[0001] The utility model belongs to the technical field of water conservancy tunnel engineering construction, and in particular relates to a tunnel bottom plate anti-skid grooving rapid construction device. Background Art

[0002] In order to give full play to the coordinated development of water conservancy facilities construction and the life safety of operators, the requirements for anti-skid construction of steep slope tunnel bottom plates are high. The traditional anti-skid construction of steep slope tunnel bottom plates uses a single steel bar for grooving, which has low work efficiency and is time-consuming and labor-intensive. At present, the anti-skid construction of steep slope tunnel bottom plates of water conservancy uses threaded steel bars and steel pipes. These technologies are controllable for the construction technology of anti-skid measures for tunnel bottom plates, but they are not very targeted and the construction progress is slow. Therefore, it is necessary to provide a safe and simple anti-skid grooving rapid construction device for tunnel bottom plates. Summary of the invention
