Due to its special material, it is suitable for mine tunnel construction and will gradually replace traditional metal anchor rods. It is also called glass fiber anchor rod or glass fiber reinforced plastic anchor rod.

[0003] After the glass fiber anchor rod is inserted into the drill hole, a part of it tends to extend out. The excess part sometimes affects the subsequent operation in actual construction. At this time, the anchor rod needs to be cut. Since the glass fiber anchor rod is in the shape of a threaded rod as a whole, it is slightly inconvenient to cut. Therefore, a glass fiber reinforced anchor rod is needed. A ring groove can be preset on the surface of the anchor rod, and the ring groove is wrapped and protected by a metal belt to avoid the ring groove from breaking due to its small diameter during transportation, thereby improving the excellent performance of the glass fiber anchor rod in being easy to cut and preventing itself from breaking.
