Drainage pipe with anti-blocking function for roads and bridges

Abstract

The invention discloses a drainage pipe with an anti-blocking function for roads and bridges. The drainage pipe comprises a first pipeline, a second pipeline, a manhole cover, fixing blocks and teeth.The second pipeline is fixedly connected to the surface of the left side of the first pipeline, inner cavities are formed in the second pipeline and the first pipeline, a well lid is placed on the top surface of the first pipeline, a through hole is formed in the outer surface of the well lid, an escalator is fixedly arranged on the inner surface of the first pipeline, and a blocking plate is connected to the left side of the inner surface of the first pipeline. According to the drainage pipe with the anti-blocking function for roads and bridges, once blocking occurs, water slowly increases,a buoyancy block pulls a twist rod to ascend to extrude a convex block under the action of buoyancy so that the convex block drives a disc block to be engaged with a circular ring block through the teeth, the circular ring block is driven to rotate to pull a second filter plate through a connecting rod, the second filter plate and the third filter plate are rotated so as not to block the fixed block any more, and impurities fall off to prevent blockage.

Description

technical field [0001] The invention relates to the technical field related to roads and bridges, in particular to a drainage pipe for roads and bridges with an anti-clogging function. Background technique [0002] Roads and bridges are an indispensable part of people's lives. Roads provide people with improved transportation convenience and can reach a certain place more quickly, while bridges are a kind of traffic road that can span two regions, which is more convenient and improved. The transportation is convenient, and after the road and bridge are built, there needs to be a drainage pipe through which the accumulated water on the road and bridge can be drained, but the drainage pipe has some disadvantages: [0003] First, common drainage pipes can drain water, but they do not have the function of preventing clogging. Once clogged, the accumulated water will gradually increase and it will be more difficult to clean; [0004] Second, common drainage pipes cannot perform ...
