Experimental Research on Preventing Root-Stones Loss with Tetrahedron-Like Concrete Penetrating Frames

Abstract:

The root-stones loss for flood control project is serious in the Lower Yellow River, and the tetrahedron-like concrete penetrating frame is a new protection technology. The Experiment on preventing root-stones loss of flood diversion and regulation works in Taohuayu with tetrahedron-like concrete penetrating frames in the Xingyang reach of the Yellow River. The experiment results show that: (1) the technology of tetrahedron-like concrete penetrating frame is simple, and it can make root-stones very steady; (2) the tetrahedron-like concrete penetrating frame can effectively reduce the depth of scour holes in front of dam and slow the direct impact of water flow on the dam body; (3) the tetrahedron-like concrete penetrating frame can effectively reduce root-stones loss and save lots of stones; (4) the tetrahedron-like concrete penetrating frames could be made use of for the project foundation stabilization, and they are thrown into the slope of root-stones and the riverbed outside slope toe within a certain width to increase the effect of root-stones protection better.
