Description

Technical Field

[0001] The utility model relates to the technical field of bridge deck drainage, and more specifically to a side drainage structure of a concrete bridge. Background Art

[0002] As environmental and landscape requirements gradually increase, the traditional concrete bridge drainage has a tendency to change from direct discharge to centralized collection and discharge, such as across lakes or municipal concrete bridges. Drainage pipes usually use external PVC pipes, which have many structural connection points and poor landscape effects. They are prone to aging, damage, and water seepage at elbows and tees. Even the PVC pipe falls under the bridge as a whole, which greatly affects driving safety and causes adverse social impacts.

[0003] When the main bridge has wind nozzles on both sides of the main beam, in order to maintain the consistency of the overall landscape effect, the concrete approach bridge usually adopts a section consistent with the main bridge outline, and the concrete box beam wind nozzle adopts a solid block, which increases the deadweight of the structure. In addition, due to the inconsistency of the bridge deck drainage system, the drainage systems of the main and approach bridges are designed separately. The main bridge usually has a hidden drainage ditch in the wind nozzle structure, and the approach bridge part usually uses an external PVC pipe, which is inconsistent with the overall landscape. Therefore, it is urgent to improve the technology of the bridge deck drainage structure to improve this equipment.

[0004] Therefore, the utility model proposes a concrete bridge side drainage structure. Utility Model Content

[0005] 1. Technical issues to be solved

[0006] In view of the problems existing in the prior art, the purpose of the utility model is to provide a side drainage structure of a concrete bridge, which can reduce the deadweight of the structure by adopting a lighter steel structure wind nozzle consistent with the cross-section of the main bridge. A hidden drainage system is designed in the steel structure wind nozzle suspended on the side of the concrete beam, which has a good landscape effect and maintains the consistency of the drainage systems of the main and approach bridges. The top surface of the steel structure wind nozzle adopts a detachable transparent steel grille, which is convenient for maintenance personnel to directly carry out inspections and silt removal on the bridge deck without having to use a jacking vehicle for inspection and maintenance under the bridge. It also solves the problem that conventional PVC pipes are blocked and difficult to clear, and at the same time solves the problem that conventional concrete suspended steel structures use embedded parts for welding connections that cannot be replaced during operation, or the problem that flange connections cannot adjust the installation accuracy.
