Description

Technical Field

[0001] This utility model relates to the field of road paving technology, specifically to a combined structure of roadbed and curbstone. Background Technology

[0002] A curbstone is a marker stone placed between the road surface and other structures, usually located at the edge of the central median, the right edge of the driving lane, or the outer edge of the shoulder.

[0003] According to the public announcement number: CN208733434U, the public announcement date: 2019-04-12, a road curbstone structure based on an integral groove mold was disclosed.

[0004] In the prior art, including the aforementioned patents, since curb stones are usually rectangular prisms or irregular columns of uniform size rather than having a certain curvature, when encountering a curved section of the roadbed during the laying of curb stones, there will inevitably be triangular gaps between adjacent curb stones arranged along the curvature. These gaps also exacerbate the drainage of water from the road surface. When the water flows through the gaps, it carries the roadbed soil below the back of the curb stone, preventing the rainwater from being dispersed over a large area and slowly absorbed by the ground soil. This increases the burden on the local soil to absorb water, causing serious soil erosion, and may even lead to the collapse of this section of the curb stone, affecting the normal use of the curb stone.

[0023] The cushion stone 3 is provided with an upper edge cover 32 for blocking the gap between adjacent curbstones 2, and the curbstone 2 is provided with a drainage channel 23 matched with the middle part of the cushion stone 3.

[0024] Specifically, the roadbed 1 and its laying mode are prior art, which will not be repeated here, the curbstone 2 is arranged in an array at the edge of the roadbed 1, and the edge of the roadbed 1 is arc-shaped.

[0025] Further, after the assembly opening 22 is installed with the cushion stone 3, the upper surface of the cushion stone 3 is flush with the upper surface of the curbstone 2, so that the curbstone 2 is used normally in combination with the cushion stone 3, the drainage channels 23 on each curbstone 2 have the same inclination angle, and the array-arranged drainage channels 23 are connected at the head and tail, so that the drainage channels 23 flow down the accumulated water until reaching the position of the sewer grid on the roadbed 1, facilitating the centralized discharge of excess accumulated water.

[0026] By placing the cushion stone 3 into the assembly opening 22 at the end of the adjacent curbstone 2, the vertical upper edge cover 32 of the cushion stone 3 blocks the gap, so that the accumulated water on the roadbed 1 is not easy to flow from the gap to the back of the curbstone 2, effectively solving the problem of local soil erosion on the back of the curbstone 2 caused by accumulated water through the gap, greatly reducing the soil loss, and during the process of the accumulated water above the upper edge cover 32 flowing to the back of the curbstone 2, the excess accumulated water is diverted into the drainage channel 23 on the curbstone 2, and then the drainage channel 23 is inclined to the sewer grid drainage position, so that the diverted rainwater is concentrated and discharged to the sewer, reducing the problem of excessive erosion of the soil on the back of the curbstone 2 caused by accumulated water, making the soil on the back of the curbstone 2 more stable, and ensuring the normal use of the curbstone 2.

[0027] As a further embodiment of the utility model, the end of the curbstone 2 is provided with a horizontal protrusion 21, and the cushion stone 3 is further provided with a lower edge cover 31 combined with the horizontal protrusion 21.

[0028] Specifically, the horizontal protrusion 21 is a protrusion on the side wall of the curbstone 2, and the length of the horizontal protrusion 21 is greater than the length of the assembly opening 22, so that the excess part can be flush with the lower edge cover 31.

[0029] The lower cover edge 31 and the horizontal protrusion 21 are leveled by the installed cushion stone 3, so that the end faces of the two can be connected with the edge of the roadbed 1, the laying difficulty of the roadbed 1 is reduced, and the cushion stone 3 is in a laid-down "Z" shape due to the lower cover edge 31 and the upper cover edge 32, so that the connecting contact surface and the corner of the cushion stone 3 and the assembling opening 22 are increased, the cushion stone 3 and the curb stone 2 are not easy to separate, and the use stability of the curb stone 2 is increased.

[0030] As further provided by the utility model, a drainage surface 221 is arranged in the assembling opening 22 and matched with the lower cover edge 31.

[0031] Specifically, the drainage surface 221 is an inclined surface on the end face of the assembling opening 22, and the inclined surface is directed to the ground below the curb stone 2, and the drainage area formed by the length of the end of the drainage surface 221 is much larger than the gap between the adjacent curb stones 2.

[0032] The accumulated water seeps into the assembling opening 22 from the side edge of the cushion stone 3, so that the accumulated water flows to the ground through the drainage surface 221, and the ground is provided with sufficient absorption area during the flowing process, so that the problem of soil loss caused by the flowing of rainwater to a certain position of the ground is reduced.

[0033] As further provided by the utility model, a drainage hole 231 is arranged on the curb stone 2 and communicated with the drainage channel 23, and the drainage hole 231 is matched with the horizontal protrusion 21.

[0034] Specifically, the obliquely arranged drainage hole 231 is located at the upside of the upside-down "L" shaped curb stone 2, so that the drainage hole 231 can drain the excess accumulated water.

[0035] When the precipitation enters the gap between the adjacent curb stones 2 or the accumulated water on the top of the curb stone 2 flows along the side wall thereof, the rainwater enters the drainage channel 23 and is used to assist in draining the rainwater, and the rainwater can also be branched through the drainage hole 231 and flow to the upper surface of the curb stone 2, so that the rainwater can be concentrated and drained to the sewer through the surface of the roadbed 1, and the drainage effect of the curb stone 2 is improved.

[0036] As further provided by the utility model, a first inclined surface 33 and a second inclined surface 34 are arranged on the upper cover edge 32 and oppositely arranged, and the first inclined surface 33 is matched with the drainage surface 221.

[0037] Specifically, the first inclined surface 33 is located at the surface of the cushion stone 3 impacted by the rainwater, and the second inclined surface 34 is accommodated in the assembling opening 22.

[0038] The first inclined surface 33 is accommodated in the assembling opening 22 in the default state, so that the first inclined surface 33 can block the rainwater from seeping into the assembling opening 22, the internal environment of the assembling opening 22 is less affected by the accumulated water in the weather with small rainfall, and the use stability of the cushion stone 3 is improved.

[0039] As further provided by the utility model, the assembly opening 22 is internally provided with a drainage gap 24 matched with the second inclined surface 34.

[0040] Specifically, when the adjacent curb stones 2 are arranged in an arc shape, the columnar abutments 3 extend from the assembly openings 22 at both ends, and each part forms a drainage gap 24 inside the assembly opening 22 for converging rainwater drainage.

[0041] In heavy rain, rainwater flows downward from the top of the curb stone 2 and reaches the position of the upper cover edge 32, and the rainwater is divided into two parts through the first inclined surface 33 and the second inclined surface 34, so that a large amount of rainwater flows through the surface of the abutment 3 and is sent to the sewer, and a small amount of rainwater enters the drainage gap 24 through the second inclined surface 34, so that the drainage gap 24 plays a role in dividing rainwater, and the rainwater collected in the drainage gap 24 flows to the ground through the drainage surface 221, so that the roadbed 1 can quickly drain rainwater before waterlogging occurs, and the roadbed 1 can reduce the burden on the soil when dealing with large-area waterlogging, and ensure the recovery ability of the soil under the curb stone 2.

[0042] Working principle: by placing the abutment 3 into the assembly opening 22 at the end of the adjacent curb stone 2, the vertical upper cover edge 32 on the abutment 3 shields the gap, so that the water on the roadbed 1 is not easy to flow from the gap to the back of the curb stone 2, effectively solving the problem of local erosion of the soil on the back of the curb stone 2 by water through the gap, and during the process of the excess water flowing to the back of the curb stone 2, the excess water is divided into two parts and enters the drainage channel 23 on the curb stone 2, and then the drainage channel 23 is inclined to the drainage position of the sewer grid, so that the divided rainwater is concentrated and discharged to the sewer, reducing the problem of excessive erosion of the soil on the back of the curb stone 2 by water, and the water seeps into the assembly opening 22 from the side of the abutment 3, so that the water flows to the ground through the drainage surface 221, and during the flowing process, it can provide enough absorption area for the ground, reducing the problem of soil loss caused by rainwater flowing to a certain position on the ground.

[0043] The above only describes some exemplary embodiments of the utility model in a descriptive manner, without doubt, for ordinary skilled persons in the art, the described embodiments can be modified in various ways without deviating from the spirit and scope of the utility model. Therefore, the above drawings and description are illustrative in nature and should not be understood as limiting the scope of protection of the utility model claims.
