还有一个值得注意的问题是在立交桥匝道上放线定位。

Another noteworthy problem is setting out and positioning on the ramp of overpass.

立柱间距实际尺寸要做到内收外放，但收和放的尺寸不要超过5mm。

The actual size of the column spacing should be inward and outward, but the dimension should not exceed 5mm.

因为板是直的，而间距在路缘石上是曲线。

Because the slab is straight and the spacing is curved on the curb.

间距尺寸放和收之后，护栏板在安装时变得容易，而且线形美观平顺。

After the spacing size is put and closed, the guardrail board becomes easy to install, and the line shape is beautiful and smooth.
