7月13日，根據(ju)三(san)峽集團公司要求(qiu)，三(san)峽大(da)壩進(jin)入今年蓄水(shui)位最(zui)高(gao)一次的(de)船(chuan)閘(zha)最(zui)大(da)規模“體(ti)檢(jian)(jian)”——停航檢(jian)(jian)修。此(ci)次檢(jian)(jian)修共7天，前3天為南(nan)線檢(jian)(jian)修，后4天為北線檢(jian)(jian)修。
此次停航檢修由葛(ge)洲壩集團(tuan)機電公司通航工程設(she)備安裝(zhuang)處承(cheng)擔(dan)施工任務，將對三峽船閘南(nan)(nan)北兩線1-4閘室和(he)輸水(shui)廊道進(jin)行(xing)檢查(cha)和(he)檢修，對中南(nan)(nan)五啟閉機油箱(xiang)進(jin)行(xing)更(geng)換(huan)。
此(ci)次(ci)停航(hang)檢修時(shi)間短、難度大(da)，同時(shi)進(jin)入(ru)地下輸水(shui)廊道內(nei)，其水(shui)下部(bu)分(fen)管線復(fu)雜(za)，閘室內(nei)部(bu)昏暗，地板濕(shi)滑，落差大(da)，支(zhi)洞較多，行動不便，給承擔此(ci)次(ci)施(shi)工的葛(ge)洲(zhou)壩(ba)人(ren)帶來了很大(da)困難。
為此，該工(gong)(gong)(gong)(gong)程處(chu)精(jing)心(xin)設計，精(jing)心(xin)準備，在進(jin)入(ru)施(shi)工(gong)(gong)(gong)(gong)場地先辦(ban)理(li)工(gong)(gong)(gong)(gong)作票，明確(que)(que)各個施(shi)工(gong)(gong)(gong)(gong)部位(wei)及施(shi)工(gong)(gong)(gong)(gong)內容(rong)，對(dui)施(shi)工(gong)(gong)(gong)(gong)中用(yong)的起重設備、現場用(yong)電做到萬無一失(shi)，并由專(zhuan)人負(fu)責進(jin)出孔洞的施(shi)工(gong)(gong)(gong)(gong)人員的簽名確(que)(que)認，確(que)(que)保(bao)整個施(shi)工(gong)(gong)(gong)(gong)正常進(jin)行。
據悉，此次停航檢修是為(wei)對三峽船閘工程運行(xing)多年(nian)來(lai)施行(xing)的計(ji)劃性“體檢”，以確保整個長江航運通暢。
