and the vertex angle of the solid hexahedron 2 is equal to 60°. This arrangement ensures stability under the action of waves and currents during storm surges.

[0045] In some embodiments, the flexible connector 3 is made of an ultra-high molecular organic material that is corrosion-resistant, UV-resistant, and salt-resistant. For example, the flexible connector 3 is made of a cable; the diameter of the flexible connector 3 is 0.01 to 0.03 m and the length is 1 m to 5 m, thereby achieving the connection between the hollow pentahedron 1 and the solid hexahedron 2.

[0046] In some embodiments, the hanging ring 4 is made of an ultra-high molecular organic nylon material that is corrosion-resistant, UV-resistant, and salt-resistant. The diameter of the hanging ring 4 is 0.03 to 0.06 m and the length is 0.1 m to 0.3 m, so that the double-connected component can be hung on the hook of the crane to achieve the release of the double-connected component.

[0047] Based on the same inventive concept, another embodiment of the present invention provides an application of the above-mentioned double-connected components integrating wave-breaking, impact-proofing and ecology, which includes: throwing a plurality of the above-mentioned double-connected components around the marine engineering foundation, coupling with each other to form a multi-angular and porous accumulation body.

[0048] In some embodiments, the minimum weight of the hollow pentahedron 1 of the double-connected component for anti-slip and anti-tilting is determined according to the maximum wave force and moment, and the weight of the hollow pentahedron 1 is greater than the minimum weight. For example, a hollow pentahedron block with a weight corresponding to a design safety factor of 1.5 is used as the main wave-breaking component, that is, the weight of the hollow pentahedron is 1.5 times the minimum weight. Specifically, according to the particle starting shear stress τ under the action of the extreme wave current 0m and the specific gravity of the hollow pentahedron 1γ s , the corresponding starting conditions: Get particle size Therefore, the equivalent particle size of the hollow pentahedron 1 is Thus, the minimum weight of the hollow pentahedron 1 for anti-slip and anti-tilting is obtained.

[0049] On the water-facing side of the seawall, solid hexahedrons 2 are laid on the lower layer (the gaps between the hollow pentahedrons 1), and after the flexible connectors are extended, the hollow pentahedrons 1 are laid tightly and staggered on the upper layer (above the solid hexahedrons 2). Multiple hollow pentahedrons 1 are coupled with each other to form an accumulation of multiple edges and holes, which constitute a resistance and energy dissipation unit for incoming waves and currents, and play a role in reducing flow velocity, wave height and overtopping.

[0050] In the above embodiment, for the upper block, in addition to the wave and current force, the drag force of the flexible connector pressing on the solid hexahedron 2 of the lower layer is added, making it difficult to start the upper block. The solid hexahedron 2 is pressed down by the hollow hexahedron 1 of the upper layer, so there is generally no starting problem after the construction is completed.

[0051] In some embodiments, the minimum starting weight of the hollow pentahedron 1 is determined according to the maximum bottom bed shear stress under the combined action of waves and currents (minimum starting weight = maximum bottom bed shear stress × bottom area of ​​the hollow pentahedron / friction coefficient of the local bottom bed), and the weight of the hollow pentahedron 1 is greater than the minimum starting weight, such as the weight of the hollow pentahedron block corresponding to the design safety factor of 1.3;

[0052] The hanging ring 4 of the double-connected component is hung on the hook of the crane, and the hook is moved to a designated position around the foundation of marine engineering buildings such as piles, risers, and wind power foundations with the help of a positioning system, and the double-connected component on the hook is released, and a mutually coupled accumulation body is formed by a dumping method. Specifically, since the specific gravity of the solid hexahedron 2 is greater than that of the hollow pentahedron 1, and the water-blocking area of ​​the solid hexahedron 2 is smaller than that of the hollow pentahedron 1, the falling speed of the solid hexahedron 2 in the ocean is greater than that of the hollow pentahedron 1, until the cable is tightened and the falling speeds of the two are equal. Therefore, the solid hexahedron 2 will reach the seabed surface first, and the hollow pentahedron 1 will reach the seabed surface later. However, during the falling process, the hollow pentahedron 1 will land downstream of the solid hexahedron 2 due to the push of the wave current, which will press the first layer of cable and the solid hexahedron 2. The multiple layers of tight filling will form a cross-connection and cross-rolling of the lower double-connected components, which will significantly improve the stability of the overall structure; they will couple with each other to form a multi-angular and hollow accumulation body, which will constitute a resistance and energy dissipation unit for the incoming wave current, and play a role in reducing the flow velocity and reducing scouring.

[0053] In some embodiments, the minimum weight of the double-joined member for anti-slip and anti-tilting is determined according to the maximum wave force and moment, and the calculation method is similar to the method for determining the minimum weight of the hollow pentahedron 1 for anti-slip and anti-tilting of the double-joined member. The weight of the double-joined member is greater than the minimum weight of the double-joined member for anti-slip and anti-tilting, such as the double-joined member block with a weight corresponding to a design safety factor of 1.3;

[0054] The hanging ring 4 of the double-connected component is hung on the hook of the crane, and the hook is moved to a designated position around the foundation of the marine engineering building, and the double-connected component on the hook is released. The double-connected component is tightly built into a mutually coupled accumulation body with multiple edges and holes by using the dumping method, which plays a role in reducing the flow velocity and wave intensity. The accumulation body is used to construct an ideal flow field for aquatic organisms, which serves as a fishing reef that is conducive to the growth of aquatic organisms.

[0055] The above-mentioned embodiments of the present invention can realize the functions of wave elimination, scour protection and fish reef construction at the same time, and can significantly improve the stability of the block.

[0056] In a specific embodiment, a double-connected component for promoting siltation and preventing erosion around a wind power foundation with a pile diameter of 8m is provided, which mainly includes a hollow pentahedron 1, a flexible connector 3, a solid hexahedron 2, and a hanging ring 4. The bottom and top surfaces of the hollow pentahedron 1 are parallel; the bottom and top surfaces are congruent isosceles triangles; a cylindrical cavity is hollowed out in the body, and the axis of the cylindrical cavity is perpendicular to the two parallel surfaces; small holes are opened from the two end surfaces of the cylindrical cavity to the two parallel surfaces of the triangular prism, and small holes are opened from the three side surfaces of the triangular prism to the cylindrical cavity, forming a five-hole structure connected inside and outside. The upper part of the solid hexahedron 2 is a prism surrounded by multiple isosceles triangles, with a vertex angle equal to 45°, and the upper part is symmetrical with the lower part. The hollow pentahedron 1 is connected to the solid hexahedron 2 with a flexible connector 3, and the hanging ring 4 is set on the top of the hollow pentahedron 1.

[0057] The hollow pentahedron 1 is made of concrete, the side lengths of the bottom and top surfaces are 0.5 m, an angle is equal to 45°, and the length of the prism is 1.2 m.

[0058] The solid hexahedron 2 is a solid body made of concrete, the upper part of which is a prism surrounded by three isosceles triangles, the top angle of which is 60°, the upper part is symmetrical to the lower part, and the height of both is 0.3 m.

[0059] The flexible connecting member 3 is a cable made of HDPE material with a diameter of 0.02 m and a length of 3 m.

[0060] The hanging ring 4 is made of HDPE material, with a diameter of 0.05m and a length of 0.2m.

[0061] The hole 5 is arranged in the hollow pentahedron 1, and the hole diameter is 0.35m. The diameter of the inner hollow cylindrical cavity is 0.35m and the length is 0.9m.

[0062] The implementation process of the double-jointed component to achieve wave dissipation, anti-scouring and ecological functions is as follows:

[0063] The above three double-connected components are hung on the hook of the crane. With the help of the positioning system, the hook is moved to the designated position around the wind turbine foundation, and the double-connected components on the hook are released. Four layers are thrown in layer by layer. The four layers are tightly filled to form cross-connections and cross-rolling of the double-connected components, which significantly improves the stability of the overall structure; they are coupled with each other to form multi-angular and hollow accumulations, which constitute resistance and energy dissipation units for incoming waves and currents, play a role in reducing flow velocity and scouring, and integrate wave breaking, anti-scouring and ecological functions.

[0064] After the double-joined components in the above embodiment of the present invention are thrown around the marine engineering foundation, multiple double-joined components are coupled to each other to form a pile with multiple edges and holes, which constitutes a resistance unit for the incoming wave current, plays a role in reducing the flow rate and reducing the scouring ability, and because multiple double-body components are crossed and coupled with each other, they are not easily moved by the wave current, and aquatic organisms can live in the hollow interior and between the blocks. The above embodiment of the present invention provides an effective protection device for local anti-scouring protection of marine engineering foundations such as pile piers, groins, and seawalls, and an ideal place for aquatic organisms to live, with the advantages of convenient construction and low cost.

[0065] The above describes the specific embodiments of the present invention.
