Description

Technical Field

[0001] This utility model relates to the field of highway facilities, specifically to a highway curbstone splicing structure with drainage function. Background Technology

[0002] As the dividing components between the road surface and the roadside green belt and sidewalk, the road curb not only serves to define the road boundary and guide traffic flow, but also needs to undertake a certain drainage function to prevent water accumulation on the road surface from affecting traffic safety.

[0003] Traditional road curbs are mostly single concrete blocks, which are simply stacked or bonded with mortar during splicing. Since there are no dedicated drainage channels, rainwater easily accumulates at the junction of the road surface and the curb. Long-term water accumulation will erode the road base, causing the road surface to crack and become sandy, while also affecting the safety of pedestrians and vehicles. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solution: This utility model provides a road curb splicing structure with drainage function, including a curb body, a drainage pipe at the top of the curb body, a waterproof layer on the inner wall of the drainage pipe, and interlocking blocks and slots on the front and rear surfaces of the curb body. The blocks are interlocked with the slots on adjacent curb bodies. A vertical plate is provided on one side of the width of the curb body, and a grid plate for covering the opening of the drainage pipe is movably connected to the top of the vertical plate.

[0006] Preferably, the drain pipe includes an upper water guide and a bottom drain located at the bottom of the upper water guide, the width of the upper water guide decreasing from top to bottom, and the bottom of the drain pipe having an arc shape that curves downward in the middle.

[0007] Preferably, the connection between the bottom drain and the upper water guide is a rounded transition.

[0008] Preferably, the insert is made of metal and is integrally formed with the curb body.

[0009] Preferably, the upright plate is provided with a stiffening plate on the side facing the curb body, the stiffening plate extends along the length direction of the upright plate, and the stiffening plate is provided with ribs extending into the interior of the curb body.

[0010] Preferably, the grating is made of metal and the vertical plate is made of concrete.

[0011] Preferably, the grating plate is rotatably connected to the vertical plate.

[0012] Preferably, the bottom surface of the grating plate is provided with a slot that fits with the upper water guide opening.

[0013] The beneficial effects are: In this device, rainwater on the road surface can be efficiently collected and quickly discharged through the drainage pipe, effectively preventing water accumulation on the road surface from affecting traffic safety; A waterproof layer can prevent rainwater from penetrating into the curbstone, thus avoiding damage to the curbstone itself due to long-term water erosion and extending its service life.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] First embodiment: See Figures 1-2As shown, this utility model provides a road curb splicing structure with drainage function, including curb body 1, with a drainage pipe 101 on the top of the curb body 1, and a waterproof layer 2 on the inner wall of the drainage pipe 101. The waterproof layer 2 can effectively block the rainwater infiltration path, greatly improve the water erosion resistance of the curb body 1, and extend the service life of the entire curb structure. To ensure the overall stability of the multiple curb body 1 after splicing, the front and rear surfaces of the curb body 1 are respectively provided with interlocking blocks 102 and slots. When installing and splicing the curb stones, the blocks 102 on one curb body 1 are precisely inserted into the slots of the adjacent curb body 1, which can quickly realize the positioning and connection of the two curb bodies 1. The operation is convenient and can also significantly reduce the gaps at the splicing of the curb bodies 1, prevent rainwater from seeping into the roadbed through the gaps, and thus protect the stability of the highway foundation structure. The upright plate 3 installed on one side of the width of the curb body 1 can, on the one hand, provide lateral support to the curb body 1, enhance the overall structural strength of the curb stone, and prevent the curb body 1 from tilting or being damaged due to lateral force; on the other hand, the grid plate 5 movably connected to the top of the upright plate 3 can effectively cover the opening of the drainage pipe 101, which can prevent fallen leaves, gravel, garbage and other debris from entering the drainage pipe 101, prevent the drainage pipe 101 from becoming blocked, and ensure the long-term stable operation of the drainage system.

[0019] In addition, the insert 102 is made of metal, which ensures that the insert 102 is not easily deformed or broken during long-term use, further improving the reliability of the structure. The insert 102 and the curb body 1 are integrally formed, so that the insert 102 and the curb body 1 form a strong connection structure, preventing the insert 102 from separating from the curb body 1 during use, and ensuring the stable realization of the splicing function.

[0020] The second embodiment differs from the first embodiment in that: The drainage pipe 101 includes an upper water guide 101b and a bottom drainage 101a located at the bottom of the upper water guide 101b. The bottom drainage 101a is located at the bottom of the upper water guide 101b, and the bottom drainage 101a and the upper water guide 101b are interconnected, forming a complete drainage channel together. The upper water guide 101b adopts a structure with its width decreasing from top to bottom, which can guide rainwater to quickly converge to the bottom drainage 101a at the bottom and prevent rainwater from stagnating in the upper water guide 101b. At the same time, the bottom of the drainage pipe 101 is an arc shape that bends downward in the middle. The arc structure can not only reduce the resistance when rainwater flows, but also accelerate the downward discharge of rainwater by using gravity, further improving the overall drainage speed and ensuring that the water on the road can be quickly cleared. To completely block rainwater infiltration paths and ensure the long-term durability of drainage pipe 101 and curb body 1, a waterproof layer 2 is laid on the inner walls of both bottom drainage 101a and upper water guide 101b. The waterproof layer 2 structure covering the entire channel can effectively prevent rainwater from seeping through the inner wall of upper water guide 101b when it flows through it, and can also prevent rainwater from eroding the pipe wall when it flows in bottom drainage 101a. This completely solves the seepage problem caused by the lack of local protection, extends the service life of drainage pipe 101, and protects the internal structure of curb body 1 from water erosion damage. The connection between the bottom drain 101a and the upper guide 101b is rounded to prevent rainwater from swirling or stagnating due to the impact of water flow on the corners. This ensures that rainwater can smoothly transition from the upper guide 101b to the bottom drain 101a. On the other hand, the rounded structure can disperse the stress at the connection, preventing cracks from forming at the connection due to water flow impact, temperature changes, and other factors after long-term use. This improves the overall stability and damage resistance of the drain pipe 101.

[0021] The third embodiment differs from the first embodiment in that: To further enhance its structural strength and load-bearing stability, a stiffening plate 4 is provided on the side of the upright plate 3 facing the curb body 1. The stiffening plate 4 extends along the length of the upright plate 3, which can provide continuous support and reinforcement for the longer upright plate 3. The stiffening plate 4 is a high-strength concrete structure. Since the stiffening plate 4 is closer to the road after installation, it can better protect the curb body 1 inside the device when a vehicle accidentally scrapes it or a pedestrian collides with it, preventing the upright plate 3 from bending, deforming or even breaking due to concentrated force, and ensuring the long-term stability of the support function of the upright plate 3. To ensure a stronger connection between the stiffening plate 4 and the curb body 1, a rib 401 extending into the interior of the curb body 1 is provided on the stiffening plate 4. The rib 401 is formed inside the curb body 1 and is made of metal, which allows the rib 401 to be tightly integrated with the internal structure of the curb body 1. When the upright plate 3 and the stiffening plate 4 are subjected to external forces, the external forces can be evenly transferred to the interior of the curb body 1 through the rib 401, avoiding stress concentration only on the connection surface between the stiffening plate 4 and the curb body 1, further reducing the risk of local damage, and making the supporting function of the upright plate 3 more reliable and durable.

[0022] The fourth embodiment differs from the first embodiment in that: In this curbstone splicing structure, the grating plate 5 is made of metal. Metal has high structural strength and wear resistance, which can support vehicles and pedestrians, extend the service life of the grating plate 5, and ensure that it plays a long-term stable role in covering and protecting the opening of the drainage pipe 101. The vertical plate 3 is made of concrete, and the grating plate 5 is connected to the vertical plate 3 by rotation. When it is necessary to clean or repair the inside of the drainage pipe 101, the staff can directly flip the grating plate 5 upward without disassembling the grating plate 5, which is simple and efficient. After the repair is completed, the grating plate 5 can be flipped back to cover the opening of the drainage pipe 101 again, which effectively reduces the difficulty and workload of maintenance operations.

[0023] In addition, a slot is specially provided on the bottom surface of the grating plate 5 to fit with the opening of the upper water guide 101b. This slot can position the grating plate 5 in the reset position, ensuring that after the grating plate 5 is flipped and reset, it can accurately cover the opening of the upper water guide 101b. At the same time, the "gap fit" method not only ensures the fit between the grating plate 5 and the opening of the upper water guide 101b, but also reserves appropriate space for the flipping operation of the grating plate 5.

[0024] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
