Composite karst stratum grouting and water plugging reinforcement material as well as preparation method and application thereof
The invention relates to a composite karst stratum grouting and water plugging reinforcement material and a preparation method and application thereof, and belongs to the technical field of grouting materials. The material comprises the following components in parts by weight: 53-68 parts of coal gangue, 15-20 parts of cement, 0-10 parts of clay, 1-2 parts of bentonite and 4-6 parts of an alkaline activator. According to the preparation method, mixed slurry and the alkaline exciting agent are injected through a double-liquid grouting technology, so that the mixed slurry and the alkaline exciting agent are mixed at a grouting hole. The coal gangue is used as a main material, and a small amount of cement, clay and bentonite are used as auxiliary materials. The plugging agent has the advantages of being good in volume stability, low in manufacturing and using cost, easy to prepare, capable of being pumped for a long distance, capable of effectively plugging a grouting area and the like.
本发明涉及一种复合岩溶地层注浆堵水加固材料及制备方法和应用，属于注浆材料技术领域。材料包括如下重量份的组分：煤矸石53～68份、水泥15～20份、黏土0～10份、膨润土1～2份和4～6份碱性激发剂。制备方法中，通过双液注浆技术分别注入混合浆料和碱性激发剂，使混合浆料和碱性激发剂在注浆孔口混合。本发明以煤矸石为主、少量水泥及粘土、膨润土为辅。具有体积安定性好、制造及使用成本低，易于制备可以进行长距离泵送，从而实现对注浆区域的有效封堵等优点。
