Problems solved by technology

During the detection process, manual hammering is often used as the seismic source, and it is difficult to ensure that the data quality of each channel is consistent with the energy of each excitation; when the measuring point is moved, it is necessary to carry the source hammer, host computer and geophone (single-channel acquisition) to move , time-consuming and labor-intensive; in the case of high ground hardness, it is difficult for the geophone to be inserted into the ground, resulting in poor coupling effect, which in turn affects the quality of data collection

Description

technical field [0001] The invention relates to an integrated device and method of seismic source and detector for seismic wave method exploration. Background technique [0002] Seismic wave method is a common detection method. Compared with other commonly used geophysical methods such as electrical methods, this method is less affected by the environment and has higher detection accuracy for geological structures, so it is widely used in various construction engineering fields. [0003] The inventors found that the current main way to detect using the seismic wave method is to deploy one or more geophones in the detection area according to the relevant parameters of the survey line (survey line direction, offset distance, track spacing, etc.), and at the same time attach the trigger to the excitation source device, and connect the device to the host. During the detection process, manual hammering is often used as the seismic source, and it is difficult to ensure that the ...
