Description

Technical Field

[0001] The utility model relates to the technical field of urban drainage, in particular to an urban underpass road drainage system. Background Art

[0002] Urban underpass refers to a road built under a road. Compared with conventional road drainage facilities, the drainage of urban underpass has the following characteristics:

[0003] 1. The terrain of the city's underpass is low, precipitation is easy to accumulate, and drainage is difficult;

[0004] 2. Once the drainage system of the city's underpass fails, the water will flow downward, causing water accumulation on the lower road surface, hindering the normal traffic of vehicles and pedestrians.

[0005] Therefore, the anti-blocking function of the urban underpass drainage system is very important. Once the urban underpass drainage system is blocked, the urban underpass will not be able to be used normally. In order to improve the anti-blocking function of the urban underpass drainage system, a new type of urban underpass drainage system is proposed. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a city underpass drainage system, which is used to improve the anti-blocking function of the city underpass drainage system.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0008] A city underpass road drainage system comprises a water reservoir pre-buried underground, a mounting frame horizontally arranged on the ground, and a drainage pipe arranged between the water reservoir and the mounting frame, wherein a grille plate is installed in the mounting frame, a debris discharge groove is arranged on the side wall of the drainage pipe, a small debris baffle is obliquely arranged in the drainage pipe, and the lower end of the small debris baffle corresponds to the position of the debris discharge groove, a support plate fixedly installed in the drainage pipe is arranged below the small debris baffle, a guide plate located above the small debris baffle is obliquely arranged on the side of the inner wall of the drainage pipe close to the debris discharge groove, a debris pool is arranged on the side of the drainage pipe away from the road surface, and a cover plate is arranged on the debris pool.

[0009] Preferably, the height of the corresponding position of the mesh holes on the grid plate is lower than the height of the corresponding position of the top edge of the grid plate.

[0010] Preferably, the height of a corresponding position of the bottom end of the lower surface of the small debris baffle is lower than the height of a corresponding position of the bottom of the inner wall of the debris discharge groove.

[0011] Preferably, the size of the mesh holes on the grille plate is larger than the size of the mesh holes on the small debris baffle.

[0012] Preferably, the inclination angle of the guide plate is lower than the inclination angle of the small debris baffle.

[0013] Preferably, the minimum distance between the guide plate and the small debris baffle is not less than 5CM.

[0014] Preferably, the drain pipe is a round pipe or a square pipe, and the diameter or side length of the drain pipe is not less than 50CM.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] The utility model guides the flow of water by arranging a small debris baffle and a guide plate in the drain pipe. Leaves and small garbage entering the drain pipe are retained on the small debris baffle, and the water flows out through the drain pipe. The worker opens the cover plate, pulls out the small debris baffle, and cleans the garbage on the small debris baffle to prevent the debris from clogging the grille plate and the small debris baffle. At the same time, the grille plate and the small debris baffle bear the debris in a graded manner, which can also prevent the grille plate and the small debris baffle from being blocked, thereby improving the anti-blocking function of the urban underpass drainage system.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-4As shown, the utility model provides a technical solution: an urban underpass road drainage system, comprising a water reservoir 1 pre-buried underground, a mounting frame 2 horizontally arranged on the ground, and a drainage pipe 3 arranged between the water reservoir 1 and the mounting frame 2;

[0024] The drain pipe 3 is a round pipe or a square pipe, and the diameter or side length of the drain pipe 3 is not less than 50CM, which can be selected according to the needs and installation environment;

[0025] A grid plate 4 is installed in the mounting frame 2. The height of the corresponding position of the mesh hole of the grid plate 4 is lower than the height of the corresponding position of the top edge of the grid plate 4. The grid plate 4 has the function of guiding the water flow. The size of the mesh hole of the grid plate 4 is larger than the size of the mesh hole of the small debris baffle 5, and the flowing water is filtered in stages.

[0026] A debris discharge groove 301 is arranged on the side wall of the drain pipe 3, and a small debris baffle 5 is arranged obliquely in the drain pipe 3, and the lower end of the small debris baffle 5 corresponds to the position of the debris discharge groove 301, and the height of the corresponding position of the bottom end of the lower surface of the small debris baffle 5 is lower than the height of the corresponding position of the bottom of the inner wall of the debris discharge groove 301, ensuring that the small debris baffle 5 will not slide out of the debris discharge groove 301 when placed on the support plate 6;

[0027] A support plate 6 fixedly installed in the drain pipe 3 is arranged below the small debris baffle 5, and a guide plate 7 located above the small debris baffle 5 is arranged obliquely on the inner wall of the drain pipe 3 close to the debris discharge groove 301. The guide plate 7 guides the water flow and gives the water flow a sufficient flow distance. The water flows into the drain pipe 3, while the debris remains on the small debris baffle 5. A debris pool 8 is arranged on the side of the drain pipe 3 away from the road surface, and a cover plate 801 is arranged on the debris pool 8.

[0028] The inclination angle of the guide plate 7 is lower than that of the small debris baffle 5. The guide plate 7 guides and buffers the flowing water to reduce the flow velocity. The minimum distance between the guide plate 7 and the small debris baffle 5 is not less than 5CM to prevent the debris on the guide plate 7 from falling onto the small debris baffle 5.

[0029] Working principle:

[0030] Under the guidance of the pavement design, the water flow on the city underpass reaches the position of the grating plate 4 and flows downward through the grating plate 4. The grating plate 4 blocks larger branches and debris in the water flow. The water flow filtered by the grating plate 4 flows downward in the drain pipe 3. The water flow falling on the guide plate 7 is guided and buffered by the guide plate 7 and falls on the small debris baffle 5. The debris falling on the small debris baffle 5 moves downward along the slope of the small debris baffle 5. The small debris baffle 5 is pulled out through the worker cover 801 to clean the debris on the small debris baffle 5.

[0031] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.
