Abstract
The utility model discloses a pervious sidewalk structure which comprises a kerb and a sidewalk on the outer side of the kerb, wherein the sidewalk comprises a pervious surface layer, a pervious leveling layer, a pervious base layer, a reversed filter pad layer and a roadbed from the top down; the inner end part of the roadbed is sunken and forms a groove with the outer side face of the kerb; the groove is filled with the lower part of the inner end part of the reversed filter pad layer; waterproof geotextile is laid between the reversed filter pad layer and the roadbed and between the reversed filter pad layer and the kerb; a horizontal pervious pipe is laid at the lower part of the inner end part of the reversed filter pad layer in the length direction of the sidewalk; and the pervious pipe is close to the bottom of the groove and is communicated with a municipal drainage system. The structure can drain redundant rainwater permeated onto the roadbed through the pervious pipe, the durability requirement of the sidewalk structure is ensured, the rainwater can be permeated below the sidewalk, and the structure is good in waterproof and drainage effect, prevents the rainwater from being permeated into the roadway, and effectively protects the surface of a roadway.
Description
Technical field
The utility model relates to a kind of road structure, is specifically related to a kind of permeable structure of sidewalk.
Background technology
Along with the quickening of expanding economy and urban construction paces, the earth's surface of modern city is covered by material water-proof material gradually, forms " artificial desert " on ecology.Water permeable sidewalk can improve the utilization rate of rainfall resource, improve the comfortableness of rainy day walking, the adjusting ambient temperature, meet the construction safe environment protection type of country's proposition, the requirement of conservation-minded society, traditional water permeable sidewalk, although permeable effect is relatively good, but unnecessary rainwater can infiltrate through road surface the roadbed of lower floor, affect stability and the durability of roadbed, water also may, through the supercrust in sidewalk roadbed and infiltration track, road kerb lower end, cause damage to carriageway surfacing simultaneously.
The shortcoming of prior art is: existing water permeable sidewalk structure drainage weak effect, unnecessary water can infiltrate the roadbed of lower floor through road surface, affect stability and the durability of roadbed.
The utility model content
The purpose of this utility model is to provide a kind of waterproof and the good permeable structure of sidewalk of drainage effect.
For achieving the above object, the technical solution of the utility model is as follows: a kind of permeable structure of sidewalk, the sidewalk that comprises road kerb and the outside thereof, this sidewalk comprises the water permeability surface layer arranged from top to bottom, the water permeability levelling course, water permeability basic unit, anti-filter bed course and roadbed, the inner end of described roadbed is recessed, and form groove with the road kerb lateral surface, described groove is filled up in the bottom of described anti-filter bed course inner end, be equipped with the waterproof geotextiles between described anti-filter bed course and roadbed and road kerb, bottom at described anti-filter bed course inner end is equipped with horizontal water-permeable pipe along the sidewalk length direction, this water-permeable pipe is near described bottom portion of groove, and be communicated with municipal drainage system.
Adopt said structure, road kerb is between roadway and sidewalk, it is high inboard low that sidewalk is generally the outside, road kerb is positioned at the inboard, sidewalk, rainwater flows from lateral, sidewalk road kerb, through the water permeability surface layer, the water permeability levelling course, water permeability basic unit, the anti-filter bed course flows down, a small amount of water can infiltrate roadbed, enter municipal drainage system through water-permeable pipe in the groove of unnecessary current direction lower, avoid excessive rainfall to cause damage to roadbed, the waterproof geotextiles can make unnecessary water concentrate in groove to discharge through water-permeable pipe, can prevent that unnecessary water from immersing roadway from the junction of road kerb and roadbed simultaneously, effective protection roadway road surface, guaranteed structure of sidewalk durability demand, can make again rainwater thoroughly to sidewalk, waterproof and drainage effect are good.
Described waterproof geotextiles outer end to the distance of groove is more than or equal to 200mm.
Can effectively stop unnecessary water to infiltrate roadbed, unnecessary water is flowed in the groove of lower.
The thickness of described water permeability levelling course is greater than the thickness of water permeability surface layer, and the thickness of described water permeability base is greater than the thickness of described water permeability levelling course.
Described water permeability surface layer is the water-permeable cement concrete layer, and described water permeability levelling course is the medium coarse sand bed course, and water permeability basic unit of described water permeability basic unit is the permeable cement stabilized zone.
The intensity that water-permeable cement concrete layer guarantor trade is attractive in appearance and enough, the medium coarse sand bed course is more smooth by sidewalk, the permeable better effects if of permeable cement stabilized zone, the anti-filter bed course makes water flow better.
The width of described roadbed is greater than the distance of waterproof geotextiles outer end to the road kerb lateral surface.
The too wide meeting of waterproof geotextiles makes rainwater all concentrate on the roadbed top, and can not a small amount of the flowing down from roadbed.
The beneficial effects of the utility model are: the unnecessary rainwater infiltrated on roadbed can be discharged through water-permeable pipe; guaranteed structure of sidewalk durability demand, can make again rainwater thoroughly to sidewalk, waterproof and drainage effect are good; avoid rainwater to infiltrate roadway simultaneously, effectively protect the roadway road surface.
The accompanying drawing explanation
Fig. 1 structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, a kind of permeable structure of sidewalk, the sidewalk that comprises road kerb 6 and the outside thereof, road kerb 6 is between roadway and sidewalk, this sidewalk comprises the water permeability surface layer 1 arranged from top to bottom, water permeability levelling course 2, water permeability basic unit 3, anti-filter bed course 4 and roadbed 5, the inner end of roadbed 5 is recessed, and form groove with road kerb 6 lateral surfaces, described groove is filled up in the bottom of anti-filter bed course 4 inner ends, be equipped with waterproof geotextiles 7 between anti-filter bed course 4 and roadbed 5 and road kerb 6, waterproof geotextiles 7 outer ends to the distance of groove is more than or equal to 200mm, bottom at anti-filter bed course 4 inner ends is equipped with horizontal water-permeable pipe 8 along the sidewalk length direction, this water-permeable pipe 8 is horizontally disposed with along the sidewalk length direction, and near bottom portion of groove, and be communicated with municipal drainage system.
Water permeability surface layer 1 is the water-permeable cement concrete layer, water permeability levelling course 2 is the medium coarse sand bed course, water permeability basic unit of water permeability basic unit 3 is the permeable cement stabilized zone, and the thickness of water permeability levelling course 2 is greater than the thickness of water permeability surface layer 1, the thickness of water permeability basic unit 3 is greater than the thickness of water permeability levelling course 2, and the width of roadbed 5 is greater than the distance of waterproof geotextiles 7 outer ends to road kerb 6 lateral surfaces.
