Summary
[edit]DescriptionLevee drill work near Capital City Freeway (15699611228).jpg |
Crews for the U.S. Army Corps of Engineers Sacramento District continue levee seepage cutoff wall work Nov. 24, 2014, where the Capital City Freeway meets the American River in Sacramento, California. Contractors use jet grouting, a surgically-precise method of vertically drilling into the levee and injecting special cement mixtures in overlapping columns, to strengthen the levee when construction is constrained by encroachments like buried utilities, power lines and bridges. The Sacramento District built more than 20 miles of seepage cutoff walls into American River levees between 2000 and 2002, but set aside work around complicated encroachments until now.
