Study on Curtain Grouting Construction Technology of Anti-seepage Reinforcement of Toe Plate of Hydropower Station Dam
In view of the problem of the decrease of the anti-seepage performance of the dam toe plate under the influence of the external envi-ronment.By excavating the toe plate foundation of the hydropower station,the toe plate foundation is treated,and the anchor solid can resist external forces to achieve the purpose of reinforcement.The curtain grouting of the dam foundation constructs the seepage reinforcement line of the toe plate,and control the front edge of the dam foundation and both sides of the hydropower station to avoid rock and soil loss.Strengthen the anti-seepage and reinforce the curtain grouting toe plate core,and inject the grouting material into the toe plate core to fill the core holes and cracks to form an effective anti-seepage barrier,so as to meet the quality requirements of grouting construction.
