Detailed Description

The technical solution of the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention, and all the directional indicators (such as upper, lower, left, right, front and back 8230; etc.) in the present invention are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the accompanying drawings), and if the specific posture is changed, the directional indicator is also changed accordingly.

As shown in fig. 1-3, the present embodiment provides a bridge drainage structure, including a bridge body 1, guardrails 2 are disposed on two sides of the bridge body 1, the bridge body 1 and the guardrails 2 are of an integral structure and are all prefabricated, a bridge deck of the bridge body 1 is inclined from the middle to two sides, and the inclination is 1.5-2%, a pavement structure 3 is laid on the top surface of the bridge body 1, and the inclination is identical to that of the bridge body 1, buffer slots 4 are formed on two side edges of the pavement structure 3, the side walls of the guardrails 2 and the top surface of the bridge body 1, during drainage and driving of vehicles on a road surface, the buffer slots 4 can precipitate dust and small particle impurities, so as to achieve precipitation and filtration of fine impurities, drainage slots 5 are disposed along the length direction in the guardrail 2, the drainage slots 5 are inclined, drainage can be performed rapidly, rain grates 6 are installed on the side walls of the guardrails 2, large particle impurities are filtered through the rain grates 6, and accumulated water flows along the top surface of the bridge deck structure 3 during drainage.
