Application of Grouting Method in Maintenance of Road Bridge and Tunnel

Bridges and tunnels are important parts of traffic infrastructure. With the continuous progress of construction, the emergence of new technologies, new processes and new equipment has effectively improved the construction quality of road bridges and tunnels. In the maintenance of bridges and tunnels, grouting method is one of the most commonly used methods, and the actual application has obvious maintenance effect. For various quality problems of roads and bridges, affected by geological, hydrological, traffic flow and other factors, maintenance and repair also need to be strengthened in construction and operation. Combined with the grouting method, this paper analyzes the specific application in the maintenance of road bridge and tunnel. The specific application should be combined with the actual situation of the pavement, analyze the specific application in public maintenance, and further improve the quality of road and bridge engineering.
