CGJ型絞吸式采金船 Cutter Suction gold ship

絞吸式采金船是目前在疏灘工程中運用較廣泛的一種船舶，它是利用吸水管前端圍繞吸水管裝設旋轉絞刀裝置，將河底泥沙進行切割和攪動，再經吸泥管將絞起的泥沙物料，借助強大的泵力，輸送到泥沙物料堆積場，它的挖泥、運泥、卸泥等工作過程，可以一次連續完成，它是一種效率高、成本較低的采金船，是良好的水下挖掘機械。

As a widely used ship used in dredge engineering at present, cutter-suction dredger cuts and stirs the bottom sediment using the rotating cutter device mounted around suction pipe at the front side, and then conveys the silt materials to silt dumping yard via silt suction pipe making use the powerful pump force. The dredging, conveyance and unloading works can be completed in a continuous way at one time. This dredger is a high-efficiency and cost-efficient underwater excavation machinery.

通過對江、河、海清淤工程的實踐，對絞吸式采金船的特性和存在不足有了一定程度的了解，以下將其應用中的體會闡述如下，以供同行們商討。

From the sediment evacuation engineering practice for rivers and the sea, we have made a certain degree of understanding of properties and shortages of cutter-suction gold dredger. The experience from application is described as follows, for your reference.

1 絞吸式采金船具有良好的參數

1. Cutter-suction gold dredger has outstanding parameters.

（1）絞吸式采金船用途廣泛，可以在江河湖海中作業，用以清淤，航道挖掘，吹填造地。在特殊情況下絞吸式采金船上安裝大功率絞刀設備，不需爆破即可挖掘玄武巖和石灰石等巖石地層。

(1) Cutter-suction gold dredger is widely used for operation in rivers, lakes and the sea, channel excavation and land formation. . In particular cases, the cutter-suction gold dredger provided with large power cutter equipment can excavate at basalt and lime rock strata without blasting operation.

（2）絞吸式采金船工作效率高，產量大，泵距遠。大型的絞吸式采金船每小時流量可達幾千立方米；把泥沙或碎巖物料依靠強大動力通過泥泵和排泥管線，泵送出千米之外。

(2) Cutter-suction gold dredger features high operational efficiency, large output and long pump distance. . The flow per hour of large-scale cutter-suction gold dredger may reach thousands of cubic meters. Relying on the strong power, silt or crushed stones can be conveyed to a place kilometers away through dredge pump and dredging pipeline.

（3）絞吸式采金船操作簡單，易于控制。采金船依靠船艉的臺車使鋼樁定位和步進，利用絞刀臂架兩測鋼纜與固定于挖槽兩測的錨，靠鉸車牽引，兩廂擺動絞切泥沙物料，在一定的控制擺角下工作，將絞動的物料，經過輸泥管泵到堆積場。采金船的步進是由兩根樁交替運動，邁步向前。

(3) Cutter-suction gold dredger features simple operation and is easy to control. . With the trolley at the rear part of gold dredger, the steel pile is positioned and moved. The wing rooms swing and cut the silt material using the wire rope at both sides of cutter arm support and the anchor fixed to both sides of excavation channel through the winch. Through the operation at a certain control angle, the materials are conveyed to dumping site through dredging pipe. . The stepping of gold dredger is realized through alternating movement of the two piles.

（4）大型絞吸式采金船帶有自航系統．遷移時可以自航到位。中小型采金船多為無自航系統，靠拖船拖行。中小型采金船可設計建造成組裝式，通過陸路運輸到現場，經組裝后即可使用。

(4) Large-scale cutter-suction gold dredger is provided with self-propulsion system. . The dredger can move to its position using self propulsion during the movement. . Most medium and small-sized gold dredgers are not equipped with self-propulsion system and thus move under the force of tug boat. However, they can be designed and built in an assembled type. In this way, they can be assembled and put into operation after being transported to the site through land transportation.

（5）絞吸式采金船經濟性好。物料的挖掘和輸送一次性完成，不需要其它舶船配合，幾次搬運。相對工程成本較低。

(5) Cutter-suction gold dredger is economic. . The excavation and conveyance of material is completed with a single pass and needs no cooperation from other dredgers. . Relatively, the engineering cost is low.
