• Walk on the storm sewer

Today, I want to tell you what's going on under your feet. Show the scale of buildings and open their eyes to the underworld. All photos were taken personally in Volgograd, as an example, and it goes the story

How often do you think about the fact that under your feet? that is under the hatches to which you constantly come?

I think that no one cares. Under the ground is buried a lot of secrets, but today let's talk about the storm water drain. All we see every day in the drain grating curbs on the roads, they are the beginning of a large drainage system

Almost under each road laid pipes with a diameter of 30 cm, this is the beginning of the system to these pipes by gratings are perpendicular to the tube of smaller diameter. Water getting into the bars, flows into the main pipe under the road. When the calculated amount of water exceeds the capacity, the pipe diameter increases. So the pipe goes up to the intersection with another collector of larger diameter, which is carried out and drain. Thus by increasing the pipe diameter and grows up to the main pressure reservoir and which is enormous and very dangerous. Some systems now and see. Tsaritsynskaya storm system includes a main tunnel of the underground river of the Queen of 4 by 4 meters, a length of 1.8 km, two major tributaries: Krasnoznamensky collector diameter of 1.5 meters, 800 meters long and Tsaritsyno rainwater collector with a diameter 1.8 meters and 1.7 km long, as there is about sex hundreds of small podklyuchek

Elshanskaya collector. Interesting system of shield tunneling, deep foundations, with a diameter of 4 meters or more. The length of over 1.7 km. It passes directly under the residential areas and below the subway tunnels. It receives water from the street network, ground water and underground water with a road tunnel Start pompous. 7-meter-high arch in the style of Stalin's empire

White River. A huge system, and a very beautiful old + site about 200 years. The main tunnel - 3 km, podklyuchka - 700 meters, the main tributary - 2.5 km
