Description

Technical Field

[0001] The utility model relates to a drainage structure for asphalt roads, specifically a drainage structure for municipal asphalt roads, belonging to the technical field of drainage structures. Background Technique

[0002] Municipal asphalt roads are roads paved with asphalt materials in urban municipal engineering. The drainage of asphalt roads mainly includes three parts: surface drainage of the road surface, internal drainage of the road surface, and subgrade drainage. Among them, surface drainage of the road surface is often achieved by setting drainage wells inside the road, and usually a drainage manhole cover is installed at the rainwater inlet.

[0003] However, traditional drainage manhole covers are usually directly laid above the concrete foundation, and when the road surface is covered with rainwater, they usually drain only through the holes opened above them or the gaps reserved between them and the wellhead. Therefore, when there is waterlogging in the municipal road, the manhole cover is usually directly removed from the wellhead, resulting in the wellhead being suspended. Moreover, it is difficult to distinguish the position of the well water due to the rainwater covering. Therefore, when pedestrians pass above the wellhead, they are likely to fall into the drainage well, posing a safety hazard and easily causing sundries to enter the drainage well through the wellhead, leading to blockage of the internal pipeline, and having poor practicability. Summary of the Invention

[0004] The purpose of the utility model is to provide a drainage structure for municipal asphalt roads to solve the above problems. By setting a grille inside the well ring and driving the grille to move up and down through a knob, when the manhole cover is disassembled or turned up, the grille is flush with the wellhead, effectively preventing pedestrians from falling into the drainage well, and at the same time being able to effectively block sundries from flowing into the drainage well, with strong practicability.

[0005] The utility model realizes the above purpose through the following technical solutions. A drainage structure for municipal asphalt roads includes a well ring, and a filtering structure is installed on the well ring. The filtering structure includes a chute. Three chutes are opened on the inner side of the well ring. Two guide rods are fixedly connected inside the chute. A connecting plate is slidably connected between the two guide rods. The connecting plate is slidably connected with the inner wall of the chute. A grille is fixedly connected between the three connecting plates. The grille is slidably connected with the inner wall of the well ring. A knob is rotatably connected to the well ring. One of the connecting plates is threadedly connected with the knob.

[0006] Preferably, a spring is fixedly connected between the bottom surface of the connecting plate and the inner wall of the chute, and the guide rod penetrates through the spring.

[0007] Preferably, the cross-section of the well ring is in a "convex" shape structure, and the grille is arranged inside the well ring.

[0008] Preferably, the cross-section of the knob is in a "T" shape structure, and a rotating structure is provided on the well ring for cooperation.

[0009] Preferably, the rotating structure includes a rotating shaft, which is fixedly connected to the well ring, and a mounting clip is rotatably connected to the rotating shaft, with a well cover mounted on the mounting clip.

[0010] Preferably, the mounting clip has a U-shaped cross-section, and the mounting clip is fixedly connected to the manhole cover by bolts.

[0011] Preferably, the manhole cover has two through holes, and the diameter of the manhole cover is smaller than the inner diameter of the manhole ring.

[0012] Preferably, the bottom of the well ring is provided with an installation structure, the installation structure includes an adjusting ring, the bottom of the well ring is provided with an adjusting ring, the adjusting ring is provided with an installation groove, and the bottom of the well ring and the installation groove are engaged with each other.

[0013] Preferably, the inner side of the well ring is provided with four stiffening ribs, and the four stiffening ribs are arranged in a circular array.

[0014] The beneficial effects of this utility model are as follows: Three grooves are provided on the inner side of the manhole ring. Two guide rods are fixedly connected inside the grooves, and a connecting plate is slidably connected between the two guide rods. The connecting plate is slidably connected to the inner wall of the groove. A grid is fixedly connected between the three connecting plates, and the grid is slidably connected to the inner wall of the manhole ring. A knob is rotatably connected to the manhole ring, and one of the connecting plates is threadedly connected to the knob. When the manhole is fully open, to prevent pedestrians from falling into the drainage well from the manhole opening, and to prevent debris from the road surface from flowing into the drainage well through the manhole opening, simply rotate the knob on the manhole ring. The knob then drives the connecting plate to slide upward along the guide rods. Since a grid is installed between the three connecting plates, the connecting plate drives the grid to move upward until the upper surface of the grid is flush with the manhole opening. This not only prevents pedestrians from falling into the drainage well from the manhole opening, but also ensures the flatness of the manhole opening, facilitating smooth vehicle passage and improving safety. Simultaneously, the grid effectively blocks debris from entering the drainage well, making it easier for pedestrians to clean it. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5As shown, a municipal asphalt road drainage structure includes a manhole ring 1, on which a filter structure 3 is installed. The filter structure 3 includes a chute 301. Three chute 301s are formed on the inner side of the manhole ring 1. Two guide rods 302 are fixedly connected inside each chute 301. A connecting plate 303 is slidably connected between the two guide rods 302. The connecting plate 303 is slidably connected to the inner wall of the chute 301. A grid 30 is fixedly connected between the three connecting plates 303. 6. The grille 306 is slidably connected to the inner wall of the well ring 1. A knob 305 is rotatably connected to the well ring 1. One of the connecting plates 303 is threadedly connected to the knob 305. A spring 304 is fixedly connected between the bottom surface of the connecting plate 303 and the inner wall of the slide groove 301. The guide rod 302 passes through the spring 304. The cross-section of the well ring 1 is convex. The grille 306 is located inside the well ring 1. The cross-section of the knob 305 is T-shaped. The well ring 1 is equipped with a rotating structure 4. When the well opening is fully open, to prevent pedestrians from falling into the drainage well and to prevent debris from the road from flowing into the drainage well, simply rotate the knob 305 on the well ring 1. The knob 305 then drives the connecting plate 303 to slide upward along the guide rod 302. Since a grille 306 is installed between the three connecting plates 303, the connecting plates 303 drive the grille 306 to move upward until the upper surface of the grille 306 is flush with the well opening. This not only prevents pedestrians from falling into the drainage well but also ensures the flatness of the well opening, facilitating smooth vehicle passage and improving safety. At the same time, the grille 306 can effectively block debris from entering the drainage well, making it easy for pedestrians to clean. In addition, since a spring 304 is provided between the connecting plate 303 and the inner wall of the chute 301, the connecting plate 303 slides to the top under the elastic force of the spring 304, which facilitates the subsequent installation of the grille 306 and improves operational efficiency.

[0023] As a technical optimization of this utility model, the rotating structure 4 includes a rotating shaft 401, which is fixedly connected to the manhole ring 1. A mounting clip 402 is rotatably connected to the rotating shaft 401, and a manhole cover 403 is mounted on the mounting clip 402. The mounting clip 402 has a U-shaped cross-section. The mounting clip 402 and the manhole cover 403 are fixedly connected by bolts 404. The manhole cover 403 has two through holes 405, and its diameter is smaller than the inner diameter of the manhole ring 1. When the municipal asphalt road experiences flooding, the through holes 405 on the manhole cover 403... The two through holes 405 are no longer sufficient to meet the current drainage needs. Therefore, in order to improve the drainage effect of the drainage well, the well cover 403 on the well ring 1 needs to be flipped up so that the well opening is fully opened. Simply insert a finger into one of the through holes 405 and pull the well cover 403 upward. At this time, the well cover 403 drives the mounting clip 402 to rotate around the rotating shaft 401 until the well cover 403 is fully flipped up, thereby fully opening the well opening and enhancing the drainage effect. At the same time, since the well cover 403 and the mounting clip 402 are fixedly connected by bolts 404, it is easy to quickly replace the well cover 403 when it is damaged, which is highly flexible.

[0024] As a technical optimization of this utility model, the bottom of the manhole ring 1 is provided with an installation structure 2, the installation structure 2 including an adjusting ring 201. The bottom of the manhole ring 1 is provided with an adjusting ring 201, and an installation groove 203 is opened on the adjusting ring 201. The bottom of the manhole ring 1 and the installation groove 203 are engaged with each other. Four stiffening ribs 202 are opened on the inner side of the manhole ring 1, and the four stiffening ribs 202 are arranged in a circumferential array. Since the bottom of the manhole ring 1 is engaged in the installation groove 203 on the adjusting ring 201 when the manhole ring 1 is installed, the stability is strong. The setting of the adjusting ring 201 can adjust the height of the manhole cover 403 to make it flush with the road surface, and can also distribute pressure and enhance the sealing performance. The stiffening ribs 202 on the adjusting ring 201 can improve the load-bearing capacity of the manhole cover 403.

[0025] When this utility model is in use, if the municipal asphalt road experiences flooding, the two through holes 405 on the manhole cover 403 are insufficient to meet the drainage needs. To improve the drainage effect, the manhole cover 403 on the manhole ring 1 needs to be flipped up to fully open the manhole. Simply insert a finger into one of the through holes 405 and pull the manhole cover 403 upwards. The manhole cover 403 will then drive the mounting clip 402 to rotate around the pivot 401 until the manhole cover 403 is fully flipped up, thus fully opening the manhole and enhancing the drainage effect. Since the manhole cover 403 and the mounting clip 402 are fixedly connected by bolts 404, it is easy to quickly replace the manhole cover 403 if it is damaged, offering high flexibility. When the manhole is fully open, to prevent pedestrians from falling into the drainage well and to prevent debris from the road surface from flowing into the drainage well, simply rotate the knob 305 on the manhole ring 1. The knob 305 will then drive the connecting plate 303 to slide upwards along the guide rod 302. A grille 306 is installed between the connecting plates 303. The connecting plates 303 then move the grille 306 upwards until its upper surface is flush with the manhole opening. This not only prevents pedestrians from falling into the drainage well but also ensures the flatness of the manhole opening, facilitating smooth vehicle passage and improving safety. Simultaneously, the grille 306 effectively blocks debris from entering the drainage well, making it easy for pedestrians to clean. Furthermore, a spring 304 is installed between the connecting plates 303 and the inner wall of the chute 301. Then, under the elastic force of the spring 304, the connecting plate 303 slides to the top, which facilitates the subsequent installation of the grid 306, resulting in high operational efficiency. Furthermore, since the bottom of the manhole ring 1 is engaged in the mounting groove 203 on the adjusting ring 201 when the manhole ring 1 is installed, it has strong stability. The adjusting ring 201 can adjust the height of the manhole cover 403 to make it flush with the road surface, and can also distribute pressure and enhance sealing. In addition, the stiffening ribs 202 on the adjusting ring 201 can improve the load-bearing capacity of the manhole cover 403.
