Performance of New Cement-Based Grouting Materials and Its Application in Tunnel Water Inrush Treatment
摘要
Abstract
The choice of grouting material is pivotal in determining the effectiveness of water inrush control during grouting operations.In or-der to overcome the shortcomings of traditional grouting materials in water blocking,a new type of cement-based water-blocking grouting ma-terial has been developed.The time-dependent behavior of viscosity and mechanical characteristics were assessed through laboratory tests.Subsequently,numerical simulations were employed to comparatively analyze the diffusion patterns of the two-fluid slurry composed of the new material and conventional cement-silicate(C-S)grout in dynamic water environments,thereby evaluating the erosion resistance charac-teristics of the new material.Finally,based on the laboratory test results,selection criteria and adjustment criteria for grout were proposed.A field test for water control grouting was conducted in a tunnel section of a hydraulic engineering project.The study results indicate that the material can achieve quick-setting and early-strength effects without shrinkage and possesses stronger anti-erosion characteristics than C-S grout.By utilizing these materials and adhering to the proposed selection and adjustment criteria for on-site grouting operations,positive out-comes can be attained in managing water inrush situations.关键词
