江(jiang)蘇南排市政(zheng)建設有限公司 該(gai)工(gong)程運用CCTV管(guan)(guan)(guan)道(dao)內(nei)窺電(dian)視(shi)檢測(ce)(ce)系統(tong)(tong)這一現(xian)代技術(shu)，對管(guan)(guan)(guan)道(dao)內(nei)的(de)(de)銹層、結垢、腐蝕(shi)、穿孔、裂紋等(deng)狀(zhuang)況進(jin)行(xing)探測(ce)(ce)攝像，并記錄管(guan)(guan)(guan)道(dao)內(nei)部狀(zhuang)況，將地下(xia)隱蔽管(guan)(guan)(guan)線(xian)變為(wei)電(dian)腦上清晰可(ke)見的(de)(de)管(guan)(guan)(guan)內(nei)狀(zhuang)況錄像，作(zuo)業人員由此(ci)制定相(xiang)應的(de)(de)污水管(guan)(guan)(guan)道(dao)清淤檢測(ce)(ce)修(xiu)(xiu)(xiu)復方案，大(da)大(da)減(jian)少周折提升效率。在涉(she)及城區管(guan)(guan)(guan)道(dao)的(de)(de)修(xiu)(xiu)(xiu)復中，大(da)多采(cai)用非開挖修(xiu)(xiu)(xiu)復新技術(shu)，在不破損所涉(she)道(dao)路的(de)(de)情況下(xia)，通過局(ju)部樹脂固化(hua)、短(duan)管(guan)(guan)(guan)置換、紫外光固化(hua)修(xiu)(xiu)(xiu)復等(deng)方式，進(jin)行(xing)管(guan)(guan)(guan)道(dao)內(nei)部修(xiu)(xiu)(xiu)復，相(xiang)比傳統(tong)(tong)管(guan)(guan)(guan)道(dao)修(xiu)(xiu)(xiu)復方式，更科學更便捷，施工(gong)周期縮短(duan)，對環境(jing)影響也較小(xiao)。

南(nan)排(pai)市(shi)(shi)政(zheng)(zheng)為(wei)確(que)保工(gong)程項(xiang)目高(gao)效(xiao)有序(xu)推進(jin)，南(nan)京市(shi)(shi)水(shui)務(wu)集團堅持統籌協(xie)調(diao)，倒排(pai)施(shi)工(gong)工(gong)期(qi)，強化施(shi)工(gong)力量，抓好資金保障，全力排(pai)除障礙。每天投入不少(shao)于(yu)30多(duo)(duo)個施(shi)工(gong)班組、60多(duo)(duo)部施(shi)工(gong)車輛(liang)和190個以(yi)上施(shi)工(gong)人員進(jin)場施(shi)工(gong)作業。截至目前(qian)(qian)，已全部完成186.56公里(li)的管(guan)道(dao)清(qing)淤檢測，更換井(jing)蓋112座(zuo)，開挖(wa)及(ji)提升暗井(jing)89座(zuo)，修復(fu)倒虹管(guan)13條約1457米，開挖(wa)修復(fu)管(guan)道(dao)184米，非(fei)開挖(wa)修復(fu)（紫外光固化）6處(chu)430米，局部樹脂固化698環，修復(fu)井(jing)室9座(zuo)，更換安(an)裝防墜(zhui)網6051座(zuo)，比(bi)原計劃提前(qian)(qian)21天完成任務(wu)。市(shi)(shi)政(zheng)(zheng)污(wu)水(shui)管(guan)道(dao)清(qing)淤檢測修復(fu)工(gong)程提前(qian)(qian)順利完工(gong)，大大提升城鄉污(wu)水(shui)收集輸送能力和污(wu)水(shui)處(chu)理廠進(jin)水(shui)COD濃(nong)度。

此外，該工程還同(tong)步實(shi)(shi)施(shi)管(guan)(guan)網(wang)測繪普查，收集并(bing)(bing)錄入管(guan)(guan)道基礎數據，形成(cheng)全市污水(shui)管(guan)(guan)網(wang)“一(yi)張圖(tu)"，建立和(he)完善排(pai)水(shui)管(guan)(guan)網(wang)GIS地理信息系統，構建并(bing)(bing)落實(shi)(shi)周期(qi)性檢測制(zhi)度和(he)運行(xing)維護長效機制(zhi)。
