Abstract:Xinjiang Chahanwusu Hydropower Station is the third cascade hydropower station in the upstream of Kaidu River in Xinjiang.It happens that different partial collapses for many times during the process of excavation at right-bank spillway in the hydropower station.Thus consolidation grouting test is done before grouting construction to adjust all kinds of parameters.Based on original on-site test and supplementary grouting test design parameters and construction sequence are introduced.The construction method with supplementary grouting test is more reasonable by analyzing injection amount average water-injection rate unit injection amount and quality check result.As a result construction quality and safety are ensured.
