Tubular Bolt AnchorThe advantages mainly include:
1. Enhanced Support Effectiveness: The pipe-shaped anchor bolt is widely used in the support of various tunnels, offering superior support compared to other methods. It is particularly popular during coal mining operations.
2. Cost-effective Support: The tube-type anchor rod saves costs on materials, particularly in steel savings, which is usually over 50% and can even reach 70% in some comparisons, making it more cost-effective than other anchor rods.
3. Low Labor Intensity: The pipe groove anchor bolts are lightweight, with individual weights generally under 5kg, significantly reducing the labor intensity for workers.
4. Easy Operation: The installation of the tubular anchor bolt is extremely simple, requiring no complex tools or technology, significantly enhancing construction efficiency.
5. Strong Anchoring Force: The tubular bolt anchors boast a strong anchoring power, effectively securing the surrounding rock.
However, there are also some drawbacks to tubular bolt anchors:
Not suitable for soft rock and soil: As the bolt requires anchoring in hard rock, it is not suitable for environments with soft rock and soil.
2. High Construction Standards: Due to the precise installation requirements of pipe gap anchor rods, improper construction can lead to the failure of the anchors.
3. Limitations: The application scope of pipe bolt anchors is somewhat limited, such as for structures with larger spans, their load-bearing capacity may be restricted.
4. Significant Impact on Installation Quality: Poor installation quality may affect the anchoring effect and service life of the anchor bolts.
5、Pipe Spacing Anchor BoltHigh Precision Drilling Required: The installation of tubular bolt anchors necessitates high-precision drilling; failure to meet the required precision may result in unstable anchor installation.
