What should be noted when constructing with a highway guardrail drilling and piling integrated machine?

a) During the construction process of the highway guardrail drilling and piling integrated machine, it is essential to accurately grasp the information of various facilities, especially the exact location of various pipelines buried in the roadbed. Damage to underground facilities is not allowed during construction. If the depth of underground communication pipelines, drainage pipes, or culverts is insufficient, the position of the chromatography column should be adjusted or the method of fixing the chromatography column should be changed.

b) Do not pull out the chromatography column for calibration if it is driven too deep. The remaining parts should be pulled out, the foundation should be re-compacted, and then the position of the column should be adjusted.

c) Flanges should be installed on bridge flanges, paying attention to the position of the flange and the control of the elevation of the opposing column's top surface.
