Research on Flood Control Mechanical Technology with Larger Geocontainers
This paper introduced a new mech a nilized wrecking technology with larger geocontainers applied to flood control, and summarized its development process. Dynamics of larger geocontainers declined in water was dealt with and their stability against scouring and friction was analyzed as well, which provided a theoretical basis for the material selection, structure design and manufacture of geocontainers. A larger geocontainer under itself load can be tightly attached to riverbed so that it is suitable for filling up washout pits in a river and can replace such traditional wrecking methods as cages with stone, willows pillow, jackstone and large netting cage to stabilize dam foot, which is very beneficial to river protection and dam urgency. We developed larger geocontainers with volume from 10 to 12m3, with the aid of dump trucks, excavators, bulldozers and loaders to carry out mechanical stuff, transport, jackstone, and it takes only ten minutes to finish the stuff work. This new technology was applied in the test of Caiji 54th and Wangan 14th dam of Lankao County in the Lower Yellow River in 2004, producing a good result. This technology provides a new way for flood control in the area short of rocks and possesses high value in application and popularization.
