Description
Technical field
The present invention relates to a kind of pavement structures, and in particular to one kind belonging to road work from the permeable whole road surface of catchmenting of snow melt
Journey technical field.
Background technology
Common porous pavement can not ensure the safety of road travel under conditions of northern snowfall freezes, and need to use machinery
Deicing salt, the mode of mechanical shoveling snow eliminate ice and snow on road surfaces, and this mode is easy road pavement and damages.It applies at present in asphalt road
The deicing salt in face, road pavement has certain corrosiveness, and has certain destruction, high expensive to ecological environment around.
Current snow melting material, is mainly made of salt, and salt, which is precipitated, to be accumulated with rainwater infiltration in ground, is easy to draw
Play soil property salinization；Effectively ground superficial water cannot be discharged for traditional permeable pavement road surface, and the ground impregnated often collapses
It is heavy to sag, and causes the destruction of road table and brings security risk, and is low to the utilization rate of rainwater so that great lot of water resources wastes, Bu Nengman
The demand in sufficient nation-building sponge city.Common porous pavement can not ensure road travel under conditions of northern snowfall freezes
Safety, traffic obstacle occurs and is difficult to avoid that often.
Invention content
It is an object of the invention to overcome the deficiencies of existing technologies, Summer Heavy Rainfall flood, winter can be alleviated by providing one kind
Icy on road, effective recycling rainwater from the permeable whole road surface of catchmenting of snow melt.
In order to reach above-mentioned technique effect, the present invention provides one kind from the permeable whole road surface of catchmenting of snow melt, the road surface

Further, the captation is aqueduct.
Further, the inside of the aqueduct is V-shaped structure, and T-type diversion trench, aqueduct lower half are provided in pipe
It is provided with infiltration duct, first half sealed set, aqueduct discharge ends are provided with glass pumice, for absorbing and filter water quality, rain
Water enters aqueduct by infiltration lane and flows to discharge ends.
Further, 20~60mm of the graded broken stone layer medium stone grain size.
Further, the low freezing point protective agent coating is that protective agent and low freezing point material are mixed to get, the low ice
The quality for selecting material is the 2%~10% of the protective agent quality.
Further, the low freezing point colorful surface layer and the low freezing point original color surface layer are in concrete and low freezing point material
Mixture, the quality of the low freezing point material is the 2%~10% of the concrete quality.
Further, protectant ingredient be acrylic resin 63~73%, film forming agent 3~5%, flocculation aid 2~
3%, polyurethane 14~17%, propylene glycol 1~2%, pigment 8~10%, polyurethane curing agent 1.5~2%, antifoaming agent 0.5~
1%, remaining is water.
Protective agent in the present invention has the function of enhancing durability and aesthetics, and smearing protective agent rear surface is smooth, mouth
The rubbish that fragrant sugar etc. easily adheres to can be washed away with water, and tamper meets water self-cleaning, prevent usage time is long from making permeable whole road
Face gap gets dirty and blocks hole, hinders the effect of its melting ice and snow.
Road surface operation principle provided by the invention is：The density of low freezing point material is less than the density of water, and low freezing point is color
Color surface layer and bottom have many tiny holes, low freezing point material by inside low freezing point colorful surface layer, low freezing point primary colors bottom and
The hole on surface is slowly precipitated, and the hole through mixture is gradually migrated to road table, interacts with ice and snow, reduces the condensation of water
Point causes the reduction of road snow icing freezing point, ice and snow to be converted into liquid water or vapor discharge road surface, play melting ice and snow and subtract
The slow effect freezed.For the smaller situation of snowfall, low freezing point road surface can directly melt road table accumulated snow；It is larger for snowfall
Situation, the snow deposit directly contacted with road surface are melted, and water will not be in the secondary icing of road table, therefore avenges and easily removed from road table,
Cooperation is artificial and machinery clears the snow, and greatly improves the efficiency that clears the snow,.Snow-broth after thawing by being seeped into base under pervious concrete, with
Aqueduct passes through double purification, then the accumulation water such as be discharged into concave herbaceous field facility.
The present invention has the advantages that：The present invention is using environmentally friendly low freezing point material and concrete and protective agent material
Material mixed, and combine aqueduct, after north of china in winter snowfall, face layer accumulated snow can fast melt, no longer freeze, and face layer
Ice and snow is easy cleaning, does not damage road surface.North city Summer Heavy Rainfall flood can either be alleviated, reduce surface runoff；Winter Snow road
Face freezes, and is oozed under snow-broth is rapid after melting, the accumulated snow of road table constantly melts, and accelerates entire merging into nature, eliminates snowfall icing band
The security risk come.Low freezing point material is combined with aqueduct, and snow-broth is oozed under effectively excluding, and protecting grassroots level reduces salinization substance and invades
Erosion, and can again be used in construction, green area irrigation, carwash, horse of drawing water with reclaiming clean rainwater, the rainwater of accumulation
The places such as bucket, fire-fighting, landscape water, realization efficiently use again.
Under the road surface of the application ensures in rain and snow, special road section and entire road have good service performance,
For solving China's ice and snow road Exploration on Train Operation Safety, urban waterlogging, reducing traffic accident rate and reducing Traffic Accident Loss, protect
Berm road periphery ecological environment has great economic benefit and social effect.
