管(guan)道(dao)(dao)(dao)清淤是(shi)(shi)(shi)將(jiang)管(guan)道(dao)(dao)(dao)進行(xing)疏通，清理(li)管(guan)道(dao)(dao)(dao)里面的(de)(de)淤泥，保持長(chang)期(qi)暢通，以防止城市發生內澇。我們走(zou)在(zai)街道(dao)(dao)(dao)上都會看到各種下水(shui)(shui)道(dao)(dao)(dao)井(jing)蓋(gai)(gai)，很多都是(shi)(shi)(shi)污水(shui)(shui)井(jing)蓋(gai)(gai)，下雨(yu)天(tian)供城市街道(dao)(dao)(dao)排水(shui)(shui)用的(de)(de)，但是(shi)(shi)(shi)一旦(dan)下水(shui)(shui)道(dao)(dao)(dao)堵(du)塞就會造成(cheng)積水(shui)(shui)，所以管(guan)道(dao)(dao)(dao)清淤是(shi)(shi)(shi)市政建設中(zhong)很重要的(de)(de)一個環節(jie)，那么在(zai)進行(xing)管(guan)道(dao)(dao)(dao)清淤的(de)(de)時候(hou)有哪些訣竅和(he)方法呢(ni)？

絞車清淤技術

絞(jiao)車(che)清(qing)(qing)淤技(ji)術(shu)也(ye)稱作(zuo)機械清(qing)(qing)淤技(ji)術(shu)，這(zhe)是常用(yong)(yong)的一種(zhong)(zhong)(zhong)(zhong)清(qing)(qing)淤技(ji)術(shu)。這(zhe)種(zhong)(zhong)(zhong)(zhong)技(ji)術(shu)使(shi)用(yong)(yong)TT片穿過需(xu)要(yao)清(qing)(qing)淤的管(guan)道(dao)段(duan)，TT 片兩端都系(xi)上鋼(gang)絲繩(sheng)(sheng)，在(zai)清(qing)(qing)淤管(guan)段(duan)的兩端檢(jian)(jian)查井(jing)(jing)上各(ge)設(she)1臺絞(jiao)車(che)，兩根(gen)(gen)鋼(gang)絲繩(sheng)(sheng)上另(ling)一端都系(xi)在(zai)絞(jiao)車(che)上，利用(yong)(yong)絞(jiao)車(che)來(lai)回往復絞(jiao)動(dong)鋼(gang)絲繩(sheng)(sheng)，帶(dai)(dai)動(dong)TT片將淤泥刮到下(xia)游檢(jian)(jian)查井(jing)(jing)內，從(cong)而使(shi)管(guan)道(dao)得到的清(qing)(qing)通。絞(jiao)車(che)的動(dong)力(li)可以是靠人力(li)手動(dong)，也(ye)可以是機動(dong)，這(zhe)要(yao)根(gen)(gen)據實際情況(kuang)而定。絞(jiao)車(che)清(qing)(qing)淤技(ji)術(shu)適用(yong)(yong)于各(ge)種(zhong)(zhong)(zhong)(zhong)直徑的下(xia)水(shui)管(guan)道(dao)，特別是對管(guan)道(dao)淤塞比(bi)較嚴重、淤泥己粘結密實，用(yong)(yong)水(shui)力(li)清(qing)(qing)通效(xiao)果(guo)不(bu)(bu)好時(shi)(shi)，采取這(zhe)種(zhong)(zhong)(zhong)(zhong)方(fang)法效(xiao)果(guo)很好。但(dan)這(zhe)種(zhong)(zhong)(zhong)(zhong)方(fang)法不(bu)(bu)足(zu)點(dian)是，從(cong)一個(ge)(ge)井(jing)(jing)口向另(ling)一個(ge)(ge)井(jing)(jing)口送TT片需(xu)要(yao)人工(gong)(gong)下(xia)井(jing)(jing)完成，如井(jing)(jing)下(xia)工(gong)(gong)作(zuo)條件惡劣，工(gong)(gong)作(zuo)環境不(bu)(bu)佳時(shi)(shi)會給工(gong)(gong)人工(gong)(gong)作(zuo)帶(dai)(dai)來(lai)極大的不(bu)(bu)便甚至可能引發(fa)事故，所以一定要(yao)倍(bei)加注意(yi)安(an)全。至于清(qing)(qing)淤的工(gong)(gong)具(ju)，其種(zhong)(zhong)(zhong)(zhong)類繁多(duo)，可根(gen)(gen)據實際情況(kuang)選(xuan)用(yong)(yong)。這(zhe)是一種(zhong)(zhong)(zhong)(zhong)老式清(qing)(qing)淤方(fang)法，雖然具(ju)有一定的歷史年限，但(dan)是目前也(ye)比(bi)較常用(yong)(yong)。

水沖刷清淤法

水(shui)(shui)沖刷清淤一(yi)般通過(guo)能擋水(shui)(shui)設備(例如：氣(qi)囊)把管道(dao)中(zhong)的污水(shui)(shui)阻(zu)擋在其裝(zhuang)(zhuang)置(zhi)的上游(you)，為水(shui)(shui)位達到一(yi)定高(gao)度后(hou)便放(fang)水(shui)(shui)，使上游(you)水(shui)(shui)形(xing)成水(shui)(shui)流來清除管道(dao)內的沉積(ji)(ji)物。沉積(ji)(ji)物沖走后(hou)，這個裝(zhuang)(zhuang)置(zhi)就向(xiang)下游(you)移(yi)動一(yi)段位置(zhi)，再進行(xing)集水(shui)(shui)清淤。這種(zhong)技術效率不高(gao)，所以，應用(yong)不廣泛。
