CGJ型绞吸式采金船 Cutter Suction gold ship

绞吸式采金船是目前在疏滩工程中运用较广泛的一种船舶，它是利用吸水管前端围绕吸水管装设旋转绞刀装置，将河底泥沙进行切割和搅动，再经吸泥管将绞起的泥沙物料，借助强大的泵力，输送到泥沙物料堆积场，它的挖泥、运泥、卸泥等工作过程，可以一次连续完成，它是一种效率高、成本较低的采金船，是良好的水下挖掘机械。

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.

通过对江、河、海清淤工程的实践，对绞吸式采金船的特性和存在不足有了一定程度的了解，以下将其应用中的体会阐述如下，以供同行们商讨。

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 绞吸式采金船具有良好的参数

1. Cutter-suction gold dredger has outstanding parameters.

（1）绞吸式采金船用途广泛，可以在江河湖海中作业，用以清淤，航道挖掘，吹填造地。在特殊情况下绞吸式采金船上安装大功率绞刀设备，不需爆破即可挖掘玄武岩和石灰石等岩石地层。

(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）绞吸式采金船工作效率高，产量大，泵距远。大型的绞吸式采金船每小时流量可达几千立方米；把泥沙或碎岩物料依靠强大动力通过泥泵和排泥管线，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）绞吸式采金船操作简单，易于控制。采金船依靠船艉的台车使钢桩定位和步进，利用绞刀臂架两测钢缆与固定于挖槽两测的锚，靠铰车牵引，两厢摆动绞切泥沙物料，在一定的控制摆角下工作，将绞动的物料，经过输泥管泵到堆积场。采金船的步进是由两根桩交替运动，迈步向前。

(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）大型绞吸式采金船带有自航系统．迁移时可以自航到位。中小型采金船多为无自航系统，靠拖船拖行。中小型采金船可设计建造成组装式，通过陆路运输到现场，经组装后即可使用。

(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）绞吸式采金船经济性好。物料的挖掘和输送一次性完成，不需要其它舶船配合，几次搬运。相对工程成本较低。

(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.
