Revolving Jet Nozzle Design on Eliminate Surface Soil of Shallow Submersion
The revolving jet is a technique method of using the water to eliminate shallow submersion land mine surface, it can be also used in the clearance of mine, the unique characteristic is the main use of shear broken, erosion crushing, stretch broken cyclone grinding effect on the topsoil which is on shallow mines. this technology research and the application. Based on the revolving water jet flow theory and soil mechanics theory, by means of the action of the jet flow to the soil body surface and the mechanism of the revolving jet flow breaking ground analysis, and the thoughts of which the action pressure of jetting is basic external factor of the soil body destruction, but the soil body critical destructive power to soil body is determined by its internal factors that physical and mechanical properties of the soil, only then, when the jet flow action is greater than the soil body the critical destructive power, the soil body only then possibly has the destruction. This technology research and the application not only raise efficiency of the mine clearance, but also further expand application scope of the water Jet. Based on water jet test platform of the laboratory, in order to make the revolving jet produce the greatest ground-breaking efficiency. the swirling jet nozzle and rotating components are optimized for it.
