Road construction structure in sponge city

Technical Field

The application relates to the technical field of urban roads, in particular to a road construction structure of a sponge city.

Background

The sponge city is a new generation of urban rainfall flood management concept, and means that the modern city has good ecological elasticity in the face of environmental changes and natural disasters caused by rainwater and the like a sponge, so the sponge city is also called as a water elasticity city. The sponge city recovers, accumulates and purifies the rainwater when raining, releases and utilizes the stored moisture when the city needs the water, and realizes the redistribution and free migration of the rainwater in the city.

At present, a common sponge city construction structure collects rainwater and conveys the rainwater to a planting area to provide moisture for vegetation growth.

To the correlation technique among the above-mentioned, the inventor thinks that present sponge structure construction structure is in the in-process of retrieving the rainwater and recycling, when meetting the environmental aspect of great rainfall, and the vegetation receives the irrigation of rainwater and reclaimed water simultaneously, leads to the vegetation root to receive the soaking, can lead to the mashed root of vegetation to die.

SUMMERY OF THE UTILITY MODEL

In order to promote sponge urban road construction structure to the rational utilization of rainwater, reduce the mashed root's of vegetation possibility, this application provides a road construction structure in sponge city.

The application provides a road construction structure in sponge city adopts following technical scheme:
