Problems solved by technology
[0005] The inventor found that in the actual operation process, the transmitting coil is usually bundled together with multi-turn coils, and the operator holds the square PVC plastic support frame and the receiving return rod to detect the tunnel face. It is difficult to measure manually; and the existing support frame is difficult to ensure the quality of the coil loop, and the size and weight of the equipment are large, which makes it difficult to measure the transmitting and receiving coils according to the predetermined height and angle of the measuring line, thus affecting the accuracy and accuracy of the measurement results. quality, and the efficiency of construction measurement is low in projects with large tunnel faces

Description
technical field [0001] The present disclosure relates to the technical field of transient electromagnetic detection, and in particular, to a solid-source transient electromagnetic automatic scanning device and method for tunneling. Background technique [0002] The statements in this section merely provide background related to the present disclosure and do not necessarily constitute prior art. [0003] The transient electromagnetic method uses a grounded line source or an ungrounded return line to transmit a primary pulsed magnetic field to the detection target, and uses a coil to observe the secondary induced eddy current field caused by the detection of the target medium during the intermittent period of the primary pulsed magnetic field to detect the resistivity. Clearly detect caves, fissures, and water in the target. [0004] The transient electromagnetic method measurement device is composed of three parts: a transmitting coil, a receiving return bar, and a data proc...
