Description

A kind of road surface permeable pavement structure
Technical field
The utility model is related to urban pavement structures, and in particular to a kind of road surface permeable pavement structure.
Background technology
With the fast development of urbanization, with the wide of the large area of the impermeable materials such as stone material, cement, concrete construction The Municipals facility such as field, road, and covering of the vast waterproof pavement of these areas to original naturally permeable underlying surface, lead It causes the rainfall runoff that city underlying surface generates when rainfall to be difficult to down ooze, and is advanced by the time to form flood peak, be easy to cause city Ponding effectiveness factors.Road surface ratio shared in the waterproof underlying surface in urban area is higher, the rainfall runoff that surface generates Amount is also larger, and the ponding that road surface generates not only influences traffic, makes troubles to the trip of people, while also increasing urban waterlogging Risk.
Recently as the continuous propulsion of sponge urban construction, many areas start gradually by the impervious blanket of road with Permeable pavement is replaced, but has replaced two main problems of road generally existing of permeable pavement at present, when, due to before Road surface under the facilities such as inbuilt line equipment be all to be designed construction according to non-Soaking environment mostly, therefore, replace saturating Water is permeated or is stored in road lower structural layer and soil matrix through the rainwater oozed under mating formation after mating formation, to inbuilt below road Line equipment etc. affects, or even damage subsurface equipment;Second is that under being permeated by porous pavement after replacing permeable pavement The amount of rainfall come is more, is easy to impregnate the vulnerable area of soil matrix below damage road, and then cause harmful effect to road.
Utility model content
The utility model aim is to provide a kind of road surface permeable pavement structure.
Based on above-mentioned purpose, the utility model takes following technical scheme:
A kind of road surface permeable pavement structure, including the permeable pavement layer, screed-coat, base and the soil that set gradually from top to bottom Base is equipped with waterproof layer between the base and soil matrix, waterproof layer is obliquely installed, and is located at the base of that side of the tilting bottom of waterproof layer Layer is embedded with header, several flow concentration holes is laid on header, the side wall of the header is connected with drainpipe.
The flow concentration hole is distributed in the upper side wall of header;The outer wall of header is additionally provided with filter screen.
The filter screen is gauze, and gauze is wound on the outer wall of header.
The drainpipe has several, and several drainpipes are arranged along the length direction of header, and drainpipe is located at flow concentration hole Lower section.
Bed course is additionally provided between the waterproof layer and soil matrix, the bottom of base, the top of bed course are obliquely installed.
The angle of inclination of the waterproof layer is 3 ° -5 °;The waterproof layer is made of polyethylene waterproof coating, the thickness of waterproof layer Degree is 5cm.
Compared with prior art, the utility model has the advantages that:
The water assembled in base is collected and is drained, can largely reduced by the way that waterproof layer is arranged by the utility model Cross the amount of rainfall that road surface is penetrated into the soil matrix of road lower part, reduce in the soil matrix of road lower part inbuilt pipeline and its auxiliary device by The risk of water damage occurs for water logging and soil matrix, while being also beneficial to the Collection utilization of permeable pavement region rainfall runoff, can accelerate The infiltration rate of Reuter's water pavement surfaces rainfall runoff reduces surface pond risk.

Specific implementation mode
A kind of road surface permeable pavement structure, as shown in Figs. 1-3, including set gradually from top to bottom permeable pavement layer 1, look for Flat bed 2, base 3, bed course 5 and soil matrix 6 are equipped with waterproof layer 4 between the base 3 and bed course 5, waterproof layer 4 is obliquely installed, described The angle of inclination of waterproof layer 4 is 3 °(4 ° or 5 °), the waterproof layer 4 is made of polyethylene waterproof coating, and the thickness of waterproof layer 4 is 5cm, the bottom of the base 3, the top of bed course 5 are obliquely installed, and are located at the base 3 of that side of the tilting bottom of waterproof layer 4 It is embedded with header 8, several flow concentration holes 10 are laid on header 8, the flow concentration hole 10 is distributed in the upper side wall of header 8, The outer wall of header 8 is additionally provided with filter screen, and the filter screen is gauze, and gauze is wound on the outer wall of header 8, the collection The side wall of flow tube 8 is connected with drainpipe 9, and the drainpipe 9 has several, and several drainpipes 9 are set along the length direction of header 8 It sets, drainpipe 9 is located at the lower section of flow concentration hole 10.
Wherein:Permeable pavement layer 1 is the permeable face layer such as water-permeable brick, pervious asphalt or pervious concrete;Screed-coat 2:It is thoroughly Aqueous to be not less than permeable pavement layer, sand, coarse sand, dry cement mortar are constructed in general use, thickness 2-3cm;Base 3:Its Rigid base, semi-rigid type base, flexbile base three classes are generally included, permeable pellet, permeable may be selected according to regions resources difference The materials such as cement concrete, stabilization gravel are built, it is desirable that this layer has enough intensity, water penetration, water stability, continuous hole Rate is not less than 10%;Bed course 5:Bed course should be generally set when the earth base of road is cohesive soil, mainly use water penetration preferable The granular materials such as sand, gravel or harmless industrial residue are built, and particle accounting of the material particle size less than 0.075mm should not exceed 5%; Soil matrix 6:Natural soils layer below road.
When rainfall occurs, gradually converged in base 3 after being stopped by waterproof layer 4 by the rainwater oozed under the permeable pavement of road surface Collection, since the bottom of base 3 is there are certain gradient, under the rainwater that infilters in base 3 assemble and collected to its bottom of slope rapidly Flow tube 8 is collected, and municipal administration of the row to road periphery is guided by the drainpipe 9 being connect with header 8 into the rainwater in header 8 At Storm Sewer Network or low-lying permeable greenery patches.Accelerate the infiltration rate of road permeable pavement surface rain water runoff to a certain extent, Facilitate walk, while can also reduce down the burden for oozing rainwater in lower part soil matrix 6 of mating formation, reduces embedded underground of mating formation Underground municipal pipeline and its auxiliary device 7 risk that water damages occurs by water logging and soil matrix 6.
