Manský Krolsky and tunnels
Although railway tunnels are not for a no secrets, and in the mountain, where the paved tunnel, are unlikely to build a secret bunker or a communications center (although everywhere there are exceptions), it is they look epic and even in something more interesting than Metro.
Technological photos dungeons.
Subject of underground construction has always been interesting to me, but if metrotonneli and construction I have already seen enough, the newly built railway tunnel I'm only the second time, and the very first time I saw tunneling. Diameter x \ d tunnel - 9, 5 meters instead of 5.5 metropolitenovskih, so their construction also looks bigger.
The entrance to the tunnel:
Manský railway tunnel apartment on Abakan-Taishet section of the Krasnoyarsk Railway. Inside Tunnel complex. The complex has a length of about 100 meters:
The tunnel will have a length of 2460 meters and a diameter of 9.5 meters. Apart from the main tunnel, the tunnel has already passed the technical service and the evacuation of people from the ground in case of emergency.
Laying tubing - precast elements fixing underground structures:
On an average day is built, or if it is correct to say are about 20 meters. All breed that was developed shield, sent by a conveyor belt outside the tunnel:
Excavation is made by rotating on the axis of the rotor shield steel cutters. The photo on the background of the working of the rotor. These machines work and laying the world's longest tunnel Shvetsarii:
Another worker:
Currently completed more than half of the planned length:
A good addition to the Ottoman tunnel was visiting Krolsky tunnel, which is located on the same section of the railway and which is already completed.
Krolsky tunnel until that is unique to Russia. Its uniqueness is that it was built without the use of niches in which the plan for the workers have to hide from passing trains. Instead of niches throughout the tunnel routed overhead bridge, which is much more convenient.
Portals in the old and the new tunnels Krolsky:
Old Krolsky tunnel:
Inside. The underground beauty. The tunnel under the plan soon to be reconstructed:
The portal of the old tunnel from the inside:
This new Krolsky tunnel and the one bridge on the left:
The length of the tunnel is 2253 meters. In this tunnel, even pleasant to be. We waited about a half hour before held any train to shoot him in the tunnel, but it did not work, the train does not come.
Emergency exit of the tunnel:
Go here ...
... And get into the tunnel - tunnel for technical services and evacuation of people from the ground in case of emergency:
It was a story Vadim Mahorova. A lower story of Alexander Brickman
Manske tunnel, the construction of which is JSC "Bamtonnelstroy."
The diameter of 9.5 meters, 5.5 meters against metroshnyh.
Located on the site of "Abakan-Taishet" Krasnoyarsk railroad consists of one line of a length of 2460 meters 4. Parallel builds the second string:
On the day of the visit it was passed exactly half of the way, in December 2013 - early 2014 the tunnel will be completed.
Works are carried out around the clock, rock density is f = 19, which makes it difficult tunneling. In parallel, the tunnel is a human walker, with a diameter of 3 meters in the case of an emergency evacuation.
Just one of the features is the lack of ventilation kiosks in the subway. The air is run passing train.
At the same time, we headed to the tunnel Krolsky as time was running out, and the same day had to go back to Novosibirsk.
Krolsky tunnel is the same site as the Manský.
The tunnel is unique in the sense that for all its length are service bridges for workers, instead of the usual niche, it is possible to walk freely along the wall at any time.
It consists of two long parallel lines in 2252, 1 m (I line) and in 2253, 6 m (II line). The first string Krolsky tunnel was built between the years 1961-1965, the second from 2004 - 2011.
