tunnelmachines projects

Ostu Stettin reports completion of 3 km x 100 sq m tunnel using Liebherr excavators for 90% of the excavation and drill/blast with Atlas Copco 145/135 drillrigs for the remainder. Concrete lining is complete and tunnel will be commissioned in mid-2000. More information visit www.geoconsult.at April 2000.

High Speed Railway
Vomp exploration drive will be utilised as the escape route from the main tunnel. A 150 m access drive has been completed towards the centre of the alignment from where contractor Jager is driving east and west in loose material. Geology is terrible in the east drive where umbrella drilling is necessary using an Atlas Copco 352 drillrig and pregrouting is being carried out to stem the water ingress. The east drive had advanced 400 m when a 50 m-high collapse occurred two weeks ago. West drive is in better conditions and has advanced 700 m to date. Steel arches, rockbolts, mesh, shotcrete, and spiling all in use for support. More from www.geoconsult.at April 2000.

Contract for 83m2 x 8.6 km two-lane second tube awarded to jv of Ostu Stettin and Hinteregger. Geology comprises limestone, dolomite and shale. Contract commenced July, 1999 on four-year schedule. August 1999.

Contracting joint venture Ostu-Stettin/Hinteregger reports completion of 60 % of the raw tunnelling on the 9.9 km-long x 90 sq m west tube of Plabutsch road tunnel. The north face has advanced 2.8 km and the south face 2.2 km, using two Atlas Copco L3C drillrigs equipped with automatic boom control.

Project on Wangchu river will generate 1020 MW and will require 22.25 km x 50 m² headrace tunnel, 2 x 992 m long pressure shafts, 2.2 km x 60 m² tailrace tunnel and underground powerhouse. Mainly Atlas Copco equipment delivered under $8 million package. Work commenced November, 1998 for completion May, 2004. Larsen & Toubro awarded RS900 million contract November, 1998 to build tunnel for Tala Hydroelectric Project Authority for completion early 2004. February 1999.

Five contract packages numbered C-1 to C-5. C-1 comprises the dam complex and 6 km of headrace tunnel (HRT) awarded to Hindustan Construction Company (HCC); C-2 excavation of HRT from 6 km mark to 11 km mark awarded to Jaiprakash Industries; C-3 excavation of HRT from 11 km mark to 15 km mark awarded to Larsen & Toubro; C-4 excavation of HRT from 15 km mark to 22.9 km mark awarded to HCC; C-5 comprises surge shaft, pressure shafts, powerhouse, and 2.2 km tailrace tunnel awarded to Jaiprakash. Each of the contracts has its own access roads and adits, and the individual sites are self-sufficient. Client THPA has built 80 km of access roads to date and work is proceeding on another 20 km to complete. THPA also procured a starter pack of equipment for each contract during tender phase in order to speed up mobilisation. These were on a cost reimbursement basis and included per contract: an Atlas Copco 352 drillrig; a Boltec 435 H rockbolter; a CIFA CSS 2 Spritzsystem shotcrete jumbo; a CK90E 1.2 cu m electric loader; and two Wagner MT 420 dumptrucks. Contractors have since been adding to the fleet, generally purchasing more of the same models.

To date, HCC has completed the diversion tunnel under C-1 and is proceeding to establish three massive desilting chambers and the first section of HRT. Jaiprakash has not been so fortunate on C-2 where it had to deal with a 15 m-long face collapse when it intersected an aquifer 122 m from the portal in its Pade Chu adit. Currently advancing with caution under the protection of 15 m probeholes. Larsen & Toubro has more than half completed its 975 m-long Gedu Chu access adit under C-3, and HCC has nearly completed its 301 m-long Mirchan Chu access adit on C-4. Jaiprakash is portalling at the surge shaft position on C-5. More information from mdthpa@druknet.net.bt October 1999.
