Road with seepage and storage functions and construction method thereof

Abstract

The invention provides a road with seepage and storage functions and a construction method thereof. The road sequentially comprises a subbase layer, a moisture transmission fiber layer, a cement stable base layer and a permeable cement concrete surface layer from bottom to top. The moisture transmission fiber layer is formed by laying fibers with communication holes inside, the lower ends of the fibers extend to the subbase layer, and the upper ends of the fibers extend to the cement stable base layer. When it rains, rainwater rapidly infiltrates downwards through the permeable cement concretesurface layer and is accumulated in the cement stable base layer and the subbase layer to form a micro reservoir, and then underground water is supplemented to the foundation, accumulated water on the road surface is avoided or reduced, waterlogging is reduced, flood disasters are reduced, and safety is guaranteed; in high-temperature dry weather, accumulated moisture is guided to the road surface under the capillary action of the fibers, and through the evaporation effect, the air temperature of the road surface and the ground surface can be reduced, the humidity can be increased, air pollutants can be reduced, the ecological environment can be improved, the comfort level can be improved, and the microclimate adjusting function can be achieved.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering and municipal construction, and in particular relates to a road with seepage storage function and a construction method thereof. Background technique [0002] Traditional pavements mainly use concrete and asphalt to pave the surface, and at the same time use a dense cement stabilization layer as the base. Although this pavement structure has good mechanical properties, it is dense and impermeable. When it rains, a large amount of rainwater collects in low-lying areas along the impermeable road surface, and the drainage system is overwhelmed. It cannot discharge the collected rainwater into the river in time, forming internal waterlogging, which leads to the phenomenon of "the city looks at the sea". It also had little effect. This situation has various safety hazards: people slip and fall and are injured; vehicles produce water mist, which affects the visibility of vehicles...

AI Technical Summary

Problems solved by technology

When it rains, a large amount of rainwater collects in low-lying areas along the impermeable road surface, and the drainage system is overwhelmed. It cannot discharge the collected rainwater into the river in time, forming internal waterlogging, which leads to the phenomenon of "the city looks at the sea". with little success

This situation has various safety hazards: people slip and fall and are injured; vehicles produce water mist, which affects the visibility of vehicles behind; it causes sewer backflow, sewage cross flow, and infectious diseases; it not only seriously affects people's travel, but also causes a large number of safety accidents. Management is a huge hassle

At the same time, because the asphalt pavement is black and the concrete pavement is gray, they have a great absorption and accumulation effect on the heat of sunlight, which leads to a significant increase in the temperature of the pavement in the high temperature season in summer, resulting in a heat island effect, which affects the living environment and environment of the surrounding people. Biological reproduction reduces the comfort of life
