Flying Arch
A flying arch is a form of arch bridge that does not carry any vertical load, but is provided solely to supply outward horizontal forces, to resist an inwards compression. They are used across cutting (transportation), cuttings, to avoid them collapsing inwards. Operation The conventional arch supports a vertical load downwards on the centre of the arch and translates this into forces both downwards and outwards at the base of the arch. In most cases, this sideways force is a nuisance and must be resisted by either strong foundations or a further 'bowstring' girder, in the form of a tied-arch bridge. In some cases though, originally for railway cuttings in loose rock, the sides of the cutting are unable to retain their own weight and tend to slide inwards. Flying arches may be provided to retain these side walls. Unlike the conventional arch, the vertical load on the arch does not carry a useful load, it is merely used to generate the side-thrust, which in this case is useful for ...

Llansamlet Flying Arches
Llansamlet is a suburban district and Community (Wales), community of Swansea, Wales, falling into the Llansamlet (electoral ward), Llansamlet ward. The area is centred on the A48 road (named Samlet Road and Clase Road in the area) and the M4 motorway. Like other places in Wales having a name beginning with Llan place name element, Llan, Llansamlet is named after a church, usually itself bearing the name of a saint – in this case, the church of Saint Samlet. There is a Saint Samlet's Church in the area on Church Road. History Historically, the region was part of the Deheubarth, Principality of Deheubarth until the Norman invasions between 1067 and 1101. From 1135 the Normans wrested the region from the Prince of Deheubarth and formed the basis for the Marcher Gower (Lordship), Lordship of Kilvey of comital rank. After the Laws in Wales Act 1535 abolished Marcher lordships, the region was incorporated into the county of Glamorgan. The parish of Llansamlet became part of the borou ...

South Wales Railway
The South Wales Railway ( cy, Rheilffordd De Cymru) was a main line railway which opened in stages from 1850, connecting the Great Western Railway from Gloucester to South Wales. It was constructed on the broad gauge. An original aspiration was to reach Fishguard to engender an Irish ferry transit and transatlantic trade, but the latter did not materialise for many years, and never became an important sector of the business. Neyland was the western terminus of the line until 1906. The company amalgamated with the Great Western Railway in 1863 and the track was converted to narrow (standard) gauge in 1873. In 1922–1923, most of the independent Welsh railways were constituents of the new enlarged Great Western Railway, enabling rationalisation and benefits of scale. Nearly all of the original main line of the South Wales Railway remains in use at present (2020). Proposals The prospectus of the South Wales Railway was issued in the summer of 1844. It proposed a railway with capital ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flying Buttress
The flying buttress (''arc-boutant'', arch buttress) is a specific form of buttress composed of an arch that extends from the upper portion of a wall to a pier of great mass, in order to convey lateral forces to the ground that are necessary to push a wall outwards. These forces arise from vaulted ceilings of stone and from wind-loading of roofs. The namesake and defining feature of a flying buttress is that it is not in contact with the wall at ground level, unlike a traditional buttress, and so transmits the lateral forces across the span of intervening space between the wall and the pier. To provide lateral support, flying-buttress systems are composed of two parts: (i) a massive pier, a vertical block of masonry situated away from the building wall, and (ii) an arch that bridges the span between the pier and the wall — either a segmental arch or a quadrant arch — the ''flyer'' of the flying buttress. History As a lateral-support system, the flying buttress was develope ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Correspondence & Travel Society

Cockett Tunnel
Cockett railway station was a former station on the West Wales Line from Swansea to Gowerton and onwards to . The station was located on the west side of Swansea in the residential area of Cockett. History The railway line between Landore and Carmarthen was opened on 11 October 1852 by the broad gauge South Wales Railway, which later became part of the Great Western Railway. The engineer of this line was Isambard Kingdom Brunel. Originally the first station westwards from Landore was at Loughor; Cockett and Gowerton stations were opened at later dates. Cockett station was closed to passenger traffic on and from 2 November 1964. There have been recent proposals to reopen the station as part of the Welsh Government's Rail infrastructure investment. Cockett Tunnel Just east of the station, towards Swansea, was the 829 yard Cockett Tunnel. The tunnel was cut through unstable soft ground and had wide cuttings at a shallow angle at either end. The tunnel suffered a partial co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grade II Listed
In the United Kingdom, a listed building or listed structure is one that has been placed on one of the four statutory lists maintained by Historic England in England, Historic Environment Scotland in Scotland, in Wales, and the Northern Ireland Environment Agency in Northern Ireland. The term has also been used in the Republic of Ireland, where buildings are protected under the Planning and Development Act 2000. The statutory term in Ireland is " protected structure". A listed building may not be demolished, extended, or altered without special permission from the local planning authority, which typically consults the relevant central government agency, particularly for significant alterations to the more notable listed buildings. In England and Wales, a national amenity society must be notified of any work to a listed building which involves any element of demolition. Exemption from secular listed building control is provided for some buildings in current use for worship, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isambard Kingdom Brunel
Isambard Kingdom Brunel (; 9 April 1806 – 15 September 1859) was a British civil engineer who is considered "one of the most ingenious and prolific figures in engineering history," "one of the 19th-century engineering giants," and "one of the greatest figures of the Industrial Revolution, hochanged the face of the English landscape with his groundbreaking designs and ingenious constructions." Brunel built dockyards, the Great Western Railway (GWR), a series of steamships including the first propeller-driven transatlantic steamship, and numerous important bridges and tunnels. His designs revolutionised public transport and modern engineering. Though Brunel's projects were not always successful, they often contained innovative solutions to long-standing engineering problems. During his career, Brunel achieved many engineering firsts, including assisting in the building of the first tunnel under a navigable river (the River Thames) and the development of the , the first ...

Arch Bridge
An arch bridge is a bridge with abutments at each end shaped as a curved arch. Arch bridges work by transferring the weight of the bridge and its loads partially into a horizontal thrust restrained by the abutments at either side. A viaduct (a long bridge) may be made from a series of arches, although other more economical structures are typically used today. History Possibly the oldest existing arch bridge is the Mycenaean Arkadiko Bridge in Greece from about 1300 BC. The stone corbel arch bridge is still used by the local populace. The well-preserved Hellenistic Eleutherna Bridge has a triangular corbel arch. The 4th century BC Rhodes Footbridge rests on an early voussoir arch. Although true arches were already known by the Etruscans and ancient Greeks, the Romans were – as with the vault and the dome – the first to fully realize the potential of arches for bridge construction.
