The installation of the smoke removal system at the Tyutchevskaya station under construction of the Troitskaya metro line is 50% complete, according to Mr. Andrey Bochkarev, Deputy Mayor of Moscow for Urban Planning and Construction.
The Mosinzhproekt Group of Companies is a general designer and general contractor for the construction of new lines and stations of the Moscow Metro.
“22 smoke intakes have been installed in the ceiling on the platform section, which will draw smoke out from the station through a ventilation duct in case of emergency”, stated Mr. Andrey Bochkarev.
According to Deputy Mayor, the smoke and general ventilation systems are being installed at the Tyutchevskaya station.
“Whenever the fire alarm triggers, the sensors and all the fire extinguishing and smoke removal systems are automatically activated”, specified Mr. Andrey Bochkarev.
Mr. Yuri Kravtsov, CEO, Mosinzhproekt JSC, added that more than 300 sprinklers would be installed on the ceiling in the headshunt zone.
“In emergency situations, the sprinklers will spray water at high pressure, which will form a mist that works efficiently against fire”, informed the head of the engineering holding.
He said that the installation of air-conditioning and sanitary drainage systems was underway.
The 40 km long Troitskaya Line under construction will connect the platforms of the Moscow Central Circle (MCC) with the urban district of Troitsk, passing through Southern, South-Western, Troitsky and Novomoskovsky districts of the capital. The expected daily passenger traffic flow is about 100 thousand people per day. Around 1 million people live in the attraction zone of the new stations, and several hundred thousand more work or study nearby.
