The invention discloses a cast-in-place reinforced concrete bridge. The cast-in-place reinforced concrete bridge comprises a first concrete layer, a second concrete layer, a supporting layer and a third concrete layer, wherein the first concrete layer is a bottom layer of the bridge; a hollow pipe is arranged in the second concrete layer and penetrates through the vertical direction of the bridge; a steel bar is arranged on the outer wall of the hollow pipe; the supporting layer is arranged in the hollow pipe and is composed of a plurality of honeycomb single edge thin sheets; each honeycomb single edge thin sheet comprises a plurality of grooves and a plurality of connection parts; honeycomb holes are formed between any two grooves by the fixed connection between the bottoms of the grooves; the third concrete layer is used as a top layer of the bridge, is an abrasion layer and is of a thin structure layer formed by paving hard fine particles and binding materials. The cast-in-place reinforced concrete bridge adopts a reinforced concrete structure; three different concrete structures are adopted; the hollow pipe is arranged in one type of concrete and a supporting structure is arranged in the hollow pipe; the bridge adopting the structure has the characteristics of good durability, strong pressure resistance, low self gravity and strong bending resistance.
