The strength and stiffness of pitch pervious concrete pavement extend the service life on road surface.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of specific implementation mode of pitch pervious concrete pavement provided by the utility model.
Fig. 2 is the structural representation of pitch pervious concrete pavement another kind specific implementation mode provided by the utility model
Figure.
Fig. 3 is the structural representation of pitch pervious concrete pavement another kind specific implementation mode provided by the utility model
Figure.
Specific implementation mode
The following examples illustrate the utility model, but is not intended to limit the scope of the present invention.
As shown in figures 1 and 3, the utility model provides a kind of pitch pervious concrete pavement, which is characterized in that the drip
Green pervious concrete pavement includes pitch pervious concrete layer 1 and horizontally disposed in the pitch pervious concrete layer
At least two layers of TGXG 2 in 1.At least two layers of TGXG is arranged in the utility model in pitch pervious concrete pavement
(being, for example, 2-5 layers), can prevent reflection crack, the TGXG on upper layer from can increase road surface positioned at the TGXG of bottom
Intensity reduces track, and to increase the strength and stiffness of pitch pervious concrete pavement on the whole, extend road surface uses the longevity
Life.
The distance of a kind of specific implementation mode, adjacent TGXG 2 is 1-10 centimetres, 2 distance of TGXG of top layer
The distance at 1 top of pitch pervious concrete layer is 1-5 centimetres, and undermost TGXG 2 is apart from 1 bottom of pitch pervious concrete layer
The distance in portion is 1-5 centimetres.Those skilled in the art can also be configured TGXG, this practicality according to practice of construction situation
It is novel to repeat no more.
TGXG (geogrid) is a kind of main geosynthetics, and compared with other geosynthetics, it has
There are unique performance and effect, is commonly used for the muscle material of earth structure or the muscle material of composite material etc., such as the TGXG 2
It can be formed by crisscross plastic bar hot pressing, the network interface size of TGXG 2 can be (1-20 centimetres) × (1-20 lis
Rice), thickness can be 4 millimeters -2 centimetres, and the material of plastic bar can be the high molecular polymers such as polypropylene, polyvinyl chloride.
In order to improve the horizontal direction shearing force between TGXG and pitch pervious concrete layer, prevent TGXG from sliding
It is de- and it is whole fall off, as shown in Figure 1, the plastic bar staggered place can be provided with upward the first protrusion 3 and downward second
