Traffic sensing device for intelligent road surface and paving method of traffic sensing device

Abstract

The invention belongs to the technical field of intelligent traffic roads, and particularly relates to a traffic sensing device for an intelligent road surface and a paving method of the traffic sensing device. The device comprises a plurality of piezoelectric ceramic cement concrete plates embedded in the length direction of the intelligent pavement. Each piezoelectric ceramic cement concrete plate comprises a hollow cuboid shell with an upper opening and a top cover, and grouting holes are formed in the upper surfaces of the top covers; a plurality of steel bar grids formed by a plurality of transverse steel bars and a plurality of vertical steel bars are arranged in the hollow cuboid shell at equal intervals, a plurality of piezoelectric ceramic units are arranged on the steel bar grids in an array mode, and the line spacing between every two adjacent piezoelectric ceramic units is smaller than the distance between the foremost end and the rearmost end of a wheel acting on the ground; the column distance between every two adjacent piezoelectric ceramic units is smaller than the width of the wheel acting on the ground; and the hollow cuboid shell is filled with a cement concrete slurry. According to the invention, the traffic environment and the axle load, wheelbase, running speed, wheel track, track and the like of the vehicle can be sensed comprehensively, accurately and quickly.

Description

technical field [0001] The invention belongs to the technical field of intelligent traffic roads, and in particular relates to a traffic sensing device for intelligent road surfaces and a paving method thereof. Background technique [0002] With the continuous progress and development of my country's current science and technology, intelligent services have penetrated into all aspects of life and become an inevitable trend of future development. Pavement is one of the important infrastructures of the transportation system, so the research and application of intelligent pavement technology will become the focus of realizing the intelligentization of transportation infrastructure. However, there is still no unified and clear definition and framework for smart pavement. The definition of intelligent pavement needs to be able to integrate all the current elements that can promote road innovation. Therefore, intelligent pavement can be defined as composed of specific structural ...

Problems solved by technology

However, the piezoelectric ceramic itself is relatively brittle. When it is laid on the road surface, under the continuous action of the vehicle on the road surface, it is easy to contact the aggregate, resulting in stress concentration and crushing the ceramic sheet.

On the other hand, to directly prevent the piezoelectric ceramics in the road, the external environment will greatly affect its working performance, and the rainwater seeping down on the road will corrode its surface and affect its piezoelectric effect
