Description

Technical Field

[0001] The utility model relates to the technical field of bridges, in particular to a bridge anti-water accumulation structure. Background Art

[0002] With the development and progress of social economy and engineering technology, landscape bridges and steel structure bridges are increasing in the field of transportation infrastructure construction, and the durability of bridge structures is also receiving more and more attention.

[0003] Landscape bridges have a high probability of forming concave areas where water may accumulate due to their shape requirements, such as the positions of special-shaped arch ribs and the positions of arch-beam joints. Steel structure bridges also form some concave areas where water may accumulate due to the complexity of various stiffening plates, such as the positions of stiffening ribs of the anchor lugs of the suspenders. The aforementioned concave areas where water may accumulate usually have a small area, but they dry slowly, are scattered in locations, and are difficult to drain using conventional drainage pipes.

[0004] In bridge design, the aforementioned concave areas where water may accumulate are difficult to completely avoid in the design of the main structure of the bridge, and are often exposed during the construction and operation stages. If not handled, they will have a negative impact on the aesthetics and durability of the bridge. Utility Model Content

[0014] Furthermore, a fixing structure is provided at the edge of the water guide cover plate, and the fixing structure can reliably fix the water guide cover plate on the bridge component body to prevent the water guide cover plate from loosening or falling off.

[0015] Furthermore, the specific form of the fixing structure is determined according to the material of the bridge component body and the water guide cover plate, and the fixing structure adopts one of welds, bolts, structural adhesive or other forms.
