河湖底淤泥已日益影响到河湖防洪、排涝、灌溉、供水、通航等各项工作的开展，为了进行清淤疏浚，我国每年都开展大规模的河道湖泊疏浚淤泥工程，从而产生数亿万方的疏浚淤泥。目前河道清淤工程中常见的方法利用疏浚船以绞吸式、耙吸式、水力冲挖等方法进行疏浚。
River and lake bottom sludge has increasingly affected the development of river and Lake flood control, drainage, irrigation, water supply, navigation and other work. In order to carry out dredging, China carries out large-scale river and lake dredging sludge engineering every year, resulting in hundreds of millions of cubic meters of dredged sludge. At present, the common methods in river dredging engineering use dredging ships to dredge by means of cutter suction, rake suction, hydraulic scouring and excavation and so on.
这种疏浚方式产生的疏浚泥含水量高达液限的3-5倍，甚至更高，呈流动性状态，易在运输过程中漏洒，对环境造成污染。为了避免对环境造成污染，采用密封的罐车将淤泥输送至堆放点，导致运输的价格大幅上升。同时疏浚淤泥的高含水量需要大容量的容器进行堆放，即占用大的堆场面积。
The water content of dredged mud produced by this dredging method is up to 3-5 times or even higher than the liquid limit. It is in a state of fluidity and is easy to leak during transportation, causing pollution to the environment. In order to avoid environmental pollution, sealed tankers are used to transport the sludge to the stacking point, resulting in a sharp rise in the price of transportation. At the same time, the high water content of dredged sludge requires large capacity containers to be stacked, that is, it occupies a large storage yard area.
