Pipe Jacking
Pipe ramming (sometimes also called pipe jacking) is a trenchless method for installation of steel pipes and casings. Distances of 30 m (150 feet) or more and over 500 mm (20 inches) in diameter are common, although the method can be used for much longer and larger installations. The method is useful for pipe and casing installations under railway lines and roads, where other trenchless methods could cause subsidence or heaving. The majority of installations are horizontal, although the method can be used for vertical installations. The main differences between pipe ramming and pipe jacking are that pipe ramming uses percussion and does not have a navigation system, while pipe jacking uses hydraulic jacks and does have an active navigation system. Pipe ramming is preferable for shorter distances and applications that do not require tight directional control, such as cable installations. The method uses pneumatic percussive blows to drive the pipe through the ground. The leadi ... [...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 ...

East Link Bridge
The Tom Clarke Bridge (), formerly and commonly known as the East-Link Toll Bridge, is a toll bridge in Dublin, Ireland, on the River Liffey, owned and operated by Dublin City Council. The bascule-type lifting bridge, which links North Wall to Ringsend, is the last bridge on the Liffey, which opens out into Dublin Port and then Dublin Bay just beyond. The bridge forms part of the R131 regional road. Background and use The bridge is the most easterly crossing on the Liffey, and replaced a number of ferries that carried cross-river traffic at the point as early as 1655. The bridge was built by NTR, and opened to vehicular traffic in October 1984. The bridge reverted to city council control on 31 December 2015. The city centre is west of the bridge, which links routes on the eastern side of Dublin city. The Dublin Port Tunnel terminates north of the East-Link along East Wall Road, in the Docklands on the north bank of the Liffey. Most of Dublin's docklands are east of the bridg ...

River Liffey
The River Liffey (Irish: ''An Life'', historically ''An Ruirthe(a)ch'') is a river in eastern Ireland that ultimately flows through the centre of Dublin to its mouth within Dublin Bay. Its major tributaries include the River Dodder, the River Poddle and the River Camac. The river supplies much of Dublin's water and supports a range of recreational activities. Name Ptolemy's ''Geography'' (2nd century AD) described a river, perhaps the Liffey, which he labelled Οβοκα (''Oboka''). Ultimately this led to the name of the River Avoca in County Wicklow. The Liffey was previously named ''An Ruirthech'', meaning "fast (or strong) runner". The word ''Liphe'' (or ''Life'') referred originally to the name of the plain through which the river ran, but eventually came to refer to the river itself. The word may derive from the same root as Welsh ''llif'' (flow, stream), namely Proto-Indo-European ''lē̆i-4'', but Gearóid Mac Eoin has more recently proposed that it may derive from a n ...
