- Abstract
Gallery plays an important role in dam construction, maintenance and operation. The issue of gallery leakage is increasingly attracting attention due to its intricate implications for dam safety and stability. If unaddressed, leakage may pose a risk to the dam’s structural integrity, with potential ramifications on both lives and property. In order to explore the mechanism of leakage disaster and put forward effective treatment strategies, this study took the Banqiao Reservoir as an example and comprehensively analyzed the results of preliminary monitoring, sonar microflow field detection and field crack investigation. The results show that the gallery leakage diseases in the spillway dam section mainly include construction quality defects, inadequate sealing and grouting reinforcement, structural cracking caused by temperature stress and concrete deterioration caused by long-term water seepage. Based on this assessment, after comparing various technical solutions, the non-reactive polymer grouting technology is ultimately selected for the successful remediation of the gallery’s leakage and damage, achieving significant treatment.
