    采沙船河道采砂的起因和發展

    采沙船河道采沙的起因和發展
         二十世紀八十年代中后期,隨著我國經濟的起飛,大規?;A設施建設在啟動,以及隨后城市化的發展,對砂石資源的需求激增,而將河道砂石用于建設用砂具有質優,價廉的特點。因此,一些人直接將目光直接投向了河道。在當初情況下,河道采砂的監管缺位;而從事河道采沙技術要求低,也不需大量資金投入。達成了沿江沿河一些人的發財致富門路之一。如在長江,在二十世紀九十年代初,在將砂開采的暴力驅使下,各種采沙船蜂擁而至,濫采亂挖隨處可見,導致一些河段的河床、灘岸和涉水工程設施以及生態環境受到破壞和損毀,海損事故頻發,長江防洪和通航安全受到極大威脅,同時引發采沙糾紛甚至暴力沖突,影響社會治安穩定,還造成國有資產的大量流失等一系列問題。
       河道采砂的發展,不僅是參與人/船數量的增加,更重要的是采沙設備功率的提升,采沙用船噸位的增加。
       大規模采砂初期,河道采砂使用的是基本是抓斗式,鏈斗式、抽吸式等采沙機械,在市場對砂石的需求和利潤的驅使下,這些設備越來越不能滿足需求,并催生各類采沙機具不斷升級換代,其功率也不斷提升。采沙船只在增加,特別是采沙設備的能力在提升,采沙能力在發展。

    The cause of river channel sand mining large junk and the development
         In mid and late 1980 s, with China's economic take-off, large-scale infrastructure construction at startup, and then the development of urbanization, the surge in demand of sand resources, and will be used sand river sand used in construction is high quality, cheap characteristics. As a result, some people will look directly into the river directly. In the original case, river channel sand mining in the absence of regulation; And engaged in river channel sand mining technical requirements is low, also do not need a lot of money. Reached one of the enrichment of some people along the river along the way. Such as in the Yangtze river, in the early 1990 s, the sand mining of violence, all kinds of mining in large junk, excessive mining dig everywhere disorderly, leading to some of the river bed, frontage and wading engineering facilities as well as ecological environment is damaged and damaged, frequent accidents at sea, the Yangtze river flood control and navigation safety under great threat, sand disputes and even violence at the same time, influence social security, also cause huge loss of state-owned assets, such as a series of problems.
        The development of the channel sand is not only an increase in the number of participants/ship, more important is sand equipment power to ascend, sand with the increase of the tonnage.
        Early sand mining, the river channel sand mining are using basic clamshell, chain bucket, suction type, such as sand mining machinery, the market demand for sand and profit driven by these devices is more and more can't meet the demand, and create all kinds of mining machinery constantly upgrading, its power is also rising. Sand ships on the rise, especially sand equipment's ability in raising, sand ability in development.
