Old Rhine Bridge (Constance)
The Old Rhine Bridge at Konstanz spans the Seerhein. It is a combined road and railway bridge. In addition to one track of the High Rhine Railway at kilometer 413.5, it carries the , the road that connects the borough of Petershausen with the city centre. The road bridge carries two lanes into the city center and three lanes in the other direction. Additionally, there is a bicycle lane in both directions on the left (as seen from the city centre) and a sidewalk on the right. In the 19th century, distance markers were placed along the Rhine; they start counting kilometers at this bridge. History The first bridge over the Seerhein was built by the Romans at Gottlieben. Since the medieval trade routes to northern Italy, France and Eastern Europe crossed in Constance, it is assumed that a wooden bridge existed below Constance before the 10th century. The construction of a wooden pile bridge in the flight of around 1200 CE is documented. A mill was built into the bridge in 1 ...

Seerhein
The Seerhein ("Lake Rhine") is a river about four kilometres long, in the basin of Lake Constance. It is the outflow of the Upper Lake Constance and the main tributary of the Lower Lake Constance. The water level of the lower lake is about 30 cm below the level of the Upper Lake. It is considered part of the Rhine, which flows into Lake Constance as the Alpine Rhine and flows out of the Lake as the High Rhine. The Seerhein arose after the last ice age (the Würm glaciation, about 9650 BCE). Some time after this period, the water level of Lake Constance gradually dropped by about ten metres and the shallow parts fell dry. Some parts of the Seerhein still have a character a bit like a lake. The border between Germany and Switzerland runs down the center of the lower stretch of the river; the German city of Constance, the largest community on the river, is situated on both sides of the upper part. Location General The Seerhein extends over a length of 4.3 km ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pforzheim
Pforzheim () is a city of over 125,000 inhabitants in the federal state of Baden-Württemberg, in the southwest of Germany. It is known for its jewelry and watch-making industry, and as such has gained the nickname "Goldstadt" ("Golden City"). With an area of , it is situated between the cities of Stuttgart and Karlsruhe at the confluence of three rivers ( Enz, Nagold and Würm). It marks the frontier between Baden and Württemberg, being located on Baden territory. From 1535-65, it was the home to the Margraves of Baden-Pforzheim. The City of Pforzheim does not belong to any administrative district (''Kreis''), although it hosts the administrative offices of the Enz district that surrounds the town. During World War II, Pforzheim was bombed by the Allies a number of times. The largest raid, and one of the most devastating area bombardments of World War II, was carried out by the Royal Air Force (RAF) on the evening of 23 February 1945. Nearly one third of the town's po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Berthold II, Duke Of Carinthia
Berthold II, Duke of Carinthia (c. 1000 – 6 November 1078), also known as Berthold I of Zähringen, was a progenitor of the Swabian House of Zähringen. From 1061 until 1077, he was the Duke of Carinthia and Margrave of Verona. Life He was possibly a descendant of one Berthold (or Bezelin) von Villingen (d. 1024), a Swabian count in the Breisgau region and relative of the Ahalolfing dynasty. The early Zähringer were close allies of the Imperial Ottonian dynasty; Berthold von Villingen's son Count Birchtilo was among the nobles capturing and mutilating Antipope John XVI in 998, at the behest of Emperor Otto III. On his mother's side of the family, Berthold probably descended from the Hohenstaufen family, who then ruled as Swabian counts in Ortenau, Thurgau, Breisgau, and Baar. Berthold quickly rose to be one of the most powerful counts in Swabia, and the Salian emperor Henry III even promised his party-follower the title of Duke of Swabia, then held by Otto of Schweinfurt.

Gebhard Of Constance
Gebhard of Constance ( la, Gebhardus Constantiensis; german: Gebhard von Konstanz; 949 995 AD) was a bishop of Constance from 979 until 995. He founded the Benedictine abbey of Petershausen Petershausen is a municipality in the district of Dachau in Bavaria in Germany. Geography Petershausen is located in the valley of the Glonn with extensive floodplains. Much of the area outside of Petershausen is part of a nature preserve. His ... in 983.

Conrad Of Constance
Conrad of Constance (german: Konrad von Konstanz; la, Conradus, Curtius; 900 26 November 975) was a German bishop and saint. Life Conrad was a member of the powerful Welf family, son of Count Heinrich of Altdorf. After an education at the cathedral school in Constance, he became provost of Constance Cathedral and in 934 was made Bishop of Constance. It is counted as one of his achievements that he avoided becoming enmeshed in the politics of the day and reserved his energies for his episcopal duties. He was nevertheless close to Emperor Otto I, whom he accompanied to Italy in 962. Conrad made three pilgrimages to Jerusalem as well as a number to Rome. He founded a number of churches on the episcopal estates and the hospital at Kreuzlingen, named after a portion of the True Cross which Conrad brought back from Jerusalem and presented to it. Veneration His remembrance as a role model for courage was entirely due to the efforts of Bishop Ulrich I of Dillingen, Bishop of Consta ...

Deutsche Bundesbahn
The Deutsche Bundesbahn or DB (German Federal Railway) was formed as the state railway of the newly established Federal Republic of Germany (FRG) on 7 September 1949 as a successor of the Deutsche Reichsbahn-Gesellschaft (DRG). The DB remained the state railway of West Germany until after German reunification, when it was merged with the former East German Deutsche Reichsbahn (DR) to form Deutsche Bahn, which came into existence on 1 January 1994. Background After World War II, each of the military governments of the Allied Occupation Zones in Germany were ''de facto'' in charge of the German railways in their respective territories. On 10 October 1946, the railways in the British and American occupation zones formed the ''Deutsche Reichsbahn im Vereinigten Wirtschaftsgebiet'' (German Imperial Railway in the united economic area), while on 25 June 1947, the provinces under French occupation formed the Südwestdeutsche Eisenbahn. With the formation of the FRG these succe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Second World War
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rivet
A rivet is a permanent mechanical fastener. Before being installed, a rivet consists of a smooth cylindrical shaft with a head on one end. The end opposite to the head is called the ''tail''. On installation, the rivet is placed in a punched or drilled hole, and the tail is ''upset'', or ''bucked'' (i.e., deformed), so that it expands to about 1.5 times the original shaft diameter, holding the rivet in place. In other words, the pounding or pulling creates a new "head" on the tail end by smashing the "tail" material flatter, resulting in a rivet that is roughly a dumbbell shape. To distinguish between the two ends of the rivet, the original head is called the ''factory head'' and the deformed end is called the ''shop head'' or buck-tail. Because there is effectively a head on each end of an installed rivet, it can support tension loads. However, it is much more capable of supporting shear loads (loads perpendicular to the axis of the shaft). Fastenings used in traditional ...

Gantry Crane
A gantry crane is a crane built atop a gantry, which is a structure used to straddle an object or workspace. They can range from enormous "full" gantry cranes, capable of lifting some of the heaviest loads in the world, to small shop cranes, used for tasks such as lifting automobile engines out of vehicles. They are also called portal cranes, the "portal" being the empty space straddled by the gantry. The terms gantry crane and overhead crane (or bridge crane) are often used interchangeably, as both types of crane straddle their workload. The distinction most often drawn between the two is that with gantry cranes, the entire structure (including gantry) is usually wheeled (often on rails). By contrast, the supporting structure of an overhead crane is fixed in location, often in the form of the walls or ceiling of a building, to which is attached a movable hoist running overhead along a rail or beam (which may itself move). Further confusing the issue is that gantry cranes may ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sheet Pile
Retaining walls are relatively rigid walls used for supporting soil laterally so that it can be retained at different levels on the two sides. Retaining walls are structures designed to restrain soil to a slope that it would not naturally keep to (typically a steep, near-vertical or vertical slope). They are used to bound soils between two different elevations often in areas of terrain possessing undesirable slopes or in areas where the landscape needs to be shaped severely and engineered for more specific purposes like hillside farming or roadway overpasses. A retaining wall that retains soil on the backside and water on the frontside is called a seawall or a bulkhead. Definition A wall for holding in place a mass of earth or the like, as at the edge of a terrace or excavation. A retaining wall is a structure designed and constructed to resist the lateral pressure of soil, when there is a desired change in ground elevation that exceeds the angle of repose of the soil. A basement ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deutsche Reichsbahn
The ''Deutsche Reichsbahn'', also known as the German National Railway, the German State Railway, German Reich Railway, and the German Imperial Railway, was the German national railway system created after the end of World War I from the regional railways of the individual states of the German Empire. The ''Deutsche Reichsbahn'' has been described as "the largest enterprise in the capitalist world in the years between 1920 and 1932"; nevertheless its importance "arises primarily from the fact that the Reichsbahn was at the center of events in a period of great turmoil in German history". Overview The company was founded on 1 April 1920 as the ("German Imperial Railways") when the Weimar Republic, which still used the nation-state term of the previous monarchy, (German Reich, hence the usage of the in the name of the railway; the monarchical term was ), took national control of the German railways, which had previously been run by the German states. In 1924 it was reorganised ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
