Abstract
The utility model discloses a kind of permeable road structures of lightweight, and including base course, road surface structare layer and supercrust successively from bottom to top, the base course is light foam concrete roadbed.The utility model has the characteristics that permeable effect is good, drainage efficiency is high, mechanical strength is kept, environmental-friendly, can be widely applied to road administration construction field.
Description
Technical field
The utility model relates to road administration construction fields, more particularly to a kind of permeable road structure of lightweight.
Background technique
With the continuous dilatation of China's urban construction, existing pumping equipment has not adapted to the development in city.Every rain
Season, quite a few city of China, even part influential city in the world will form the flood of large area, shape
At the peculiar scene of ground 21 century, underground fifties in last century, bring inconvenience to the normal production and living of the people.This needs big
The municipal administration transformation of scale, but be all inextirpable in a short time no matter from fund or on the time.To prevent and coping with city
The deficiency of Disaster Defense Capability and mechanical drainability, many cities propose the concept in " sponge city ", try hard to making full use of now
On the basis of having pumping equipment, by the adjustment of part, the effect of making existing pumping equipment, reaches maximum, reduces or avoids as far as possible
It is influenced caused by living because of Waterlogging to the people.
Utility model content
The purpose of this utility model is to overcome the deficiencies of above-mentioned background technique, provide a kind of permeable road knot of lightweight
Structure makes it have the feature that permeable effect is good, drainage efficiency is high, mechanical strength is kept, environmental-friendly.
The permeable road structure of a kind of lightweight provided by the utility model, including base course, road surface knot successively from bottom to top
Structure layer and supercrust, the base course are light foam concrete roadbed.
In the above-mentioned technical solutions, the road surface structare layer is cement stabilized macadam permeable pavement structure layer.
In the above-mentioned technical solutions, light foam concrete roadbed bottom is additionally provided with the rubble being connected with foundation soil
Permeable stratosphere, the permeable stratosphere two sides of the bottom of rubble are respectively equipped with weeper drain.
The permeable road structure of the utility model lightweight, specific effect are mainly manifested in following several respects:
One, good water permeability, can be broken quickly through the water permeability of itself and with cement before precipitation is largely assembled
The cooperation of stone permeable pavement structure layer, rubble permeable stratosphere and weeper drain, while accumulating a part of rainwater, moreover it is possible to fast
Rainwater is discharged into underground irrigation canals and ditches by speed, prevents accumulated water and waterlogging disaster.
Two, durability and stability are good, light foam concrete category cement class material, service life and cement concrete phase
Together, have fabulous durability, and after tested it is found that when light foam concrete from road surface top surface be greater than 25cm when, automobile
Additional stress caused by dynamic load (ground connection pressure is 0.70MPa) is no more than 1/5 (0.14MPa) of total stress, if light foam
Concrete strength takes fatigue strength mean value 0.88MPa, stress ratio Y=0.16, then light foam concrete it is permeable/water storage roadbed
N ≈ 10 can be used29It is secondary.Obviously, light foam concrete roadbed can resist automobile dynamic load enough, while can ensure and use year
Limit.
Three, bulk density and intensity controllability can control lightweight by adjusting the containing ratio of stomata in light foam concrete
The full bulk density of foam concrete roadbed is in 4~12kN/m3Between, control intensity adjusts (intensity in engineering within the scope of 0.3~5Mpa
Main application range is 0.3~1.5Mpa).
Four, good environmental protection, light foam concrete is to the pollution-free effect of the natural environments such as soil, water, air, simultaneously
It is applied to can avoid the destruction to environment such as high raising digging in infilling work construction, to conservation of nature Eco-environmental Significance weight
Greatly, environment-friendly advantage is obvious.
Detailed description of the invention
Fig. 1 is the schematic diagram of the permeable road structure of the utility model lightweight.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and embodiments, but the embodiment should not be understood
For limitations of the present invention.
Referring to Fig. 1, the permeable road structure of the utility model lightweight, including base course, pavement structure successively from bottom to top
Layer and supercrust 1, the base course are light foam concrete roadbed 2.
The road surface structare layer is cement stabilized macadam permeable pavement structure layer 3.
2 bottom of light foam concrete roadbed is additionally provided with the permeable stratosphere 4 of the rubble being connected with foundation soil, described
Permeable 4 two sides of the bottom of stratosphere of rubble are respectively equipped with weeper drain 5.
The cement stabilized macadam permeable pavement structure layer 3 and the permeable stratosphere 4 of rubble can drain, and can also contain water, while institute
It states weeper drain 5 to be connected with existing city planting ductwork, can more easily drain precipitation, guarantee the passage energy of supercrust 1
Power.
Obviously, it is practical without departing from this can to carry out various modification and variations to the utility model by those skilled in the art
Novel spirit and scope.If in this way, these modifications and variations of the present invention belong to the utility model claims and
Within the scope of its equivalent technologies, then the utility model is also intended to include these modifications and variations.
The content being not described in detail in this specification belongs to the prior art well known to professional and technical personnel in the field.
