Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings.
As shown in fig. 1-5, a road surface structure is connected to locked groove formula of administering unstable subsidence of road, by the interconnect of a plurality of rectangle panel unit 1, panel unit 1 top surface is equipped with all around and connects through jam plate 10 between the adjacent panel unit 1 of slot 4, jam plate 10 comprises connecting plate 5 and two picture pegs 6, two picture pegs 6 are located connecting plate 5 below both sides respectively, two picture pegs 6 insert respectively adjacent panel unit 1 corresponding slot 4 in order to realize the connection to adjacent panel unit.
A set of adjacent limit lateral part of panel unit 1 is equipped with down boss 2, the bottom surface of lower boss 2 flushes with panel unit 1's bottom surface, the top surface of lower boss 2 is less than panel unit 1's top surface, another group of adjacent limit lateral part of panel unit 1 is equipped with and goes up boss 3 with lower boss 2 matched with, the top surface of going up boss 3 flushes with panel unit 1's top surface, the bottom surface of going up boss 3 is higher than panel unit 1's bottom surface, it is whole to form the road surface through last boss 3 and lower boss 2 mutual concatenation between the adjacent panel unit 1.
The gaps between adjacent panel units 1 are filled with asphalt cement 9.
The thickness of the connecting plate 5 is 8-12 mm.
The panel unit 1 is formed by pouring concrete. And a reinforcing steel bar mesh is arranged in the panel unit 1 and formed by criss-cross connection of transverse reinforcing steel bars 7 and longitudinal reinforcing steel bars 8.
The distance between the adjacent slots 4 on the panel unit 1 is 400-500 mm.
The side length of the panel unit 1 is 1.5-2 m. The thickness of the panel unit 1 is 140-300 mm.
The lock plate 10 is made of a steel plate.
The construction method comprises the following steps:
A. dismantling the original sunk pavement, and filling and tamping the foundation of the sunk part with loess;
B. splicing the panel units 1 with each other through the upper bosses 3 and the lower bosses 2 to form a whole pavement;
C. buckling and inserting the locking plates 10 into the corresponding slots 4 of the adjacent panel units 1, and connecting the adjacent panel units 1 through the locking plates 10;
D. the gap between adjacent panel units 1 is filled with asphalt cement 9.
The invention provides a prefabricated splicing type flexible pavement structure, wherein panel units 1 are connected in a matched mode through locking plates 10 and slots 4, and the panel units 1 can independently move up and down, so that the pavement has flexibility and certain deformation capacity.
