The method for manufacturing a pile truss structure of an offshore wind power full-rotation multi-angle pile driver according to claim 5, characterized in that: The straightness detection requirements of the second main U tube are: Overall dimensions: the allowable deviation of length is ±3mm, the allowable deviation of width is ±2mm, the allowable deviation of height is ±3mm, and the allowable deviation of distortion is ±3mm; Horizontal and vertical straightness: the allowable deviation is 2mm every 5 meters, and the overall allowable deviation is ≤3mm; The straightness detection requirements of the first main U tube are: The horizontal deviation of the extended end face is: ±1mm for every 3m; ±1.5mm for every 5m; The vertical deviation of the extended end face is: the allowable deviation is ±3mm every 3m; the allowable deviation is ±5mm every 5m.

7. The method for manufacturing a pile truss structure of an offshore wind power full-rotation multi-angle pile driver according to claim 1, characterized in that: The pile frame section I includes pile frame section I-1 and pile frame section I-2. Pile frame section I-1 and pile frame section I-2 are integrally manufactured in a workshop and fixed together with card codes. After the overall manufacturing is completed, they are divided into sections in the workshop, and the closing inspection marking lines are made at the same time, and then they are separated out of the workshop.

8. The method for manufacturing a pile truss structure of an offshore wind power full-rotation multi-angle pile driver according to claim 1, characterized in that: Steps for preparing two bottom sealing plates at one time: First, a rectangular structure is made of a plate, and then a pentagonal structure is made of a plate. The first pentagonal structure, the first rectangular structure, the second rectangular structure and the second pentagonal structure are tightly placed on the tire frame in sequence and then clamped. The first pentagonal structure and the first rectangular structure as well as the second rectangular structure and the second pentagonal structure are welded tightly to form two tightly arranged structural plates. The structural plates include a first vertical section, a first horizontal section, an inclined section, a second horizontal section, a second vertical section and a third horizontal section arranged in sequence, and there is an obtuse angle between the inclined section and the first horizontal section. The above two structural plates are turned over and fixed to form the bottom sealing plate shown.
