Underwater installation method for large-size anchor pile
The invention discloses an underwater installation method for a large-size anchor pile. The method comprises the steps that S1, a transportation barge loads the anchor pile to sail to an operation sea area; S2, the transportation barge berths the workboat, and a workboat crane hoists the anchor piles in a horizontal hoisting mode; S3, a workboat crane is lowered, the weight of the anchor pile is gradually transmitted to an anchor pile hanging platform of the workboat from the workboat crane, and underwater pile turning operation of the anchor pile is conducted; S4, the workboat crane is connected with the anchor pile hanging rigging on the anchor pile hanging platform; S5, the anchor pile is hoisted by the workboat crane, the weight of the anchor pile is transferred to the workboat crane from the anchor pile suspension platform, and the anchor pile is vertically hoisted and lowered to the preset water depth; S6, the ROV adjusts the heading direction of the anchor pile underwater, and pile inserting operation of the anchor pile is conducted; and S7, the anchor pile automatically settles by means of the self weight. A conventional DP workboat can replace a large crane ship to complete hoisting, lowering and pile inserting operation of a large-size anchor pile, and the offshore construction operation cost can be greatly reduced.
本发明公开一种大尺寸锚桩水下安装方法，包括：S1：运输驳船装载锚桩航行至作业海域；S2：运输驳船靠泊作业船，作业船吊机采用水平吊装的方式进行锚桩的起吊作业；S3：下放作业船吊机，将锚桩重量从作业船吊机逐步传递到作业船的锚桩悬挂平台，进行锚桩的水下翻桩作业；S4：作业船吊机连接锚桩悬挂平台上的锚桩悬挂索具；S5：作业船吊机起吊锚桩，将锚桩重量由锚桩悬挂平台传递转移至作业船吊机，将锚桩垂直吊装下放至预定水深；S6：ROV在水下调整锚桩艏向，进行锚桩的插桩作业；S7：锚桩依靠自身重量进行自行沉降。其可实现由常规DP作业船替代大型起重船完成大尺寸锚桩的吊装下放与插桩作业，可极大地降低海上施工作业成本。
