With the rapid development of socialist economy in our country, especially the new construction and reconstruction works of highways, national highways and provincial highways, there is an increasing number of road and rail intersections inevitably encountered in the planning and design of projects, so that we can only choose Cross the railway and under the railway 2 kinds of programs. At present, there are more cross-rail crossing schemes adopted in the highway industry. In practical projects, prestressed prestressed box girders or T-beams are used in overpass of overpass railway, and prefabricated prestressed box girders or T-beams are installed The construction of the focus and difficulties, this article on the beam rack for some simple discussion.
