Description

Technical Field

[0001] The utility model relates to the technical field of ballast retaining steel plates, in particular to a ballast retaining steel plate for a railway bridge. Background Art

[0002] At present, ballast retaining plates are a commonly used facility in railway projects. They are used to protect the gravel roadbed beside the railway tracks and prevent the scattering and loss of ballast.

[0003] The prior art has ballast plates similar to the above, which are made of concrete. However, ballast plates of this material are large in size and high in density, resulting in a large weight of a single ballast plate. This is especially true for multi-line bridges, which greatly increases the secondary constant load of railway bridges and reduces the passing weight of heavy-load railway bridges. Concrete has low impact strength and is prone to aging. During the construction process of line screening, the mechanical arm of the construction equipment is prone to hit the concrete ballast plate, causing partial damage to the ballast plate. Since the ballast plate is made of concrete, it is impossible to carry it manually on the construction site, and construction machinery and equipment must be used. Therefore, once the ballast plate is damaged, the replacement cost is high and the efficiency is low.

[0004] In order to solve this problem, we proposed the need for a railway bridge ballast retaining plate. By researching and developing a ballast retaining plate made of a new material and using steel plates to form the ballast retaining plate, it is not only easy to disassemble when the steel plate is damaged, but also can maintain sufficient strength. This design can improve the overall convenience and durability of the ballast retaining plate. Utility Model Content

[0011] According to the technical solution provided in the embodiment of the present application, the height of the baffle is greater than 2.5m. The baffle is made of stainless steel and has a layer of paint on the outer surface to prevent the ballast from flying out from the top of the ballast baffle due to excessive speed and the ballast baffle being not high enough, causing danger.

[0012] According to the technical solution provided in the embodiment of the present application, the longitudinal cross-section of the rain shelter is semicircular, the radius of the rain shelter is greater than the width of the base plate, the top surface of the rain shelter is arc-shaped, and the rain shelter is painted with a layer of paint to reduce rainwater falling directly on the base plate and the baffle to extend the service life.

[0013] According to the technical solution provided in the embodiment of the present application, the connecting plate is overall in the shape of a prism, and a layer of waterproof glue is applied to the bottom surface of the connecting plate to prevent the bottom surface from being damp for too long and being damaged.
