Laying pipes of a diameter 630mm and 100m whole length under the river. The steel pipe was as a cover for a pipe of a diameter 400mm with a protective coating. The strengthened foundation ditch in depth 6м, length 15м and width 4м. The engineering challenge of the given project was an abundance of subterranen waters. For the exhaustion of water out of excavation, we used drain pumps which had been mounted in one of the walls.
