The Combined (motor and rail) road Adler – mountain resort «Alpika-Service»
Contractor: JSC Lenmetrogiprotrans
Location: The Federal highway Adler — Alpika - Service, Adler district, Sochi, Krasnodar Krai
Commissioned: 2013
The construction of railway and road tunnel complex № 1:
Length of road tunnel 2296 m, two lanes, the cross section of the tunnel 131,55 m2, the length of railway tunnel 2523,5 m, single-track section 75,95 m2. The superstructure - continuous way, ballast. The primary lining of the tunnels horseshoe shape made of reinforced concrete.
Seismic intensity for average soil conditions - 9 points. Within the site developed a complex physical-geological phenomena: landslides, avalanches, karst, the processes associated with exposure to groundwater.
The construction of railway and road tunnel complex № 3:
Length of road tunnel is 3200 m, the cross section of 138 m2, two lanes, the length of railway tunnel 4631 m, cross section in tunnelling 81.71 m2, single-track tunnel. The project road tunnel, exploration and escape galleries, a railway tunnel. The project includes excavation of the tunnel boring mechanized complexes in the 9.7 m diameter railway tunnel, and 12.7 m for the road tunnel. The tunnels provided a weldless design of the permanent way on concrete small-sized frames with a width of 1520 mm. the length of the frame along the tunnel of 1.99 m, width 2,45 m.
Seismic intensity for average soil conditions - 9 points. The presence of adverse factors: available only to registered and landslide processes, erosion, surface washouts, ravines, and sat down.
The construction of railway and road tunnel complex № 5:
Length of road tunnel 1372,2 m, cross section 118,5 m2, two lanes, the length of railway tunnel 2910,2 m, cross section in the sinking of 89.75 m2, single-track tunnel. The tunnel is made of high-precision waterproof tunnel lining with precast concrete blocks with a cross section of circular shape outer diameter of 10.3 m. the superstructure - continuous way on the concrete ties on the gravel bottom (ballast)/
Seismic intensity for average soil conditions - 9 points. The area of the projected tunnel is characterized by a high degree of hazard of exogenic geological processes: landslides, weathering, karst, rockfalls, landslides, avalanches, processes associated with exposure to groundwater. The route runs along the Mzymta river. The tunnel complex includes: railway tunnel, road tunnel, service tunnel, escape tunnels, escape galleries, buildings.
The construction of railway tunnel № 2, railway tunnel № 4, railway tunnel № 6:
Single-track railway tunnels, Length of tunnel № 2 - 166,86 m length of tunnel № 4 - 449,3 m, the length of tunnel № 6 - 433 m. The superstructure is continuous path on reinforced concrete sleepers on the gravel bottom (ballast). The main lining of tunnels made of reinforced concrete.
Seismic intensity for average soil conditions - 9 points. The presence of adverse factors: available only to registered and landslide processes, erosion, surface washouts, ravines, and sat down.
