Medway Viaducts
The Medway Viaducts are three bridges or viaducts that cross the River Medway between Cuxton and Borstal, Rochester, Borstal in north Kent, England. The two road bridges carry the M2 motorway (Great Britain), M2 motorway carriageways. The other viaduct carries the High Speed 1 railway line. All three bridges pass over the Medway Valley Line (to Paddock Wood railway station, Paddock Wood). The first Medway Viaduct, built to carry the M2 motorway, opened on 29 May 1963. It remained the only overcrossing of the river on this site until the 2000s, at which point two further bridges were constructed. The second Medway Viaduct was part of the M2 widening scheme, its opening in 2003 enabled the first bridge to be reconfigured to carry coast-bound road traffic only, while the new structure carried the London-bound traffic instead. Other remedial works to the older first bridge were also carried out around this time, including the replacement of its original concrete central span with a ...

Cuxton
Cuxton is a village in the unitary authority of Medway in South East England. It lies on the left bank of the River Medway in the North Downs. It is served by the A228, and Cuxton railway station on the Medway Valley Line between Strood and Maidstone. A low valley leads up from the river to the hamlet of Lower Bush. History Archaeological evidence suggest the first human occupation was around 200,000 years ago. A hoard of 196 handaxes from the Acheulian era was excavated in 1962. This is now displayed in the British Museum. The name is believed to have developed from "Cucula's stone".Judith Glover, The Place Names of Kent, 1976, Batsford. The remains of a Roman villa were found under the church yard. The Saxons occupied the town and it became known as Cuckelstane. The church and parish was given by Æthelwulf, King of the West Saxons to the Cathedral church of St. Andrew, Rochester. The church contains much Norman architecture, and is unusual as it lies on a southeast–n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ernest Marples
Alfred Ernest Marples, Baron Marples, (9 December 1907 – 6 July 1978) was a British Conservative politician who served as Postmaster General (1957–1959) and Minister of Transport (1959–1964). As Postmaster General, he oversaw the introduction of the Premium Bond scheme and of postcodes. His period as Minister of Transport was controversial. He both oversaw significant road construction (he opened the first section of the M1 motorway) and the closure of a considerable portion of the national railway network with the Beeching cuts. His involvement in the road construction business Marples Ridgway, of which he had been managing director, led to concerns regarding possible conflict of interest. In later life, Marples was elevated to the peerage before fleeing to Monaco at very short notice to avoid prosecution for tax fraud. Early life Marples was born at 45 Dorset Road, Levenshulme, Manchester, Lancashire. His father had been a renowned engineering charge-hand and Manches ...

Concrete Society
The Concrete Society is a UK based Nonprofit organization, non-profit company that was founded in 1966 in response to the increasing need for a single organisation embracing all those interested in concrete. On its formal inauguration, on 13 October 1966, the Society took over the work of the four organisations (the Reinforced Concrete Association, the Prestressed Concrete Development Group, the Pavings Development Group and the Formwork Development Group), by then in the process of dissolution, in order both to carry on their work and to extend it to cover the entire field of concrete technology and use. Today The Concrete Society is an Independent Concrete Advisory company. Over the years the company has become a provider of information serving the needs of clients, architects, engineers, specifiers, suppliers, contractors and users of concrete. The Society is an individual membership body, without trade affiliations, which exists to provide information to exchange information a ...

Articulation (architecture)
Articulation, in art and architecture, is a method of styling the joints in the formal elements of architectural design. Through degrees of articulation, each part is united with the whole work by means of a joint in such a way that the joined parts are put together in styles ranging from exceptionally distinct jointing to the opposite of high articulation—fluidity and continuity of joining. In highly articulated works, each part is defined precisely and stands out clearly. The articulation of a building reveals how the parts fit into the whole by emphasizing each part separately. Continuity and fusion The opposite of distinct articulation is continuity and fusion which reduces the separateness of the parts. Distinct articulation emphasizes the "strategic break" while the articulation of continuity concentrates on smooth transitions. Continuity (or fusion) reduces the independence of the elements and focuses on the largest element of the whole, while reducing focus ...

Deep Foundation
A deep foundation is a type of foundation that transfers building loads to the earth farther down from the surface than a shallow foundation does to a subsurface layer or a range of depths. A pile or piling is a vertical structural element of a deep foundation, driven or drilled deep into the ground at the building site. There are many reasons that a geotechnical engineer would recommend a deep foundation over a shallow foundation, such as for a skyscraper. Some of the common reasons are very large design loads, a poor soil at shallow depth, or site constraints like property lines. There are different terms used to describe different types of deep foundations including the pile (which is analogous to a pole), the pier (which is analogous to a column), drilled shafts, and caissons. Piles are generally driven into the ground in situ; other deep foundations are typically put in place using excavation and drilling. The naming conventions may vary between engineering discip ...

Channel Tunnel
The Channel Tunnel (french: Tunnel sous la Manche), also known as the Chunnel, is a railway tunnel that connects Folkestone (Kent, England, UK) with Coquelles ( Hauts-de-France, France) beneath the English Channel at the Strait of Dover. It is the only fixed link between the island of Great Britain and the European mainland. At its lowest point, it is deep below the sea bed and below sea level. At , it has the longest underwater section of any tunnel in the world, and is the third longest railway tunnel in the world. The speed limit for trains through the tunnel is . The tunnel is owned and operated by the company Getlink, formerly "Groupe Eurotunnel". The tunnel carries high-speed Eurostar passenger trains, the Eurotunnel Shuttle for road vehicles and international freight trains. It connects end-to-end with the high-speed railway lines of the LGV Nord in France and High Speed 1 in England. In 2017, through rail services carried 10.3 million passengers and 1.22 milli ...

High-speed Rail
High-speed rail (HSR) is a type of rail system that runs significantly faster than traditional rail, using an integrated system of specialised rolling stock and dedicated tracks. While there is no single standard that applies worldwide, lines built to handle speeds above or upgraded lines in excess of are widely considered to be high-speed. The first high-speed rail system, the Tōkaidō Shinkansen, began operations in Japan in 1964 and was widely known as the bullet train. High-speed trains mostly operate on standard gauge tracks of continuously welded rail on grade-separated rights of way with large radii. However, certain regions with wider legacy railways, including Russia and Uzbekistan, have sought to develop a high speed railway network in Russian gauge. There are no narrow gauge high-speed trains; the fastest is the Cape gauge Spirit of Queensland at . Many countries have developed, or are currently building, high-speed rail infrastructure to connect major citie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Downs Tunnel
The North Downs Tunnel, also known as the Blue Bell Hill Tunnel, is a railway tunnel that carries High Speed 1 through the North Downs, at Blue Bell Hill near Maidstone in Kent, south-east England. The tunnel is 3.2 kilometres (2 mi) long, with an internal diameter of 12 metres (40 ft) and a cross-sectional area (CSA) of 150 square metres, and descends to a depth of 100 m (325 ft) below the chalk hills. Thus, at the time of its completion, the North Downs Tunnel was both the largest (in terms of CSA) and deepest twin-track railway tunnels to have ever been constructed in the UK. Trains using High Speed 1 can reach 300 kilometres per hour (186 mph) whilst in the tunnel. Construction The North Downs Tunnel was constructed as one element of the first phase of the Channel Tunnel Rail Link (CTRL), which was subsequently rebranded as High Speed 1. Its north-west portal, the nearest to London, is positioned at the head of the Nashende ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crash Barrier
Traffic barriers (sometimes called Armco barriers,AK Steel (formerly Armco) genericized trademark also known in North America as guardrails or guard rails and in Britain as crash barriers) keep vehicles within their roadway and prevent them from colliding with dangerous obstacles such as boulders, sign supports, trees, bridge abutments, buildings, walls, and large storm drains, or from traversing steep (non-recoverable) slopes or entering deep water. They are also installed within medians of divided highways to prevent errant vehicles from entering the opposing carriageway of traffic and help to reduce head-on collisions. Some of these barriers, designed to be struck from either side, are called median barriers. Traffic barriers can also be used to protect vulnerable areas like school yards, pedestrian zones, and fuel tanks from errant vehicles. While barriers are normally designed to minimize injury to vehicle occupants, injuries do occur in collisions with traffic barriers. They ...
