UNDERWATER REPAIR SYSTEM FOR CAVITY REGION OF CONCRETE PANEL ROCK-FILL DAM PANEL

WIPO Patent Application WO/2019/192267

A1

An underwater repair system for a cavity region (21) of a concrete panel rock-fill dam panel, comprising a moving platform, a work cabin (1), a pressure drainage apparatus (6), a traction apparatus, and a positioning apparatus (3); the work cabin (1) and the positioning apparatus (3) are arranged on the moving platform, the traction apparatus controlling the movement of the moving platform on the surface of a dam concrete panel (19); the positioning apparatus (3) transmits a detection position; the work cabin (1) is a pressure cabin having an upper closure structure, the work cabin (1) being connected to the pressure drainage apparatus (6), and a drill apparatus (11) and a grouting apparatus (12) being arranged in the work cabin (1); the moving platform moves into the cavity region (21), and the pressure drainage apparatus (6) starts up to drain the water in the work cabin (1), a partially closed waterless space being formed inside the work cabin (1), the drill apparatus (11) drilling the concrete panel (19) at the upper end of the cavity region (21) and the grouting apparatus (12) subsequently implementing grouting to complete the repair. Underwater repair of the cavity region (21) of a concrete panel rock-fill dam panel is implemented by means of the partially closed waterless space inside the work cabin (1) combined with the drilling apparatus (11) and the grouting apparatus (12).
