The invention belongs to the technical field of overwater operation, and discloses a method for hoisting an ultra-large steel pile of a cutter suction dredger. Comprising the following steps that S1, a steel pile and a floating crane are provided on the operation site of the cutter suction dredger, the steel pile comprises a cylinder and a pointed cone which are coaxially connected, a hanging part is arranged at the end, away from the pointed cone, of the cylinder, the floating crane is moored, and a lifting mechanism of the floating crane is connected to the hanging part; s2, second lifting equipment and a binding rope are provided, the pointed cone is tightly sleeved with the binding rope, and a lifting mechanism of the second lifting equipment is connected with the binding rope; s3, the floating crane lifts the hanging end of the steel pile firstly, second lifting equipment lifts the pointed cone end of the steel pile in a matched mode, and the hanging end of the steel pile is always kept higher than the pointed cone end of the steel pile till the steel pile is stabilized in the vertical state; s4, the binding rope is unloaded, and the position of the steel pile is adjusted to the position above the center of a hoop of the cutter suction dredger; and S5, the steel pile is put down to be inserted into the water bottom, and connection between the floating crane and the hanging part is removed.

    本发明属于水上作业技术领域,公开了一种绞吸挖泥船超大型钢桩吊装方法。包括以下步骤:S1、在绞吸挖泥船的作业现场,提供钢桩和浮吊,钢桩包括同轴相连的圆柱体和尖锥,圆柱体远离尖锥的一端设有吊挂部,将浮吊停泊,将浮吊的起升机构连接在吊挂部上;S2、提供第二起吊设备和绑扎绳,将绑扎绳紧套在尖锥上,第二起吊设备的起升机构与绑扎绳相连;S3、浮吊先抬升钢桩的吊挂端,第二起吊设备配合吊起钢桩的尖锥端,并始终保持钢桩的吊挂端高于钢桩的尖锥端,直至钢桩稳定在竖直状态;S4、卸下绑扎绳,调整钢桩的位置至绞吸挖泥船的抱箍中心上方;S5、下放钢桩插入水底,解除浮吊与吊挂部的连接。
