摘要

This paper will discuss the unique history and techniques for restoring portions of the Chicago Sanitary and Ship Canal (CSSC) to acceptable safety standards.rnThe CSSC was constructed in the 1890's to reverse the natural flow of the Chicago River preventing Lake Michigan pollution. Today, it is used for sanitary, hydropower, flood control, and navigation. The CSSC is a perched canal for 2 miles north of the Lockport Lock. Both banks combine with the Lockport Lock and the Hydro-Powerhouse and Controlling Works to form an intricate water retaining complex that was classified as the riskiest, high-hazard navigation dam in 2004. The west side water retaining structure is a zoned earth embankment. On the east side, water is retained by a concrete wall backed by rock fill.rnThe 120-year-old system suffers from deterioration as evidenced in the canal walls by the visible deterioration, poor investigative cores, and numerous seepage areas. The opposite approach dike has experienced sloughing, sinkholes, and constant seepage. In 2004, a reliability assessment identified stability and pool loss concerns.rnRepair concepts required minimal impacts to canal operations. In 2007, contractors constructed a 4,300 foot slurry trench cut-off wall using hydromill technology in the earth embankment. Construction is underway for repair of the concrete canal wall under full pool. New precast concrete panels will be placed in a rock trench in the channel floor and tied back to an anchor wall. Infill concrete will then be placed, encapsulating the old wall.
