Description

Novel integral pavement and ballast blocking plate for railway bridge

Technical Field

The utility model relates to a railway bridge technical field specifically is a novel integral pavement of railway bridge keeps off tiny fragments of stone, coal, etc. board concurrently.

Background

The bridge ballast blocking plates are of an L-shaped structure, are laid on the top surfaces of ballast grooves on two sides of a bridge and serve as transverse ballast blocking stress walls of the bridge, and have the functions of preventing a track expanding runway, increasing transverse resistance of a track bed, keeping a line stable and preventing stone ballasts from scattering on a sidewalk. Because the L-shaped ballast retaining wall is not an integral structure but a thin-wall concrete member, the damage and the deterioration are serious. And the ballast blocking plate can only utilize the skylight time, and the skylight time is short, so that the contradiction that the ballast blocking plate is low in regulation efficiency and high in degradation speed is increasingly prominent.

At present, the traditional method for repairing the replacement and pouring of the ballast retaining plate has certain defects, and mainly comprises the following points:

1. the operation time is short: the repair work of replacement and pouring of the L-shaped ballast retaining plates on the bridge needs to disturb the track bed and the track structure and can be carried out only by utilizing the time for repairing the skylight;

2. the difficulty of renovation is large: due to poor operation conditions, the replacement and the renovation operation of the bridge ballast retaining plate bring certain difficulty to the renovation.

3. The treatment efficiency is low: in the skylight operation renovation of the ballast blocking plate site, the operation time is short, the renovation means is backward, and the renovation operation speed is low and the efficiency is low.

Therefore, the novel integral sidewalk and ballast retaining plate for the railway bridge is provided.
