Description

Technical Field

[0001] The utility model belongs to the technical field of drainage structures, in particular to a drainage structure for a connection section between a bridge culvert and a roadbed. Background Art

[0002] In cities with heavy rainfall, water is easily accumulated at the junction of bridges and culverts and roadbeds. If there is a problem with drainage at the junction of bridges and culverts, rainwater or accumulated water will seep into the interior of the roadbed through cracks in the bridgehead or the road surface near the bridgehead. If the accumulated water cannot be drained for a long time, it will easily shorten the life of the roadbed as a whole and cause deformation. Therefore, a drainage structure is needed for the junction of bridges and culverts and roadbeds.

[0003] The drainage structure at the junction of the bridge culvert and the roadbed mainly includes drainage ditches, drainage mechanisms, and mixing blades. When the bridge culvert is blocked, the motor is started to drive the mixing blades to crush the blocked silt, and then the silt and rainwater are discharged through the drainage ditch through the drainage mechanism.

[0004] In the existing drainage structure of the connection section between the bridge culvert and the roadbed, the blockage of the bridge culvert is usually caused by the accumulation of various impurities due to rainwater erosion. The existing device is inconvenient to clean it, and the drainage efficiency of the existing device is not high. Therefore, to address the above problems, a drainage structure of the connection section between the bridge culvert and the roadbed is proposed. Utility Model Content
