立柱纵向位置的确定：先在路缘石上用红铅笔根据立柱间距划出横线，再用线绳和钉子顺路方向上放出一条线，反复调整线形，

Determination of the vertical position of the column: first draw a horizontal line on the curb with a red pencil according to the column spacing, then set out a line along the road direction with a rope and nail, and adjust the alignment repeatedly.

然后用红铅笔在这条线上划出与横线垂直的纵线，形成十字线，

Then use a red pencil to draw a vertical line perpendicular to the horizontal line to form a cross line.

在打入立柱时，严格按立柱距十字线中心距离打入，

When driving the column, the distance between the column and the center of the cross line shall be strictly followed.

这样就保证了立柱在纵向上的顺直度。

This ensures the vertical straightness of the column.
