Knocking-Undercut Anchor (KUA): An innovative method to improve the stability of engineering anchorage

Anchoring technology is widely used in various construction and engineering fields, such as tunnels, underground buildings, large structures and bridges. Traditional anchoring methods, including mechanical anchors, chemical anchors and grouting anchors, are effective but have certain limitations in some special environments. The Knocking-Undercut Anchor (KUA) method breaks through the limitations of traditional methods by combining knocking and undercut techniques, providing a more stable and reliable solution.

Working principle of Knocking-Undercut Anchor
KUA technology mainly relies on two basic principles:

Knocking: Through high-frequency knocking actions, tiny cracks and voids are generated inside the material, thereby achieving deep embedding of the anchoring system. This process not only increases the contact area of ​​the anchor point, but also enhances the connection strength through energy transfer.

Undercut: Undercut is achieved through the specific design of the anchor, which enables it to produce a certain undercut effect during installation. This effect enables the anchor to form a "hook-like" structure inside the material, enhancing its grip and fixing force. This design can effectively avoid the risk of falling off due to tension or shear force.

The combination of these two principles enables KUA anchors to provide excellent performance in many different environments, especially under high stress and complex geological conditions.

Application areas of KUA
Construction engineering: In construction engineering, KUA anchoring systems can be used for the foundation construction of large structures to ensure their stability under extreme conditions such as earthquakes and wind. It is especially suitable for construction projects such as basements, tunnels, and deep foundation pits.

Civil engineering: In civil engineering, KUA technology can be used to reinforce soil to prevent ground subsidence or landslides. In areas with poor soil stability, the use of KUA can greatly improve construction safety.

Bridges and transportation facilities: KUA technology can be used for pile foundation anchoring in bridge construction to ensure the long-term stability of bridges. In the construction of transportation facilities such as highways and railways, it can also effectively improve the wind and earthquake resistance of the structure.

Geotechnical Engineering: In geotechnical engineering, KUA technology is widely used for anchoring rock formations, especially in rock and unstable soils, and its performance is better than traditional anchoring technology.

Advantages and Challenges
Advantages:
Enhanced anchoring force: The fixing force of the anchor point is significantly improved by combining knocking and undercutting.
Adaptability: It can adapt to complex geological environments, especially in soft soil or loose materials.
Easy construction: The installation of the KUA system is relatively simple, without the need for complex equipment and technology, reducing construction costs and time.
