Drilling and irrigation construction method for toe board curtain of hydropower station

The invention belongs to the technical field of toe board curtain drilling and grouting construction, and particularly relates to a hydropower station toe board curtain drilling and grouting construction method which comprises the following steps: S1, determining a hole position: firstly, determining the position of a grouting hole in a hydropower station toe board; the drilling and grouting construction method for the toe board curtain of the hydropower station has the advantages that the temperature difference between the cement grout and the grout grouting position environment is reduced, so that the temperature difference stress of the cement grout is reduced, cracking and damage of the cement grout structure are avoided as much as possible, and the fluidity and hydration uniformity of the cement grout can be improved; the hydropower station toe board curtain drilling and grouting construction method further has the functions of cement grout pre-vibrating and insufficient grouting pressure reminding, the
