The complementary reverse slope of four couples of last stage body and following stage body periphery can be trapezoidal, and the sphere cylindrical of paving block upper surface can be tangent with two pairs of fillet surfaces of last stage body periphery.

During laying, basic unit can be sand cushion or hardcore bed, behind the good ground of levelling, above the dumb-bell shape paving block is laid on side by side, make the inside and outside corresponding interlock in inclined-plane of adjacent two blocks of paving blocks, supporting surrounds cavity by its fillet surface and cylinder between the adjacent paving block mutually, after paving block was laid, grass planting banketed in cavity.By the paving that the utility model dumb-bell shape paving block is constructed, can be used for kind of the grass that fixes the sand of parking lot, road and desert region.

The dumb-bell shape paving block that the utility model can be planted grass by introduce four pairs of complementary reverse slopes make original monolithic elements stressed be transformed into whole stressed.When single paving block load-bearing, because last stage body and following stage body perimeter ramps is engaged, squeezing action, make this paving block not only be subjected to the active force that adjacent paving block makes progress, also be subjected to simultaneously level to pressure, even paving block forms the side direction compressive pre-stress, on a certain block of paving block, be subjected to wheel like this and do the time spent, the paving has globality, can work as continuous slab.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
