絞(jiao)(jiao)吸式抽(chou)沙(sha)(sha)船是一種(zhong)(zhong)依(yi)靠鉸刀對(dui)河床進行(xing)切(qie)割(ge)、破碎，然(ran)后通過抽(chou)沙(sha)(sha)泵(beng)對(dui)河沙(sha)(sha)進行(xing)抽(chou)取(qu)的一種(zhong)(zhong)采沙(sha)(sha)設備。絞(jiao)(jiao)吸式抽(chou)沙(sha)(sha)船的用(yong)(yong)(yong)途廣泛(fan)，可以(yi)在江河湖海中(zhong)進行(xing)作業。絞(jiao)(jiao)吸式抽(chou)沙(sha)(sha)船除(chu)用(yong)(yong)(yong)河沙(sha)(sha)的抽(chou)取(qu)之外(wai)，還(huan)可以(yi)用(yong)(yong)(yong)于航(hang)道清淤(yu)，航(hang)道挖掘(jue)，吹填造地(di)(di)等(deng)等(deng)。在特殊情況下(xia)絞(jiao)(jiao)吸式挖泥船上安裝大功率絞(jiao)(jiao)刀設備，不(bu)需爆破即可挖掘(jue)玄(xuan)武巖(yan)和(he)石灰石等(deng)巖(yan)石地(di)(di)層。

      絞吸(xi)式抽(chou)沙(sha)船(chuan)(chuan)的(de)(de)工(gong)作效率高(gao)，大(da)型的(de)(de)絞吸(xi)式挖泥(ni)船(chuan)(chuan)每小(xiao)時產(chan)量(liang)可達幾千立方(fang)米，大(da)大(da)提高(gao)了河沙(sha)的(de)(de)產(chan)量(liang)。絞吸(xi)式抽(chou)沙(sha)船(chuan)(chuan)的(de)(de)泵(beng)送(song)距離遠，它可以把泥(ni)沙(sha)或碎巖物料依靠強大(da)動力(li)通過泥(ni)泵(beng)和排泥(ni)管線，泵(beng)送(song)出幾千米之外。
      絞吸式抽沙船(chuan)(chuan)(chuan)的(de)(de)操作(zuo)簡單(dan)，易于控制。抽沙船(chuan)(chuan)(chuan)依靠船(chuan)(chuan)(chuan)艉的(de)(de)臺車使鋼樁定(ding)位和前(qian)(qian)進(jin)，利(li)用絞刀(dao)橋梁臂兩(liang)側(ce)橫(heng)移鋼絲(si)繩與連(lian)接固定(ding)于挖槽兩(liang)測的(de)(de)錨，靠鉸(jiao)車牽引，通過左右擺(bai)(bai)動，在(zai)一(yi)定(ding)的(de)(de)控制擺(bai)(bai)角(jiao)下工作(zuo)，將絞刀(dao)或斗輪挖掘后的(de)(de)泥(ni)沙，經過輸(shu)泥(ni)管泵運送到指(zhi)定(ding)地區。抽沙船(chuan)(chuan)(chuan)的(de)(de)前(qian)(qian)進(jin)由兩(liang)根樁交替運動，邁步向(xiang)前(qian)(qian)。
      大型(xing)絞吸式(shi)(shi)抽(chou)(chou)沙(sha)船帶有自(zi)航(hang)系統．調(diao)遣時可(ke)以自(zi)航(hang)到位(wei)。中(zhong)小(xiao)型(xing)抽(chou)(chou)沙(sha)船多(duo)為無自(zi)航(hang)系統，靠拖(tuo)(tuo)船拖(tuo)(tuo)行。中(zhong)小(xiao)型(xing)抽(chou)(chou)沙(sha)船可(ke)設計建造(zao)成組裝式(shi)(shi)，通過陸路運(yun)輸到現場，經組裝后即可(ke)使用。絞吸式(shi)(shi)抽(chou)(chou)沙(sha)船的經濟性(xing)好(hao)。河沙(sha)的挖掘和(he)輸送(song)可(ke)一次性(xing)完(wan)成，不需其它舶船配合、多(duo)次搬運(yun)，相對工程成本較低。

  The cutter suction barge is a kind of sand-collecting equipment that relies on reamer to cut and break the riverbed, and then extract the sand by pumping the river. The use of twisted-suction barge is widely used in rivers. In addition to the drainage of the river sand suction barge, can also be used for waterway dredging, waterway excavation, blowing and filling and so on. In special case, the cutter suction dredger installs high-power reamer equipment, and can excavate basalt and limestone rocks without blasting.
