Map with all coordinates: The Sohlberg Tunnel is a 1,729 m long railway tunnel on the high-speed line from Hanover to Würzburg ( route kilometers 66.6 to km 68.4). It crosses the 280 m high Sohlberg in the area of the Ahlshausen district of the Lower Saxon town of Einbeck .
course
The south portal is at 68.376 kilometers.
The route runs in the tunnel to the south largely in a left curve. The gradient rises continuously towards the south, but flattens out continuously from the north portal (8.199 per mille slope) to the south portal (3.350 per mille). The maximum overburden is 75 m.
Layers of the Middle Buntsandstein are traversed along the entire length . From north to south, the consequences are Sölling (sm5), Hardegsen (smH), Derfurth (smD) and Volpriehausen (smV).
To the north of the tunnel is a 60 m long and up to 5 m high dam, which merges into a one kilometer long incision up to 125 m wide and 20 m deep. This is followed by the 1,056 m long Auetal bridge .
To the south there is a short incision, which merges into a 50 m long dam at 68.422 km. This is followed by a bridge over the Wambachtal (km 68.470 to km 68.532). Another 50 m long dam is followed by an 880 m long and an average of 14 m deep cut at 68.580 km. The Krieberg tunnel joins at km 69.464 .
history
planning
The tunnel largely belonged to planning approval section 2.14 of the new line. The northern section (building kilometers 67.450 northwards), on the other hand, was in section 2.13.
In 1982 the planned length of the structure was 1729 m.
As part of the geological exploration, test bores were drilled at a distance of 100 m.
construction
Anni Schreiber, wife of the local mayor in the neighboring village of Opperhausen, acted as tunnel sponsor. It triggered the first demolition at the start of construction.
The tunnel was completely excavated from north to south using the mining method. The tunneling work began in May 1984 (other sources: April 1984) and ended in May 1985. The construction cost was 35 million Deutschmarks.
In December 1984, 580 m had been driven.
A total of 210,000 m³ of material was excavated, and a further 49,000 m³ of material was incurred when excavating the pre-cuts . A total of 42,000 m³ of concrete and 2,000 t of steel were used. The outer shell was made 35 cm thick.
According to other information, 780,000 cubic meters of material from the Sohlberg tunnel were stored in an 11.8 hectare landfill near Opperhausen . This previously agriculturally used area has been afforested . The location was chosen in agreement with nature conservation authorities and farmers.
The construction work ended in 1986. The company Ed. Züblin (Hanover), A. Kunz GmbH (Essen), F. u. N. Kronibus GmbH & Co KG (Kassel) and Walter-Thosti-Boswau AG (Hanover). The tunnel was built by miners from southern Germany, Austria and Yugoslavia.
