Permeable pavement

Technical Field

The utility model relates to a wood working machinery especially relates to a permeable pavement.

Background

In urban construction, many cities adopt closed earth surfaces such as cement, asphalt, concrete and the like in large quantities to replace the original soil surfaces; it is also popular to pave sidewalks, open parking lots, courtyards, squares and other public places with neat and beautiful stone slabs or cement color bricks. The closed earth surface can improve the traffic and road conditions and beautify the environment, and can also have obvious adverse effects on the urban ecological environment and the climatic environment; the surface of the modern city is gradually hardened and covered by water-blocking materials due to the closed surface and the high-rise building, water is difficult to seep downwards, precipitation quickly becomes surface runoff and enters a river channel or underground drainage pipeline, and an ecological artificial desert is formed.

Some developed countries begin to research pavements with water permeable functions from the last 70 th century, and apply the pavements to courtyards, sidewalks, bicycle lanes, public squares, open parking lots, roads in parks, two sides of the roads, central isolation belts and the like, so that water permeable and air permeable spaces of cities are increased, and good effects on adjusting microclimates of the cities and keeping ecological balance are achieved. After the 90 s in the 20 th century, the conventional material pavement is replaced by the pavement with the water permeable function, and the general experience of urban construction in developed countries is already provided. The road surface with the water permeable function ensures that rainwater permeates into the ground from the road surface, can quickly eliminate the water accumulation phenomenon of roads and squares when raining, and can increase the comfort level of urban living; when the rainfall is concentrated, the burden of urban drainage facilities can be lightened, and the flooding of rivers and the water body pollution are prevented.

The Chinese patent with the publication number of CN206828400U discloses a precast concrete permeable pavement slab and a permeable pavement, wherein the surface layer of the permeable pavement slab is a permeable surface layer or an impermeable surface layer, the length of the pavement slab is 400-1800 mm, the width of the pavement slab is 300-900 mm, and the thickness of the pavement slab is 100-200 mm, the permeable pavement slab has a cambered surface gradient of 0.5- ~ 2% from the center of the surface layer to the periphery, and the permeable pavement slab is a soil base layer, a leveling adhesive layer and a precast concrete permeable pavement slab from bottom to top.
