DESCRIPTION
Hollow self-drilling anchors are mainly used for supporting soft soil layers with difficult pre-forming holes. In actual application, the rod body of the drill bit is connected to the rig, and can be directly drilled into the soil layer without pre-forming holes; multiple rod bodies are connected by special connectors, and the soil layer is driven into the soil layer by section until the required length is reached.
