Ukwakhiwa kwe-ICE entsha ye-high-speed train, eyenzelwe ukukhawuleza ukuya kwi-300 km / h, iya kunciphisa ixesha lokuhamba phakathi kweMunich neNuremberg, izixeko ezibini ezinkulu zaseBavaria, ukususela ngoku ngaphezu kwemizuzu eyi-100 ukuya ngaphantsi kwemizuzu engama-60.
Emva kokugqitywa kwamacandelo ongezelelweyo phakathi kweNuremberg neBerlin, ixesha lokuhamba lonke ukusuka eMunich ukuya kwikomkhulu laseJamani liya kuthatha iiyure ze-4 endaweni yeeyure ze-6.5 zangoku. Isakhiwo esikhethekileyo ngaphakathi kwimida yeprojekthi yokwakha yi-tunnel ye-Göggelsbuch enobude obupheleleyo be-2,287 m. Le tonela inomnqamlezo opheleleyo wecandelo malunga
I-150 m2 kwaye iquka i-shaft yokuhlangula eneendlela ezimbini zokuphuma ngokukhawuleza kumbindi we-tunnel ifakwe ngokupheleleyo kuluhlu lwe-Feuerletten, kunye nomthwalo ongaphezu kwe-4 ukuya kwi-20 m. I-Feuerletten iqulathe ilitye lodongwe elinesanti ecikizekileyo nephakathi, equka ulandelelwano lwelitye lentlabathi elinobunzima obungafika kwi-5 m kunye nokutshintshwa kwelitye lentlabathi lodongwe ukuya kwi-10 m kwiindawo ezithile. Itonela ifakwe phezu kobude bayo bonke kunye negqabi langaphakathi eliqiniswe kabini elinobunzima obusezantsi buhluka phakathi kwe-75 cm kunye ne-125 cm kwaye iyunifomu ye-35 cm ubukhulu kwivault.
Ngenxa yobuchwephesha bayo kwizicelo ze-geotechnical, isebe le-DSI Ostriya e-Salzburg yanikezelwa ngekhontrakthi yokubonelela ngeenkqubo zeankile ezifunekayo. I-anchoring yenziwe kusetyenziswa i-25 mm dia.500/550 SN iiankile ezine-rolled-on screw thread ye-anchor nut. Kwicandelo ngalinye le-1 m yophahla ii-ankile ezisixhenxe ezinobude beemitha ezine inye nganye yafakelwe kwilitye elijikelezileyo. Ukongeza, ii-DSI Hollow Bars zafakelwa ukuzinzisa okwethutyana ubuso obusebenzayo.
