[0002] Offshore wind power has the characteristics of abundant resources, high power generation utilization hours, no land occupation and suitability for large-scale development. It is the latest frontier of global wind power development.

[0003] In the prior art, after the piles of high-pile docks are sunk in water, the piles must be clamped as soon as possible to prevent the single foundation pile from being excessively displaced or even unstable due to factors such as waves and deadweight. Pile clamping is a temporary measure before the enclosure process. Generally, several foundation piles are connected into a whole by welding channel steel. However, under severe sea conditions, the quality of on-site welding is difficult to guarantee. The horizontal wave force causes the foundation piles to be displaced significantly. The rigidity of the connection is limited only by channel steel, and the welding phenomenon often occurs, which affects the safety of the foundation pile structure during the construction period.

[0028] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0029] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0030] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0031] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0032] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0033] The utility model provides an above-water pile clamping device, referring to Figure 1 and Figure 2 As shown, the embodiment of the utility model provides an above-water pile clamping device, comprising: a working platform 10, a fixing structure 20 and a limiting structure 30;

[0034] The working platform 10 includes a main beam and a supporting beam, a plurality of main beams are connected along the edge of the working platform, and the supporting beams are connected inside the plurality of main beams;

[0035] The working platform 10 includes a plurality of through holes for the steel pipe piles 40 to pass through;

[0036] A fixing structure 20 and a limiting structure 30 are arranged along a circumference of the through hole. The fixing structure 20 is fixedly connected to the steel pipe pile 40 , and the limiting structure 30 is flexibly connected to the steel pipe pile 40 .

[0037] It is understandable that the working platform 10 welded with the main beam and the supporting beam is used to provide a platform for operation. The working platform 10 adopts a steel structure, and its rigidity can resist the horizontal displacement of the foundation pile. The vertical load takes into account the construction load of the operators. The structure mainly adopts steel and mesh plates to provide a safe working platform for the subsequent enclosure process.

[0038] Furthermore, the working platform 10 is designed and constructed according to the planned number of pile clamps before the piles are sunk in the project. Generally speaking, the number of through holes in the working platform 10 is equal to the number of steel pipe piles 40. A fixing structure 20 and a limiting structure 30 are provided at the through holes.

[0039] When several foundation piles at sea have been sunk, the pile clamping operation is carried out. First, the multifunctional barge carries the water pile clamping device provided by the utility model into place, and re-measures the deviation of the steel pipe pile 40. If the deviation is too large, it needs to be corrected so that the water pile clamping device can be installed smoothly. The multifunctional barge lifts the water pile clamping device. The multifunctional barge is equipped with two cables and wind ropes, which can be adjusted in a small range. The water pile clamping device and the steel pipe pile 40 are initially limited. Then, the fixed structure 20 is fixedly connected to the steel pipe pile 40, and the limiting structure 30 is flexibly connected to the steel pipe pile 40. After the connection is completed, the multifunctional barge is withdrawn from the site.

[0040] The above-water pile clamping device provided by the utility model does not require on-site welding operations, realizes modularization and prefabrication, and greatly improves on-site work efficiency. It can quickly clamp piles at sea, especially in severe sea conditions with poor wind and wave conditions, to ensure the quality of pile clamping and the safety of foundation piles.

[0041] In an optional embodiment provided by the present utility model, the limiting structure 30 includes a retractable horizontal chain 31 and a pull ring 32 connected to the end of the retractable horizontal chain 31;

[0042] The retractable horizontal chain 31 surrounds the steel pipe pile 40 , and the pull ring 32 is fixed to the working platform 10 at a position opposite to the overturning direction of the steel pipe pile 40 .

[0043] It can be understood that the limiting structure 30 is used to realize the flexible connection between the steel pipe pile 40 and the above-water pile clamping device. Specifically, the retractable horizontal chain 31 of the limiting structure 30, after the retractable horizontal chain 31 surrounds the steel pipe pile 40, fixes the pull ring 32 on the working platform 10. In addition, the fixing direction of the pull ring 32 is opposite to the overturning direction of the steel pipe pile 40.

[0044] In an optional embodiment provided by the present invention, the above-water pile clamp device is located at the top of the steel pipe pile 40, and at least above the anti-corrosion demarcation line of the foundation pile of the steel pipe pile 40. The above-water pile clamp device is fixed within 0.8m-1.5m of the top of the steel pipe pile 40, and cannot damage the anti-corrosion layer.

[0045] In another optional embodiment provided by the present invention, the working platform 10 is polygonal, and the plurality of through holes are symmetrically arranged about the geometric center of the working platform 10 .

[0046] It is understandable that the water pile clamping device is prefabricated, and its shape and number of through holes correspond to the number of steel pipe piles 40 that need to be clamped. Generally speaking, the steel pipe piles 40 are also symmetrically arranged, so the working platform 10 is a polygon, which can be a regular polygon, or can be set according to actual conditions, and the utility model does not make specific restrictions. The multiple through holes are symmetrically arranged about the geometric center of the working platform 10, which can ensure that the water pile clamping device and the steel pipe piles 40 are evenly stressed and ensure the quality of the pile clamping.

[0047] In an optional embodiment provided by the present utility model, the steel pipe piles 40 include three, which are distributed at an angle of 120° with each other;

[0048] The working platform 10 includes three through holes, and any through hole is opposite to a steel pipe pile 40;

[0049] The steel pipe pile 40 overturns in a direction close to the geometric center, and the corresponding limiting structure 30 is fixed in a direction away from the geometric center.

[0050] In this embodiment, there are three steel pipe piles 40, so the working platform 10 is a symmetrical hexagon, the through holes are evenly arranged on the horizontal platform 10, arranged at an angle of 120°, and the steel pipe piles 40 are also arranged at an angle of 120°. The steel pipe pile 40 overturns toward the geometric center, and the retractable horizontal chain 31 of the limiting structure 30 surrounds the steel pipe pile 40 and fixes the pull ring 32 in a direction away from the geometric center, exerting an opposite force on the steel pipe pile 40.

[0051] In another optional embodiment provided by the present invention, the retractable horizontal chain 31 includes multiple pull rings 32 that are evenly spaced and arranged on the same straight line, and the straight line where the pull rings 32 are located is perpendicular to the line connecting the steel pipe pile 40 and the geometric center.

[0052] It is understandable that the retractable horizontal chain 31 includes a plurality of chains, and any retractable horizontal chain is wound around the steel pipe pile 40 for several turns. Due to the retractable performance, the pull ring 32 at the end of the retractable horizontal chain 31 can be fixed at any position and keep the chain relatively straight.

[0053] Furthermore, multiple pull rings 32 can be arranged on the same straight line, which is perpendicular to the line connecting the steel pipe pile 40 and the geometric center, to ensure that the steel pipe pile 40 receives the balanced pulling force of multiple retractable horizontal chains 31. The fixing direction of multiple pull rings 32 on the working platform 10 is the same as the extending direction of the ends of the retractable horizontal chains 31 connected thereto, which also ensures balanced force.

[0054] In another optional embodiment provided by the present invention, the thickness of the fixed structure 20 along the horizontal direction is not less than 35 cm, so as to ensure the clamping quality of the fixed structure 20 on the steel pipe pile 40 .

[0055] In summary, the above-water pile clamping device provided by the utility model achieves at least the following beneficial effects:

[0056] The above-water pile clamping device provided by the utility model does not require on-site welding operations, realizes modularization and prefabrication, and greatly improves on-site work efficiency. It can quickly clamp piles at sea, especially in severe sea conditions with poor wind and wave conditions, to ensure the quality of pile clamping and the safety of foundation piles.

It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention.
