\u017dSR Railway track P\u00fachov – \u017dilina, Tunnel Diel<\/h2>\n

Modernization of railway track P\u00fachov – \u017dilina for speeds up to 160 km\/h, 1st stage – Diel Tunnel<\/h4>\n

Investor:\u00a0<\/strong>Railways of the Slovak republic, Bratislava (\u017dSR)<\/p>\n

Site location:\u00a0<\/strong>Nimnica<\/p>\n

Upper Contractor (Client):\u00a0<\/strong>TSS GRADE, a.s.<\/p>\n

Building Description:<\/strong>
\nPart of the tunnel is proposed for modernizing railway track P\u00fachov – Pova\u017esk\u00e1 Bystrica track section P\u00fachov – Pova\u017esk\u00e1 Bystrica stationing of (axis of the track # 1) NZKM 161.422 973 162.506 000 NZKM to the overall length of 1081.7 meters. Passes through the peak of the top part that forms the central bend of the scale of the section of the flow.<\/p>\n

Tunnel tube is divided into sections constructed by punching and cupping. Excavated sections are built in open construction pit at both portals that are subsequently backfilled and rehabilitated so that the character of the natural environment has been preserved.
\nMined part of the tunnel will be implemented according to the principles of NATM using mechanical disintegration in the portal areas. Explosive rock breaking process will be used for tunneling work in the tunnel tube more compact parts of the rock mass.
\nThe tunnel lining is designed double-up by the primary and secondary lining.
\nBased on the requirements of Regulation TSI-INS TSI-SRT (2008 \/ EC) will Diel tunnel equipped with emergency gallery dl. About 304.15 meters and cross-linking the tunnel tube l. About 21m. Profile cross-linking is identical to the profile of the escape tunnel. The horizontal alignment of the table is designed as a polygon in parallel with the axis of the tunnel tube. Tunnel is terminated at the eastern portal of the tunnel works.<\/p>\n

Basic parameters of the tunnel:<\/strong>
\nType of tunnel: The single double tracked
\nTunnel length in the axis of the tunnel: 1081.7 m
\nLength excavated part: 1050.0 m
\nBetween the tracks: 4.2 m
\nStructure gauge “C” with adapter for electrified lines
\nLine speed: 160 km\/h (prospective speed of 200 km\/h For drive units with tilting bodies
\nLeakage path: on both sides of the tunnel
\nHeadroom above the walkway: 2.25 m
\nThe length of the escape tunnel axis: 304.150 meters
\nLength of escape tunnels, including jumpers: 325.15 m<\/p>\n
