[0002] New energy power generation methods mainly include solar power generation and wind power generation. Among them, wind turbine generator sets have gradually reached new heights with the continuous development of technology. Nowadays, direct-drive wind turbine generator sets adopt a horizontal axis, three blades, upwind direction, variable pitch adjustment, direct drive, and grid connection of permanent magnet synchronous generator, which is superior to traditional asynchronous generators. After constructing the beam-plate structure wind turbine foundation, it is necessary to pour concrete to form a complete wind turbine foundation.

[0003] The existing concrete pouring method for beam-slab structure wind turbine foundations has the following technical defects: The traditional concrete pouring method for wind turbine foundations mainly achieves the pouring of various parts of the wind turbine foundation by manually controlling the concrete discharge pipes. This pouring method results in uneven distribution of concrete during pouring, which leads to the need to clean up the poured concrete by means of vibration and other methods, thus increasing the pouring time of the wind turbine foundation. Moreover, the dismantling method is relatively complicated and cannot be dismantled quickly. Utility Model Content

[0004] This utility model proposes an integrated prefabricated cast-in-place beam-slab type wind turbine foundation structure, which solves the problems in related technologies where uneven concrete distribution during pouring leads to the need for post-pouring concrete compaction, resulting in increased wind turbine foundation pouring time and complex disassembly methods that cannot be quickly disassembled.
