Strelasund Crossing
Strelasund Crossing is the two links to the German island of Rügen (''Rugia'') over the Strelasund to the West Pomeranian mainland near Stralsund: the Rügen Bridge or Rugia Bridge () and the Rugia Causeway (). Ferry services between Stralsund and Altefähr and the Glewitz Ferry ("") between Stahlbrode and Zudar are also available to cross the Strelasund sound. The ''Rügendamm'' was the first fixed crossing over the sound of Strelasund, for both the old Bundesstraße 96, the Stralsund–Sassnitz railway and a combined footpath and cycle path. It was completed 1936/1937. ''Rügenbrücke'' is the name of the three-lane viaduct completed in 2007 exclusively for motor traffic, between the village of Altefähr on Rügen, Rugia Island and the Hanseatic town, Hanseatic and world heritage town of Stralsund; as part of the concept to turn the Bundesstraße 96, B96 and European route E22 into a ring road. Both bridges are operated in parallel. The Rugia Bridge has an overall length of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bundesstraße 96 Number
''Bundesstraße'' (, ), abbreviated ''B'', is the denotation for Germany, German and Austrian national highways. Germany Germany's ''Bundesstraßen'' network has a total length of about 40,000 km. German ''Bundesstraßen'' are labelled with rectangular yellow signs with black numerals, as opposed to the white-on-blue markers of the ''Autobahn'' controlled-access highways. ''Bundesstraßen'', like autobahns (''Autobahnen''), are maintained by the Federal agency (Germany), federal agency of the Federal Ministry of Transport, Building and Urban Development, Transport Ministry. In the German highway system they rank below autobahns, but above the ''Landesstraßen'' and ''Kreisstraßen'' maintained by the States of Germany, federal states and the Districts of Germany, districts respectively. The numbering was implemented by law in 1932 and has overall been retained up to today, except for those roads located in the former eastern territories of Germany. One distinguishing ch ...

Ring Road
A ring road (also known as circular road, beltline, beltway, circumferential (high)way, loop or orbital) is a road or a series of connected roads encircling a town, city or country. The most common purpose of a ring road is to assist in reducing traffic volumes in the urban centre, such as by offering an alternate route around the city for drivers who do not need to stop in the city core. Ring roads can also serve to connect suburbs to each other, allowing efficient travel between them. Nomenclature The name "ring road" is used for the majority of metropolitan circumferential routes in Europe, such as the Berliner Ring, the Brussels Ring, the Amsterdam Ring and the Leeds Inner and Outer ring roads. Australia, Pakistan, and India also use the term ring road, as in Melbourne's Western Ring Road, Lahore's Lahore Ring Road and Hyderabad's Outer Ring Road. In Canada the term is the most commonly used, with "orbital" also used, but to a much lesser extent. In Europe and Aust ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galvanized
Galvanization ( also spelled galvanisation) is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which the parts are coated by submerging them in a bath of hot, molten zinc. Protective action The zinc coating, when intact, prevents corrosive substances from reaching the underlying iron. It's main function is to act as a sacrificial anode to prevent the iron from rusting by cathodic protection. Zinc is more reactive than iron, so the zinc coating preferentially oxidizes to zinc carbonate, preventing the iron from corroding, even if there are gaps in the zinc coating. Additional electroplating such as a chromate conversion coating may be applied to provide further surface passivation to the substrate material. History and etymology The process is named after the Italian physician, physicist, biologist and philosopher Luigi Galvani (9 September 1737 – 4 December 1798). The earlies ...

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 and low raw material cost, steel is one of the most commonly manufactured materials in the world. Steel is used in structures (as concrete Rebar, reinforcing rods), in Bridge, bridges, infrastructure, Tool, tools, Ship, ships, Train, trains, Car, cars, Bicycle, bicycles, Machine, machines, Home appliance, electrical appliances, furniture, and Weapon, weapons. Iron is always the main element in steel, but other elements are used to produce various grades of steel demonstrating altered material, mechanical, and microstructural properties. Stainless steels, for example, typically contain 18% chromium and exhibit improved corrosion and Redox, oxidation resistance versus its carbon steel counterpart. Under atmospheric pressures, steels generally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Concrete
Concrete is a composite material composed of aggregate bound together with a fluid cement that cures to a solid over time. It is the second-most-used substance (after water), the most–widely used building material, and the most-manufactured material in the world. When aggregate is mixed with dry Portland cement and water, the mixture forms a fluid slurry that can be poured and molded into shape. The cement reacts with the water through a process called hydration, which hardens it after several hours to form a solid matrix that binds the materials together into a durable stone-like material with various uses. This time allows concrete to not only be cast in forms, but also to have a variety of tooled processes performed. The hydration process is exothermic, which means that ambient temperature plays a significant role in how long it takes concrete to set. Often, additives (such as pozzolans or superplasticizers) are included in the mixture to improve the physical prop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pylon (architecture)
A pylon is a monumental gate of an Egyptian temple (Egyptian: ''bxn.t'' in the Manuel de Codage transliterationErmann & Grapow, ''Wörterbuch der ägyptischen Sprache'', vol.1, 471.9–11). The word comes from the Greek term 'gate'. It consists of two pyramidal towers, each tapered and surmounted by a cornice, joined by a less elevated section enclosing the entrance between them.Toby Wilkinson, ''The Thames and Hudson Dictionary of Ancient Egypt'', Thames & Hudson, 2005. p.195 The gate was generally about half the height of the towers. Contemporary paintings of pylons show them with long poles flying banners. Egyptian architecture In ancient Egyptian religion, the pylon mirrored the hieroglyph ''akhet'' 'horizon', which was a depiction of two hills "between which the sun rose and set". Consequently, it played a critical role in the symbolic architecture of a building associated with the place of re-creation and rebirth. Pylons were often decorated with scenes emphasizing ...

Deep Foundation
A pile or piling is a vertical structural element of a deep foundation, driven or drilled deep into the ground at the building site. A deep foundation is a type of foundation (architecture), foundation that transfers building loads to the earth farther down from the surface than a shallow foundation does to a subsurface layer or a range of depths. There are many reasons that a geotechnical engineer would recommend a deep foundation over a shallow foundation, such as for a skyscraper. Some of the common reasons are very large design loads, a poor soil at shallow depth, or site constraints like property lines. There are different terms used to describe different types of deep foundations including the pile (which is analogous to a pole), the pier (which is analogous to a column), drilled shafts, and Caisson (engineering), caissons. Piles are generally driven into the ground ''in situ''; other deep foundations are typically put in place using excavation and drilling. The namin ...

Prestressed
Prestressed concrete is a form of concrete used in construction. It is substantially prestressed ( compressed) during production, in a manner that strengthens it against tensile forces which will exist when in service. Post-tensioned concreted is "structural concrete in which internal stresses have been introduced to reduce potential tensile stresses in the concrete resulting from loads." It was patented by Eugène Freyssinet in 1928. This compression is produced by the tensioning of high-strength ''tendons'' located within or adjacent to the concrete and is done to improve the performance of the concrete in service. Tendons may consist of single wires, multi-wire strands or threaded bars that are most commonly made from high-tensile steels, carbon fiber or aramid fiber. The essence of prestressed concrete is that once the initial compression has been applied, the resulting material has the characteristics of high-strength concrete when subject to any subsequent compression f ...

Abutment
An abutment is the substructure at the ends of a bridge span or dam supporting its superstructure. Single-span bridges have abutments at each end that provide vertical and lateral support for the span, as well as acting as retaining walls to resist lateral movement of the earthen fill of the bridge approach. Multi-span bridges require piers to support ends of spans unsupported by abutments. Dam abutments are generally the sides of a valley or gorge, but may be artificial in order to support arch dams such as Kurobe Dam in Japan. The civil engineering term may also refer to the structure supporting one side of an arch, or masonry used to resist the lateral forces of a vault.Pevsner, N. (1970) ''Cornwall''; 2nd ed. Harmondsworth: Penguin; p. 245 The impost or abacus An abacus ( abaci or abacuses), also called a counting frame, is a hand-operated calculating tool which was used from ancient times in the ancient Near East, Europe, China, and Russia, until the adoptio ...
