SCT zgradil dvocevni tripasovni predor Šentvid s kavernama in prikljunima cevema [Elektronski vir]Popit, Andreja ...Predorograditelji SCT smo v letih od 2004 do 2009 gradili dvocevni tripasovni predor Šentvid, ki je prvi predor v Sloveniji s kavernama in priključnima cevema ter velja za enega najzahtevnejših ... inženirskih objektov pri nas. Glavni predorski cevi v dolžini 1033 m (leva) in 1060 m (desna) povezujeta gorenjsko avtocesto z ljubljanskim avtocestnim obročem, priključni cevi v dolžini 345 m (leva eno- in dvopasovna) in 243 m (desna enopasovna) pa povezujeta glavni predorski cevi s Celovško cesto. Obe priključni cevi sta usmerjeni proti Medvodam, medtem ko bo usmerjanje proti Ljubljani mogoče šele po razširitvi in obnovi Celovške ceste, kar je predvideno do konca leta 2011. Z izgradnjo predora je bil promet na Celovški cesti bistveno razbremenjen, saj se skozi predor dnevno zapelje več kot 35 000 avtomobilov. Velik dosežek za predorograditelje SCT je, da smo predor s kaverno in priključnima cevema zgradili v mono tektoniziranih permokarbonskih kamninah. Predor smo gradili po novi avstrijski metodi, po kateri smo s kontinuirnim opazovanjem deformacij hribinske mase v okolici predora in premikov primarne predorske obloge preverjali stabilnost predora ter sproti prilagajali predvidene podporne ukrepe. Tako smo morali primarno predorsko oblogo v glavnih predorskih ceveh z dodatnimi sidri ojaati na 74 % dolžine leve in na 79 % dolžine desne predorske cevi. Zaradi mono tektonsko poškodovanih kamnin v trasi predora smo morali dodatno armirati vso notranjo oblogo predora, še posebej na odsekih z večjimi preseki (tripasovni predor, kaverni in odstavni niši). Za betoniranje notranje obloge smo uporabili kovinske in kovinskolesene opaže. Za zagotovitev prometne varnosti smo za primer evakuacije in intervencije na vsakih 250 m zgradili prenik, ki povezuje obe glavni cevi. Iz varnostnih razlogov smo tudi 345 m dolgo levo (izvozno) priključno cev s prenikom povezaliz levo glavno cevjo. Zgradili in ustrezno opremili smo parkirne niše, niše za klic v sili in protipožarne (hidrantne) niše, prometno varnost v predoru pa zagotovili tudi z vgradnjo najsodobnejše elektrostrojne opreme.Source: Referati [Elektronski vir] = Proceedings (Str. 1232-1249)Type of material - conference contributionPublish date - 2010Language - slovenianCOBISS.SI-ID - 35054341
