Rapid Bridge Replacement
Rapid bridge replacement or accelerated bridge construction (ABC) is a technique that allows bridges to be replaced with minimum disruption to traffic. The replacement bridge is constructed on a site near the bridge to be replaced. When it is completed, the old bridge is cut away and removed using self-propelled modular transporters (SPMTs). Then the SPMTs lift the new bridge, transfer it to the work site and put it in place. Often the highway or railroad carried by the bridge is closed for just one weekend. Conventional techniques typically replace half a bridge at a time, with all highway traffic redirected under the other bridge half, often for a year or more, while construction progresses. Accelerated bridge construction (ABC) alternatives consist of ABC components and ABC techniques. Components can be categorized into prefabricated bridge elements (e.g. beams, bridge decks, footings, columns, pier caps, abutments etc.) or prefabricated bridge systems (e.g. bridge modules with ...

Thermal Lance
A thermal lance, thermic lance, oxygen lance, or burning bar is a tool that heats and melts steel in the presence of pressurized oxygen to create very high temperatures for cutting. It consists of a long steel tube packed with alloy steel rods, which serve as fuel; these are sometimes mixed with aluminum rods to increase the heat output. Operation One end of the tube is placed in a holder and oxygen is fed through the tube. The far end of the tube is pre-heated and lit by an oxyacetylene torch. An intense stream of burning steel is produced at the working end and can be used to cut rapidly through thick materials, including steel and concrete. The tube is consumed by the process within a few minutes. Applications Often used as a heavy duty demolition tool, the thermic lance is also used to remove seized axles of heavy machinery without damaging the bearings or axle housing. This technique is often used on the pins and axles of large equipment such as cranes, ships, bridges, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

It is tidal for over half of its length. It rises at York Pond in Eliot, and conjoined by brooks and creeks, feeds the tidal section. The York River flows southeast to the Atlantic Ocean at York Harbor in the town of York. The Abenaki name for the York River is ''Agamenticus'', which means "Beyond-the-hill-little-cove". According to Eben Norton Horsford, Agamenticus "described the site of the mouth of Little York River to one approaching it from the ''north'', as it lay behind the hill called by the Indians "Sassanows" (the modern Agamenticus). Little York River, a short tidal river, was the "Beyond-the-hill-little-cove."

Maine State Route 103
State Route 103 (SR 103) is a long state highway in extreme southern Maine. The route is signed east–west, but forms a half-loop, with most of its western segment running strongly southeast slightly inland of the Piscataqua River and the state border with New Hampshire, its central skirting the Piscataqua generally easterly, and its eastern strongly northeast slightly inland from the Atlantic Ocean. The route piggybacks on different roads with many turns throughout its length. Route description SR 103 begins in the west at an intersection with SR 236 (which is itself a former alignment of SR 103 there) west of Eliot, near its intersection with SR 101 just southwest of the border between South Berwick and Dover, New Hampshire. For its first mile SR 103 heads south-southwest, until crosses Sturgeon Creek, a tidal inlet of the Piscataqua River, the state border with New Hampshire. There it turns southeast to parallel the river, meandering slightly inland southeas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Double-tee
A double tee or double-T beam is a load-bearing structure that resembles two T-beams connected to each other side by side. The strong bond of the flange (horizontal section) and the two webs (vertical members, also known as stems) creates a structure that is capable of withstanding high loads while having a long span. The typical sizes of double tees are up to for flange width, up to for web depth, and up to or more for span length. Double tees are pre-manufactured from prestressed concrete which allows construction time to be shortened. History The developments of double tee were started in the 1950s by two independent initiatives, one by Leap Associates founded by Harry Edwards in Florida, and the other by Prestressed Concrete of Colorado. They designed the wings to expand the structural channel in order to cover more area at a lower cost. In 1951, Harry Edwards and Paul Zia designed a wide prestressed double tee section. Non-prestressed double tees were constructed in Miami ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
