Research and verification on quality control model of conglomerate grouting process in Western Regions

Abstract

Curtain grouting in the Xiyu conglomerate region is a critical component of seepage control systems for water conservancy and hydropower projects in Xinjiang. It is also a key focus for construction management and quality control in such projects within this geological context. Based on an analysis of the permeability characteristics of Xiyu conglomerate and conventional quality control method in grouting construction, this study systematically investigates the correlation among grouting flow rate, grouting pressure, and the permeability coefficient of Xiyu conglomerate under specified slurry density conditions. Through quantitative analysis, a quality control model for the grouting process, characterized by parameters Q(flow rate), P(pressure), q(permeability), and t(time), is established. Furthermore, new quality control parameters for grouting are proposed, offering an innovative approach for quality management in water conservancy projects within Xiyu conglomerate regions. The proposed model was validated through grouting experiments conducted at the Momoke Water Control Project, and the experimental result confirm its applicability and effectiveness.
