Crews drilled and installed permanent ground anchors for the new wall.


H-beams for the new soldier pile wall arrive at the project site. The beams are various sizes, measuring between 14-18 inches in width and up to 50 feet in length. 


Crews drill holes for the H-beams, which were placed vertically into the soil to form the structure of the soldier pile wall. The gaps in the beams were filled in with timber planks and gravel. 

The drill rig sits on a temporary work platform which is not part of the wall. To the left is the soil nail wall, which acts to temporarily stabilize the slope until the final wall is constructed.
 

Although these tubes look like mere plastic, they actually contain 3/4" thick high-tension steel cables encased in cement. The cables, or "nails," were attached to H-beams and run into the hillside, where they were anchored with concrete grout. When the grout cured, crews used a hydraulic jack to pull the cables taut and lock them in place. This will help to secure the wall and stabilize the hillside. 


Crews used a crane to lift the H-beams and place them in holes created by the drill rig.
