Customize Your Desired Self Drilling Anchor Bolt

Anchor Bar Diameter and Length

The diameter and length of the self-drilling anchor bar are crucial, determined by the anticipated loads and the depth required for adequate anchorage. Larger diameters provide greater load-bearing capacity, while length depends on geotechnical analysis to ensure sufficient bond length within the stable ground formation.

Drill Bit Design

The sacrificial drill bit at the end of the anchor bar is customized based on the geological conditions. Different designs, such as carbide button bits for hard rock, clay bits for soft ground, or eccentric bits for overburden, optimize drilling efficiency and ensure proper penetration and hole formation in varying strata.

Corrosion Protection

For long-term performance and durability, especially in aggressive ground or corrosive environments, the self-drilling anchor bolts can be customized with various corrosion protection measures. Options include hot-dip galvanization, epoxy coatings, or stainless steel materials, extending the anchor’s lifespan and maintaining its structural integrity.

Grout Hole Configuration

The configuration of the grout holes within the hollow anchor bar can be customized to optimize grout injection and distribution. This includes varying the number, size, and pattern of the holes to ensure thorough permeation of the grout into the surrounding ground, enhancing the bond strength and load transfer capabilities of the anchor.

what is a Self Drilling Anchor Bolt?

A self-drilling anchor bolt is an innovative geotechnical anchoring system that combines the drilling and anchoring process into a single operation. Unlike traditional anchor bolts that require a pre-drilled hole, these hollow bars feature a sacrificial drill bit at one end, allowing them to bore into the ground while simultaneously serving as the anchor body. 

During drilling, grout can be injected through the hollow core, stabilizing the borehole and creating a strong bond with the surrounding soil or rock. This integrated approach offers significant advantages in terms of speed, efficiency, and stability, particularly in challenging ground conditions.

Self Drilling Anchor Bolt uses

Self-drilling anchor bolts are highly versatile and find extensive application across various construction and geotechnical engineering projects, particularly where ground conditions are challenging or efficiency is paramount.

  • Slope Stabilization: Crucial for reinforcing unstable slopes and embankments, preventing landslides and erosion on highways, railways, and in urban development.
  • Tunneling and Mining: Provide critical ground support for tunnel faces, roofs, and walls, enhancing safety and stability during excavation and long-term operation in underground environments.
  • Foundation Underpinning & Micropiles: Employed to strengthen existing foundations, underpin structures, or serve as new micropiles, offering reliable support in areas with weak or inconsistent ground.
  • Retaining Structures: Essential for anchoring retaining walls, sheet piling, and secant pile walls, providing lateral support for deep excavations and preventing soil movement.
  • Bridge and Dam Reinforcement: Used for anchoring bridge abutments, dam structures, and other heavy civil engineering components, especially in complex geological formations.
  • Temporary Support Systems: Frequently utilized for temporary ground support in various construction scenarios due to their rapid installation and effectiveness.

how to use Self Drilling Anchor Bolt

Using a self-drilling anchor bolt simplifies installation by combining drilling and grouting. This method provides efficient and reliable ground support for various construction and geotechnical applications.

Step 1: Prepare the Site and Equipment

Before commencing, ensure the work area is clear and safe. Position the drill rig accurately at the designated anchor location. Verify that all components, including the self-drilling anchor bolt, sacrificial drill bit, and grouting equipment, are in good working order and readily accessible.

Proper preparation ensures a smooth and efficient installation. Attach the appropriate drill bit to the anchor bolt. Confirm the grouting system is connected and primed, ready to deliver grout as drilling progresses, preventing delays in the process.

Step 2: Drill the Anchor Hole

Initiate drilling, allowing the self-drilling anchor bolt to penetrate the ground. The sacrificial drill bit efficiently cuts through soil or rock. Maintain consistent pressure and rotation to ensure the anchor advances steadily and accurately to the desired depth.

As drilling proceeds, continuously inject grout through the hollow core of the anchor bolt. This simultaneous grouting stabilizes the borehole, prevents collapse in unstable ground, and ensures proper bonding between the anchor and the surrounding geological formation.

Step 3: Grout the Anchor

Once the design depth is reached, continue pumping grout through the anchor bolt until the bore is completely filled and grout refusal is achieved. This ensures a strong, void-free bond with the surrounding ground, maximizing the anchor’s load-carrying capacity.

Allow the grout to cure fully according to specifications. The curing time is crucial for the grout to gain its intended strength, which is essential for the anchor’s long-term performance and the structural integrity of the supported element.
