电厂间冷塔X支柱测量控制

Indirect Cooling Tower X Pillar Control Measure in Power Plants

X支柱测量控制作为电厂测量重点和难点,主要采用钢尺量距、铅锤仪投点、全站仪放样等测量方法。先在X支柱下方垫层平面上测设X支柱投影线,然后利用铅锤仪、钢卷尺将投影点引至相应标高处,用钢丝连接0.00m和29.86m处定位线,即得出X支柱模板控制线。X支柱标高、半径复核采用全站仪三维坐标测量和曲线测量。

X measurement and control as a key pillar of power measurement,mainly adopts steel tape distance,plumb instrument investment,Totalstation lofting measurement method. The first set of X projection line in the X pillar pillar under the cushion,and then use a meter steel tape will lead to the corresponding projection point elevation,joint positioning line0 meters and 29. 86 meters of wire,which obtains the X pillar template control line; X pillar elevation,latitude total station3 D coordinate measurement and curve radius was measured by the review.
