Grouting material for karst pipeline flowing water plugging, preparation method and application
The invention relates to a grouting material for karst pipeline flowing water plugging, a preparation method and application. The grouting material for karst pipeline flowing water plugging comprisesthe following specific components by mass: 37-64 parts of light calcined magnesia, 24-60 parts of potassium dihydrogen phosphate, 0-30 parts of fly ash, 4-6 parts of bentonite, 95-105 parts of water,0-3 parts of water glass, 0.1-0.2 part of hydroxypropyl methyl cellulose, 2-5 parts of borax, and 0-0.4 part of polypropylamide. The water plugging filling material disclosed by the invention is shortin solidification and hardening time and high in interface adhesive force, and meets the sealing requirement of a large-flow karst pipeline.
本发明涉及一种用于岩溶管道动水封堵的注浆材料、制备方法及应用，所述用于岩溶管道的堵水填充材料的具体组分及质量配比为：轻烧氧化镁37‑64份、磷酸二氢钾24‑60份、粉煤灰0‑30份、膨润土4‑6份、水95‑105份、水玻璃0‑3份，羟丙基甲基纤维素0.1‑0.2份，硼砂2‑5份,聚丙基酰胺0‑0.4份，本发明的堵水填充材料凝固和硬化时间短，界面附着力高，满足了大流量岩溶管道的封闭需求。
