The first tunnel boring machine for the construction of the Chelyabinsk Metrotram has been delivered to Chelyabinsk. According to the regional Ministry of Transport, the equipment is arriving at the "Ovchinnikova Street" construction site, where the installation of two tunnel boring shields for tunneling the "North-South" line will begin in the near future.
The complex from the Chinese company CRCC weighs 592 tons and reaches 83 meters in length. The head of the machine has already arrived in Chelyabinsk - three elements with a diameter of more than six meters, as well as technological trolleys and auxiliary equipment.
After the delivery is completed, all equipment will be lowered into the assembly chamber, where assembly will begin.
The tunneling of two tunnels with a length of 2.1 km will start from Ovchinnikova Street towards the "Revolution Square" station. As part of the first stage of the "North-South" line, it is planned to build more than 9 km of tracks, including two underground stations and three above-ground stops.
The start of tunneling work means the transition of the Metrotram project to an active construction phase.
The general contractor for the construction of the Chelyabinsk metrotram, AO "Mosproekt-3", has announced an auction for the supply of rails. The length of one steel beam should be 12.5 m.
