Offshore wind power pile sinking construction process assisted by pile stabilizing and positioning ship
The invention provides an offshore wind power pile sinking construction process assisted by a pile stabilizing and positioning ship, which comprises the following steps: the pile stabilizing and positioning ship sails to a construction area in a channel to complete anchoring; the pile stabilizing and positioning ship adjusts the direction to coincide the design coordinates of the center of the stern pile embracing ring and the center of the steel pipe pile, and positioning is completed; carrying out entry point anchoring on the crane ship, and completing the positioning of the crane ship when the anchoring position is parallel to the longitudinal central axis of the pitching ship relative to the longitudinal central axis of the crane ship; the supporting piles on the deck of the pile stabilizing and positioning ship are hoisted through a crane ship, the four supporting piles are inserted into a pile gripper, and the piles are sunk to the designed elevation through a vibratory hammer; the fixed connection between the corbel of the pile gripper and the deck supporting seat of the pile stabilizing and positioning ship is relieved; the crane ship lifts the whole pile gripper, so that the pile gripper leaves the ship body; the pile gripper platform is placed on the supporting piles through the suspension system, and after leveling, the pile gripper and the supporting piles are locked to form an offshore pile gripper platform; and a crane ship is used for single-pile sinking.
本发明提供了利用稳桩定位船辅助进行的海上风电沉桩施工工艺，包括以下步骤：稳桩定位船航道航行到施工区域，完成抛锚；稳桩定位船调整方位，使船尾抱桩环中心与钢管桩中心设计坐标重合，完成定位；起重船进点抛锚，抛锚位置相对于在至其纵向中心轴线与插桩船纵向中心轴线平行时，起重船定位完成；利用起重船起吊稳桩定位船甲板上的支撑桩，将四根支撑桩插入抱桩器，利用振动锤沉桩至设计标高；解除抱桩器牛腿与稳桩定位船甲板支撑座的固定连接；起重船将抱桩器整体提升，使抱桩器离开船体；通过悬挂系统将抱桩器平台安放于所述支撑桩上，调平后抱桩器与支撑桩锁定，与其形成海上抱桩器平台；利用起重船进行单桩沉桩。
