Assembly type pavement system based on piezoelectric transduction technology

Abstract

The invention relates to a piezoelectric transduction technology-based assembled pavement system, which comprises a pavement structure and an energy acquisition device, the pavement structure comprises an asphalt wearing layer, a cement concrete pavement slab, a base layer and a roadbed which are arranged in sequence from top to bottom, and the energy acquisition device comprises a piezoelectric energy acquisition module and a transmission conductor which are connected with each other. The cement concrete pavement slab is a preset assembly type panel, and the upper surface of the cement concrete pavement slab is provided with an installation groove used for installing the piezoelectric energy collection module and the power transmission wire. Compared with the prior art, the integrity and synergism of the pavement and the piezoelectric energy acquisition module can be improved, and the service life of the pavement structure and energy acquisition is prolonged; the energy collection efficiency and the electrical stability are improved; the piezoelectric energy acquisition module layout problem is solved, maintenance and upgrading are facilitated, the construction progress is accelerated, and the construction quality is improved.

Description

technical field [0001] The invention belongs to the field of road engineering, and relates to a road energy collection device, in particular to an assembled road system based on piezoelectric energy conversion technology. Background technique [0002] In view of the typical characteristics of the road transportation industry, such as large energy consumption, high environmental pollution, and low intelligence level, mining green energy in the road area has become an important driving force for the realization of road green and intelligent development. During the design service period of the pavement, the pavement has been subjected to more than ten million times of axle loads, resulting in continuous deformation and vibration. It is estimated that on a 1-kilometer-long lane, when the flow of trucks exceeds 600 vehicles / hour, more than 150 kilowatts of mechanical energy can be generated per hour. These energies are eventually dissipated as heat energy inside the asphalt pave...
