A pre-processing method and system for treating road grass-roots diseases with polymers

Abstract

The invention discloses a preorder treatment method and a preorder treatment system for governance of road base diseases through high polymers. The method includes the following steps: (S1) constructing a three-dimensional coordinate system; (S2) performing ground detection to the road base, and drawing a ground projective map in the three-dimensional coordinate system according to detected collapse empty zones; (S3) selecting a cut-in point according to the ground projective map; (S4) cutting the cut-in point through to form a cut-in entrance; (S5) emitting a shock wave into the collapse empty zones, and reshaping the collapse empty zones; (S6) detecting the internal shapes of the collapse empty zones in real time, and establishing a virtual model; (S7) presetting a curvature threshold valve; (S8) monitoring the surface curvature of the virtual model in real time, comparing the maximum surface curvature with the curvature threshold valve, and controlling operation status of the shock wave according to a comparison result; and (S9) calculating the volume of the virtual model. The system includes a control device, a supersonic shock device, a detection device and a human-machine interaction device, wherein the control device is connected to the supersonic shock device, the detection device and the human-machine interaction device. The method and the system can be used for calculating the volumes of the collapse empty zones accurately.

Description

technical field [0001] The invention relates to the technical field of road maintenance and repair, in particular to a pre-processing method and system for treating road grass-roots diseases with polymers. Background technique [0002] At present, my country's high-grade highway construction is in a stage of rapid development. As an important part of the pavement structure, the subgrade not only provides the basic conditions for vehicles to run on the road, but also serves as a supporting structure for the pavement, which plays a vital role in the performance and service life of the entire pavement. However, due to the quality of the roadbed, many pavements have insufficient compaction or voids. After opening to traffic, early damage to the pavement, such as subsidence and cracking, will soon appear. Soon after completion, it will not be able to meet the needs of vehicle traffic, and the amount of maintenance projects will increase. The larger the size, the higher the requi...
