AbstractAs part of the modernisation of the railway line between entilj and Maribor, the existing Poehovo tunnel will be replaced by a new tunnel. The new double-track tunnel through the Pekel Mountains is around 1530 m long and will be equipped with various safety systems. DSI provided AT - Casing System 114 with squeeze connection, self-drilling Hollow Bar Anchors as well as other ground support products in one line including lattice girders, drill steel, and pumps. Breakthrough on the new Pekel railway tunnel was achieved on 18 August 2022. (photo: DSI Underground) x | |||||

AbstractTo increase overall safety, standardize Croatia's highway network, and adapt to the increased traffic to and from European countries, the Croatian Government decided to build a second tube for the Uka Tunnel - the third-longest tunnel in Croatia. DSI Underground produced and supplied anchor systems and equipment to support excavation. (photo: DSI underground) x | |||||

AbstractThe A26 Linz Motorway is one of the most important projects to improve traffic situation in Linz as well as in the surrounding area of the Upper Austrian state capital. The first section has been under construction since the beginning of 2019 and consists of an approximately 300 m long suspension bridge over the Danube, which will be anchored in the rocky slopes above the Danube, as well as the two underground motorway interchanges Danube North and South with a total tunnel system of approximately 3200 m in length with driving or main tubes and ramps.

AbstractThe excavation for the Slovenian part of the new tube for the Karavanke Tunnel started in August 2020. The geological and tectonic structure of the rock is very complex. To overcome the difficult tunnelling challenges, the contractor relied on support equipment from DSI Underground. (photo: DSI Underground) x | |||||

AbstractThe Borth underground salt mine with an annual production volume in the range of 2 m t of halite is amongst the largest underground mines in Central Europe. All mined halite is transported to the central hoisting shaft with belt conveyor systems. To ensure a safe and efficient operation of the main conveyor belt, precautionary support measures in geotechnically stressed areas of various stopes were necessary. For the rehabilitation measures, an innovative anchoring system was applied using 3.7 to 5.7 m long hollow bar anchors which were first anchored mechanically in a borehole, pre-stressed and then fully grouted with resin. x | |||||

AbstractThe joint venture Austrian Tunnel Consortium Stuttgart 21 is constructing the Filder Tunnel with a length of 9.4 km and the Ober- and Untertürkheim Tunnel with a length of 6 km as part of the Stuttgart 21 project. The tunnel Ober- and Untertürkheim as well as the middle sections of the Filder Tunnel, which are located in difficult ground conditions, were driven conventionally. The tunnelling work was carried out under the protection of the AT - Pipe Umbrella System. (photo: DSI Underground) x | |||||

AbstractThe new Nikachhu hydropower station in Bhutan has an installed capacity of 118 MW and is supplied with 25.45 m3/s via a 12,144 m long, 4 m diameter head race tunnel. Extensive tunnelling works were required for the project. In addition to a diversion tunnel, two adits were built near the dam to be able to access the desilting chambers. Five additional adits had to be built for the head race tunnel, and three adits, a ventilation tunnel, and a main access tunnel were required in the powerhouse. DSI Underground supplied Mai grout-mixing pumps and DSI Hollow Bar Spiles type R32 and T76 for this tunnel project. (photo: DSI Underground) x | |||||

AbstractRing line no.15 is one of four new metro lines of the Grand Paris Express mega-project. The construction lot T2C in the southeast of Paris with a length of approx. 7 km is a key part of the new line. It consists of a 4.7 km long tunnel between Noisy-Champs and Champigny, a 2.2 km long bypass tunnel with a maintenance station, a large-scale underground junction cavern, and intermediate access shafts. Difficult ground conditions, limited space for construction, and the requirement for minimization of settlements in an urban environment determine the ground control systems for this tunnel project. Among others, the AT - 139 pipe umbrella system with press connection and a wall thickness of 8 mm, foot piles from the DSI hollow bar system as well as GRP face anchors were used.

AbstractFrom the excavation pit of the future Sydney Metro Pitt Street station, a connecting tunnel had to be constructed underneath a busy road. To secure the station box wall, the AT - Pipe Umbrella System was used, which was installed at a 19° downwards. In close cooperation with the drilling equipment specialist Robodrill, DSI Underground has developed a successful concept for the installation of the AT - Pipe Umbrella System consisting of 60 individual pipes with a length of 18 meters each. For this project, DSI Underground's proprietary squeezed connection for pipe umbrella pipes has been used as a replacement for a conventional threaded connection. (photo: DSI Underground) x | |||||

AbstractThe Pflaurenz Tunnel, which is roughly 1 km long, is being built to provide a bypass which relieves pressure on the St. Lorenzen municipality in South Tirol. Half of the tunnel (approx. 417 m) passes through loose rock and was driven by excavators. To provide advance support, the innovative AT - Pipe Umbrella System with 139 [mm] squeezed connection developed by DSI Underground was successfully used in the loose rock sections of the Pflaurenz Tunnel to quickly and safely connect the tubes when driving the tunnel.
