投影法地面划印施工及误差分析

投影法地面划印是用现场测量代替传统地面划印法中的部分计算过程,实体现场地面划印清除了基础、杆塔施工造成的误差等因素,使地面划印施工中需要计算的划印差值得以简化,使一般技术工人容易掌握计算和操作,同时又提高了架线的速度和弛度的精度。

A Ground Construction Method by Means of the Projection Marking and Its Error Analysis

Using the ground construction method by means of the projection marking, a parts of calculation process of traditional ground marking construction method would be replaced by the measurement in site, and some factors which cause some errors in entity ground markingconstruction would be eliminated, so that the marking difference that shouldbecalculated in ground marking construction could be predigested, its calculation and operation would be held by normal skilled workers, and the constructingspeedand the precision of laxityoftransmissionlinealsocouldbeenhanced.
