The Pont du Gard (c.19 BC), Nîmes; 3 rows of piers with arches springing from them to support the bridge. A pier, in architecture, is an upright support for a structure or superstructure such as an arch or bridge. Sections of structural walls between openings (bays) can function as piers.
A wave-dissipating concrete block is a naturally or manually interlocking concrete structure designed and employed to minimize the effects of wave action upon shores and shoreline structures, such as quays and jetties. One of the earliest designs is the Tetrapod, invented in 1950.
Beam bridges are the simplest structural forms for bridge spans supported by an abutment or pier at each end. [1] No moments are transferred throughout the support, hence their structural type is known as simply supported. The simplest beam bridge could be a log (see log bridge), a wood plank, or a stone slab (see clapper bridge) laid across a ...
Typical construction is either of a post and beam architecture, or a cantilever construction. The post-and-beam construction relies on posts anchored to piers in the ground. Typically, these types of structural decks are engineered and require an experienced construction company that specializes in structural decks.
Schematic cross section of a pressurized caisson. In geotechnical engineering, a caisson (/ ˈ k eɪ s ən,-s ɒ n /; borrowed from French caisson 'box', from Italian cassone 'large box', an augmentative of cassa) is a watertight retaining structure [1] used, for example, to work on the foundations of a bridge pier, for the construction of a concrete dam, [2] or for the repair of ships.
