21 with basic unit 22 in use, prefabricated component buckle salient point (a1-1, a2-1, a3-1, b1-1, b2-1, b3-1) can be embedded in
In geotechnical grid, so as to enhance the globality of plate.
Due to being provided with buckle salient point (a1-2, a2-2, b1-2, b2-2) and snap-fit grooves in prefabricated component a, b side wall
(a2-3, a3-3, b2-3, b3-3) so that in Specific construction, any two pieces of horizontal precast concretes can produce closely
Lateral connection acts on, and so as to ensure the globality on road surface, prevents plate comes to nothing from starching phenomenon with purt.
After the completion of the first pre-cast concrete concrete bottom basic unit 21 and the second pre-cast concrete concrete base layer 22 are assembled,
Road top laying Anti-reflective Crack of Overlaying earth working material 4 and asphalt concrete pavement 5, so as to complete the assembling on road surface.
Because cement concrete 2 is improved to prefabricated by the utility model, and in the first pre-cast concrete concrete bottom basic unit
21 and second are provided with buckle structure on pre-cast concrete concrete 22, and the surrounding enviroment of construction site are not influenceed, moreover, working as
When the area of construction is larger, its construction cost is more lower slightly than traditional construction mode.
Certainly, the present embodiment is only a preferred embodiment of the present utility model, in other embodiments, prefabricated component a, b
Be also provided with three or more than three positive integer buckle salient point a1-2, a2-2, b1-2, b2-2 and three or three with
First-class positive integer snap-fit grooves a2-3, a3-3, b2-3, b3-3, it can still realize the using effect that the present embodiment is reached.
Preferred embodiment of the present utility model described in detail above.It should be appreciated that the ordinary skill people of this area
Member makes many modifications and variations without creative work can according to design of the present utility model.Therefore, all this technology necks
