摘要
采用测量控制的方法来检测调整型钢柱的施工安装.用导线测量以及外控与内控相结合的方法建立平面测量控制网,为高精度细部放样打好基础;采用附合水准路线建立高程控制网.依据控制网和设计轴线建立平面控制格网,在轴线延长线上设立控制点.用两台经纬仪分别架设在引出轴线上,结合水准仪对型钢柱进行测量校正,保证其轴线位置、竖直度及柱顶标高符合设计和规范要求.
Survey control technique is used to check and correct the costruction of profile steel pillar in this article. Horizontal control network is first built with traverse survey and the combination of intercontrol and extra-control, which put the way for precise detail loft. Vertical control network is done with the annexed leveling line. Horizontal control grid is built according to the network and design axis and control points are designed on the extended line of axis. Two theodolites are placed on the extended line of axis with the level to check and correct the profile steel pillar and assure the axis position, vertical direction and pillar elevation agree with the design and caritas.
