Application of High pressure Grouting Rammer in High pressure Consolidation Grouting in Tianhuangping

Abstract:

Pressure of reinforcing grouting for the branch pipe of diversion system in Tianhuangping Power Station is 9.0 MPa. Based on such a pressure, tests were made on both of high pressure inflation rammers and mechanical rammers. Through analysis, advantages and disadvantages of both kinds of rammers as well as the scope of application are summed up.
