Dismantling method for offshore wind power steel pipe pile
The invention discloses a dismantling method for an offshore wind power steel pipe pile. The dismantling method comprises the following steps that firstly, a ship engine enters a point for anchoring; secondly, two temporary lifting lugs are installed on the pile top flange; thirdly, an inner platform plate in the steel pipe pile is dismantled; fourthly, mud is sucked in the pile; fifthly, the pile cutting device is placed; 6, hanging and buckling the steel pipe piles; seventhly, the pile cutting device is lowered to the pile cutting position and stably positioned; 8, pile cutting operation is conducted; ninthly, the pile cutting device is lifted to the pile top and stably positioned; tenthly, the cut steel pipe piles are hoisted; eleventhly, tailing of the cut steel pipe pile is conducted; twelfthly, the cut steel pipe piles are subjected to barge falling; (13) the pile cutting device is pulled out from the interior of the cut steel pipe pile; and step 14, withdrawing the ship engine. According to the dismantling method, various risks confronted by manual underwater pile cutting operation are avoided, and therefore the dismantling efficiency of the waste offshore wind power steel pipe pile is greatly improved.
本发明公开了一种海上风电钢管桩的拆除方法，包括以下步骤：步骤一，船机进点抛锚；步骤二，在桩顶法兰上安装两个临时吊耳；步骤三，拆除钢管桩内的内平台板；步骤四，桩内吸泥；步骤五，割桩装置安放；步骤六，钢管桩挂扣；步骤七，割桩装置下放至割桩位置并稳固定位；步骤八，割桩作业；步骤九，割桩装置提升至桩顶并稳固定位；步骤十，起吊切割下的钢管桩；步骤十一，切割下的钢管桩溜尾；步骤十二，切割下的钢管桩落驳；步骤十三，从切割下的钢管桩的内部拉出割桩装置；步骤十四，船机撤点。本发明的拆除方法避免了人工水下割桩作业面临的各种风险，从而大大提高了废置海上风电钢管桩的拆除效率。
