Heathrow Cargo Tunnel
The Heathrow Cargo Tunnel is a road tunnel in the London Borough of Hillingdon, London, UK that serves London Heathrow Airport. History In December 1968, the tunnel first opened, to connect Terminals 1, 2 and 3 to the newly opened cargo terminal at Heathrow, and it cost £2 million to build. The tunnel is not open to the public; it is used only by vehicles with security clearance to drive airside. It is used for cargo movements, and transfer of passengers to and from Terminal 4 (In 1986, Terminal 4 was built next to the cargo terminal). From 1972, a London Transport bus service (route 82) operated through the tunnel. In 1986, when Terminal 4 opened, a number of other bus routes then also passed through the tunnel. This was an unusual situation, because anyone could board the bus, and travel "airside" without going through any security checks. In 1989, in the interests of security, all public bus services were withdrawn from the tunnel. All public buses now enter the ...

Heathrow Airport
Heathrow Airport (), called ''London Airport'' until 1966 and now known as London Heathrow , is a major international airport in London, England. It is the largest of the six international airports in the London airport system (the others being Gatwick, City, Luton, Stansted and Southend). The airport facility is owned and operated by Heathrow Airport Holdings. In 2021, it was the seventh-busiest airport in the world by international passenger traffic and eighth-busiest in Europe by total passenger traffic. Heathrow was founded as a small airfield in 1929 but was developed into a much larger airport after World War II. The airport lies west of Central London on a site that covers . It was gradually expanded over seventy-five years and now has two parallel east-west runways, four operational passengers terminals and one cargo terminal.

Tunnels In London
A tunnel is an underground passageway, dug through surrounding soil, earth or rock, and enclosed except for the entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sewers or aqueducts to supply water for consumption or for hydroelectric stations. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passage of people and equipment. Secret tunnels are built for military purposes, or by civilians for smuggling of weapons, contraband, or people. Special tunnels, such as wildlife crossings, are built to allow wildlife to cross human-made barriers safely. Tunne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Transport In The London Borough Of Hillingdon
Transport (in British English), or transportation (in American English), is the intentional movement of humans, animals, and goods from one location to another. Modes of transport include air, land (rail and road), water, cable, pipeline, and space. The field can be divided into infrastructure, vehicles, and operations. Transport enables human trade, which is essential for the development of civilizations. Transport infrastructure consists of both fixed installations, including roads, railways, airways, waterways, canals, and pipelines, and terminals such as airports, railway stations, bus stations, warehouses, trucking terminals, refueling depots (including fueling docks and fuel stations), and seaports. Terminals may be used both for interchange of passengers and cargo and for maintenance. Means of transport are any of the different kinds of transport facilities used to carry people or cargo. They may include vehicles, riding animals, and pack animals. Vehicles may incl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Road Tunnels In England
A road is a linear way for the conveyance of traffic that mostly has an improved surface for use by vehicles (motorized and non-motorized) and pedestrians. Unlike streets, the main function of roads is transportation. There are many types of roads, including parkways, avenues, controlled-access highways (freeways, motorways, and expressways), tollways, interstates, highways, thoroughfares, and local roads. The primary features of roads include lanes, sidewalks (pavement), roadways (carriageways), medians, shoulders, verges, bike paths (cycle paths), and shared-use paths. Definitions Historically many roads were simply recognizable routes without any formal construction or some maintenance. The Organization for Economic Co-operation and Development (OECD) defines a road as "a line of communication (travelled way) using a stabilized base other than rails or air strips open to public traffic, primarily for the use of road motor vehicles running on their own wheels", whi ...

Buildings And Structures At Heathrow Airport
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heathrow Airside Road Tunnel
The Heathrow Airside Road Tunnel (ART) is a tunnel at Heathrow Airport. It connects the airside roads around Terminals 1, 2 and 3 to those around Terminal 5. The tunnel was opened to traffic in March 2005 and is used only by vehicles with security clearance to drive airside. The ART is long, consisting of of twin-cell cut and cover box at each end, linked by a pair of long bored tunnels. The ART was designed and built between 1999 and 2004 by a team of engineers from the BAA (the tunnel's owner), Amec, Laing O'Rourke, Morgan Est- Vinci and Mott MacDonald. The bored tunnels have internal diameter of and were driven by a diameter Herrenknecht earth pressure balance tunnel boring machine. The excavations were lined with a bolted concrete lining thick: these are unusually strong tunnel segments, required because the ART is so close to the surface and, at one point, passes over the top of the Heathrow Express Heathrow Express is a high-frequency airport rail link o ...

Taylor Woodrow
Taylor Woodrow was one of the largest housebuilding and general construction companies in Britain. It was listed on the London Stock Exchange and was a constituent of the FTSE 100 Index until its merger with rival George Wimpey to create Taylor Wimpey on 3 July 2007. History Early years Frank Taylor was working in the family fruit wholesaling business in Blackpool when, in 1921, at the age of 16, he persuaded his father that he could build a house for them to live in. With some capital from his father and a loan from the bank, Frank Taylor built a pair of semi detached houses, selling one at a good profit. It was only after financing Taylor's growing housebuilding work for another two years that the bank manager realised that his client was under the legal age for conveying land and uncle Jack Woodrow was brought into the business, creating the Taylor Woodrow name. In 1930, Frank Taylor moved down from Blackpool to London where Taylor Woodrow rapidly expanded the scale of i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tunnel Boring Machine
A tunnel boring machine (TBM), also known as a "mole", is a machine used to excavate tunnels with a circular cross section through a variety of soil and rock strata. They may also be used for microtunneling. They can be designed to bore through hard rock, wet or dry soil, or sand. Tunnel diameters can range from (micro-TBMs) to to date. Tunnels of less than a metre or so in diameter are typically done using trenchless construction methods or horizontal directional drilling rather than TBMs. TBMs can be designed to excavate non-circular tunnels, including u-shaped, horseshoe, square or rectangular tunnels. Tunnel boring machines are used as an alternative to drilling and blasting (D&B) methods in rock and conventional "hand mining" in soil. TBMs have the advantages of limiting the disturbance to the surrounding ground and producing a smooth tunnel wall. This significantly reduces the cost of lining the tunnel, and makes them suitable to use in urban areas. The major disadvan ...

Sump
A sump is a low space that collects often undesirable liquids such as water or chemicals. A sump can also be an infiltration basin used to manage surface runoff water and recharge underground aquifers. Sump can also refer to an area in a cave where an underground flow of water exits the cave into the earth. Examples One common example of a sump is the lowest point in a basement, into which flows water that seeps in from outside. If this is a regular problem, a sump pump that moves the water outside of the house may be used. Another example is the oil pan of an engine. The oil is used to lubricate the engine's moving parts and it pools in a reservoir known as its sump, at the bottom of the engine. Use of a sump requires the engine to be mounted slightly higher to make space for it. Often though, oil in the sump can slosh during hard cornering, starving the oil pump. For these reasons, racing motorcycles and piston aircraft engines are "dry sumped" using scavenge pumps and a s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
