Bridgewater Canal
The Bridgewater Canal connects Runcorn, Manchester and Leigh, Greater Manchester, Leigh, in North West England. It was commissioned by Francis Egerton, 3rd Duke of Bridgewater, to transport coal from his mines in Worsley to Manchester. It was opened in 1761 from Worsley to Manchester, and later extended from Manchester to Runcorn, and then from Worsley to Leigh. The canal is connected to the Manchester Ship Canal via a lock at Cornbrook; to the Rochdale Canal in Manchester; to the Trent and Mersey Canal at Preston Brook, southeast of Runcorn; and to the Leeds and Liverpool Canal at Leigh. It once connected with the River Mersey at Runcorn but has since been cut off by a slip road to the Silver Jubilee Bridge. Following the re-routing of roads to the Silver Jubilee Bridge, the Runcorn Locks Restoration Society campaigns to reinstate the flight of locks. The Bridgewater canal is described as the first great achievement of the canal age, although the Sankey Canal opened earlier. ...

John Gilbert (agent)
John Gilbert (1724–1795) was land agent and engineer to the Francis Egerton, 3rd Duke of Bridgewater, third Duke of Bridgewater and is credited with the idea that led to the building of the Bridgewater Canal. John Gilbert was born in Staffordshire. When he was aged 12–13 he was apprenticed to Matthew Boulton, a manufacturer of small metal objects and the father of Matthew Boulton, the engineer. When Gilbert was aged 19 his father died and he left his apprenticeship to superintend the family Lime (mineral), lime works. John's brother, Thomas, was working as agent to Granville Leveson-Gower, 1st Marquess of Stafford, Lord Gower, brother-in-law of the Duke of Bridgewater. Thomas invited John to inspect the Duke's coal mines at Worsley, and here John suggested the idea of a canal, to drain the mines and to convey the coal.Anon, p. 42. Around 1758 John was appointed as the Duke's agent and moved to live in Worsley. Here he started on the levelling and surveying work necessary for th ...

Navigable Aqueduct
Navigable aqueducts (sometimes called water bridges) are bridge structures that carry navigable waterway canals over other rivers, valleys, railways or roads. They are primarily distinguished by their size, carrying a larger cross-section of water than most water-supply aqueducts. Roman aqueducts were used to transport water and were created in Ancient Rome. The long steel Briare aqueduct carrying the Canal latéral à la Loire over the River Loire was built in 1896. It was ranked as the longest navigable aqueduct in the world for more than a century, until the Magdeburg Water Bridge in Germany took the title in the early 21st century. Early aqueducts such as the three on the Canal du Midi had stone or brick arches, the longest span being on the Cesse Aqueduct, built in 1690. But, the weight of the construction to support the trough with the clay or other lining to make it waterproof made these structures clumsy. In 1796 Longdon-on-Tern Aqueduct, the first large cast iron aqu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually related to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Worsley Four Foot Mine
The Manchester Coalfield is part of the South Lancashire Coalfield, the coal seams of which were laid down in the Carboniferous Period. Some easily accessible seams were worked on a small scale from the Middle Ages, and extensively from the beginning of the Industrial Revolution in the early 19th century until the last quarter of the 20th century. The Coal Measures lie above a bed of Millstone Grit and are interspersed with sandstones, mudstones, shales, and fireclays. The Lower Coal Measures occupy the high ground of the West Pennine Moors above Bolton and are not worked in the Manchester Coalfield. The most productive of the coal measures are the lower two thirds of the Middle Coal Measures where coal is mined from seams between the Worsley Four Foot and Arley mines. The deepest and most productive collieries were to the south of the coalfield. The coalfield is affected by the northwest to southeast aligned Pendleton Fault along the Irwell Valley and the Rossendale Valley anticl ...

Coal Measures
In lithostratigraphy, the coal measures are the coal-bearing part of the Upper Carboniferous System. In the United Kingdom, the Coal Measures Group consists of the Upper Coal Measures Formation, the Middle Coal Measures Formation and the Lower Coal Measures Formation. The group records the deposition of fluvio-deltaic sediments which consists mainly of clastic rocks (claystones, shales, siltstones, sandstones, conglomerates) interstratified with the beds of coal. In most places, the coal measures are underlain by coarser clastic sequences known as Millstone Grit, of Namurian age. The top of the coal measures may be marked by an unconformity, the overlying rocks being Permian or later in age. In some parts of Britain, however, the coal measures grade up into mainly coal-barren red beds of late Westphalian and possibly Stephanian age. Within the Pennine Basin these barren measures are now referred to as the Warwickshire Group, from the district where they achieve their thickest d ...

Geology
Geology () is a branch of natural science concerned with Earth and other astronomical objects, the features or rocks of which it is composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology, and so is treated as one major aspect of integrated Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure. It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks. By combining these tools, geologists are able to chronicle the geological history of the Earth as a whole, and also to demonstrate the age of the Earth. Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates. Geologists broadly study the properties and processes of E ...

Packhorse
A packhorse, pack horse, or sumpter refers to a horse, mule, donkey, or pony used to carry goods on its back, usually in sidebags or panniers. Typically packhorses are used to cross difficult terrain, where the absence of roads prevents the use of wheeled vehicles. Use of packhorses dates from the neolithic period to the present day. Today, westernized nations primarily use packhorses for recreational pursuits, but they are still an important part of everyday transportation of goods throughout much of the developing world and have some military uses in rugged regions. History Packhorses have been used since the earliest period of domestication of the horse. They were invaluable throughout antiquity, through the Middle Ages, and into modern times where roads are nonexistent or poorly maintained. Historic use in England Packhorses were heavily used to transport goods and minerals in England from medieval times until the construction of the first turnpike roads and canals in the ...

Mersey And Irwell Navigation
The Mersey and Irwell Navigation was a river navigation in North West England, which provided a navigable route from the Mersey estuary to Salford and Manchester, by improving the course of the River Irwell and the River Mersey. Eight locks were constructed between 1724 and 1734, and the rivers were improved by the construction of new cuts several times subsequently. Use of the navigation declined from the 1870s, and it was ultimately superseded by the Manchester Ship Canal, the construction of which destroyed most of the Irwell section of the navigation and the long cut between Latchford and Runcorn. History The idea that the Rivers Mersey and Irwell should be made navigable from the Mersey Estuary in the west to Manchester in the east was first proposed in 1660, and revived in 1712 by Thomas Steers. In 1720 the necessary bills were tabled. The Act of Parliament for the navigation was received in 1721. The construction work was undertaken by the Mersey & Irwell Navigation Co ...

Industrial Revolution
The Industrial Revolution was the transition to new manufacturing processes in Great Britain, continental Europe, and the United States, that occurred during the period from around 1760 to about 1820–1840. This transition included going from hand production methods to machines, new chemical manufacturing and iron production processes, the increasing use of steam power and water power, the development of machine tools and the rise of the mechanized factory system. Output greatly increased, and a result was an unprecedented rise in population and in the rate of population growth. Textiles were the dominant industry of the Industrial Revolution in terms of employment, value of output and capital invested. The textile industry was also the first to use modern production methods. The Industrial Revolution began in Great Britain, and many of the technological and architectural innovations were of British origin. By the mid-18th century, Britain was the world's leadi ...

Steam Engine
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed, by a connecting rod and crank, into rotational force for work. The term "steam engine" is generally applied only to reciprocating engines as just described, not to the steam turbine. Steam engines are external combustion engines, where the working fluid is separated from the combustion products. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. In general usage, the term ''steam engine'' can refer to either complete steam plants (including boilers etc.), such as railway steam locomotives and portable engines, or may refer to the piston or turbine machinery alone, as in the beam engine and stationary steam engine. Although steam-driven devices were known as early as the aeolipile in the f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cheshire Ring
The Cheshire Ring is a canal cruising circuit or canal ring, which includes sections of six canals in and around Cheshire and Greater Manchester in North West England: the Ashton Canal, Peak Forest Canal, Macclesfield Canal, Trent and Mersey Canal, Bridgewater Canal and Rochdale Canal. Because it takes boats approximately one week to complete the circuit, it is suited to narrowboat holidays that start at and return to the same location. The route has 92 locks and is long. It passes through contrasting landscapes between Manchester city centre and rural Cheshire with views of the Peak District and the Cheshire Plain. History The term "Cheshire Ring" first appeared in the Inland Waterways Association (IWA) Bulletin in 1965, where it was coined as part of a campaign to prevent the abandonment of, and restore navigation to, part of what had been known as the Peak Forest Circular Route between Manchester and Marple. When commercial carrying declined after the Second World War ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macclesfield Canal
The Macclesfield Canal is a canal in east Cheshire, England. There were various proposals for a canal to connect the town of Macclesfield to the national network from 1765 onwards, but it was not until 1824 that a scheme came to fruition. There were already suggestions by that date that a railway would be better, but the committee that had been formed elected for a canal, and the engineer Thomas Telford endorsed the decision. The canal as built was a typical Telford canal, constructed using cut and fill, with numerous cuttings and embankments to enable it to follow as straight a course as possible, although Telford had little to do with its construction, which was managed by William Crosley. The canal opened in 1831, and is long. All of its twelve locks are concentrated in a single flight at Bosley, which alters the level by . The canal runs from a junction with the Peak Forest Canal at Marple, Greater Manchester, Marple in the north, in a generally southerly direction, through ...
