Lock (water Transport)
A lock is a device used for raising and lowering boats, ships and other watercraft between stretches of water of different levels on river and canal waterways. The distinguishing feature of a lock is a fixed chamber in which the water level can be varied; whereas in a caisson lock, a boat lift, or on a canal inclined plane, it is the chamber itself (usually then called a caisson) that rises and falls. Locks are used to make a river more easily navigable, or to allow a canal to cross land that is not level. Later canals used more and larger locks to allow a more direct route to be taken. Pound lock A ''pound lock'' is most commonly used on canals and rivers today. A pound lock has a chamber with gates at both ends that control the level of water in the pound. In contrast, an earlier design with a single gate was known as a flash lock. Pound locks were first used in China during the Song Dynasty (960–1279 AD), having been pioneered by the Song politician and naval en ...

Thomas Telford
Thomas Telford FRS, FRSE, (9 August 1757 – 2 September 1834) was a Scottish civil engineer. After establishing himself as an engineer of road and canal projects in Shropshire, he designed numerous infrastructure projects in his native Scotland, as well as harbours and tunnels. Such was his reputation as a prolific designer of highways and related bridges, he was dubbed ''The Colossus of Roads'' (a pun on the Colossus of Rhodes), and, reflecting his command of all types of civil engineering in the early 19th century, he was elected as the first President of the Institution of Civil Engineers, a post he held for 14 years until his death. The town of Telford in Shropshire was named after him. Early career Telford was born on 9 August 1757, at Glendinning, a hill farm east of Eskdalemuir Kirk, in the rural parish of Westerkirk, in Eskdale, Dumfriesshire. His father John Telford, a shepherd, died soon after Thomas was born. Thomas was raised in poverty by his mother Janet Jac ...

Caisson Lock
The caisson lock is a type of canal lock in which a narrowboat is floated into a sealed watertight box and raised or lowered between two different canal water levels. It was invented in the late 18th century as a solution to the problem posed by the excessive demand for water when conventional locks were used to raise and lower canal boats through large height differences. Such locks, each of which would only raise and lower boats through small height differences of a few feet, would not suffice when large height differences had to be tackled nor when water was in short supply. The caisson (or ) was thought to be one solution, although it transpired that the technology of the day was not capable of achieving this type of construction economically. It was designed primarily as a water-saving measure, and also was an attempt to minimise construction costs compared with other engineering solutions of the time. In use it was capable of replacing up to seven conventional locks. Othe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caisson (engineering)
In geotechnical engineering, a caisson ( or ; borrowed from French ''caisson'', from Italian ''cassone'', meaning ''large box'', an augmentative of ''cassa'') is a watertight retaining structure used, for example, to work on the foundations of a bridge pier, for the construction of a concrete dam, or for the repair of ships. Caissons are constructed in such a way that the water can be pumped out, keeping the work environment dry. When piers are being built using an open caisson, and it is not practical to reach suitable soil, friction pilings may be driven to form a suitable sub-foundation. These piles are connected by a foundation pad upon which the column pier is erected. Caisson engineering has been used at least since the 18th century, and was notably used in the construction of the Brooklyn Bridge, which was completed in 1883. Types To install a caisson in place, it is brought down through soft mud until a suitable foundation material is encountered. While bedrock is pref ...

Boat Lift
A boat lift, ship lift, or lift lock is a machine for transporting boats between water at two different elevations, and is an alternative to the canal lock. It may be vertically moving, like the Anderton boat lift in England, rotational, like the Falkirk Wheel in Scotland, or operate on an inclined plane, like the Ronquières inclined plane in Belgium. History A precursor to the canal boat lift, able to move full-sized canal boats, was the tub boat lift used in mining, able to raise and lower the 2.5 ton tub boats then in use. An experimental system was in use on the Churprinz mining canal in Halsbrücke near Dresden. It lifted boats using a moveable hoist rather than caissons. The lift operated between 1789 and 1868,Charles Hadfield ''World Canals: Inland Navigation Past and Present'', p. 71, and for a period of time after its opening engineer James Green reporting that five had been built between 1796 and 1830. He credited the invention to Dr James Anderson of Edinburgh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Locks On The Kennet And Avon Canal
The Kennet and Avon Canal is a canal in southern England. The name may refer to either the route of the original Kennet and Avon Canal Company, which linked the River Kennet at Newbury to the River Avon at Bath, or to the entire navigation between the River Thames at Reading and the Floating Harbour at Bristol, including the earlier improved river navigations of the River Kennet between Reading and Newbury and the River Avon between Bath and Bristol. The River Kennet was made navigable to Newbury in 1723, and the River Avon to Bath in 1727. The Kennet and Avon Canal between Newbury and Bath was built between 1794 and 1810 by John Rennie, to convey commercial barges carrying a variety of cargoes, and is 57 miles (92 km) long. The two river navigations and the canal total 87 miles (140 km) in length. The section from Bristol to Bath is the course of the River Avon, which flows through a wide valley and has been made navigable by a series of locks and weirs. I ...

Limehouse Basin Lock
Limehouse Basin Lock is a lock forming the exit from Limehouse Basin to the Thames, in the London Borough of Tower Hamlets, England. It is the final lock on the Regent's Canal. The Narrow Street swing bridge sits between the lock and the river. The current lock was built in 1989 for yachts and pleasure craft, to conserve water in the Basin. It measures by and was built completely within the chamber of the former Ship Lock entrance to the basin. This measured by . The original gate-recesses and one of the gates remain in situ, to demonstrate the size of the former lock. The nearest Docklands Light Railway station is Limehouse.

Commercial Road Lock
Commercial Road Lock is a lock on the Regent's Canal in the London Borough of Tower Hamlets. It marks the point at which the canal enters Limehouse Basin, and is the penultimate lock before the canal reaches the Thames. The nearest Docklands Light Railway station is Limehouse.

Camden Lock
Camden Lock is a small part of Camden Town, London Borough of Camden, England, which was formerly a wharf with stables on the Regent's Canal. It is immediately to the north of Hampstead Road Locks, a twin manually operated lock. The twin locks together are "Hampstead Road Lock 1"; each bears a sign so marked. Hawley Lock and Kentish Town Lock are a short distance away to the east; to the west is a long level pound (also known as tract or reach) — it is to the next lock. History Regent's Canal was authorised by an Act of Parliament obtained on 13 July 1812, for a canal from Paddington to Limehouse. When the directors first met, they had decided that all locks would be paired, so that some of the water from a lock emptying could be used to fill the adjacent chamber. Water saving was an important factor, as they knew that water supply would be problematic. Colonel William Congreve, a military engineer who was later knighted, proposed the use of hydropneumatic boat lifts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 acc ...

Watford Locks
Watford Locks () is a group of seven locks on the Leicester Line of the Grand Union Canal, in Northamptonshire, England, famous for the Watford Gap service area. The locks are formed (looking from the south), of two single locks, a staircase of four, and a final single lock. Together they lift the canal to the "Leicester Summit", which it maintains all the way to Foxton Locks. The four staircase locks are equipped with working side ponds which are used to save water. The locks were built to carry narrowboats, and the system was opened in 1814. In the early 20th century there were plans to build an inclined plane similar to that at Foxton as part of a scheme to allow the passage of barges, but the plan was abandoned when the inclined plane at Foxton proved uneconomic. When the Grand Union Canal was formed in 1929, there were further proposals to widen the flight as part of the modernisation going on elsewhere on the Grand Union's network, but these plans did not develop furt ...

Rochdale Canal
The Rochdale Canal is in Northern England, between Manchester and Sowerby Bridge, part of the connected system of the canals of Great Britain. Its name refers to the town of Rochdale through which it passes. The Rochdale is a broad canal because its locks are wide enough to allow vessels of width. The canal runs for across the Pennines from the Bridgewater Canal at Castlefield Basin in Manchester to join the Calder and Hebble Navigation at Sowerby Bridge in West Yorkshire. As built, the canal had 92 locks. Whilst the traditional lock numbering has been retained on all restored locks, and on the relocated locks, the canal now has 91. Locks 3 and 4 have been replaced with a single deep lock, Tuel Lane Lock, which is numbered 3/4. History The Rochdale Canal was conceived in 1776, when a group of 48 men from Rochdale raised £237 and commissioned James Brindley to conduct a survey of possible routes between Sowerby Bridge and Manchester. Brindley proposed a route similar to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
