Hoover Dam Bridge Construction

Motivation for my work that lies ahead this week… My dream is to someday be part of such a breathtaking project!!! But for now…

PLEASE NOTE: – – – THESE PHOTOS ARE NOT MY OWN&HAVE IN NO WAY BEEN EDITED BY ME!!! I got these pics via email, thus unknown photographer!!! But… I must say well done!!! Awesome photography… Awesome structure… What’s not to love??

Photographer known!!!!! Thank you so much to http://barkumephotography.wordpress.com/ for informing me of who the photographer for these great photographs were!!! Thank you JAMES STILLINGS (click to follow link to his website – – – Awesome!!!) !!!

Yet another engineering feat!!! Definitely on my list of places to visit!!! Have you been there yet?? 🙂 Beautiful!!!!! **

Builders in the sky!!!

Workers build a footpath around the vertiginous slopes of Shifou Mountain in China!!

Thousands of metres up the vertiginous slopes of Shifou Mountain in Hunan Province, China, a team of workers, operating with hardly any safety measures, are building a footpath.

The workers are building a plank road on the side of the mountain that, once it is finished, will stretch for 3km (9843 ft) and be China’s longest sightseeing footpath.

48-year-old Yu Ji (above) is one of the workers and he has been working on high cliffs building such plank roads for more than 10 years. He comments: “Young people don’t want this job, as it requires them to stay deep in the mountains for months or even years”

Yu Ji takes charge of the most dangerous part of the project – drilling the holes to set up pipes to support the footpath.
Building a plank road on Shifou Mountain is difficult because the cliff stands vertical at 90 degrees, without any slope or alcoves.

A finished section of the footpath.

Loving it!! 🙂 – – – Hope you did too – – – **

River OVER a river!!! – – – Magdeburg Water Bridge, Germany – – –

Water Bridge in Germany.   What a feat!!!

Six years, 500 million euros, 918 meters long . . . now this is engineering!

This is a channel-bridge over the River Elbe and joins the former East and West Germany, as part of the unification project. It is located in the city of Magdeburg , near Berlin.
The photo was taken on the day of inauguration . . .To those who appreciate engineering projects, here’s a puzzle for you armchair engineers . . ..  and physicists: Did that bridge have to be designed to withstand the additional weight of ship and barge traffic, or just the weight of the water?

Answer: It only needs to be designed to withstand the weight of  the water!

Why?  A ship always displaces an amount of water that weighs the same as the ship, regardless of how heavily a ship may be loaded.

The Magdeburg Water Bridge is a navigable aqueduct in Germany that connects the Elbe-Havel Canal to the Mittelland Canal, and allows ships to cross over the Elbe River. At 918 meters, it is the longest navigable aqueduct in the world.

The Elbe-Havel and Mittelland canals had previously met near Magdeburg but on opposite sides of the Elbe. Ships moving between the two had to make a 12-kilometer detour, descending from the Mittelland Canal through the Rothensee boat lift into the Elbe, then sailing downstream on the river, before entering the Elbe-Havel Canal through Niegripp lock. Low water levels in the Elbe often prevented fully laden canal barges from making this crossing, requiring time-consuming off-loading of cargo.

Construction of the water link was started as early as in the 1930s but due to the World War 2 and subsequent division of Germany the work remained suspended till 1997. The aqueduct was finally completed and opened to the public in 2003.

So, I definitely want to visit Germany now!! Got to love engineering!! 😀 **

 

Longest Bridge opens in China… WOW!!!

Being a structural engineer I found this truly spectacular. Couldn’t resist the urge to show you yet another engineering feat — Truly amazing!! Njoy!!! (Source: personal email)

World’s longest sea bridge opens in China… (but don’t think about crossing it on foot, it’s the length of a marathon)

  • At 26.4 miles long, it is five miles further than the distance between Dover and Calais

China has opened the world’s longest cross-sea bridge – which stretches five miles further than the distance between Dover and Calais.

The Jiaozhou Bay bridge is 26.4 miles long and links China’s eastern port city of Qingdao to the offshore island Huangdao.

The road bridge, which is 110ft wide and is the longest of its kind, cost nearly £1billion to build.

A bridge over misty waters: The immense £1billion structure which is supported by more than 5,000 pillars stretches for 24 miles along China’s eastern port city of Qingdao to the offshore island Huangdao

Engineering feat: The vast bridge, the largest cross-ocean bridge in the world, cost £960million and took four years to build

Lengthy: The bridge stretches into the distance further than the eye can see and right, the first few cars roll out across the surface

Open road: Drivers pass through the mist as they make some of the first passes over the 110ft wide bridge which is longer than any others of its kind

Don’t keep me hanging: The suspension beams form an imposing sight as the reach through the clouds and look down upon colourful flags marking the bridge’s grand opening

Record breaker: The Qingdao Jiaozhou bay bridge, spanning 26.4 miles between Qingdao and Huangdao, will open for traffic today

Impressive: Testing on the bridge was completed on Monday and it is expected to be opened to traffic for the first time today

A driver’s dream: Twenty-four miles of fresh untouched tarmac stretch from Qingdao to Hungdao

Now how about that? That’s why I love structures!!!
