Embodiment 1

[0032] A road cushion disclosed in this embodiment, such as figure 1 As shown, it includes a concrete mortar surface layer 1, a steel fiber concrete layer 2, a water seepage layer 3, a mesh layer 4, a waterproof layer 5, a soil base layer 6, and a construction waste road cushion layer 7 arranged sequentially from top to bottom. Both the layer 1 and the steel fiber concrete layer 2 are provided with seepage gaps communicating with the water seepage layer 3 , and the soil base 6 is seamlessly laid on the lower surface of the waterproof layer 5 .

[0033] Wherein, the thickness of the concrete mortar surface layer 1 is smaller than the thickness of the steel fiber concrete layer 2 . And the thickness of the soil base 6 is greater than the thickness of the water seepage layer 3 . The construction waste road cushion 7 includes crushed construction waste fragments laid under the soil base 6, and the maximum particle size of the construction waste fragments is preferably below 400 m...

Embodiment 2

[0038] Such as image 3 As shown, the difference from Embodiment 1 is that the protruding member 15 is preferably disc-shaped, and its end face is parallel to the end face of the positioning disc 16, and the diameter of the protruding member 15 is greater than the outer diameter of the connecting rod 14, and at the same time The end of the connecting rod 14 is preferably fixed at the center of the protruding part 15 . The disc-shaped protrusions 15 can further enhance the nail-holding force at both ends of the connecting rod 14, so that the two ends of the connecting rod 14 are not easy to be separated from the concrete mortar surface layer 1 and the steel fiber concrete layer 2, further improving the concrete mortar surface layer. 1 and the firmness of the connection between the steel fiber reinforced concrete layer 2.

Abstract

The invention discloses a road cushion layer which solves the problem that the use effect of an existing construction waste road cushion layer is not good. According to the technical scheme, the roadcushion layer is characterized in that the road cushion layer comprises a concrete mortar face layer, a steel fiber concrete layer, a permeable layer, a knitted net layer, a waterproof layer, a soil basic layer and a construction waste road cushion layer, all of which are sequentially arranged from top to bottom, the construction waste road cushion layer comprises smashed construction waste crushed material laid below the soil basic layer, and gaps of the construction waste crushed material are filled with rubber cushion layers. By the adoption of the road cushion layer, construction waste canbe better used by the construction waste road cushion layer to replace a broken stone cushion layer, the requirement for the strength of a road surface structure and a road foundation is met, construction waste outward transport can be effectively reduced, construction cost is greatly reduced, and the use effect is better; and the gaps of the construction waste crushed material are filled with the rubber cushion layers so that the construction waste crushed material can be effectively bonded, and the firmness and stability of the construction waste road cushion layer are further improved.

Description

technical field [0001] The invention relates to road facilities, in particular to road cushions. Background technique [0002] Construction waste refers to the waste generated in the process of building and dismantling buildings. With the acceleration of urbanization and industrialization in my country, urban construction has progressed from extensional development and large-scale old city renovation to large-scale construction of residential quarters and The reconstruction and expansion of roads has resulted in the rapid generation of a large amount of construction waste, most of which are directly transported out of landfill without any treatment. It not only causes a high cost of garbage removal, but also takes up a lot of land. As a result, there is the generation of construction waste road cushion, but the use effect of general construction waste road cushion is not good, and it is easy to affect the overall bearing strength. Contents of the invention [0003] The pu...
