The invention discloses a construction tolerance matching method for butt joint positions of a lower structure and an upper module of an ocean platform. The construction tolerance matching method for the butt joint positions of the lower structure and the upper module of the ocean platform comprises the following steps that S1, construction tolerance requirements of the lower structure and the upper module are determined; s2, an annular plate at the butt joint position of the upper module is holed, and the size of a hole is slightly smaller than the diameter of a stand column; s3, before the stand columns are inserted, dimension data of the butt joint positions of the upper module and the lower structure are obtained through measurement; s4, comparing and adjusting the size data of the lower structure and the theoretical position of the upper block stand column; s5, according to the relative relation determined in the step S4, determining the position of the upper module inserted with the stand column, and reaming according to the size of the stand column; and S6, block stand columns are inserted, so that the butt joint positions of the lower structure and the upper block are accurately matched. According to the construction tolerance matching method for the butt joint positions of the lower structure and the upper module of the ocean platform, accurate matching of the butt joint positions is achieved, and the strength of the butt joint positions is reduced.
本发明公开了一种海洋平台下部结构与上部组块对接位置建造公差匹配方法,该海洋平台下部结构与上部组块对接位置建造公差匹配方法包括以下步骤:S1、确定下部结构及上部组块的建造公差要求;S2、上部组块对接位置环板开洞,洞口尺寸略小于立柱直径;S3、立柱插入前,分别测量得到上部组块及下部结构对接位置的尺寸数据;S4、将下部结构尺寸数据与上部组块立柱理论位置进行比对调整;S5、根据S4确定的相对关系确定上部组块插立柱的位置,按照立柱尺寸进行扩孔;S6、插入组块立柱,使得下部结构与上部组块对接位置精确匹配。本发明提供的海洋平台下部结构与上部组块对接位置建造公差匹配方法,实现对接位置的精准匹配,降低对接位置强度。
