11月(yue)30日，由中國中鐵及(ji)所(suo)屬單位參建的(de)廣(guang)(guang)(guang)清城(cheng)際(ji)、廣(guang)(guang)(guang)州東環城(cheng)際(ji)同日開通(tong)運營，標志著(zhu)廣(guang)(guang)(guang)州、清遠(yuan)兩個(ge)城(cheng)市迎來了一軌雙城(cheng)，廣(guang)(guang)(guang)清一體化(hua)交通(tong)體系將更加快捷便利。

廣(guang)清(qing)(qing)城(cheng)(cheng)際、廣(guang)州東(dong)環(huan)城(cheng)(cheng)際作(zuo)為粵港澳大(da)灣區城(cheng)(cheng)際鐵(tie)路(lu)(lu)網的重要(yao)組成部分(fen)，同時(shi)也是廣(guang)東(dong)省首批省方獨資(zi)建設、自(zi)主運營的鐵(tie)路(lu)(lu)項目。此次(ci)開通的廣(guang)清(qing)(qing)城(cheng)(cheng)際花(hua)(hua)(hua)都(dou)(dou)至清(qing)(qing)城(cheng)(cheng)段線路(lu)(lu)全長38.2公(gong)里(li)，共設6個車(che)(che)站(zhan)(zhan)(zhan)，其中花(hua)(hua)(hua)都(dou)(dou)站(zhan)(zhan)(zhan)、樂同站(zhan)(zhan)(zhan)為地面站(zhan)(zhan)(zhan)，獅(shi)嶺站(zhan)(zhan)(zhan)、銀盞(zhan)站(zhan)(zhan)(zhan)、龍塘鎮站(zhan)(zhan)(zhan)、清(qing)(qing)城(cheng)(cheng)站(zhan)(zhan)(zhan)為高架站(zhan)(zhan)(zhan)，列車(che)(che)最高速(su)度(du)每小時(shi)200公(gong)里(li)；廣(guang)州東(dong)環(huan)城(cheng)(cheng)際花(hua)(hua)(hua)都(dou)(dou)至白云(yun)機(ji)場(chang)北(bei)段線路(lu)(lu)全長22.6公(gong)里(li)，共設4個車(che)(che)站(zhan)(zhan)(zhan)，花(hua)(hua)(hua)都(dou)(dou)站(zhan)(zhan)(zhan)為地面站(zhan)(zhan)(zhan)，花(hua)(hua)(hua)城(cheng)(cheng)街站(zhan)(zhan)(zhan)、花(hua)(hua)(hua)山(shan)鎮站(zhan)(zhan)(zhan)、白云(yun)機(ji)場(chang)北(bei)站(zhan)(zhan)(zhan)為地下站(zhan)(zhan)(zhan)，列車(che)(che)最高速(su)度(du)每小時(shi)160公(gong)里(li)。

中(zhong)(zhong)(zhong)國中(zhong)(zhong)(zhong)鐵作為城(cheng)市(shi)軌(gui)道(dao)交通(tong)建設(she)主力(li)軍，在(zai)廣(guang)清城(cheng)際(ji)、廣(guang)州(zhou)東環城(cheng)際(ji)建設(she)中(zhong)(zhong)(zhong)充(chong)分(fen)發揮全產(chan)業鏈一體化的綜(zong)合優勢，所屬(shu)中(zhong)(zhong)(zhong)鐵一局、四(si)局、七局、八(ba)局、電(dian)(dian)(dian)氣化局、廣(guang)州(zhou)局等(deng)單位(wei)全面參建了(le)路(lu)基、橋涵(han)、隧道(dao)、地下車站結構、房屋(wu)建筑、軌(gui)道(dao)、電(dian)(dian)(dian)力(li)牽引供電(dian)(dian)(dian)、電(dian)(dian)(dian)力(li)、通(tong)信、信號及(ji)其(qi)它站后(hou)工程(cheng)等(deng)。

施工(gong)(gong)(gong)過程(cheng)中，項(xiang)目(mu)部首次運用連續梁(liang)橋墩頂轉體施工(gong)(gong)(gong)工(gong)(gong)(gong)藝(yi)等多項(xiang)新(xin)(xin)技術、新(xin)(xin)工(gong)(gong)(gong)藝(yi)，創(chuang)造了(le)同類型轉體梁(liang)之最，節約了(le)5個月的工(gong)(gong)(gong)期，并大幅(fu)降低(di)了(le)鐵路(lu)、公路(lu)的運營安(an)全風險。同時，為確保隧道仰拱施工(gong)(gong)(gong)質量(liang)，項(xiang)目(mu)部改進自(zi)行式液(ye)壓仰拱臺車(che)、固(gu)定環向止水(shui)帶二襯鋼端(duan)模、矮邊墻縱向鋼邊止水(shui)帶固(gu)定裝置(zhi)、軌行式水(shui)溝電纜槽臺車(che)等新(xin)(xin)工(gong)(gong)(gong)藝(yi)及工(gong)(gong)(gong)裝設備(bei)，研(yan)制開發了(le)接觸網(wang)腕臂和(he)吊弦(xian)預制平臺，實現了(le)施工(gong)(gong)(gong)作(zuo)業(ye)機械化、施工(gong)(gong)(gong)技術模塊化，使施工(gong)(gong)(gong)效率大幅(fu)提升，進一步彰顯了(le)企(qi)業(ye)硬核實力。

據悉，廣清城際、廣州(zhou)(zhou)東環城際建(jian)成通車(che)后，隨(sui)著廣州(zhou)(zhou)北(bei)站和白云機(ji)場兩大綜合交通樞(shu)紐及廣清南、北(bei)延(yan)線的建(jian)設(she)，廣清軌道(dao)交通建(jian)設(she)將進入新發(fa)展階段，對于(yu)加快廣州(zhou)(zhou)東北(bei)部(bu)交通基礎設(she)施建(jian)設(she)，開啟“空鐵聯運”進程，推動廣州(zhou)(zhou)、清遠區域經濟(ji)一體化發(fa)展具有(you)重要意義。
