The portal sliding gate will protect the tunnel from environmental hazards, increased humidity and low temperatures. One of the main tasks solved by the specialists of ORPE Technologiya was to provide the predetermined stiffness of a gate leaf. On the other hand, in an emergency - break-down of automatic equipment or a drive mechanism, it must be destroyed by a railway engine without damaging a railway train.
Gate leaves are sandwich panels 6.8 meters high and 3.2 meters wide consisting of fiberglass skins and core material. The weight of each leaf is 850 kg. In April 2019, the enterprise will produce the first set of gate leaves, which includes two large-sized products, and hand it over to the customer, Obukhov State Plant. Two other sets will be delivered in May and June this year.
“Our enterprise has an extensive experience in implementing such projects. In 1998, we produced similar structures for the Severomuysky Tunnel of the Baikal-Amur Mainline. The tunnel portal sliding gate produced by the specialists of ORPE Technologiya is still protecting this structure from environmental hazards”, said Andrei Silkin, Director General of ORPE Technologiya.
The Baikal tunnel is a railway tunnel at the Baikal-Amur Mainline on the section Kunerma-Severobaikalsk. It is located at the boundary of the Irkutsk Region and Buryatia and passes through the Baikal Mountains. The length of the tunnel is 6685.6 meters. It is planned to put the tunnel into operation in 2020. The opening of the new Baikal tunnel is expected to double the carrying capacity of the section Severobaikalsk-Lena and to develop promising rail traffic on the Northern route of the East Siberian railway.
