Dangerous areas of the capital land

Dangerous areas of the capital landIn one of the capital's households own land, a full sense of the word, opened up under his feet, pulling the trees and all that was on the surface, says "TV Center". The main reasons for failure: the movement of ground water, rotting underground utilities, construction without proper geological studies

Actually last week Muscovites do not just have to hold my breath. Of course, against the background of what is happening now in Japan, our problems may seem small. However, in one of the capital's households own land, a full sense of the word, had opened the windows at home, carrying trees and all that was found on the surface. Failures occurred in the soil before. Artem Konstantinov went in search of the causes and patterns.

Artem Konstantinov, correspondent:

— The fact that only a few days ago, here in this place was a gaping hole in width and a depth of 10, according to one of 7, on the other — 15 m, like today only this striped ribbon. Failure quickly filled with gravel and sand.

Land in the yard of 12/14 opened up in the late evening of March 8. For the past year, very close to elevate business center with three-level underground parking. Emergency on a construction site already happened, only holes were much smaller, and they paid little attention. A massive landslide is alarmed everyone.

— Looked out the window, so the broads down there, I thought fences fell.

Dmitry Mikhaltsov, a resident of house 12/14 to Krasnokazarmennaya street:
— There was a roar, roar of a falling tree. I looked out the window and saw a tree at first declined. Then the second tree fell.

Arriving crews MOE and public utilities cordoned off the area, established a broken heating the time scheme. And the very pit filled, they could. No guarantee that this or next ground does not collapse again — no.

Irina Kazakova, head of the state groundwater monitoring GMSN territorial center in Moscow:
— This requires special study to specialists look. First, look what state foundations of buildings, structures which there is, in any form of communication, and to what depth, and how they are distributed.

This case is not fast, and hardly had the expertise to conduct before the hole in the ground eliminated. Meanwhile, standing near the apartment building, built in the 30's of last century, has crept cracks. Residents fear that the building could collapse. Construction on a dangerous place continues.

In general, then, that in Moscow from time to time something fails, today it is no news. Frightening scale events. Emergency on Krasnokazarmennaya — 31st in the capital over the past 5 years. Went underground section of the street, cars and trucks. Only by sheer luck no one was hurt. How many more places in Moscow, where the land could take under its feet, and do not count. A hole in the arch of the house number 114 to the Trade Union Street residents have long been concerned about.

— Well, 15 years is exactly 20 may be even. And all the time here somehow falls off the asphalt. But in the past year have done here, the workers laid asphalt pieces there, bricks, and then again she has failed. I said: "I go with my children, their grandchildren to school and I am afraid that they will fail in this hole easy."

On asphalt cracks already gone, what ground can "go" at any moment can be seen with the naked eye! Well, all communal promise anything again fill the pit.

Bomb under the city life puts so-called suffusion. In some areas the groundwater wash soil particles are formed cavity, where then everything falls: more often — in the fall or spring.

Vadim Pendina, doctor of geological-mineralogical sciences, professor, academician of the Academy of Natural Sciences:
— Because it starts melting snow, the volume of water that moves under the ground, and as a result of this process is intensified suffusion, and there are gaps.

Water falls to the mill ground literally poured and city sewers. For many years now the pipes of 40 — 50, and they have long been more like a sieve.

Vadim Pendina, doctor of geological-mineralogical sciences, professor, academician of the Academy of Natural Sciences:
— According to conservative estimations percentage leakage is about 15-20 of the water that flows through these pipes here.

No rest and soils from the capital construction. Striving for every piece of land to build any tower, and even better with a 3 — 4 underground levels — "a knife in the back" of the already wounded Moscow land.

Irina Kazakova, head of the state groundwater monitoring GMSN territorial center in Moscow:
— The territory we have built up not only from above, but from below. And maybe even the underground part of the city is built up more than the surface.

Vadim Pendina, doctor of geological-mineralogical sciences, professor, academician of the Academy of Natural Sciences:
— Each of us is immune to the fact that driving along the road, he can fall to the ground. It occurs in all the cities of the world, this is not just a problem of Moscow.

Many cities and countries suffer even more terrible failures — karst. This is when the soil is not washed and chemically dissolved. Hole in the ground caused by this phenomenon in hundreds of meters deep and has a sinister look. The appearance of such a chasm in the Russian capital is unlikely, but there is danger of a karst area in Moscow.

Irina Kazakova, head of the state groundwater monitoring GMSN territorial center in Moscow:
— It is basically Northwestern our district almost all. The so-called plot Khodynskoe there natural conditions are such that there karst processes we have developed, and they are very close to the surface.

This of course does not mean that half of the city will soon collapse into the abyss, but to build in dangerous areas only with the utmost caution. Caution — do keyword. What there is not happening under the ground, if time does not change the pipe, not to deep geological study and monitor the situation, builders expect a complete failure.
