The working steps of geological radar in tunnel engineering inspection
2.1 Pre preparation
Firstly, before conducting detection on tunnel engineering, relevant technical personnel need to conduct pre detection inspection and evaluation on the geological radar to ensure its normal use and avoid equipment damage during detection; Secondly, the standard parameters of ground penetrating radar (GPR) transmission data should be determined and compared, and GPR detection work should be done well before detection. Different data should be annotated, and the GPR should be tested through repeated detection and multi-directional detection to improve the accuracy of GPR detection data.
2.2 Layout of geological survey lines
Firstly, before putting the geological radar into use, it is necessary to use scientific calculations and other forms to preliminarily set the distribution route of the geological radar based on the tunnel direction, area, geological conditions, etc., to ensure that the role of the geological radar is fully utilized. When determining the specific route, due to the convenience and speed of the layout work and the high flexibility, the radar survey line layout only needs to be based on the specific detection content and purpose when arranging the route; Secondly, generally speaking, the layout of geological radar survey lines includes the layout of detection points, grid routes, and detection routes. In specific detection work, the construction unit should choose the most suitable layout method based on its own engineering situation.
2.3 Sorting and Collection of Detection Data
Firstly, when using geological radar for detection, relevant personnel need to lower the antenna number of the radar and use continuous detection to ensure accurate detection of the tunnel interior and concrete structure within 15-30 minutes; Secondly, due to the different requirements for concrete quality and overall tunnel level in different tunnel projects, it is necessary to use geological radar to detect different parts according to the actual situation. During detection, relevant personnel should closely monitor the image images and related data transmitted by the geological radar, and collect them to ensure that all data is statistically analyzed. Combined with the principles of geological radar detection, the initial data should be collected and corrected to improve detection accuracy.
2.4 Geological Data Analysis and Data Interpretation
In actual geological surveys, geological radar surveys require detailed recording of survey data, comprehensive interpretation of the data, and the use of data analysis to analyze the geological characteristics and attributes. Geological radar surveys mainly include surveys of tunnel faces, geological attributes, and other aspects. Comprehensive analysis is used to make correct judgments based on data detection.
2.5 Detection and acceptance work
Firstly, after the completion of the geological radar detection work, the results detected by the geological radar should be promptly sent to the computer receiving terminal at the construction site after entering the tunnel construction area. Relevant personnel need to calculate and analyze the data, images, etc., and make corresponding adjustments to the tunnel engineering based on the detection results, and ultimately be able to conduct acceptance and evaluation of the construction; Secondly, after testing, the testing data needs to be collected and saved as information, and the equipment needs to be properly stored to ensure smooth entry into the testing work next time.
