Referring to fig. 1-3, the present application provides a concrete pavement brick paving structure, comprising: the pavement bricks 1 are in a multi-row structure as shown in fig. 2, the pavement bricks 1 in two adjacent rows are not collinear, as shown in fig. 1, a plurality of spacing lugs 2 are arranged on the upper half part of the side surface of each pavement brick 1, each adjacent pavement brick 1 forms a gap through the spacing lugs 2, grouting openings 6 are formed among the pavement bricks 1, and preferably, one pavement brick 1 is hollow every 10-20 pavement bricks 1 to serve as the grouting openings 6, so that the construction progress is accelerated; the sand cushion layer 3 is arranged below the pavement bricks 1, and the sand cushion layer 3 has the main function of providing a plane for paving and uniformly supporting the pavement bricks so as to avoid the damage of the pavement bricks caused by stress concentration; grouting material (not shown) is poured into the pavement structure of the pavement bricks 1 through the grouting openings 6, and is used for penetrating into gaps between the sand cushion layers 3 and each pavement brick 1 and connecting the sand cushion layers 3 and each pavement brick 1 into a whole.

As shown in fig. 2, the pavement bricks 1 form a multi-row structure, the pavement bricks 1 of two adjacent rows are not collinear, namely, one pavement brick 1 in one row can be connected with two pavement bricks 1 of the other row, and the pavement bricks 1 are mutually meshed to form an interlocking structure, so that the overall stability of the pavement structure is greatly improved, the pavement bricks 1 of two adjacent rows are not collinear, and the stress generated by the vehicle load can be effectively dispersed by the segmented pavement structure; in addition, because the pavement bricks 1 of two adjacent rows are not collinear, and because each pavement brick 1 is arranged in a staggered way, the connection force between one pavement brick 1 and two pavement bricks 1 of the other row can be formed in the grouting material filling process, and the stability of the pavement bricks 1 is improved.

The spacing lugs 2 are arranged so that grouting material can flow in gaps of the pavement bricks 1 to connect the pavement bricks 1 into a whole; the spacing lugs 2 are arranged on the upper half part of the side surface of the pavement brick 1, so that grouting materials can enter the bottom of the pavement brick 1 from the grouting openings 6 and the sand cushion 3 can be filled upwards from the lower part of the pavement brick 1, and the filling is more full; on the other hand, as the spacing convex blocks 2 form gaps between the pavement bricks 1, the gaps have the functions of heat dissipation and water seepage, and can bear cold and hot abrupt changes without additionally arranging expansion joints.
