11月24日，隨著車公廟右線(xian)最后一節軌排(pai)混凝土(tu)的(de)澆筑(zhu)完(wan)成，由(you)中國建(jian)筑(zhu)投(tou)資建(jian)設的(de)深圳地鐵9號線(xian)軌道工程全線(xian)實現雙(shuang)線(xian)軌通。

深圳(zhen)地鐵9號線(xian)(xian)正線(xian)(xian)全(quan)長逾25公里(li)，設車站22座，其中(zhong)換乘站10座。它是深圳(zhen)市實現“南北貫通、東拓西聯(lian)”、“中(zhong)心強化、兩翼(yi)伸(shen)展(zhan)”空間(jian)(jian)發展(zhan)策略、形成(cheng)“三軸兩帶、多中(zhong)心”城(cheng)市空間(jian)(jian)布局(ju)結構、緩解交通擁堵、實現城(cheng)市綜合交通和(he)公共交通發展(zhan)戰略的骨干線(xian)(xian)路。

9號(hao)線工(gong)(gong)(gong)(gong)(gong)程(cheng)在(zai)深圳在(zai)施(shi)(shi)的(de)(de)三條地鐵(tie)中工(gong)(gong)(gong)(gong)(gong)藝最復雜，工(gong)(gong)(gong)(gong)(gong)期最短，施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)難度(du)大。鋪(pu)軌(gui)(gui)過程(cheng)中，中國(guo)建筑(zhu)創新多(duo)項施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)技(ji)術(shu)：一是鋪(pu)軌(gui)(gui)采用(yong)減振(zhen)道(dao)床技(ji)術(shu)，減少了(le)(le)列車(che)(che)運行(xing)時產生(sheng)的(de)(de)噪音，并且(qie)深圳市(shi)范圍內(nei)首次采用(yong)浮置(zhi)板(ban)道(dao)床在(zai)廠內(nei)預(yu)制的(de)(de)方法，現場直接安裝，有(you)效地保證了(le)(le)浮置(zhi)板(ban)的(de)(de)施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)質量，提高了(le)(le)施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)效率；二是安裝帶滾(gun)輪(lun)系統的(de)(de)曲(qu)尖(jian)軌(gui)(gui)道(dao)岔，既提高了(le)(le)列車(che)(che)通過道(dao)岔的(de)(de)速度(du)，又增加了(le)(le)道(dao)岔的(de)(de)使(shi)(shi)用(yong)壽命(ming)；三是在(zai)全(quan)國(guo)地鐵(tie)施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)領域，率先采用(yong)高鐵(tie)的(de)(de)精(jing)調技(ji)術(shu)CPIII控(kong)制測(ce)量網，使(shi)(shi)軌(gui)(gui)道(dao)幾何尺寸(cun)達到了(le)(le)高鐵(tie)標準，確保了(le)(le)列車(che)(che)運營(ying)安全(quan)和(he)軌(gui)(gui)道(dao)幾何尺寸(cun)的(de)(de)圓順性，提高了(le)(le)市(shi)民(min)乘(cheng)車(che)(che)的(de)(de)舒適度(du)。
