The Application of Self Drilling Anchor Bolt in Beijing Oriental Plaza Foundation Support Project

In the realm of modern construction and engineering, the utilization of cutting-edge technologies and innovative methodologies is paramount to overcoming the challenges posed by complex geological conditions and formidable project scopes. A prime testament to this is the remarkable application of a self-drilling anchor system in the monumental Beijing Oriental Plaza Foundation Support Project. As the landscape of construction evolves, these self-drilling anchor bolts are emerging as invaluable tools, revolutionizing the very essence of foundation support projects.

Overview of Self-Drilling Anchor Bolt

In recent years, the self-drilling anchor bolt has risen to the forefront of foundation support endeavors, eclipsing traditional methods due to its expedient installation process and efficacy within unconsolidated ground conditions. Beyond their utility, these self-drilling anchor bolts embody an array of commendable features, each enhancing their appeal and elevating them to indispensable status:

Dual-Performance Excellence

One of the most remarkable attributes of the self-drilling anchor bolt is its dual-performance nature, encompassing both drilling and grouting capabilities. A distinctive hollow bore design serves a dual purpose: facilitating efficient flushing during drilling and enabling simultaneous grouting operations. This twin-functionality not only expedites the installation process but also enhances the overall stability of the support structure.

Versatile Sizing Options

The self-drilling anchor bolt, available in a range of sizes, boasts borehole dimensions spanning 40mm to 300mm. The selection of the optimal anchor bolt size is contingent upon the specific requirements of the project, rendering it a versatile solution adaptable to diverse scenarios.

Threaded Connectivity

The ease of connecting anchor bars with full threading contributes to the unparalleled adaptability of self-drilling anchor bolts. This threaded connectivity feature empowers engineers and construction teams to seamlessly adjust the length of anchor bolts as necessitated by the project, fostering a tailored and precise approach.

Resilience in Challenging Environments

A hallmark of the self-drilling bolt anchor is its compatibility with fractured geological conditions and confined spaces. In the crucible of broken geological formations and restricted workspaces, these anchor bolts have repeatedly demonstrated their mettle by delivering impeccable results, thus fortifying their credibility and reliability.

The Beijing Oriental Plaza Foundation Support Project

The resounding success and efficacy of self-drilling anchor bolts find embodiment in the iconic Beijing Oriental Plaza Foundation Support Project. Noteworthy not only for its sheer magnitude but also for its intricate geological challenges, this project represents an archetype of modern construction engineering overcoming adversity.


The Beijing Oriental Plaza Foundation Support Project presented significant challenges due to its extensive scope and complex geological conditions. The project involved a substantial volume of work, including the dismantling of numerous barrier buildings. These factors, combined with the geological complexities, posed considerable construction difficulties. To overcome these challenges, the project employed a combination of cast-in-situ bored piles, socketed H-shaped piles, pre-stressed anchor cables, and soil nailing, with the self-drilling anchor bolt system playing a pivotal role in the overall support structure.

Supporting Structure Design

The supporting structure of the Beijing Oriental Plaza Foundation Support Project incorporated 800mm* 1000mm, 1.5m-distance cast-in-situ bored piles and socketed H-shaped piles. To reinforce the foundation, the self-drilling anchor bolt system was employed in conjunction with pre-stressed anchor cables and soil nailing. This compound-supporting structure ensured the stability and integrity of the foundation.

Retaining Wall Construction

To enhance the overall stability of the foundation, a retaining wall was constructed. The wall was bricked below the ground at a depth of 1.5~2.5m, providing additional support to the structure. At the top of the pile, a top hat beam was constructed to further strengthen the retaining wall. This combination of measures ensured the structural integrity of the foundation and the stability of the entire supporting system.

Monitoring and Results

Following the completion of the Beijing Oriental Plaza Foundation Support Project, a comprehensive monitoring system was put in place to assess the stability of the supporting structure. Over the course of one year, the monitoring results consistently met the designed requirements, confirming the effectiveness of the self-drilling anchor system and its contribution to the overall success of the project. The stability achieved throughout the monitoring period provided reassurance that the foundation would withstand the test of time.


The Beijing Oriental Plaza Foundation Support Project serves as a compelling case study for the application of a self-drilling anchor system in complex construction scenarios. The project's challenges, including a large volume of work, complicated geological conditions, and the need to dismantle barrier buildings, were effectively addressed through the implementation of the self-drilling anchor system. The project's successful outcome, as evidenced by the one-year monitoring results, further solidifies the self-drilling anchor bolt's position as a reliable and efficient solution for foundation support projects.
As the demand for foundation support projects continues to grow, self-drilling anchor bolts are poised to play an even more prominent role in ensuring the safe and efficient construction of structures worldwide.
