Description

Technical Field

[0001] This utility model relates to the field of curb stones, and in particular to a precast concrete curb stone. Background Technology

[0002] Curb stones are used to demarcate the roadway, sidewalk, green space, median strip, and other parts of the road, serving to ensure the safety of pedestrians and vehicles and to maintain the neatness of the road edges. Curb stones are generally made by cutting natural stones or casting concrete, and are used as boundary stones for road edges. Due to the high compressive strength and low price of concrete, precast concrete curb stones have largely replaced natural stone curb stones.

[0003] Currently, most precast concrete curb stones have a solid rectangular structure, which is not only heavy, making it difficult for workers to move and inconvenient for construction, but also because the curb stones are made of impermeable materials, resulting in a large amount of water accumulating on both sides of the road and water at the interface between the road surface and the base layer cannot be drained.

[0004] Therefore, it is necessary to provide a precast concrete curbstone to solve the above-mentioned technical problems. Utility Model Content

[0005] This invention provides a precast concrete curbstone, which solves the problems in the background art.

[0006] To solve the above-mentioned technical problems, the precast concrete curbstone provided by this utility model includes: a curbstone body;

[0007] The top of the curbstone body has a groove, and a permeable plate is fixedly connected inside the groove. The front of the curbstone body has a through groove, and several drainage holes are formed at the bottom of the inner wall of the groove. Positioning grooves are formed on both sides of the top of the curbstone body, and positioning blocks are fixedly connected to both sides of the bottom of the curbstone body.

[0008] Preferably, the through groove is connected to the recess, and the through groove, the recess, and the drain hole form a drainage channel.

[0009] Preferably, the positioning groove is adapted to the positioning block, and the permeable plate is located at two-thirds of the depth of the groove.

[0010] Preferably, the front of the curbstone body is provided with a slope, and an anti-slip layer is provided on the slope.

[0011] Preferably, a splicing groove is provided on the left side of the curbstone body, a splicing block is fixedly connected to the right side of the curbstone body, and a conical block is fixedly connected to the right side of the splicing block.

[0012] Preferably, the splicing groove is adapted to the splicing block.

[0013] Compared with related technologies, the precast concrete curbstone provided by this utility model has the following beneficial effects:

[0014] This utility model provides a precast concrete curbstone. The groove design makes the entire curbstone lightweight, facilitating handling and transportation. After installation, plants can be planted inside the grooves to enhance the landscaping effect. The drainage channel allows water from the road surface to be introduced and then drained into the sewer through the grooves and drainage holes, effectively preventing water accumulation and greatly improving practicality. The water can also be used to irrigate the plants through a permeable plate. The positioning grooves and blocks allow multiple curbstones to be stacked together, improving stability during transportation. During installation, the positioning blocks can be inserted into the roadbed, further enhancing installation stability and preventing the curbstone from collapsing. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please refer to the following: Figure 1 , Figure 2 , Figure 3 ,in, Figure 1 A schematic diagram of a preferred embodiment of the precast concrete curbstone provided by this utility model; Figure 2 for Figure 1 The bottom view of the curbstone shown; Figure 3 for Figure 1 The diagram shows a cross-sectional view of the curbstone body. The precast concrete curbstone includes: the curbstone body 1;

[0021] The top of the curbstone body 1 is provided with a groove 2, and a permeable plate 3 is fixedly connected inside the groove 2. The front of the curbstone body 1 is provided with a through groove 4. Several drainage holes 5 are provided at the bottom of the inner wall of the groove 2. Positioning grooves 6 are provided on both sides of the top of the curbstone body 1. Positioning blocks 7 are fixedly connected to both sides of the bottom of the curbstone body 1.

[0022] The groove 2 allows the curbstone body 1 to be lightweight. After the curbstone body 1 is installed, green plants can be planted inside the groove 2 to improve the greening effect. The green plant base soil is installed on the permeable plate 3, and the road surface water introduced by the channel 4 can also be used for irrigation.

[0023] The through groove 4 is connected to the groove 2, and the through groove 4, the groove 2 and the drain hole 5 form a drainage channel.

[0024] Drainage hole 5 connects to the road sewer, and water on the road surface is introduced through channel 4, and then enters the sewer through groove 2 and drainage hole 5, which improves the drainage effect of the road surface.

[0025] The positioning groove 6 is adapted to the positioning block 7, and the permeable plate 3 is located at two-thirds depth of the groove 2.

[0026] Installing the permeable plate 3 at two-thirds depth of the groove 2 ensures that the green plants can be watered while preventing the water flow from washing away the base soil and reducing erosion.

[0027] The curbstone body 1 has a bevel 8 on its front side, and an anti-slip layer 9 is provided on the bevel 8.

[0028] The slope 8 enhances the protective effect of the curbstone body 1, preventing injury from bumps and knocks. The anti-slip layer 9 further improves the anti-slip effect and enhances safety.

[0029] A splicing groove 10 is provided on the left side of the curbstone body 1, and a splicing block 11 is fixedly connected to the right side of the curbstone body 1. A conical block 12 is fixedly connected to the right side of the splicing block 11.

[0030] By inserting the splicing block 11 into the splicing groove 10, the splicing between two curbstone bodies 1 can be realized, which can achieve integration after installation, greatly reducing the possibility of settlement. Furthermore, splicing can also be carried out during transportation, thereby increasing stability. The conical block 12 facilitates the entry of the splicing block 11 into the splicing groove 10, reducing the difficulty of splicing.

[0031] The splicing slot 10 is adapted to the splicing block 11.

[0032] The working principle of the precast concrete curbstone provided by this utility model is as follows:

[0033] The groove 2 makes the entire curbstone body 1 lighter. After the curbstone body 1 is installed, green plants can be planted inside the groove 2. The channel 4 can introduce road surface water, which is then discharged into the sewer through the groove 2 and the drainage hole 5. The water can also be used to irrigate the green plants through the permeable plate 3. The positioning groove 6 and positioning block 7 allow multiple curbstone bodies 1 to be stacked together, improving stability during transportation.

[0034] Compared with related technologies, the precast concrete curbstone provided by this utility model has the following beneficial effects:

[0035] The groove 2 design makes the entire curbstone body 1 lightweight, facilitating handling and transportation. After installation, greenery can be planted inside the groove 2 to enhance the landscaping effect.
