Tour to Hoover Dam Bashny.Net

Today we will focus on a unique structure located on the territory of the United States - Hoover Dam. It is located in the Black Canyon, on the border of Arizona and Nevada, and is today one of the most famous attractions in the vicinity of Las Vegas. The construction of a huge and monumental.
Hoover Dam - concrete gravity-arch dam; water pressure hampered by both the mass wall and bend it, the load on the transmission side of the canyon, while remaining concise.





Sightseeing begins with this place.



Memorial Bridge Mike O'Callaghan - Pat Tillman.
Previously, the road runs through the dam itself, but in 2012, made the new road with a huge arched bridge.

Construction of the dam was carried out under difficult conditions. Part of the work carried out in the tunnels where workers suffered from an excess of carbon monoxide [6] (some workers have become disabled or even killed because of this).
Total for the construction killed 96 people.



The border states, is held right in the middle of the dam.



The dimensions are impressive.
Just a concrete required for construction of the dam, kneaded 600 thousand. Tons of Portland cement and 3, 44 million cubic meters of aggregate.
The process of curing concrete, from which the dam is built, not finished today!

It is white because of deposits of minerals.

Since the operation of such a scale had never been made, a number of technical solutions applied in the construction process, wore unique. One of the problems with which the engineers had a chance encounter, was the cooling of the concrete. Instead of a solid monolith, the dam was built as a series of interrelated pillars in the shape of trapezoids - is allowed to dissipate excessive heat generated during the solidification of the concrete mix.



Mead (reservoir) the largest reservoir in the United States. It is located on the Colorado River about 30 miles (48 km) southeast of Las Vegas.
