How are bridge pillars constructed?

Cofferdam technique is used in this case. In this method, a wall enclosing an area is build inside the water and water is continuously pumped out from the area. After that, foundation of the bridge(the pillars) is constructed inside the cofferdam. Water filled during this process is pumped out.

How are pillars constructed?

pillar, in architecture and building construction, any isolated, vertical structural member such as a pier, column, or post. It may be constructed of a single piece of stone or wood or built up of units, such as bricks. It may be any shape in cross section.

What type of concrete is used for bridges?

The construction of bridges, fly-overs, heavy-loaded structures requires pre-stressed concrete. Precast concrete – Small units like concrete blocks, poles, concrete lintels, staircase units and precast walls use precast concrete.

How do cofferdams work?

Constructing a cellular cofferdam is done by driving sheet piles in a circular pattern, and then repeating this process adjacent to the original to form a series of circular cells. Each of these cells connects to one another and forms a tight seal that prevents water from entering.

What’s the difference between pillar and column?

A pillar is a vertical support member and may be constructed as a single piece of timber, concrete or steel, or built up out of bricks, blocks and so on. However, whereas a pillar does not necessarily have a load-bearing function, a column is a vertical structural member that is intended to transfer a compressive load.

What holds up a pillar?

A small wooden or metal support is typically called a post, and supports with a rectangular or other non-round section are usually called piers. For the purpose of wind or earthquake engineering, columns may be designed to resist lateral forces.
