Suplacu De Barcău Viaduct
The Suplacu de Barcău Viaduct () is a future viaduct between Suplacu de Barcău and Borș, Romania. 90% of its course is already built. The remaining part was abandoned by the American company Bechtel, on the route of the future A3 Transylvania Motorway. Suplacu de Barcău viaduct is the largest structure along the length of the Transylvania Motorway and will be, once completed, the largest viaduct in southeast Europe. The viaduct will be a traditional piled structure with a length of and 45 spans of . To build this structure will require of concrete, 6.5 tonnes of reinforcement steel, and 1.3 tonnes of stressing cable, 360 pre-cast U-beams each weighing 160 tonnes. Construction work at the viaduct is underway and includes foundation activities, piling installation, reinforcement of concrete pile caps, pier elevations and pier heads. The next phase of construction will involve the U-Beam installation and afterwards, once the U-beams are installed, the placement of the deck ...

Suplacu De Barcău
Suplacu de Barcău (, ) is a Commune in Romania, commune in Bihor County, Crișana, Romania with a population of 3,813 as of 2021. It is composed of six villages: Borumlaca (''Baromlak''), Dolea (''Dólyapuszta''), Foglaș (''Fogás''; ''Fogaš''), Suplacu de Barcău, Valea Cerului (''Cserpatak''), and Vâlcelele (''Blágarét''). History The two oldest villages in the commune, Suplacu de Barcău and Borumlaca, were partly depopulated between 1686 and 1692, as a result of the Great Turkish War; the previous inhabitants began to return once hostilities ceased. Numerous families of Slovak colonists arrived in the late 18th century, leading to the appearance of two other villages, Vâlcelele and Valea Cerului. The final two, Dolea and Foglaș, date to 1905 and 1916, respectively.''Istoria...'', p. 99 Natives *Iuliu Hajnal (born 1951), footballer See also * Suplacu de Barcău Viaduct Notes References * Gruia Fazecaș, Doru Marta, Gabriel Moisa, Nicolae Tivadar''Istoria comunei Su ...

Rebar
Rebar (short for reinforcement bar or reinforcing bar), known when massed as reinforcing steel or steel reinforcement, is a tension device added to concrete to form ''reinforced concrete'' and reinforced masonry structures to strengthen and aid the concrete under tension. Concrete is strong under compression, but has low tensile strength. Rebar usually consists of steel bars which significantly increase the tensile strength of the structure. Rebar surfaces feature a continuous series of ribs, lugs or indentations to promote a better bond with the concrete and reduce the risk of slippage. The most common type of rebar is carbon steel, typically consisting of hot-rolled round bars with deformation patterns embossed into its surface. Steel and concrete have similar coefficients of thermal expansion, so a concrete structural member reinforced with steel will experience minimal differential stress as the temperature changes. Other readily available types of rebar are manufacture ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pile Cap
A pile cap is a thick concrete mat that rests on concrete or timber piles that have been driven into soft or unstable ground to provide a suitable stable foundation. It usually forms part of the deep foundation of a building, typically a multi-story building, structure or support base for heavy equipment, or of a bridge. The cast concrete pile cap distributes the load of the building into the piles. A similar structure to a pile cap is a "raft", which is a concrete foundation floor resting directly onto soft soil which may be liable to subsidence. Design Construction The mat is made of concrete which is an aggregate of small rocks and cement. This mixture has to be supported by a framework to avoid sagging and fracture while setting. This process is known as shuttering and reinforcing. The materials used are long steel bars with longitudinal protrusions between the piles held in shape by thinner tie wires. Once this steel mat is laid, timber is attached around the perimeter t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foundation (engineering)
In engineering, a foundation is the element of a structural engineering, structure which connects it to the ground or more rarely, water (as with Floating building, floating structures), transferring force, loads from the structure to the ground. Foundations are generally considered either Shallow foundation, shallow or Deep foundation, deep. Foundation engineering is the application of soil mechanics and rock mechanics (geotechnical engineering) in the design of foundation elements of structures. Purpose Foundations provide the structure's stability from the ground: * To distribute the weight of the structure over a large area in order to avoid overloading the underlying soil (possibly causing unequal settlement). * To anchor the structure against natural forces including earthquakes, floods, droughts, frost heaves, tornadoes and wind. * To provide a level surface for construction. * To anchor the structure deeply into the ground, increasing its stability and preventing over ...

Wire Rope
Steel wire rope (right hand lang lay) Wire rope is composed of as few as two solid, metal wires twisted into a helix that forms a composite ''rope'', in a pattern known as ''laid rope''. Larger diameter wire rope consists of multiple strands of such laid rope in a pattern known as ''cable laid''. Manufactured using an industrial machine known as a strander, the wires are fed through a series of barrels and spun into their final composite orientation. In stricter senses, the term ''wire rope'' refers to a diameter larger than , with smaller gauges designated cable or cords. Initially wrought iron wires were used, but today steel is the main material used for wire ropes. Historically, wire rope evolved from wrought iron chains, which had a record of mechanical failure. While flaws in chain links or solid steel bars can lead to catastrophic failure A catastrophic failure is a sudden and total failure from which recovery is impossible. Catastrophic failures often lead to cascadi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Concrete
Concrete is a composite material composed of aggregate bound together with a fluid cement that cures to a solid over time. It is the second-most-used substance (after water), the most–widely used building material, and the most-manufactured material in the world. When aggregate is mixed with dry Portland cement and water, the mixture forms a fluid slurry that can be poured and molded into shape. The cement reacts with the water through a process called hydration, which hardens it after several hours to form a solid matrix that binds the materials together into a durable stone-like material with various uses. This time allows concrete to not only be cast in forms, but also to have a variety of tooled processes performed. The hydration process is exothermic, which means that ambient temperature plays a significant role in how long it takes concrete to set. Often, additives (such as pozzolans or superplasticizers) are included in the mixture to improve the physical prop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
