Adam Viaduct
The Adam Viaduct is a grade II listed concrete underbridge in Wallgate, Wigan. The bridge, constructed in 1946, is the earliest prestressed concrete railway bridge in the United Kingdom, with only some examples in Switzerland being earlier. It is bridge number 54 on the Kirkby branch line and is at a line distance of . History and construction The bridge was constructed as a test case, to see if prestressed concrete construction was feasible for rail projects in the UK, by the LMS railway company, and designed by their chief civil engineer William Kelly Wallace. The beams used were prestressed using the Freyssinet system, in which concrete is precast with stressed high-tensile-strength metal tendons, which consist of multiple steel wires, running down the length of them. In construction, the beams internal rods are tightened and tied together so, under live load, they act as one. The LMS developed this system in the 1930s, and prestressed beams were first used for emergency ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wigan Today
The ''Wigan Post'' (formerly ''Wigan Evening Post and Chronicle'' and later just the ''Wigan Evening Post'') is a weekly (changed from daily in August 2021) tabloid British regional newspaper for Wigan in Greater Manchester (formerly in the traditional county of Lancashire). It is owned by Johnston Press and published by Lancashire Publications, which has its offices in the town. The main area for the paper's distribution is around the Metropolitan Borough of Wigan. It is published on Fridays. It was founded in the 1950s as a subdivision of the Lancashire Evening Post. The website which the Wigan Post shares with its sister papers is ''Wigan Today''. It also has an app for IOS and Android devices. Sister papers Wigan Observer The ''Wigan Observer'' is a weekly paid-for paper sold in the borough and is published each Tuesday. It was formed in 1853 as ''The Wigan Observer and District Advertiser'' and was family-run until 1966. Freesheets The ''Wigan Reporter'' was a freesheet we ...

Abutments
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 which 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 Civil engineering is a professional engineering discipline that deals with the design, construction, and maintenance of the physical and naturally built environment, including public works such as roads, bridges, canals, dams, airports, sewa ... 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.

Timber
Lumber is wood that has been processed into dimensional lumber, including Beam (structure), beams and plank (wood), planks or boards, a stage in the process of wood production. Lumber is mainly used for construction framing, as well as finishing (floors, wall panels, window frames). Lumber has many uses beyond home building. Lumber is sometimes referred to as timber as an archaic term and still in England, while in most parts of the world (especially the United States and Canada) the term timber refers specifically to unprocessed wood fiber, such as cut logs or standing trees that have yet to be cut. Lumber may be supplied either rough-sawmill, sawn, or surfaced on one or more of its faces. Beside pulpwood, ''rough lumber'' is the raw material for furniture-making, and manufacture of other items requiring cutting and shaping. It is available in many species, including hardwoods and softwoods, such as Pinus classification, white pine and red pine, because of their low cost. ...

Liverpool & Bury Railway
The Liverpool and Bury Railway was formed in 1845 and opened on 28 November 1848. The line ran from Liverpool Exchange first using a joint line with Liverpool, Ormskirk and Preston Railway before branching off to proceed via Kirkby then Wigan and Bolton to Bury. Mergers In 1846 the line merged with the Manchester & Leeds Railway being eventually finished after the merger to form the Lancashire and Yorkshire Railway (LYR). The portion of the line west of Crow Nest Junction eventually formed part of the LYR's Liverpool to Manchester route via a junction with the Manchester and Southport Railway at Wigan. From 1858 the line was connected to the Skelmersdale Branch and the St. Helens Railway at Rainford Junction. A short tunnel was bored through a hill between Upholland station and Orrell station. The line today With the exception of the section from Bolton to Bury (closed on 5 October 1970, along with the continuation through to ) the line is still in use, though Liverpool Excha ...

Victorian Era
In the history of the United Kingdom and the British Empire, the Victorian era was the period of Queen Victoria's reign, from 20 June 1837 until her death on 22 January 1901. The era followed the Georgian period and preceded the Edwardian period, and its later half overlaps with the first part of the ''Belle Époque'' era of Continental Europe. There was a strong religious drive for higher moral standards led by the nonconformist churches, such as the Methodists and the evangelical wing of the established Church of England. Ideologically, the Victorian era witnessed resistance to the rationalism that defined the Georgian period, and an increasing turn towards romanticism and even mysticism in religion, social values, and arts. This era saw a staggering amount of technological innovations that proved key to Britain's power and prosperity. Doctors started moving away from tradition and mysticism towards a science-based approach; medicine advanced thanks to the adopti ...

Parapet
A parapet is a barrier that is an extension of the wall at the edge of a roof, terrace, balcony, walkway or other structure. The word comes ultimately from the Italian ''parapetto'' (''parare'' 'to cover/defend' and ''petto'' 'chest/breast'). Where extending above a roof, a parapet may simply be the portion of an exterior wall that continues above the edge line of the roof surface, or may be a continuation of a vertical feature beneath the roof such as a fire wall or party wall. Parapets were originally used to defend buildings from military attack, but today they are primarily used as guard rails, to conceal rooftop equipment, reduce wind loads on the roof, and to prevent the spread of fires. In the Bible the Hebrews are obligated to build a parapet on the roof of their houses to prevent people falling (Deuteronomy 22:8). Parapet types Parapets may be plain, embattled, perforated or panelled, which are not mutually exclusive terms. *Plain parapets are upward extensio ...

I-beams
An I-beam, also known as H-beam (for universal column, UC), w-beam (for "wide flange"), universal beam (UB), rolled steel joist (RSJ), or double-T (especially in Polish, Bulgarian, Spanish, Italian and German), is a beam with an or -shaped cross-section. The horizontal elements of the are flanges, and the vertical element is the "web". I-beams are usually made of structural steel and are used in construction and civil engineering. The web resists shear forces, while the flanges resist most of the bending moment experienced by the beam. The Euler–Bernoulli beam equation shows that the I-shaped section is a very efficient form for carrying both bending and shear loads in the plane of the web. On the other hand, the cross-section has a reduced capacity in the transverse direction, and is also inefficient in carrying torsion, for which hollow structural sections are often preferred. History The method of producing an I-beam, as rolled from a single piece of wrought iro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

World War II
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 World War II by country, vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies of World War II, Allies and the Axis powers. World War II was a total war that directly involved more than 100 million Military personnel, 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. Air warfare of World War II, Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the Atomic bombings of Hiroshima and Nagasaki, only two nuclear weapons ever used in war.
