Zimmerberg Tunnel
The Zimmerberg Base Tunnel (ZBT) is a railway tunnel under the Zimmerberg mountains in Switzerland. Phase I of the tunnel was opened to traffic during April 2003. The ZBT has been divided into two phases of work; as of 2020, only Phase I is operational while Phase II remains in the planning and preparation stages. Zimmerberg I is about 10 km long and links Zurich with Thalwil and bypasses a section of the Lake Zürich left-bank railway line, allowing rail traffic to traverse the mountains more efficiently than traditional routes. Phase I During the 1990s, Switzerland embarked upon a major programme of modernisation and improvements across its railway infrastructure. The NRLA initiative sought to provide better alternatives to the steep mountain railways across Gotthard, Ceneri and Lötschberg through the construction of a number of base-level tunnels that enabled trains to more rapidly and efficiently traverse the Swiss Alps. The Zimmerberg Base Tunnel (ZBT) was one such t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gotthard Line
The Gotthard railway (german: Gotthardbahn; it, Ferrovia del Gottardo) is the Swiss trans-alpine railway line from northern Switzerland to the canton of Ticino. The line forms a major part of an important international railway link between northern and southern Europe, especially on the Rotterdam-Basel-Genoa corridor. The Gotthard Railway Company (german: Gotthardbahn-Gesellschaft) was the former private railway company which financed the construction of, and originally operated, that line. The railway comprises an international main line through Switzerland from Basel (French Bâle) or Zürich to Immensee to Chiasso, together with branches, from Immensee to Lucerne and Rotkreuz, from Arth-Goldau to Zug, and from Bellinzona to Chiasso, via Locarno and Luino. The main line, second highest standard railway in Switzerland, penetrates the Alps by means of the Gotthard Tunnel at above sea level. The line then descends as far as Bellinzona, at above sea level, before climbing aga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grout
Grout is a dense fluid which hardens to fill gaps or used as reinforcement in existing structures. Grout is generally a mixture of water, cement and sand, and is employed in pressure grouting, embedding rebar in masonry walls, connecting sections of pre-cast concrete, filling voids, and sealing joints such as those between tiles. Common uses for grout in the household include filling in tiles of shower floors and kitchen tiles. It is often color tinted when it has to be kept visible and sometimes includes fine gravel when being used to fill large spaces (such as the cores of concrete blocks). Unlike other structural pastes such as plaster or joint compound, correctly mixed and applied grout forms a water resistant seal. Although both grout and its close relative mortar are applied as a thick emulsion and harden over time, grout is distinguished by its low viscosity and lack of lime (added to mortar for pliability); grout is thin so it flows readily into gaps, while mortar is ...

Railway Tunnels In Switzerland
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer faciliti ...

Treno Alta Velocità
Treno Alta Velocità SpA (TAV) is special-purpose entity owned by Rete Ferroviaria Italiana (itself owned by Ferrovie dello Stato Italiane) for the planning and construction of a high-speed rail network in Italy. Purpose The purpose of Treno Alta Velocità is the construction of dedicated high speed rail corridors where conventional lines are already saturated. First focus was the Milan to Salerno and the Turin to Trieste corridors. The aims of the project include: aligning the operations of the Italian rail network to European rail standards; expanding the availability of high-speed rail throughout the country thus improving travel times between Italy's major cities; substantially increasing line capacities and train frequencies, and enhancing safety through updates in train control and signaling. Italy's new high speed lines will be used principally for passenger services during the day (AV – Alta Velocità, ''High-speed'') and for freight (AC – Alta Capacità, ''High-c ...

Ceneri Base Tunnel
The Ceneri Base Tunnel (CBT, it, Galleria di base del Monte Ceneri) is a Swiss railway base tunnel in the canton of Ticino. It passes under Monte Ceneri between Camorino in the Magadino Flat and Vezia near Lugano; it bypasses the former high-altitude rail route through the Monte Ceneri Tunnel. It is composed of two single-track tunnels, each long. It is part of the New Railway Link through the Alps (NRLA) project for faster north-south rail links across the Swiss Alps. An exploration tunnel near Sigirino was excavated between 1999 and 2003 to gain geological data on the rock formations at the Ceneri Base Tunnel's level. Based on those data, it was decided to excavate most of the tunnel with traditional blasting methods and only drill a small part using a faster tunnel boring machine (TBM). Both the CBT and Gotthard Base Tunnels were built under contract from the Swiss Federal Government by ''Alptransit Gotthard AG''. Construction of the two single-track bores started during ...

Slurry
A slurry is a mixture of denser solids suspended in liquid, usually water. The most common use of slurry is as a means of transporting solids or separating minerals, the liquid being a carrier that is pumped on a device such as a centrifugal pump. The size of solid particles may vary from 1 micrometre up to hundreds of millimetres. The particles may settle below a certain transport velocity and the mixture can behave like a Newtonian or non-Newtonian fluid. Depending on the mixture, the slurry may be abrasive and/or corrosive. Examples Examples of slurries include: *Cement slurry, a mixture of cement, water, and assorted dry and liquid additives used in the petroleum and other industries *Soil/cement slurry, also called Controlled Low-Strength Material (CLSM), flowable fill, controlled density fill, flowable mortar, plastic soil-cement, K-Krete, and other names *A mixture of thickening agent, oxidizers, and water used to form a gel explosive *A mixture of pyroclastic material, ...
