在打桩机导杆上记录下桩锤的位置，以后每打一根立柱。

Record the position of the pile hammer on the guide rod of the pile driver, and then drive each column.

当桩锤下落到记下的位置时就说明立柱已经打到位了。

When the hammer falls to the recorded position, the column is in place.

这样路缘石顶面的不平顺就反映到立柱顶面，使得护栏板整体不平顺。

In this way, the irregularity of the top surface of the curb will be reflected to the top surface of the column, which will eventually make the overall irregularity of the guardrail board.
