Self Drilling Anchor Bolt - A Professional Solution for Marine Engineering and Slope Reinforcement
What is Self Drilling Anchor Bolt - A Professional Solution for Marine Engineering and Slope Reinforcement?
Self Drilling Anchor Bolt is an innovative anchoring system that integrates drilling and permanent support. Through an integrated design, it achieves a single step operation of "drilling installation grouting", greatly improving construction efficiency under complex geological conditions. This product is made of high-strength steel and is suitable for scenarios such as seawalls, dock revetments, and coastal road slopes that require high durability and stability. It can effectively resist risks such as seawater erosion, wave impact, and soil slip, and is a model of "fast, efficient, and reliable" support solutions in modern geotechnical engineering.
Product Overview
The Self-Drilling Anchor Bolt is an innovative anchoring system that integrates drilling and permanent support into one. Its unified design enables a "drill-install-grout" single-step operation, significantly improving construction efficiency in complex geological conditions. Manufactured by ChangQi using high-strength steel, this product is ideal for scenarios demanding exceptional durability and stability, such as seawalls, quay revetments, and coastal highway slopes. It effectively resists risks like seawater erosion, wave impact, and soil slippage, making it a model of "fast, efficient, and reliable" support solutions in modern geotechnical engineering.
Core Advantages: Breaking Tradition, Defining Efficiency
The core value of the Self-Drilling Anchor Bolt lies in simplifying construction processes and enhancing support effectiveness, as demonstrated by:
- One-step installation logic: No pre-drilling required—the anchor bolt comes with its own drill bit, enabling direct penetration through loose, fractured, or water-bearing strata. This eliminates the traditional four-step process of "drilling-hole cleaning-anchor installation-grouting," boosting construction efficiency by over 50%.
- Immediate stabilization capability: The anchor forms simultaneously during installation, eliminating the need for additional temporary supports. This significantly reduces construction risks, especially in high-risk scenarios like mines and tunnels.
- Exceptional compatibility: Supports both cement grout and pumped resin systems, allowing flexible selection based on project needs—cement grout is cost-effective and readily available, while resin offers rapid curing and high bonding strength, adapting to diverse geological conditions.
- High-pressure injection technology: Features high-pressure grouting capabilities to fully fill rock and soil fissures, ensuring tight integration between the anchor and surrounding medium, thereby significantly enhancing pull-out resistance and overall stability.
- Multi-spec customization: Adjustable outer diameter, length, and connection methods cater to diverse project requirements, from small slopes to large seawalls.
Technical Specifications Table: Precision in Every Detail

| Thread Type | Full-length continuous thread | Provides consistent pull-out resistance and torque transmission, avoiding localized failure |
| Standard Length | 1.5m, 2m, 3m, 6m, 12m | Example model R32-6.0: 32mm diameter, 6m length; non-standard lengths customizable |
| Corrosion Protection | Bare steel, hot-dip galvanized, epoxy-coated (optional) | Complies with ASTM A1055/A972 standards; hot-dip galvanizing ≥430g/㎡, suitable for high-corrosion marine environments |
| Connection Method | R/T-type threaded couplers, reduction sleeves, anchor plates | Facilitates multi-section anchor connections for long-distance anchoring (e.g., lengths over 12m) |
| Compatible Grout Systems | Cement grout, pumped resin | High compatibility; cement grout is cost-effective, resin cures rapidly (≤10 minutes) |
Applications: Where Stability is Needed, It Delivers
The versatility of Self-Drilling Anchor Bolts makes them the preferred choice for multi-domain geotechnical projects:
- Seawalls and quay revetments: Addresses seawater corrosion, wave impact, and soft soil settlement. High-pressure injection strengthens foundations, preventing revetment slippage. Hot-dip galvanizing or epoxy coatings resist seawater erosion, ensuring a service life of over 25 years.
- Coastal highway slopes: Rapid stabilization in weathered rock or loose sandy slopes prevents landslides and rockfalls caused by rain, ensuring road safety.
- Mining and tunneling: Ideal for fractured strata and fault zones, enabling anchoring without temporary supports for safer construction. Resin grout compatibility ensures rapid curing, shortening project timelines.
- Other scenarios: Also applicable to foundation pit support, bridge foundation reinforcement, and other stability-critical projects.
