Research on the Grout Diffusion Law in Karst Fissure Media for Protecting Ordovician Limestone Groundwater Environment

Abstract

Researching the internal features of the grouted media, fully understanding the property of the grouting material, comprehensively considering the concrete engineering geological situation have important significance for selection of grouting technology, arrangement of grouting equipment and design of grouting operation. In this paper, the factors influencing the flow law of the grout, including property of the grout, karst fissure features, and grouting technology, were provided. And the grout diffusion law in karst fissure media was analyzed to achieve the optimal grouting effect to protect Ordovician limestone groundwater environment.
