Bridges Wallpapers - By construction of a Cofferdam. A cofferdam is a temporary structure designed to keep water and/or soil out of the excavation in which a bridge pier or other structure is built... The piles are constructed of wood, concrete or steel and are driven (i.e. hammered) into the ground until they are stable.

To use this method, builders dig a trench in the riverbed or ocean floor. They then sink pre-made steel or concrete tubes in the trench. After the tubes are covered with a thick layer of rock, workers connect the sections of tubes and pump out any remaining water.
