Abstract

The invention discloses an ecological road engineering system, and belongs to the technical field of city road building. A carriageway and a non-motor way are each provided with a water-permeable bituminous pavement, namely a porous bituminous pavement, the porosity is higher than 20% after compaction is carried out, and drainage channels can be formed inside a bituminous mixture. Rainfall runoff on the pavements is collected into water storage devices embedded into a medium divider and a lateral divider and is gradually and slowly released to surrounding soil, and therefore the growth requirement of plants is met. By means of the ecological road engineering system, self-organization irrigation of the green belt plants is completed, the manual irrigation cost is reduced, and water resources are saved; soil irrigation is more thorough, a small amount of manual irrigation and a small amount of rainfall enable water to difficulty reach a soil layer with a certain depth, and therefore growth of tree root systems is not facilitated; meanwhile, a real-time monitoring system provides scientific data information for maintenance and effective detection of the ecological road engineering system; manual energy resources and power input are not needed in the complete system, the operation and maintenance cost is low, and the practical value is achieved; and through practices in one year, the system better runs, and the popularization value is achieved.

Description

technical field [0001] The invention belongs to the technical field of urban road construction, and in particular relates to an ecological road engineering system. Background technique [0002] Road surface water has always been an important issue in traffic safety and road management and maintenance, especially in rainy areas in southern my country, road surface water will cause vehicle tires to slip, becoming a safety hazard, and water splashing not only affects pedestrians, but also pollutes vehicles body, increasing vehicle cleaning costs and water consumption. The surface drainage of ordinary asphalt or cement pavement can only pass through the gutter outlet, which takes a long time and is easy to be blocked. Water will also form in shallow recesses on the road surface, making it difficult to discharge. [0003] As an important part of the urban green space system, road greening has attracted more and more attention because of its outstanding ecological functions and en...
