Reference project track-foundation-laying train: Foundation for a signal bracket in Hamburg

A pile was driven in as the foundation for a signal bracket during the construction of the new S4 S-Bahn (suburban) railway link (Hamburg – Bad Oldesloe). The foundation was located on an embankment between the tracks of the S1 S-Bahn rail link and the mainline railway – it was therefore not possible to access it from the outside – but that was a situation for which the track-foundation-laying train was literally designed for.

The track-foundation-laying train allowed the workers to complete the foundation for a signal bracket in an inaccessible location within less than 40 hours – and without the need to dismantle any railway infrastructure. A total success!

Foundation in just 40 hours - the work flow:

2.00 a.m.: The shoring work began at the foundation point once the construction track had been installed. The track-foundation-laying train was prepared at a nearby suburban railway siding at the same time. The foundation pipe (DN 813) was attached to the hydraulic vibrator and vibrated 6.5 metres into the ground along with the welded-on side plates once the track-foundation-laying train had been positioned at the foundation point. The track-foundation-laying train was then converted on site to the Kelly drilling method for the purposes of boring out the foundation pipe down to the base.

The foundation pile was concreted with the reinforcement cage having been lifted into place that same evening.

The reinforcement work for the head foundation with the integrated anchor rods as a connection for the signal bracket to be fitted later was commenced the next morning.

The prefabricated concrete element was placed over the lost formwork, the anchor rods were aligned for the final time and the head foundation was concreted at around midday.

Heavy duty machinery and Foundation Construction Train: News

On behalf of our client Königbau, HERING Grundbau GmbH was deployed in Offenburg: At a total of three foundation locations, six driven piles were installed with precision to a depth of around ten metres using our Foundation Construction Train and the MR-105 V vibratory hammer.

Foundation Construction Train of HERING Grundbau GmbH

This work provides the reliable foundation for future signal gantries and makes an important contribution to a stable rail infrastructure.

A particular highlight of the project was the joint barbecue evening held directly on the construction site. Together with our client and the on-site team, the successful operation was celebrated in a relaxed atmosphere.

Moments like these demonstrate what successful collaboration is all about: trust, team spirit, and true partnership!
