The invention discloses a method for accurately positioning a ship single shell block on a wharf. The method comprises the following steps that firstly, before the single shell block is hoisted, a jacking bracket is fixedly installed on the back face of an inclined side plate; secondly, a manhole is formed in the transverse bulkhead of the original ship; thirdly, jacking lower cross beam installation lines are drawn on the double-layer bottom and the broadside platform of the original ship correspondingly; 4, lifting the jacking lower cross beam from the large hatch and placing the jacking lower cross beam in place according to the mounting line; fifthly, a jacking device is placed on the jacking lower cross beam; sixthly, the single-shell block is hoisted into the large cabin; seventhly, a jacking upper cross beam at the double-layer bottom is moved in from a manhole of the transverse bulkhead; and 8, the floating crane is used for adjusting the single shell block in place, the single shell block is arranged on the jacking upper cross beam, and the jacking device is used for adjusting the position of the single shell block. The cross beam is in contact with the ship body structure, so that the deformation of the structure can be greatly reduced, and the subsequent field workload is reduced.

    本发明公开了一种船舶单壳体总段在码头精确定位方法,包括以下步骤:步骤一、单壳体总段吊装前将顶升牛腿固定安装于斜旁板反面上;步骤二、在原船的横舱壁上开人孔;步骤三、在原船的双层底及舷侧平台上分别划顶升下横梁安装线;步骤四、将顶升下横梁从大舱口吊入并按照安装线放置到位;步骤五、将顶升装置放置到顶升下横梁上;步骤六、将单壳体总段吊入到大舱内;步骤七、将双层底处的顶升上横梁从横舱壁的人孔移入;步骤八、利用浮吊将单壳体总段调整到位,将单壳体总段落在顶升上横梁上,利用顶升装置调整单壳体总段的位置。本发明采用横梁与船体结构接触,可大大减少结构的变形,减少后续的现场工作量。
