Project of the year incl.renovation up to €50M: Modernization of the Vladivostok tunnel of the far eastern railway, Russia

23 November 2019

For the first time in Russia, Mosmetrostroy developed a project and applied the technology of modernization of a railway tunnel, built 82 years ago, where one facility was adapted to specific working conditions and applied various modern world achievements and innovations in the field of transport infrastructure facilities. The applied technical solutions made it possible to obtain a fundamentally new multi-layer lining of the tunnel with high technical and operational characteristics, in which all layers are included in the construction. The task was successfully implemented with a significant reduction in terms (by 1.5 years) and the cost of work (2 times) relative to the initial project, according to which it was planned to carry out reconstruction of the tunnel with a complete tunnel closure for train traffic for the period of work with the construction of the bypass railway section through the city center. With the use of modern technologies during tunnel modernization, a significant social effect was achieved: uninterrupted delivery of goods by rail to the seaport of Vladivostok and from the port, to a heat power-station, as well as for urban needs for the entire duration of work at the facility. The implementation of this project by Mosmetrostroy allowed to increase the throughput capacity of the modernized railway section and reduce operating costs, improve the environmental situation in the tunnel zone due to the organized drainage system.
 

The positive results achieved make it possible to further disseminate this technology when modernizing numerous other tunnels located on a huge railway network in Russia and abroad, many of which are of considerable age from the moment of construction and also require modernization to meet modern requirements and operating conditions.
