Pervious concrete pavement slab system and pavement slab rainwater collection system

Abstract

The invention relates to the technical field of pervious concrete pavements, in particular to a pervious concrete pavement slab system and a pavement slab rainwater collection system, , thereby solving technical problems in the background art. The pervious concrete pavement slab system comprises a cushion layer, a base layer, a leveling layer and a pervious concrete pavement slab which are sequentially arranged from bottom to top. The pervious concrete pavement slab is arranged on the upper surface of the leveling layer. The pervious concrete pavement slab comprises a pervious concrete pavement slab lower surface layer and a pervious concrete pavement slab upper surface layer; a drainage pipe is arranged at the bottom of the base layer; and a plurality of water permeable holes are formed in the pipe wall of the drainage pipe. The pervious concrete pavement slab system prepared from the solid waste material can achieve the effects of collecting and discharging rainwater, effectively supplementing underground water and relieving sharp drop of urban underground water, thereby realizing urban rainwater management and water pollution treatment effectively. The pervious concrete pavementslab system has higher economic benefits and social benefits.

Description

technical field [0001] The invention relates to the technical field of permeable concrete pavement, in particular to a permeable concrete pavement system and a pavement rainwater collection system. Background technique [0002] Every summer, Chinese cities are frequently hit by heavy rainstorms. After the heavy rains, cities often experience different degrees of water accumulation, resulting in traffic jams, power outages, and flooded houses. The main reason for this situation is that the roads in Chinese cities are not permeable. [0003] In urban construction, many cities use a large number of cement, asphalt, concrete and other closed surfaces to replace the original soil surface; for public places such as sidewalks, open-air parking lots, courtyards and squares, they also like to use neat and beautiful stone slabs or cement color. Brick paving; however, the closed surface has adverse effects on rainwater infiltration while improving traffic and road conditions and beaut...

Problems solved by technology

[0003] In urban construction, many cities use a large number of cement, asphalt, concrete and other closed surfaces to replace the original soil surface; for public places such as sidewalks, open-air parking lots, courtyards and squares, they also like to use neat and beautiful stone slabs or cement color. Brick paving; however, closing the surface while improving traffic and road conditions and beautifying the environment has had an adverse effect on stormwater infiltration

[0004] The permeable concrete pavement has water permeability, and it can quickly eliminate the water accumulation in roads and squares when it rains. However, the water permeability of the current permeable concrete pavement system still needs to be improved, and it cannot be discharged in time under the condition of heavy rainfall. Accumulated water will inevitably lead to urban waterlogging during the rainy season, seriously affecting the normal life and travel of citizens; in addition, the existing permeable pavement mostly uses natural sand and gravel, and the construction cost is relatively high
