Rock Anchors With The Most Complete Specifications
Key Advantages of Rock Bolts
High Load-Bearing Capacity: By anchoring deep into rock formations, rock bolts effectively bear structural loads and counteract deformation forces, significantly enhancing overall rock stability.
Convenient Installation: The straightforward and efficient installation process substantially shortens project timelines while reducing labor and time costs.
Versatile Application: Suitable for diverse rock conditions and engineering scenarios, their specifications and materials can be flexibly customized to meet specific project requirements.
Advantages and Features of Rock Bolts with Product Analysis
As an efficient rock reinforcement solution, rock bolts play a pivotal role in tunnel, mine, and slope engineering projects. Boasting high load-bearing capacity, ease of installation, broad applicability, and cost-effectiveness, they have become the preferred choice for modern underground engineering support systems.
Swellex Rock Bolt Product Description
Swellex rock bolts are innovative products specifically designed for underground engineering support, widely used for rock reinforcement in tunnels, ramps, and mines. Their core utilizes expandable high-strength steel tubes that achieve exceptional anchoring performance by forming a comprehensive bond with the surrounding rock.
Core characteristics of Swellex Rock Bolts include:
Superior Expansion Performance: Expands via high-pressure water or grout injection to create friction-locking along the entire borehole length, significantly enhancing rock mass stability.
Rapid and Simple Installation: Requires no complex equipment, enabling swift support completion and markedly improving construction efficiency.
Exceptional Adaptability: Delivers reliable performance across diverse rock formations and complex geological conditions, accommodating varied support requirements.
High load-bearing capacity: Delivers outstanding tensile and shear resistance after expansion, effectively mitigating rockfall and landslide risks.
In summary, Swellex rock bolts provide robust safety assurance for underground projects like tunnels and mines through their reliability and high efficiency.
Mine Roof Bolts: Specifications and Characteristics of Slotted Bolts
Slotted bolts constitute a vital category among mine roof bolts, playing a critical role in mining roof support.
Specifications:
Outer Diameter (mm): φ30, φ33, φ40, φ43
Length (mm): 1200, 1500, 1800, 2000, 2500
Material: Q235, 16Mn, 20MnSi, and other high-strength alloy steels
Seam Tube Anchor Product Features:
High-Strength Structure: Constructed from high-strength alloy steel strip for robust support.
Triple-Action Support: When installed in slightly undersized boreholes, simultaneously applies radial pressure, frictional resistance, and tray bearing force to the surrounding rock.
Easy Installation: Streamlined operation enhances on-site work efficiency.
High Friction Resistance: Ensures immediate and effective ground pressure control.
Technical Requirements:
The surface shall be smooth without severe deformation or corrosion, and welds shall be intact without cracks.
The pull-out force of the lock ring weld ≥80 kN, ultimate tensile strength of the rod body ≥110 kN, initial anchoring force ≥25 kN/m, and tray load-bearing capacity ≥65 kN.
During installation, drill holes according to procedures, slide into the tray, and use an air hammer to install until the tray is flush with the roof. Select appropriate bolts and drill hole diameters based on rock conditions and relevant standards (e.g., GBJ86).
