Map with all coordinates: The Günterscheid tunnel (also tunnel Günterscheid ) is a 1130 m long railway - tunnel of the high-speed line Köln-Rhein / Main . It crosses under two ridges of the Auf der Silberkaul ridge north of the Günterscheid part of the local community of Windhagen and therefore bears his name. The western and northern sections of the tunnel are located in the area of the local community Windhagen, the eastern and southern sections in the area of the local community Neustadt (Wied) .
course
The north portal is at 48.6 km and the south portal at 49.7. An emergency exit leads in the middle of the tube, at 50 ° 37 ′ 46 ″ N , 7 ° 22 ′ 33 ″ E , to the edge of a wooded area.
The tube runs straight and rises continuously to the north. The overburden is up to 30 m (other source: 24 m). To the north of the tunnel is the Fischerhaus valley bridge , to the south the Hallerbachtal bridge .
The tunnel is the northernmost of the three Rhineland-Palatinate tunnels in Lot A of the new line. Between the tunnel meters 210 and 450, the tube, as well as the passes under Ittenbach tunnel , between Frankfurt and Cologne current natural gas , and - ethylene - pipelines .
history
planning
At the end of 1995 and 1998 the planned length of the tunnel was 1095 m. In mid-1999, however, the structure was planned with the length of 1130 m, which was realized later.
construction
The tube was built using mining techniques over a length of 1060 m. Only the portal areas were built using the open construction method . Due to difficult ground conditions a propulsion was only partially offset by excavators done. Blasting was necessary on longer stretches, particularly when the butt and sole erupted . In the area of the southern stop, a ridge tunnel had to be driven over a length of around 40 meters. Due to the loose rock, a spike protection was mostly necessary.
In the area of the pipelines, which run more than 20 meters below the tunnel floor, favorable, homogeneous rock conditions were encountered. Additional lifting of the pipelines was therefore not necessary. Construction began in autumn 1998 and the shell was completed in early 2001.
A total of 159,000 m³ was excavated, 19,400 m³ of shotcrete and 23,400 m³ of structural concrete were used.
Rescue drill in April 2008
On the night of April 5, 2008, between 12:35 am and 4:30 am, a large-scale rescue exercise took place in the tunnel. Around 320 passengers, including 30 with simulated injuries, were evacuated as part of the exercise. While the ambulatory passengers could be brought to safety within eleven minutes, the 30 "injured" were evacuated by rescue workers. 450 rescue workers were involved in the exercise. Exercises like this take place every three years on the new line.
