REVISED OUTFALL CONSTRUCTION METHOD CONQUERS SURF AND SAND

When rugged surf and shifting sand halted construction of an ocean outfall sewer in Rio de Janeiro, a new contractor came in and completed the 2.6-mile job with revised techniques. Methods included powerful boom-mounted dredging pumps and a moveable jack-up barge for pile driving and concrete pipe placement. The major difficulty encourtered was dredging and keeping open the surf-zone trench for each 59-foot pipe section. It was found that the use of pipe piles instead of rock bed was a faster and cheaper construction method.
