Wendover Dean Viaduct
The Wendover Dean Viaduct is a railway viaduct currently under construction that will carry the High Speed 2 (HS2) railway line across farmland between Wendover and Great Missenden, Buckinghamshire, England. Approval for the viaduct's construction was issued in 2017 via the High Speed Rail (London - West Midlands) Act 2017; its design was publicly revealed two years later. In June 2021, Buckinghamshire Council also approved plans for the viaduct. Design revisions centred around improving its aesthetics and minimising its impact on the countryside. Construction of the main deck took place between late 2021 and 2024, although high speed trains will not traverse the structure until several years after this point. History Authorisation to construct the Wendover Dean Viaduct was granted, along with the rest of the first phase of HS2, by the High Speed Rail (London - West Midlands) Act 2017. The near-finalised designs of both the Wendover Dean Viaduct and the neighbouring Small Dean Vi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High Speed 2
High Speed 2 (HS2) is a high-speed railway which has been under construction in England since 2019. The line's planned route is between Handsacre – in southern Staffordshire – and London, with a Spur line, branch to Birmingham. HS2 is to be Britain's second purpose-built High-speed rail in the United Kingdom, high-speed railway (after High Speed 1, the London to Channel Tunnel link). London and Birmingham are to be served directly by new high-speed track. Services to Glasgow, Liverpool, and Manchester are to use a mix of new high-speed track and the existing West Coast Main Line. The majority of the project is planned to be completed by 2033. The new track is being built between London Euston railway station, London Euston and Handsacre, near Lichfield in southern Staffordshire, where a junction connects HS2 to the north-south West Coast Main Line. New stations are planned for Old Oak Common railway station, Old Oak Common in northwest London, Birmingham Interchange railw ...

Girder
A girder () is a Beam (structure), beam used in construction. It is the main horizontal support of a structure which supports smaller beams. Girders often have an I-beam cross section composed of two load-bearing ''flanges'' separated by a stabilizing ''web'', but may also have a box girder, box shape, Z shape, or other forms. Girders are commonly used to build bridges. A girt is a vertically aligned girder placed to resist shear loads. Small steel girders are Rolling (metalworking), rolled into shape. Larger girders (1 m/3 feet deep or more) are made as plate girders, welded or bolted together from separate pieces of steel plate. The Warren truss, Warren type girder replaces the solid web with an open latticework truss between the flanges. This arrangement combines strength with economy of materials, minimizing weight and thereby reducing loads and expense. Patented in 1848 by its designers James Warren (engineer), James Warren and Willoughby Theobald Monzani, its st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reinforced Concrete
Reinforced concrete, also called ferroconcrete or ferro-concrete, is a composite material in which concrete's relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel reinforcing bars (known as rebar) and is usually embedded passively in the concrete before the concrete sets. However, post-tensioning is also employed as a technique to reinforce the concrete. In terms of volume used annually, it is one of the most common engineering materials. In corrosion engineering terms, when designed correctly, the alkalinity of the concrete protects the steel rebar from corrosion. Description Reinforcing schemes are generally designed to resist tensile stresses in particular regions of the concrete that might cause unacceptable cracking and/or structural failure. Modern reinforced concrete can contain varied reinforcing materials made o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
A413 Road
The A413 is a major road in England that runs between Denham (west of London) to Towcester (northwest of Milton Keynes). It passes through or near various towns and villages including (in northbound order) Gerrards Cross, Chalfont St Peter, Chalfont St Giles, Amersham, Little Missenden, Great Missenden, Wendover, Aylesbury, Winslow, and Buckingham. Most of the road is in Buckinghamshire, with a part at the north end in Northamptonshire. In the 1960s, a by-pass was built around Great Missenden and re-routing has taken place through Aylesbury town centre. In recent years , by-passes have been built for Amersham (1987) and Wendover (1998). In the early 21st century, the junction near Towcester where the A413 joins the A43 has also been redeveloped along with much-needed A43 redevelopment around Silverstone Circuit. That part of the route which runs along the Misbourne Valley dates back into pre-history. In medieval times, the Cartulary of Missenden Abbey simply record ...

Chiltern Tunnel
The Chiltern Tunnel is a high-speed railway tunnel currently under construction in Buckinghamshire and Hertfordshire, England, and will upon completion carry the High Speed 2 (HS2) railway line under the Chiltern Hills. The twin-bore tunnels, which are long, will be the longest on the HS2 line. Each tunnel will also have additional entry and exit perforated concrete portals to reduce sudden changes in air pressure and subsequent noise. A contract for the tunnel's construction was awarded in 2017; preparatory work commenced during the following year. In May 2021, it was announced that excavation had commenced. The boring process, which was largely performed by a pair of tunnel boring machines (TBMs), advanced at an average speed of per day; both TBMs completed their drives by March 2024. History The construction of the High Speed 2 (HS2) railway involves numerous major civil engineering works along its intended route, with construction periodical ''New Civil Engineer'' descr ...

Joint Venture
A joint venture (JV) is a business entity created by two or more parties, generally characterized by shared ownership, shared returns and risks, and shared governance. Companies typically pursue joint ventures for one of four reasons: to access a new market, particularly emerging market; to gain scale efficiencies by combining assets and operations; to share risk for major investments or projects; or to access skills and capabilities.' Most joint ventures are incorporated, although some, as in the oil and gas industry, are "unincorporated" joint ventures that mimic a corporate entity. With individuals, when two or more persons come together to form a temporary partnership for the purpose of carrying out a particular project, such partnership can also be called a joint venture where the parties are "''co-venturers''". A joint venture can take the form of a business. It can also take the form of a project or asset JV, created for the purpose of pursuing one specific project, ...

Great Missenden
Great Missenden is a village and civil parish in the Misbourne Valley in the Chiltern Hills in Buckinghamshire, England, situated between the towns of Amersham and Wendover. It adjoins the village of Little Kingshill, and is a mile from Little Missenden and the village of Prestwood. The narrow and historic High Street is bypassed by the main A413 London to Aylesbury Road. It is located in the centre of the Chilterns Area of Outstanding Natural Beauty. The source of the Misbourne is to be found just north of the village, although the upper reach of the river runs only in winter and the perennial head is in Little Missenden.
