INNOVATION IN ANNULAR GROUTING AT THE EUCLID CREEK TUNNEL, CLEVELAND, OHIO

摘要

Void grouting behind concrete segmental tunnel linings is a relatively straightforward task in conjunction with an Earth Pressure Balance or Slurry Tunnel Boring Machine in soft ground. However, there are times when a segmentai lining is called for in a rock tunnel, with or without the need for such a TBM. This paper focuses on the Euclid Creek Tunnel in Cleveland, Ohio, and explains: what drove the selection of this lining system; the challenges that exist when using this system in a rock tunnel with an open TBM; and how the challenges were dealt with during construction
