[0017] In this embodiment, figure 1 As shown, the bridge includes a pile foundation 9, a bridge pier 10, and a bridge abutment 1. The transition section includes a pavement, a reinforced concrete hollow slab 3, and backfill 2; the pavement is divided into a pavement layer 7, a pavement cushion layer 5, and the original roadbed 8.
[0018] See figure 1 In this embodiment, one end of a reinforced concrete hollow slab 3 with the same width as the width of the roadbed is implanted in the bridge abutment 1 with a fixed steel bar 4, and the reinforced concrete hollow slab 3 at the position of the fixed steel bar 4 is buried under the pavement cushion 5; The other end of the reinforced concrete hollow slab 3 is placed on the end support 11 close to the original embankment 6, so that the reinforced concrete hollow slab 3 is placed obliquely between the bridge abutment 1 and the end support 11 to form a transition section of roadbed. The rigidity of the reinforced concrete hollow slab 3 is...
