　　3月12日，由中鐵(tie)國際(ji)牽頭，中鐵(tie)裝(zhuang)備(bei)聯合中鐵(tie)科工(gong)共(gong)同研(yan)制的(de)綠色裝(zhuang)配式(shi)綜合管廊施工(gong)設備(bei)"紫荊號"U盾(dun)架管機在(zai)香港元朗南第一期(qi)發(fa)展工(gong)程正(zheng)式(shi)始(shi)發(fa)。這款創新(xin)性(xing)融合盾(dun)構與(yu)架管技術的(de)新(xin)裝(zhuang)備(bei)，采用一體化施工(gong)模式(shi)，在(zai)提(ti)升(sheng)地下管網(wang)建設效率的(de)同時(shi)，將為香港城市基礎設施升(sheng)級提(ti)供全新(xin)解決方案。

　　此次始發的(de)“紫荊號”UTBM，寬9.36米(mi)，高20.72米(mi)，針(zhen)對(dui)香港北(bei)部(bu)都(dou)會(hui)區(qu)基礎建設項目量身打(da)造的(de)。該項目掘進(jin)總長(chang)1000米(mi)，施(shi)工(gong)(gong)(gong)地為砂質(zhi)(zhi)粉質(zhi)(zhi)黏土(tu)地質(zhi)(zhi)，周邊地下水(shui)充(chong)沛(pei)，且局部(bu)地段含淤泥較(jiao)多。針(zhen)對(dui)項目傳統(tong)明挖法施(shi)工(gong)(gong)(gong)風險系數高、施(shi)工(gong)(gong)(gong)圍擋(dang)占地大等問題，中鐵裝備結(jie)合(he)U型盾構在地下管廊(lang)的(de)成功應用經驗，將盾構與架(jia)管機進(jin)行創新(xin)(xin)性融(rong)合(he)，實現了(le)綜合(he)管廊(lang)運輸、開挖、支護(hu)、掘進(jin)、架(jia)設、側縫填充(chong)一體化高效施(shi)工(gong)(gong)(gong)，為裝配式綜合(he)管廊(lang)機械化施(shi)工(gong)(gong)(gong)帶(dai)來了(le)技術新(xin)(xin)突破。

　　“紫荊號”UTBM的應用(yong)(yong)具(ju)有顯著(zhu)的技(ji)(ji)術優勢和重(zhong)(zhong)要意(yi)義。從技(ji)(ji)術革新角度(du)看，該(gai)設(she)備的施(shi)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)法與傳統的明挖(wa)施(shi)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)法相(xiang)比，顯著(zhu)提(ti)升了(le)施(shi)工(gong)(gong)(gong)(gong)的機械化程度(du)與安(an)全性能，施(shi)工(gong)(gong)(gong)(gong)速(su)度(du)快，施(shi)工(gong)(gong)(gong)(gong)范圍(wei)(wei)小，不(bu)用(yong)(yong)施(shi)做圍(wei)(wei)護(hu)樁，出(chu)渣少(shao)，噪聲振動小，對(dui)周邊環境的影響(xiang)小等技(ji)(ji)術優勢。就(jiu)社會效益而言(yan)，該(gai)設(she)備的應用(yong)(yong)將有效緩(huan)解(jie)市(shi)政工(gong)(gong)(gong)(gong)程施(shi)工(gong)(gong)(gong)(gong)對(dui)香(xiang)(xiang)港(gang)土(tu)地資源(yuan)的擠占，在(zai)(zai)(zai)保證(zheng)施(shi)工(gong)(gong)(gong)(gong)順利(li)的同(tong)時(shi)，不(bu)影響(xiang)香(xiang)(xiang)港(gang)市(shi)民出(chu)行(xing)。在(zai)(zai)(zai)施(shi)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)藝突(tu)破(po)方面(mian)，該(gai)設(she)備在(zai)(zai)(zai)“盾架”一(yi)體化施(shi)工(gong)(gong)(gong)(gong)技(ji)(ji)術、抗滑移支(zhi)撐技(ji)(ji)術、皮(pi)帶機連續出(chu)渣同(tong)步回填(tian)技(ji)(ji)術、富水軟弱基礎換填(tian)技(ji)(ji)術等方面(mian)實現重(zhong)(zhong)要突(tu)破(po)，將為香(xiang)(xiang)港(gang)基礎設(she)施(shi)建設(she)提(ti)供(gong)更(geng)加安(an)全、高效、經濟、環保的施(shi)工(gong)(gong)(gong)(gong)解(jie)決方案。

　　“紫荊號”UTBM作為(wei)中鐵裝備(bei)首臺應(ying)用于香港市場的(de)大型(xing)設備(bei)，核心組件(jian)均滿足CE標準要求，整體設計得到香港地區監(jian)理公司Aecom的(de)認可。伴隨著設備(bei)的(de)成功始發(fa)，“紫荊號”UTBM為(wei)香港未(wei)來(lai)城市基建(jian)提供了可復用的(de)綠色施工范(fan)例。
