In response to growing demands for safer and more efficient geotechnical solutions, SupAnchor has introduced the GFRP Hollow Injection Bolt, a core product of its SupFRP series. This innovation addresses critical challenges in projects such as slope stabilization and tunneling, where unstable geological conditions and high-pressure environments require robust reinforcement systems. The bolt combines drilling and grouting functions, allowing it to remain in boreholes post-injection to bear loads alongside plates and nuts, thereby improving project quality and durability.
The SupAnchor GFRP Hollow Injection Bolt is designed with high tensile load and pressure resistance, making it suitable for a wide range of geotechnical applications. Key technical features include guaranteed tensile loads up to 490 kN, pressure resistance up to 30 MPa, and low weight for easy handling. These specs enable the bolt to solve engineering challenges by providing reliable support in confined ground conditions and soft rock stabilization. The following table summarizes the technical data for the available models:
| Model | Outside Diameter (mm) | Guaranteed Tensile Load (kN) | Pressure Resistance (MPa) | Weight (kg/m) |
|---|---|---|---|---|
| H25/220 | 25 | 220 | 5 | 0.64 |
| H28/320 | 28 | 320 | 5 | 0.88 |
| H32/360 | 32 | 360 | 5 | 1.20 |
| H38/490 | 38 | 490 | 5 | 1.5 |
| H22/230 | 22 | 230 | 18 | 0.58 |
| H25/300 | 25 | 300 | 30 | 0.79 |
The bolt's high corrosion resistance and good bond force with grouting materials ensure long-term performance, while its cuttability allows for flexibility in installation. This makes the self drilling anchor bolt a versatile choice for engineers facing diverse site conditions.
The SupAnchor GFRP Hollow Injection Bolt is widely applicable in various geotechnical engineering projects. Key applications include slope stabilization, where it prevents landslides and erosion; TBM face support for tunneling operations; forepoling in excavation sites; and stabilization of soft rock in mining and construction. Its ability to handle high injection pressure enables full grouting, which enhances structural integrity and project quality. For instance, in confined ground conditions, the hollow bar anchor provides reliable reinforcement without adding excessive weight, improving safety and efficiency.
This geotechnical reinforcement system is designed to meet the rigorous demands of modern engineering, offering a drill-and-grout bolt solution that integrates seamlessly into existing workflows.
