Embodiment Construction
[0033] The present invention will be described in further detail below through specific embodiments in conjunction with the accompanying drawings.
[0034] Considering the complex installation method and difficult maintenance of the existing intercity railway sidewalk structure, this embodiment provides a combination structure and combination method of a simply supported T-beam sidewalk on a passenger-cargo railway line.
[0035] The combined structure includes: embedded parts, steel beams and prefabricated reinforced concrete slabs; among them,
[0036] The embedded parts are placed in the prefabricated ballast retaining wall of the passenger-cargo railway, and the root of the steel beam is fixedly connected with the embedded part; the upper surface of the steel beam is on the same plane as the upper surface of the prefabricated ballast retaining wall; Prefabricated reinforced concrete slabs;
[0037] The prefabricated reinforced concrete slab includes a horizontal branch an...

The invention relates to the technical field of railroad bridge engineering of mixed passenger and freight railways, in particular to a simply supported T beam sidewalk combination structure and a combination method of a mixed passenger and freight railway. The combination structure comprises embedded parts, a steel cross beam and a prefabricated reinforced concrete slab, wherein the embedded parts are arranged in a prefabricated retaining track wall of the mixed passenger and freight railway, and the root portion of the steel cross beam is fixedly connected with the embedded parts. The upper surface of the steel cross beam and the upper surface of the prefabricated retaining track wall are located on the same plane. The prefabricated reinforced concrete slab is arranged on the upper surface of the steel cross beam and comprises a transverse branch and one or more vertical branches, the vertical branches are fixedly connected with the transverse branch and upwards extend from the upper surface of the transverse branch, and extending-out steel bars are outwards reserved at the root portion of the transverse branch. The upper surfaces of the vertical branches are covered with an active powder concrete RPC cover plate. The integrity of the combination structure is improved, convenience is brought to cable laying, steel members and a welding material are both weathering resistant steel, and the work amount of later maintenance or repair is decreased.
Description
technical field [0001] The invention relates to railway technology, in particular to a combination structure and a combination method of a simply supported T-beam sidewalk for a passenger-cargo railway. Background technique [0002] A large part of my country's railway bridges adopt simply supported T-beams, and sidewalks are set on both sides of the bridge deck for railway maintenance personnel to walk. The sidewalk is in the form of steel brackets, which are welded or spliced with angle steel, fixed to the bridge deck ballast wall by pre-embedded U-shaped bolts or pre-embedded T-shaped steel, and reinforced concrete sidewalk steps are laid on the brackets. The construction process is complicated, and the later maintenance and repair workload is heavy. Contents of the invention [0003] The object of the present invention is to provide a combination structure and combination method of simply supported T-beam sidewalks on passenger-cargo railways, so as to solve the pro...
