4月(yue)30日下午13時，在(zai)位(wei)(wei)于青(qing)海(hai)省海(hai)南藏族自治州貴南縣森多鎮境內的N419號牽(qian)引場上，隨(sui)著(zhu)最后6根1250平方毫米(mi)大截面導線(xian)(xian)的順利(li)牽(qian)引到位(wei)(wei)，標志著(zhu)由(you)青(qing)海(hai)送變電工程有限公司承建(jian)的“青(qing)豫”特高壓線(xian)(xian)路(lu)工程（青(qing)2標段）架線(xian)(xian)全線(xian)(xian)貫(guan)通(tong)，按計劃完成架線(xian)(xian)施工任務，為確保工程6月(yue)30日投運(yun)奠(dian)定了堅實的基(ji)礎。

“青(qing)豫”特高(gao)壓(ya)(ya)工程(cheng)是世界首條專為(wei)清(qing)(qing)潔能源(yuan)外送而建(jian)設(she)的(de)(de)特高(gao)壓(ya)(ya)通道(dao)，也是支撐青(qing)海(hai)省新能源(yuan)大規模(mo)開發規劃建(jian)設(she)的(de)(de)第一(yi)條特高(gao)壓(ya)(ya)輸(shu)電(dian)通道(dao)。這(zhe)項世界上首個以服務(wu)光伏發電(dian)為(wei)主、全清(qing)(qing)潔能源(yuan)打捆外送特高(gao)壓(ya)(ya)工程(cheng)自復工以來，青(qing)海(hai)段(duan)施工加(jia)速(su)推進，跑(pao)出了(le)復工復產(chan)的(de)(de)“加(jia)速(su)度”，有效帶動(dong)了(le)電(dian)網上下(xia)游產(chan)業鏈恢復并(bing)提升產(chan)能，成(cheng)為(wei)穩定地方經(jing)濟增(zeng)長的(de)(de)助推器。

為確保工程建(jian)設安(an)(an)全(quan)、有(you)序推(tui)進(jin)，國網青海(hai)(hai)省(sheng)電力公(gong)司(si)提(ti)前策(ce)劃、科(ke)學部署、精細施(shi)工，組織青海(hai)(hai)送變電公(gong)司(si)和(he)施(shi)工項目(mu)部召(zhao)開架線(xian)施(shi)工分(fen)析會，根據地形情(qing)況擇優劃分(fen)架線(xian)施(shi)工區(qu)段(duan)，精確計算(suan)牽(qian)張力并復核機具配(pei)套(tao)情(qing)況，重(zhong)點把控(kong)直(zhi)線(xian)塔垂直(zhi)荷載(zai)及各轉角(jiao)塔受力、預(yu)偏、上(shang)揚等，并針對性(xing)做好(hao)相應的安(an)(an)全(quan)防控(kong)措施(shi)。

國(guo)網(wang)青(qing)海(hai)省電力(li)(li)公司在工(gong)(gong)(gong)程(cheng)建設中(zhong)全(quan)過程(cheng)落實(shi)安(an)全(quan)質量和(he)(he)工(gong)(gong)(gong)程(cheng)創優規劃，著(zhu)力(li)(li)打(da)造新時(shi)代“樣板工(gong)(gong)(gong)程(cheng)”和(he)(he)“安(an)全(quan)智慧工(gong)(gong)(gong)地”。作(zuo)為施(shi)(shi)工(gong)(gong)(gong)單位的(de)青(qing)海(hai)送(song)變電參建人員(yuan)克服(fu)高寒缺氧、環境氣候惡劣、架線材料運(yun)輸難等困難，組織技術人員(yuan)對架線施(shi)(shi)工(gong)(gong)(gong)方案(an)、施(shi)(shi)工(gong)(gong)(gong)現場進行(xing)了多次論證和(he)(he)勘查，同時(shi)參照地形高差影(ying)響，最終決定采用“3×一牽2”張力(li)(li)架線施(shi)(shi)工(gong)(gong)(gong)方案(an)。

該架(jia)(jia)線(xian)(xian)方式最(zui)大優(you)點(dian)就是減少了(le)工(gong)器具的投(tou)入，提(ti)(ti)(ti)高了(le)現有(you)設備的利用(yong)率，使架(jia)(jia)線(xian)(xian)工(gong)效提(ti)(ti)(ti)高了(le)20％左右(you)。架(jia)(jia)線(xian)(xian)始終采用(yong)無人機展放引(yin)繩施工(gong)方法，具有(you)安全、經濟(ji)、可靠等優(you)點(dian)，為工(gong)程的最(zui)終全線(xian)(xian)貫通提(ti)(ti)(ti)供了(le)強(qiang)大的技術支撐。

“青(qing)豫特(te)高壓工程最(zui)大(da)的(de)施(shi)工難(nan)點和(he)技術難(nan)點均體現在(zai)架線(xian)(xian)(xian)施(shi)工階(jie)段(duan)(duan)。為了(le)解(jie)決導(dao)線(xian)(xian)(xian)同(tong)步展放難(nan)題，我們專門加工了(le)放線(xian)(xian)(xian)滑(hua)(hua)車專用掛(gua)板，既方便了(le)導(dao)線(xian)(xian)(xian)放線(xian)(xian)(xian)滑(hua)(hua)車的(de)懸掛(gua)，又確保了(le)緊(jin)線(xian)(xian)(xian)時6根子導(dao)線(xian)(xian)(xian)相對水平，同(tong)時還(huan)能確保導(dao)線(xian)(xian)(xian)牽引板順利安全的(de)通過(guo)放線(xian)(xian)(xian)滑(hua)(hua)車。”青(qing)豫特(te)高壓（青(qing)2標(biao)段(duan)(duan)）項目經理李(li)積(ji)存說道。

自工(gong)(gong)(gong)程(cheng)(cheng)(cheng)(cheng)建設以(yi)來，國網青海省電(dian)力公司始終以(yi)建設新(xin)時代“樣(yang)板工(gong)(gong)(gong)程(cheng)(cheng)(cheng)(cheng)”為(wei)目標(biao)。針對(dui)沼澤(ze)地施(shi)(shi)工(gong)(gong)(gong)這(zhe)一(yi)困(kun)難采用(yong)鋪設鋼(gang)板修(xiu)筑施(shi)(shi)工(gong)(gong)(gong)通道(dao)的方式修(xiu)建25千米(mi)的施(shi)(shi)工(gong)(gong)(gong)通道(dao)，累計投(tou)入鋼(gang)板4000多塊(kuai)，在(zai)加快施(shi)(shi)工(gong)(gong)(gong)進度的同時有效保護了脆弱(ruo)的生態環境。在(zai)工(gong)(gong)(gong)程(cheng)(cheng)(cheng)(cheng)建設中成立臨時黨支部(bu)，結合工(gong)(gong)(gong)程(cheng)(cheng)(cheng)(cheng)建設多次組織形(xing)式多樣(yang)的“黨建+”系列活(huo)動(dong)，充(chong)分(fen)發(fa)揮現場黨員先鋒模范作用(yong)，組織開展“建和(he)諧(xie)管理團隊，創國優(you)精(jing)品工(gong)(gong)(gong)程(cheng)(cheng)(cheng)(cheng)”活(huo)動(dong)和(he)“六賽(sai)一(yi)創”勞(lao)動(dong)競賽(sai)等(deng)活(huo)動(dong)，依托黨建工(gong)(gong)(gong)作的新(xin)成效助推工(gong)(gong)(gong)程(cheng)(cheng)(cheng)(cheng)各項建設工(gong)(gong)(gong)作快速、有序推進。

新冠肺炎(yan)疫(yi)情發(fa)生以來，國(guo)網(wang)青海(hai)省電力公(gong)司(si)堅(jian)決貫(guan)徹落實(shi)國(guo)家電網(wang)有(you)限公(gong)司(si)黨組(zu)提出的(de)“兩手抓、兩不誤、兩促進(jin)(jin)”工(gong)(gong)作(zuo)要(yao)求，精心(xin)組(zu)織(zhi)(zhi)協(xie)調，于2月23日(ri)全(quan)面(mian)復(fu)(fu)工(gong)(gong)建設，發(fa)揮大國(guo)重器的(de)頂(ding)梁柱(zhu)作(zuo)用，在科(ke)學有(you)序復(fu)(fu)工(gong)(gong)復(fu)(fu)產上做示范，在全(quan)力防(fang)控疫(yi)情的(de)同時，堅(jian)持目標不變、任務不減(jian)，精心(xin)組(zu)織(zhi)(zhi)、科(ke)學管理、攻堅(jian)克難，多舉措落實(shi)各(ge)方面(mian)資源(yuan)和(he)要(yao)素配(pei)置，快(kuai)速推進(jin)(jin)特高壓工(gong)(gong)程復(fu)(fu)工(gong)(gong)建設，目前工(gong)(gong)程各(ge)項施(shi)工(gong)(gong)進(jin)(jin)度均處于可(ke)控、受控狀態(tai)。

下一(yi)步，國網青海省電力(li)公司(si)將(jiang)繼續狠抓現(xian)場安(an)全(quan)管控(kong)，嚴格(ge)落實各項安(an)全(quan)、質量保證措施，嚴格(ge)落實各級職責(ze)，認真做(zuo)好(hao)三級自(zi)檢制度，全(quan)力(li)確保青豫特高(gao)壓(ya)工程按期投運。
