Background In the long-term service process of the bridge, various cracks are easy to generate on the lower structure, particularly on the bottom surface of the beam bottom plate, the bottom surface of the capping beam and the like due to the actions of bearing load, shrinkage and creep, environmental corrosion and the like. These cracks not only affect the durability of the structure, accelerate the corrosion of the reinforcing steel bars, but also endanger the overall bearing safety of the bridge when serious. Traditional crack repair mainly relies on manual work to set up the scaffold frame and carries out high altitude construction, has inefficiency, security risk height, quality uniformity subalternation drawback. Therefore, development of automatic and intelligent bridge lower crack repairing technology and equipment has become an urgent need in the field of intelligent operation and maintenance of infrastructure. However, achieving high quality automated repair of sub-bridge cracks faces a unique and troublesome set of technical challenges. Firstly, when grouting repair is carried out on cracks on the bottom surface of the bridge bottom, slurry needs to be poured from bottom to top against gravity, air in the cracks is accumulated at the highest point due to natural floating, the air is difficult to discharge through a conventional grouting port, a cavity is easy to form, and filling is not practical. Secondly, in order to prevent the slurry from dripping under the action of gravity, a reliable temporary closure must be applied outside the crack, while achieving a fast, adapted seal on the large-span, rugged bridge bottom surface is extremely difficult. More complex, the grouting process brings the following problems that a grouting pipe needs to pass through a temporary plugging and is communicated with a crack, namely, a grouting hole needs to be formed in a temporarily arranged plugging plate, if a pipeline is directly pulled out after grouting is completed, slurry in the crack can leak through the grouting hole to damage the sealing property, if the pipeline is reserved, a grouting channel and the grouting hole cannot be flushed, residual slurry is solidified in the complex flow channel, the plugging and scrapping of a grouting pore canal and plugging components are caused, and the reusability and the economical efficiency of equipment are seriously affected.
