What is a segment bridge?
The
segment bridge is usually a concrete bridge that is assembled in small sections. Concrete can be occupied at a point where the bridge is built or premade elsewhere and brought. Upon completion, it seems that such a bridge usually has numerous divisions on it, where these sections are connected together. These are often associated with epoxy and steel support system. This may include deep valleys, wide waterways and a heavily traveled highway. Building a segment bridge, unlike a traditional bridge, can also reduce the amount of environmental disruption and daily commuting users.
To build a segment bridge, the building crew usually builds the support towers. These towers will hold the weight of the bridge itself and the transition. The crew generally builds these towers from the ground under the bridge and throws concrete to reach the underside of the actual overpass.
Once the towers are in place, the crew usually begins to work on the superstructureRun, which is a type of frame that sits on the top of each tower. This will hold the deck or span of the bridge. For bridges that are occupied on site, the building crew usually installs a steel frame and supportive before pouring the concrete for the span. For prefabricated bridges, workers can build a piece of steel frame in a piece when they attach each segment as a puzzle.
segmental bridges are a relatively new invention. The idea of this proposal was created in Europe. The first segment bridge in the world was built in Baluinstein, Germany in 1950, to cover the Lahn River. Was occupied on the spot. The first prefabrication bridge was built across the Seine River in France in 1962.
It took another decade for the segment bridge to come to the United States. The first built in the US was the Corpus Christi bridge in Texas. It was built in 1973 using prefabricated concrete beams. The first American bridge Cast onsite was built in San Diego in 1974.
other well -known segment bridges are the bridge of SevenPleasantly located on Florida Keys; Manwel Dimech Bridge in Malta; and the Four Bears bridge in northern Dakota. This type of bridge is still popular. Segmental design can be comfortable that can save time and money.
