Description

Technical Field

[0001] This utility model relates to the field of road engineering technology, specifically to a socket-type drainage curb. Background Technology

[0002] Curbstones are an indispensable ancillary facility in urban road engineering. Their main functions are to define the boundaries of the carriageway, ensure pedestrian safety, guide road drainage, and enhance the aesthetics of the road.

[0003] Traditional curb stones are typically rectangular precast components, with adjacent curb stones connected by a planar butt joint. This structure has significant drawbacks: First, the planar joint relies solely on mortar bonding, failing to create effective mechanical interlocking, resulting in each curb stone acting as a self-contained unit with poor overall integrity. When subjected to lateral forces from vehicle impacts, pedestrian trampling, or plant root growth, it is highly susceptible to localized tilting, misalignment, and breakage, not only affecting the road's aesthetics but also posing safety hazards.

[0004] Secondly, with the deepening of the "sponge city" construction, sunken green spaces are widely used in roadside green belts. This type of design results in the curb stones being backed by green spaces instead of traditional backfill soil, causing them to lose effective support from the soil behind them, further weakening their anti-overturning stability.

[0005] Furthermore, the drainage function of traditional curb stones relies on the gaps between them and the road surface, resulting in low drainage efficiency and easy clogging by debris. To effectively channel rainwater from the road surface into sunken green spaces, it is usually necessary to create additional openings or install independent drainage grates, increasing construction complexity and cost, and disrupting the overall integrity and continuity of the curb stone's appearance. Utility Model Content

[0006] The purpose of this utility model is to provide a socket-type drainage curb to solve the problems of insufficient overall stability, low drainage efficiency, and incompatibility with sponge city facilities.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A socket-type drainage curbstone includes several curbstone bodies disposed along the length of the road structure on the side of the road structure. The curbstone bodies are precast components integrally molded from cement concrete. One end of each curbstone body is provided with an outwardly protruding tenon, and the other end is provided with an inwardly recessed slot that matches the shape of the tenon. Two adjacent sets of curbstone bodies are connected to each other through the tenon and the slot. A drainage groove penetrating the width direction is opened in the middle of each curbstone body, and the bottom height of the drainage groove is lower than the road surface height of the adjacent side of the road structure.

[0008] Preferably, the curbstone body has a triangular support cast on the back of the side facing the road, and the other side facing the green belt is covered with backfill gravel or planting soil.

[0009] Preferably, the cross-sections of the tenon and the slot are both trapezoidal or rectangular.

[0010] Preferably, the connecting edge between the top surface of the curbstone body and the side near the road surface structure is a rounded chamfer.

[0011] Preferably, the joint between two adjacent sets of curbstone bodies is filled with cement mortar for grouting.

[0012] Preferably, the curbstone body has a length of 500mm-1000mm, a height of 200mm-300mm, and a width of 150mm-250mm.

[0013] By adopting the above technical solution, this utility model has the following advantages compared with the prior art: This utility model provides a socket-type drainage curbstone. The entire curbstone is a precast concrete component. By setting a tenon at one end and a matching socket at the other end, adjacent curbstones form a tight mortise and tenon mechanical connection during installation, thus connecting the individual curbstone bodies into a continuous organic whole, which can effectively disperse and resist local impact forces from the lateral direction. The drainage groove opened in the middle of the curbstone body has a bottom height lower than the road surface, which can efficiently collect rainwater runoff from the road surface. The drainage function is directly integrated into the curbstone itself, realizing the integration of structure and drainage. There is no need to set up a separate drainage outlet or install additional drainage facilities. The construction is simple and the drainage path is direct and smooth. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] It should be noted that in this utility model, the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element of this utility model must have a specific orientation, and therefore should not be construed as a limitation of this utility model. Example

[0017] Please refer to Figures 1 to 2 As shown, this utility model discloses a socket-type drainage curbstone. The curbstone body 1 is a prefabricated component made of C30 cement concrete through integral molding. Its standard dimensions are: length of 500mm-1000mm, height of 200mm-300mm, and width of 150mm-250mm.

[0018] In this example, the length L = 1000mm, the height H = 250mm, and the width W = 200mm. Multiple curbstone bodies 1 are sequentially installed along the length of the road structure 5 on the side of the road surface.

[0019] One end of the curbstone body 1 has an outwardly protruding tenon 2, and the other end has an inwardly recessed slot 3. Both the tenon and the slot have trapezoidal or rectangular cross-sections. In this embodiment, the cross-sections of the tenon 2 and the slot 3 are preferably trapezoidal. This shape facilitates insertion and creates a self-locking effect after connection, effectively resisting vertical displacement and lateral torsion. Adjacent sets of curbstone bodies 1 achieve a tight mortise and tenon connection by inserting the tenon 2 of one into the slot 3 of the other, thereby connecting multiple independent units into a continuous, impact-resistant whole.

[0020] A drainage channel 4, running the entire width of the curbstone body 1, is mechanically excavated in the middle. The cross-section of the drainage channel 4 is arc-shaped, with its opening facing the top surface of the curbstone and the side closest to the road. It is particularly important to emphasize that the bottom of the drainage channel 4 must be lower than the road surface of the adjacent road structure 5, thus creating an effective height difference. This ensures that rainwater can smoothly flow into and through the drainage channel 4 using gravitational potential energy, and is ultimately guided to the sunken green space or drainage system on the other side, achieving efficient drainage.

[0021] To ensure the curbstone has extremely high anti-overturning stability after installation, especially when backed by a sunken green space, a triangular support structure made of C25 concrete is poured on the back of the curbstone body 1 on the side facing the road. This triangular support structure is firmly integrated with the back of the curbstone and the foundation, providing crucial lateral support. On the other side of the curbstone facing the green belt, graded crushed stone (forming a blind drain to facilitate water infiltration) or planting soil (for landscaping) is backfilled according to design requirements.

[0022] In addition, all connecting edges on the top surface of the curbstone and the side closest to the road surface structure are machined with a 10mm radius rounded chamfer. This design eliminates sharp edges, improves public safety and the product's aesthetics, and reduces the risk of damage to the edges during transportation and installation.

[0023] During installation, the joints between adjacent sets of curbstone bodies 1 should be thoroughly grouted with M10 cement mortar. This not only effectively seals the joints and prevents rainwater from seeping into and eroding the base layer, but also further enhances the stability and continuity of the overall structure.

[0024] The construction process of this utility model is as follows: Basic preparation: On the compacted and leveled road base, excavate the foundation trench according to the design elevation and position, then pour the C15 plain concrete cushion layer, and level and compact it.

[0025] First piece installation: Hoist the first curbstone into place and use measuring tools to precisely adjust its elevation, design alignment, and verticality.

[0026] Sequential insertion: Align the slot 3 of the second curbstone with the tenon 2 of the already installed curbstone, and press it vertically downwards to ensure a tight and proper fit between the tenon and mortise. Repeat this process to install the remaining curbstones in sequence, forming a neat linear array.

[0027] Back support construction: Install formwork on the back of the already installed curbstone array on the side facing the road, and then pour C25 concrete to form a continuous and sturdy triangular support.

[0028] Backfilling on the other side: On the side of the curbstone array closest to the green belt, backfill with graded crushed stone or planting soil according to the design requirements and compact it.

[0029] Joint treatment: All socket joints are sealed with cement mortar.

[0030] Road paving: Finally, the asphalt surface layer of the road is paved to ensure a smooth and seamless connection between the road surface and the groove of the curb drainage channel.

[0031] The above are merely preferred embodiments of this utility model, but the scope of protection 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 scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope of the claims.
