Wherein, all have on two flanges for the grout hole and the weep hole that are in the milk.Be provided with reinforcing rib between flange on the spud leg and the spud leg, be provided with reinforcing rib between the flange of marine pile and the marine pile.
Two of embodiment connects by the locking of one group of bolt between the brace group, is positioned at upper flange with the spud leg excircle is connected as a single entity, the brace group below being positioned at along marine pile top end opening circle distribution and with marine pile be one.
Wherein, be provided with reinforcing rib between the flange on the spud leg and the spud leg, be provided with reinforcing rib between the brace of marine pile and the marine pile.
A kind of for the basic location structure that grouting is installed of offshore wind turbine jacket as mentioned above, it is characterized in that the bolt hole on the described spud leg upper flange is radially or circumferential elongated hole, the bolt hole on described marine pile upper flange or the brace for the spud leg upper flange on bolt hole one next submit the wrong circumferentially or radially elongated hole that arranges.
A kind of location structure for the installation grouting of offshore wind turbine jacket basis is characterized in that described marine pile has standby grout hole as mentioned above.
The present invention has following advantage and effect with respect to prior art:
1, adopt bolt with spud leg upper flange and marine pile flange or brace locking, then blower foundation and marine pile are connected as a single entity, be beneficial to blower foundation opposing gravitational load, wind load and wave load make finishing smoothly of the follow-up installation process grouting of blower foundation, and guarantee the bonding strength that is in the milk, guarantee the stability of blower foundation, need not after grouting is finished bolt, flange dismounting, so cost is low, easy to operate, the activity duration is few.
2, each spud leg upper flange all has for the grout hole and the weep hole that are in the milk with the top flange of its corresponding marine pile; Have standby grout hole in marine pile one side, convenient grouting is carried out smoothly.
3, need not after grouting is finished bolt, flange dismounting, so cost is low, easy to operate, the activity duration is few, is conducive to the present invention and extensively promotes the use of.
4, spud leg upper flange and marine pile flange or brace bolt hole be respectively one next submit the wrong elongated hole of radially offering with circumferencial direction that arranges, to solve because install, bolt grout hole alignment issues that test or welding error wait to bring.
