[0058] (1) Basic point positioning

[0059] (1.1) Select a road section suitable for burying the pressure power generation system, and design the buried layout and wiring of the pressure generators in the road section. The pressure generators are arranged along the vertical and horizontal lines of the road, and the vertical layout is arranged at an equidistant distance of 2.5m. Two roads are installed in each horizontal row of each lane. The pressure generator, the wires of...

Embodiment 2

[0096]Embodiment 2: The asphalt pavement pressure generator embedding method of the present invention is implemented in a certain two-way six-lane expressway pressure generator section, and the project scale is 500m expressway lane, adopting a rectangular pressure generator with a length, width, 30cm×30cm, and a height of 8cm . The specific operation method and steps are as follows:

[0097] (1) Basic point positioning

[0098] (1.1) When the pavement of the lower layer of the road section is completed but the surface layer of asphalt mixture is not paved, the pressure generator embedding layout and wiring design of the road section shall be carried out first. Two pressure generators are arranged in each horizontal row in each lane (arranged on both sides with high frequency of wheel overrun), and the wires of the pressure generators enter the road shoulder from the pressure generator to the outside of the lane, and then gather and connect to the peripheral lines;

Embodiment 3

[0129] Embodiment 3: The embedding method of the asphalt pavement pressure generator of the present invention is implemented in a certain two-way six-lane expressway pressure generating circuit section, the project scale is 300m expressway carriageway, and a commercially available electric generator with length × width 28.5mm × 26.5mm and a height of 8mm is adopted. Rectangular pressure generators are arranged longitudinally and transversely along the road with a longitudinal interval of 4m. The specific operation method and steps of pressure generator embedding are the same as in Example 2. After the embedding step is completed, let it dry naturally for 18 hours, then add an epoxy resin anti-skid coating to the road surface in the entire pressure generator embedding area, and then dry it naturally for 7 hours. The entire construction process is completed after the epoxy resin is cured.

Abstract

The invention provides an asphalt pavement pressure generator embedding method and belongs to the technical field of highway engineering piezoelectric pavement paving. The method includes the steps that basic point localization, fixed point pit excavation, circuit slotting, pressure generator embedment, wire embedment and antiskid coating laying. A road section suitable for pressure generator embedment is selected, two fixed point piles A and B are driven to the positions outside a road shoulder of the road section, the distance dA between each point and the point A and the distance dB between each point and the point B are measured and recorded, after a face layer of the road section is laid, the point A and the point B are measured, compared with data recorded previously, reserved embedding points of pressure generators are found, a pit is excavated in each embedding point, and each pressure generator is placed in the corresponding pit, cushioned flatly and fixed through asphalt mastic and then encapsulated through a gap sealing and filling material. The gap sealing and filling material is obtained by compounding SBS modified asphalt and compound modified kieselguhr. Embedding links are tightly combined, a construction technology is simple, the pressure generators can be effectively fixed, damage to a pavement is greatly reduced, and embedding work of the pressure generators is effectively guided.

Description

technical field [0001] The invention relates to a method for embedding an asphalt pavement pressure generator, which belongs to the technical field of highway engineering construction. Background technique [0002] Pressure power generation has the advantages of simple structure, no heat generation, no electromagnetic interference, no pollution, and easy miniaturization and integration, and can meet the power demand of low energy consumption products. The core content of the piezoelectric technology for asphalt pavement is to convert the vibration energy of the vehicle during driving on the asphalt pavement into electrical energy through the piezoelectric energy harvesting device. This requires that the pressure generator should be embedded in the surface layer of the asphalt pavement, but burying the pressure generator will inevitably cause damage to the asphalt pavement, and there are very few engineering examples of pressure power generation, and its buried construction m...
