In mid-2019, EEI designed a temporary support of excavation wall for the Trout Run Dam Spillway Improvement Project in Earl Township, Pennsylvania. The wall was designed using soil nails and shotcrete fascia.
EEI also performed a variety of tests on baffle block anchors and weir tie-downs. One of the unique challenges encountered was how to suspend the testing apparatus over a wide and deep pit where the weir would later be installed. This was accomplished using crane pads stacked on both sides of the pit, over which a “bridge” was constructed to mount the hydraulic jack using an iron H beam.
