However, with the above technical scheme, when the rainfall is heavy, there will be water accumulation on the elevated bridge deck generally, which is mostly caused by the lack of drainage floor drain pipes and untimely drainage. In addition, there are no emergency backup drainage floor drain pipes, and the drainage speed is slow, causing water accumulation, which will then seep into the bridge and damage the durability of the bridge. In addition, the water on the bridge surface is slippery and traffic accidents are very likely to occur.

[0005] Therefore, those skilled in the art provide a drainage device for municipal roads and bridges to solve the problems raised in the above background technology. Utility Model Content

[0006] The purpose of the utility model is to provide a drainage device for municipal roads and bridges to solve the problems raised in the above-mentioned background technology.

DETAILED DESCRIPTION

[0025] See also Figure 1-4 A drainage device for a municipal road bridge includes a bridge deck 1, a bridge pier 2 and a bridge guardrail 3. The bridge deck 1 is located above the bridge pier 2. The upper surface of the bridge pier 2 is fixedly connected with a support seat 11. The upper surface of the support seat 11 is fixedly connected to the bottom surface of the bridge deck 1. By providing the support seat 11, the vibration of the bridge deck 1 is effectively alleviated, the stability of the bridge deck 1 is ensured, and the drainage mechanism 4 is also protected.

[0026] The right side of the bridge deck 1 is fixedly connected to the left side of the bridge guardrail 3. A drainage mechanism 4 is arranged below the bridge deck 1. The drainage mechanism 4 includes a thick water pipe 401. Two vertical pipe racks 7 are fixedly connected to the outer surface of the thick water pipe 401. The left side of each vertical pipe rack 7 is fixedly connected to the right side of the pier 2. By providing the vertical pipe rack 7, the thick water pipe 401 is effectively fixed to the pier 2, thereby increasing the stability of the thick water pipe 401.

[0027] The top end of the thick water pipe 401 passes through the bridge deck 1 and is fixedly connected to a funnel pipe 402. The funnel pipe 402 is located inside the bridge deck 1. The inner wall of the funnel pipe 402 is clamped with a funnel basket 403. The outer surface of the thick water pipe 401 is fixedly connected to a hanging thick pipe rack 8. The top end of the hanging thick pipe rack 8 is fixedly connected to the bottom surface of the bridge deck 1. By providing the hanging thick pipe rack 8, the thick water pipe 401 is effectively fixed to the bottom surface of the bridge deck 1, so that the hanging thick water pipe 401 has a stable effect.

[0028] The inner wall of the funnel basket 403 is rotatably connected with a handle 404, the inner wall of the funnel tube 402 is clamped with a floor drain cover 405, and the floor drain cover 405 is located above the funnel basket 403. The outer surface of the thick water pipe 401 is fixedly connected to two thin water pipes 406, and the outer surface of each thin water pipe 406 is fixedly connected to a hanging thin pipe rack 9, and the top of each hanging thin pipe rack 9 is fixedly connected to the bottom surface of the bridge deck 1. By providing the hanging thin pipe rack 9, the two thin water pipes 406 are effectively fixed to the bottom surface of the bridge deck 1, so that the hanging thin water pipes 406 have a stable effect.

[0029] The top end of each thin water pipe 406 passes through the bridge deck 1 and is fixedly connected to a floor drain 407. The bottom end of the thick water pipe 401 is fixedly connected to a buffer pipe 408. The bottom end of the buffer pipe 408 is fixedly connected to a curved pipe 5. A reinforcing ring 6 is sleeved on the outer surface of the curved pipe 5. By providing the curved pipe 5 and the reinforcing ring 6, the curved pipe 5 can deflect rainwater and flow out relatively smoothly to protect the foundation part around the bridge pier 2. The reinforcing ring 6 is used to reinforce the curved pipe 5 to increase the service life of the curved pipe 5.

[0030] The inner wall of the buffer tube 408 is fixedly connected to a fixed shaft 409, the outer surface of the fixed shaft 409 is rotatably connected to a fan blade 410, the inner wall of the bridge deck 1 is fixedly connected to a ground trough 411, the inner wall of the bridge guardrail 3 is fixedly connected to a vertical groove 412, and the outer surface of each thin water pipe 406 is fixedly connected to a cross pipe rack 10, and the left side of each cross pipe rack 10 is fixedly connected to the right side of the pier 2. By providing two cross pipe racks 10, the two thin water pipes 406 can be effectively fixed on the pier 2, thereby increasing the stability of the thin water pipes 406.

[0031] The working principle of the utility model is as follows: when in use, if the rainfall is small at this time, the rainwater will flow to the ground trough 411 along the slope of the bridge deck 1, and then enter the interior of the funnel pipe 402 through the floor drain cover 405. At this time, the rainwater falls into the funnel basket 403 through the floor drain cover 405. If there is some garbage accompanying the rainwater, it will be blocked by the ground trough 411 for the first time, and then screened again by the funnel basket 403. Most of the garbage will be isolated and blocked, and the garbage entering the interior of the rough water pipe 401 is small and not enough to block the pipe.

[0032] If the amount of rain is heavy and there is obvious water accumulation on the bridge deck 1, when the water overflows the ground trough 411, the funnel pipe 402 alone cannot drain the rainwater in time, and the rainwater will enter the interior of the bridge guardrail 3 from the vertical groove 412, and then enter the fine water pipe 406 through the screening of the floor drain sheet 407, and finally merge into the thick water pipe 401 to be drained together;

[0033] At this time, a large amount of rainwater falls rapidly from the thick water pipe 401 from top to bottom. By utilizing the fixed connection between the buffer tube 408 and the fixed shaft 409, and the rotational connection between the fixed shaft 409 and the fan blade 410, the falling rainwater hits the surface of the fan blade 410, and then the fan blade 410 is forced to rotate and push away the rainwater, which can slow down the downward impact of the rainwater, so that the municipal road and bridge drainage device can accurately screen garbage and drain water, and it is not easy to cause water accumulation on the bridge deck 1 when the rainfall is heavy, so as to avoid traffic accidents caused by water accumulation. In addition, the buffer design is used to protect the drainage pipe and increase the service life of the viaduct drainage pipe.

[0034] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
