Ground penetrating radar-based detecting system for road construction quality

Abstract

The invention discloses a ground penetrating radar-based detecting system for road construction quality. The detecting system comprises a vehicle-mounted ground penetrating radar system and a remote control system. The vehicle-mounted ground penetrating radar system comprises ground penetrating radar, an antenna connected to the ground penetrating radar, a master controller, a data acquisition module and a wireless short message alarm system. The remote control system comprises a control center and wireless network equipment connected to the control center. Nondestructive and continuous detection can be realized by the detection system using the ground penetrating radar; the detecting system is economical and efficient, and is easy to operate; results can be displayed visually; real-time imaging is realized by a host displayer in detection, operators can read the detecting results from the screen directly, and maps can be printed on site; measurement accuracy is high, and the detection is fast; human factors are avoided by the combination of a no carrier electromagnetic pulse technology and a high-frequency energy-collecting antenna; the system of the invention can be used to detect layer structure and internal variation of a road effectively, and the detecting speed is increased greatly when the system is vehicle-mounted.

Description

technical field [0001] The invention relates to the technology in the field of automatic detection, in particular to a road construction quality detection system based on ground penetrating radar. Background technique [0002] With the rapid development of the economy, the construction of various infrastructures has also shown a good momentum of development. Traffic is the lifeblood of the national economy, and its development directly affects the speed of national economic development. In the entire transportation system, roads are the foundation of the foundation. In recent years, the state has invested tens of billions of dollars each year to build roads, and the country's expressways have developed rapidly, and the situation is very gratifying. But at the same time, some new problems have arisen, such as the contradiction between the existing backward road inspection methods and the rapid development of road construction, how to ensure fast and good inspection of constr...

Problems solved by technology

However, this conventional method has certain limitations: firstly, the measured points are randomly selected, so the detection results are often lack of representativeness

[0004] At the same time, due to the low density of the detection points, some bad sections such as substandard compaction, small thickness, and defects inside cement concrete or asphalt are easily missed, leaving hidden dangers for subsequent engineering work.

In addition, in the daily maintenance and management of roads after they are put into use, problems such as damage, depressions, cracks, and flatness on the road surface can usually be found in time, but the hidden disasters existing in the road, such as holes and water accumulation under the road surface , empty, loose foundation, etc., but without effective detection methods, it is difficult to prevent problems before they happen. With the melting of winter ice and summer, thermal expansion and contraction, and the accumulation of stamping, it is often easy to cause major traffic accidents and cause people's lives. huge damage to property
