Description

Technical Field

[0001] This utility model relates to the field of underground drainage technology, specifically to an underground drainage ditch for municipal roads. Background Technology

[0002] Municipal road underground drainage ditches are an important component of urban drainage systems. They primarily refer to underground pipe or ditch systems laid beneath urban roads to collect, transport, and discharge rainwater, sewage, and other liquid waste from roads and surrounding areas. Their primary function is to promptly remove water accumulated on road surfaces during rainfall, ensuring normal passage for vehicles and pedestrians.

[0003] Underground drainage ditches are commonly used in municipal roads. Chinese utility model patent CN219909242U discloses an anti-clogging device for municipal road drainage ditches, relating to the field of drainage ditch technology. It addresses the problem that when water flows into the drainage ditch, it carries away garbage, causing accumulation and blockage, thus affecting drainage efficiency. The device features a screening component in the middle of the channel, and a limiting groove on one side of the channel's inner wall. A cleaning roller is connected to the limiting groove and positioned close to one end of the screening component. The screening component includes a screening plate, a baffle plate, a collection chamber, and toothed grooves. The screening plate is located on one side of the channel's inner wall, the baffle plate is located at the end of the screening plate away from the channel's inner wall, the collection chamber is located on the side of the baffle plate away from the screening plate, and the toothed grooves are located on both sides of the top of the screening plate. This utility model, through its screening component, separates impurities and water flow into different cavities, preventing larger garbage from flowing with the water and accumulating, thus avoiding blockage.

[0004] However, in the process of using this utility model, although the screening plate can filter sewage, when a blockage occurs in a certain section of the drainage ditch, water may accumulate and overflow, which will affect the safety of the municipal road surface and cannot meet the production needs. Therefore, an underground drainage ditch for municipal roads is proposed to solve the problems mentioned above. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides an underground drainage ditch for municipal roads, which has the advantage of improving drainage efficiency. It solves the problem that although screening plates can filter sewage, when a section of the drainage ditch is blocked, water may accumulate and overflow, which will affect the safety of the municipal road surface and fail to meet production needs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an underground drainage ditch for municipal roads, comprising a drainage ditch body and an installation hopper disposed inside the drainage ditch body, wherein the exterior of the drainage ditch body is provided with a tributary drainage structure that can improve drainage efficiency;

[0007] The tributary drainage structure includes an installation box located on one side of the main body of the drainage ditch. A tributary pipe is fixedly installed inside the installation box. A connecting pipe is fixedly connected between the main body of the drainage ditch and the tributary pipe. A connecting rod is fixedly connected between the installation box and the main body of the drainage ditch.

[0008] Furthermore, there are two installation boxes, which are symmetrically distributed on the left and right sides of the main body of the drainage ditch. A drain net is fixedly connected to the inside of the connecting pipe on the side closest to the main body of the drainage ditch.

[0009] Furthermore, the main body of the drainage ditch is composed of a concrete base and an epoxy coating, with the epoxy coating located on the inner wall of the main body of the drainage ditch.

[0010] Furthermore, the interior of the installation hopper is fixedly connected with a filter screen capable of filtering sewage, and a snap-fit ​​structure is provided between the installation hopper and the main body of the drainage ditch.

[0011] Furthermore, the snap-fit ​​structure includes a first spring fixedly connected to the inside of the mounting hopper, and an elastic snap block extending into the body of the first spring is fixedly connected to one end of the first spring near the body of the drainage ditch. The inner wall of the body of the drainage ditch is provided with a mounting hole that matches the elastic snap block.

[0012] Furthermore, a protective cover plate is provided on the upper surface of the main body of the drainage ditch. The interior of the protective cover plate is provided with a drainage hole that communicates with the interior of the main body of the drainage ditch. Positioning plates that are snapped into the main body of the drainage ditch are fixedly connected to both the left and right sides of the protective cover plate.

[0013] Furthermore, an extension block is fixedly connected to the front of the main body of the drainage ditch, and a splicing block extending to its top is slidably connected inside the extension block. A second spring is fixedly connected between the extension block and the splicing block.

[0014] Compared with the prior art, this utility model provides an underground drainage ditch for municipal roads, which has the following beneficial effects:

[0015] 1. The underground drainage ditch of this municipal road is equipped with installation boxes and branch pipes, and then connected by connecting pipes, which facilitates the branching of water flow inside the main body of the drainage ditch into the branch pipes. This can reduce the water flow pressure inside the main body of the drainage ditch. When the main body of the drainage ditch is blocked, water flow from other locations can flow out directly through the branch pipes, thus preventing water overflow.

[0016] 2. This municipal road underground drainage ditch, by installing an inner hopper and a filter screen, can filter sewage. Furthermore, by incorporating a first spring and elastic locking blocks, the inner hopper can be easily installed, improving the practicality of the device. This solves the problem that while screening plates can filter sewage, blockages in certain sections of the drainage ditch can lead to water accumulation and overflow, affecting the safety of the municipal road surface and failing to meet production needs.

The drainage ditch body 1 is provided with a tributary drainage structure that can improve drainage efficiency. The tributary drainage structure includes an installation box 3 installed on one side of the drainage ditch body 1. A tributary pipe 4 is fixedly installed inside the installation box 3. A connecting pipe 5 is fixedly connected between the drainage ditch body 1 and the tributary pipe 4. A connecting rod is fixedly connected between the installation box 3 and the drainage ditch body 1.

[0025] There are two installation boxes 3, which are symmetrically distributed on the left and right sides of the main body of the drainage ditch 1. A drain net is fixedly connected to the inside of the connecting pipe 5 on the side close to the main body of the drainage ditch 1. The main body of the drainage ditch 1 is composed of a concrete base 101 and an epoxy coating 102. The epoxy coating 102 is located on the inner wall of the main body of the drainage ditch 1.

[0026] It should be noted that by setting the epoxy coating 102, the smoothness of the inner wall of the drainage ditch body 1 can be improved, thereby increasing the water flow speed. At the same time, it can also play a certain role in corrosion prevention. By setting the installation box 3 and the branch pipe 4, and by setting the connecting pipe 5, it is convenient to branch the water flow inside the drainage ditch body 1 into the branch pipe 4, thereby sharing some of the water flow pressure inside the drainage ditch body 1. When the drainage ditch body 1 is blocked, the water flow in other places can flow out directly through the branch pipe 4, thereby avoiding water overflow.

[0027] In this embodiment, a filter screen 6 capable of filtering sewage is fixedly connected inside the inner hopper 2. A snap-fit ​​structure is provided between the inner hopper 2 and the main body of the drainage ditch 1. The snap-fit ​​structure includes a first spring 7 fixedly connected inside the inner hopper 2. An elastic locking block 8 extending into the inner part of the first spring 7 is fixedly connected to one end of the first spring 7 near the main body of the drainage ditch 1. An installation hole adapted to the elastic locking block 8 is provided on the inner wall of the main body of the drainage ditch 1.

[0028] The device features an inner hopper 3 and a filter screen 6 for filtering wastewater. The first spring 7 and elastic locking block 8 facilitate the installation of the inner hopper 3, improving the device's practicality. It also allows workers to easily remove the inner hopper 2 for cleaning.

[0029] In this embodiment, a protective cover plate 9 is provided on the upper surface of the main body 1 of the drainage ditch. The interior of the protective cover plate 9 is provided with a drainage hole 10 that communicates with the interior of the main body 1 of the drainage ditch. Positioning plates 11 that are snapped into the main body 1 of the drainage ditch are fixedly connected to both the left and right sides of the protective cover plate 9. An extension block 12 is fixedly connected to the front of the main body 1 of the drainage ditch. A splicing block 13 extending to the top of the extension block 12 is slidably connected inside the extension block 12. A second spring 14 is fixedly connected between the extension block 12 and the splicing block 13.

[0030] The left and right sides of the main body of the drainage ditch 1 are in contact with the opposite sides of the two positioning plates 11, and the back of the main body of the drainage ditch 1 is provided with splicing holes that are compatible with the splicing block 13, which makes it convenient for workers to splice multiple main bodies of the drainage ditch 1 and improves construction efficiency.

[0031] The working principle of the above embodiments is as follows:

[0032] First, the staff places the inner hopper 2 into the main body 1 of the drainage ditch. At this time, the first spring 7 and the elastic block 8 will be squeezed. When the elastic block 8 touches the installation hole, it pops out, and the inner hopper 2 is installed. Then, the protective cover 9 is put on. When the water flows through the protective cover 9 into the main body 1 of the drainage ditch, it will be filtered directly by the filter screen 6 and then discharged through the main body 1 of the drainage ditch.
