Description

Technical Field

[0001] This utility model belongs to the field of highway drainage technology, and in particular relates to a highway curb drainage node. Background Technology

[0002] Curbstones are marker stones placed between the road surface and other structures. They are also called curb stones or roadside stones. Curbstones clearly delineate the boundaries between different areas such as the road surface, shoulder, sidewalk, green belt, and slope, and define the effective use range of the road. Road drainage is closely related to curbstones and is a key link to ensure the normal use of the road and extend its life.

[0003] Highway drainage typically relies on drainage wells installed at regular intervals. However, during extreme weather events such as heavy rainfall, large amounts of rainwater rapidly accumulate, and the limited number of drainage outlets cannot effectively and promptly remove the water, leading to severe road flooding. Furthermore, water pools near the curbs, hindering vehicle traffic and potentially causing accidents. Therefore, a new type of highway curb drainage node is needed. This node utilizes precast buried pipes and hollow curbs as drainage channels, increasing the number of drainage points and enabling rapid removal of road flooding. It also incorporates easy-to-maintain filtration and cleaning structures, ensuring optimal drainage capacity with regular maintenance. Utility Model Content

[0023] In the following description, embodiments of the road curb drainage node of the present invention will be described with reference to the accompanying drawings.

[0024] Figure 1-5This invention illustrates a road curb drainage node according to an embodiment of the present invention, comprising a precast buried pipe 1: the precast buried pipe 1 is laid in the roadbed on one side of the road, a hollow curb stone 2 is engaged at the top of the precast buried pipe 1, upper grooves 9 are provided on both sides of the top of the precast buried pipe 1, lower grooves 10 adapted to the upper grooves 9 are provided on both sides of the bottom of the hollow curb stone 2, multiple low water level drainage holes 3 are provided on the right side of the hollow curb stone 2, multiple high water level drainage holes 8 are provided on the top of the right side of the hollow curb stone 2, and a... Inspection port 4, with a cover plate 5 engaging inside the cavity of inspection port 4. Locking components 6 are provided on the front and rear sides of the top of the hollow curbstone 2. Locking components 6 include a fixing sleeve 61 fixedly connected to the top of the hollow curbstone 2. A rotating component 62 is rotatably connected to the inner cavity of the fixing sleeve 61. A limit clamp 63 is fixedly connected to the bottom surface of the rotating component 62. Limiting slots 64, adapted to the limit clamp 63, are provided on the front and rear sides of the cover plate 5. A plastic tensioning sleeve is fixedly connected to the surface of the rotating component 62. The inner wall of the fixing sleeve 61 is connected to the plastic tensioning sleeve. Through the locking assembly 6, the rotating part 62, the limiting clip 63, and the limiting slot 64 work together to limit and lock the cover plate 5, allowing the cover plate 5 to be stably placed in the inner cavity of the inspection port 4. Simultaneously, with the cooperation of the plastic tension sleeve on the surface of the rotating part 62, the limiting clip 63 will not shift under external force after entering the inner cavity of the limiting slot 64, thereby further improving the limiting strength of the cover plate 5. The inner cavity of the prefabricated buried pipe 1 is equipped with a filter assembly 7, which includes... The filter plate 71 is located inside the prefabricated buried pipe 1. Bolts 72 are fixedly connected to the front and rear ends of both sides of the prefabricated buried pipe 1. Nuts 74 are threaded onto the surface of the bolts 72. Hanging holes 73 that are compatible with the bolts 72 are opened at the front and rear ends of both sides of the bottom of the filter plate 71. The nuts 74 are tightly pressed into the inner wall of the filter plate 71. With the cooperation of the bolts 72, hanging holes 73 and nuts 74, the filter plate 71 can be stably installed in the inner cavity of the prefabricated buried pipe 1, and at the same time, it is convenient for users to disassemble and clean it.

[0025] Working principle: When using this utility model, the user lays the precast buried pipe 1 and hollow curbstone 2 on one side of the road, and lays a certain number according to the length of the road. When rainwater appears on the road, the rainwater enters the inner cavity of the hollow curbstone 2 from the inner cavity of the low water level drainage hole 3, passes through the water leakage holes on the surface of the filter plate 71, and enters the inner cavity of the precast buried pipe 1 for drainage. If the drainage speed of the low water level drainage hole 3 cannot meet the drainage needs of the retaining wall, the water level on the road surface rises and reaches the high water level drainage hole 8 for secondary drainage, thereby controlling the road water accumulation within a certain range. During drainage, the water level rises and reaches the high water level drainage hole 8 for secondary drainage, thus controlling the road water accumulation within a certain range. The filter plate 71 can block debris from entering the cavity of the precast buried pipe 1 and the hollow curbstone 2, preventing blockage of the cavity of the precast buried pipe 1 or the hollow curbstone 2. During regular maintenance, the user uses a hexagonal sleeve to rotate the rotating part 62. When the rotating part 62 rotates in the cavity of the fixed sleeve 61, it will drive the limiting clip 63 to rotate, thereby causing the limiting clip 63 to disengage from the cavity of the limiting clip 64, so that the cover plate 5 can be released from the limit. At this time, the cover plate 5 can be removed, and the debris in the cavity of the precast buried pipe 1 and the hollow curbstone 2 can be cleaned through the inspection port 4.

[0026] In summary, this road curb drainage node, through the combined use of hollow curbstone 2, low-water-level drainage hole 3, and high-water-level drainage hole 8, collects the accumulated water that gathers on one side of the road. Then, the collected water is centrally drained away through prefabricated buried pipe 1. Users can open the cover plate 5 to expose the inspection port 4, thereby performing regular maintenance on the inside of the prefabricated buried pipe 1. This achieves the purpose of preventing water from accumulating in one place, accelerating rainwater drainage, and facilitating maintenance and cleaning.
