Self-drilling anchor system solutions for providing sufficient structural stability in bridge construction

Bridge construction often encounters unfavorable geological conditions such as loose, fractured or weak soils that can lead to borehole collapse and pose significant challenges to bar installation. The self-drilling anchor system eliminates the need for casing support, allowing direct drilling and grouting in these collapse-prone formations. This effectively solves borehole instability problems and ensures smooth construction progress.

Our Products Advantages

All products strictly comply with international ISO thread standards, including ISO 10208 and ISO 1720.The minimum Agt value for all SDA bar products is 5%, ensuring enhanced toughness and durability.
The self-drilling anchor system integrates drilling, grouting, and anchoring into a single process, eliminating the cumbersome steps of traditional methods. This significantly reduces construction time and allows for faster installation and anchoring during bridge construction, improving overall efficiency.
The self-drilling anchor system, equipped with a centralizer, ensures the anchor bar remains precisely centered within the borehole during drilling. This allows the grout to be evenly distributed around the bar, ensuring the required cement thickness is achieved and improving anchoring performance.
Grouting is performed simultaneously during drilling, allowing the grout to fully fill the borehole and any surrounding fissures. This ensures the anchor bar forms a tight bond with the surrounding soil and rock, creating a stable anchoring system that enhances both anchoring strength and pull-out resistance.
The anchoring system is compatible with small drilling rigs and suitable for use in confined spaces, making it adaptable to various bridge construction conditions.

Self-Drilling Anchor System

The self-drilling anchor system is an advanced anchoring solution on the market. It provides stability in soil or rock formations and is a key anchoring system in rock reinforcement projects, ensuring safety and structural rigidity.

Our self-drilling anchor is equipped with different parts. At the drilling end is the anchor bit, which creates the borehole while facilitating grouting. The anchor bolt, serves as the primary support structure. The anchor coupler extends the bolt's length when necessary, while the anchor plate distributes surface loads to ensure stability. Finally, the anchor nut locks the system securely in place, completing the setup for optimal performance.
