Description

Technical Field

[0001] The present application relates to the technical field of road construction, and in particular to a fast-drainage sidewalk. Background Art

[0002] Road construction is an integral part of municipal engineering, and sidewalk construction is a crucial component. A sidewalk is typically a section of road separated by curbstones, guardrails, and other similar features for pedestrians. It's typically about four meters wide and located to the side of the roadway. It also includes paving tiles and blind paths.

[0003] At present, most of the floor tiles used in permeable sidewalks are permeable bricks, and the drainage effect is achieved through the porous structure of the permeable bricks. For example, the Chinese patent with authorization announcement number CN212670190U and publication date of March 9, 2021 discloses a permeable sidewalk, including multiple permeable bricks, a permeable mortar leveling layer, a permeable concrete layer, a gravel layer, a plain soil layer and a curbstone. An anti-seepage layer is arranged between the permeable concrete layer and the gravel layer; a plurality of recessed portions are opened on the permeable concrete layer, and the extension direction of each recessed portion is consistent with the width direction of the curbstone. A drainage pipe is laid in each recessed portion, and a plurality of water inlet holes are opened on the side wall of each drainage pipe. A drainage hole communicating with the drainage pipe is opened near the pipe mouth of each drainage pipe on the curbstone.

[0004] The above application provides a recessed portion on the permeable concrete layer and a drainage pipe in the recessed portion, and connects the pipe mouth of the drainage pipe to the drainage hole on the curb, so as to drain the accumulated water in the brick gap and ensure pedestrian use; however, the inventor believes that in heavy rain weather, there will be water accumulation on the vehicle road. When the drainage of the vehicle road surface is blocked, the accumulated water on the vehicle road may even overflow the curb and flood the sidewalk. The drainage hole on the curb is set lower, and the functions of the drainage pipe and the drainage hole cannot be realized. Therefore, it is necessary to design a fast-drainage sidewalk to ensure the normal use of the sidewalk; at the same time, the existing permeable bricks also have the defects of inconvenient installation and unstable connection with the mortar. Utility Model Content

[0005] The present application provides a fast-draining sidewalk that can drain water when it rains heavily or when water accumulates on the road and overflows the sidewalk, thereby ensuring the normal use of the sidewalk.

[0006] The rapid drainage sidewalk provided in this application adopts the following technical solution:

[0007] A fast-draining sidewalk, comprising a base layer, a cushion layer, a leveling layer and a brick surface layer arranged in sequence from bottom to top. Curb stones are provided on both sides of the base layer, the cushion layer, the leveling layer and the brick surface layer. Drainage layers are provided between both sides of the cushion layer, the leveling layer and the brick surface layer and the curb stones. The drainage layer is located above the base layer and the height of the drainage layer is lower than the height of the brick surface layer. A number of through holes are provided on the drainage layer.

[0008] Preferably, the drainage layer comprises a plurality of perforated bricks and the through hole directions of the perforated bricks are vertically arranged. The through holes of adjacent perforated bricks in the vertical direction are connected. The lower end of the drainage layer sinks into the base layer.

[0009] Preferably, the base layer is a soil layer, the cushion layer is a graded crushed stone layer, and the leveling layer is a concrete mortar layer.

[0010] Preferably, the brick surface layer comprises a plurality of permeable bricks laid horizontally. The permeable bricks are square structures. Convex parts are provided at the four corners of the lower end of the permeable bricks and the convex parts can sink into the leveling layer.

[0011] Preferably, a chamfer or a fillet is provided at the upper edge of the permeable brick, and a groove is formed between adjacent permeable bricks.

[0012] Preferably, the brick surface layer further comprises blind path bricks. The blind path bricks have different colors from the permeable bricks. A plurality of dot-shaped protrusions or straight strip-shaped protrusions are provided on the blind path bricks. The convex parts are provided at the bottom of the blind path bricks.

[0013] In summary, the present application includes at least one of the following beneficial technical effects:

[0014] 1. In the present application, curb stones are provided on both sides of the base layer, the cushion layer, the leveling layer and the brick surface layer. At the same time, drainage layers are provided between the cushion layer, the leveling layer, the brick surface layer and the curb stones. Since the height of the drainage layer is lower than the height of the brick surface layer and through holes are provided on the drainage layer, when the rainfall is large or the water accumulated on the vehicle road enters the sidewalk, the accumulated water can directly flow into the base layer through the drainage holes on the drainage layer, which can significantly improve the drainage efficiency compared with the traditional permeable bricks and ensure the use of the sidewalk.

[0015] 2. By setting the drainage layer as perforated bricks and the through holes of the perforated bricks are connected, it is convenient for construction while ensuring the drainage effect. At the same time, the drainage layer sinks into the base layer, which is convenient for the subsequent construction of the cushion layer and the leveling layer.

[0016] 3. By setting chamfers and rounded corners at the upper edge of the permeable bricks, grooves are formed between adjacent permeable bricks during construction, which helps improve the drainage efficiency. At the same time, blind path bricks are also provided for the blind to walk on. The permeable bricks and the blind path bricks have different colors, which is convenient for non-blind people to distinguish. At the same time, convex parts are provided at the bottom dead corners of the permeable bricks and the blind path bricks. During laying, the convex parts can be inserted into the leveling layer of the concrete mortar to improve the connection effect. At the same time, due to the convex parts at the bottom, it is also convenient to pick up during transportation and laying. Description of the Drawings

[0022] The following further describes the present application in detail with reference to the drawings.

[0023] The embodiment of the present application discloses a fast-draining sidewalk.

[0024] Refer to Figures 1 to 4 , a fast-draining sidewalk, including a base layer 1, a cushion layer 2, a leveling layer 3, and a brick surface layer 4 arranged in sequence from bottom to top. Curbstones 5 are arranged on both sides of the base layer 1, the cushion layer 2, the leveling layer 3, and the brick surface layer 4. The base layer 1 is a soil layer, the cushion layer 2 is a graded gravel layer, the leveling layer 3 is a concrete mortar layer, and a drainage layer 6 is arranged between the cushion layer 2, the leveling layer 3, and the brick surface layer 4 and the curbstone 5 on both sides. The drainage layer 6 is located above the base layer 1 and the height of the drainage layer 6 is lower than the height of the brick surface layer 4. A plurality of through holes are arranged on the drainage layer 6. Specifically, the drainage layer 6 includes a plurality of perforated bricks 601 and the through holes of the perforated bricks 601 are arranged vertically. The through holes of the adjacent perforated bricks 601 in the vertical direction are connected, and the lower end of the drainage layer 6 sinks into the base layer 1.

[0025] Refer to Figures 2 to 4The brick surface layer 4 includes a plurality of horizontally laid permeable bricks 401. The permeable bricks 401 are square in structure. The upper edge of the permeable bricks 401 is provided with chamfers or rounded corners. Grooves are formed between adjacent permeable bricks 401. The grooves can guide the water accumulated on the permeable bricks and improve the drainage efficiency. The brick surface layer 4 also includes blind paving bricks 402. The blind paving bricks 402 are different in color from the permeable bricks 401. There are multiple dot-shaped protrusions or straight strip-shaped protrusions on the blind paving bricks 402. The four corners of the lower ends of the blind paving bricks 402 and the permeable bricks 401 are provided with protrusions 7, and the protrusions 7 can sink into the leveling layer 3. During construction, first, according to the excavation position, Insert the curbstone 5 vertically into the base layer 1, then lay multiple layers of porous bricks in contact with the curbstone 5, and construct the drainage layer 6. During the construction process, embed the porous bricks into the base layer 1, and then construct a cushion layer 2 of graded crushed stone and a leveling layer 3 of concrete mortar between the drainage layers 6 on both sides. Finally, lay the horizontal reinforcements of the permeable bricks 401 and the tactile bricks 402 evenly on the leveling layer 3. Since the four corners of the bottom of the permeable bricks 401 and the tactile bricks 402 are provided with protrusions 7, the protrusions 7 can be sunk into the leveling layer 3 during the laying process, ensuring the connection effect of the brick surface layer 4 and preventing the permeable bricks 401 or the tactile bricks 402 from warping.

[0026] When the present application is in use, when the rainfall is small, rainwater falls on the permeable bricks 401 of the brick surface layer 4, seeps into the ground through the porous structure of the permeable bricks 401, or is drained to the drainage layer 6 through the grooves on the brick surface layer 4, thereby achieving a drainage effect; and when the rainfall is large or the vehicle road drainage is blocked, and the accumulated water overflows the sidewalk, it can be drained through the drainage layer 6 on both sides of the brick surface layer 4, thereby achieving a fast drainage effect and ensuring the use effect of the sidewalk.

[0027] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
