<p>The present invention relates to a three liquid-type grouting material and a grouting method using the same. An objective of the present invention is to provide a three liquid-type grouting material, which has superior water resistance and water-blocking properties through the stable gelation at a low temperature and has semi-permanent water-blocking and superior ground reinforcing properties by minimizing leaching of silicate, and a grouting method using the same. The present invention includes a first injection material consisting of amorphous calcium aluminate, anhydrous gypsum and dehydrate gypsum; a second injection material consisting of cement and a set controlling agent; and a third injection material consisting of silicate No. 3, silica fume, EVA, and sodium hydroxide or calcium hydroxide solution, which are wet-pulverized and mixed. The first injection material is mixed with water in a weight ratio of 1:3 and injected into an injection tube, the second injection material is mixed with water in a weight ratio of 1:1 and mixed with the first injection material in the injection tube, and the third injection material is mixed with water in a weight ratio of 1:1 and mixed with the first and second injection materials at a front end of the injection tube, thereby forming a three liquid-type grouting material which is injected into the ground through a spray hole and a front spray hole of the injection tube.</p> |
