Essential Requirements and Features of Ground Anchor Support

Ground anchor, to be brief, is a supporting method to fix engineering structures on a stable stratum. Ground anchor support is a vital method for ensuring the stability and safety of engineering structures built on stable strata. Among the various ground anchor systems available, the self-drilling anchor system stands out for its efficiency and effectiveness in providing reliable support.

I. Essential Requirements of Ground Anchor Support

1. Ensuring Earth Retaining Effect and Slope Stability

The primary purpose of ground anchor support is to maintain the stability of foundation pits and earth-retaining structures. This is achieved by embedding anchors deep into the ground, creating a reinforcing system that counteracts the lateral pressure exerted by soil and water. Self-drilling anchor systems excel in this regard, as they are made of high-strength steel, and the anchor bar of the system has a hollow core design and the threaded design along the length of the bar, and can quickly and efficiently penetrate various soil types, providing superior retention capabilities.

2. Ensuring Safety of Surrounding Structures and Utilities

One of the critical requirements of any ground anchor support system is to ensure the safety of nearby buildings, underground pipelines, and roads. During excavation and construction activities, the ground may experience deformation, settlement, collapse, or displacement. Self-drilling anchor systems, designed with high load-bearing capacity and excellent anchoring properties, help prevent such occurrences, reducing the risk of damage to surrounding structures and utilities.

3. Managing Groundwater in Water-Prone Regions

In regions with high groundwater levels, effective water management is essential to ensure successful construction. Ground anchors play a vital role in draining, redirecting, and intercepting groundwater during the construction process, allowing projects to be completed above the water table. Self-drilling anchor systems, equipped with grouting capabilities, effectively seal off water ingress points, further enhancing their suitability for water-prone areas.

II. Features of Ground Anchor Support

1. Harnessing the Soil's Bearing Capacity

Ground anchor support, particularly the self-drilling anchor system, intelligently utilizes the bearing capacity of the surrounding soil. By integrating the soil into the supporting structure, the anchors become an inherent part of the ground, offering enhanced stability and load-bearing capacity. This synergy ensures the efficient distribution of forces and reduces the chances of structural failure.

2. Lightweight Structure, Flexibility, and Earthquake Resistance

Self-drilling anchor systems boast a lightweight structure that does not add excessive load to the supported structure. This inherent flexibility allows them to adapt to ground movements, including those caused by seismic activities. As a result, these anchor systems significantly enhance the earthquake resistance and ductility of the supported structures, making them an ideal choice for seismically active regions.

3. Convenient, Safe, and Versatile Construction

The construction process of self-drilling anchor systems is straightforward and safe. The integrated drilling and anchoring mechanism reduce the number of required installation steps, making the process less labor-intensive and time-consuming. Moreover, the compact size of the drilling equipment allows for construction even in confined work yards, where space limitations would otherwise hinder traditional anchoring methods.

4. Unwavering Stability and Reliability

Upon completion of the anchoring process, self-drilling ground anchors exhibit remarkable stability and reliability. The tightly grouted bond between the anchor and the surrounding soil ensures minimal deformations and settlements. Furthermore, self-drilling anchor systems have impressive overload capacity, providing an additional safety margin for the supported structures.

5. Simultaneous Drilling and Support

One significant advantage of self-drilling anchor systems is their ability to facilitate simultaneous drilling and support. Traditional methods often require separate drilling and anchoring phases, which can be time-consuming. In contrast, the efficiency of self-drilling anchors allows construction teams to perform drilling and anchoring simultaneously, reducing the overall construction timeline significantly.


In conclusion, ground anchor support plays a crucial role in ensuring the stability and safety of various construction projects. Among the different types of ground anchor systems, the self-drilling anchor system excels in meeting the essential requirements of ground anchor support. Its ability to harness the soil's bearing capacity, lightweight structure, earthquake resistance, and versatility in construction make it a preferred choice for various underground projects. With the advancements in self-drilling anchor system technology, construction professionals can continue to rely on this innovative system for safe and efficient ground support in a wide range of geological conditions.
