摘要
永久中立柱是地下主体结构柱骨架的一部分,其定位的准确性直接影响到整体结构的质量,因此,永久中立柱位置必须准确。由于永久中立柱较长,断面尺寸大,吊装、稳固困难,为保证定位准确,采用专用定位架进行定位。
The permanent middle columns are the important skeletons of the main structures of subway station, the accuracy of the posi- tion of permanent middle columns has great influence on the construction quality of the main structures.The characteristics of perma- nent middle columns, such as great length ,large cross section, difficulty during their lifting and stability are considered in this paper.A special position shelf has been developed and adopted to ensure the accuracy of the position of permanent middle columns.
