SUBWAY FIGHTS POOR SOIL IN SEVEN DIFFERENT WAYS

The paper reports that German contractors are using seven different methods to build a 2-mile stretch of subway through poor soil in a congested area of West Berlin. Most of the project is being carried out without dewatering and resembles a marine construction job more than dry-land tunneling. Approaching a river crossing, the job shifts to giant concrete caissons built on grade and sunk through the soil. The job is divided by diaphragm walls of double steel sheetpiles placed every 350 ft. They help resist soil pressure and allow dewatering and finished tunnel construction to take place in stages.
