Marvel of Modern Engineering

Water bridge is new to hear, Yes water bridges is in the world. The most water bridges are from outside India such as UK, Netherlands, France, Germany, Belgium. 

Features of Water Bridges:

• They helps for transporting goods, machinery's, services across rivers & connect such places which are not connected before.
• They are not producing pollution while cars, motors, busses, trucks producing pollution mainly air pollution.
• Looks awesome

Bubble Deck Slab

What is Bubble Deck Slab ?

Bubble deck slab is a method of eleminating all the concrete from middle in-effective portion of slab which is not performing any structural function & reduce the dead load of structure.

Bubble Deck Slab Method:

In the slab, middle portion which is not effective replaces concrete by high density polyethylene hollow spheres. 

Why bubble deck slab ?

• No need of beam.
• Longer spans.
• No compromise for strength and serviceability.
• Pre-fabricated and cast in situ.

Structural Advantage:

• Less weight.
• No need of beams.
• Freedom for choice of shape.
• Larger span.
• Few columns are required.
• Increased strength.
• Less excavation.

Engineering Advantages:

• High resistance against explosion.
• These slab and column system acts as a elastic membrane which transfer horizontal force to stiff vertical structure which is used for earthquake resistant design.

Construction Advantage:

• Light weight & required less equipment.
• Does not require heavy job on site work.
• Reduce foundation size.

Economically Advantage:

• Save material.
• Transportation cost reduced.
• Faster construction time.
• Building can be more flexible & easy in installation.
• Lower workforce. 
• No carpentry.

Environmental Advantages:

• Reducing CO2 emission.
• Less energy consumption.
• 1Kg of plastic replaces 100Kg of concrete.
• Each & every component can be recycled.

Future Uses:

• This method can be used for constructing of scrapper.
• Used for constructing parking deck as less number of columns required.
• Pedestrian bridge deck.
