Abstract

The invention relates to a pile stabilizing frame for pile sinking of an offshore wind power batter pile group and a pile sinking method. The pile stabilizing frame comprises a supporting frame, a first limiting frame and a second limiting frame; the first limiting frame and the second limiting frame are arranged at two opposite ends of the supporting frame correspondingly; rotatable first batter pile positioning mechanisms are arranged on the first limiting frame; a plurality of second batter pile positioning mechanisms are arranged on the second limiting frame; and on a horizontal plane, the projection area of the first limiting frame is smaller than or equal to the projection area of the second limiting frame. According to the pile stabilizing frame, fixing and inclination adjusting of a plurality of batter piles can be achieved, the batter piles do not need to be hoisted by moving ship position for multiple times, on the one hand, the safety risk is reduced, on the other hand, the working procedures can be reduced, the pile sinking efficiency is improved, and then the installation cost is saved. The rotatable second batter pile positioning mechanisms are arranged to be matched with the plurality of first batter pile positioning mechanisms, so that the overall weight of equipment can be reduced, the production and installation difficulty is reduced, and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of offshore piling construction, in particular to a pile stabilization frame and a pile driving method for pile driving of inclined pile groups of offshore wind power. Background technique [0002] In the 21st century, offshore wind power has become an important strategic energy source. More and more countries have begun to vigorously build wind farms. A large part of the wind farms are located in the intertidal zone. Intertidal zone construction is an important research for offshore wind power project construction. one of the objects. Pile foundation construction is one of the key contents of offshore wind power projects, and its water depth and geological conditions directly affect the selection of pile driving technology. At the same time, inclined pile groups with high bearing capacity and good stability are mostly used in the pile foundation construction of offshore wind power pile groups. [0003] Wi...
