所谓小导管注浆加固地层技术，指的就是顺着隧道开挖轮廓线外，并纵向往前倾斜设置注浆管，同时把浆液注入进去以起到止水与超前加固围岩的效果，当然还具有超前管棚预支护效用。
所謂小導管註漿加固地層技術，指的就是順著隧道開挖輪廓線外，併縱嚮往前傾斜設置註漿管，同時把漿液註入進去以起到止水與超前加固圍巖的效果，噹然還具有超前管棚預支護效用。

The so-cal ed smal duct grouting consolidation te-chnology refers to the tunnel excavating followed contour line, and the set ing grouting pipe longitudinal inclined forward, pu-t ing the slurry injection into the water and lead to the ef ect of surrounding rock reinforcement, but also has advanced shed p-ipe support utility.
