  The 2.56 km-long fourth Elbe tunnel broke through safely on 1st March, 2000 after a harrowing 29 month drive. The 14.2 m-diameter Herrenknecht Mixshield, the largest ever built, worked at up to 14 m/day through extremely complex ground comprising gravel, granite blocks, sand, silt, tillite and mica silt under pressures of 5 bar with minimum cover of 7 m to the riverbed. A stonecrusher positioned behind the cutting wheel dealt with boulders up to 1.2 m-diameter, while an integrated active centre cutter with a diameter of 3 m located in the middle of the cutting wheel was able to drill independently up to 0.6 m ahead to prevent adhesion. Acoustic reflection measurements detected geological changes up to 40 m ahead of the machine. The 2,600 t, 3,200 kW machine will now be refurbished for a 3.2 km-long city motorway tunnel in Moscow.

  Weser, near Bremen, twin highway tunnel 2 x 1.6 km using 11.67 m-diameter Herrenknecht Mixshield S-152. Contractors Hochtief AG, Philipp Holzmann AG, Ludwig Freytag GmbH, Heinrich Hecker GmbH and Martin Oetken GmbH. November 1999.   11.7 m-diameter Herrenknecht Mixshield has completed 1.3 km with 300 m to go on south tube. Will be dismantled and taken back across Weser for relaunch for north tube after planned modification to cutterhead to improve bentonite flow through integral rock crusher. Ground conditions are sand, clay, gravel and boulders up to 1 m diameter. 140,000 t of Norwegian granite of 150 mm nominal sizing placed as carpet over 500 m-long x 75 m-wide section of riverbed as protection against blowout and tunnel elevation has been deepened by 3.5 m. The 30% of cutters visible above the lowered bentonite level have been changed twice by divers, but slower progress is presently more acceptable than further cutter changes at up to 4.5 bar. Segmental lining outside diameter 11.3 m and 50 cm thick with 1.5 m width. Weight of 6+1 ring is 65 t. Average advance 3 rings/day in clay and 10 rings/day in sand.

  A JV of Hyderabad-based SEW Constructions, Prasad Constructions Works and Iranian contractor Sabir successfully bidded for the 18.8 km Veligonda tunnel project, located on the right bank of Srisailam Reservoir. The client is the Department of Irrigation of the Government of Andhra Pradesh.As the finished diameter is 7 m and an old double shield hard rock TBM of 7.9 to 8 m in diameter is not available, a new double shield hard rock TBM is the preferred method. The TBM is planned to commence from the exit portal. The contractor is currently in talks with the TBM manufacturers. Muck removal is planned by continuous conveyor belt. The selection of suppliers is also under negotiation. Interested firms are invited to submit their quotations.The Veligonda project envisages withdrawal of water through the Veligonda straight tunnel, with a carrying capacity of 85 cu m per second, into a new reservoir which is being formed by plugging three gaps. Works are in progress downstream of the tunnel, including the open channel / canal and the dams to shape the reservoir, which makes the completion of the tunnel a critical component for the successful completion of the project and utilisation of the water. The water tightness specifications have not been mentioned by the owner / client and no water loss measurements would be undertaken at the inlet and exit. The geological strata is dominated by quartzites varying from 180 MPa to 230 MPa, shales and phyllites of varying strengths from 80 MPa to 140 MPa. No shaft, adits or caverns are necessary. At the exit end the tunnel, the bed is only 26 m under the current ground level. The planned date to start tunnelling is January 2007. Construction time: 36 months. Construction cost: USD142 million. Given the above criteria and lack of stiff prerequisites from the client, the JV is opting for honey comb precast lining or bolted segments with a simple economical design. The number of segments per ring depends on the design. The JV wishes to commission the lining design to experienced firms who can save on the construction costs thanks to efficient design.

The scheme will transfer water from the Krishna river to the Pakasam, Nellore and Cuddapah districts of the state. The contract also includes operation and maintenance of the tunnel for a period of two years after successful commissioning of the tunnel. The company's 60% share of order is INR4.41 billion. The project is to be completed in 60 calendar months. Visit www.hccindia.com 21/07.For the Veligonda I project, one Herrenknecht hard rock double shield machine will be used. The diameter of the cutter head is 7,960 mm, the cutter head power is 2,800 kW (8 x 350 kW), the total thrust is 14,418 kN and the cutter head torque is 8,470 kNm. The tunnel is followed by an open channel which would carry water to the downstream reservoir. The access to the tunnel is from the open channel. The TBM assembly area has been prepared at the transit point where the tunnel discharges water into the canal/open channel. The first batch of the machine part has arrived at the Port in Chennai and is awaiting customs clearance. The boring is expected to start from August onwards. Honey comb concrete segments will be installed, with four segments per ring. The segments will be produced nearby the project site by the JV of contractors, SEW Construction, Prasad Constructions Works and Sabir. The supplier of the segment plant and moulds is Herrenknecht. A conveyor belt, which is being designed by in-house and local experts, will be used for rock evacuation. The Veligonda project has two tunnels of 7 m and 9.2 m inner diameter. The second, 9.2 m ID tunnel parallel to the 7 m ID tunnel has been awarded recently to Hindustan Construction and Coastal Projects. Click in/42. Visit www.herrenknecht.com 23-24/07.

  First phase of proposed 55.3 km 3-line network involves 11 km of underground railway between Delhi University and the Central Secretariat near Parliament House using TBMs. Completion 2007. General consultants: joint venture led by Pacific Consultants International (Japan) and including Jarts and Rites. Client: Delhi Metro Rail Corporation. September 1998.   Fifteen consortia, each associated with one or more local companies, have been shortlisted for construction of the 11 km-long underground section. The rest of the network will consist of 44.3 km of elevated and surface lines from Shadara to Nangloi and Subzimandi to Holambikalan. The US$690 million underground contract will be let as two separate packages: design and construction of the 4 km-long section from Delhi University station to the south end of the Inter-State Bus Terminal (ISBT); and design and construction of the 7 km-long section from ISBT to Central Secretariat. Among the shortlisted bidders for one or both packages are: Impregilo (Italy), Nesco (Spain), with Gammon (India); Kumagai Gumi (Japan), Skanska (Sweden), with Hindustan Construction (India) and Itochu (Japan); Dyckerhoff & Widmann (Germany), Shimizu (Japan), and Larsen & Toubro (India); Samsung (South Korea), with Ircon International (India); and Hyundai (South Korea), with Jai Prakash (India). Total cost of the metro project is now expected to be more than US$1.8 billion on completion. January 2000. Line 1 will run 11 km underground from Delhi University at Vishwavidyalaya in the north to Central Secretariat in the south, serving 10 stations. Line 2, the first 25 km surface/elevated route, will link Shahdara in the east to Nangloi in the west via Subzimandi and Tri Nagar. Line 3 was intended to run 19.3 km from Subzimandi to Holambi Kalan, but as this parallels an existing Indian Railways (IR) line, the government is considering whether to build a 16-km route from Tri Nagar to Barwala instead. Tenders are currently being evaluated for construction of Line 1 (underground), and the winning contractors should be announced later this year. Firms shortlisted for the project include Kumagai Gumi, Kajima Corp. and Obayashi of Japan, Skanska AB of Sweden, and Dywidag of Germany. With a water table only 1.5 m below ground level, underground construction will be challenging. From Vishwavidyalaya to New Delhi the ground is a mix of soft soil and quartzitic rock varying from sound to highly weathered. Between New Delhi and Central Secretariat the soft soil is mixed with silt, clay and sand. Construction will be split into two sections, north and south of ISBT. Nine of the stations will be built by cut-and-cover, except Chwari Bazar, which will be NATM. The running tunnels will be bored by EPBs. The northern half of the route, from Vishwavidyalaya to ISBT, is due to open in March, 2004 and the southern section in March, 2005. To help with project management, DMRC has brought in a number of general consultants, including PCI, Tonichi and JARTS of Japan, Parsons Brinckerhoff International of the USA, and RITES (Rail India Technical & Economic Services) of India.
