Description

Suction type jacket foundation structure applied to wind measuring tower of offshore wind farm Technical Field The application relates to the field of wind towers of offshore wind farms, in particular to a suction type jacket foundation structure applied to the wind towers of offshore wind farms. Background Offshore wind farms have been rapidly developed worldwide in recent years as an important component of renewable energy sources. In the construction of offshore wind power plants, the wind measuring tower plays a vital role, and has the main functions of collecting meteorological data such as wind speed, wind direction and the like, and providing a key basis for site selection, design and operation of the wind power plants. However, since offshore wind farms are often located in offshore remote areas, the geological conditions are complex and variable, which puts extremely high demands on the design of the anemometer tower foundation. In order to ensure the stability and safety of the anemometer tower, the related technical field is constantly exploring and optimizing basic forms. At present, the wind measuring tower foundation form commonly used in industry mainly comprises traditional structures such as a single pile foundation, a high pile cap and a four-pile jacket. These foundation forms provide support for the anemometer tower by being driven into or secured to the seabed foundation. Specifically, a single pile foundation is directly driven into the sea bottom through a large steel pipe pile, the single pile foundation is suitable for shallow water depth and hard foundations, a high pile cap is combined with a concrete cap through a plurality of steel pipe piles and is suitable for more complex geological conditions, and a four-pile jacket is formed into a frame structure through combination of a plurality of steel pipes, so that stronger bearing capacity can be provided. Although these basic forms meet the operational requirements of wind towers to some extent, they still present challenges in terms of construction difficulties, cost control, and environmental impact. The conventional foundation form described above tends to exhibit a problem of insufficient applicability in the face of soft soil foundation conditions. For example, on a soft foundation such as mucky soil or silty clay, a single pile foundation is easy to settle, the construction process of a high pile cap is complex and high in cost, and a four-pile jacket may cause excessive pressure on the foundation due to large dead weight. Therefore, how to develop a wind measuring tower foundation form which is suitable for soft soil foundations, is simple and convenient to construct and is environment-friendly becomes a technical problem to be solved currently.

The application provides a suction type jacket foundation structure applied to a wind measuring tower of a marine wind power plant, which adopts the following technical scheme: A suction type jacket foundation structure applied to a wind measuring tower of a marine wind power plant comprises a jacket main body, a plurality of suction barrels and a pumping device communicated with the interiors of the suction barrels, wherein the suction barrels are arranged at the bottom of the jacket main body and are downward in opening, and when the jacket main body is sunk and installed, the pumping device is used for pumping water in the suction barrels so as to form a negative pressure effect. Through adopting above-mentioned technical scheme, this suction formula jacket foundation structure can effectively be applicable to the construction demand of offshore wind farm anemometer tower. Through set up a plurality of openings suction barrels down in jacket main part bottom to utilize pumping device to extract the water in the suction barrel and form the negative pressure effect, realized that the jacket basis is quick, stable the settlement in soft soil foundation, showing the construction degree of difficulty and cost that has reduced. The design does not need to carry out large-scale excavation and backfilling operation, reduces the influence on the marine ecological environment, and has good environmental protection performance. And the introduction of the negative pressure effect enhances the binding force between the suction barrel and the foundation, improves the bearing capacity of the foundation and the stability of the whole structure, and ensures the safe operation of the anemometer tower under extreme weather conditions. Preferably, the jacket main body comprises a plurality of main pipes and supporting pipes connected between the main pipes, the lower ends of the main pipes are expanded to the outer side of the jacket main body, and the suction barrels ar
