Problems solved by technology

[0003] The existing fan foundation is driven into the seabed through the suction barrel, and the seawater in the suction barrel is evacuated through a vacuum device to form a vacuum environment, so that the suction barrel is adsorbed on the seabed. However, due to the irregular seabed, the vacuum The area is irregular, which easily leads to unbalanced force and reduces the stability of the structure

Abstract

The invention relates to the technical field of electricity generation devices, in particular to an offshore wind turbine foundation comprising grouting assemblies, suction force barrels and a guide pipe frame arranged on the suction force barrels. Each grouting assembly comprises a grouting pipe, a flow distributor and multiple flow distribution pipes which are sequentially connected. Each suction force barrel is provided with a suction force cavity. An opening is formed in the lower end of each suction force cavity. A water drainage opening is formed in the upper end of each suction force cavity. The outlet ends of the flow distribution pipes are arranged on the upper portions of the suction force cavities and are used for conducting grouting towards in the inner portions of the suctionforce cavities. The invention further provides a grouting construction method of the offshore wind turbine foundation, dependence of the wind turbine foundation installation on engineering geology isreduced, the construction effect and the economical performance are improved, the force bearing mode of the suction force barrels is changed, seawater in the suction force barrels is discharged, the effect of sealing the suction force cavities is achieved, a stable force bearing structure is formed below the wind turbine foundation, and stability of the foundation is improved.

Description

technical field [0001] The invention relates to the technical field of power generation equipment, in particular to an offshore fan foundation and a grouting construction method thereof. Background technique [0002] In the prior art, in order to set up wind power generation equipment at sea, the fan foundation is usually installed on the seabed. On the one hand, it needs to bear the wave load, water flow load and impact force it receives, and on the other hand, it needs to bear the self-weight and impact of the wind turbine. The loads imposed by the wind, therefore, the stability of the wind turbine foundation setup is of great significance. [0003] The existing fan foundation is driven into the seabed through the suction barrel, and the seawater in the suction barrel is evacuated through a vacuum device to form a vacuum environment, so that the suction barrel is adsorbed on the seabed. However, due to the irregular seabed, the vacuum The area is irregular, which easily l...
