Tunnels near the station "Pure ponds"

Tunnels of the first stage of the Moscow Metro in difficult engineering-geological conditions of the lining constructed with reinforced concrete. The inner lining hydraulic seals supported by reinforced concrete jacket. Long-term operation of these tunnels has shown high reliability and durability of the lining, but the technology of tunnel and concrete works of the time were not allowed to develop high rates of construction of tunnels. Lining were cumbersome and time consuming.

First I went to the first path towards Lubyanka



PTO-6. I do not know how to decipher, but apparently something to do with electricity.



Women's restroom, behind it - men. Sorts in case of GO. Interestingly, they built originally, or they appear later?



Another legacy of the war. When the underground working as an air raid shelter and people hid in the tunnels (the stations were women and children), it was arranged in the distillation system of drinking water. Now on the pipe process water flows.

It turns out to be HS-158.



It seems one more toilet.



Big step on the roof of the tunnel - the following changes of the plant design. Lubyanka built in very difficult hydrogeological conditions. After construction began, it became clear that with the level of technology and experience to implement the original project did not succeed. It was necessary to abandon or station or build a different way. Timid voices of some irresponsible elements for the abolition of the station were rigidly suppressed Kaganovich.

It was decided to build in the same place, but three meters deep, which provided a powerful layer of Jurassic clays shelygoy vault. In addition, the project trehsvodchatogo palace was changed to a more modest - dvuhsvodchatuyu station. But by the time the project changes tunnels from clean ponds have already been built. It was therefore decided not to touch their vaults, and lower the tray, which led to the egg-shaped tunnel and to the steps that you see in the picture.



And this is a second way. View from the side of the Lubyanka Chistye Prudy.



Remains of some gates in front of Chistye Prudy. Just do not germovorota. Rather, it was the boom to the correct mode of ventilation when the metro functioned as a bomb shelter.



The second way stage towards the Red Gate.



HS-16X.



The station "Chistye Prudy", the first path.
