Description

Technical Field

[0001] The utility model relates to the technical field of bridge deck drainage, in particular to a highway bridge deck drainage structure. Background Art

[0002] Bridge drainage facilities are ancillary projects of the entire road and bridge project. If the bridge cannot drain water in time, the safety and comfort of driving on the bridge deck will not meet the requirements, and in severe cases it will cause damage to the bridge.

[0003] In order to improve the drainage effect of highway bridges, the prior art has made many improvements to the drainage structure of highway bridge decks, such as the patent with the publication number CN214831893U, which discloses a semi-implicit vertical drainage structure of a highway bridge deck, including an open drainage ditch, a longitudinal drainage pipe, a vertical drainage pipe and a longitudinal drainage ditch; the open drainage ditch is arranged between the guardrail and the bridge deck, the longitudinal drainage pipe is buried at the bottom of the guardrail, the open drainage ditch is connected to a plurality of longitudinal drainage pipes, the outlet of the longitudinal drainage pipe is connected to the inlet of the vertical drainage pipe, the outlet of the vertical drainage pipe is connected to the inlet of the diversion pipe, the outlet of the diversion pipe is connected to the inlet of the vertical drainage pipe, the vertical drainage pipe is fixed on the outside of the bridge pier, and a longitudinal drainage ditch is arranged under the vertical drainage pipe. The open ditch drainage is combined with the longitudinal drainage pipe buried at the bottom of the guardrail, which has a strong drainage capacity, can concentrate precipitation to the reserved drainage ditch, and is more friendly to the ecological environment.

[0004] The above patent has obvious beneficial effects, but still has the following shortcomings in actual operation:

[0005] In the above-mentioned comparative documents, an open drainage ditch is set up, and rainwater flows into the longitudinal drainage pipe through the open drainage ditch and is discharged through the vertical drainage pipe. However, in reality, there will be a large amount of impurities on the highway bridge deck, and because the grilles in the prior art can only block larger impurities, smaller impurities will enter the longitudinal drainage pipe through the open drainage ditch. If things go on like this for a long time, the longitudinal drainage pipe will be blocked, and then the drainage of the highway bridge deck will be untimely. Therefore, there is an urgent need in this field to improve the drainage structure of the highway bridge deck, so as to solve the defects of the prior art. Utility Model Content
