A self-drilling rock bolt that pursues improved workability and thorough cost-effectiveness!
The "SP Anchor" is a self-drilling rock bolt that can be used as a locking bolt with the drilling rod as is, particularly in unstable ground such as unsupported rock walls or steep slopes, where improved workability is desired. Rock bolts are widely used in tunnel support work in mountainous areas and slope reinforcement earthworks. Various types of grouting agents, such as cement-based and polyurethane-based, can be selected. Please feel free to contact us when needed. 【Features】 ■ No need for double pipes, making the drilling machine compact and easy to move, suitable for narrow workspaces. ■ Drilling, rod insertion, and grouting can be completed in one process, making it economical. ■ Can handle various strata with the same operation, eliminating the need for additional geological testing. ■ The series of operations is simple and does not require highly skilled workers. ■ It is a fully threaded steel rod, and by connecting with couplers, it can accommodate any length. ■ Various types of grouting agents, such as cement-based and polyurethane-based, can be selected. *For more details, please download the PDF or feel free to contact us.
