2017年6月10日青島地鐵2號線(xian)(xian)石(shi)老人浴(yu)場站B出入口過香港(gang)東路暗(an)挖通(tong)(tong)道重(zhong)大(da)風(feng)險(xian)源順利(li)貫通(tong)(tong)，比計劃(hua)工(gong)期提前15天完成。暗(an)挖通(tong)(tong)道地質差，下穿(chuan)給水、燃氣、雨水、污水等(deng)多(duo)種管線(xian)(xian)，開(kai)挖風(feng)險(xian)極高，為地鐵2號線(xian)(xian)重(zhong)大(da)風(feng)險(xian)源之(zhi)一。

石老人浴場站B號(hao)出入口下(xia)穿香(xiang)港東路及(ji)海爾路。采用礦山法施工，此次順利貫(guan)通(tong)(tong)的為(wei)下(xia)穿香(xiang)港東路段通(tong)(tong)道，長度為(wei)36m，暗挖通(tong)(tong)道開挖過程中(zhong)穿越以含(han)淤(yu)泥中(zhong)粗(cu)砂、粉質黏土、中(zhong)粗(cu)砂及(ji)含(han)黏性土粗(cu)礫砂為(wei)主的第(di)四系表土層，圍巖級別為(wei)VI級，開挖風險極高(gao)。

建設(she)分公司在將(jiang)其列(lie)入(ru)重大風(feng)險源(yuan)管(guan)控(kong)后，嚴格落(luo)實“暗(an)挖(wa)(wa)三要素”、“五方驗收”等管(guan)理措施，每周(zhou)不(bu)定期(qi)巡查，對暗(an)挖(wa)(wa)通(tong)道動(dong)態管(guan)理、科學規劃，精心組織施工(gong)，確(que)保工(gong)序(xu)有(you)效銜接、資源(yuan)配置到(dao)位，扎實有(you)序(xu)地推進工(gong)程(cheng)建設(she)，截止目(mu)前，施工(gong)過程(cheng)中未發生(sheng)任何險情。下一步，建設(she)分公司將(jiang)繼續加強過海爾路暗(an)挖(wa)(wa)通(tong)道安全管(guan)理，確(que)保順利通(tong)過又一重大風(feng)險源(yuan)，為2號線(xian)東段年底通(tong)車打下堅實基礎。
