勁松三(san)路(lu)站(zhan)~勁松四(si)路(lu)站(zhan)區間（簡稱(cheng)：三(san)四(si)區間）為(wei)青(qing)島地鐵(tie)四(si)號(hao)線(xian)第13段正(zheng)線(xian)區間，正(zheng)線(xian)全(quan)長548m，右線(xian)大(da)里(li)程(cheng)全(quan)長171米。三(san)四(si)區間洞身主要穿越強風化花崗(gang)巖(yan)，少量穿越中、微風化花崗(gang)巖(yan)，穿越5條斷(duan)裂破碎帶，為(wei)Ⅴ、Ⅵ級圍巖(yan)，地質(zhi)較(jiao)差，地質(zhi)風險較(jiao)高(gao)。

為高效實(shi)現三(san)四(si)區間(jian)右線大里程(cheng)(cheng)的安全(quan)(quan)(quan)貫通，順利步入二襯仰拱施(shi)(shi)(shi)工(gong)(gong)(gong)，青島(dao)地(di)鐵集團(tuan)、青島(dao)市地(di)鐵四(si)號線公司組(zu)織施(shi)(shi)(shi)工(gong)(gong)(gong)單(dan)位(wei)中鐵十七局，多次組(zu)織專家論證優化施(shi)(shi)(shi)工(gong)(gong)(gong)方(fang)案，確保(bao)施(shi)(shi)(shi)工(gong)(gong)(gong)安全(quan)(quan)(quan)有序。在施(shi)(shi)(shi)工(gong)(gong)(gong)過程(cheng)(cheng)中，成立(li)專項工(gong)(gong)(gong)作小組(zu)，高效實(shi)現人(ren)材機的調配(pei)；在人(ren)員配(pei)置方(fang)面(mian)配(pei)備(bei)選(xuan)擇地(di)鐵隧(sui)道施(shi)(shi)(shi)工(gong)(gong)(gong)經驗(yan)豐富的施(shi)(shi)(shi)工(gong)(gong)(gong)隊伍(wu)；在工(gong)(gong)(gong)程(cheng)(cheng)質量(liang)把關中嚴格實(shi)行各(ge)工(gong)(gong)(gong)序自檢、互檢、交接檢的三(san)檢制度；在工(gong)(gong)(gong)程(cheng)(cheng)安全(quan)(quan)(quan)保(bao)障中成立(li)安全(quan)(quan)(quan)質量(liang)小組(zu)，對施(shi)(shi)(shi)工(gong)(gong)(gong)隊伍(wu)進行崗前安全(quan)(quan)(quan)質量(liang)培訓及技術交底，定期組(zu)織安全(quan)(quan)(quan)質量(liang)檢查，遇到(dao)問(wen)(wen)題現場(chang)解決，問(wen)(wen)責到(dao)底。

通過從(cong)人員配(pei)置、質量把關、安全保(bao)障等(deng)多方面的精心組織，青島地鐵4號(hao)線(xian)三四區間(jian)右線(xian)大里程順利(li)貫通，這標志著青島地鐵4號(hao)線(xian)的建設邁向了新的臺階。
