Description

Permeable pavement for sidewalk

Technical Field

The application relates to the technical field of road construction, in particular to a permeable pavement for a sidewalk.

Background

At present, when public open places such as sidewalks and squares are built in cities, in order to solve the problems of surface water accumulation or unsmooth drainage in rainy days and the like, water permeable bricks are often directly paved on common concrete to serve as water permeable pavements of the open places.

The sidewalk refers to a part which is separated by kerbstones or guardrails and other similar facilities and is specially used for pedestrians to pass through, tree planting belts are generally arranged on two sides of the sidewalk, green plants are planted in the tree planting belts, a soil layer is laid on the sidewalk, and then a channel in the form of permeable bricks is laid on the sidewalk.

In view of the above-mentioned related art, the inventor believes that there is a defect that rainwater permeates into soil in a muddy soil layer after permeating through the water permeable bricks, and when the rainwater is heavy, the drainage is not smooth, and rainwater accumulation may overflow the water permeable bricks.

SUMMERY OF THE UTILITY MODEL

In order to solve the not smooth defect of drainage under the brick that permeates water, this application provides a pavement permeable pavement.

The application provides a pavement permeable pavement adopts following technical scheme:

the utility model provides a pavement permeable pavement, includes curb, planting area and pavement, the pavement includes soil matrix layer and lays in brick that permeates water on the soil matrix layer, the soil matrix layer orientation the water conservancy diversion way has been seted up on the surface of brick that permeates water, the water conservancy diversion way is followed the length direction of pavement extends and sets up, the water conservancy diversion way intussuseption is filled with the metalling.

Through adopting above-mentioned technical scheme, through seting up the water conservancy diversion way at the soil matrix layer, make on the one hand can save more rainwater under the brick that permeates water, on the other hand water conservancy diversion way can lead away the rainwater, reduces the accumulation of rainwater, and the rubble layer of packing plays the supporting role to the brick that permeates water, has a large amount of gaps between the rubble of rubble layer simultaneously, and the rainwater can flow at rubble layer power, reduces the influence to the rainwater flow.

Preferably, water guide surfaces are arranged on two sides of the water guide channel, the water guide surfaces are arranged in a downward inclined mode in the direction close to the water guide channel, and a gravel layer is also arranged between the water guide surfaces and the water permeable bricks.

Through adopting above-mentioned technical scheme, the gravel layer between water guide face and the brick that permeates water plays the supporting role to the brick that permeates water, and also has a large amount of spaces between the gravel layer between water guide face and the brick that permeates water, can save more ponding, and the water guide face plays the guide effect, assembles the guiding way to the rainwater of permeating in the brick that permeates water, finally sends away the rainwater through the guiding way.

Preferably, a soil layer is arranged between the gravel layer and the water permeable bricks.

Through adopting above-mentioned technical scheme, because the metalling height is uneven, set up the soil horizon for the brick that permeates water obtains better support, makes the pavement level and smooth more, and the soil horizon is less to the infiltration influence of rainwater simultaneously, and the rainwater still can infiltrate in the metalling.

Preferably, the soil base layer is provided with a plurality of drainage channels, the drainage channels are respectively arranged on two sides of the diversion channel, the drainage channels are arranged at intervals along the length direction of the diversion channel, one end of each drainage channel is communicated with the diversion channel, and the other end of each drainage channel extends into the planting zone.

Through adopting above-mentioned technical scheme, set up the water dredging channel and take the intercommunication with planting the water conservancy diversion way for the rainwater of accumulating can flow into and plant the area, because plant green planting in planting the area, make the infiltration rate of planting rainwater in the area higher, thereby better lead away the ponding under the brick that permeates water.

Preferably, a first water guide pipe is embedded at the bottom of the flow guide channel, and a plurality of water permeable holes are formed in the first water guide pipe.

Through adopting above-mentioned technical scheme, bury the first aqueduct underground to set up the hole of permeating water on first aqueduct, make ponding can flow in the rubble layer better through first aqueduct.

Preferably, a second water guide pipe is embedded in the drainage channel, a plurality of water permeable holes are also formed in the second water guide pipe, and the second water guide pipe is communicated with the first water guide pipe.

Through adopting above-mentioned technical scheme, set up the second aqueduct, support the water dredging channel on the one hand, on the other hand, better the leading-in planting area of rainwater.

Preferably, the diameter of the water permeable holes is 2mm-4 mm.

Through adopting above-mentioned technical scheme, the diameter setting in the hole of permeating water is in less within range, reduces the possibility that soil falls into in first aqueduct and the second aqueduct on the one hand, and on the other hand keeps rainwater freely to flow in and flow out first aqueduct and second aqueduct, and the rainwater is better oozes in soil basic unit and the planting area.

Preferably, drainage blind pipes are arranged in the first water guide pipe and the second water guide pipe.

Through adopting above-mentioned technical scheme, set up the drainage blind pipe, improve the ability that flows of rainwater in first aqueduct and second aqueduct, and first aqueduct and second aqueduct play the guard action to the drainage blind pipe.

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

1. the diversion channel is arranged on the soil foundation layer, so that more rainwater can be stored under the water permeable bricks on one hand, the diversion channel can guide away the rainwater on the other hand, the storage of the rainwater is reduced, the filled gravel layer plays a supporting role on the water permeable bricks, meanwhile, a large number of gaps are formed among gravels of the gravel layer, the rainwater can flow in the gravel layer, and the influence on the flowing of the rainwater is reduced;

2. the gravel layer between the water guide surface and the water permeable bricks plays a supporting role for the water permeable bricks, a large number of gaps are formed between the gravel layers between the water guide surface and the water permeable bricks, more accumulated water can be accumulated, the water guide surface plays a guiding role, rainwater permeating in the water permeable bricks is gathered into the flow guide channel, and finally the rainwater is conveyed away through the flow guide channel;

3. set up the water dredging channel and communicate flow guide and planting area for the rainwater of gathering can flow into and plant the area, because plant green planting in the planting area, make the infiltration rate of rainwater higher in the planting area, thereby better lead away the ponding under the brick that permeates water.
