Embodiment Construction
[0027] Such as figure 1 As shown, a reinforced concrete cap 4 is provided on the top of a plurality of pile foundations 2 to jointly form a multi-pile cap foundation for installing wind turbines in a wind farm. The bottom of the fan tower 1 is embedded in the reinforced concrete cap 4 . The connector 3 is a steel structure, and its two ends are fixedly connected with the wind tower 1 and the pile foundation 2 respectively. The connector 3 is also embedded in the reinforced concrete platform 4 . As required, the bottom of the reinforced concrete cap 4 can also be provided with a back-sealing concrete 5 .
[0028] Such as figure 2 As shown, the wind tower 1 is cylindrical, and the pile foundation 2 is distributed on the periphery of the wind tower 1 along the circumference. The top of the pile foundation 2 is provided with a pile top connection structure 31, and the cross section of the pile top connection structure 31 is cross-shaped. The top of the pile foundation 2 is pr...

The invention discloses a multi-pile bearing platform foundation based connecting structure between a fan tower drum and a pile foundation, comprising the fan tower drum, the pile foundation and a reinforced concrete bearing platform arranged at the top part of the pile foundation, wherein the bottom of the fan tower drum is embedded in the reinforced concrete bearing platform, the fan tower drumis also connected with the pile foundation through a connecting piece, and the connecting piece is in a steel structure and is provided with an I-shape cross section. In the invention, the connectingpiece is used for directly connecting the fan tower drum and the pile foundation, thereby greatly enhancing the reliability among the fan tower drum, the reinforced concrete bearing platform and the pile foundation, and the structural integrity is strengthened. The I-shape cross section connecting piece has full strength and rigidity and can entirely or partly transfer loading acting on the fan tower drum onto the pile foundation, thereby enabling loading transfer to be more direct, improving the stress condition of the reinforced concrete bearing platform and lowering the design and construction difficulties of the reinforced concrete bearing platform.
Description
technical field [0001] The invention relates to a connection structure between the wind turbine tower and the pile foundation, which is used on the multi-pile cap foundation of the fan in the wind farm. Background technique [0002] As the supporting structure of the wind farm, the wind turbine tower not only bears the self-weight of the wind turbine, but also bears the dynamic load generated during the operation of the wind turbine and the fluctuating load of the wind. The action of these loads will be transmitted to the foundation structure of the wind turbine through the wind turbine tower, so the force of the foundation structure of the wind turbine is very complicated. At present, many wind turbine foundations in existing wind farms use multi-pile cap foundations, that is, reinforced concrete caps are poured on the top of the pile foundations, and the bottom of the wind turbine tower is embedded in the reinforced concrete caps. The load on the barrel is transferred to ...
