How to install gabion?

  •  Gabions must be installes on a surface prepared to the levels and quality of the levels and quality of the enginner's specifications for the project.
  • Rockfill for the gabions must be quarried rock of size and quality in accordance with the engineer's specifications for the project.
  • Beforce filling, gabions should be placed on the prepared surface and tensioned to ensure that the shape is good and that exposed surface are smooth and taut. A suitable tensioning arrangement is shown in Figure 8.

 

Fingure 8: Tensioned gabion ready for filling.

Note: For speed of construction several gabions may be laced together end-to-end with fully laced joints as on their adjoining vertical edges and tensioned as a unit.

  • Filling of gabions with rockfill may be by machine or hand tacking care to minimise voids. However , exposed face must be filled by hand using selected large pieces of rock with flat faces to give a fair face to the rockfill inside the expoaed geogrid face.
  • If the gabion height (H) is more than 500mm then cross-ties of HDPE braid should be installed as shown in Figure 9 at vertical intervals of 250-400mm to improve stabilty and quality of finish.
  • Slightly over-fill each gabion, using saller stones on the surface, to allow for settlement. Encourage settlement, for example by walking on the rockfill.
  • Adjust finished surface of rockfill as needed.
  • Equipment revetments
  • Close down top of gabion and tightly lace, all edges and top-diaphragm joints.
