Device for removing, draining and aerating water at water outlet of municipal bridge

Abstract

A device for removing, draining and aerating water at water outlet of municipal bridges comprises: an outer sleeve connector; a working cavity is formed in the outer sleeve connector and penetrates through the outer sleeve connector, one end of an opening of the outer sleeve connector is large, the other end of the outer sleeve connector is small, a rain grate is embedded in the large opening end of the outer sleeve connector, and the other end of the outer sleeve connector is in a mesh shape. According to the structure, water accumulation after water seepage in the working cavity is avoided; a rectifying and filtering mechanism is arranged in the working cavity and drives the rotational flow rainwater to rotate reversely, so that the rotational flow rainwater is changed into direct flow to remove entrained air in the rainwater; a silt removing mechanism is arranged on the side, away from the rain grate, in the working cavity. Besides, sediment removal mechanism can automatically clean filtered sediment, and swirling rainwater can be rotated in the opposite direction through the rectification hopper by means of the weight of the rainwater, so that air entrainment in the swirling rainwater is eliminated and the rainwater can reach a full retention state when flowing into the water drainage pipe; therefore, the siphon effect is generated, and bridge floor water drainage is more efficient.

Description

technical field [0001] The invention belongs to the field of bridge drainage, in particular to a device for removing drainage and aeration at municipal bridge drainage outlets. Background technique [0002] With the increase of the frequency of rainstorms, the bridge deck drainage problem of urban viaducts has been highly concerned by people. The drainage outlets of traditional urban viaduct bridge decks will be aerated due to rainwater swirling and sediment deposition in drainage pipes. The drainage of the pipeline is reduced, resulting in water accumulation on the bridge, and the aeration generated by the rainwater swirl will reduce the volume of rainwater in a certain volume, thereby reducing the drainage; and the sediment of the existing drainage pipeline will adhere to the pipe wall when the drainage is small On the surface, it is difficult to clean, and the deposition of sediment will reduce the inner diameter of the drainage pipe, resulting in a reduction in drainage....
