Description

TECHNICAL FIELD

[0001] The present application relates to the field of mechanical, ground penetrating radar antenna support, in particular to a three-dimensional ground penetrating radar double antenna and core sampling support and method. BACKGROUND

[0002] The three-dimensional ground penetrating radar can quickly and non-destructively evaluate the road surface state. When the three-dimensional ground penetrating radar uses an air-coupled antenna to detect the road surface, it can analyze the road surface disease. When the three-dimensional ground penetrating radar uses a ground-coupled antenna to detect, it can detect the condition of the deeper position of the road. Normally, only one method can be used for detection. The ground-coupled antenna needs to be attached to the ground, and the air-coupled antenna needs to be a certain height from the road surface. However, both detection methods require a complex antenna assembly process. The air-coupled antenna needs to be installed in advance during the assembly process. The lifting support is fixed by screws and needs to be operated by two people at the same time to complete the installation. Then the antenna extension support is installed. This process requires one person to lift the extension support and the other person to install the screws. Finally, two people need to lift the radar antenna, and the other person needs to fix the antenna. The installation steps of the ground-coupled antenna are as follows: three people are needed to install the specific antenna support to the fixed position, then the ground-coupled antenna is installed on the support, the lifting handle is shaken, the antenna is adjusted to the appropriate height, and the detection begins. During the detection process, if a large ground protrusion is encountered, or the detection speed needs to be improved, the antenna needs to be manually lifted. After the detection is completed, the two supports need to be disassembled in the reverse order, which greatly wastes manpower and working time. The two antenna supports greatly occupy the space in the vehicle compartment.

[0003] After the traditional three-dimensional ground penetrating radar detection is completed, the area where the disease occurs needs to be cored for verification. However, due to the limitations of the device itself, finding the location of the disease area is an important problem. GPS often has some errors, causing inaccurate positioning. In the core sampling process, multiple people need to move the core sampling machine to the appropriate position, and then take the core. This process is complex, has a large error, and seriously wastes labor resources. SUMMARY

[0004] The purpose of the present application is to overcome the defects of the prior art and provide a three-dimensional ground penetrating radar double antenna and core sampling support and method. The support can quickly detect the road surface without affecting traffic and can quickly core verify the identified disease area, greatly improving the detection accuracy and efficiency.
