Description

Technical Field

[0002] China has a vast territory and complex terrain. Highway transportation and bridge construction play an important role in connecting various regions. However, during rainy days, the accumulated water on the bridge or highway surface can easily cause the car tires to skid, thereby leading to out-of-control driving and traffic accidents. In addition, the accumulated water on the road surface will also cause traffic jams and damage to the highway bridge structure, shortening its service life. Therefore, drainage facilities are generally installed on the road surface to quickly drain the accumulated water and ensure driving safety.

[0003] The existing drainage systems are usually designed with inclined road surfaces and drainage holes are provided on both sides. A grid plate is installed at the top of the drainage hole to block large garbage and sundries, and the water flow is guided to the drainage system under the bridge through a channel connected to the pipeline below. However, during long-term use, the drainage system also faces challenges. Garbage, gravel, small stones and dust particles will accumulate on the road surface. During rainy days, these sundries will mix with rainwater to form sludge, and some small garbage, small stones and sludge will pass through the grid plate and enter the drainage hole and pipeline. After a long time of accumulation, these sundries are likely to block the pipeline. Especially in light rain weather, the water flow is slow and the sludge is more likely to precipitate, exacerbating the blockage problem. Summary of the Utility Model

[0004] The embodiments of this application provide a drainage facility for preventing blockage of highway bridge decks, which solves the blockage problem in the use process of the existing drainage system.

[0005] An embodiment of the present application provides an anti-blocking highway bridge deck drainage facility, including: a plurality of drainage holes, which are all vertically arranged on both sides of the road surface and are spaced along the length direction of the road surface; a plurality of grid plates, which are respectively arranged on the tops of the corresponding drainage holes and are configured to filter debris; a plurality of sedimentation tanks, which are respectively arranged at the bottoms of the corresponding drainage holes; a plurality of first filter meshes, which are respectively horizontally arranged between each drainage hole and the sedimentation tank; a plurality of overflow pipes, one end of which is communicated with the side wall of the corresponding drainage hole, and the other end of which is communicated with the top of the corresponding sedimentation tank, and the end of the overflow pipe facing the drainage hole is located above the first filter mesh; a plurality of second filter meshes, which are respectively arranged at the ends of the corresponding overflow pipes facing the drainage holes; and a plurality of drain pipes, which are respectively arranged at the tops of the corresponding sedimentation tanks, and the end away from the sedimentation tank is communicated with a drainage system, and the drainage system is configured to extract the sewage in the drain pipes; wherein, the height of the side of the overflow pipe facing the drainage hole is higher than the height of the side facing the sedimentation tank; the aperture of the grid plate is larger than the apertures of the first filter mesh and the second filter mesh.

[0006] In a possible implementation manner, the anti-blocking highway bridge deck drainage facility further includes a plurality of channels; both ends of the plurality of channels are communicated with the bottom of the corresponding drainage hole and the top of the sedimentation tank; the plurality of first filter meshes are respectively horizontally arranged in the corresponding channels; one end of the plurality of overflow pipes is communicated with the side wall of the corresponding channel; the diameter of the drainage hole is smaller than the diameter of the channel.

[0007] In a possible implementation manner, the anti-blocking highway bridge deck drainage facility further includes a plurality of first connecting pipes; the plurality of first connecting pipes are respectively vertically arranged at the tops of the corresponding sedimentation tanks, and the end away from the sedimentation tank is communicated with the side of the overflow pipe away from the drainage hole.

[0008] In a possible implementation manner, the anti-blocking highway bridge deck drainage facility further includes a plurality of second connecting pipes; the plurality of second connecting pipes are respectively vertically arranged at the tops of the corresponding sedimentation tanks, and the end away from the sedimentation tank is communicated with the end of the drain pipe away from the drainage system.

[0012] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects:

[0013] The embodiments of the present application provide an anti-blocking highway bridge deck drainage facility. When there is water accumulation on the road surface, the sewage first flows into the sedimentation tank below through the drain hole for sedimentation. During this process, the grid plate effectively blocks larger sundries in the sewage, and the first filter mesh further intercepts smaller sundries, thereby preventing impurities from directly entering the drainage system. If there is a large amount of rain or the first filter mesh is blocked by sundries and affects the flow rate, once the sewage level exceeds the second filter mesh, it will quickly flow into the sedimentation tank through the overflow pipe to ensure unobstructed sewage flow. After the suspended matter in the sedimentation tank is sedimented, the clean water body is then discharged through the drain pipe, significantly reducing the impurity content in the sewage and effectively reducing the risk of blocking the drainage pipe.

[0014] The combined use of the grid plate, the first filter mesh, and the second filter mesh constructs an efficient multi-level filtration system. First, the grid plate filters large sundries; then, the first filter mesh refines the filtration to reduce the impurities entering the sedimentation tank; finally, the second filter mesh intercepts small sundries again at the overflow pipe orifice to ensure that the water body entering the sedimentation tank is relatively clean. The sedimentation tank not only further purifies the water quality but also intercepts most of the solid impurities through the sedimentation effect, reducing the pollution to the downstream drainage system.

[0015] In addition, the design of the overflow pipe can not only divert the sewage when necessary to reduce the burden on the first filter mesh but also ensure that the water flow can smoothly flow towards the sedimentation tank under the action of pressure through its height difference.

[0016] In summary, the anti-blocking highway bridge deck drainage facility provided in the embodiments of the present application shows significant advantages and positive effects in improving drainage efficiency, preventing blockage, protecting the bridge deck and the environment, etc. Description of the Drawings

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific situations.

[0023] The embodiments of the present application provide an anti-blocking highway bridge deck drainage facility, as Figures 1 to 2 shown. The anti-blocking highway bridge deck drainage facility includes a plurality of drainage holes 1, a plurality of grid plates 2, a plurality of sedimentation tanks 3, a plurality of first filter screens 4, a plurality of overflow pipes 5, a plurality of second filter screens 6, and a plurality of drain pipes 7.

[0024] A plurality of drain holes 1 are vertically arranged on both sides of the road surface and are spaced along the length direction of the road surface. A plurality of grid plates 2 are respectively arranged on the tops of the corresponding drain holes 1 and are configured to filter debris. A plurality of sedimentation tanks 3 are respectively arranged at the bottoms of the corresponding drain holes 1. A plurality of first filter meshes 4 are horizontally arranged between each drain hole 1 and the sedimentation tank 3. One ends of a plurality of overflow pipes 5 are communicated with the side walls of the corresponding drain holes 1, and the other ends thereof are communicated with the tops of the corresponding sedimentation tanks 3. The ends of the overflow pipes 5 facing the drain holes 1 are located above the first filter meshes 4. A plurality of second filter meshes 6 are respectively arranged at the ends of the corresponding overflow pipes 5 facing the drain holes 1. And a plurality of drain pipes 7 are respectively arranged at the tops of the corresponding sedimentation tanks 3, and the ends thereof far away from the sedimentation tanks 3 are communicated with a drainage system, and the drainage system is configured to extract the sewage in the drain pipes 7. The drainage system described in the embodiments of the present application is the drainage system on the ground under an existing bridge. When it is detected that the sewage in the sedimentation tank 3 reaches a certain amount, the drainage system extracts the sewage in the sedimentation tank 3 through the drain pipe 7.

[0025] Among them, the overflow pipe 5 is designed such that the side facing the drain hole 1 is higher than the side facing the sedimentation tank 3, forming an inclined structure. This design facilitates the smooth flow of sewage in the overflow pipe 5, effectively reduces the residence time of sewage in the pipe, and further reduces the accumulation of sewage sediments in the overflow pipe 5, reducing the risk of blockage. The aperture of the grid plate 2 is larger than the apertures of the first filter mesh 4 and the second filter mesh 6.

[0026] Specifically, the grid plate 2 of the present application adopts a grid-like design with relatively large gaps, which can effectively block larger garbage and prevent them from entering the drainage system. The sedimentation tank 3 is used for sedimentation treatment of the water flow flowing in from the drain hole 1 to remove suspended matters and some impurities therein. A first filter mesh 4 for secondary filtration is specially arranged between the drain hole 1 and the sedimentation tank 3. The aperture of this mesh is smaller than that of the grid plate 2, and it can further block small garbage such as small wooden sticks and relatively large stones, ensuring that the water body entering the sedimentation tank 3 is relatively clean. Such a design combination not only improves the overall filtration efficiency of the drainage facilities but also effectively reduces the blockage risk of the subsequent drain pipe 7, which is of great significance for protecting the bridge deck of the highway bridge, improving driving safety, and maintaining environmental cleanliness.

[0027] It should be noted that when there is water accumulation on the road surface, the sewage first flows into the sedimentation tank 3 below through the drainage holes 1 for sedimentation. During this process, the grid plate 2 effectively blocks the larger debris in the sewage, while the first filter screen 4 further intercepts the smaller debris, thus preventing impurities from directly entering the drainage system. If there is a large amount of rainwater or the first filter screen 4 is blocked by debris, affecting the flow rate, once the water level of the sewage exceeds the second filter screen 6, it will quickly flow into the sedimentation tank 3 through the overflow pipe 5 to ensure unobstructed sewage flow. After the suspended matter in the sedimentation tank 3 is precipitated, the clean water body is then discharged through the drain pipe 7, significantly reducing the impurity content in the sewage and effectively reducing the risk of blockage of the drain pipe 7.

[0028] The combined use of the grid plate 2, the first filter screen 4 and the second filter screen 6 constructs an efficient multi-level filtration system. First, the grid plate 2 filters large debris; then, the first filter screen 4 refines the filtration to reduce the impurities entering the sedimentation tank 3; finally, the second filter screen 6 intercepts fine debris again at the mouth of the overflow pipe 5 to ensure that the water body entering the sedimentation tank 3 is relatively clean. The sedimentation tank 3 not only further purifies the water quality, but also intercepts most of the solid impurities through sedimentation, reducing the pollution of the downstream drainage system.

[0029] In addition, the design of the overflow pipe 5 can not only divert sewage when necessary, reducing the burden on the first filter screen 4, but also ensures that the water flow can smoothly flow towards the sedimentation tank 3 under the action of pressure through its height difference.

[0030] In summary, the anti-blocking highway bridge deck drainage facility provided by the embodiment of the present application shows significant advantages and positive effects in terms of improving drainage efficiency, preventing blockage, protecting the bridge deck and the environment.

[0031] In the embodiment of the present application, the anti-blocking highway bridge deck drainage facility further includes a plurality of channels 8. Both ends of the plurality of channels 8 are communicated with the bottom of the corresponding drainage holes 1 and the top of the sedimentation tank 3. A plurality of first filter screens 4 are respectively horizontally arranged in the corresponding channels 8. One end of each of the plurality of overflow pipes 5 is communicated with the side wall of the corresponding channel 8. The diameter of the drainage hole 1 is smaller than the diameter of the channel 8.

[0032] It should be noted that the diameter of the drainage hole 1 is smaller than the diameter of the channel 8. This design enables the channel 8 to accommodate more sewage, thus maintaining efficient drainage capacity even when there is heavy rain. At the same time, installing the first filter screen 4 in the channel 8 can reduce the obstruction of the first filter screen 4 to the sewage flow rate because the sewage has a larger flow space in the channel 8. In addition, due to the larger diameter of the channel 8, the installation area of the first filter screen 4 is also correspondingly increased, which further reduces the risk of the filter screen being blocked and ensures the long-term stable operation of the drainage system.

[0033] In the embodiment of the present application, the anti-blocking highway bridge deck drainage facility further includes a plurality of first connecting pipes 9. The plurality of first connecting pipes 9 are respectively vertically arranged on the top of the corresponding sedimentation tank 3, and one end thereof far from the sedimentation tank 3 communicates with one side of the overflow pipe 5 far from the drainage hole 1.

[0034] Specifically, the overflow pipe 5 is a straight pipe, which is convenient for installing the overflow pipe 5.

[0035] In the embodiment of the present application, the anti-blocking highway bridge deck drainage facility further includes a plurality of second connecting pipes 10. The plurality of second connecting pipes 10 are respectively vertically arranged on the top of the corresponding sedimentation tank 3, and one end thereof far from the sedimentation tank 3 communicates with one end of the drain pipe 7 far from the drainage system.

[0036] It should be noted that after the sewage enters the sedimentation tank 3, it will be subjected to sedimentation treatment for a period of time. In this way, in the case of less rain and slower water flow velocity, the sewage can have more sufficient time for sedimentation, thereby improving the sedimentation effect and better purifying the sewage. Subsequently, the sewage after sedimentation treatment flows into the drain pipe 7 through the second connecting pipe 10 to continue the subsequent drainage process. Such a design helps to ensure that the discharged water quality meets the standards and reduces environmental pollution.

[0037] In the embodiment of the present application, the second connecting pipe 10 and the first connecting pipe 9 are respectively located on both sides of the corresponding drainage hole 1.

[0038] It should be noted that the second connecting pipe 10 and the first connecting pipe 9 are respectively located on both sides of the drainage hole 1, forming two independent drainage paths.

[0039] In the embodiment of the present application, the height of one side of the drain pipe 7 facing the second connecting pipe 10 is higher than the height of the side facing the drainage system.

[0040] It should be noted that the drain pipe 7 is designed such that the height of the side facing the second connecting pipe 10 is higher than the side facing the drainage system. Such a design can promote the rapid flow of sewage in the drain pipe 7, thereby effectively reducing the residence and sedimentation time of debris in the sewage in the pipe, and further ensuring the unobstructed drainage system.

[0041] In the embodiment of the present application, a plurality of second filter meshes 6 are respectively vertically arranged at one end of the corresponding overflow pipe 5 facing the drainage hole 1.

[0042] Specifically, the second filter mesh 6 is flush with the inner side wall of the channel 8, so that the second filter mesh 6 blocks the debris in the sewage in the channel 8 to prevent the debris in the sewage from entering the overflow pipe 5. Moreover, the second filter mesh 6 is vertically arranged and is not easily blocked, further improving the overall performance of the drainage facility.

[0043] The various embodiments in this specification are described in a progressive manner. For the same or similar parts among the various embodiments, reference can be made to each other. Each embodiment focuses on the differences from other embodiments.

[0044] The above embodiments are only used to illustrate the technical solutions of the present application, rather than limiting the present application; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the present application.
