Description

Technical Field

[0001] This utility model relates to the field of coastal protection engineering technology, and in particular to a novel claw-shaped ecological protection structure. Background Technology

[0002] Coastal protection engineering targets the deep-water areas beneath the coastline. Its main purpose is to limit seabed erosion and downcutting, prevent the development of narrow and deep coastlines, and mitigate the adverse effects of declining water levels on navigation. These areas are characterized by significant depth, rapid currents, and complex three-dimensional flow structures, making them susceptible to strong scouring. Coastal protection engineering primarily employs backfill materials to suppress seabed erosion, increase water flow resistance, control water level drops, and ultimately raise water levels. Traditional coastal protection structures are often solid blocks, relying heavily on concrete or metal supports, making it difficult to balance permeability and stability. They also isolate aquatic life from the land, negatively impacting the marine ecosystem. Therefore, traditional coastal protection structures have limitations in terms of ecological protection.

[0003] To address these issues, we designed a novel claw-shaped ecological bottom protection structure. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a novel claw-shaped ecological bottom protection structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel claw-shaped ecological bottom protection structure includes longitudinal beams, claw hooks, support columns, and crossbeams. Two longitudinal beams are arranged side by side in parallel. The middle of the two longitudinal beams is fixedly connected to both ends of the crossbeam. The upper end of the middle part of the crossbeam is fixedly connected to the lower end of the support column. The upper end of the support column is fixedly connected to one end of the claw hook. The other end of the claw hook is fixedly connected to one side of the upper end of the longitudinal beam. Four claw hooks are provided. The two ends of the longitudinal beam are respectively fixedly connected to the end of each claw hook.

[0007] In a further preferred embodiment of this scheme, both the longitudinal beam and the transverse beam are plate-like structures, with the same width and thickness, and the width of the longitudinal beam is equal to half the length of the transverse beam.

[0008] In a further preferred embodiment of this scheme, the outer periphery of the claw hook has a tetrahedral structure, and the claw hook structure path is a quarter-circle arc.

[0009] In a further preferred embodiment of this scheme, the planes containing the axes of any two adjacent claw hooks are perpendicular to each other.

[0010] In a further preferred embodiment of this scheme, the support column is a cylindrical structure with a diameter not greater than the width of the crossbeam.

[0011] In a further preferred embodiment of this scheme, the longitudinal beam, claw hook, support column, and crossbeam are integrally formed using a concrete casting method with molds, and reinforcing bars are provided inside the longitudinal beam, claw hook, support column, and crossbeam.

[0012] In a further preferred embodiment of this scheme, the junction between the end of the claw hook and the top of the support column is an arc-shaped surface.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model utilizes the interlacing of longitudinal beams and transverse beams to form a mutually constrained overall structure for the revetment, which greatly improves the stability of the coastal revetment structure and can effectively resist water flow impact and wave erosion. At the same time, the revetment structure can also be permeable, without hindering the contact between aquatic organisms and the land area, and does not have a negative impact on the marine ecosystem. As an artificial reef, it provides a good spawning site and a safe habitat for aquatic organisms, which helps to protect and increase the number and variety of aquatic organisms.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Coastal revetment structures are mainly classified into three categories: riprap revetment, flexible ballast concrete block revetment, and other revetment methods. Riprap revetment has been used extensively and for a long time in coastal engineering, offering advantages such as readily available materials, simple and flexible construction, and the ability to be implemented in phases. Riprap revetment is adaptable to complex conditions such as water depth, bank slope, and current velocity, and can resist damage caused by ship punting and anchoring. It has mature construction experience and significant scour protection, but its overall integrity and flexibility are relatively poor. Flexible ballast concrete block revetment has good integrity and inherent strength, and can automatically adjust its strain capacity, especially when subjected to scouring, it can quickly compensate and adjust to prevent further damage. However, flexible ballast concrete block revetment cannot withstand direct scouring for extended periods and requires protective ballast to dissipate energy and stabilize the ballast. Therefore, it is necessary to develop revetment structures with multiple functions, including scour resistance, wave protection, and environmental friendliness.

[0019] This embodiment introduces a novel claw-shaped ecological bottom protection structure, which combines multiple functional advantages such as erosion resistance, wave protection, and environmental protection. Figure 1 As shown, the structure includes a longitudinal beam 1, a claw hook 2, a support column 3, and a crossbeam 4.

[0020] Two longitudinal beams 1 are arranged side by side in parallel. The middle of the two longitudinal beams 1 is fixedly connected to both ends of the crossbeam 4, forming an "H"-shaped combination structure. The upper end of the middle part of the crossbeam 4 is fixedly connected to the lower end of the support column 3. The upper end of the support column 3 is fixedly connected to one end of the claw hook 2, and the other end of the claw hook 2 is fixedly connected to one side of the upper end of the longitudinal beam 1.

[0021] The longitudinal beam 1, claw hook 2, support column 3 and cross beam 4 are integrally formed by concrete casting using a mold, and steel bars are provided inside the longitudinal beam 1, claw hook 2, support column 3 and cross beam 4.

[0022] It should be further explained that in this embodiment, four claw hooks 2 are provided. The two ends of each longitudinal beam 1 are fixedly connected to the ends of each claw hook 2, and the four ends of the two longitudinal beams 1 are fixed to the ends of the four claw hooks 2.

[0023] It is particularly important to note that both the longitudinal beam 1 and the transverse beam 4 are plate-like structures, with the same width and thickness. However, the width of the longitudinal beam 1 is equal to half the length of the transverse beam 4. This allows two longitudinal beams 1 to be inserted side by side, with the ends of the two longitudinal beams 1 abutting against the sides of the transverse beam 4.

[0024] It is worth mentioning that the outer contour of the claw hook 2 is a tetrahedral structure, and the structural path of the claw hook 2 is a quarter-circle arc. Among the four claw hooks 2, the plane containing the axes of any two adjacent claw hooks 2 is perpendicular. The support column 3 is a cylindrical structure, and its diameter is no greater than the width of the crossbeam 4. The junction between the end of the claw hook 2 and the top of the support column 3 is an arc-shaped surface.

[0025] In use, the novel claw-shaped ecological bottom protection structure proposed in this utility model involves placing multiple such structures side-by-side, with the outer surfaces of each longitudinal beam 1 abutting against each other. Another novel claw-shaped ecological bottom protection structure is then used, with the area enclosed between the crossbeam 4 and the two longitudinal beams 1 embedded at the ends of the previous set of two longitudinal beams 1. This assembly method is repeated to form a structure as shown in the image. Figure 2 The combined state shown demonstrates how the novel claw-shaped ecological seawall structure achieves a mutually constrained overall structure, greatly enhancing the overall stability of the coastal seawall while maintaining permeability. This ensures that aquatic organisms do not hinder contact with the land and does not negatively impact the marine ecosystem.

[0026] In summary, the novel claw-shaped ecological bottom protection structure proposed in this embodiment, through the integrated structure of longitudinal beam 1, claw hook 2, support column 3, and crossbeam 4, makes the entire bottom protection structure more stable and can effectively resist water flow impact and wave erosion. During high tide, it is difficult to overturn or capsize under the action of unidirectional flow, and during low tide, any blocks that have overturned or capsized under the action of water flow can return to their original positions. The design of claw hook 2 provides gaps that can serve as artificial reefs, providing a good spawning site and safe habitat for aquatic organisms, which helps to protect and increase the number and variety of aquatic organisms.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
