Problems solved by technology

[0003] The inventor found that at present, when performing seismic image detection on tunnel vaults and other positions, operators need to be lifted to a certain height by trolleys, etc., and the safety is poor; when performing long-distance detection, not only is the efficiency low, but the detection The accuracy of the data is also difficult to guarantee
At the same time, the form of source excitation is still dominated by manual hammering, which cannot guarantee that the data quality of each trace is consistent with the energy of each excitation
In addition, in the surrounding rock with high hardness, it is difficult for the geophone to be tightly coupled with the surrounding rock, which further affects the quality of data acquisition

Description

technical field [0001] The invention relates to an assembled vehicle-mounted seismic image detection system and method suitable for inside a tunnel. Background technique [0002] In the process of tunnel construction, the seismic wave method is often used as a method to detect unfavorable geological bodies. Due to the complex situation in the tunnel, the multi-channel seismic wave method is sometimes difficult to implement, so the single-channel seismic imaging method is often used to better adapt to the environment in the tunnel. [0003] The inventor found that at present, when performing seismic image detection on tunnel vaults and other positions, operators need to be lifted to a certain height by trolleys, etc., and the safety is poor; when performing long-distance detection, not only is the efficiency low, but the detection The accuracy of the data is also difficult to guarantee. At the same time, the form of source excitation is still dominated by manual hammering, ...
