Method for installing hydraulic bottom sill

The invention relates to the technical field of hydraulic bottom sill installation, in particular to a hydraulic bottom sill installation method which comprises the steps that bottom plate concrete pouring is conducted, the concrete vibrating mode is judged according to the concrete compactness, a preset dip angle is determined according to the target water storage capacity, and a corresponding pouring mold set is selected according to the preset dip angle to pour a bottom sill prefabricated part. The bottom sill prefabricated parts are mutually meshed and fixed through steel bars, the sealing grooves are subjected to grouting sealing through standard grouting materials, and the grouting density is measured and compared with the standard grouting density to judge whether supplementary grouting is needed or not; according to the method, the inclination angle is preset, the service life of the bottom sill is prolonged, the influence on the bottom sill due to the fact that the dam is out of position along with t
