Asphalt concrete road structure capable of facilitating water drainage

Abstract

The invention provides an asphalt concrete road structure capable of facilitating water drainage. The asphalt concrete road structure comprises a road main body and rainwater wells arranged on two sides of the road main body at intervals, wherein the upper surface of the road main body is a road pavement; surface from the middle line to two sides of the road pavement are respectively continuous descending slopes; the asphalt concrete road structure also comprises permeable drainage zones and rainwater collection pipes; the permeable drainage zones are arranged close to two sides of the road main body and are consistent with an extension direction of the road main body; the rainwater collection pipes are buried right under permeable filtering layers; one end of each rainwater collection pipe is a low end, and the other end of each rainwater collection pipe is a high end; the low ends of the rainwater collection pipes are communicated with the rainwater wells; a plurality of water permeating holes are formed in pipe bodies of the rainwater collection pipes at the upper parts of axial symmetrical planes. The asphalt concrete road structure provided by the invention is capable of rapidly discharging the rainwater on the road pavement, preventing the rainwater from retaining on the road pavement to form water accumulation and waterlogging, reducing the amount of rainwater permeatingdownwards from the road pavement, alleviating the soaking of the roadbeds by rainwater, improving the anti-scouring capability of the roadbeds and achieving the effect of prolonging the service lifeof the asphalt concrete pavements.

Description

technical field [0001] The invention relates to a pavement structure, in particular to an asphalt concrete road structure favorable for drainage. Background technique [0002] The emergence of the urban heat island effect has led to an increase in the probability of urban rainstorms, which will bring concentrated precipitation in a short period of time, which in turn will cause urban roads to accumulate water and waterlogging. Traditional roads only drain water through the rainwater wells located on both sides of the road surface, and the drainage volume per unit time is relatively limited. When a heavy rain occurs, a large amount of rainwater has no time to enter the rainwater wells and can only infiltrate slowly through the road surface. The infiltrating rainwater is easy to soak and soften the roadbed. This leads to subsidence of the road surface and reduces the service life of the road.
