Precautions in Slope Control Construction: Ensuring Safety and Efficiency

Slope protection is a critical aspect of construction, especially in areas prone to landslides. Proper landslide management requires meticulous planning, adherence to construction methods, and stringent precautions. To ensure the safety and effectiveness of slope control construction, it is imperative to conduct a thorough geological investigation before commencing the project.

1. Accurate Geological Measurement: The Foundation of Success

In slope landslide management, accurate measurement of the slope's internal geology stands as the cornerstone for a safe and efficient project. To achieve this, the measurement process should undergo meticulous planning and execution. Here are the essential steps:

1.1 Multiple Measurements

The measurement process should not be a one-time affair. Multiple measurements are necessary to gather comprehensive data about the slope's geology. These measurements should be carried out at various points on the slope.

1.2 Protection of Measurement Points

Every measurement pile point should be treated with utmost care and precision. These points serve as the foundation for the entire project, so protecting them from potential damage during construction is crucial.

1.3 Protection of Critical Pile Points

Identify and prioritize critical pile points that are susceptible to damage during construction. Implement protective measures to ensure the integrity of these piles, thus guaranteeing the accuracy of the structures to be built.

2. Preconstruction Testing: Ensuring Material Quality

Before embarking on formal construction, rigorous testing of construction materials is paramount. The project's safety heavily relies on the quality of materials, including anchors, steel, cement, and more. Follow these guidelines:

2.1 Thorough Material Inspection

Conduct meticulous inspections of all construction materials, including anchors, steel, and cement. Ensure that these materials meet the highest standards of quality and safety, as they constitute the fundamental components of the project.


2.2 Steel Reinforcement Quality

Examine all steel reinforcement used in anti-slip piles to ensure smoothness and straightness. Prevent any entanglement or twisting of the reinforcement. Additionally, ensure the anchor rods' surfaces are clean, free of dirt, and devoid of rust issues.


3. Safe and Efficient Excavation: Focus on Pit Operations

Anti-slip pile pit excavation operations demand a heightened focus on safety. Poor stability of surrounding rock can pose significant challenges. To address this, consider the following precautions:

3.1 Depth Reduction in Unstable Rock

In areas where the stability of surrounding rock is questionable, prudently reduce the depth of each excavation cycle. This reduction mitigates the risk of collapses and ensures worker safety.

3.2 Timely Retaining Wall and Temporary Support

Implement retaining walls and necessary temporary support structures as needed. These safeguards should be executed meticulously to maintain the stability of the pit's rock walls. Adequate support is vital to prevent accidents during construction.

3.3 Temporary Slope Support

Recognize that during landslide management, slopes may have a propensity to collapse. Therefore, it is imperative to initiate temporary support measures on the slope before beginning the management process. These precautions are crucial for ensuring safety throughout construction.

The Preferred Construction Material for Slope Control

In slope support, there are two primary construction methods: ordinary rebar support and self-drilling hollow anchor bar support. While ordinary rebar support has its merits, self-drilling hollow anchor bars offer a more efficient alternative, especially in areas prone to collapse.

Self-Drilling Hollow Anchor Bars: A Game-Changer

Self-drilling hollow anchor bars combine drilling, grouting, and anchoring functions into a single streamlined process. Here's why they are the preferred choice:

1. Efficiency

Self-drilling hollow anchor bars expedite the construction process significantly. They eliminate the need for casing wall protection and allow for drilling, grouting, and anchoring to be completed in one go.

2. Grouting Flexibility

During drilling, grouting can be executed simultaneously, diluting slurry with a water/cement ratio of 1:1. Alternatively, drilling can precede grouting, with the hole cleared using water or air during drilling. After drilling to the required depth, grouting can be done, first with a dilute cement slurry and then with a thicker mixture (water-cement ratio of 0.45~0.6:1). This two-step grouting process ensures that the slurry fully fills rock fissures and tightly envelops the anchor rod, creating a robust anchor capable of withstanding slope deformation pressures.

3. Wide Applications

Self-drilling hollow anchor bars have found extensive use in slope protection, foundation reinforcement, and tunnel overrun support. Their versatility makes them a valuable asset in a variety of construction scenarios.

4. Cost-Effectiveness

The use of self-drilling hollow anchor bars not only improves construction efficiency but can also reduce overall project costs. Their multifunctionality and reliability contribute to cost savings while enhancing safety and performance.


Construction of slope control requires meticulous attention to detail and adherence to stringent precautions. Accurate geological measurements, thorough material testing, and safe excavation practices are vital to ensure project safety and efficiency. The use of self-drilling hollow anchor bars as a construction material offers numerous advantages, including improved efficiency and cost-effectiveness. By following these guidelines and embracing modern construction techniques, we can effectively protect slopes and mitigate landslide risks. It is essential to prioritize safety and high-quality workmanship throughout the entire project to achieve successful slope stabilization.
