在后来的施工中，我们找到了一种既简单又能保证护栏板线形的方法。

In the later construction, we found a simple and linear method to ensure the guardrail plate.

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 crosshairs of each column POSTTTION with a level gauge.

（不需水准点，只测相对标高），根据这些数据计算出坡度。

(no benchmark is needed, only relative elevation is measured), and the slope is calculated based on these data.

这样既保证了立柱顶面高度的平顺，又能使立柱顶距路缘石顶高度误差很小。

In this way, the height of the column top is smooth and the height error between the column top and the curb top is small.
