The north portal

The Aegidienberg tunnel is a 1240 m long railway tunnel on the high-speed line Cologne – Rhine / Main . It passes under the Aegidienberg district of Bad Honnef .

The tube accommodates two tracks on slab tracks , which can be driven on as planned at 300 km / h.

Location and course

The north portal is at km 41.3 and the south portal is at km 42.5. An emergency exit leads to the surface around 250 m north of the south portal, on the edge of a residential area in the Hövel district (south of Kochbacher Strasse ), at 50 ° 40 ′ 8.4 ″  N , 7 ° 18 ′ 15.4 ″  E.

Along with the Ittenbach Tunnel and the Rottbitzetunnel , the tunnel is one of three tunnels in which the route passes through the Siebengebirge over a length of around 14 km.

The gradient of the route rises continuously in the tunnel in a southerly direction.

The emergency exit of the tunnel

South of the tube is the 200 m long Kluse tunnel, one of the shortest tubes on the route. The Logebach valley bridge follows about 100 m north of the north portal .

history

planning

The planning status from the beginning of 1992 already provided for a tunnel in the Aegidienberg area. The planning status from the end of 1995 envisaged a length of 1,240 m. The structure was later realized with this length.

The structure was in planning section 3 of the new line in North Rhine-Westphalia.

construction

After the preliminary paleontological exploration in 1994 came across fossil plant remains, the section between kilometers 40.380 and 41.800 was classified as a palaeontologically relevant area. The early construction phase of the Aegidienberg tunnel and the neighboring Logebachtal bridge was marked by numerous archaeological and geological finds. Between November 1998 and March 2000, almost the entire 1.3 km section was examined almost completely. In November 1998, the ongoing preparatory work for the tunnel was temporarily interrupted after 400 million year old fossils had been found. In total, scientists found more than 10,000 fossils.

The tunnel was officially on 16 June 1999 struck . Bärbel Höhn , the then Environment Minister of North Rhine-Westphalia , acted as tunnel sponsor . With the push of a button, it triggered an explosion. More than a thousand citizens accepted the invitation to an "Open Tunnel Day" that same afternoon.

With an overburden of up to 30 m, the tunnel was driven largely using the mining method . In the north, a 55 m long incision was made beforehand , in the south an 80 m long area was later built using an open cut. This 80 m long trough in front of the tunnel is intended to prevent the groundwater level from falling permanently .

In the field of built by mining tunnel traverses thereby the approximately ten meters under its sole lying Erbstollen Arnold , an approximately 1.5 m wide and 2.5 m high cleat from previous mining activity in the region. Before the inner shell of the new tunnel was constructed, the hereditary tunnel was filled in to ensure the tunnel's stability. Before construction began, the position of the tunnel was determined by means of holes 150 mm in diameter.

Various species of fish were found in the excavated material from the tunnel, which is around 400 million years old, including around 200 parts of a rhinoptera , an armored giant fish. The tunnel area was located in the Devonian , around 330 million years ago, in a shallow estuary that stretched between Aachen and the Alps.

The breakthrough took place on October 20, 1999. It was the first breakthrough of the three tubes in the Siebengebirge.

A total of 23,500 cubic meters were broken m³ 165,800, spraying and 26,500 m³ of structural concrete expended.

Installation

On February 16, 2002, a large-scale exercise with 168 helpers took place at the tunnel.

The symbolic opening of the high-speed line and thus also of the Aegidienberg tunnel took place on July 25, 2002; passenger service started on August 1st.
