The construction sequence is: the excavators carry the tones from raw material dump to construction area, and then throw the first filling equably in homework range with excavators.
Fig1 The relationship of blow count and Fig2 The relationship of blow count and depth of fifth point depth of eighth point Conclusion 1) Experiments proved that the determinated riprapping program according to the practical situation is successful. 2) The project adopts the riprapping method, the filling material composition in construction and construction method play a critical role in the riprapping effect.
In the filling material composition, the filling stone diameter should be limited in 500mm and the stone contains less clayey soil and construction waste as far as possible; in the construction method, we must use the riprapping method strictly and can not use the push filling method. 3) The riprapping method applies to the layer with small silt area and small thickness, but in the engineer practice it also used in the larger area and big thickness silt layer.

The grinding wheel manufacturer specifies the characteristic values (bounding type, grain size, grain material, hardness, etc.) which are only general information and do not represent the actual state of the grinding wheel during the process.
Acoustic Emission on Grinding When a material is deformed by some kind of external stimulus, as occurs on grinding operations (contact and friction between grits and workpiece) the lattice structure of the material is distorted and rearranged.
