Experiment Research On The Pressurized Liquefied Sediment Transport Technology Apply In The "Turbid Water Hydraulic Separation Device"

"Turbid water hydraulic separation device" (referred to as "the device") is a new type of water and sediment separation device. Because the "device" is suffering high restriction in the practical application, this paper will apply pressurized and liquefied sediment transport technology in the "device", Not only solving the high problem about "the device", But also solving the bottom of sedimentation problem about the "device".In this paper, by changing cone slope means of the "device" in order to reduce the height of the "device", At the same time we will lay the seepage piping in cone bottom of the "device", liquefy and export the sediments of bottom by the technology. By physical model test in the laboratory, we will research the cone diameter slope of the "device" and the seepage piping in cone bottom of the "device", and find layout of the seepage piping in cone bottom of the "device". Finally we determine cone slope means of the "device", cone slope means of the "device" is set 1:6 and layout of the seepage piping in cone bottom of the "device" is set the radial pattern. So that cone height of the "device" reduction of 83.4%, analysis of numerical fitting the experimental data are analyzed, we conclude the empirical formula of outflow capacity of water of the "device". The method provide a scientific basis for the application, the scientific basis is pressurized liquefied sediment transport technology in the "device".
