Background With the development of Chinese economy, the flood control engineering system of China has achieved a series of great achievements after construction for years, the dyke break event is obviously reduced, and the flood control level is obviously improved. The flood control engineering system of the dam is an important research content in China. In the emergency process, huge manpower and material resources are consumed in the emergency process because large-scale mechanical equipment cannot enter, and when the breach is plugged, the stone propulsion breach is required to be plugged when the gabion mesh is filled with stones. In the process, large-scale forklift, bulldozer and other equipment cannot enter the rescue and relief sites, and can only rely on a large amount of combined force of liberation force to push the gabion mesh to the position of the crumple, but the pushing process has a plurality of problems, namely, the manual pushing process has too small force, and a plurality of people have to push the gabion mesh in a coordinated manner; secondly, the factor of safety of medium-and small-sized dam is not high, the distance between the requirement of pushing the gabion mesh at the breach and the breach must be close enough to complete the expected effect, but the life safety of the person pushing the gabion mesh in the pushing process is greatly threatened, because the breach is possibly subjected to secondary dike breach at any time, the mode of pushing the gabion mesh into the breach is too low in efficiency, and the risk is large and is not suitable for wide application. Under the background, a novel method and a pushing device suitable for the dike-breach rescue of a medium-small dam are needed to be researched.
