首先用水准仪对每一个立柱位置的十字线进行水准测量。

First, level the cross line of each column POSTTTION with a level.

（不需水准点，只测相对标高），根据这些数据计算出坡度。

According to these data, the slope can be calculated.

这样既保证了立柱顶面高度的平顺。

In this way, the height of the top of the column is smooth.

又能使立柱顶距路缘石顶高度误差很小。

And the height error between the top of column and the top of curb is very small.

这样就保证了立柱在纵向上的顺直度。

This ensures the straightness of the column in the longitudinal direction.

也将成为城市道路上的一道亮丽的风景线。

It will also become a beautiful landscape on the city road.
