Description

Technical Field

[0001] The invention belongs to the field of underground structure quality detection, and in particular relates to a geological radar auxiliary measurement device capable of simultaneously detecting multiple measurement areas. Background Art

[0002] Geological radar is an electronic device that uses high-frequency electromagnetic wave technology to detect underground objects. It is often used to detect the structural quality of cable tunnels or the external cavities of tunnels. During the detection process, in order to ensure the accuracy of the measurement signal, the geological radar antenna needs to be closely attached to the inner surface of the tunnel to be inspected and move along the designated measurement line.

[0003] The geological radar antenna models that are usually used more in cable channel structure detection are 500MHZ, 800MHZ and 900MHZ. The weight of these antennas plus the weight of the supporting accessories are usually more than 3kg. People need to hold the antenna for a long time in the tunnel, which is very hard, and it is often difficult to ensure that the antenna is always in contact with the surface of the tunnel lining to be detected, which affects the collection quality of the detection signal; in addition, the cross-sectional diameter of the cable tunnel is usually more than 2.5m. Due to the limited height of people, it is often difficult to directly measure the position of the tunnel roof or top arc. At present, during detection, detection personnel often need to use the support pole supporting the geological radar to lift the antenna for detection, but the actual operation is extremely difficult, the personnel efficiency and work efficiency are very low, and it is difficult to ensure that the radar antenna is in close contact with the inner surface of the tunnel. Therefore, the quality of the detection signal is difficult to guarantee.

[0004] Moreover, during the inspection process, a tunnel often needs to set up multiple measuring lines in the vault / top plate, side wall and other parts, which requires the inspectors to make multiple round trips for inspection, resulting in low inspection efficiency. Summary of the invention
