Furthermore, a plurality of sedimentation tanks are arranged on two sides of the highway section.

Further, the sedimentation tank is located below the highway section.

Further, the sedimentation tanks are uniformly spaced along one side of the highway section.

Further, a booster pump and a first switch valve are installed between the collecting pipeline and the sedimentation tank.

Further, a second switch valve is arranged between the sedimentation tank and the water drainage pipe.

Further, the drain pipes are all connected to a drain main pipe.

Furthermore, a filter screen is arranged in the drain pipe.

Compared with the prior art, the beneficial effects of the utility model are that: the sewage and the accumulated water on the surface of the highway section are introduced into the sedimentation tank through the collecting pipeline for filtration, oil separation, poison storage and sedimentation treatment, and the treated water is introduced into the greening watering system nearby, so that the sewage on two sides of the highway section is purified, the sewage is effectively recycled, the resources are saved, and the sedimentation tank is arranged at intervals to improve the sewage treatment efficiency.
