還有一個值得注意的問題是在立交橋匝道上放線定位。
Another noteworthy problem is setting out and positioning on the ramp of overpass.
立柱間距實際尺寸要做到內(nèi)收外放,但收和放的尺寸不要超過5mm。
The actual size of the column spacing should be inward and outward, but the dimension should not exceed 5mm.

Because the slab is straight and the spacing is curved on the curb.
間距尺寸放和收之后,護欄板在安裝時變得容易,而且線形美觀平順。
After the spacing size is put and closed, the guardrail board becomes easy to install, and the line shape is beautiful and smooth.
