Strong-permeability stratum grouting material in flowing water environment and preparation method thereof
The invention relates to a strong-permeability stratum grouting material in a flowing water environment and a preparation method thereof, and belongs to the field of preparation of flowing water plugging materials. The grouting material comprises a cementing material, an expansion material and a quick-setting material, and the expansion material comprises potassium polyacrylate crystal particles and sodium polyacrylate crystals. The method comprises the following steps of: (1) preparing a cementing material into a groutable fluid; and (2) adding an expansion material into the slurry in the step (1), uniformly stirring, adding a setting accelerator within 30 minutes, and carrying out grouting. The grouting material provided by the invention has the characteristics of adjustable setting time, water swelling of slurry particles, strong groutability, good water gushing leaking stoppage effects, controllable slurry diffusion range, low cost, no toxicity and the like, and is an excellent-performance strong-permeability stratum grouting reinforcement and seepage prevention material in a flowing water environment.
本发明涉及一种动水环境下强渗透地层注浆材料及其制备方法，属于动水封堵材料的制备领域。所述注浆材料包括胶凝材料、膨胀材料、速凝材料，所述的膨胀材料包括聚丙烯酸钾结晶体颗粒及聚丙烯酸钠结晶体；所述方法包括如下步骤：1)将胶凝材料制成可注浆的流体；2)向步骤1)的浆体中加入膨胀材料，搅拌均匀，在30分钟之内加入速凝剂后进行注浆。本发明的注浆材料具有凝固时间可调、浆材颗粒遇水膨胀、可注性强、涌水堵漏效果好、浆液扩散范围可控、费用低、无毒性等特点，是一种性能卓越的动水环境下强渗透地层注浆加固及防渗材料。
