Detailed Description

The present invention will be further illustrated by the following specific examples, which are carried out on the premise of the technical scheme of the present invention, and it should be understood that these examples are only for illustrating the present invention and are not intended to limit the scope of the present invention.

As shown in fig. 1 and 2, a wind power installation vessel spud leg, including spud leg body 1, spud leg body 1 is hollow column, and from the top down is equipped with multiunit bolt hole 11 on spud leg body 1, and every 4 bolt holes 11 are a set of, and the height in every bolt hole 11 of group equals, and evenly distributed is in spud leg body 1's circumference, and 4 bolt holes 11 symmetry set up, make things convenient for hydraulic lifting device's bolt to insert from four directions, and load balancing. Each bolt hole 11 is provided with a reinforcing sleeve 2, the outer diameter of each reinforcing sleeve 2 is the same as the diameter of the bolt hole 11, the reinforcing sleeves 2 are inserted into the bolt holes 11, and the reinforcing sleeves 2 are connected with the pile leg body 1 in a welding mode. Through the reinforcing sleeve 2, when the bolt is inserted into the bolt hole 11, the load is averaged through the reinforcing sleeve 2, and the local pressure caused by small contact area of the bolt and the pile leg body 1 is prevented from being overlarge.
