压力灌浆在预应力锚索加固边坡中的工艺研究

根据昆石高速某边坡地质条件,采用预应力锚索加固方法,设计了锚索长度和分布形式,对锚索灌浆的施工,提出了压力灌浆新工艺,采用土工布制成的止浆袋新技术有效解决了普通止浆效果差的缺陷.边坡加固后效果证明该方法成本低,机械设备投入少,有利于大面积推广.

Study of Pressure Grouting Construction Craft in Prestressed Anchor Cable in Slope Reinforcement

According the geology condition of the slope in Kun-Shi highway,the prestressed anchor cable was applied,and the length and arrangement of the anchor cable were designed.New craft of the pressure grouting was applied to reinforce the anchor cable,which prevents slurry pocket made of geotextile prevented cement mortar from streaming.The result proves that it effectively resolve the defec produced by the ordinary method.The effectiveness proves that the pressure grouting method is low cost with less equipment...
