摘要
Abstract
The section of Luding Dam on main river bed is 100.54 m length and the suspended cut-off wall with a maximum depth of 110 m is used to control seepage. The curtain grouting in overburden under the cut-off is conducted, in which, the curtain grouting holes penetrate into the bedrock about 10 m and the maximum hole depth is 154.8 m. As the complex structure and strong permeability of overburden, the pore-forming rate is low and the grouting effect is difficult to guarantee. The curtain grouting are summarized herein from drilling control, slurry composition and mix ratio, grouting pressure selection, grouting completion standard and quality inspection.关键词
