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 a rare occurrence today. Roman pile bridges Pile bridges have been used to cross rivers and other geological chasms since at least the time of the Roman Empire. One such bridge was probably Pons Sublicius thought to have been first created around 642BC, although being made of wood; this bridge and none of the other Roman bridges of the period have survived the erosion of time. Construction during medieval times During the English Middle Ages bridge building was a booming activity. Groups of piles, usually ma ...

Starling (architecture)
In architecture, a starling (or sterling) is a defensive bulwark, usually built with pilings or bricks or blocks of stone, surrounding the supports (or piers) of a bridge or similar construction. Starlings may be shaped to ease the flow of the water around the bridge, reducing the damage caused by erosion or collisions with flood-borne debris or river traffic. They may also form an important part of the structure of the bridge, spreading the weight of the piers. The term ''cutwater'' is used for such a structure shaped with water flow in mind, as a pier or starling with a diamond point. A ''starkwater'' is a bulwark against ice floes. Depending on their shape and location, some starlings may accumulate river debris, mud and other objects, potentially creating navigational hazards or hindering downstream water flow. Shape Starlings may form part of a buttress for the vertical load of the bridge piers, so would typically be symmetrical. Other symmetrical starlings may be used ...

Fredriksdalsbron
Fredriksdalsbron is a bridge in central Stockholm, Sweden. Serving the light rail line Tvärbanan, it stretches north from the station west of the Gullmarsplan metro station, immediately makes a sharp eastward turn to plunge under two other bridges, Skanstullsbron and Johanneshovsbron, to continue eastward over a viaduct leading down to the station Mårtensdal in the newly built suburb Hammarby sjöstad. During the planning process the project name "Kvarnbron" (''Mill Bridge'') was used. The bridge was built by Nordic Construction Company (NCC) in 2000–2002 as the first part of an extension of the light rail. 379 metres in length, it rests on 15 pillars of which 2 are anchored into the bedrock while the others are steel point-bearing piles. The bridge deck is formed as a non-tensioned reinforced concrete tray rounded underneath.PDF) Abutments and revetments are dressed in slate. The maximum span is 30 metres, and the width varies from 9.4 to 11.4 metres. The longest pillar i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

London Bridge
The name "London Bridge" refers to several historic crossings that have spanned the River Thames between the City of London and Southwark in central London since Roman Britain, Roman times. The current crossing, which opened to traffic in 1973, is a box girder bridge built from concrete and steel. It replaced a 19th-century stone-arched bridge, which in turn superseded a 600-year-old stone-built medieval structure. In addition to the roadway, for much of its history, the broad medieval bridge supported an extensive built up area of homes and businesses, part of the City's Bridge (City of London ward), Bridge ward, and its southern end in Southwark was guarded by a large stone City gateway. The medieval bridge was preceded by a succession of timber bridges, the first of which was built by the Roman Empire, Roman founders of London (Londinium) around AD 50. The current bridge stands at the western end of the Pool of London and is positioned upstream from previous alignments. Th ...

Deck (bridge)
A deck is the surface of a bridge. A structural element of its superstructure, it may be constructed of concrete, steel Steel is an alloy of iron and carbon that demonstrates improved mechanical properties compared to the pure form of iron. Due to steel's high Young's modulus, elastic modulus, Yield (engineering), yield strength, Fracture, fracture strength a ..., grating, open grating, or wood. Sometimes the deck is covered by a track ballast, railroad bed and railroad track, track, asphalt concrete, or other form of pavement (material), pavement for ease of vehicle crossing. A concrete deck may be an integral part of the bridge structure (T-beam or double tee structure) or it may be supported with I-beams or steel girders. When a bridge deck is installed in a through truss, it is sometimes called a floor system. A suspended bridge deck will be suspended from the main structural elements on a suspension or arch bridge.

Pier
A pier is a raised structure that rises above a body of water and usually juts out from its shore, typically supported by piling, piles or column, pillars, and provides above-water access to offshore areas. Frequent pier uses include fishing, boat docking and access for both passengers and cargo, and oceanside recreation. Bridges, buildings, and walkways may all be supported by Pier (architecture), architectural piers. Their open structure allows tides and currents to flow relatively unhindered, whereas the more solid foundations of a quay or the closely spaced piles of a wharf can act as a Breakwater (structure), breakwater, and are consequently more liable to silting. Piers can range in size and complexity from a simple lightweight wooden structure to major structures extended over . In American English, a pier may be synonymous with a Dock (maritime), dock. Piers have been built for several purposes, and because these different purposes have distinct regional variances, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rubble
Rubble is broken stone, of irregular size, shape and texture; undressed especially as a filling-in. Rubble naturally found in the soil is known also as 'brash' (compare cornbrash)."Rubble" def. 2., "Brash n. 2. def. 1.

Building " Rubble-work" is a name applied to several types of masonry. One kind, where the stones are loosely thrown together in a wall between boards and grouted with mortar almost like concrete, is called in Italian "muraglia di getto" and in French "bocage". In Pakistan, walls made of rubble and concrete, cast in a formwork, are called 'situ', which probably derives from Sanskrit (similar to the Latin 'in situ' meaning 'made on the spot'). Work executed with more or less large stones put together without any attempt at courses is called rubble walling. Where similar work is laid in ...

Middle Ages
In the history of Europe, the Middle Ages or medieval period lasted approximately from the 5th to the late 15th centuries, similarly to the post-classical period of global history. It began with the fall of the Western Roman Empire and transitioned into the Renaissance and the Age of Discovery. The Middle Ages is the middle period of the three traditional divisions of Western history: classical antiquity, the medieval period, and the modern period. The medieval period is itself subdivided into the Early, High, and Late Middle Ages. Population decline, counterurbanisation, the collapse of centralised authority, invasions, and mass migrations of tribes, which had begun in late antiquity, continued into the Early Middle Ages. The large-scale movements of the Migration Period, including various Germanic peoples, formed new kingdoms in what remained of the Western Roman Empire. In the 7th century, North Africa and the Middle East—once part of the Byzantine Empire� ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foundation (architecture)
In engineering, a foundation is the element of a structure which connects it to the ground or more rarely, water (as with floating structures), transferring loads from the structure to the ground. Foundations are generally considered either shallow or deep. Foundation engineering is the application of soil mechanics and rock mechanics (geotechnical engineering) in the design of foundation elements of structures. Purpose Foundations provide the structure's stability from the ground: * To distribute the weight of the structure over a large area in order to avoid overloading the underlying soil (possibly causing unequal settlement). * To anchor the structure against natural forces including earthquakes, floods, droughts, frost heaves, tornadoes and wind. * To provide a level surface for construction. * To anchor the structure deeply into the ground, increasing its stability and preventing overloading. * To prevent lateral movements of the supported structure (in some cases ...
