近日，華西集團所屬四川場(chang)道(dao)(dao)公(gong)司承建的成(cheng)都天府國際機場(chang)唯(wei)一(yi)的4F級(ji)跑道(dao)(dao)西一(yi)跑道(dao)(dao)迎來全線貫通(tong)，這(zhe)也(ye)是天府國際機場(chang)一(yi)期工程(cheng)三條跑道(dao)(dao)中(zhong)率先實現全線貫通(tong)的跑道(dao)(dao)。

西一跑道(dao)(dao)全(quan)長4000米(mi)，寬(kuan)75米(mi)，是“兩(liang)縱一橫(heng)”三條跑道(dao)(dao)中最(zui)長的(de)(de)一條，也是唯一可以起降空(kong)客A380的(de)(de)跑道(dao)(dao)。西一跑道(dao)(dao)混凝(ning)土道(dao)(dao)面(mian)(mian)工(gong)(gong)(gong)程于2019年10月(yue)開(kai)工(gong)(gong)(gong)建設，項(xiang)目(mu)(mu)自(zi)開(kai)工(gong)(gong)(gong)以來，面(mian)(mian)臨工(gong)(gong)(gong)期特別(bie)緊、任務特別(bie)重(zhong)的(de)(de)巨大(da)壓力，尤其是受(shou)新冠(guan)肺炎疫情影響，項(xiang)目(mu)(mu)更(geng)是錯過了黃金施工(gong)(gong)(gong)時(shi)(shi)間。為追回疫情影響的(de)(de)時(shi)(shi)間，項(xiang)目(mu)(mu)部自(zi)2月(yue)22日正式復工(gong)(gong)(gong)后，堅持(chi)防疫和施工(gong)(gong)(gong)生產兩(liang)手抓、兩(liang)手硬，采取(qu)全(quan)員放棄(qi)休假(jia)、增加作業(ye)班組、24小時(shi)(shi)不間斷施工(gong)(gong)(gong)作業(ye)等措(cuo)施，全(quan)面(mian)(mian)有(you)序(xu)加快施工(gong)(gong)(gong)進度，最(zui)終比計(ji)劃時(shi)(shi)間提前4天貫通(tong)。

在迅速推進施(shi)(shi)工(gong)(gong)進度的(de)(de)同時，西(xi)(xi)一(yi)跑(pao)(pao)道(dao)在推廣(guang)新(xin)技術、新(xin)工(gong)(gong)藝、新(xin)設備(bei)方面均有(you)重大突破。為避免發生混凝(ning)土板底脫(tuo)空(kong)現(xian)象，西(xi)(xi)一(yi)跑(pao)(pao)道(dao)采用道(dao)面瀝青復合(he)層(ceng)新(xin)型工(gong)(gong)藝施(shi)(shi)工(gong)(gong)，也是國內首(shou)條采用該工(gong)(gong)藝施(shi)(shi)工(gong)(gong)的(de)(de)跑(pao)(pao)道(dao)。該工(gong)(gong)藝通過(guo)在機場水(shui)泥(ni)混凝(ning)土道(dao)面層(ceng)與(yu)基層(ceng)之間設置瀝青復合(he)基隔(ge)離層(ceng)，達到(dao)隔(ge)離、防水(shui)、抗沖刷和應力緩沖等(deng)功(gong)能，可有(you)效(xiao)解決唧泥(ni)、脫(tuo)空(kong)、斷裂等(deng)病害，提高機場水(shui)泥(ni)混凝(ning)土道(dao)面長期使用性能。

成都天府(fu)國(guo)際機場西一跑道(dao)提(ti)前全線(xian)貫通，為(wei)下一步的(de)助航燈光、道(dao)面標志線(xian)等施工(gong)創造了(le)有(you)利條(tiao)件，為(wei)后續校飛(fei)、試(shi)飛(fei)、行業驗收等一系列相關工(gong)作(zuo)提(ti)供了(le)有(you)力保障。

除西一跑道(dao)道(dao)面工(gong)程外，天府國際(ji)機場飛(fei)行區場道(dao)工(gong)程01標段內(nei)的(de)滑行道(dao)、聯(lian)絡道(dao)、站坪及(ji)相關配套工(gong)程正在全面加快推進，預計今年7月(yue)底前(qian)完成混(hun)凝土施工(gong)，9月(yue)30日前(qian)達到竣(jun)工(gong)驗收條件，為2020年11月(yue)完成校飛(fei)提(ti)供有力支撐。
