Mined Construction for intersecting Structure for Main-Line and Light Rail Access in Bad Cannstatt

The DB Projekt Stuttgart-Ulm GmbH started work in mid-February 2017 at the Rosensteinpark in Stuttgart in the vicinity of the Ehmannstraße employing mining means to produce the intersecting structure for the Bad Cannstatt mainline access and light rail feed. The DB was obliged to switch from the cut-and-cover construction method originally included in the planning process at the Ehmannstraße, after wildlife conservation experts discovered two host trees used by the strictly protected hermit beetle and four other trees possibly containing the insects.

Västlänken: Planned Railway Tunnel under the Centre of Gothenburg

Västlänken – the West Link – is a planned railway tunnel under the centre of Gothenburg. As from 2026 three new underground stations are scheduled to provide increased capacity for commuter rail services and improve accessibility to the city. As commuting times are reduced, the labour market is expected to expand and promote regional growth and sustainable development. Several of the areas passed through by the West Link pose major geotechnical, hydrogeological and technical challenges concerning the protection of the environment and existing buildings.

Special Foundation Works for the Schwarzkopftunnel Bypass

Between Würzburg and Frankfurt, the German railway company Deutsche Bahn has a route section newly built which is to replace passage through the Schwarzkopf Tunnel. The almost 160-year old tunnel no longer meets today’s requirements; passenger trains can only pass through the tunnel with reduced maximum speed. Heavy freight trains however need additional helper engines due to the steep inclination. Bauer Spezialtiefbau GmbH executed in a joint venture all required special foundation works which could not be constructed by mining method.

Thames Tideway Tunnel: Upgrade for London’s Wastewater System

London’s water and wastewater system provider, Thames Water, is improving its water quality through a three-stage upgrade. After redeveloping its clarification plants and opening the Lee Tunnel, a combined facility for storage and the conveyance of sewage mixed with rainwater in the east of the city, now the Thames Tideway Tunnel is being tackled. It is the biggest project, entailing investments of ca. 4.2 billion pounds sterling. As from 2023, it is intended to carry sewage from 34 of London’s largest combined sewer overflows over a length of 25 km, store and transfer it to Lee Tunnel. The article in tunnel 8/2016 describes the main construction measures and special features of the Thames Tideway Tunnel, particularly the West Section.

Tunnelling the Gotthard – Success Story GBT

The design and construction history of the Gotthard Base Tunnel has set standards for modern tunnel building. Tunnelling projects all over the world will profit from the innovations in tunnelling technology, concrete and waterproofing systems and materials management. In order to ensure this knowledge and practical experience for posterity, the Swiss Tunnelling Society (STS) has now published the reference book “Tunnelling the Gotthard”, a documentation of the project that is unique in this form. After the publication of the German edition for the opening ceremonies in June 2016, the English edition of this project documentation is now available in time for the official start of services in the GBT.
