In the challenging terrains of European tunneling and North American slope stabilization projects, engineers often grapple with soft rock and clay soil conditions that demand rapid, reliable ground support. The SupAnchor® GFRP SDA Bolt emerges as a cutting-edge solution, designed to streamline construction processes and enhance safety. This innovative product integrates drilling, grouting, and anchoring into a single operation, enabling fast installation and robust reinforcement. With applications ranging from face stabilization in tunnels to slope support, the self-drilling anchor system addresses critical engineering needs in infrastructure development.
The SupAnchor® GFRP SDA Bolt offers unparalleled efficiency on-site, thanks to its central hole that allows for water flushing during drilling and seamless anchor grouting. This feature is particularly beneficial in soft rock or clay soil, where traditional methods may falter. Key technical parameters, such as high tensile strength and torsion resistance, ensure durability and performance. For instance, the bolt's guaranteed tensile load ranges from 220 kN to 490 kN across models, providing reliable end loading for various geological challenges. Additionally, its cuttability protects machinery during tunnel drifting, reducing downtime and costs.
