Bag grouting plugging method for large-size leakage channel under flowing water condition
The invention provides a bag grouting plugging method for a large-size leakage channel under the flowing water condition, and belongs to the technical field of karst high-speed flowing water plugging of refuse landfills. The method comprises the following steps: acquiring parameters of a seepage channel, quickly plugging a large-size flowing water seepage channel by utilizing bag grouting, and plugging a front gap and a rear gap between a bag plugging object and the seepage channel by utilizing secondary grouting. According to the method, the geometrical characteristics of a leakage channel are detected, the shape of a bag is designed, the bag and a bag grouting pipe are prepared through environment-friendly degradable materials, the bag is utilized to block the large-size flowing water channel to the maximum extent, then secondary grouting is carried out through a slow flow area formed by the bag, the large-size flowing water channel can be completely blocked, and the anti-seepage requirement is met; the method is simple and easy to implement and high in adaptability, and the grouting plugging anti-seepage problem of the large-size karst leakage channel of the refuse landfill is solved from the technical level.
本发明提供一种动水条件下大尺寸渗漏通道的袋囊注浆封堵方法，属于垃圾填埋场岩溶高速动水封堵技术领域。该方法的步骤包括渗流通道参数的取得，利用袋囊注浆快速封堵大尺寸动水渗漏通道，利用二次注浆封堵袋囊封堵物与渗漏通道前后缝隙。该方法通过探测渗漏通道几何特征，设计袋囊形状，利用环保可降解材料制备袋囊和袋囊注浆管，最大限度的利用袋囊封堵大尺寸动水通道，然后利用袋囊形成的缓流区开展二次注浆，可以达到完全封堵大尺寸动水通道并满足防渗要求，减少污染物的运移和扩散的目的，且简单易行，适用度高，从技术层面上解决了垃圾填埋场大尺寸岩溶渗漏通道的注浆封堵防渗难题。
