Description

Technical Field

[0001] This utility model relates to the field of marine engineering foundation construction, specifically to narrow-wing pile anchors. Background Technology

[0002] In marine engineering, pile-anchor structures, as common foundation components, play a crucial role in fixing and supporting the superstructure. Currently, pile-anchors are widely used in marine engineering due to their advantages, including strong adaptability to deep-water environments, high load-bearing capacity, minimal environmental impact, and low maintenance requirements. With the application of large-scale floating wind turbine foundations, mooring forces are increasing. Traditional offshore anchor piles, mostly using a columnar design, are typically used for single mooring systems, resulting in high costs. This is particularly problematic in deep-water or complex seabed environments, where there are numerous anchor points and significant construction difficulties at sea. Traditional pile-anchor structures also have some shortcomings. For example, the anchoring force of the pile in the soil is insufficient to meet the engineering requirements under complex geological conditions. Specialized positioning and stabilization equipment is required during the lifting and installation of the pile, and the structural strength and stability of the lifting components are relatively poor, making them prone to damage or pile / anchor falling, thus affecting construction progress and safety. Therefore, the overall structural strength of existing pile-anchor structures needs improvement, as they cannot withstand large tensile and compressive forces, limiting their application in some large-scale engineering projects.

[0003] Based on this, we propose a narrow-wing pile anchor. Utility Model Content

[0004] In order to solve the technical problems existing in the prior art, the present invention provides a narrow-wing pile anchor.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a narrow-wing pile anchor, comprising a pile body, wherein wing plates are evenly distributed and welded to the outside of the pile body, and an ear plate is provided at the lower middle position of the wing plate to facilitate lifting and installation of the pile anchor, and a reinforcing steel plate is welded to the ear plate, the reinforcing steel plate being disposed on both sides of the wing plate.

[0006] Preferably, the pile body is a cylinder made of high-strength steel, which gives it good compressive, tensile and shear resistance.

[0007] Preferably, the wing plate is made of high-strength steel plate and has a narrow strip structure. The wing plate can increase the contact area between the pile anchor and the soil, thereby improving the anchoring force of the pile anchor in the soil and enabling it to better withstand tensile and compressive forces.

[0008] Preferably, the reinforcing steel plate is a circular or rectangular steel plate made of high-strength steel, used to enhance the structural strength of the ear plate. The reinforcing steel plate effectively improves the load-bearing capacity at the ear plate, preventing deformation or breakage of the ear plate during lifting.

[0009] Compared with the prior art, the present invention provides a water swirl core tube, which has the following beneficial effects: (1) Introducing the concept of shared anchor, the anchor chain is suspended in multiple directions, and the tension of the anchor chain is evenly distributed in multiple directions, which effectively solves the problem of uneven force caused by the single ear plate of traditional pile anchor.

[0010] (2) Diverse structural forms: Narrow wing pile anchors include pile body and wing plates. The number of wing plates can be assembled according to the actual geological conditions, such as three wings, four wings, six wings, eight wings, nine wings, etc.

[0011] (3) Increase anchoring force: By setting narrow strip wing plates, the contact area between the pile anchor and the soil is increased, which effectively provides the ability to resist pull-out and horizontal movement, and improves the anchoring force of the pile anchor in the soil.

[0012] (4) Strong erosion resistance: Narrow-wing pile anchors can penetrate deep into the mud layer and form a tight bond with the surrounding soil, increasing the friction and interlocking force between the anchor and the soil. Even under long-term water erosion, they can still maintain a stable anchoring state. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0016] The narrow-wing pile anchor proposed in this embodiment, such as Figures 1 to 3 As shown, the narrow-wing pile anchor includes a pile body 1, wing plates 2, ear plates 3, and reinforcing steel plates 4. The pile body 1 is a cylindrical shape made of high-strength steel, such as Q345D alloy steel, with a diameter of 500mm and a length of 10000mm, possessing good compressive, tensile, and shear resistance. The surface of the pile body 1 can be provided with anti-slip textures, distributed in a spiral pattern, which increases the friction between the pile body 1 and the soil, improving the stability of the pile anchor. The wing plates 2 are located on the outer side of the pile body, in the form of narrow strips, evenly distributed along the circumference of the pile body 1. The wing plates 2 are made of high-strength steel plates and are firmly connected to the pile body 1 by welding. During the welding process, a double-sided welding process is used to ensure welding quality. The design of the wing plates 2 increases the contact area between the pile anchor and the soil, thereby improving the anchoring force of the pile anchor in the soil, enabling the pile anchor to better withstand tensile and compressive forces. Ear plates 3 are located in the lower middle part of the flange 2, approximately two-thirds of the flange 2's height. The ear plates have a circular hole cut out as required by the design and are used for lifting and installing pile anchors. Reinforcing steel plates 4 are placed around the ear plates 3 on the flange 2 to enhance the structural strength at the ear plates 3. The reinforcing steel plates 4 are made of high-strength steel. The shape of the reinforcing steel plates 4 is circular or rectangular, and their dimensions are designed according to the size of the ear plates 3 and the flange 2. The reinforcing steel plates 4 are connected to the flange 2 by welding, effectively improving the load-bearing capacity at the ear plates 3 and preventing deformation or breakage during lifting.

[0017] The installation steps for narrow-wing pile anchors are as follows: (1) The pile body 1, wing plate 2, ear plate 3 and reinforcing steel plate 4 are fabricated according to the engineering design requirements and then welded into the designed narrow wing pile anchor integral structure.

[0018] (2) After arriving at the construction site, connect the mooring anchor cable to the 6 ear plates 3 on the narrow wing pile anchor to complete the equipment installation.

[0019] (3) The finished pile anchor is hoisted and launched into the water. The pile anchor is lifted by the hoisting equipment through the ear plate 3 and slowly lowered into the water to ensure that the pile anchor is perpendicular to the seabed and enters the mud.

[0020] (4) Use the hammer required by the design to carry out the narrow-wing pile anchor penetration construction. During the penetration process, ensure the verticality of the pile anchor until the design depth is reached and then stop. The installation is then complete.
