Cable civil engineering Untertürkheim

Digital technology step by step

Cable civil engineering, draw-in of cables, foundation and production of track field concentrators, new construction, conversion, and dismantling of signal brackets

In connection with the project Digitaler Knoten Stuttgart, we were awarded the contract for creating the basis required for controlling the railway junction Stuttgart by means of digital control centres. Foundation of four track field concentrators and their surroundings, installation of approx. 16,000 m concrete cable duct, as well as approx. 70 pcs. track crossings. New construction of a total of four signal brackets, as well as the conversion and dismantling of one signal bracket respectively. Laying of a total of approx. 400,000 m cables. Foundation of 190 signals on nine different railway lines.

Electronic control centre Osterburken

Railway infrastructure in Baden-Württemberg is being updated

During the complete shutdown from the end of July until the beginning of September about 6,500 m of new cable ducts of the sizes I to IIIa were installed for the new electronic control centre in Osterburken. For the production of cable conduit routes, a boundary path of 1,200 m had to be built in certain areas of railway embankments before the cable ducts could be installed. This boundary path is composed of ballast supporting slabs, which are stabilised by driven-in HEA steel beams. Along the two lines 4120 and 4900, 73 signal foundations were built for the new control, communication, and safety systems by means of driven casing pipes TECDOWN or by means of the monolithic construction method. In order to guarantee the new cable route, 43 track crossings in open construction method were built along the entire line. For building them the track system was opened and the empty conduits installed and concreted under the rails. At three neuralgic points concerning the sighting distance of the signals it was necessary to produce three new signal brackets. For the foundation of two signal brackets, two steel pipes with a diameter of 700 mm were driven in and a ridgepole with foundation basket was concreted. For the third signal bracket a complete sheet pile wall casing was driven in up until reaching a load-bearing soil layer and anchored to the ground by means of additional micro piles. In order to enable the technical equipment to communicate with each other, approximately 120,000 m cables were laid for the entire project.

TANV Ansbach - Crailsheim

Renovation of the fibre optic cable connection between the station Ansbach (Bavaria) and the station Crailsheim (Baden-Württemberg) on a stretch of 49 km. Production of a new cable duct system with 13 km support construction during a challenging shutdown concept with continuous nightly shutdowns (37 consecutive weekends). 51 km laying of new fibre optic cable.

Cable route Hechingen-Sigmaringen

Modernisation of the stretch in the region Zollernalbkreis

Underground engineering for the production of a cable route. The following performances were carried out: new construction of cable routes, 9.7 km of which in glass fibre reinforced cable duct on supports and 3.1 km in concrete cable duct, as well as 35 km further existing cable routes. New construction of 52 cable chutes, 12 track crossings and 15 road and path crossings. During these works 55 km cables were laid.
