Neptune's Staircase
Neptune's Staircase () is a staircase lock comprising eight locks on the Caledonian Canal. Built by Thomas Telford between 1803 and 1822, it is the longest staircase lock in Britain. The system was originally hand-powered but has been converted to hydraulic operation. Description Neptune’s Staircase at Banavie, near Fort William just north of Loch Linnhe, is kept by Scottish Canals. It is the longest staircase lock in Britain, lifting boats . It consists of eight locks, each by , and it takes boats about 90 minutes to pass through the system. The current lock gates weigh 22 tons each, and require a team of at least three lock-keepers to operate the staircase. They usually operate on an "efficiency basis"; that is, they try either to fill each cut with ascending boats or with descending boats, or to allow for passing, i.e. a dropping craft to pass a rising craft on the same fill/empty cycle. Prior to mechanisation, the locks were operated by capstans, each with four poles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caledonian Canal
The Caledonian Canal connects the Scottish east coast at Inverness with the west coast at Corpach near Fort William in Scotland. The canal was constructed in the early nineteenth century by Scottish engineer Thomas Telford. Route The canal runs some from northeast to southwest and reaches above sea level. Only one third of the entire length is man-made, the rest being formed by Loch Dochfour, Loch Ness, Loch Oich, and Loch Lochy. These lochs are located in the Great Glen, on a geological fault in the Earth's crust. There are 29 locks (including eight at Neptune's Staircase, Banavie), four aqueducts and 10 bridges in the course of the canal. Northern section The canal starts at its north-eastern end at Clachnaharry Sea Lock, built at the end of a man-made peninsula to ensure that boats could always reach the deep water of the Beauly Firth. Because the peninsula is built with mud foundations, it has required regular maintenance ever since. Next to the loc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swing Bridge
A swing bridge (or swing span bridge) is a movable bridge that has as its primary structural support a vertical locating pin and support ring, usually at or near to its center of gravity, about which the swing span (turning span) can then pivot horizontally as shown in the animated illustration to the right. Small swing bridges as found over canals may be pivoted only at one end, opening as would a gate, but require substantial underground structure to support the pivot. In its closed position, a swing bridge carrying a road or railway over a river or canal, for example, allows traffic to cross. When a water vessel needs to pass the bridge, road traffic is stopped (usually by traffic signals and barriers), and then motors rotate the bridge horizontally about its pivot point. The typical swing bridge will rotate approximately 90 degrees, or one-quarter turn; however, a bridge which intersects the navigation channel at an oblique angle may be built to rotate only 45 degrees, or ...

Fonserannes Locks
Fonseranes Locks (french: écluses de Fonseranes, ) are a flight of staircase locks on the Canal du Midi near Béziers. They consist of eight oval-shaped lock chambers, characteristic of the Canal du Midi, and nine gates, which allow boats to be raised a height of over a distance of . The flight was originally built as an eight-rise, which together with the ninth lock (the , to the northeast) allowed boats to cross the Orb river on a level and re-enter the canal further downstream. The "nine locks" name dates from this time. However, in 1858 an aqueduct was built to replace the crossing of the Orb. Boats now enter and leave the lower end of the flight through the side of chamber seven, which is permanently kept at its upper water level. The flight is therefore effectively made up of six locks. The lower gates of the seventh chamber are now permanently closed; the eighth chamber and the ninth lock, the pre-1858 route descending to the Orb, are disused. This side exit ...

History Of The British Canal System
History (derived ) is the systematic study and the documentation of the human activity. The time period of event before the invention of writing systems is considered prehistory. "History" is an umbrella term comprising past events as well as the memory, discovery, collection, organization, presentation, and interpretation of these events. Historians seek knowledge of the past using historical sources such as written documents, oral accounts, art and material artifacts, and ecological markers. History is not complete and still has debatable mysteries. History is also an academic discipline which uses narrative to describe, examine, question, and analyze past events, and investigate their patterns of cause and effect. Historians often debate which narrative best explains an event, as well as the significance of different causes and effects. Historians also debate the nature of history as an end in itself, as well as its usefulness to give perspective on the problems of the ...

Canals Of The United Kingdom
The canals of the United Kingdom are a major part of the network of inland waterways in the United Kingdom. They have a varied history, from use for irrigation and transport, through becoming the focus of the Industrial Revolution, to today's role of recreational boating. Despite a period of abandonment, today the canal system in the United Kingdom is again increasing in use, with abandoned and derelict canals being reopened, and the construction of some new routes. Canals in England and Wales are maintained by navigation authorities. The biggest navigation authorities are the Canal & River Trust and the Environment Agency, but other canals are managed by companies, local authorities or charitable trusts. The majority of canals in the United Kingdom can accommodate boats with a length of between and are now used primarily for leisure. There are a number of canals which are far larger than this, including New Junction Canal and the Gloucester and Sharpness Canal, which can ...

Grout
Grout is a dense fluid which hardens to fill gaps or used as reinforcement in existing structures. Grout is generally a mixture of water, cement and sand, and is employed in pressure grouting, embedding rebar in masonry walls, connecting sections of pre-cast concrete, filling voids, and sealing joints such as those between tiles. Common uses for grout in the household include filling in tiles of shower floors and kitchen tiles. It is often color tinted when it has to be kept visible and sometimes includes fine gravel when being used to fill large spaces (such as the cores of concrete blocks). Unlike other structural pastes such as plaster or joint compound, correctly mixed and applied grout forms a water resistant seal. Although both grout and its close relative mortar are applied as a thick emulsion and harden over time, grout is distinguished by its low viscosity and lack of lime (added to mortar for pliability); grout is thin so it flows readily into gaps, while mortar is ...

Drifter (fishing Boat)
A drifter is a type of fishing boat. They were designed to catch herring in a long drift net. Herring fishing using drifters has a long history in the Netherlands and in many British fishing ports, particularly in East Scottish ports. Until the mid-1960s fishing fleets in the North Sea comprised drifters and trawlers, with the drifters primarily targeting herring while the trawlers caught cod, plaice, skate and haddock, etc. By the mid-1960s the catches were greatly diminishing, particularly the herring. Consequently, the drifter fleet disappeared and many of the trawlers were adapted to work as service ships for the newly created North Sea oil rigs. Some history of drifters is covered in Scottish east coast fishery. Drifters preserved as museum ships include ''Lydia Eva'', a steam drifter of the herring fishing fleet based in Great Yarmouth, Norfolk, and ''Reaper'', a restored Scottish Fifie herring drifter at the Scottish Fisheries Museum.

First World War
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inverness
Inverness (; from the gd, Inbhir Nis , meaning "Mouth of the River Ness"; sco, Innerness) is a city in the Scottish Highlands. It is the administrative centre for The Highland Council and is regarded as the capital of the Highlands. Historically it served as the county town of the county of Inverness-shire. Inverness lies near two important battle sites: the 11th-century battle of Blàr nam Fèinne against Norway which took place on the Aird, and the 18th century Battle of Culloden which took place on Culloden Moor. It is the northernmost city in the United Kingdom and lies within the Great Glen (Gleann Mòr) at its northeastern extremity where the River Ness enters the Beauly Firth. At the latest, a settlement was established by the 6th century with the first royal charter being granted by Dabíd mac Maíl Choluim (King David I) in the 12th century. Inverness and Inverness-shire are closely linked to various influential clans, including Clan Mackintosh, Clan Fraser an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
