B, piling; Pile tube 4 is correspondingly inserted from each root jacket leg 2, and make pile tube 4 lower ends stretch out jacket leg 2, thereby get into sea bed; Utilize pile driver to squeeze into pile tube 4 in the sea bed afterwards and make pile tube 4 place sea bed securely, jacket leg 2 parts are then exposed in pile tube 4 upper ends;
C, grouting, accomplish fluently pile tube after, can leave the gap between pile tube and the jacket leg 2, pour into cement mortar between the gap, and make cement mortar flow into the bottom of jacket leg 2 and be fixed on the sea bed, and the gap between pile tube and the jacket leg 2 also can be filled.
Aforesaid offshore wind turbine jacket basis mounting method; It is characterized in that also including the installation jacket platform, after the B step, each root canal pile 4 upper end exposed the 2 a part of concordant cut-outs of jacket leg after; Make the upper end of each root canal pile 4 be in same horizontal plane; Again jacket platform 5 is weldingly fixed on each root canal pile 4 afterwards, jacket platform 5 is horizontal, carry out grouting step afterwards again.
Aforesaid offshore wind turbine jacket basis mounting method is characterized in that being provided with dashboard 7 in each root jacket leg 2 bottom.
The present invention compared with prior art has following advantage:
Device of the present invention utilizes a conduit support body, earlier it is placed on the sea bed, inserts pile tube in the jacket leg more afterwards and stretches out from jacket leg bottom and enter into sea bed, utilize afterwards pile driver with pile tube get to realize in the sea bed fixing.
Because the location of jacket leg is arranged, so the location of pile tube very accurately, jacket platform can be by the piling bar leveling of squeezing into simultaneously.
And method of the present invention has been utilized the jacket device, thereby makes this offshore wind turbine jacket basis mounting method have that result of use is good, the location is easy, simple to operate, efficient, low cost and other advantages are installed.
