Map with all coordinates: The Erbelberg tunnel is a 228 m long railway tunnel on the high-speed line from Hanover to Würzburg . The tunnel crosses under the Erbelberg forest area and therefore bears his name.
Location and course
The structure is 16 km south of Kassel , between the Mülmisch and Breitenbachtal bridges .
The cover is 10 to 15 m. The cross-section is designed as a vault with a continuous base vault.
history
In the area of today's tunnel, the preliminary design plan initially included an incision with bridges for crossing paths and roads. In the planning approval procedure , for agricultural and forestry reasons, preference was given to a tunnel solution in order to avoid the space required for an incision about 150 m wide due to a necessary slope of 2: 1. Last but not least, this took account of the demands of the forestry industry to preserve the forest in the area of the tunnel and to enable subsequent reforestation.
In the planning and construction phase, the structure was part of planning section 13 of the new line. In 1984 the tunnel was planned with a length of 200 m. The calculated costs were 7.0 million DM.
The structure was erected using the open construction method in a 1: 2 excavation pit slope.
