Description

Pavement paving structure with high water permeability

Technical Field

The utility model relates to a municipal road pavement technical field, concretely relates to pavement structure of mating formation with high water permeability.

Background

The conventional permeable sidewalk consists of kerbstones, permeable brick surface layers, leveling layers, permeable concrete, graded broken stones and soil foundations. When raining, rainwater permeates into the ground through the surface layer and the structural layer of the sidewalk, so that the pedestrian pavement is free of accumulated rain and the walking comfort of pedestrians is guaranteed.

When the rainfall is larger in the southern city, the water permeability coefficient of the soil foundation is far smaller than that of each structural layer of the sidewalk, so that the rainwater cannot be timely removed from each structural layer and the soil foundation of the sidewalk. The long-term surplus moisture can cause damage, subsidence and other diseases of the pavement.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model provides a pavement structure of mating formation with high water permeability to solve current pavement rainwater and can not in time discharge's technical problem.

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

the utility model provides a pavement structure with high water permeability which the key lies in: including the soil base course, the soil base course upper berth is equipped with receives the water film, receives the water film and from supreme laying in proper order down and be equipped with graded broken stone bed course, the concrete base course that permeates water and the surface course that permeates water, it has the blind ditch along road length direction shaping to distribute on the soil base course, receive the water film part and cover on the inner wall of blind ditch, the part covers on the soil base course, the curb part that sets up along road length direction is laid to the tip of graded broken stone bed course, the concrete base course that permeates water and the surface course that permeates water, it has the hole of transversely permeating water to distribute on the curb part.

By adopting the structure, the water collecting film can collect rainwater permeating from the road surface into the blind ditch and drain away in time, so that the rainwater is prevented from permeating into the soil base layer in a large amount and depositing in the soil base layer, the integral structural support of the soil base layer on the sidewalk is fully ensured, and the diseases such as damage and subsidence of the pavement surface of a pedestrian can be avoided. Meanwhile, when the permeable surface layer, the permeable concrete base layer and the graded broken stone cushion layer cannot timely permeate a large amount of rainwater downwards, the rainwater can flow to the transverse permeable holes in the curb part, and the pedestrian road is prevented from being damaged due to accumulated water.

Preferably, the method comprises the following steps: the section of the blind ditch is in an inverted trapezoid shape. By adopting the structure, the construction is facilitated.

Preferably, the method comprises the following steps: the blind ditch is filled with gravel. By adopting the structure, the supporting strength of the sidewalk can be improved on the basis of ensuring the drainage performance.

Preferably, the method comprises the following steps: the permeable surface layer is formed by laying permeable bricks. Adopt above-mentioned structure, can in time absorb water to the concrete base course that permeates water with the help of the clearance that the surface course has.

Compared with the prior art, the beneficial effects of the utility model are that:

adopt the utility model provides a pavement structure of mating formation with high water permeability, the rainwater can be through the timely row of the transverse hole of permeating water on french drain and the curb part on the soil basal layer and walk, has avoided a large amount of infiltration of rainwater and deposit in the soil basal layer, has fully guaranteed the soil basal layer to the holistic structural support nature of pavement, can stop diseases such as pavement damage, subsidence.

Detailed Description

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

As shown in fig. 1, a pavement paving structure with high water permeability is sequentially provided with a permeable surface layer 5, a permeable concrete base layer 4, a graded broken stone cushion layer 3, a water collecting film 2 and a soil base layer 1 from top to bottom, wherein the permeable surface layer 5 is made of permeable bricks or permeable concrete and the like, the soil base layer 1 is preferably a natural foundation, blind ditches 6 formed along the length direction of the pavement are distributed on the soil base layer 1, the water collecting film 2 partially covers the inner walls of the blind ditches 6 and partially covers the soil base layer 1, and when water is accumulated on a rainy day or a pavement, the water collecting film 2 can collect water permeated from the pavement into the blind ditches 6 and drain away in time, so that rainwater can be prevented from permeating into the soil base layer 1 in a large amount and depositing in the soil base layer 1, the structural support of the soil base layer 1 on the whole pavement is fully ensured, and diseases such as damage and sinking of the pavement surface can be avoided.

The blind ditch 6 may have an inverted trapezoid or rectangular cross section, and in this embodiment, the cross section is preferably configured as an inverted trapezoid to facilitate excavation. On the basis of ensuring the drainage performance of the blind ditch 6, in order to further improve the supporting strength of the sidewalk, gravel stones 9 can be filled in the blind ditch 6.

The curb part 7 that sets up along road length direction is laid to the tip of gradation rubble bed course 3, the concrete base course 4 that permeates water and the surface course 5 that permeates water, and it has horizontal hole 8 of permeating water to distribute on curb part 7, and when the surface course 5 that permeates water, the concrete base course 4 that permeates water and gradation rubble bed course 3 can not in time permeate a large amount of rainwater downwards, the rainwater also can be through horizontal hole 8 discharges of permeating water to help preventing that the pedestrian road is damaged because of ponding.

As shown in fig. 2, in order to facilitate the arrangement of the water permeable transverse holes 8, the kerb portion 7 is formed by arranging a plurality of stone strips 7a, and the water permeable transverse holes 8 are provided between two adjacent stone strips 7 a.

As shown in fig. 3, the transverse water permeable holes 8 may be formed directly in the respective stone strips 7a in addition to the above arrangement, and the respective stone strips 7a of the kerb portion 7 are sequentially abutted in a spliced state.

Finally, it should be noted that the above description is only a preferred embodiment of the present invention, and those skilled in the art can make various similar representations without departing from the spirit and the scope of the present invention.
