图解法放样输电杆塔的拉线

介绍一种杆塔拉线的放样方法。它是根据规程允许拉线对地面夹角误差及拉线在杆塔绞结处对地面高度按一定比例画成图 ,使用时对照经纬仪所测的视距和仰角 (俯角 ) ,参照所作的图 ,便可以确定被测点是否是拉线的入土点 ,同时可以直接量取拉线的长度。此法比传统拉线放样法减少了许多计算量 ,且简单、明了。

Transmitting the Pulling Wire of the Pole Tower with Illustration

This article mainly introduces the method of pulling wires with pole tower. According to the role, it allows the error of the angle between the pulling wires and the ground. Besides this, we can complete drawing depending on the proportion of the height between the crossing and the ground. Comparing with the seeing distance and the cape of bow as well as the drawing, we may use it to decide whether the point measured is just the point buried. At the same time, we can directly measure the length of the pulling wire. Compared with the traditional method, this method is simple and clear.
