Pile Bridge

A pile bridge is a structure that uses foundations consisting of long poles (referred to as piles), which are made of wood, concrete or steel and which are hammered into the soft soils beneath the bridge until the end of the pile reaches a hard layer of compacted soil or rock. Piles in such cases are hammered to a depth where the grip or friction of the pile and the soil surrounding it will support the load of the bridge deck. Bridging solely using the pile method is nowadays a rare occurrence.

Famous quotes containing the words pile and/or bridge:

    Wealth is an inborn attitude of mind, like poverty. The pauper who has made his pile may flaunt his spoils, but cannot wear them plausibly.
    Jean Cocteau (1889–1963)

    Crime seems to change character when it crosses a bridge or a tunnel. In the city, crime is taken as emblematic of class and race. In the suburbs, though, it’s intimate and psychological—resistant to generalization, a mystery of the individual soul.
    Barbara Ehrenreich (b. 1941)
