近日，中國鐵路工程總公司所屬中鐵隧道集團承建的寧波市軌道交通1號線TJ-Ⅱ標西門口地鐵車站主體圍護結構順利完工。
西門口站(zhan)地(di)(di)處(chu)寧波市中(zhong)(zhong)心城區(qu)，居民樓(lou)密集(ji)，南(nan)側淺基(ji)(ji)礎(chu)建(jian)筑物(wu)多，距離圍護結(jie)構近(jin)，南(nan)側地(di)(di)層(ceng)中(zhong)(zhong)軟土(tu)(tu)層(ceng)較厚，地(di)(di)下(xia)障礙物(wu)多，地(di)(di)基(ji)(ji)強度(du)低(di)、穩定性差。對此，中(zhong)(zhong)鐵隧(sui)道集(ji)團(tuan)多次召開(kai)(kai)專家討論會，成立了(le)“信息(xi)化施(shi)(shi)工(gong)(gong)(gong)(gong)管理小組”，對南(nan)側地(di)(di)表(biao)(biao)及建(jian)筑物(wu)進行(xing)實時(shi)(shi)監測，通(tong)過優(you)化施(shi)(shi)工(gong)(gong)(gong)(gong)方案(an)，合(he)理安排施(shi)(shi)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)序，將(jiang)建(jian)筑物(wu)沉(chen)降值控制(zhi)在允(yun)許范圍內；通(tong)過對施(shi)(shi)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)序、作業時(shi)(shi)間、文明施(shi)(shi)工(gong)(gong)(gong)(gong)等(deng)進行(xing)規范化管理，將(jiang)噪聲污染降至最(zui)(zui)低(di)，保證了(le)居民正常的生(sheng)活質(zhi)量；針對南(nan)側不(bu)良地(di)(di)質(zhi)影響，提出三軸(zhou)水泥(ni)土(tu)(tu)攪拌樁加固地(di)(di)連墻(qiang)外側土(tu)(tu)體，再配(pei)合(he)信息(xi)化施(shi)(shi)工(gong)(gong)(gong)(gong)管理，有效控制(zhi)了(le)南(nan)側地(di)(di)表(biao)(biao)、建(jian)筑物(wu)沉(chen)降，保證了(le)地(di)(di)連墻(qiang)施(shi)(shi)工(gong)(gong)(gong)(gong)安全。最(zui)(zui)終順(shun)利(li)完成這一節(jie)點性施(shi)(shi)工(gong)(gong)(gong)(gong)任(ren)務，為(wei)后(hou)續車站(zhan)冠梁、混凝土(tu)(tu)支(zhi)撐施(shi)(shi)工(gong)(gong)(gong)(gong)及基(ji)(ji)坑開(kai)(kai)挖奠定了(le)堅實的基(ji)(ji)礎(chu)。
