Description

Water permeability pavement of urban road

Technical Field

The utility model relates to a pavement of urban road, especially a pavement with function of permeating water.

Background

With the development of urban construction, urban ground surfaces are increasingly covered by hardened pavements. The hardened pavement makes city appearance cleaner, but also causes rainwater to be difficult to infiltrate and lose supplement of underground water. Therefore, people invent the water permeable bricks, and pavements with water permeable functions on two sides of urban roads are paved by using the water permeable bricks, so that rainwater on the pavements can penetrate through the water permeable bricks and permeate into the ground.

An existing urban road paved with a water permeable sidewalk is shown in figure 1, sidewalks 3 are located on two sides of a main road 1 of the urban road, kerbs 2 are arranged on two sides of the main road 1, the kerbs 2 are higher than a road surface of the main road 1, the sidewalks 3 paved with water permeable bricks 4 are approximately flush with top surfaces of the kerbs 2, and a middle sand leveling layer 7 with the thickness of 30mm, a compacted broken stone base layer 8 with the thickness of 100mm, a middle sand cushion layer 9 with the thickness of 60mm and a compacted roadbed are sequentially arranged below the water permeable bricks 4 from top to bottom. When raining, rainwater falling on the surface of the sidewalk can penetrate through the water permeable bricks to seep downwards, but the seepage speed is limited, so that the conventional water permeable sidewalk still has the defect that the normal walking of pedestrians is influenced by accumulated water when the rainwater is heavy.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a can make the rainwater ooze down fast, reduce the water permeability pavement of the urban road of pavement surface ponding.

In order to achieve the above purpose, the utility model discloses technical scheme as follows:

the utility model provides a urban road's water permeability pavement, includes main road and the pavement that the main road both sides were spread by the brick that permeates water, the pavement with separate by the curb between the main road, the curb top surface is higher than main road surface, the pavement surface with the curb top surface flushes, the curb with the side that the brick that permeates water laminated mutually is provided with along the recess that curb length direction extends, and, be provided with a plurality of along its length direction interval on the recess and run through the hole of permeating water of curb thickness direction.

Further, the cross section of the groove is arc-shaped.

Furthermore, the width of the opening of the cross section of the groove is 20-40mm.

Furthermore, the diameter of the water permeable holes is 10-30mm.

Further, the groove is aligned with the water permeable brick in the thickness direction of the water permeable brick.

Further, the height difference between the top surface of the kerbstone and the main road surface is more than or equal to 50mm.

Furthermore, a medium sand leveling layer, a compacted gravel base layer, a medium sand cushion layer and a compacted roadbed are sequentially arranged below the water permeable bricks from top to bottom.

Further, the thickness of the medium sand leveling layer is 30mm, the thickness of the compacted gravel base layer is 100mm, and the thickness of the medium sand cushion layer is 60mm.

The utility model discloses a set up on the curb with the recess that the brick layer that permeates water of pavement meets and run through the hole of permeating water of main road one side for the rainwater on pavement surface can also transversely arrange main road one side via the hole of permeating water on the curb when passing the brick that permeates water and ooze down, therefore has accelerateed the row away of pavement surface rainwater, has reduced the accumulation of rainwater on pavement surface, has made things convenient for the walking of people on the pavement.

Detailed Description

The present invention will be further described with reference to the following examples.

Fig. 2 and 3 show an example of a water permeable sidewalk of an urban road according to the present invention.

As shown in the figure, the water permeable sidewalk for the urban road in this example includes a main road 1 and a sidewalk 3 (the left sidewalk 3 is not shown) paved with water permeable bricks 4 on both sides of the main road 1, the sidewalk 3 and the main road 1 are separated by kerbs 2, the top surface of the kerbs 2 is higher than the road surface of the main road 1, the surface of the sidewalk 3 is flush with the top surface of the kerbs 2, the side surface of the kerbs 2, which is attached to the water permeable bricks 4, is provided with grooves 5 extending along the length direction of the

kerbs

2, and 5 water permeable holes 6 penetrating through the thickness direction of the kerbs 2 are arranged on the grooves 5 at intervals along the length direction.

The section of the groove 5 is arc-shaped, the opening width of the section is 30mm, and the diameter of the water permeable hole 6 is 15mm. The groove 5 is aligned with the water permeable bricks 4 in the height direction.

The height difference between the top surface of the kerb 2 and the road surface of the main road 1 is 150mm.

A medium sand leveling layer 7 with the thickness of 30mm, a compacted gravel base layer 8 with the thickness of 100mm and a medium sand cushion layer 9 with the thickness of 60mm are sequentially arranged below the water permeable bricks 4 from top to bottom, and a roadbed (not shown in the figure) is arranged below the cushion layer 9.

Instead of a circular arc, the groove 5 may also have any other suitable cross-sectional shape, which facilitates the machining of the kerbstone 2.

As the auxiliary drainage structure of the sidewalk 3, the size of the cross-section opening of the groove 5 should be smaller than the thickness of the water permeable brick 4, and the thickness of the existing water permeable brick 4 is mostly 50mm, so the size of the cross-section opening of the groove 5 can be selected within the range of 20-40.

In order to avoid the sand loss of the leveling layer 7 below the water permeable bricks 4, the lower edges of the section openings of the grooves 5 are not lower than the lower surfaces of the water permeable bricks 4.

As the water discharge port, the diameter of the water permeable holes 6 of the groove 5 can be selected within the range of 10-30mm, and the number of the water permeable holes 6 of the groove 5 can be selected by considering the length of the groove 5, the size of the cross-sectional opening of the groove 5, and the diameter of the water permeable holes 6.

In order to drain water smoothly, the length direction of the permeable bricks 4 should be laid perpendicular to the length direction of the kerb 2.

In addition, the curb 2 in the example is only one of many existing curbs, and the heights of the top surface of the curb 2 and the road surface of the main road 1 are different according to the types of the curbs 2, not all 150mm in the example.

Finally, it should be pointed out that, in addition to the above examples, the technical solution protected by the present invention may also have various other embodiments that can be made by those skilled in the art, and the above examples are only used for illustration and do not limit the scope of the present invention.
