A.H. Beck installs drilled shaft foundation for a twin bridge on US-61 and other large drilled shafts for the railroad bridge on the Comite River near Denham Springs, Louisiana
The project is a portion of a larger 12 mile project to divert water from the Comite River to the Mississippi River. A H Beck installed 24 Р66ӯ drilled shaft foundation for twin bridge on US-61 and large 144ӯ Drilled Shafts for the railroad bridge. The railroad shafts were up to 200 ft deep and took approximately 700 cy of concrete per shaft. The shafts were drilled into sands and clays and the excavations were stabilized during drilling with bentonite slurry. A unique aspect of this project is that all of the shafts were installed from the existing level grade with the subsequent operation to excavate the canal, thus the top elevations of the drilled shafts were up to 44 ft below working grade at the time of construction.
