Abstract：The deep-hole discharge structure is a crucial component of dams,and clogging can lead to difficulties in gate opening and closing,significantly impacting the safe operation of the dam.This paper summarizes the current state of models for calculating gate opening force in clogged conditions,underwater detection,and cleaning technologies for clogging.It identifies the technical challenges in clearing clogs in deep holes and proposes strategies for underwater environment reconstruction,gate opening force calculation,and equipment for deep-hole dredging.The paper also suggests the need for further research in high-precision underwater environment reconstruction,developing numerical models for gate opening force,and creating integrated cleaning robots for various types of cloggings.These efforts aim to enhance the dam's ability to respond to disasters.
