4月30日下午13時，在(zai)位于(yu)青(qing)海省海南藏族自治州貴南縣森(sen)多鎮(zhen)境內的N419號牽引場上，隨著最后6根(gen)1250平方(fang)毫米大截面導線的順(shun)利牽引到位，標(biao)志(zhi)著由青(qing)海送變電工(gong)(gong)程(cheng)(cheng)有(you)限公司承建的“青(qing)豫”特(te)高壓線路(lu)工(gong)(gong)程(cheng)(cheng)（青(qing)2標(biao)段）架(jia)線全(quan)線貫通，按計劃(hua)完(wan)成架(jia)線施工(gong)(gong)任務，為確保工(gong)(gong)程(cheng)(cheng)6月30日投運奠定了堅實的基礎。

“青(qing)豫”特高(gao)壓(ya)工(gong)程是世(shi)界(jie)首條(tiao)專為(wei)清潔能(neng)(neng)源外送而建設的特高(gao)壓(ya)通道，也(ye)是支撐青(qing)海省新能(neng)(neng)源大(da)規模開發規劃建設的第一條(tiao)特高(gao)壓(ya)輸電(dian)(dian)通道。這(zhe)項世(shi)界(jie)上首個以(yi)服務光伏(fu)發電(dian)(dian)為(wei)主、全清潔能(neng)(neng)源打捆外送特高(gao)壓(ya)工(gong)程自(zi)復工(gong)以(yi)來，青(qing)海段施(shi)工(gong)加速(su)推進(jin)，跑出了復工(gong)復產的“加速(su)度”，有效帶動了電(dian)(dian)網上下游產業鏈(lian)恢(hui)復并(bing)提升產能(neng)(neng)，成(cheng)為(wei)穩定(ding)地方經(jing)濟增(zeng)長的助推器。

為確(que)(que)保(bao)工(gong)(gong)(gong)程(cheng)建設(she)安(an)全(quan)、有序推進(jin)，國網青(qing)(qing)海省電(dian)力公司提(ti)前策劃(hua)、科(ke)學部(bu)署(shu)、精(jing)細(xi)施(shi)(shi)工(gong)(gong)(gong)，組織青(qing)(qing)海送變(bian)電(dian)公司和施(shi)(shi)工(gong)(gong)(gong)項(xiang)目部(bu)召開架線(xian)(xian)施(shi)(shi)工(gong)(gong)(gong)分析(xi)會，根據地形情況擇優劃(hua)分架線(xian)(xian)施(shi)(shi)工(gong)(gong)(gong)區(qu)段，精(jing)確(que)(que)計算(suan)牽(qian)張(zhang)力并復核(he)機具配(pei)套(tao)情況，重點把控直線(xian)(xian)塔垂直荷載及各轉角塔受力、預偏、上(shang)揚等，并針對性做好(hao)相(xiang)應的安(an)全(quan)防控措施(shi)(shi)。

國網青海省電力(li)公(gong)司在(zai)工(gong)(gong)(gong)(gong)程建設中全(quan)過程落實安全(quan)質(zhi)量(liang)和工(gong)(gong)(gong)(gong)程創(chuang)優規劃(hua)，著力(li)打(da)造新時(shi)代(dai)“樣板工(gong)(gong)(gong)(gong)程”和“安全(quan)智慧工(gong)(gong)(gong)(gong)地”。作為施工(gong)(gong)(gong)(gong)單位的(de)青海送(song)變電參(can)(can)建人員克服高寒缺(que)氧(yang)、環境氣候惡劣、架(jia)線材(cai)料運輸(shu)難等困(kun)難，組織技術人員對架(jia)線施工(gong)(gong)(gong)(gong)方(fang)案、施工(gong)(gong)(gong)(gong)現場進行了多次(ci)論(lun)證和勘查(cha)，同時(shi)參(can)(can)照(zhao)地形高差影響，最終決定采用“3×一牽2”張力(li)架(jia)線施工(gong)(gong)(gong)(gong)方(fang)案。

該架線方(fang)式(shi)最(zui)大(da)(da)優點(dian)就(jiu)是減少了工器具的投(tou)入，提(ti)高(gao)了現有設備的利用(yong)(yong)率(lv)，使架線工效提(ti)高(gao)了20％左右(you)。架線始終采用(yong)(yong)無人機展放(fang)引繩施工方(fang)法(fa)，具有安全、經(jing)濟(ji)、可靠等優點(dian)，為工程的最(zui)終全線貫通提(ti)供了強大(da)(da)的技(ji)術支(zhi)撐。

“青豫特高壓工程最大的施(shi)(shi)工難點(dian)和技術難點(dian)均體現(xian)在(zai)架線(xian)(xian)施(shi)(shi)工階段(duan)。為了(le)(le)解決導(dao)線(xian)(xian)同步展(zhan)放(fang)難題，我們專(zhuan)門加(jia)工了(le)(le)放(fang)線(xian)(xian)滑車專(zhuan)用掛板，既方便了(le)(le)導(dao)線(xian)(xian)放(fang)線(xian)(xian)滑車的懸掛，又確保(bao)了(le)(le)緊線(xian)(xian)時6根子導(dao)線(xian)(xian)相(xiang)對水(shui)平(ping)，同時還能確保(bao)導(dao)線(xian)(xian)牽引板順利安全的通過(guo)放(fang)線(xian)(xian)滑車。”青豫特高壓（青2標段(duan)）項(xiang)目(mu)經(jing)理李積存說道。

自工(gong)(gong)程(cheng)建(jian)設以來，國網青海(hai)省電(dian)力(li)公(gong)司始(shi)終(zhong)以建(jian)設新(xin)時代(dai)“樣板(ban)工(gong)(gong)程(cheng)”為目標。針(zhen)對沼澤地施工(gong)(gong)這一(yi)困難采(cai)用鋪設鋼(gang)板(ban)修(xiu)筑施工(gong)(gong)通道的(de)(de)(de)(de)方式(shi)修(xiu)建(jian)25千米的(de)(de)(de)(de)施工(gong)(gong)通道，累計投(tou)入鋼(gang)板(ban)4000多塊，在(zai)加快施工(gong)(gong)進度的(de)(de)(de)(de)同時有(you)效保護(hu)了脆弱(ruo)的(de)(de)(de)(de)生態(tai)環境。在(zai)工(gong)(gong)程(cheng)建(jian)設中成立臨時黨(dang)(dang)支(zhi)部，結(jie)合工(gong)(gong)程(cheng)建(jian)設多次組(zu)織形(xing)式(shi)多樣的(de)(de)(de)(de)“黨(dang)(dang)建(jian)+”系列活(huo)動(dong)，充分發揮現場(chang)黨(dang)(dang)員先鋒(feng)模(mo)范作用，組(zu)織開展“建(jian)和諧(xie)管理(li)團隊(dui)，創(chuang)國優精品工(gong)(gong)程(cheng)”活(huo)動(dong)和“六賽一(yi)創(chuang)”勞動(dong)競(jing)賽等活(huo)動(dong)，依托黨(dang)(dang)建(jian)工(gong)(gong)作的(de)(de)(de)(de)新(xin)成效助(zhu)推工(gong)(gong)程(cheng)各項建(jian)設工(gong)(gong)作快速、有(you)序推進。

新冠肺炎(yan)疫情發(fa)生(sheng)以來，國(guo)網青海省電力公司堅決(jue)貫(guan)徹落實國(guo)家電網有限(xian)公司黨(dang)組提出(chu)的“兩(liang)手抓、兩(liang)不誤、兩(liang)促(cu)進”工(gong)(gong)作要求，精(jing)心組織(zhi)協調，于(yu)2月23日全面(mian)復工(gong)(gong)建(jian)(jian)設，發(fa)揮大(da)國(guo)重器(qi)的頂(ding)梁柱作用，在(zai)科學有序(xu)復工(gong)(gong)復產上做示范，在(zai)全力防控疫情的同時(shi)，堅持目標不變、任務(wu)不減，精(jing)心組織(zhi)、科學管(guan)理、攻堅克難，多舉措落實各方面(mian)資源和要素配置，快速推進特高壓工(gong)(gong)程復工(gong)(gong)建(jian)(jian)設，目前工(gong)(gong)程各項施工(gong)(gong)進度均(jun)處于(yu)可控、受控狀態。

下一步(bu)，國網(wang)青(qing)海省電力公司將繼續(xu)狠抓現場安(an)全管控，嚴格落(luo)(luo)實各項安(an)全、質量保證措施(shi)，嚴格落(luo)(luo)實各級職責，認真(zhen)做(zuo)好(hao)三級自檢制度，全力確保青(qing)豫(yu)特(te)高壓工程按期投(tou)運。
