Know about ground anchors before installing them


7 4 月, 2024



Anchoring is highly important for installing a retaining system. So, you need to use ground anchors for your geotechnical projects. Using a ground anchor rod, you can secure diaphragm walls, sheet piles, and pile walls. Installing this anchor is a cost-effective and functionally efficient option. Let us talk more about ground anchors.

Why should you use ground anchors?

A ground anchor rod provides several advantages.

  • If ground conditions are not favorable, the anchor rod is effective for holding high loads.
  • It is made from corrosion-resistant material ensuring high durability.
  • The ground anchor can sustain the earth’s retention.
  • You can use it for various soil conditions.
  • It is also intended for permanent use in ports and roads.
  • The anchor rod does not cause significant environmental effects.

What are various types of ground anchors?

Before making an investment, you need to learn about diverse types of ground anchors.

Some ground anchors are intended to be used in the stable rock strata. They are also known as rock anchors. If there are collapsible soils, you need to use a rotary percussive rig.

There are ground anchors used in cohesionless and cohesive soils. Use a rotary percussive rig or rotary to make an anchor hole.

Another type of ground anchor is perfect for clay strata. It has a load-bearing capacity depending on the clay strength. The best anchor unit includes a cylindrical shaft drilling. 

Some anchors are temporary, as they are removed. But most ground anchors are permanent and last for more than 2 years. You can implement them as strand anchors or single-rod tube anchors. The anchor head has a hollow space filled with corrosion-proof substances.

Test the ground anchors before installing them

Load testing is essential before you install the ground anchor rod. It will help you determine load distortion and load capacity before installation.

Performance analysis- Load and unload the production anchor for this test. Prove the load deformation and load capacity of your anchor. Identify the factors causing anchor movements and confirm that the unbounded length matches the anchor design.

Proof test- It is another test involving a load hold and a single load cycle. The applied load degree is measurable with a pressure gauge.

What are the various applications?

In the construction industry, the ground anchor rod is used for stabilizing

  • Excavation trenches
  • Slopes
  • Retaining walls

You can use the anchor rod for anchoring

  • Towers
  • Bridges
  • Buildings

Another application for ground anchors is for installing

  • Guy wires
  • Poles
  • Landslide mitigation projects

Factors that affect ground anchor’s performance

You have to focus on various factors before installing the ground anchor.

  • Not every type of soil has the same load-bearing ability. So, the soil type will affect the ground anchor potential.
  • Proper installation techniques are vital to ensure the performance and stability of the anchor rod.
  • Temperature fluctuations and other environmental factors may affect the durability of the ground anchor.

So, buy the ground anchor rod for different projects and meet your needs.
