Ib tug tshwj xeeb qauv nyob rau hauv cov kev txwv ntawm lub tsev project yog lub Göggelsbuch qhov nrog ib tug tag nrho ntev ntawm 2,287 m. Qhov tunnel no muaj tag nrho cov hla ntu ntawm kwv yees li
150 m2 thiab suav nrog ib qho kev cawm siav nrog ob qhov kev tawm thaum muaj xwm txheej ceev nyob rau hauv nruab nrab ntawm lub qhov av yog tag nrho nyob rau hauv ib txheej ntawm Feuerletten, nrog rau overburden ntawm 4 mus rau 20 m. Lub Feuerletten muaj cov av nplaum nrog cov xuab zeb zoo thiab nruab nrab ntawm cov xuab zeb, suav nrog cov xuab zeb ua ntu zus nrog cov tuab txog li 5 m thiab hloov cov xuab zeb-claystone txheej txheej txog li 10 m hauv qee qhov chaw. Lub qhov yog lined hla nws tag nrho ntev nrog ib tug ob chav reinforced sab hauv nplooj uas nws thickness nyob rau hauv pem teb txawv ntawm 75 cm thiab 125 cm thiab yog ib tug uniform 35 cm tuab nyob rau hauv lub vault.
Vim nws cov kev txawj ntse nyob rau hauv geotechnical daim ntaub ntawv, DSI Austria lub Salzburg ceg tau muab tsub lub daim ntawv cog lus rau cov khoom ntawm lub anchor systems. Anchoring raug tua siv 25 hli dia.500/550 SN thauj tog rau nkoj nrog ib tug dov-on ntsia hlau xov rau thauj tog rau nkoj txiv ntseej. Nyob rau hauv txhua 1 m ru tsev seem xya anchors nrog ib tug ntev ntawm plaub meters txhua tau ntsia rau hauv ib ncig ntawm lub pob zeb. Tsis tas li ntawd, DSI Hollow Bars tau teeb tsa los ua kom lub ntsej muag ua haujlwm ib ntus.
