Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to a road surface leveling device. Background Art

[0002] In urban construction, many cities use cement, asphalt, concrete and other closed surfaces to replace the original soil surface; they also like to use neat and beautiful stone slabs or cement colored bricks to pave public places such as sidewalks, open-air parking lots, courtyards and squares. While closed surfaces improve traffic and road conditions and beautify the environment, they also have a significant adverse impact on the urban ecology and climate environment. Permeable concrete pavement is permeable and can quickly eliminate water accumulation on roads and squares when it rains; when it rains in concentrated rainfall, it can reduce the burden on urban drainage facilities and prevent river flooding and water pollution. At present, during the construction of permeable pavement, a leveling device is required to polish and level the permeable concrete surface.
