Solid waste-based phosphate grouting reinforcement material as well as preparation method and application thereof
The invention belongs to the field of disaster prevention and control of tunnel and underground engineering, and relates to a tunnel and underground grouting reinforcement material, in particular to a solid-waste-based phosphate grouting reinforcement material and a preparation method and application thereof. The component A comprises 20-50 parts of red mud, 10-40 parts of a magnesium compound, 10-30 parts of a mineral admixture, 0.5-1.5 parts of a high-temperature-resistant agent, 0.5-3 parts of a retarder, 0.2-0.5 part of a water reducing agent, 0.2-1.2 parts of an acid-base buffer agent, 1-6 parts of a stabilizer and 0.5-1 part of a surfactant; the component B comprises the following components in parts by weight: 30-60 parts of phosphate and 0.3-1.5 parts of a defoaming agent; after the solid-waste-based phosphate grouting reinforcement material prepared from the solid-waste-based phosphate grouting reinforcement material provided by the invention is mixed with water, slurry is good in self-fluidity, good in high-temperature resistance, high in slurry retention rate and high in stone rate, so that the grouting problem of a high-temperature and high-pressure stratum in a harsh water environment is solved.
本发明属于隧道与地下工程灾害防治领域，涉及隧道与地下注浆加固材料，具体涉及一种固废基磷酸盐注浆加固材料及其制备方法与应用。组分A中，赤泥20～50份，镁化物10～40份，矿物掺合料10～30份，耐高温剂0.5～1.5份，缓凝剂0.5～3份，减水剂0.2～0.5份，酸碱缓冲剂0.2～1.2份，稳定剂1～6份，表面活性剂0.5～1份；组分B中，磷酸盐30～60份，消泡剂0.3～1.5份；本发明提供的固废基磷酸盐注浆加固材料制备的固废基磷酸盐注浆加固材料与水拌合后浆体自身流动性好，耐高温性能好，浆液留存率高，结石率高，从而解决高温高压地层严苛水环境下灌浆问题。
