Bridge over flowing river: - How a bridge is built over a flowing river, learn interesting facts

Bridges are built to cross the river. Today there is no such river over which a bridge is not built. India is setting a new record every day on the path of development. There is no state in India where roads and bridges have not been constructed. Although there will be lakhs of bridges in India, there are some such bridges whose construction is no less than pride for India.

If you live across the Yamuna, you must have passed through the iron bridge or perhaps heard the name. But even this question has come to your mind how the pillar is made over the flowing river? How is a bridge erected by reaching the depth of the river? If you do not know, then today we answer the same questions of yours.

Research is done first

Bridges on the river are made in many ways and the method of making the bridge is also different. But research is done before building a bridge. In research, research is done on the depth of water, speed of flow of water, research on soil under water, the weight of the bridge, weight after construction of bridge, cost and size.

The foundation of the bridge is laid

Very few people know that the Cofferdam style is used to build bridges over water. Explain that a cofferdam is an enclosure that is made to stop the water. This style is commonly used for the construction of permanent underwater dams, oil platforms, and bridge piers.

In this, it is installed in the middle of the water by means of a drum or crane etc. It is made through large plates of steel. However, their shape may be different.

Bridge gets ready after years

Sounds easy to us, but it take years to build a bridge. If the bridge is made of iron, then before making it, big iron pipes are taken to the place of contraction with the help of a ship.

Then these pipes are buried under water by machines, over which the work of building a bridge is started.

These things are used

Materials such as steel, concrete, stone and asphalt are used to make a bridge. Iron, wood, aluminium, rubber and other materials are also included. To build the bridge, most of the effort is spent on erecting the pillars inside the water. After this, the bridge is easily erected.
