水(shui)下(xia)管道(dao)(dao)疏通(tong)(tong)是(shi)指對管道(dao)(dao)進行疏通(tong)(tong)，管道(dao)(dao)中污泥等廢(fei)棄(qi)物，保持長期(qi)暢通(tong)(tong)，防止城市內澇。管道(dao)(dao)不定期(qi)清淤(yu)會造成(cheng)污水(shui)流動，污染(ran)，給人們(men)生活帶來麻煩(fan)。  

絞車清(qing)(qing)淤(yu)是(shi)利(li)竹子(zi)穿通(tong)(tong)(tong)需要清(qing)(qing)通(tong)(tong)(tong)管(guan)道(dao)，然后利(li)管(guan)道(dao)兩端(duan)檢查井(jing)(jing)(jing)上絞車往復(fu)絞動(dong)鋼絲繩，成(cheng)(cheng)都管(guan)道(dao)疏(shu)通(tong)(tong)(tong)使淤(yu)積物(wu)被清(qing)(qing)通(tong)(tong)(tong)工(gong)具(ju)推入下游檢查井(jing)(jing)(jing)中(zhong)，有(you)手動(dong)，電機，電動(dong)絞車，清(qing)(qing)通(tong)(tong)(tong)工(gong)具(ju)也有(you)很多(duo)種，根據不同管(guan)大小和戶需求選擇。管(guan)道(dao)清(qing)(qing)淤(yu)廠家(jia)該適于管(guan)不同管(guan)道(dao)，更適于嚴重淤(yu)積管(guan)道(dao)。絞車清(qing)(qing)淤(yu)缺點是(shi)將竹片從一個井(jing)(jing)(jing)送到另一個井(jing)(jing)(jing)，必須手工(gong)完成(cheng)(cheng)。管(guan)道(dao)疏(shu)通(tong)(tong)(tong)工(gong)作(zuo)惡劣易引起不便，容易造成(cheng)(cheng)事故。 

管(guan)道(dao)(dao)(dao)清淤(yu)(yu)(yu)廠(chang)家通溝機于(yu)同管(guan)道(dao)(dao)(dao)之間為剛(gang)性密封清淤(yu)(yu)(yu)器(qi)，在空氣或(huo)壓(ya)力作為射流通過管(guan)道(dao)(dao)(dao)，管(guan)道(dao)(dao)(dao)內異物，這種需(xu)要光滑管(guan)壁規則，淤(yu)(yu)(yu)積(ji)物不能(neng)(neng)太多(duo)，多(duo)于(yu)核(he)能(neng)(neng)及工(gong)業金屬排污管(guan)道(dao)(dao)(dao)清淤(yu)(yu)(yu)中。類似(si)一種氣動式(shi)通溝機，借助(zhu)壓(ya)縮空氣把清淤(yu)(yu)(yu)器(qi)從一個(ge)檢(jian)查(cha)井送到另一個(ge)檢(jian)查(cha)井后，由(you)絞車拉動其尾(wei)部鋼絲(si)繩(sheng)，使翼片張開，淤(yu)(yu)(yu)積(ji)物隨清淤(yu)(yu)(yu)器(qi)被刮管(guan)道(dao)(dao)(dao)。  

以上兩種機(ji)械(xie)設備現很少見，基本上已經退歷史舞臺!現在科學(xue)與時俱進與行業日積月累，機(ji)械(xie)設備與成熟(shu)，擁有(you)更、更實、更快(kuai)捷有(you)效(xiao)施工(gong)工(gong)藝。
