Description

TECHNICAL FIELD

[0001] The utility model relates to a self -moving dismounting formula ground penetrating radar detection device for track detection. BACKGROUND

[0002] Ground penetrating radar is a kind of geophysical method using antenna to emit and receive high-frequency electromagnetic wave to detect the internal substance characteristics and distribution law of medium. With the high-speed economic development, the development and utilization intensity of urban underground space is increasing, and the stability of urban shallow geology causes a certain degree of influence and damage, which lays hidden dangers for track collapse accident and affects the urban operation order, so the detection of underground disease and uneven settlement of subway and railway subgrade changes the post-incident rescue and management into prevention, which is beneficial to the safe operation of city. In order to reduce the occurrence of accidents, the underground disease detection of the road and track involving construction section is carried out, and the advanced prediction and early management are very important. Due to the high precision and high efficiency of ground penetrating radar detection, it is currently used in many fields such as archaeology, mineral exploration, disaster geological survey, engineering quality detection, building structure detection and military target detection. When ground penetrating radar detects track subgrade structure, high-frequency electromagnetic pulse wave is emitted to the underground by working antenna, when the dielectric constant of adjacent structure layer material is different, electromagnetic wave is reflected and transmitted at the interface of structure layer, after multiple reflection and transmission, part of electromagnetic wave energy is gradually attenuated, another part of electromagnetic wave returns to the ground and is received by working antenna, and the track structure quality is related to the reliability and long-term stability of track operation, so it is necessary to detect the actual thickness, moisture content and compactness of each structure layer of track. There may be blind area in the detection process of ground penetrating radar, when the target depth exceeds the penetration depth of radar set frequency band, it is difficult to be found, and angle problem or shielding will cause radar unable to detect target. Low-frequency ground penetrating radar has relatively poor detection resolution when detecting target in short distance, and cannot accurately capture the small problems on track. Selecting appropriate antenna frequency can ensure the reliability of detection result, and improper antenna frequency selection will affect the resolution and penetration of detected object, and when data is collected in continuous mode without measuring wheel, the antenna moving speed is difficult to keep constant.

[0003] The existing ground penetrating radar cannot adjust the relative position of the detected track, and cannot effectively detect the basic conditions of the track and the roadbed outside the track. In addition, it cannot replace the antenna of different frequencies in time to adapt to the depth of the track roadbed, and cannot adapt the radar antenna, which limits the application of ground penetrating radar detection technology in track roadbed detection, and affects the user's use and data acquisition efficiency. Moreover, it cannot perform adaptive preprocessing of ground penetrating radar raw data according to different detection positions, different frequency antennas and other conditions, cannot accurately obtain radar maps with high resolution and high signal-to-noise ratio, and cannot guarantee the accuracy of disease identification.
