Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of highway bridges, in particular to a device for preventing water discharge pipes from blocking highway bridges. Background Art
[0002] At present, drainage facilities are an important part in the operation of bridges. Common drainage facilities are mostly open bridge deck drainage holes directly connected to drainage pipes. Although they can meet normal drainage functions, drainage facilities are easily blocked by debris and silt during use, resulting in drainage difficulties. As a result, a large amount of rainwater will gather on the bridge deck when it rains. On the one hand, the accumulated rainwater will reduce the anti-skid performance of the bridge deck, easily cause traffic accidents, and affect normal driving safety. On the other hand, it will also corrode the bridge structure, which has an adverse effect on the service life of the bridge. In addition, the setting of the drainage holes makes it more difficult to clean up the debris, increasing the workload of maintenance personnel.
[0003] In summary, the current highway bridge drainage facilities lack anti-blocking devices. Summary of the invention

The device is symmetrically arranged as a whole, including a drainage pipe 1 and a top cover plate 3, wherein the top cover plate 3 is arranged at the upper end of the drainage pipe 1; it also includes a drainage pipe 2, a solid filter screen 8, a water collection device 10 and a sludge collection device 4.
[0033] Among them, the drain pipe 2 is arranged inside the drainage pipe 1 and is fixed to the lower end of the top cover plate 3 by threads. A plurality of small holes are provided on the lower part of the pipe wall of the drain pipe 2, which are used to allow the rainwater collected in the drain pipe 2 to be discharged into the drainage pipe 1 through the small holes on the inner wall to complete the drainage work.
[0034] A first baffle 7 is fixed on the inner wall of the drain pipe 2 at its opening, and is used to fix a solid filter screen 8 .
[0035] The solid filter screen 8 is placed on the first baffle plate 7, so that the staff can remove it in time for cleaning later. The upper end surface of the solid filter screen 8 is close to the lower end surface of the top cover plate 3. A number of small holes are provided on the bottom and side walls of the solid filter screen 8 for preliminary filtering of larger solid debris.
[0036] A second baffle 9 is fixed on the inner wall of the upper middle portion of the drain pipe 2 for fixing the water collecting device 10 .
[0037] The water collecting device 10 is placed on the second baffle 9, so that the staff can take it down in time for cleaning later, and is located below the solid filter screen 8. The water collecting device 10 is in the shape of a flat funnel, and is provided with a plurality of small holes on its bottom and side walls. The water collecting device 10 collects a large amount of silt directly through the silt collecting port of the silt collecting device 4 into the silt collecting device 4 for storage, and rainwater and a small amount of silt flow into the drain pipe 2 through the small holes on the bottom and side walls of the water collecting device 10.
[0038] The first baffle 7 and the second baffle 9 are both in annular shape.
[0039] Furthermore, a drain pipe bottom plate 5 is provided at the lower end of the drain pipe 2. The drain pipe bottom plate 5 is a cylinder with a hollowed-out middle portion, and the hollowed-out middle portion is a sludge collection opening.
[0040] An oblique flow plate 6 is provided at the upper end of the drain pipe bottom plate 5, and the oblique flow plate 6 is fixed on the inner wall of the drain pipe 2. The diameter of the hollowed-out middle part of the oblique flow plate 6 is consistent with the diameter of the hollowed-out middle part of the drain pipe bottom plate 5. The vertical section of the oblique flow plate 6 is slope-shaped, and the bottom edge of the slope is aligned with the inner edge of the drain pipe bottom plate 5, so as to allow the sludge to further settle into the sludge collection device 4.
[0041] The sludge collecting device 4 is a cylinder with an opening at the top and a hollow interior. The upper end of the sludge collecting device 4 is fixedly connected to the lower end surface of the drain pipe bottom plate 5 by threads for storing sludge.
[0042] The working principle of this embodiment is:
[0043] When it rains, debris and silt in the runoff from the bridge deck flow into the drain pipe 2 through the water inlet on the top cover plate 3. The solid filter screen 8 installed at the mouth of the drain pipe 2 first collects solid debris with larger volume and performs preliminary filtration. The rainwater and silt after preliminary filtration flow into the water collection device 10 below the solid filter screen 8. The water collection device 10 collects a large amount of silt directly into the silt collection device 4 through the silt collection port of the silt collection device 4 for storage. The rainwater and a small amount of silt flow into the drain pipe 2 through the small holes on the bottom and side walls of the water collection device 10. The slope of the inclined flow plate 6 allows the silt to further settle in the silt collection device 4. The rainwater collected in the drain pipe 2 is discharged into the drainage pipe 1 through the small holes on the inner wall of the drain pipe 2, and the drainage work is completed.
[0044] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention.
