Scope

Main technical content: The detection technology of the embedding depth of wave-shaped beam guardrail posts by drilling method is to use a dedicated drilling measurement tool to drill holes directly in the lumen of the wave-shaped beam guardrail posts, remove the soil in the lumen, and then use a dedicated test hook rod to directly measure the embedding depth of the posts. This detection method is reliable and accurate, with a short time consumption and high efficiency. This technical specification stipulates the instruments, detection steps, detection reports, and record forms for the detection of the embedding depth of wave-shaped beam guardrail posts, providing a standard method for self-inspection and quality inspection evaluation by construction units.
