Description

Technical Field

[0001] The utility model relates to the technical field of road and bridge structures, in particular to an elevated road and bridge structure with a rapid drainage function. Background Art

[0002] Roads and bridges are generally composed of several major parts, including roadbeds, pavements, bridges, tunnel projects, and traffic engineering facilities. Many aspects must be considered during the construction of roads and bridges. Among them, the drainage system of roads and bridges is very critical in the entire road and bridge construction process. Since summer is a season with a relatively concentrated occurrence of extreme weather, a large amount of rainfall will bring great pressure to the drainage of roads and bridges. It is very easy for the road to be seriously flooded, resulting in vehicles being unable to pass. Therefore, it is very necessary to improve the drainage facilities of roads and bridges.

[0003] In existing road and bridge drainage facilities, the drainage outlets are mainly set on the road surface and covered and supported by mesh manhole covers. However, since the manhole covers are flush with the road surface, it is very easy for floating objects to completely block the drainage outlets, resulting in the inability to quickly drain rainwater, and then causing waterlogging that makes it impossible for vehicles to pass. Utility Model Content

[0004] Technical issues solved:

[0005] In view of the deficiencies of the prior art, the present invention provides an elevated road bridge structure with a rapid drainage function, thereby solving the technical problems mentioned in the background technology.

[0006] Technical solution:

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: it includes a base, an asphalt pavement, a boss and a drain outlet, a prefabricated baffle is provided at the drain outlet, one side of the prefabricated baffle is arc-shaped, and a protrusion is provided on the top to be clamped at the edge of the boss, and the arc-shaped surface of the prefabricated baffle is provided with a drainage hole.

[0008] Furthermore, a prefabricated steel cage is fixedly connected to the side of the prefabricated baffle arc surface facing the boss.

[0009] Furthermore, the drainage holes are arranged in multiple equal intervals.

[0010] Furthermore, the prefabricated steel cage is cross-arranged with a plurality of drainage holes.

[0011] Furthermore, the bottom of the arc-shaped surface of the prefabricated baffle is overlapped on the asphalt pavement.

[0012] Furthermore, the prefabricated baffle is a prefabricated concrete part.

[0013] Furthermore, the vertical side surface of the prefabricated steel cage contacts the vertical side surface of the boss.

[0014] Furthermore, the prefabricated steel cage may also be embedded in the side surface of the boss.

[0015] Furthermore, the prefabricated steel cage is located in a space enclosed by the prefabricated baffle and the boss.

[0016] Furthermore, the prefabricated steel cage covers the range of the drain outlet.

[0017] In one possible implementation

[0018] Beneficial effects:

[0019] In this solution, a prefabricated baffle is set at the drainage outlet, and one end of the prefabricated baffle is clamped on a boss higher than the road surface through a protrusion, and the other end of the prefabricated baffle is overlapped on the asphalt road surface. In this way, a height difference will be formed between the bottom and top of the prefabricated baffle, and at the same time, a height difference will be formed between the drainage holes set on the prefabricated baffle. In this way, it is difficult for floating objects to completely block the drainage holes, and rainwater can still be discharged through the drainage outlet.

[0020] In this solution, since one side of the prefabricated baffle is higher than the road surface, the floating objects will be as close to the edge of the road surface as possible and will be blocked by the prefabricated baffle, which makes it easier to clean up the floating objects.

[0021] In this solution, by setting up a prefabricated steel cage, on the one hand, it can effectively cooperate with the protrusions on the prefabricated baffle, thereby supporting the prefabricated baffle, which is beneficial to improving the stability of the installation of the prefabricated baffle. On the other hand, it can effectively cover the drain outlet, which can effectively prevent larger stones from falling into the drain outlet and causing blockage of the drain outlet.

[0022] Additional aspects and advantages of the present invention will be given in part in the following description and will become apparent from the following description or learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0034] Example 1:

[0035] Reference Figures 1 to 4 The embodiment of the present invention is an elevated road bridge structure with a rapid drainage function, which includes a base 1, an asphalt pavement 2, a boss and a drain outlet 3. The bosses are arranged on both sides of the base 1, and a prefabricated baffle 4 is provided at the drain outlet 3. One side of the prefabricated baffle 4 is arc-shaped, and a protrusion is provided on the top of the prefabricated baffle 4 to be clamped in a groove at the edge of the boss, and the bottom of the arc-shaped surface overlaps the asphalt pavement 2, so that the prefabricated baffle 4 is higher than the asphalt pavement 2. Since the prefabricated baffle 4 is set higher than the asphalt pavement 2, it is also possible to quickly clean up debris near the prefabricated baffle 4 by using equipment such as a rake, thereby accelerating the drainage speed of rainwater on the road bridge;

[0036] The arc-shaped surface is provided with multiple and equidistant drainage holes 6, which can effectively increase the drainage speed. In this way, when there is too much rain on the road bridge during heavy rain, due to the height difference of the drainage holes 6 provided on the arc-shaped surface, when floating obstacles float near the drainage holes 6, they will not be completely blocked, so that the drainage can still be guaranteed to be smooth.

[0037] A plurality of equally spaced drainage holes 6 are provided on the arc-shaped surface, which can effectively increase the drainage speed. The prefabricated steel cage 5 is fixed on the prefabricated baffle 4, and the prefabricated steel cage 5 is arranged crosswise with the plurality of drainage holes 6. The prefabricated steel cage 5 covers the range of the drainage outlet 3, which can effectively prevent larger stones from entering the drainage outlet 3, thereby effectively preventing water flow blockage in heavy rain weather.

[0038] The prefabricated baffle 4 is a prefabricated concrete part, which can reduce the difficulty of construction operation and have lower requirements on the construction environment. On the other hand, it can effectively improve construction efficiency and reduce construction costs.

[0039] The vertical side surfaces of the prefabricated steel cage 5 are in contact with the vertical side surfaces of the boss, which can effectively cooperate with the protrusions on the prefabricated baffle 4, further improving the stability of the installation of the prefabricated baffle 4. By providing the prefabricated steel cage 5, on the one hand, it can effectively cooperate with the protrusions on the prefabricated baffle 4, thereby supporting the prefabricated baffle 4, which is beneficial to improving the stability of the installation of the prefabricated baffle 4. On the other hand, it can effectively cover the drain outlet 3, which can effectively prevent larger stones from falling into the drain outlet 3, thereby causing the drain outlet 3 to be blocked.

[0040] When pedestrians step on or cars run over the prefabricated baffle 4, the prefabricated steel cage 5 can effectively support the prefabricated baffle 4 to prevent the prefabricated baffle 4 from breaking or being damaged;

[0041] The asphalt pavement 2 is laid on the base 1 and is located between the drainage outlets 3 on both sides. By setting the asphalt pavement 2 to be higher in the middle and lower on both sides, rainwater can be effectively prevented from gathering in the middle of the pavement to form water accumulation.

[0042] Example 2:

[0043] Reference Figures 5 to 7 This embodiment makes the following improvements based on the first embodiment:

[0044] By pre-embedding the prefabricated steel cage 5 on the vertical side of the boss and ensuring that the prefabricated steel cage 5 does not contact the prefabricated baffle 4, the prefabricated steel cage 5 can be effectively ensured to form a complete long strip shape, which can better cover the range of the drain outlet 3 and help reduce the possibility of larger stones falling into the drain outlet 3 and causing water blockage. When the prefabricated baffle 4 is removed, the prefabricated steel cage 5 can independently block the debris at the drain outlet 3, thereby increasing the water permeability of the drain outlet 3.

[0045] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
