注浆是人工用机械的方法,将浆液压入地层中驱逐地下水,并在孔隙或裂隙中流动,扩散、凝胶、最后形成固体堵水帷幕的过程。所以,要获得良好的注浆效果,其一应掌握受注地层的地质和水文地质,摸清地下水的运动规律;其二了解浆液特性,并研究浆液在地层中流动扩散规律,前者是地下水动力学研究的内容,后者是正在形成的注浆理论。
Grouting is a man-made mechanical method that presses the slurry into the formation to expel ground water and to flow, diffuse, and gel in pores or crevices, and finally form a solid plugging curtain. Therefore, to obtain a good grouting effect, one should grasp the geology and hydrogeology of the stratum affected by the stratum and find out the regularity of the groundwater movement. The other is to understand the characteristics of the stratum and to study the flow and dispersion of the stratum in the stratum. The former is the groundwater hydrodynamics The content of the study, the latter is the emerging grouting theory.
