Description

Technical Field

[0001] This utility model relates to the field of marine engineering technology, specifically to a double-layer perforated plate guide breakwater. Background Technology

[0002] Breakwaters are crucial coastal engineering structures that protect ports, docks, coastal facilities, and coastal areas from wave erosion. Their primary function is to dissipate wave energy and reduce wave height, thereby protecting downstream infrastructure and coastal areas from wave impact and erosion. Traditional breakwater structures mainly include gravity breakwaters, sloping breakwaters, and hybrid breakwaters. However, these traditional breakwaters often have shortcomings when facing high-intensity wave impacts. For example, gravity breakwaters require large amounts of building materials, resulting in high construction costs, and are easily damaged in extreme sea conditions; while sloping breakwaters can dissipate some wave energy, their wave-dissipating effect is limited, and they occupy a large sea area.

[0003] In recent years, with the development of coastal engineering technology, some new breakwater structures have been proposed. For example, Chinese patent CN202064321U proposes a double-layer breakwater structure, which includes an outer arch breakwater and an inner arch breakwater. By staggeredly setting multiple openings, it achieves secondary wave dissipation, significantly reducing wave height behind the breakwater. Specifically, this patent uses multiple openings between the two layers of breakwater to cause waves to refract and reflect as they pass through, thus dissipating some energy. This structure improves wave dissipation to a certain extent, but some problems remain. First, its structure is complex and difficult to construct, especially requiring high precision in the setting and connection of the openings. Second, the wave dissipation effect of this patent still needs improvement when facing high-wave-height and long-period waves, especially under extreme sea conditions, where its protective capability may be insufficient.

[0004] Another related technology is Chinese patent CN113605299B, which proposes a wave-damping device for water tanks. This device further optimizes the energy dissipation effect of water flow by incorporating multiple layers of guide plates and intercepting plates. The device guides water flow through collisions and friction between different layers using the multi-layer guide plate design, thereby dissipating energy. However, this patent is mainly applied to small water bodies such as pools, and its structure and principle are not entirely applicable to breakwaters in marine environments. Furthermore, the guide plate design in this patent is relatively simple and lacks adaptability optimization for different sea conditions, resulting in limited wave-damping effectiveness in practical applications.

[0005] In summary, while existing breakwater structures improve wave dissipation and structural stability to some extent, they still suffer from problems such as structural complexity, construction difficulty, and unsatisfactory wave dissipation effects. Therefore, developing a new type of breakwater structure that is simple in structure, easy to construct, and provides good wave dissipation is of significant practical importance. Utility Model Content

[0006] To address the aforementioned problems, this invention provides a novel double-layer perforated plate breakwater structure. Through optimized design, this structure improves the breakwater's wave-dissipating effect and structural stability while reducing construction difficulty and cost. This structure is particularly suitable for ports, docks, and coastal protection in marine environments.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A double-layer perforated plate guide breakwater includes connecting piles and double-layer perforated guide plates; the connecting piles are in multiple sets, including pile caps, pile bodies and brackets; the double-layer perforated guide plates are in two sets, arranged side by side, each set including multiple perforated guide plates with multiple openings, and the connecting piles connect each set of perforated guide plates side by side into a whole.

[0009] The pile cap is installed on the top of the pile body; the brackets are one or more sets, each set of brackets is fixed on both sides of the pile body; two adjacent perforated guide plates are connected as one unit through the brackets on the pile body, and the perforated guide plates of each set are connected in sequence.

[0010] The openings are rectangular openings, and multiple openings are arranged in parallel vertically; wherein, the openings on the front opening guide plate are located at the lower part of the opening guide plate, and the openings on the rear opening guide plate are located at the upper part of the opening guide plate.

[0011] Rubber material is embedded on both sides of the inside of the cow's foot. The rubber material is wedge-shaped with a narrow top and a wide bottom, and the contact surface between the rubber material and the perforated guide plate is a curved surface with an arc.

[0012] The pile body is either hollow or solid.

[0013] The pile cap is a detachable structure.

[0014] The beneficial effects of this utility model are:

[0015] 1. By designing a double-layer perforated plate and staggering the opening positions of the front and rear guide plates, this utility model can more effectively guide water flow, increase water flow resistance, promote water flow dispersion and energy dissipation, thereby significantly improving the wave-dissipating performance of the breakwater.

[0016] 2. The rubber material embedded on both sides of the inner side of the connecting pile structure can effectively absorb and buffer the swaying caused by water flow vibration, thus enhancing the stability and durability of the entire breakwater structure.

[0017] 3. The perforation design on the surface of the perforated guide plate is based on the principle of fluid dynamics, which can achieve optimal water flow guidance and energy dissipation, and reduce the impact of waves on the breakwater.

[0018] 4. The structural design of this utility model takes into account the convenience of construction. Through modular design and the use of prefabricated components, the difficulty and cost of on-site construction are reduced.

[0019] 5. This utility model takes into account the impact on the marine ecological environment during its design. By optimizing the structural design, it reduces the destruction of marine habitats and achieves harmonious coexistence between breakwater construction and ecological environmental protection.

[0020] 6. The pile cap of the connecting pile is designed to be detachable, which facilitates the maintenance and repair of the pile body without removing the entire connecting pile, thereby improving the maintenance efficiency of the breakwater and reducing maintenance costs.

[0026] The specific embodiments of this utility model are further described below with reference to the accompanying drawings and technical solutions.

[0027] The design of this utility model of a double-layer perforated plate guide breakwater structure includes the following aspects:

[0028] 1. Geological Environment Assessment: Before designing the breakwater structure, a detailed assessment of the geological environment of the construction site is conducted, including soil type, hydrological conditions, wave characteristics, etc., in order to determine the design parameters of the breakwater.

[0029] 2. Structural Design: Based on the geological environment assessment results, the breakwater's structural design will be carried out. The design includes the dimensions, shape, and size of the double-layer perforated guide vanes, the specifications and layout of the connecting piles, and the thickness and materials of the wave-dissipating layer. The design must consider the structure's stability, durability, and wave dissipation capabilities.

[0030] 3. Manufacturing Connecting Piles and Perforated Guide Plates: Based on the design drawings, manufacture the connecting piles and perforated guide plates. The connecting piles are made of high-strength concrete, steel pipe, or fiber-reinforced composite materials to ensure their load-bearing capacity and durability. The perforated guide plates are made of high-strength concrete or composite materials, with perforations of specific shapes and sizes designed on their surface to optimize energy dissipation during water flow.

[0031] 4. Installation of Connecting Piles and Perforated Guide Plate Structure: At the construction site, install the connecting piles and perforated guide plate structure according to the design drawings and construction plan. First, install the pile body 2 of the connecting pile, driving a certain length of one end of the connecting pile into the ground to achieve a fixing effect. Then, install the perforated guide plate on the upper half of the pile body 2. During installation, ensure the precise positioning and fixation of each component, such as the fit between the perforated guide plate and the rubber material 4 in the anchor plate 3, to ensure the stability and functionality of the entire breakwater structure. Finally, install the pile cap 1 of the connecting pile.

[0032] 5. Testing and Acceptance: After the breakwater structure is completed, a series of tests will be conducted, including structural stability tests and wave-damping effect tests, to ensure that the breakwater meets design requirements and relevant specifications. After passing the tests, the project will be accepted.

[0033] 6. Maintenance and Monitoring: Establish a maintenance and monitoring plan for the breakwater, regularly inspect its structural integrity and functional performance, and promptly carry out necessary maintenance and repairs. Monitoring includes structural displacement, settlement, cracks, etc., to ensure the long-term stability and safety of the breakwater.

[0034] like Figures 1-3As shown, this utility model discloses a double-layer perforated plate guide breakwater, comprising connecting piles and a double-layer perforated guide plate. The connecting piles are the foundation support of the breakwater, including a pile cap 1, a pile body 2, and brackets 3. The pile cap 1 is fixed to the top of the pile body 2, protecting the pile body 2 and providing a fixing constraint for the double-layer perforated guide plate. The pile body 2, as the main load-bearing part of the connecting pile structure, is designed to be hollow or solid to adapt to different construction needs and environmental conditions. The brackets 3, as the key connecting components between the connecting piles and the double-layer perforated guide plate, have rubber material 4 embedded on both sides inside, designed to fill the gap between the guide plate and the brackets 3, thereby greatly reducing the back-and-forth swaying of the plate caused by water flow oscillation and enhancing the stability of the structure. The brackets 3 are symmetrically fixed on both sides of the pile body 2, and there may be one or more sets of brackets 3. In particular, the rubber material 4 used in this utility model has unique shape design features to improve its performance and installation convenience in the double-layer perforated plate guide breakwater structure. Specifically, the rubber material 4 is designed with a wedge-shaped structure, narrower at the top and wider at the bottom. This design helps it better adapt to the bracket structure of the connecting pile during installation, thus ensuring that the rubber material 4 can be stably installed in the predetermined position. Furthermore, the contact surface between the rubber material 4 and the perforated guide plate is designed as a curved surface with a certain degree of curvature. This curved contact surface design not only facilitates the installation of the rubber material 4 and the guide plate but also ensures a tighter fit between them, thereby improving the sealing and stability of the entire structure.

[0035] The aforementioned double-layer perforated guide plate includes a front perforated guide plate 5 and a rear perforated guide plate 6, arranged in parallel and fixed by connecting piles. The surface of the guide plate is designed with a certain number of rectangular openings 7 to optimize the energy dissipation effect when water flows through. Specifically, the openings on the front and rear guide plates are staggered, with the openings 7 on the front guide plate 5 located at its lower part, and the openings 7 on the rear guide plate 6 located at its upper part. This design further optimizes the water flow path, creating a more complex flow pattern between the two guide plates, thereby improving energy dissipation efficiency. The design of the openings 7 is based on fluid dynamics principles to achieve optimal water flow guidance and energy dissipation, reducing the impact of waves on the breakwater.

[0036] Preferably, the connecting pile structure is made of high-strength, corrosion-resistant materials to ensure its stability and durability in marine environments. The specific material selection should be based on a comprehensive consideration of factors such as the design bearing capacity of the connecting pile, geological conditions, corrosion resistance, and economic feasibility. Specific materials such as Q345B grade steel, which has excellent strength and toughness, are suitable for the pile body and corbel portion of the connecting pile, especially in applications requiring the withstand of significant wave impact.

[0037] Preferably, the double-layer perforated baffle structure is made of high-strength, corrosion-resistant materials to adapt to the harsh conditions of the marine environment and improve the durability of the structure. The specific material selection should be based on a comprehensive consideration of factors such as the design load-bearing capacity of the baffle, the perforation layout, the corrosiveness of the marine environment, and economic efficiency. Specific materials such as C50 or higher grade concrete can be selected, as they possess good load-bearing capacity and durability, making them suitable for manufacturing baffles, especially in applications requiring high strength and rigidity.

[0038] Preferably, the rubber material should possess excellent elasticity, durability, and anti-aging properties to withstand the harsh conditions of the marine environment. The specific material selection should be based on a comprehensive consideration of factors such as the design load-bearing capacity, durability, elasticity requirements of the rubber components, and the corrosiveness of the marine environment. Ethylene propylene diene monomer (EPDM) rubber, known for its excellent weather resistance, ozone resistance, and heat resistance, is suitable for manufacturing rubber fillers inside connecting pile bracket structures to provide good cushioning and shock absorption performance.

[0039] Working principle as follows Figure 4 As shown, when waves crash against the breakwater, they first encounter the front guide plate. The water flows through openings of a specific shape and size designed on the front guide plate, guiding the water flow and beginning to dissipate wave energy. Subsequently, the water flows to the rear guide plate, which is arranged parallel to it. The opening position of this guide plate is offset from that of the front guide plate, further guiding the water flow and increasing its resistance, effectively dispersing and consuming wave energy. In the connecting pile structure, the rubber material embedded inside the brackets undergoes compression deformation when impacted by waves, absorbing impact energy and reducing the impact force on the guide plates. Its design, narrow at the top and wide at the bottom, and the curvature of the contact surface with the perforated guide plates provide better buffering effect and fit. In addition, the wave-dissipating layer on the seaward side of the breakwater consists of multiple layers of wave-dissipating blocks, further weakening the impact force of waves and protecting the main structure. The materials filling the flexible support structure and the fault buffer zone disperse shear stress and absorb deformation energy when geological faults shift, enhancing the stability of the entire structure. Overall, the structure, through its multi-layered flow guidance and buffer design, achieves efficient dissipation of wave energy, enhances the protective performance of the breakwater, and is suitable for the protection needs of various marine environments.
