ISTHA 4648 NSMJAWA Water Main Relocation
Des Plaines, IL
- 2 Drilled Shafts
- 2 Helical Anchors
This project consisted of relocating a 90” water main between Elmhurst Road and the Des Plaines Tollway Oasis and our work was to provide the drilled shafts to support the thrust restraint system for the new pipe. This system is composed of two 65” diameter caissons by 45-feet deep, with a W24x229 imbedded to the base of the shaft. At the top of these piles a W27x161 cross beam is welded connecting both caissons.
Additionally, we installed helical anchors for a soldier pile retaining wall. We also constructed two cantilevered sheet pile walls to limit the amount of contaminated soil removed from the site.
