Features of the Construction of Railway Bridges

The construction of bridges usually begins with the creation of a project for the future construction. Despite the fact that bridges are among the oldest inventions of mankind, and the technology of their construction has significantly improved during the scientific revolution, a simple design process can not be called. It is necessary to take into account a lot of specific details that are irrelevant, for example, when creating cottages and houses.
For the construction will have to study the construction equipment market, find out what the price of concrete mixers and other equipment. After all, when constructing a structure of this type requires a wide range of work. Requires concrete mortar, reinforced concrete blocks, steel elements, metal parts. The duration of the construction process depends on the design of the bridge. Popular beam versions, although sometimes used arched and even block.
The railway bridge is a special object. And the architect must remember this. He creates a project taking into account the characteristics of the terrain, known circumstances of operation, etc. Every day dozens of multi-tonnage trains with passengers and cargo will pass through the bridge. Hence, the design should be sufficiently stable and strong to withstand such loads and not deform.
Special requirements are imposed on the rails - they should be evenly supported by a steel support. If in the road bridges the load can act on different segments of the canvas, then the train travels along the prescribed trajectory and evenly presses on all sections. Therefore, such bridges should have a margin of reliability and durability.
In this case, do not forget one more important point. As the trains move along the standard canvas, without deviating in the way, it is necessary that it has a low threshold of deformation. After all, railroads need a clear path without deformations, cracks, defects, deviations. This ensures the safety of the structure and the speed of transportation.
An important material in the construction of bridges for the railway is steel. It can withstand heavy loads and do not break. Therefore, steel supports and support elements, span structures and even fastenings in the form of bolts and screws. Some parts are made of reinforced concrete, if it is allowed by the architectural design. To implement such complex tasks it is necessary that such road machinery as concrete mixers, loaders in Krasnodar or in other regions be manned and efficient. Because of its quality depends on the safety of construction and construction.
