Based on such a pressure, tests were made on both of high pressure inflation rammers and mechanical rammers.
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。
5) physical clogging
机械堵塞
1.
The result shows: the main cause of aquifer clogging in this experiment is physical clogging,passed by 40 hours continuous recharging,the decline of the aquifer permeability was evident,the hydraulic conductivity of the upper column(0-10 cm) decreased from 10.
结果表明,回灌水中的悬浮物颗粒充填含水介质空隙引起的机械堵塞为砂柱堵塞的主要原因,砂柱对回灌水具有明显的去除作用,但对回灌水中的有机物、还原性污染物去除作用有限,当回灌水的污染物浓度较高时,地下水将被持续污染。
6) manipulator bridge
机械手桥架
