近日，中鐵五局施工的渝湘高速公路彭武段特長隧道——中興隧道左線主體工程全部完工。
渝(yu)湘(xiang)高(gao)(gao)速(su)公(gong)(gong)路是國家規劃的(de)“7918”高(gao)(gao)速(su)公(gong)(gong)路網中(zhong)包(bao)頭至茂名公(gong)(gong)路的(de)重(zhong)(zhong)要組(zu)成部分(fen)，也是國家西部開(kai)發(fa)的(de)八大(da)省(sheng)際通道(dao)(dao)之一。中(zhong)興隧(sui)道(dao)(dao)總(zong)長為(wei)(wei)12.187公(gong)(gong)里(li)，其中(zhong)左線(xian)單幅長6105米(mi)，右線(xian)單幅長6082米(mi)，為(wei)(wei)雙(shuang)洞分(fen)修特(te)長隧(sui)道(dao)(dao)。全線(xian)采用4車道(dao)(dao)高(gao)(gao)速(su)公(gong)(gong)路標準建設(she)，是位于重(zhong)(zhong)慶(qing)至武隆段全線(xian)重(zhong)(zhong)難(nan)點控制(zhi)性工(gong)(gong)(gong)程(cheng)，也是彭武段最長最難(nan)的(de)重(zhong)(zhong)難(nan)點隧(sui)道(dao)(dao)。中(zhong)興隧(sui)道(dao)(dao)集斷(duan)層(ceng)破碎帶、大(da)涌(yong)水(shui)、煤層(ceng)瓦(wa)斯(si)、溶(rong)洞群為(wei)(wei)一體。自(zi)開(kai)工(gong)(gong)(gong)以來，中(zhong)鐵五(wu)局(ju)嚴格(ge)現(xian)場管理(li)，科學(xue)組(zu)織，積極開(kai)展科技攻關。先后攻克(ke)了244米(mi)長的(de)特(te)大(da)斷(duan)層(ceng)破碎帶、溶(rong)洞群、瓦(wa)斯(si)、涌(yong)水(shui)等(deng)施工(gong)(gong)(gong)難(nan)題，戰(zhan)勝(sheng)了百年(nian)難(nan)遇(yu)的(de)洪災(zai)、干旱、暴(bao)雪等(deng)自(zi)然災(zai)害給施工(gong)(gong)(gong)生(sheng)(sheng)產(chan)帶來的(de)重(zhong)(zhong)重(zhong)(zhong)困難(nan)。堅持安全生(sheng)(sheng)產(chan)，強化現(xian)場管理(li)，嚴格(ge)有序組(zu)織，狠抓過(guo)程(cheng)控制(zhi)，確保了中(zhong)興隧(sui)道(dao)(dao)左線(xian)提前30天實現(xian)順利貫通。
