Analyses of Shot Velocity Property of Wet Shotcrete

Abstract:

In view of development of national economy and environmental protection, necessity of researching wet shotcrete technology is discussed in this paper based on rebound reduction, dust reduction and construction quality of wet shotcrete. Jet regular pattern of wet shotcrete is analyzed based on hydrodynamic theory. And calculating method of optimum shot velocity is got.

Key words:wet shotcrete,dust,rebound,diffusion jet,optimum shot velocity,
