The Crimean bridge is on the verge of destruction. The Crimean bridge will collapse soon: the main reasons It is true that the Kerch bridge is destroyed

The Crimean bridge will collapse soon: the main reasons for the rapid collapse of structures that can lead to the death of hundreds of people and the failure of the project to join the peninsula to the mainland.

Putin opened the bridge! And why is everyone happy, someone can explain? Why did this concrete appendix surrender to normal Russians? You won’t go to the sea anyway - it’s expensive, dirty, traffic jams, soviet service. You can't do business there - sanctions, inconvenient location, poor population. How much money will be spent on the maintenance and protection of this bridge - do not count.

But most importantly, why protect something that is doomed to destruction at all? Now you will be given reasons why the Kerch bridge will not stand idle even for 5 years. Be sure to repost this article on the wall, save it in the tabs, distribute it among the residents of your house, so that after a specified period you will be surprised how right the expert was.

Reason #1: Earthquake

Seismic resistance of the Crimean bridge - 9 points. Why was this number chosen? Because the amplitude of the last strong earthquake, which was recorded and measured in the Crimea in 1927, was 8 points. That is, the margin of safety of the structure is only 1 point! How do you like it? At the same time, seismologists predict an earthquake from 7 to 10 points in the Crimea in the next 50 years.

Krymsky bridge bottom view - longitudinal beams on a concrete base

The bridge is almost completely made of monolithic concrete, the floors are laid on longitudinal metal beams. Where it leads? With a strong earthquake, the structure will not “walk”, which will lead to the appearance of cracks, displacement of plates and supports, and subsequent collapse. The space between the beams will collapse, the cars will simply fall into the water. Don't believe? Try to hit stone and iron with a hammer - where will the crack appear first?

Akashi-Kaikyo Bridge in Japan - the metal truss is clearly visible from below

For this reason, the safest place on the Kerch Bridge is the broken marking lines that correspond to the location of the supporting beams. But people are not allowed to ride on them, they are not given the opportunity to save their lives.

Golden Gate Bridge - also has a truss for earthquake resistance

In other countries, in earthquake-prone areas (Japan, San Francisco, etc.), bridges are made arched, mainly from metal, since it is more plastic during tremors. Under the bridge there is a complex metal truss, and even if the canvas cracks, the car will not fall into the water, but will get stuck in it.

Reason #2: mud volcano

Of course, the Krymsky Bridge was not built entirely with felt boots, and the piles were not driven into active mud volcanoes. However, a volcano in the sea is such a thing that today it erupts in one place, and tomorrow in another (see the research of academician Borislavsky "Migration of mud volcanoes").

Why is a mud volcano dangerous? If he wakes up right under the support, then it will be thrown into the air to a height of several tens of meters, scattering cars like matchboxes. If the volcano is activated nearby, then the roadway, which does not have the necessary drainage, can be flooded with mud. In this case, the railway bridge can withstand, but the road bridge simply cannot withstand the load.

US Mud Volcano Nozzle

In America, this problem is solved very simply - next to the bridge, at a distance of two kilometers, the bottom is concreted, exposing a special nozzle for the volcano. During the eruption, all the dirt is sent to the designated place without harming the structure.

In addition, during a volcanic eruption, space is vacated in the geological layers, and water flows there. Accordingly, the support can simply fall down.

Reason number 3: tectonic fault

It is no coincidence that Mother Nature invented the same mud volcanoes, because mud serves as a natural lubricant for the movement of lithospheric plates. The movement of plates around the center of the Earth ensures climate change, the formation of sea currents and wind roses.

Plate joints serve not only to dump excess dirt through volcanoes, but also naturally equalize stress in the earth's crust. Therefore, almost all known countries refused to build in the tectonic fault zone by signing the Lithospheric Memorandum in 1954, and only the USSR ignored this agreement. However, Khrushchev, having transferred the Crimea under the jurisdiction of the Academy of Sciences of the Ukrainian SSR, did this, among other things, for security reasons, continuing Stalin's policy of Ukrainization of the western territories.

The supports of the Crimean bridge can not only fall into a tectonic fault, going underground for several kilometers, but also disrupt the trajectory of the movement of lithospheric plates, which will lead to a large number of natural disasters around the world. Tsunamis, tornadoes, earthquakes, floods are a natural result of shale drilling under the bridge supports.

Reason #4: Impact of Ice and Wind

Throughout the year, the Crimean Bridge is affected by strong winds that destroy concrete. Metal structures are exposed to intense corrosion due to excess salt and faeces of sea loons. In order for the bridge to stand for a long time, it must be protected annually with special mastics and sealants, and the equipment to scare away birds should be maintained, and this is again billions of budget money.

In winter, the bridge supports are affected by ice. It was the ice drift that caused the destruction of the previous bridge in 1945, built by Hitler and restored by the USSR. Moreover, the ice not only loosens the supports driven into the muddy ground, but also freezes on metal structures, increasing the load to extreme values.

Icebreaker Ukraine in the port of Berdyansk

As long as the winters are warm, you can not be afraid of the bridge. But the thickness of the ice in the Kerch Strait can reach 1 meter, and the use of ships is complicated due to the territorial dispute. The icebreaking flotilla remained in the ownership of Ukraine and is moored in the port of Berdyansk, so in order to save the bridge from destruction, sooner or later you will have to bow to President Poroshenko. Ferry of ships from the northern seas will not be economically feasible, and the shipping channel is too small for them.

Reason #5: terrorist attack or military attack

Putin sends the best types of weapons to Crimea, including nuclear ones, which can be easily captured along with the territory by terrorists or simply enemies. In this case, the bridge will be attacked first, as the only supply line from the Russian Federation. The same ferries will not be difficult to sink. How Russian air defense works became clear to everyone after the destruction of the Pantsir complex in Syria, so the only real step is to protect the bridge with the help of balloons and barrier nets.

From the side of the sea, it also makes sense to protect the structure with minefields, gratings, seat agents under the guise of fishermen in order to prevent an attack in time. Again, the beaches in the resort areas should be moved closer to the bridge so that it remains in the zone of attention of citizens.

Now the bridge is guarded, but not so well. It seems that the authorities do not seek to preserve their main treasure, and anyone who wants to is the bomb. Why aren't the Cossacks patrolling the bridge? Why are cars not inspected when entering the bridge, why are there no pillboxes, concrete fortifications, and long-range artillery? Stalin would have shot everyone for such negligence long ago, because this is a strategic object, the same as a mausoleum.

The first footage from the site of the collapse of a fragment of the Crimean bridge appeared on the Web.

An emergency occurred on the Crimean bridge, as a result of which a fragment of the span of the railway part of the structure under construction was in the water. As a result of the incident, no one was injured. The incident did not affect the construction schedule in any way.

According to the information center "Crimean Bridge", one of the spans tilted and collapsed into the water area in shallow water on the offshore section of the construction of the bridge between the Tuzlinskaya Spit and the intkbbee island. This happened during the lowering of the span onto the supports.

Presumably, the incident occurred due to a technical malfunction of one of the jacking systems.

It is known that the bridge supports remained safe and sound, the bearing capacity was not violated.

It is planned that the superstructure that has fallen into the water will be removed by cranes after the necessary preparation.

"In place of the fallen span structure, a new one will be installed. According to preliminary estimates, this will take 30-45 days," the information center said.

Now representatives of the customer and the contractor are working on the site. The consequences of what happened are assessed, the causes are clarified. We add that construction and installation works on the object are insured.

Earlier TopNews that the opening of the Crimean bridge for truck traffic was filmed from a bird's eye view.

Residents of Crimea are worried that the Crimean bridge, which was opened to cars back in May 2018, is simply bursting at the seams. This is reported by eyewitnesses of this situation. According to them, the supports of the Crimean bridge are covered with cracks, which can lead to its collapse. It is known that the bridge construction zone has a high seismological activity, which could affect its current state.

Residents of Crimea are concerned about this state of affairs. The fact of the destruction of the Crimean bridge suggests that the construction would have been carried out improperly. Motorists are afraid that one "perfect" day will be under the water of the Kerch Strait.

Even from the beginning of the construction of the Crimean bridge, which began in 2015 after the transfer of the Crimean peninsula into the hands of the Russian state, experts did not pin their hopes on it. Bridge builders argued that building a bridge across the Kerch Strait was not the best idea, since the area is dangerous for such structures.

After 3 years, from the beginning of construction, this statement about the destruction of the Crimean bridge only speaks of their correctness. The words and photographs of motorists who witnessed these events show the formation of cracks in the bridge's concrete piers. All this despite the fact that its construction has not even been completed yet.

Many admire the work done by the Russian authorities to unite Crimea with their state. However, even the scale of the Crimean bridge and its beautiful appearance cannot overshadow the fact that it can simply be under water at any moment. Maybe along with cars passing through it.

Possible cause of the destruction of the Crimean bridge and the occurrence of cracks

Experts say that the Crimean bridge was built on a zone confirmed by a fault in the earth's crust. This suggests that this arrangement is unstable for the bridge. If we take this information into account, it is clear that the movements of the earth's crust in this area will affect the structure of the bridge, which is immovable. In connection with these, cracks may appear in the foundation and supports, due to constant movement.

A hall in the earth's surface is formed by tectonic plates. Earthquakes are formed from their periodic movements. Due to ignorance or simple inattention, the Crimean bridge was built precisely at their junction, which can lead to the inevitable destruction of the foundation of the bridge.

Since the Sea of ​​Azov is not very deep, it is subject to severe freezing during the winter. This suggests that the movement of ice flows can cause damage to the facade of the Crimean bridge. This damage, in the future, can lead to chips and cracks in the base. Thus, the Kerch bridge was already damaged, at one time. According to known data, it was not subject to restoration.

The Crimean bridge is “literally bursting at the seams”, it is “shaking and swaying”. Local residents are afraid that the structure will not withstand the storm and will simply collapse.

How are things at the "Putin Bridge" two months after the launch of automobile traffic on it? What poses the greatest danger to this design? What season will be the most dangerous for him? What factors, besides weather and seismology, can cause its destruction? And finally, what advice can you give to those who prefer to use this bridge?

These questions were answered by Yury Medovar, senior researcher at the Institute of Water Problems of the Russian Academy of Sciences, candidate of geological and mineralogical sciences, mining engineer-hydrogeologist, member of the RODP Yabloko party.

Obozrevatel: There is information from people who use the Crimean bridge...

Yuri Medovar: I would ask you not to call it the Crimean bridge. The Crimean bridge is located with us, in Moscow. Gorgeous, beautiful super-bridge. It connects the two banks of the Moscow River. And this is the Kerch bridge. Let's call it that.

Ok, let's. So, people say that the bridge does not withstand loads, they do not believe in the safety of this structure. They are afraid that the bridge may not withstand bad weather, strong winds and storms.

I have spoken about this many times. One of my Facebook subscribers wrote to me from Krasnodar: “The stadium was washed away in Volgograd, and the next one will be washed away by the Crimean bridge.” Everything goes to this. Nobody accepted this bridge. Nobody loaded it as it should be to load the bridge to see what the draft would be. Allegedly, Putin drove 8 KamAZ trucks. This is 150 tons of dispersed load. But not 8 KamAZ trucks were needed, but 1008 fully loaded KamAZ trucks.

Please note that this is an arched bridge. The load of the railway bridge, which has not yet been built, will be 10 thousand tons for 2 supports. And if a train of another 6 thousand tons, with vibration, goes through it? What are you! These are semi-hard clays, not granites. According to all the laws of nature, geology and SNiPs, it was impossible to build a bridge there. But this is a political decision. Nobody needs a bridge there.

So much money has been invested in its construction that they would be enough for a free transfer of passengers and cargo from Russia to Crimea for 50 years.

Is there any way to strengthen the bridge? Perhaps some action is already being taken? Do you know anything about this?

The best way is to take it apart and forget about it. How can you pin anything on a semi-hard, pardon the expression, shit? You can probably freeze it so it doesn't melt. In Russia, a similar freezing system is used under structures that stand on quicksand. But if you turn off the freezing system, such soil will thaw, it will naturally float. There were proposals to heat the supports in order to equalize the temperatures of the underwater and surface parts. In this way, internal deformation can be prevented.

- What season, in terms of climatic conditions, can be called dangerous for the Kerch Bridge?

First of all, it is autumn-winter. At this time there are colossal winds.

- What else, besides weather and seismological factors, can lead to the destruction of the bridge?

I will tell you how a small bridge collapsed in Kazakhstan during the Soviet Union. A snowplow was passing under the bridge, and at the same moment a GAZ-69 was driving along the bridge. They went into resonance, the bridge collapsed, 4 people died. The most dangerous thing is that vibrations can enter into resonance. For example, a freeze-up, which can roll up ice, or large-capacity ships, went across the sea, and cars drove from above.

Russian ships escorted Ukrainian scrap metal to prevent provocations under the Crimean bridge. The day before, two old ships of the Ukrainian Navy passed under the Crimean bridge, and Russian politicians and the military gave them accurate and capacious characteristics.

ON THIS TOPIC

True, the leader of Nezalezhnaya forgot to mention that the search and rescue vessel "Donbass" and the sea tug "Korets" are already breathing heavily. That is why they were surrounded by Russian ships.

This was necessary in order to prevent the sinking of Ukrainian ships as scrap metal, as well as to avoid provocations in Russian waters, said Mikhail Nenashev, chairman of the All-Russian Fleet Support Movement. was protected from any ill-conceived actions of Ukrainian sailors, Nenashev believes.

"We accompanied this scrap metal by planes and ships in order to respond in time to another provocation," the naval officer added.
