In prior art, the axle body makes after using for a long time, the pontic has more problem, and then pass through the utility model provides a technical scheme overhauls the bridge, consolidate, add the one deck bridge floor on the axle body, and the spacing portion through the axle body side is injectd the position of bridge floor, it is fixed, guarantee the stability of bridge floor, the bridge floor is hollow plate, the bridge floor is inside bears and is qualitative by pulling reinforcing bar net and structure reinforcing bar net, the stability of its bridge floor has been guaranteed, be equipped with the PVC pipe layer in the hollow plate, can regard as internal drainage pipe of bridge and pipeline, under the condition that original people's bridge does not have drainage pipe, expand the function of its drainage, reduce piling up of people's bridge water-feeding.

Furthermore, a plurality of piers are arranged, and the piers are arranged at equal intervals; the PVC pipe layer comprises a plurality of PVC pipes, and equidistant setting between the PVC pipe. The equidistant setting of pier can make the support of bridge floor more stable, and the PVC pipe is equipped with a plurality of and equidistant setting, can strengthen its drainage performance.

Still further, the thickness of bridge floor is greater than the height of spacing portion. The bridge floor is higher than the bridge body can guarantee that the face concrete of bridge floor is thicker, and bridge floor inner structure result of use is better.
