Severomuyskiy Railway Tunnel

Buryatiya, Russia

Category: Transport, Tunnel

Description

Originally built in the 1980s and stretching for 15.3 km (9.5 miles) along the Baikal-Amur Mainline Railway, the Severomuyskiy Tunnel is the longest railway tunnel in Russia. The almost 26-year construction period faced extreme challenges, including difficult rock formations, four major faults, substantial underground water - sometimes with exceptionally high hydrostatic (3.5 MPa) pressure, and an underground lake that delayed progress for 18 months. The layout of the new tunnel has reduced the original steep slopes of the tunnel by 6-7%, enabling more freight to be successfully transported through this line.

Products Used:

The complete range of PENETRON topical crystalline material, PENECRETE MORTAR and PENEPLUG, a fast-acting cementitious sealer, were used to ensure a durable and impermeable concrete structure.
