Yesterday I was watching documentary on a Bridge having piers founded in the water and was wondering how engineers and constructors are able to lay pile foundation in such a high-speed flowing water of river.
After research of few hours I have got a handful of knowledge about the technique we would be dealing with in this article.
eter. The segmental arcs are joined by special T-piles to the main cells. The circular-type cellular coffer dams are self-sustaining, and therefore independent of the adjacent circular cells. Each cell can be filled independently. The stability of such cells is much greater as compared with that of the diaphragm type. However, the circular cells are more expensive than the diaphragm type, as these require more sheet piles and greater skill in setting and driving the piles. Because the diameter of circular cells is limited by interlock tension, their ability to resist large lateral pressure due to high heads is limited.
