Prefabricated railway simply-supported T-beam structure provided with sound barrier

The utility model provides a prefabricated assembly type railway simply-supported T beam structure with a sound barrier, which relates to the technical field of bridges, and comprises a prefabricated block and a stiffening rib with a bracket, the prefabricated block comprises a ballast blocking wall close to the flange of a prefabricated T beam, a cable trough positioned on the upper surface of the prefabricated block and a sound barrier upright post embedded part, the cable trough is located between the ballast blocking wall and the sound barrier stand column embedded part. The stiffening rib with the bracket is connected with the prefabricated T-beam, and the upper plane of the stiffening rib with the bracket is connected with the prefabricated block. Prefabricated assembly type construction is adopted, green building is achieved, the cast-in-place construction workload is reduced, the construction quality is improved, the later maintenance work is reduced, and the durability of the structure is improved. 本
