高压灌浆塞在天荒坪高压固结灌浆中的应用

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

摘要:

天荒坪电站引水系统岔管段固结灌浆压力为90MPa,据此对高压充气塞和机械塞2种灌浆塞进行试验分析,总结出各自的优缺点及其适用条件。

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.
