Work started on the first tube of the Rastatt Tunnel on the new/upgraded Karlsruhe–Basle rail route at the end of May 2016 as scheduled. After the so-called “flying shield start-up” for the tunnel boring machine (TBM) and penetrating the jet grouted sealing block adjoining the construction pit, the Tunnel Rastatt JV (Ed. Züblin AG and Hochtief Solutions AG) was able to commence standard operation. After 100 m had been driven, the federal highway 36 was successfully undertunnelled and then the frozen section in the Federbach low-lying area accomplished. The first 1000 m was excavated by mid-September at an average gross rate of advance of 11 m per day. This article follows up on the project report contained in tunnel 1/2016 on building the roughly 4.3 km long Rastatt rail tunnel.
The international tunnelling community will again assemble to attend the STUVA Conference from December 6 to 8, 2017. In conjunction with the Stuttgart–Ulm mega project, Stuttgart was once again...
A qualitatively high-grade tunnel lining requires the tunnel segment annular gaps to be properly grouted. At the same time, this provides a decisive contribution to a high rate of advance during mechanised excavation. The STUVA in Cologne has devised a complex and intricate unit for testing annular gap mortars in order to ensure that annular gap grouting is further optimised.

In early September 2016, one of the longest-running Robbins TBMs embarked on its most extensive project yet. The Main Beam machine with a diameter of 6.2 m, owned by the Shea-Kiewit (S-K) JV, is boring the 8.5 km long White River Tunnel as the first in the next phase of the DigIndy wastewater tunnels below Indianapolis, Indiana, USA. In addition to that work, the machine will bore the Lower Pogues Run, Fall Creek, and Pleasant Run Tunnels – a scope of work totaling about 28 km through limestone and dolomite rock.
The DB Projekt Stuttgart–Ulm GmbH began building the S-21 Tunnel “Untertürkheimer Kurve” at Untertürkheim in mid-October 2016. The first construction phase entails producing the trough for the...
The 11th InnoTrans wound up after four action-crammed days on September 23 with its best ever result. New records were recorded for exhibitor and trade visitor participation. Some 145 000 trade visitors from more than 140 countries attended this year’s leading fair for transport technology in Berlin; 2955 exhibitors from 60 countries displayed their products on the fairgrounds. The “International Tunnel Forum” of the STUVA (Research Association for Tunnels and Transportation Facilities Inc.) was again a feature over two days at this year’s fair.
