Detailed Description

In order to make the technical solutions of the present invention better understood, those skilled in the art will now describe the present invention in further detail with reference to the accompanying drawings.

The utility model provides pervious concrete with a buffering function, which comprises a base layer 1, wherein the top of the base layer 1 is connected with an absorption layer 2, the top of the absorption layer 2 is connected with a first plastic layer 3, the top of the first plastic layer 3 is connected with a water-resisting layer 4, the top of the water-resisting layer 4 is connected with a plurality of bulges 5, a second plastic layer 6 is connected between every two bulges 5, the bottom of the second plastic layer 6 is provided with a plurality of water drainage holes 7, and the water drainage holes 7 sequentially penetrate through the water-resisting layer 4, the first plastic layer 3 and the absorption layer 2 and extend to the bottom surface of the base layer 1.

Further, in the above technical solution, the left and right sides of each protrusion 5 are provided with arc surfaces.

Furthermore, in the above technical scheme, the first plastic layer 3 is prepared by mixing PU particles, pigments, additives and fillers, so that the first plastic layer 3 has the characteristics of good flatness, high compressive strength, proper hardness and elasticity and stable physical properties, thereby providing a certain buffer for the foundation and ensuring that pedestrians feel comfortable when walking.

Further, in above-mentioned technical scheme, second plastic layer 6 sets up to the arc, second plastic layer 6 comprises bottom and surface course, the bottom is owing to single liquid type PU and elastic rubber granule combine to make, the surface course adopts the EPDM micelle to make, makes second plastic layer 6 elastic stability, and has the advantage that gas permeability and drainage performance are good to can make the inside of the second plastic layer 6 reachs wash port 7 of the too fast infiltration of ponding between arch 5.

Further, in the technical scheme, the absorption layer 2 is made of asphalt, cork and solid wood in a mixed mode, and the thickness of the absorption layer is set to be 2.5-5.0mm, so that the absorption layer 2 has the elastic buffering characteristic of wood and asphalt, and the foot feeling of pedestrians is improved.

Further, in the above technical solution, the water-resisting layer 4 is made of cohesive soil containing a small amount of gravel and sand, so as to reduce the influence of accumulated water on the absorbing layer 2 and the first plastic layer 3 during drainage.
