Description

Technical Field

[0001] The utility model belongs to the technical field of bridge maintenance, and particularly relates to a large-span steel tube concrete main chord rainwater collector and drainer. Background Art

[0002] As an important part of modern transportation infrastructure, long-span bridges are widely used in key transportation nodes such as large highways, high-speed railways and cross-sea bridges. The notable feature of this type of bridge is its large span, which can withstand extremely high traffic loads and harsh natural environments.

[0003] On rainy days, especially during heavy rain or rainstorms, rainwater will flow down the main chord of the bridge quickly. Due to the high height of the long-span bridge, these water flows form a faster flow rate under the action of gravity, and carry a strong impact force. This strong scouring action poses a direct threat to the concrete arch seat at the bottom of the bridge. Under the long-term scouring of rainwater, the surface of the concrete arch seat will gradually be eroded, and cracks, peeling and other structural damage phenomena will occur, which will lead to the destruction of the structural integrity of the concrete arch seat, resulting in a decrease in its bearing capacity, and then affecting the safety and stability of the entire bridge.
