Description

Technical Field

[0001] This utility model relates to the field of curbstone technology, and in particular to an integrated drainage curbstone. Background Technology

[0002] In municipal road construction, curb stones are used to distinguish the roadway, sidewalk, green belt, median strip, and other parts of the road, playing a role in ensuring the safety of pedestrians and vehicles and ensuring the neatness of the road surface edges.

[0003] Commonly used curb stones are typically made of concrete or marble, forming a stepped structure with upright and flat curb stones. Currently, most curb stones lack drainage functionality. Existing technology includes a curb stone structure that integrates the curb stone and rainwater drainage pipe, with a circular pipe channel structure located beneath the curb stone. This solution achieves drainage modification without requiring separate drainage pipes. However, the drainage pipe channel in this solution is usually located below the road surface level, resulting in a relatively high overall structure formed by the curb stone and drainage pipe. This necessitates excavating deeper trenches during paving construction, increasing the workload and difficulty of the project. To address these shortcomings, this application is proposed. Utility Model Content

[0004] The purpose of this invention is to provide an integrated drainage curbstone, which solves the problems of ordinary curbstones lacking drainage function and the increased construction work caused by the high overall structure of curbstones with drainage function.

[0005] To address the aforementioned problems, this utility model provides an integrated drainage curbstone, comprising a side upright portion and a side flat portion. The top of the side upright portion is higher than the top of the side flat portion. The side flat portion is provided with a main flow channel and an initial flow channel located outside the main flow channel. The side upright portion is provided with an emergency flow channel located inside the main flow channel. The cross-sectional area of ​​the emergency flow channel is smaller than that of the main flow channel. The top surface of the side flat portion is provided with a drain outlet connecting the main flow channel and the initial flow channel. The side upright portion is provided with an emergency drain outlet connected to the emergency flow channel. The height of the emergency drain outlet is higher than the height of the drain outlet.

[0006] By setting multiple flow channels in the curbstone, the drainage function is combined with the curbstone, and the appearance and shape of the curbstone are not significantly changed, and the height of the curbstone is not increased, thus avoiding increased construction volume and difficulty.

[0007] By setting up narrower initial flow channels, the flow velocity of rainwater is increased by utilizing the smaller channel width, reducing the risk of soil siltation at the bottom of the channel and ensuring rapid drainage during light rain or the initial stage of rainfall.

[0008] The main drainage channel is responsible for draining moderate rainfall, while the emergency drainage channel connects to the accumulated water through emergency drainage outlets during heavy rain or severe water accumulation, forming a three-level drainage system (initial → main channel → emergency), which significantly improves the overall drainage capacity and prevents road surface water from overflowing the curbs and entering the sidewalks.

[0009] The initial high-speed water flow in the flow channel reduces siltation, while the emergency flow channel operates independently and is not activated until the set water level is reached. This avoids blockages caused by long-term use, ensures emergency functionality, and extends the service life of the drainage system, thus enabling the curbstone to serve both emergency and daily drainage purposes.

[0010] According to one embodiment of the present invention, one end of the side upright portion and the side flat portion is provided with a docking protrusion, and the other end is provided with a docking groove. Through the standardized docking groove and protrusion structure, modular and rapid installation can be achieved, reducing the complexity of manual operation and improving construction efficiency.

[0011] According to one embodiment of the present invention, the emergency drain outlet is located on the side of the side stand to reduce the probability of blockage of the emergency drain outlet.

[0012] According to one embodiment of the present invention, a connecting part is provided at the upper position between the emergency flow channel and the main flow channel. When the water volume is large, the water in the emergency flow channel enters the main flow channel through the connecting part.

[0013] According to one embodiment of the present invention, the height of the emergency flow channel is greater than the height of the main flow channel, making full use of the internal space of the side support to ensure emergency drainage flow.

[0014] According to one embodiment of the present invention, the top corner of the side stand is provided with an arc structure to reduce the safety hazard of pedestrians bumping into it.

[0015] According to one embodiment of the present invention, the drain outlet adopts an elongated hole, the length direction of which is perpendicular to the extension direction of the main channel and the initial flow channel, which has good drainage performance and aesthetics, and several groups of elongated holes are provided.

[0016] According to one embodiment of the present invention, the emergency drain outlet is a round hole with its center located on the axis of the elongated hole, further ensuring aesthetics.

[0017] The beneficial effects of this utility model are that by setting multiple channels in the curbstone, the drainage function is combined with the curbstone, and the appearance and shape of the curbstone are not significantly changed. There is no increase or significant increase in the height of the curbstone or the external structure, thus avoiding increased construction volume and difficulty. The multi-stage drainage system composed of multiple channels can effectively improve drainage efficiency and reduce the probability of blockage. In particular, by setting a narrower initial channel, the rainwater flow rate is increased by using the smaller channel width, reducing the risk of soil accumulation at the bottom of the channel, ensuring rapid drainage in light rain or at the beginning of rainfall. The emergency channel operates independently and is not activated until the set water level is reached, avoiding blockage problems caused by long-term use, ensuring emergency function, and extending the service life of the drainage system. Thus, the curbstone can serve both emergency and daily drainage purposes. The drainage structure is hidden inside the curbstone, avoiding the damage to the road surface aesthetics caused by traditional drainage ditches, while also reducing the risk of tripping.

[0023] The following description is only intended to disclose the present invention so that those skilled in the art can implement it. The embodiments in the following description are merely examples, and those skilled in the art will conceive of other obvious modifications. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0024]

Example 1

[0025] An integrated drainage curbstone, such as Figures 1-4 It includes a side upright part 1 and a side flat part 2.

[0026] The top of the side stand 1 is higher than the top of the side flat part 2. The side stand and the side flat part together form a stepped structure. During installation, the side stand 1 is generally closer to the sidewalk, and the side flat part 2 is closer to the road.

[0027] The side upright section 1 and the side horizontal section 2 preferably adopt the integral concrete casting process to improve the integrity of the curbstone and the drainage system and reduce the risk of misalignment caused by settlement in traditional split structures.

[0028] One end of the side upright part 1 and the side flat part 2 is provided with a docking protrusion 9, and the other end is provided with a docking groove 8. Through the standardized docking groove and protrusion structure, modular rapid installation can be achieved, reducing the complexity of manual operation and improving construction efficiency.

[0029] The top corner of the side stand 1 is provided with a rounded structure 11 to reduce the safety hazard of pedestrians bumping into it.

[0030] The side section 2 is provided with a main flow channel 5 and an initial flow channel 6 located outside the main flow channel 5. The side section 1 is provided with an emergency flow channel 7 located inside the main flow channel 5. That is, the initial flow channel 6 is located on the side closer to the road, and the emergency flow channel 7 is located on the side closer to the sidewalk. When the water on the road surface flows outward, it will preferentially enter the initial flow channel 6.

[0031] The cross-sectional area of ​​the emergency flow channel 7 is smaller than that of the main flow channel 5. The top surface of the side flat part 2 is provided with a drain outlet 3 connecting the main flow channel 5 and the initial flow channel 6. The side upright part 1 is provided with an emergency drain outlet 4 connected to the emergency flow channel 7. The height of the emergency drain outlet 4 is higher than that of the drain outlet 3, ensuring that emergency drainage is automatically activated when the water accumulation reaches the critical value without manual intervention.

[0032] like Figure 1 , Figure 2 The drain outlet 3 adopts an elongated hole, and several groups of elongated holes are set. They are located at the top of the side flat part 2 and above the main flow channel 5 and the initial flow channel 6. The length direction of the holes is perpendicular to the extension direction of the main flow channel 5 and the initial flow channel 6, which has good drainage performance and aesthetics. The emergency drain outlet 4 adopts a round hole and is set on the side of the side upright part 1 to reduce the probability of blockage of the emergency drain outlet 4. Its center is on the axis of the elongated hole, which further ensures aesthetics.

[0033] A connecting part 10 is provided at the upper part between the emergency flow channel 7 and the main flow channel 5. When the water volume is large, the water in the emergency flow channel 7 enters the main flow channel 5 through the connecting part 10.

[0034] The top height of the emergency flow channel 7 is higher than that of the main flow channel 5, making full use of the internal space of the side section 1 to ensure emergency drainage flow. It can meet the emergency drainage needs without increasing or significantly increasing the height of the curbstone, reducing the burial depth requirements of traditional drainage pipes, reducing the trench excavation depth and earthwork volume, and simplifying the construction process.

[0035] By setting multiple flow channels in the curbstone, the drainage function is combined with the curbstone, and the appearance and shape of the curbstone are not significantly changed, and the height of the curbstone is not increased, thus avoiding increased construction volume and difficulty.

[0036] Multi-stage drainage systems improve drainage efficiency by setting narrower initial flow channels, which increases rainwater flow velocity and reduces the risk of soil siltation at the bottom of the channels, ensuring rapid drainage during light rain or the initial stages of rainfall.

[0037] The main channel is responsible for drainage during moderate rainfall, while the emergency channel connects to the accumulated water through emergency drainage outlet 4 during heavy rain or severe water accumulation, forming a three-level drainage system (initial → main channel → emergency), which significantly improves the overall drainage capacity and prevents road surface water from overflowing the curbs and entering the sidewalk.

[0038] The initial high-speed water flow in the flow channel reduces siltation, while the emergency flow channel operates independently and is not activated until the set water level is reached. This avoids blockages caused by long-term use, ensures emergency functionality, and extends the service life of the drainage system, thus enabling the curbstone to serve both emergency and daily drainage purposes.

[0039] During construction, the device is placed in the trench after excavation. Because the structure has an emergency flow channel in the area below the side upright 1, the total area of ​​the flow channel is increased. In the case of water accumulation on the road surface, it achieves a similar drainage effect as installing a drainage pipe of the same diameter under the road surface, and reduces the overall height.

[0040] When rainfall occurs, during the initial and light rainfall phases, the water on the road surface first flows into the initial flow channel through drain 3. Due to the narrow width of the initial flow channel, the flow velocity is relatively fast under the same rainfall. The faster flow velocity helps reduce soil accumulation at the bottom of the flow channel and reduces the probability of blockage. When the rainfall is heavy, the rainwater enters the main flow channel through drain 3 for drainage. When the rainfall further increases, water accumulates on the road surface. When the water level is higher than the height of emergency drain 4, the water enters the emergency flow channel through emergency drain 4 for discharge, thereby achieving emergency drainage and reducing the possibility of water exceeding the side stones and overflowing the sidewalk.

[0041] This technical solution achieves the comprehensive goals of maximizing drainage efficiency, minimizing construction costs, and improving system durability through a multi-stage drainage system, modular design, and structural optimization. It solves the core problems of complex construction, insufficient drainage capacity, and difficult maintenance of traditional curbstone drainage structures, and has significant engineering application value.

[0042] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations and modifications.
