Description
Technical field
The application belongs to urban pavement technical field of structures, and in particular to a kind of high intensity, the porous pavement of high osmosis
Structure.
Background technology
Current urban pavement is all substantially stop water layer, and accounts for the city gross area of significant proportion.Easily traffic base
Although Infrastructure, smooth road give people trip and bring great convenience, but these non-porous pavements are to the ecological ring in city
Border also brings greatly negative effect.
First, the impermeability of paving by valuable natural precipitation completely with lower soil and underground water blocking, drop
Water major part is entered in the earth surface water sources such as rivers,lakes and seas by sewerage system pipe network, and the excess of urban groundwater is taken out in addition
Take, cause Urban Underground water level more and more lower, form " funnel type " level of ground water geologically, trigger ground to decline, edge
Haiti area also results in inwelling.Precipitation is usually that the drainage grade or ground for first passing through ground show that ditch enters sewer,
Need that by the rainwash of relatively long distance Urban Underground drainage system could be entered before into sewer, around here in the feelings of heavy showers
Larger flow path surface will be produced under condition, the burden of Cheng Yi cities drainage pipeline networks is increased, or even causes urban type rain flood
Occur.Rainwash process makes the rainwater of initial relative clean dissolve in substantial amounts of urban surface pollutant, in this runoff process
The secondary pollution of generation, peripheral ground natural water is entered by sewerage system, has aggravated the pollution level of natural water.
Secondly, the ground pavement of this surface compact is unfavorable for alleviating the noise pollution in city, is mainly produced from road traffic
Noise；The rainy day due to hardened ground can not draining in time, cause surface gathered water, " drift is sliding, splash, night the rainy day is driven a vehicle and is produced
Between dazzle " etc. phenomenon, to pedestrian trip and vehicle traveling make troubles and potential safety hazard.Furthermore, it is this it is fluid-tight mat formation with
Collective effect is built in surrounding cities, can increase city " tropical island effect ".Also because its color is gloomy, lack angry, it is existing
The city in generation is also referred to as " heat island of grey ".
Porous pavement is completely different with compact-type pavement structure before.Porous pavement is using the stronger infiltration of celluar concrete
Ability, stores in the hole of road surface structare layer by Rainfall Infiltration to soil matrix or by rainfall, forms groundwater reservoir.The permeable road of tradition
Face has the following disadvantages that one is limiting due to the celluar concrete by low intensity, can be only applied to parking lot, pavement,
The places such as meeting exhibition section pavement, the urban recreative square of exhibition, two are collected inside pavement structure because substantial amounts of precipitation is long-term
It is poly-, cause pavement structure immersion for a long time and damage.Accordingly, it would be desirable to one kind both can apply to each grade city row such as primary and secondary main line
Bus or train route face, while can be again the permeable pavement structure of the mankind's comfortable living environment of construction with natural environment coordinated growth.
