Hydraulic clamping device and application method thereof

The invention provides a hydraulic clamping device and an application method thereof.The hydraulic clamping device comprises a clamp seat, a chuck and a hydraulic control system, the hydraulic control system is fixed to the clamp seat, the chuck is fixed to one end of a piston rod of the hydraulic control system, and stretching and retracting of the piston rod are controlled based on the hydraulic control system; and therefore, the chuck provides clamping and loosening functions. The hydraulic clamping devices are installed in pairs, the hydraulic control system controls the piston rods to stretch out and draw back and drives the chucks connected with the piston rods to clamp and loosen the rubber waterstop, the installation problem of the rubber waterstop is solved, the installation success rate of the rubber waterstop is guaranteed, the construction efficiency is improved, and the construction quality is guaranteed. The whole device is simple in structure, reliable in function, convenient to operate and hig
