Cracks will affect the overall strength and stability of the road bridge structure, may lead to a decrease in the structural bearing capacity, and even endanger the safety of the road bridge.

[0003] Filling cracks in roads and bridges with fillers can quickly fill the gaps and defects inside the cracks, preventing the cracks from expanding and deepening. The use of fillers can usually be constructed quickly and easily, and is less expensive than other complex repair methods, reducing maintenance costs and traffic interruption time.

The interior of the main pipe 1 is provided with a lumen 11 along the length direction of the main pipe 1, the lumen 11 is connected with multiple spray pipes 3, and multiple side pipes 31 are fixedly connected to the circumference of the spray pipe 3. The device is placed in the crack of the road bridge, so that the spray pipe 3 is inserted into the deep crack, and the filling material is poured into the lumen 11 of the main pipe 1 through the feed pipe 2. The filling material flows into the crack through the spray pipe 3 and the side pipe 31, and the crack is filled and repaired after the filling material solidifies. The multiple number of spray pipes 3 improves the filling efficiency.

[0027] The spray pipe 3 can be a straight pipe, such as Figure 4 As shown, preferably, the lower end of the spray pipe 3 can also be in a pointed shape, and the internal diameter of the lower end of the spray pipe 3 gradually decreases downward. Since the inner diameter of the bottom of the spray pipe 3 becomes smaller, the filler will generate a certain pressure when passing through the bottom of the spray pipe 3, which helps the filler to overcome the resistance inside the crack and achieve a deeper filling effect.

[0028] like Figure 3 and Figure 5 As shown, the pressurizing assembly 4 is arranged inside the feed pipe 2, and the pressurizing assembly 4 includes an outer cylinder 41 and a push rod 42.
