Splitting grouting technology and grouting method thereof
The invention provides a splitting grouting technology and a grouting method thereof, and relates to the technical field of splitting grouting. The splitting grouting technology and the grouting method thereof comprise the following steps: S1, vertically drilling a hole in the dam axis of an earth dam by using a slewing drilling machine; S2, adding water and slurry into a stirrer, and conducting stirring to obtain thin slurry and thick slurry; S3, sequentially injecting the thin slurry and the thick slurry into the drill hole for splitting; and S4, injecting the thick slurry to fill the drill hole. The slurry comprises one or more of CW epoxy resin, a high-polymer grouting material, modified urea-formaldehyde resin, emulsified low-heat asphalt and a microbial liquid, the slurry is injected into the drill hole and then dispersed, the slurry is rapidly expanded in a crack, the purpose of rapid filling is achieved, the compressive strength is higher, and the microbial liquid has a good anti-cracking effect in the metabolism process. Calcium carbonate crystals with a gelling effect can be separated out on the surface of the slurry, so that surrounding soil particles are firmly solidified, the bearing capacity of a foundation is greatly improved, and the cement is worthy of being vigorously popularized.
本发明提供一种劈裂注浆技术及其注浆方法，涉及劈裂灌浆技术领域。该一种劈裂注浆技术及其注浆方法，包括以下步骤：S1、使用回转钻机在土坝的坝轴线上垂直钻孔；S2、向搅拌机内加入水和浆料搅拌制得稀浆和浓浆；S3、将稀浆和浓浆依次注入钻孔内进行劈裂；S4、注入浓浆填满钻孔。通过浆料包括CW环氧树脂、高聚性注浆材料、改性脲醛树脂、乳化低热沥青和微生物菌液中的一种或多种，将浆料注入钻孔内进而分散，浆料在裂缝中急剧膨胀，达到快速填充的目的，并且抗压强度更高，微生物菌液在新陈代谢过程中，可以在其自身表面析出具有胶凝作用的碳酸钙晶体，从而将周围土颗粒牢牢固结，地基承载力大幅度提高，值得大力推广。
