Groove wall brushing device for underground foundation construction

The utility model provides a groove wall brushing device for underground foundation construction, which comprises a vertically through box body, a mechanical kinetic energy component for driving is arranged in the box body, and a rotary cleaning component in transmission connection with the mechanical kinetic energy component is arranged on the front side of the box body. The mechanical kinetic energy assembly drives the rotary cleaning assembly to rotate to clean the groove wall, and two vertically-symmetrical magnetic wall scraping plates are further arranged on the front face of the box body and used for adsorbing the device to a steel structure of the groove wall and scraping away impurities. The mechanical kinetic energy assembly is arranged in the penetrating type box body, falling or lifting kinetic energy is converted into rotating kinetic energy, the rotating cleaning assembly is used for wall brushing, the wall brushing effect is enhanced, a power line does not need to be pulled, electric energy doe
