采沙船对河道采沙的影响，随着我国经济的起飞，大规模基础设施建设在启动，以及随后城市化的发展，对砂石资源的需求激增，而将河道采砂石用于建筑用砂具有质优，价廉的优点，因此，一些人自然将目光投入到了河道。起初，各种采沙船蜂拥而上，将河段的河床，滩岸以及生态环境受到破坏，经过合理的规划，科学认证的河道采沙活动，不会影响河道运行的安全。采沙船是如何采沙的？
    河段范围内主要以采用水采方式，以链斗式采沙船为主，链斗式采沙船主要通过铁畚斗进行采沙作业，每只船上配备了多个铁畚斗，像自行车链条的工作原理一样，通过一个钢架围成一圈，由柴油机带动大小齿轮转动，将动力传给铁畚斗，多个铁畚斗便循环作业，将床砂从河床表层挖起，经输送带送至船上进行清洗，清洗过程中的砾石和淤泥直接落入江中，清洗后的砾石由运砂船运到沙场。

   With the development of China's economy, large-scale infrastructure construction and development in the start, then the city, the surge of sand resources demand, and the river gravel extraction for construction sand with high quality, low cost advantages, therefore, some people will naturally look into the river. At first, all kinds of sand mining of river bed will rush on like a swarm of hornets, the beach, and damage to the ecological environment, through reasonable planning, scientific certification river sand mining activities, will not affect the operation of the safety channel. How is the sand mining sand?
   Within the scope of the main river with water recovery, the chain bucket sand mining, chain bucket sand mining mainly through iron bucket of sand mining operations, each ship is equipped with a plurality of iron bucket, like the working principle of bicycle chain, by a steel frame in a circle by diesel engine the size of drive gear to rotate, transmits the power to the iron bucket, a bucket and iron cycle operation, the bed sand from the riverbed surface dug up, the conveyor belt to the ship for cleaning, the cleaning process of gravel and silt directly into the river, after cleaning the gravel sand transport by ship to the battlefield.
