Embodiment

[0028] Embodiment: The roadbed defect identification and high polymer grouting rapid reinforcement technology of the present invention includes the following contents:

[0029] 1. Subgrade defect identification method

[0030] (1) The method of using the falling weight deflectometer (FWD) to judge the subgrade defects is as follows: use the falling weight deflectometer to conduct the deflection test on the selected road section; based on the deflection test data of the falling weight deflectometer, use the Calculation software SIDMOD backcalculates the roadbed modulus; according to the backcalculated results of the roadbed modulus, the defects of the roadbed are judged in sections to provide a basis for formulating a reasonable grouting plan;

[0031] (2) The roadbed defect identification method based on ground penetrating radar (GPR) is as follows: use ground penetrating radar to conduct continuous testing on the selected road section, and then use the dielectric characterist...

Abstract

The invention discloses a subgrade defect identification and polymer grouting fast strengthening method based on a falling weight deflectometer (FWD) and a ground penetrating radar (GPR) non-destruvtive test techniques, which utilizes the FWD and the GPR to detect and evaluate the performance of the subgrade, identify the defect of the subgrade and the position of the defect. The polymeric materials are injected into a road section which needs to treat. After the chemical reaction of the materials, the volume quickly expands and cures, thereby compacting the subgrade, filling the disengaging, removing the seeper tray, and reaching the purpose of quick repair. The method has the advantages of shortcut construction, good durability and strong pertinence, which not only saves large cost and construction period, but also facilitates the environmental protection and resource-saving, and provides a new advanced, high-efficient, economic and practical method for the subgrade defect indentification and strengthening maintenance.

Description

technical field [0001] The invention belongs to roadbed pavement detection and maintenance technology, in particular to roadbed defect recognition and high polymer grouting rapid reinforcement technology. 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 requir...
