In the demanding field of geotechnical engineering, projects often face challenges such as unstable slopes, soft rock conditions, and the need for rapid support in tunneling operations. A recent large-scale infrastructure development in Europe, involving a tunnel through mountainous terrain with complex geological strata, highlighted the necessity for reliable and efficient reinforcement solutions. SupAnchor, a leader in geotechnical products, has stepped in with its SupFRP® GFRP Hollow Injection Bolt, a core component of its SupFRP® series, designed to address these exact challenges. This innovative product integrates rock bolting and injection functions, ensuring that after grouting, the bolt remains in place to bear load alongside plates and nuts, thereby enhancing project durability and safety.
This construction image illustrates the practical application of SupAnchor's systems in real-world scenarios, demonstrating how the self drilling anchor system is deployed to stabilize challenging sites. The GFRP hollow injection bolt, with its lightweight design and high performance, is revolutionizing how engineers approach geotechnical reinforcement, making it a key tool in modern infrastructure projects.
The SupFRP® GFRP Hollow Injection Bolt is engineered for high tensile load and pressure resistance, making it suitable for a wide range of applications. During installation, the bolt is drilled into the borehole, and grouting material is injected under high pressure to ensure full coverage and strong bonding. This process addresses common engineering needs such as improving load-bearing capacity and preventing corrosion in harsh environments. Key parameters that set this product apart include its guaranteed tensile load, which ranges from 220 kN to 490 kN across models, and its pressure resistance up to 30 MPa, allowing it to withstand significant stresses. Additionally, the hollow bar anchor design facilitates easy injection and cuttability, while its corrosion resistance extends service life in permanent applications.
To better understand the specifications, here is a summary table of selected 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 |
These technical features enable the self drilling anchor bolt to solve critical challenges, such as providing reliable support in confined ground conditions or during TBM face operations, where quick installation and high strength are paramount. The product's adaptability, with options for left or right-hand threads and lengths from 2 to 11 meters, ensures it meets diverse project requirements.
The GFRP hollow injection bolt finds extensive use in various geotechnical applications, significantly impacting global infrastructure safety. Key scenarios include:
