高层建筑滑模施工垂直度的监控测量

The supervision surveying of verticality in slipform contraction of tall building

由于滑模施工机械化程度高,施工速度快,近年来在一些高层建筑施工中被推广应用,但目前监测预控滑模施工建筑物的垂直度方法仍在探讨中。本文介绍江苏省人民银行公寓大楼在滑模施工中采用布设逐段升高的“之”形控制点来监测事先在滑模提升架上特制的观察点(台),用全站仪坐标法测定竖向偏差,结果使全高滑模施工误差小于规定的精度要求。

Because of the high mechanizing and speed of slipform construction, It is popularized to be used in construction of some tall buildings. But the method of supervision surveying of verticality is still studied, here introduces a method which is used in the people bank apartment of Jiangsu province. That is establishing some control points in the shape of 'Z' Section by section with the height to supervise the observation point (table) which is made especially on slipform shift inadvance, then measuring the vertical offset with total station electronic tacheometer and making the slipform error of total height less than the precision reqairemont.
