Surface treatment: Use a grinding tool to grind the ground anchor rod (1), the first spiral blade (2), the second spiral blade (3) and the pointed head (10) to remove excess burrs, smoothen them for easy assembly and application, grind the pointed head (10) to make it sharper, grind the side edges of the first spiral blade (2) and the second spiral blade (3), and obtain cutting edges (13) for the first spiral blade (2) and the second spiral blade (3). Finally, the ground anchor rod (1), The first spiral blade (2), the second spiral blade (3) and the pointed head (10) are cleaned and dried. Spray anti-corrosion paint as needed.
