Detailed Description
In order to make the technical solutions of the present invention better understood, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 to 4, the embodiment of the present invention provides a precast concrete block 1 for a rigid pavement of a road

The first member 11 of the precast concrete block 1 mainly functions to bear the load of the vehicle tire and transfer it to the second member 12, 12' therebelow. The first member 11 may be formed of reinforced concrete casting.
The second member 12(12 ') is formed by a plurality of vertical grids 120(120 ') and a plurality of horizontal grids 121(121 ') perpendicularly intersecting each other to form a grid structure, and a plurality of grid holes 122 are formed between the vertical grids 120(120 ') and the horizontal grids 121(121 '), wherein the grid holes 122 correspond to the plurality of water through holes 110 of the first member 11, and only the second member of the first structure is illustrated as a representative, and the second structure is the same as the first structure.
The vertical grating 120 is provided with a plurality of transverse water through holes 1201 communicated with the corresponding grating holes 122; and the horizontal grid 121 is provided with a plurality of longitudinal water through holes 1211 communicated with the corresponding grid holes 122.
Furthermore, the first structure 10 of the precast concrete block 1 and the second structures 12 and 12 'of the second structure 10' are formed with two supporting portions 13 and 13 'protruding downward at both ends in the longitudinal direction, respectively, and an arch structure formed between the two supporting portions 13 and 13'. The second member 12 of the first structure 10 of the precast concrete block 1 is provided with two first protruding step surfaces 14 corresponding to the lower parts of the two supporting parts 13; the second structural body 10 'of the precast concrete block 1 has a second member 12' having two convex second step surfaces 14 'formed at upper portions of the two supporting portions 13'.
The first step surface 14 and the second step surface 14' are complementary to each other so as to be snap-fitted together one at a time. In this way, the discontinuous loading of the base and the plate when the wheel passes through the joint of each adjacent unit in the traditional supporting structure can be avoided, thereby reducing the impact force and prolonging the service life of the joint. In the above embodiment, the adjustable base 2 is supported below the supporting portions 13 and 13 ' of the first and second structures 10 and 10 ' of the precast concrete block 1 so as to bear the shearing force transmitted by the joint structure of the end portions of the first and second structures 10 and 10 ' of the precast concrete block 1.
