Improving Soil Stability of Flood Control Culverts Under Amtrak Rails with Injection Grouts-Video

Video Transcription

Video Summary

In Meriden, Connecticut, restricted flow beneath an Amtrak bridge caused Harbor Brook to flood nearby homes and properties. Because the live tracks and bridge could not be raised, crews installed two steel casings through the embankment to house large HDPE diversion pipes. Low-viscosity AV-100 acrylamide grout was injected ahead of the advancing casings, stabilizing the granular soils while allowing excavation and construction to proceed safely. The installation succeeded and improved flood control. During questions, the presenter could not confirm the railroad’s monitoring requirements or the precise construction sequence, as he had not been on site.
