     采沙船對(duì)河道采沙的影響，隨著我國(guó)經(jīng)濟(jì)的起飛，大規(guī)模基礎(chǔ)設(shè)施建設(shè)在啟動(dòng)，以及隨后城市化的發(fā)展，對(duì)砂石資源的需求激增，而將河道采砂石用于建筑用砂具有質(zhì)優(yōu)，價(jià)廉的優(yōu)點(diǎn)，因此，一些人自然將目光投入到了河道。起初，各種采沙船蜂擁而上，將河段的河床，灘岸以及生態(tài)環(huán)境受到破壞，經(jīng)過(guò)合理的規(guī)劃，科學(xué)認(rèn)證的河道采沙活動(dòng)，不會(huì)影響河道運(yùn)行的安全。采沙船是如何采沙的？
    河段范圍內(nèi)主要以采用水采方式，以鏈斗式采沙船為主，鏈斗式采沙船主要通過(guò)鐵畚斗進(jìn)行采沙作業(yè)，每只船上配備了多個(gè)鐵畚斗，像自行車鏈條的工作原理一樣，通過(guò)一個(gè)鋼架圍成一圈，由柴油機(jī)帶動(dòng)大小齒輪轉(zhuǎn)動(dòng)，將動(dòng)力傳給鐵畚斗，多個(gè)鐵畚斗便循環(huán)作業(yè)，將床砂從河床表層挖起，經(jīng)輸送帶送至船上進(jìn)行清洗，清洗過(guò)程中的礫石和淤泥直接落入江中，清洗后的礫石由運(yùn)砂船運(yùn)到沙場(chǎng)。

   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.
