2015年9月(yue)22日(ri)上午(wu)9點58分(fen)麥徐(xu)區(qu)間礦山(shan)法(fa)段(duan)二襯(chen)(chen)混(hun)凝土開始(shi)首次澆筑，標志(zhi)著青島地鐵(tie)2號線(xian)麥徐(xu)區(qu)間開始(shi)二襯(chen)(chen)施工。

青島(dao)地(di)鐵(tie)2號(hao)線(xian)土建(jian)二(er)標02工(gong)區(qu)麥島(dao)站麥徐(xu)區(qu)間(jian)礦山(shan)法段(duan)由(you)中國(guo)鐵(tie)建(jian)十八(ba)局集(ji)團公(gong)(gong)司承建(jian)，上海(hai)天佑工(gong)程咨(zi)詢有限(xian)公(gong)(gong)司負責監理，單(dan)洞(dong)長(chang)218.2m，該(gai)(gai)區(qu)間(jian)為TBM接(jie)收洞(dong)，同(tong)時(shi)地(di)鐵(tie)5號(hao)線(xian)將從該(gai)(gai)區(qu)間(jian)接(jie)出。麥徐(xu)區(qu)間(jian)礦山(shan)法段(duan)二(er)襯(chen)混凝土澆筑采用二(er)襯(chen)臺車施(shi)工(gong)。由(you)于(yu)麥徐(xu)區(qu)間(jian)位于(yu)麥島(dao)站東端(duan)，和(he)麥島(dao)站同(tong)時(shi)開挖(wa)施(shi)工(gong)，工(gong)期緊(jin)，施(shi)工(gong)場(chang)地(di)狹窄(zhai)，場(chang)地(di)作業面多(duo)，這些對開挖(wa)掘進(jin)和(he)技術管理都提出了很高(gao)(gao)的要求；該(gai)(gai)洞(dong)大部分地(di)段(duan)位于(yu)花崗巖地(di)層，巖石強度高(gao)(gao)（最高(gao)(gao)202Mpa），石英(ying)含量高(gao)(gao)，技術風險和(he)安全風險大。

在施(shi)工(gong)(gong)(gong)過程(cheng)中，技術人員精心組織、合理(li)安(an)排工(gong)(gong)(gong)序，克服區間左右線(xian)和麥島(dao)站交(jiao)叉施(shi)工(gong)(gong)(gong)、洞內出渣困難(nan)、施(shi)工(gong)(gong)(gong)場地(di)狹(xia)小(xiao)等困難(nan)，確保工(gong)(gong)(gong)程(cheng)順利(li)推進。為TBM進入麥島(dao)站做好前期(qi)準(zhun)備，為TBM有序施(shi)工(gong)(gong)(gong)奠定了堅(jian)實的基礎。
