Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ocean engineering, in particular, to a double-connection component integrating wave dissipation, scour prevention and ecology and application thereof. BACKGROUND

[0002] Through domestic and foreign literature retrieval, there are many structure types for wave dissipation, such as the X-shaped artificial armor wave dissipation block disclosed in Chinese Patent Application No. 201911192777.1, the triple-type wave dissipation block disclosed in Chinese Patent Application No. 200810153738.6, and the traditional wave dissipation plate, twisted block and twisted king block, etc., but these structure forms do not have ecological function.

[0003] There are also many scour protection measures, such as artificial water grass mat, floating curtain siltation promoting plate, scour prevention mat, riprap, geotechnical plant mat, tetrahedron, hexahedron, etc., as well as integrated technologies of these measures, such as the semi-submersible layered scour prevention and siltation promotion device disclosed in Chinese Patent Application No. 202010770368.1, which is a layered integration of artificial water grass, floating curtain siltation promoting plate and other scour prevention measures, but these measures have weak wave dissipation function and often lack ecological function, and the stability on the seabed needs to be strengthened.

[0004] Therefore, it is of great significance to develop a man-made structure integrating ecology, wave dissipation and scour protection functions.

[0005] Through retrieval, it is found that the Chinese Utility Model Patent with the authorization announcement No. CN211898178U discloses a concave hexagonal prism armor block and armor structure, which comprises a hexagonal prism block, the opposite sides of the hexagonal prism block are inwardly recessed, the top surface of the hexagonal prism block is provided with a wave dissipation hole passing through the bottom surface, the front side of the hexagonal prism block is provided with a hole passing through the rear side, the hole is in communication with the wave dissipation hole, when a plurality of hexagonal prism blocks are installed on the dam armor, the recessed surfaces and the top and bottom surfaces of adjacent hexagonal prism blocks are arranged closely, so that the adjacent hexagonal prism blocks have a pressing force and form an armor structure, the wave dissipation hole and the hole provided on the hexagonal prism block not only can reduce the wave action force, but also can provide a habitat for fish due to the low flow rate in the body and between adjacent bodies. Although this technology realizes the ecological, wave dissipation and scour protection functions, it is difficult to construct and cannot be directly thrown. Otherwise, the gaps between these blocks are too large and too many, and the mutual overlapping part is less, which not only reduces the scour prevention effect, but also causes poor stability of the blocks.

[0036] Referring to Figure 1 As shown in the figure, the double body component integrating wave dissipation, scour prevention and ecology provided by an embodiment of the present application comprises a hollow pentahedron 1, a solid hexahedron 2, a hanging ring 4 and a flexible connecting piece 3, wherein: the hollow pentahedron 1 is a triangular prism, a cylindrical cavity is arranged in the interior of the hollow pentahedron 1 along the height direction of the triangular prism, the cylindrical cavity is located at the center position of the hollow pentahedron 1, the cylindrical cavity is a non-through cavity, the distance from the top and bottom of the hollow pentahedron 1 to the end of the cylindrical cavity is equal, and holes 5 are respectively arranged between the top of the triangular prism and the top end of the cylindrical cavity, between the bottom of the triangular prism and the bottom end of the cylindrical cavity and between the three side faces of the triangular prism and the cylindrical cavity; the hanging ring 4 is arranged at the top of the hollow pentahedron 1; the solid hexahedron 2 comprises an upper part and a lower part, the upper part is a prism surrounded by multiple equilateral triangles, the upper part is symmetrical to the lower part and the sizes of the two parts are the same; one end of the flexible connecting piece 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.

[0037] In the embodiment of the present application, the hollow pentahedron 1 can reduce the specific gravity of the block and increase the sedimentation resistance, so that the free sinking speed is small when throwing and filling; after touching the bottom, different directions of multiple fluid streams collide with each other, the energy consumption is increased, the attack power and flow rate of the incoming flow are reduced, and the habitat of underwater organisms is formed; the specific gravity of the solid hexahedron 2 is high, the free sinking speed is fast, and the solid hexahedron 2 of the double body component is ensured to touch the bottom earlier than the hollow pentahedron 1, the hollow pentahedron 1 reaches the seabed surface later, and the hollow pentahedron 1 lands on the downstream of the solid hexahedron 2 due to the pushing of the wave flow during the falling process of the hollow pentahedron 1, that is, the solid hexahedron 2 is located upstream of the hollow pentahedron 1, the solid hexahedron 2 and the hollow pentahedron 1 are staggered and laid on the solid hexahedron 2 and the hollow pentahedron 1 in the lower layer when throwing and filling in the upper layer, and the solid hexahedron 2 is mostly pressed in the lower layer, while the hollow pentahedron 1 in the upper layer is pulled by the solid hexahedron 2 below to prevent the wave flow from washing away. This staggered and interrelated structure can automatically realize the stable structure of mutual staggered layers, and the double body component formed by other shapes is not easy to form the stable structure.

[0038] In the embodiment of the present application, through the mutual cooperation between the hollow pentahedron 1, the solid hexahedron 2 and other structures, multiple double body components are coupled with each other, cross-rolled and formed into a multi-angled and multi-holed accumulation body, and gaps are formed between the accumulation bodies, the accumulation body constitutes a resistance and energy dissipation unit for the incoming wave, which can effectively eliminate most of the energy of the external wave flow, significantly reduce the incoming wave flow rate and reduce the wave climbing height and overtopping amount.

[0039] The embodiment of the present application forms a multi-angled and multi-holed accumulation body through multiple double-connection components, significantly improves the overall structural stability, and enhances the anti-tilting and anti-sliding stability against wave flow; moreover, the accumulation body can significantly reduce the internal flow rate, weaken the wave flow scouring capacity, effectively promote the sediment deposition, and play a protective role in promoting deposition and preventing scouring for the marine engineering foundation.

[0040] The embodiment of the present application can significantly reduce the wave intensity inside and around the block, and the double-connection components are crossed and coupled with each other, and are not easy to be moved by wave flow, so that aquatic organisms can inhabit in the inside of the hollow pentahedron 1 and around the double-connection component block, thereby playing a role of fish reef.

[0041] In some embodiments, the bottom surface and the top surface of the hollow pentahedron 1 are parallel, the bottom surface and the top surface are of 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 0.4 m, 0.9 m and 1.8 m, respectively; the height of the three-prism block is 1.2 m.

[0042] In some embodiments, the axis of the cylindrical cavity is perpendicular to the two parallel surfaces of the hollow pentahedron 1, and preferably, the diameter of the cylindrical cavity is 0.2 m and the height is 1.4 m, thereby playing a role of energy dissipation, flow slowing, providing habitat for aquatic organisms, etc. Holes are respectively opened from the two end surfaces of the cylindrical cavity to the two parallel surfaces of the three-prism block, and holes are respectively opened from the three side surfaces of the three-prism block to the cylindrical cavity, thereby forming a five-hole structure connected inside and outside, and preferably, the hole diameter of the hole 5 is 0.2 m, thereby achieving the effects of energy dissipation, flow slowing, providing habitat for aquatic organisms, etc. through the hole 5.

[0043] In some embodiments, the solid hexahedron 2 is a solid body made of concrete or reinforced concrete, the upper and lower bottom surfaces of the solid hexahedron 2 are prisms or streamline ellipsoids surrounded by three equilateral triangles, and preferably, the height of the upper and lower parts of the solid hexahedron is 0.3 m, and the top angle of the solid hexahedron 2 is equal to 60°, which is arranged to ensure the stability under the action of wave flow during storm surge.

[0044] In some embodiments, the flexible connecting piece 3 is made of an ultrahigh molecular organic material that is resistant to corrosion, ultraviolet rays and salt, and exemplarily, the flexible connecting piece 3 adopts a cable; the diameter of the flexible connecting piece 3 is 0.01-0.03 m, and the length is 1 m-5 m, thereby realizing the connection of the hollow pentahedron 1 and the solid hexahedron 2.

[0045] In some embodiments, the hanging ring 4 is made of an ultrahigh molecular organic nylon material that is resistant to corrosion, ultraviolet rays and salt, the diameter of the hanging ring 4 is 0.03-0.06 m, and the length is 0.1 m-0.3 m, thereby hanging the double-connection component to the hook of the crane to realize the launching of the double-connection component.

[0046] Based on the same inventive concept, another embodiment of the present application provides an application of the aforementioned double-connection component integrating wave dissipation, impact prevention and ecology, which comprises: throwing a plurality of the aforementioned double-connection components around the marine engineering foundation, and coupling them to form a multi-angled and hole-accumulated body.

[0047] In some embodiments, the minimum weight of the anti-sliding and anti-tilting of the hollow pentahedron 1 of the double-connection component is determined according to the maximum wave force and moment, and the weight of the hollow pentahedron 1 is greater than the minimum weight, such as the weight of the hollow pentahedron block corresponding to the design safety factor 1.5, which is used as the wave dissipation main component, i.e. the weight of the hollow pentahedron is 1.5 times the minimum weight. Specifically, the critical wave flow under the action of the grain starting shear stress τ 0m and the specific gravity γ of the hollow pentahedron 1 s The corresponding starting condition is: The particle size d is obtained Therefore, the equivalent particle size of the hollow pentahedron 1 is Thus, the minimum weight of the anti-sliding and anti-tilting of the hollow pentahedron 1 is obtained.

[0048] On the water-facing surface of the seawall, the solid hexahedron 2 is laid on the lower layer (the gap between the hollow pentahedrons 1), and the flexible connecting piece is stretched to tightly and staggeredly lay the hollow pentahedron 1 on the upper layer (on the surface of the solid hexahedron 2), and a plurality of hollow pentahedrons 1 are coupled to form a multi-angled and hole-accumulated body, which constitutes a resistance and energy dissipation unit to the incoming wave flow, and plays a role in reducing the flow velocity, reducing the wave height and overtopping amount.

[0049] In the above embodiment, for the upper layer block, in addition to the wave flow force, the drag force of the flexible connecting piece pressed on the lower layer solid hexahedron 2 is increased, so that the upper layer block is difficult to start. The solid hexahedron 2 is pressed on the lower layer by the upper layer hollow pentahedron 1, so that there is generally no starting problem after construction is completed.

[0050] In some embodiments, the minimum starting weight of the hollow pentahedron 1 is determined according to the maximum bed shear stress under the action of the wave flow (minimum starting weight = maximum bed shear stress × bottom area of hollow pentahedron / friction coefficient of local 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 1.3;

[0051] Hang the hanging ring 4 of the double-connection component on the hook of the crane, move the hook to the designated position around the foundation of the offshore engineering building such as the pile, the riser, the wind power foundation and the like by means of the positioning system, release the double-connection component on the hook, and form the mutually coupled accumulation body by adopting the throwing filling 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 sea is greater than that of the hollow pentahedron 1, and the falling speeds of the two are equal only when the cable is tight. Therefore, the solid hexahedron 2 will first reach the seabed surface, and the hollow pentahedron 1 will reach the seabed surface later, but the hollow pentahedron 1 lands downstream of the solid hexahedron 2 during the falling process due to the pushing of the wave flow, so as to press the cable and the solid hexahedron 2 of the first throwing layer, and the multi-layer close throwing filling will form the cross hook connection and cross rolling of the lower double-connection component, and significantly improve the overall structural stability; the mutually coupled accumulation body with multiple edges and cavities forms the resistance and energy dissipation unit to the incoming wave flow, and plays the role of reducing the flow velocity and reducing the scour.

[0052] In some embodiments, the minimum weight of the double-connection component against sliding and tilting is determined according to the maximum wave force and moment, and the calculation method is similar to that of determining the minimum weight of the hollow pentahedron 1 of the double-connection component against sliding and tilting, and the weight of the double-connection component is greater than the minimum weight of the double-connection component against sliding and tilting, such as the weight of the double-connection component block corresponding to the design safety factor 1.3;

[0053] Hang the hanging ring 4 of the double-connection component on the hook of the crane, move the hook to the designated position around the foundation of the offshore engineering building such as the pile, the riser, the wind power foundation and the like by means of the positioning system, release the double-connection component on the hook, and form the mutually coupled accumulation body by adopting the throwing filling 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 sea is greater than that of the hollow pentahedron 1, and the falling speeds of the two are equal only when the cable is tight. Therefore, the solid hexahedron 2 will first reach the seabed surface, and the hollow pentahedron 1 will reach the seabed surface later, but the hollow pentahedron 1 lands downstream of the solid hexahedron 2 during the falling process due to the pushing of the wave flow, so as to press the cable and the solid hexahedron 2 of the first throwing layer, and the multi-layer close throwing filling will form the cross hook connection and cross rolling of the lower double-connection component, and significantly improve the overall structural stability; the mutually coupled accumulation body with multiple edges and cavities forms the resistance and energy dissipation unit to the incoming wave flow, and plays the role of reducing the flow velocity and reducing the scour.

[0054] The above embodiments of the present application can simultaneously realize the functions of wave dissipation, scour protection and fish reef construction, and can significantly improve the stability of the block.

[0055] In a specific embodiment, a double conjoined member for siltation and scour prevention around a wind power foundation with a pile diameter of 8m is provided, mainly comprising a hollow pentahedron 1, a flexible connecting piece 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 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 that is connected internally and externally. The upper part of the solid hexahedron 2 is a prism surrounded by multiple isosceles triangles, and the top angle is equal to 45°. The upper part is symmetrical to the lower part. The hollow pentahedron 1 and the solid hexahedron 2 are connected by the flexible connecting piece 3, and the hanging ring 4 is arranged at the top of the hollow pentahedron 1.

[0056] The hollow pentahedron 1 is made of concrete, and the bottom and top surfaces have a side length of 0.5m and an included angle of 45°. The length of the prism is 1.2m.

[0057] The solid hexahedron 2 is a solid body made of concrete. The upper part is a prism surrounded by three isosceles triangles, and the top angle is equal to 60°. The upper part is symmetrical to the lower part, and the height is 0.3m.

[0058] The flexible connecting piece 3 is a cable made of HDPE material, with a diameter of 0.02m and a length of 3m.

[0060] The hole 5 is arranged in the hollow pentahedron 1, with a hole diameter of 0.35m and an internal hollow cylindrical cavity diameter of 0.35m and a length of 0.9m.

[0061] The implementation process of the double conjoined member to realize wave dissipation, scour prevention and ecological function is as follows:

[0062] The above three double conjoined members are hung on the hooks of the crane, and the hooks are moved to the designated position around the wind power foundation by means of the positioning system. The double conjoined members on the hooks are released, and four layers are thrown and filled in this way. The close throwing and filling of the four layers will form the cross hooking of the double conjoined members, cross rolling, and significantly improve the overall structural stability. The mutual coupling forms a multi-angled and hollow accumulation body, which constitutes a resistance and energy dissipation unit for the incoming wave flow, plays a role in reducing flow velocity and reducing scour, and integrates wave dissipation, scour prevention and ecological function.

[0063] The double-connection components in the above-mentioned embodiments of the present application are thrown into the sea around the marine engineering foundation, and are coupled with each other to form a pile of multi-angled and multi-holed bodies, which constitute a resistance unit for the incoming wave flow, and play a role in reducing the flow speed and the scouring capacity. Since the double-connection components are crossed and coupled with each other, they are not easily moved by the wave flow, and aquatic organisms can inhabit in the hollow interiors and between the bodies. The above-mentioned embodiments of the present application provide an effective protection device for the local scouring protection of the marine engineering foundation such as the pile, the spur dike, the seawall, and an ideal habitat for aquatic organisms, and have the advantages of convenient construction and low cost.
