Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.

A shock-absorbing environment-friendly roadbed structure is shown in figures 1-3, and is provided with a cushion layer 1, a base layer 2, a sponge layer 3, a rubber layer 4, a gravel layer 5, a concrete layer 6 and a surface layer 7 in sequence from bottom to top, wherein the cushion layer 1, the base layer 2, the sponge layer 3, the rubber layer 4, the gravel layer 5, the concrete layer 6 and the surface layer 7 form a regular trapezoid, the surface of the surface layer 7 is provided with a plurality of water inlet holes 71, and the water inlet holes 71 penetrate through the concrete layer 6 and are communicated with the gravel layer 5;

the gravel layer 5 is formed by piling and spreading gravel, and the gravel is separated from each other by a gap, so that rainwater can enter the gravel layer 5 through the water inlet hole 71.

Detachable is provided with a plurality of buffer boards 21 and damping shock absorber 23 in basic unit 2, buffer board 21 sets up along the trend interval of road bed, the top surface of buffer board 21 supports and leans on at sponge layer 3, the one end of damping shock absorber 23 is fixed on bed course 1, the other end is fixed on buffer board 21, damping shock absorber 23 plays the supporting role to buffer board 21, buffer board 21 plays the supporting role to sponge layer 3, damping shock absorber 23 also plays the cushioning effect to the holding down force of top.

Still include side slope layer 8, side slope layer 8 sets up at bed course 1, basic unit 2, sponge layer 3, rubber layer 4, metalling 5, concrete layer 6 and top layer 7's side, side slope layer 8 and bed course 1, basic unit 2, sponge layer 3, rubber layer 4, metalling 5, concrete layer 6, top layer 7 form whole roadbed structure, still be provided with apopore 81 on the side slope layer 8, apopore 81 intercommunication metalling 5, rainwater accessible apopore 81 in the metalling 5 flows.

The cross-section of buffer board 21 is "n" type, and both sides face expands to be the slope form, and the top surface of buffer board 21 can vibrate from top to bottom, to the pressure that increases suddenly in the top, plays the cushioning effect, and the bottom side of buffer board 21 still is provided with a plurality of mounting holes 22, and the double-screw bolt passes mounting hole 22, can fix buffer board 21 on bed course 1.
