水下管(guan)(guan)道(dao)疏通是(shi)指對管(guan)(guan)道(dao)進行疏通，管(guan)(guan)道(dao)中污泥等(deng)廢棄物，保持(chi)長期暢通，防止城市內澇。管(guan)(guan)道(dao)不定期清(qing)淤會造(zao)成污水流動，污染，給人們(men)生活帶來麻煩。  

絞車(che)清(qing)(qing)淤(yu)是利竹子(zi)穿通(tong)需要清(qing)(qing)通(tong)管道(dao)(dao)，然后利管道(dao)(dao)兩(liang)端(duan)檢(jian)(jian)查井(jing)上絞車(che)往復絞動鋼絲繩，成都管道(dao)(dao)疏(shu)通(tong)使淤(yu)積物被清(qing)(qing)通(tong)工具推入下游檢(jian)(jian)查井(jing)中，有(you)手動，電機，電動絞車(che)，清(qing)(qing)通(tong)工具也有(you)很多種，根據不同管大小和戶(hu)需求選擇。管道(dao)(dao)清(qing)(qing)淤(yu)廠(chang)家該(gai)適于管不同管道(dao)(dao)，更適于嚴(yan)重淤(yu)積管道(dao)(dao)。絞車(che)清(qing)(qing)淤(yu)缺點(dian)是將(jiang)竹片(pian)從一個井(jing)送到另一個井(jing)，必須手工完成。管道(dao)(dao)疏(shu)通(tong)工作惡劣(lie)易引起不便(bian)，容易造(zao)成事故(gu)。 

管(guan)(guan)(guan)道清(qing)淤(yu)廠(chang)家通(tong)(tong)溝機(ji)于(yu)同管(guan)(guan)(guan)道之(zhi)間為剛性密封清(qing)淤(yu)器(qi)，在空氣或壓力作為射流通(tong)(tong)過管(guan)(guan)(guan)道，管(guan)(guan)(guan)道內異物，這(zhe)種需(xu)要光滑(hua)管(guan)(guan)(guan)壁規則，淤(yu)積物不能太多(duo)，多(duo)于(yu)核能及(ji)工業金屬排(pai)污(wu)管(guan)(guan)(guan)道清(qing)淤(yu)中。類似(si)一種氣動式通(tong)(tong)溝機(ji)，借(jie)助壓縮空氣把清(qing)淤(yu)器(qi)從一個(ge)檢(jian)查井送到(dao)另一個(ge)檢(jian)查井后，由絞車(che)拉動其尾部鋼絲繩，使翼片張(zhang)開，淤(yu)積物隨(sui)清(qing)淤(yu)器(qi)被刮管(guan)(guan)(guan)道。  

以上兩種機械設(she)備(bei)現很(hen)少見，基本上已經退(tui)歷史舞(wu)臺!現在科學與時俱進與行(xing)業日積月累，機械設(she)備(bei)與成熟，擁有更、更實、更快捷有效施(shi)工工藝。
