Basic information:

Self-expandable ground anchors are immersed with the shock method and received a predominantly pulling load.

The anchor is used for:

  • fastening of masts, pipes, poles of a contact network of railways and other high-rise structures;
  • pipelines strengthening at the design elevations;
  • anchoring of caissons and tanks to prevent floating up;
  • fastening of foundation slabs;
  • fastening of sheet piling fences, retaining walls, walls of pits and trenches;
  • fastening of geogrids and other soil-restraining systems, including along the railway tracks;
  • fastening of the canvas in road and landscape works; when building in the water areas of rivers and seas;
  • land erosion control.

Advantages of self-expandable ground anchors:

  • High speed and easy installation of anchors, including on steep slopes;
  • Low cost of installation works due to lack of drilling and concreting costs.

Self-expandable ground anchor has a high load-bearing capacity. The use of this product allows significantly reduce the costs when creating and repairing of railway infrastructure facilities.
